Proximity television and audiences: tensions in the media territory / Televisión de proximidad y audiencias: tensiones en el territorio mediático

RESUMEN Objetivo: Las audiencias locales que se sitúan fuera de las capitales y de las grandes urbes deben conformarse con la información y contenidos televisivos nacionales, perdiendo la conexión con sus territorios debido al marcado centralismo de los medios capitalinos. Este artículo caracteriza las tensiones de las audiencias locales del norte de Chile en relación con su televisión local, también denominada de proximidad. Materiales y métodos: La metodología es cualitativa, realizándose grupos focales con las audiencias de seis comunas de la región de Coquimbo que tuviesen televisoras locales operativas y que declarasen ver periódicamente medios locales. Resultados: Entre los hallazgos se destaca el interés y el requerimiento de la ciudadanía por las noticias locales en un claro sentido de proximidad y cercanía con su territorio, detectando además otras demandas sociales, políticas, culturales y educativas de las audiencias que podrían ser canalizadas por las televisoras locales. Se evidencia un distanciamiento y crítica hacia contenidos sensacionalistas de la televisión nacional, siendo el centralismo informativo una de las razones para la poca empatía hacia estos medios de comunicación. A juicio de los participantes, las tensiones entre lo local y lo capitalino no solo se aprecian a nivel país, sino también entre capitales regionales, provincias y comunas, siguiendo la división político-administrativa de Chile. Conclusiones: Se concluye que existe una marcada preferencia por el contenido de proximidad, lo que se explica en parte por el alejamiento y crítica que se declara hacia los medios de cobertura nacional. Se plantean como tensiones la falta de espacios de comunicación y promoción del diálogo social que les permita a las audiencias ser escuchadas por sus actores políticos locales y regionales, desaprovechando el interés de la televidencia local por contenidos de proximidad que les permitan crecer, desarrollarse y lograr una mayor participación ciudadana en el ecosistema medial chileno.

ABSTRACT Objective: Media centralism and the lack of attention to the preferences and demands of local audiences is an obvious reality that must be faced by those who live outside large cities and capitals, understanding that there are audiences that demand local content, but that must settle for aprogrammingproduced from and for the capital, even more so when it comes to the Chilean television system. This article characterizes the tensions of local audiences in northern Chile in relation to their local television, also called proximity. Materials and methods: The study carried out a qualitative methodology, since it seeks to understand human behavior in a given territory and historical moment. The data collection was carried out using the technique of focus groups in order to explain and deepen the situations of people as local audiences and their feelings and thoughts on various problems. The focus groups discussed their local television and their link with national television considering the informational centralism and political centralism within the Coquimbo Region. The sample corresponds to the audience of cities belonging to urban and rural communes of the Coquimbo Region, in Chile, where there are local television media and that have declared their intention to migrate to digital television. The cities that are part of the study are: Andacollo, La Serena, Los Vilos, Illapel and Salamanca. For recruitment, the snowball method was used, with a total of 52 participants. All the participants were over 18 years of age with a residence of more than 10years in the city. There was gender balance. Six focus groups were held in neighborhood offices in each city. The sessions were recorded and later transcribed, being systematized using the Atlas.tisoftware, version 9. Resulted: The results are described through three categories of analysis, regarding the opinions of the audiences: 1) Local information 2) National television: positive and negative aspects and 3) Information centralism and media demands. 1 ) Local information as a center of interest: Audiences place local news among their preferences. In each focus group, the informative genre of these media was highly valued and required. It represents a fundamental demand when evaluating local television positively. 2) Link with national television coverage: Along with the preference for local news, there is also an unfavorable opinion towards national news and towards the journalistic routines of the capital television stations whose coverage privileges the events that occurred in the Metropolitan Region in the information guidelines, often falling into sensationalism, especially when it comes to police court facts. 3) Information centralism and media demands: in the opinion of the participants, the tensions between the local and the capital are not only appreciated at the country level, but also between regional capitals, provinces and communes, following the political-administrative division of Chile. Conclusions: Regarding the characteristics of local television consumption, a first conclusion was the confirmation of the interest and consumption of local audiences in content that addresses issues related to their environment, an issue that is in line with previous studies on communication and local television. Similar to national television consumption, local news represented the preferred content. If there is a fire or a traffic accident in the city, audiences want to see it on their local television and, hopefully, live or as instantly as possible. This is informative content that does not compete in any case with national television, as it deals with local news events. Unless something out of the ordinary happens, whose connotation is national and in this case -the fewest times- the city, province or region makes news and appears nationally. A very important link was detected between local audiences with their own territories. The link was verified through two factors: a) the expectations of seeing local content not only on themes about their cities, but also from geographically broader places, such as communes, provinces or the Coquimbo Region itself; b) a large part of the social demands that underlie the opinions of the audiences surroundfeelings of belonging, desire for decentralization and local development. The need for representation of local audiences is verified, that is, seeing their territories on the screen, feeling reflected on national TV through their cultural, territorial, geographical, touristic, or other particularities is the cause that is associated Local (non-capital) audiences arepart of a marginalized sector from a political and economic point of view. In this sense, there is a glimpse of a disconnection between the political/public world that promotes actions that should benefit the community, but that fail to reach potential users in a good way. In the same line of discussion, social demands for access to public information that benefits them and brings them closer to local political actors are detected. Know and understand the territorial public policies that result in a better quality of life. These social/political demands are intermingled with the media needs that could be channeled into more spaces to debate, talk and express their opinions to participate in the local public debate.

