ABSTRACT

Introduction: Environmental and intrinsic factors such as seawater temperature, salinity, nutrient concentration, upwelling, species, and life history can influence coral outplant survival and growth, and in consequence, the effectiveness of restoration. Thus, it is key to understand how these factors can shape coral outplant performance to ensure the long-term success of a restoration program. Objective: To establish the survival and growth rate of outplanted coral nursery-reared colonies of branching Pocillopora spp. and massive corals Pavona gigantea, Pavona clavus, and Porites lobata in Bahía Culebra, North Pacific of Costa Rica, and to determine whether the site of origin of the coral fragment and the presence of seasonal upwelling affected the growth of Pocillopora outplants. Methods: From September 2020 to September 2021, we monitored the survival, health, and growth of 30 Pocillopora spp. colonies from six donor sites, and 31 fragments of massive species (P. gigantea [n = 18], P. clavus [n = 8], P. lobata [n = 5]) that were outplanted to a degraded reef. We recorded in situ seawater temperature, salinity, and nutrient concentration. Results: By the end of the year, 100 % of the Pocillopora spp. outplants survived. Survival was 71.4 % for P. clavus, 47.5 % for P. gigantea, and 20 % for P. lobata. Coral tissue loss and predation marks were observed at least once in 71 % of massive outplants. Pocillopora spp. colonies increased their initial area in 333.1 %, at a rate of 9.98 ± 1.69 cm yr-1. The site of origin of the outplant influenced growth rate, but not the presence of seasonal upwelling. Massive species fragments grew at a rate of 1.35 ± 0.24 cm yr-1 for P. clavus, 1.48 ± 0.21 cm yr-1 for P. gigantea, and 0.61 cm yr-1 for P. lobata, with no differences among them. Conclusions: Environmental conditions at site level allow for high survival and growth of Pocillopora spp. outplants, previously considered as sensitive to stressors, and point towards acclimation to seasonal upwelling. Although survival of massive species was lower, developing a multi-species approach is key to enhance restoration success.


Introducción: Factores ambientales e intrínsecos como la temperatura del agua, salinidad, concentración de nutrientes, afloramiento, especies e historia de vida pueden influir en la supervivencia y crecimiento de los trasplantes de coral y, en consecuencia, en la eficacia de la restauración. Por ello, entender cómo estos factores pueden moldear el desempeño de los trasplantes es clave para asegurar el éxito de un programa de restauración a largo plazo. Objetivo: Establecer la supervivencia y tasa de crecimiento de los trasplantes de colonias de coral previamente cultivadas en viveros del coral ramificado Pocillopora spp. y las especies de crecimiento masivo Pavona gigantea, Pavona clavus y Porites lobata en Bahía Culebra, Pacífico Norte de Costa Rica, y determinar si el sitio donante de origen del fragmento de coral y la presencia de afloramiento estacional afectó el crecimiento de los trasplantes de Pocillopora. Métodos: De setiembre 2020 a setiembre 2021, se monitoreó la supervivencia, salud y crecimiento de 30 colonias de Pocillopora spp. de seis sitios donantes diferentes y 31 fragmentos de especies masivas (P. gigantea [n = 18], P. clavus [n = 8], P. lobata [n = 5]) que se trasplantaron a un arrecife degradado. Se registró la temperatura del agua, la salinidad y concentración de nutrientes in situ. Resultados: Al final del año, el 100 % de los trasplantes de Pocillopora spp. sobrevivieron. La supervivencia fue de 71.4 % para P. clavus, 47.5 % para P. gigantea y 20 % para P. lobata. Se observaron pérdidas de tejido y marcas de depredación al menos una vez en un 71 % de los trasplantes masivos. Las colonias de Pocillopora spp. aumentaron su área inicial en un 333.1 %, a una tasa de 9.98 ± 1.69 cm año-1. El sitio de origen del trasplante tuvo efecto sobre la tasa de crecimiento, pero no la presencia de afloramiento estacional. Los fragmentos de especies masivas crecieron a tasas de 1.35 ± 0.24 cm año-1 (P. clavus), 1.48 ± cm año-1 (P. gigantea) y 0.61 cm año (P. lobata), sin diferencias entre ellas. Conclusiones: Las condiciones del sitio permiten una alta supervivencia y crecimiento de trasplantes de Pocillopora spp., que previamente habían sido considerados sensibles a factores estresantes, e indican aclimatación a las condiciones locales de afloramiento estacional. Pese a que la supervivencia de las especies masivas fue menor, es esencial desarrollar un enfoque multi-especie para aumentar el éxito de la restauración.