Environmental sympatry through time: spatio-temporal distribution and conservation status of two sympatric anuran species (Leptodactylidae) in South America / Simpatría ambiental a través del tiempo: distribución espacio-temporal y estado de conservación de dos especies de anuros simpátricos (Leptodactylidae) en América del Sur

Abstract Introduction: Leptodactylus latinasus and Physalaemus cuqui are sympatric anuran species with similar environmental requirements and contrasting reproductive modes. Climatic configuration determines distribution patterns and promotes sympatry of environmental niches, but specificity/selectivity determines the success of reproductive modes. Species distribution models (SDM) are a valuable tool to predict spatio-temporal distributions based on the extrapolation of environmental predictors. Objectives: To determine the spatio-temporal distribution of environmental niches and assess whether the protected areas of the World Database of Protected Areas (WDPA) allow the conservation of these species in the current scenario and future. Methods: We applied different algorithms to predict the distribution and spatio-temporal overlap of environmental niches of L. latinasus and P. cuqui within South America in the last glacial maximum (LGM), middle-Holocene, current and future scenarios. We assess the conservation status of both species with the WDPA conservation units. Results: All applied algorithms showed high performance for both species (TSS = 0.87, AUC = 0.95). The L. latinasus predictions showed wide environmental niches from LGM to the current scenario (49 % stable niches, 37 % gained niches, and 13 % lost niches), suggesting historical fidelity to stable climatic-environmental regions. In the current-future transition, L. latinasus would increase the number of stable (70 %) and lost (20 %) niches, suggesting fidelity to lowland regions and a possible trend toward microendemism. P. cuqui loses environmental niches from the LGM to the current scenario (25 %) and in the current-future transition (63 %), increasing the environmental sympathy between both species; 31 % spatial overlap in the current scenario and 70 % in the future. Conclusion: Extreme drought events and rainfall variations, derived from climate change, suggest the loss of environmental niches for these species that are not currently threatened but are not adequately protected by conservation units. The loss of environmental niches increases spatial sympatry which represents a new challenge for anurans and the conservation of their populations.

Resumen Introducción: Leptodactylus latinasus y Physalaemus cuqui son especies de anuros simpátricos con requerimientos ambientales similares y modos reproductivos contrastantes. La configuración climática determina los patrones de distribución y promueve la simpatría de los nichos ambientales, pero la especificidad/selectividad determina el éxito de los modos reproductivos. Los modelos de distribución de especies (MDE) son una herramienta valiosa para predecir distribuciones espacio-temporales basadas en la extrapolación de predictores ambientales. Objetivos: Determinar la distribución espacio-temporal de los nichos ambientales y evaluar si las áreas protegidas de la base de Datos Mundial de Áreas Protegidas (DMAP) permiten la conservación de estas especies en el escenario actual y futuro. Métodos: Aplicamos diferentes algoritmos para predecir la distribución y superposición espacio-temporal de nichos ambientales de L. latinasus y P. cuqui dentro de América del Sur en el último máximo glacial (UGM), Holoceno medio, actual y futuro. Evaluamos el estado de conservación de ambas especies con las unidades de conservación de la DMAP. Resultados: Todos los algoritmos aplicados mostraron un alto rendimiento para ambas especies (TSS = 0.87, AUC = 0.95). Las predicciones de L. latinasus mostraron amplios nichos ambientales desde LGM hasta el escenario actual (49 % de nichos estables, 37 % de nichos ganados y 13 % de nichos perdidos), sugiriendo fidelidad histórica por regiones climático-ambientales estables. En la transición actual-futura L. latinasus incrementaría la cantidad de nichos estables (70 %) y perdidos (20 %), sugiriendo fidelidad por regiones de tierras bajas y la posible tendencia hacia el microendemismo. P. cuqui pierde nichos ambientales desde el LGM al escenario actual (25 %) y en la transición actual-futura (63 %), incrementando la simpatría ambiental entre ambas especies; 31 % de superposición espacial en el escenario actual y 70 % en el futuro. Conclusión: Los eventos de sequía extrema y las variaciones de precipitaciones, derivados del cambio climático, sugieren la pérdida de nichos ambientales para estas especies, actualmente no se encuentran amenazadas, pero no están adecuadamente protegidas por las unidades de conservación. La pérdida de nichos ambientales aumenta la simpatría espacial que representa un nuevo desafío para estos anuros y la conservación de sus poblaciones.

Soil greenhouse gas fluxes partially reduce the net gains in carbon sequestration in mangroves of the Brazilian Amazon.

There is interest in assessing the potential climate mitigation benefit of coastal wetlands based on the balance between their greenhouse gas (GHG) emissions and carbon sequestration. Here we investigated soil GHG fluxes (CO2 and CH4) on mangroves of the Brazilian Amazon coast, and across common land use impacts including shrimp farms and a pasture. We found greater methane fluxes near the Amazon River mouth (1439 to 3312 µg C m-2 h-1), which on average are equivalent to 37% of mangrove C sequestration in the region. Soil CO2 fluxes were predominant in mangrove forests to the East of the Amazon Delta. Land use change shifted mangroves from C sinks (mean sequestration of 12.2 ± 1.4 Mg CO2e ha-1 yr-1) to net GHG sources (mean loss of 8.0 ± 3.3 Mg CO2e ha-1 yr-1). Our data suggests that mangrove forests in the Amazon can aid decreasing the net annual emissions in the Brazilian forest sector in 9.7 ± 0.8 Tg CO2e yr-1 through forest conservation and avoided deforestation.

Health conditions in land transport workers and climate change. Exploratory systematic review.

A systematic exploratory review was carried out to describe the influence of climate change on the health conditions of land transport drivers, both physical and mental. Additionally, actions for the prevention of these complications are described. For the review, several databases, such as Science Direct, MEDLINE, Springer, PubMed, Redalyc, EBSCO, SciELO, and Scopus, were examined. There was the need to extend the search timeframe from 5 years to 10 years. The studies found consisted mainly of review articles, showing an emphasis on public health and a high frequency of possible physical effects on the cardiovascular and respiratory systems. At the mental level, the presence of cases of anxiety, depression and stress were mentioned. As for alternatives for the prevention of these effects, the importance of creating public policies for health promotion and disease prevention was highlighted. It is important to increase scientific production in the field of occupational safety and health and applied studies.

Declines in coastal macrozooplankton communities within a recent climate and ocean tipping point in the Tropical South Atlantic.

This study investigated whether variations in climate and ocean drivers on global, regional, and local scales affected macrozooplankton communities in a coastal protected area in Tamandaré Bay (northeastern Brazil). For this purpose, bimonthly field campaigns were carried out from June 2013 to August 2019. A significant tipping point (point of change, p < 0.001), with an abrupt increase in SST, was detected in the TSA (Tropical South Atlantic) index. This indicates the existence of a climate regime shift in the Tropical South Atlantic during the 2015/16 El Niño (EN) event. Extreme rainfall events were observed in Tamandaré Bay after this EN event, in 2017, 2018, and in 2019 (and more recently, in 2022). This extreme rainfall led to low-salinity events, increased variability in salinity, and significantly lower abundances in the period after the strong EN event, for socioeconomically relevant penaeid shrimp postlarvae and several other zooplankton groups (e.g., copepods, appendicularians, anomuran hermit crab larvae, and chaetognaths). We found a significant relationship between SSTs in the TSA region and penaeid shrimp recruitment in the study area, located leewards of the TSA index area. The decline in shrimp postlarvae and other macrozooplankton may be due to a combination of factors, such as climate and ocean shifts (atmospheric easterly waves disturbances, winds, precipitation, salinity) and possibly increasing marine pollution (related to extreme rainfall events, that convey macro- and microplastics, and pollutants from the continent). Cnidarian medusae and fish eggs were among the few "winners" of this ecosystem regime shift. Changes in climate, ocean, macrozooplankton, and shrimp postlarvae abundance evidence a relevant climate, ocean and ecosystem regime shift in this region with a tipping point during 2015/16 "Godzilla" El Niño. Possible future consequences in the context of persistent warming in the TSA region and the currently ongoing record strength 2023/24 EN event are discussed.