ABSTRACT

@#Introduction: COVID-19 pandemic has impacted the livelihood of Malaysians and gardening activities have contributed positively to the diet quality. This study aimed to determine the factors associated with diet quality among adults in AU2 Keramat, Kuala Lumpur. Methods: The cross-sectional study involved adults aged 18 to 59 via convenience sampling. The socio-demographic, physical activity level and involvement status in gardening were obtained through a questionnaire, while food intake was from a single-day 24-hour diet recall. The diet quality was determined through Malaysian Healthy Eating Index (MHEI) and dietary misreporting was calculated using the Goldberg cut-off method. Results: A total of 117 respondents (65.8% females, 35.2% males) with a mean age of 40.98 were involved in this study. Findings showed that most respondents did not engage in gardening activities (72.6%) and the prevalence of poor diet quality in this study was 89.7%, with a mean score of 44.51. The older respondents (r= 0.20, p= 0.034) and community gardeners (t= -2.63, p= 0.011) had a significantly higher diet quality but not home gardeners (t= 0.12, p= 0.902). The respondents involved in gardening activity also had a significantly higher fruit serving intake, Mann-Whitney U= 1045.00, p= 0.036) and lower total fat intake (t= 2.27, p= 0.025). Conclusion: The diet quality of the respondents remains poor but community gardeners had significantly higher diet quality and fruit intake while lower total fat intake. Interventions need to be developed to address the persistent poor diet quality of adults in the community.

ABSTRACT

Abstract Introduction Vitamin D deficiency is associated with various diseases. Prevalent in Brazil, it can result from inadequate lifestyle habits. Objective To demonstrate that postmenopausal women with vitamin D deficiency have worse quality of health, expressed as worse quality of life, lower levels of physical activity, and worse nutritional profile. Methods Postmenopausal women answered questionnaires about physical activity and quality of life, provided a 24-hour food record, and had serum vitamin D levels measured. Results Among the more active women, those who perform a daily average of one hour of physical activity had vitamin D levels above 20 ng/mL (76.9%), and those, which expose themselves to sunlight, had vitamin D levels above 30 ng/mL (34.6%). Meanwhile the percentages for the women who are less physically active and less exposed to sunlight were 42.2% and 8.9% respectively. Being more active and more exposed to sunlight resulted in a lower fat percentage. Serum vitamin D levels were not correlated with quality of life. Conclusion Walking and gardening increased serum vitamin D levels and decreased the percentage of body fat. The limitations of the study prevented the impact of 25hidroxyvitamin D on the quality of life and nutritional aspects of the women from being evaluated.


Resumo Introdução A deficiência de vitamina D está associada a diversas doenças. Prevalente no Brasil, pode ser consequência de hábitos de vida inadequados. Objetivo Demonstrar que mulheres na pós-menopausa com hipovitaminose D têm pior qualidade de saúde, expressa por piores qualidade de vida, nível de atividade física e perfil nutricional. Métodos Mulheres na pós-menopausa responderam a questionários sobre atividade física, qualidade de vida, registro alimentar de 24 horas, e tiveram os níveis séricos de vitamina D medidos. Resultados Dentre as mulheres mais ativas, as que praticam em média 1 hora de atividade por dia apresentaram níveis de vitamina D superiores a 20 ng/mL (76,9%), e as que se expõem ao sol apresentaram níveis acima de 30 ng/mL (34,6 %). Já as mulheres menos ativas e menos expostas ao sol apresentaram respectivamente 42,2 % e 8,9%. Ser mais ativa e ter maior exposição solar significou ter menor percentual de gordura. O nível sérico de vitamina D não mostrou relação com a qualidade de vida. Conclusão Caminhada e jardinagem aumentam os níveis séricos de vitamina D e diminuem o percentual de gordura corpórea. As limitações do estudo não permitiram avaliar o impacto da 25-hidróxi-vitamina D na qualidade de vida e nos aspectos nutricionais das mulheres.