Assessing the relationship between river water pollution and the LULC composition of a basin in the Isthmus of Tehuantepec in Oaxaca, Mexico.

Water pollution originating from land use and land cover (LULC) can disrupt river ecosystems, posing a threat to public health, safety, and socioeconomic sustainability. Although the interactions between terrestrial and aquatic systems have been investigated for decades, the scale at which land use practices, whether in the entire basin or separately in parts, significantly impact water quality still needs to be determined. In this research, we used multitemporal data (field measurements, Sentinel 2 images, and elevation data) to investigate how the LULC composition in the catchment area (CA) of each water pollution measurement station located in the river course of the Los Perros Basin affects water pollution indicators (WPIs). We examined whether the CAs form a sequential runoff aggregation system for certain pollutants from the highest to the lowest part of the basin. Our research applied statistical (correlation, time series analysis, and canonical correspondence analysis) and geo-visual analyses to identify relationships at the CA level between satellite-based LULC composition and WPI concentrations. We observed that pollutants such as nitrogen, phosphorus, coliforms, and water temperature form a sequential runoff aggregation system from the highest to the lowest part of the basin. We concluded that the observed decrease in natural cover and increase in built-up and agricultural cover in the upper CAs of the study basin between the study period (2016 to 2020) are related to elevated WPI values for suspended solids and coliforms, which exceeded the allowed limits on all CAs and measured dates.

Plasticity cannot fully compensate evolutionary differences in heat tolerance across fish species.

Understanding how evolution and phenotypic plasticity contribute to variation in heat tolerance is crucial to predict responses to warming. Here we analyze 272 thermal death time curves of 53 fish species acclimated to different temperatures and quantify their relative contributions. Analyses show that evolution and plasticity account, respectively, for 80.5 % and 12.4 % of the variation in elevation across curves, whereas their slope remained invariant. Evolutionary and plastic adaptive responses differ in magnitude, with heat tolerance increasing 0.54 ºC between species and 0.32 ºC within species for every 1 ºC increase in environmental temperatures. After successfully predicting critical temperatures under ramping conditions to validate these estimates, we show that fish populations can only partly ameliorate the impact of warming waters via thermal acclimation and this deficit in plasticity could increase as the warming accelerates.

Variation in the Diet of Hatchling Morelet's Crocodile (Crocodylus moreletii) in the Wild.

The relationship between diet and behavior is essential to understanding an animal's strategies to obtain food, considering ontogenical changes. In reptiles, there is a relationship between the length of the individual and the size of the prey it consumes. Studies have focused on the ontogenetic changes in reptile diets from hatchling to adult, but only a few studies have focused on the transition from hatchling to juvenile. We aimed to describe and analyze the composition, variation, diversity, and overlap in the diet of hatchling Morelet's crocodiles (Crocodylus moreletii) for three size intervals during the hatchling-juvenile transition. We captured 31 hatchling Morelet's crocodiles in an urbanized lagoon in Tabasco. We performed stomach-flushing to determine the diet. Additionally, we estimated the volume, frequency of occurrence, and relative importance of diet items and analyzed the relationship between prey type and the total length of the individuals. The diversity of the hatchling prey suggests a generalist diet. We observed two items not previously described in the diet of hatchling crocodiles. In addition, we found differences in diet between the initial and final size intervals, as increases in the length of prey appeared that they did not consume when they were hatchlings. Our results contribute new information to the dietary changes that occur during the hatchling-juvenile transition.

Semi-Arid Environmental Conditions and Agronomic Traits Impact on the Grain Quality of Diverse Maize Genotypes.

We assessed the impact of environmental conditions and agronomic traits on maize grain quality parameters. The study was conducted using genotypes with distinct genetic constitutions developed specifically for late sowing in semi-arid environments. We evaluated the agronomic, physical, and chemical characteristics of eight maize open-pollinated varieties, six inbred lines, and three commercial hybrids. The yield of the open-pollinated varieties showed a positive correlation with protein content (r = 0.33), while it exhibited a negative correlation with the carbohydrate percentage (r = -0.36 and -0.42) in conjunction with the inbred lines. The flotation index of the hybrids was influenced primarily by the environmental effect (50.15%), whereas in the inbred lines it was nearly evenly divided between the genotype effect (45.51%) and the environmental effect (43.15%). In the open-pollinated varieties, the genotype effect accounted for 35.09% and the environmental effect for 42.35%. The characteristics of plant structure were associated with grain quality attributes relevant for milling, including hardness and test weight. Inbred lines exhibited significant genotype contributions to grain hardness, protein, and carbohydrate content, distinguishing them from the other two germplasm types. These associations are crucial for specific genotypes and for advancing research and development of cultivars for the food industry.

Unraveling impacts on carbon, water and energy exchange of Pinus plantations in South American temperate ecosystems.

Tree plantations are expanding in southern South America and their effects on ecosystem services, particularly climate regulation, are still not well understood. Here, we used remote sensing techniques and a paired design to analyze ≈33,000 ha of Pinus plantations along a broad geographical and environmental gradient (26-43° South latitude, 54-72° West longitude). Radiation interception, surface temperature, evapotranspiration, and albedo were assessed both in tree plantations stands and in adjacent uncultivated areas. Additionally, the climatic impact of tree plantations was quantified by analyzing changes in atmospheric radiative forcing and its carbon (C) equivalent. Tree plantations intercepted more radiation when replacing steppes, grasslands, and shrublands but not when replacing forests. The control exerted on radiation interception by precipitation decreased in both space and time after tree plantation. Furthermore, evapotranspiration notably increased in tree plantations. The lower albedo of tree plantations compared to uncultivated adjacent areas induces global warming through the biophysical pathway. Thus, the climate benefits of afforestation through C sequestration can be counteracted by 18 to 83 % due to albedo changes. It is necessary to fully consider the biophysical effects and water footprint of tree plantations in public policies that promote them, as well as in international carbon accounting mechanisms.

Weight change and lifestyle modifications implemented during the COVID-19 pandemic lockdown are associated with the development of gastrointestinal symptoms.

INTRODUCTION AND AIMS: Pandemic lockdown measures are a cause of concern, regarding their negative impact on the mental health of individuals. The results of numerous studies have associated the appearance of gastrointestinal symptoms with different psychologic disorders, such as stress, depression, and anxiety, due to gut-brain axis interaction. The aim of the present study was to determine the prevalence of, and factors associated with, gastrointestinal symptom onset related to the COVID-19 pandemic lockdown and various lifestyle modifications. METHODS: An analytic, observational, and cross-sectional study was conducted on an open population that agreed to participate within the time frame of January to May 2021. RESULTS: A total of 298 subjects, 165 of whom were women (55.4%), agreed to participate and the mean patient age was 36.1 ±â€¯12.6 years. There was a significant increase in the frequency of several gastrointestinal symptoms: epigastric burning, early satiety, heartburn, regurgitation, constipation, and diarrhea. Changes in weight and modifications in lifestyle were found to be associated variables. CONCLUSIONS: The results of this study showed a significant increase in a wide variety of gastrointestinal symptoms related to lifestyle changes due to the pandemic lockdown. Weight change, supplement and multivitamin intake, and reduced physical activity were the main associated risk factors. Public healthcare systems should take a multidisciplinary approach into consideration for the care of affected individuals.

Future changes of precipitation types in the Peruvian Andes.

In high-altitude regions, such as the Peruvian Andes, understanding the transformation of precipitation types under climate change is critical to the sustainability of water resources and the survival of glaciers. In this study, we investigate the distribution and types of precipitation on a tropical glacier in the Peruvian Central Andes. We utilized data from an optical-laser disdrometer and compact weather station installed at 4709 m ASL, combined with future climate scenarios from the CMIP6 project, to model potential future changes in precipitation types. Our findings highlight that increasing temperatures could lead to significant reductions in solid-phase precipitation, including snow, graupel and hail, with implications for the mass balance of Andean glaciers. For instance, a 2 °C rise might result in less than 10% of precipitation as solid, in regard to the present day, transforming the hydrological processes of the region. The two future climate scenarios from the CMIP6 project, SSP2-4.5 and SSP5-8.5, offer a broad perspective on potential climate outcomes that could impact precipitation patterns in the Andes. Our study underscores the need to revisit and expand our understanding of high-altitude precipitation in the face of climate change, paving the way for improved water resource management strategies and sustainable glacier preservation efforts in these fragile ecosystems.

The silent invaders: Oropouche and Melao viruses, causes of increased public health risks for the Americas.

The Oropouche virus (OROV) is emerging as a major public health threat worldwide, yet for the Americas, it raises complex challenges that intersect with other existing arboviral threats such as Zika (ZIKV), dengue (DENV) and Chikungunya (CHIKV) viruses. Originating from Trinidad and Tobago in 1955, it has spread across the Amazonian Basin and more recently into the Caribbean (Cuba and Haiti) and Europe, highlighting the importance of air travel in its dissemination. OROV and the less studied Melao virus (MELV), pose significant laboratory diagnostic challenges particularly in regions co-endemic with other arboviral diseases, such as dengue and Zika fever. The effects of climate change, particularly in the Caribbean, may exacerbate the transmission of these viruses by exposing human exposure risk to vectors. Public health systems in the Americas are under strain due to complex clinical management of these infections necessitating enhanced surveillance, clinical vigilance, diagnostics and vector control. Vulnerable populations, including pregnant women, elderly, and young children, are at a heightened risk, which raises concerns about the impact on medical tourism in the region. To mitigate the spread and impact of OROV and MELV, recommendations include increased clinical surveillance, improved laboratory diagnostics, public health communication, and strengthened vector controls. Robust research and capacity building (including training and education) efforts are essential to address knowledge gaps and effectively manage future OROV and MELV outbreaks in the Americas.

Climate hazards in Latin American cities: Understanding the role of the social and built environments and barriers to adaptation action.

Climate hazards threaten the health and wellbeing of people living in urban areas. This study characterized reported climate hazards, adaptation action, and barriers to adaptation in 124 Latin American cities, and associations of climate hazards with urban social and built environment characteristics. We examined cities that responded to a global environmental disclosure system and that were included in the Urban Health in Latin America (SALURBAL) Project database. The cities studied reported a median of three climate hazards. The most reported hazards were storms (61%) water scarcity (57%) extreme temperature (52%) and wildfires (51%). Thirty-eight percent of cities reported four or more distinct types of hazards. City size, density, GDP, and greenness were related to hazard reports, and although most cities reported taking actions to reduce vulnerability to climate change, 23% reported no actions at all. The most frequently reported actions were hazard mapping and modeling (47%) and increasing vegetation or greenspace coverage (45%). Other actions, such as air quality initiatives and urban planning, were much less common (8% and 3%, respectively). In terms of challenges in adapting to climate change, 35% of cities reported no challenges. The most frequently reported challenges were urban environment and development (43%) and living conditions (35%). Access to data, migration, public health, and safety/security were rarely reported as challenges. Our results suggest that climate hazards are recognized, but that adaptation responses are limited and that many important challenges to response action are not fully recognized. This study contributes to understanding of local priorities, ongoing actions, and required support for urban climate vulnerability assessment and adaptation responses. Findings suggest the need for future research documenting local perceptions of climate hazards and comparison with documented climate hazards.

Climate change impacts on dengue transmission areas in Espírito Santo state, Brazil.

Espírito Santo state, in Brazil, is a dengue-endemic region predicted to suffer from an increase in temperature and drought due to climate change, which could affect the areas with active dengue virus transmission. The study objective was modeling climatic factors and climate change effects in zones suitable for dengue virus transmission in Espírito Santo state, Brazil. Data on dengue reports from 2022 were used to determine climatic variables related to spatial distribution. The climate change projections were generated for the 2030s, 2050s, 2070s, and 2090s for three distinct Shared Socioeconomic Pathways: SSP1-2.6, SSP2-4.5 and SSP5-8.5. A maximum entropy algorithm was used to construct the three models and projections, and the results were used to calculate the ensemble mean. Isothermality, the maximum temperature of the warmest month, precipitation of the wettest month, precipitation of the warmest quarter, and annual precipitation impacted the model. Projections indicated a change in areas suitable for dengue virus transmission, varying from -30.44% in the 2070s (SSP1-2.6) to +13.07% in the 2070s (SSP5-8.5) compared to 2022. The coastal regions were consistently suitable in all scenarios. Urbanized and highly populated areas were predicted to persist with active dengue transmission in Espírito Santo state, posing challenges for public health response.