ABSTRACT

ABSTRACT Objective: Evaluate the effect of planting herb or vegetable seeds and seedlings on the household availability of fruits and vegetables through an intervention study combining various actions (educational practices, home visits, and distribution of seeds and seedlings) for the promotion of fruit and vegetable consumption in multiple settings. Methods: Data from 70 families were analyzed. Using the stratified sampling technique, the participant families were selected from a stratum within a population of 1,743 families living in three low-income communities in the city of Rio de Janeiro, Brazil. Three post-intervention groups were formed and compared: families that did not receive the seeds and seedlings during the intervention; families that received but did not plant the seeds and seedlings; families that received and planted the seeds and seedlings. Results: Among the families that did not grow their own fruits and vegetables before the intervention, those that received and planted the seeds and seedlings achieved an increase in household availability of fruits and vegetables (Δ=+5.8 percentage points) up to three times higher (p<0.05) than that achieved by the families who did not receive the seeds and seedlings (Δ=+1.8 5 percentage points) and those that received but did not plant them (Δ=+2.3 percentage points). As for the families that grew their own fruits and vegetables before the intervention, the comparison between those that did not receive the seeds and seedlings, those that received and planted them, and those that received but did not plant them showed no differences in the household availability of fruits and vegetables. Conclusion: The planting of the seeds and seedlings that they received by the families that did not grow their own fruits and vegetables before the intervention contributed to a significant increase in the household availability of fruits and vegetables.


RESUMO Objetivo: Analisar o efeito do plantio de sementes e mudas de temperos ou hortaliças sobre a disponibilidade domiciliar de frutas e hortaliças no âmbito de um estudo de intervenção. Este combinou diversas ações de promoção do consumo de frutas e hortaliças em múltiplos cenários, como práticas educativas, visitas domiciliárias, distribuição de sementes e mudas de temperos ou hortaliças. Métodos: Foram analisados dados de 70 famílias selecionadas por meio de uma amostra estratificada. Esses dados permitiram inferir sobre o universo de 1.743 famílias que viviam em três comunidades de baixa renda da cidade do Rio de Janeiro. Três grupos definidos a posteriori foram comparados: não receberam sementes e mudas durante a intervenção; receberam mas não plantaram as sementes e mudas; e receberam e plantaram as sementes e mudas. Resultados: Dentre as famílias que não cultivavam frutas e hortaliças antes da intervenção, aquelas que receberam e plantaram sementes e mudas atingiram um aumento na disponibilidade domiciliar de frutas e hortaliças (Δ=+5,8 pontos percentuais) até três vezes maior (p<0,05) do que os experimentados pelas famílias que não receberam sementes e mudas (Δ=+1,8 pontos percentuais) ou que receberam mas não plantaram (Δ=+2,3 pontos percentuais). Dentre as famílias que já possuíam frutas e/ou hortaliças plantadas antes da intervenção, ao comparar os diferentes grupos, não foram encontradas diferenças na disponibilidade domiciliar de frutas e hortaliças. Conclusão: O plantio de sementes e mudas entregues às famílias que não cultivavam frutas e hortaliças antes da intervenção contribuiu para o efetivo aumento da disponibilidade domiciliar de desse tipo de alimento.

ABSTRACT

ResumoA agricultura urbana e periurbana (AUP) vem sendo praticada em diferentes espaços, contribuindo para a melhoria da saúde nas comunidades e ambientes mais saudáveis. Objetivando identificar significados e repercussões da prática da AUP em Unidades Básicas de Saúde (UBS), enquanto uma atividade de Promoção da Saúde (PS), e em que medida sua dimensão terapêutica a caracteriza como uma atividade alinhada às práticas integrativas e complementares, foi realizado um estudo transversal com abordagem qualitativa no município de Embu das Artes, SP. Da análise, emergiram as seguintes categorias: concepção de saúde, resultados na saúde, resgate de práticas e hábitos tradicionais e reorientação dos serviços de saúde. Identificou-se a estreita ligação entre a prática das hortas e as diretrizes e campos de ação da PS como: criação de ambientes saudáveis, reforço da ação comunitária, desenvolvimento de habilidades pessoais, estímulo à autonomia e empoderamento e demandas por reorientação dos serviços. As atividades de horta instituídas nas UBS se mostraram uma estratégia de implementação das práticas integrativas e complementares (PIC). Conclui-se que as atividades de cultivo nas hortas comunitárias mostram-se como práticas promotoras da saúde que integram elementos fundamentais das PIC.


AbstractUrban and peri-urban agriculture (UPA) is being practiced in different settings, contributing to the improvement of health in communities and healthier environments. In order to identify the meanings and implications of the practice of UPA in Primary Healthcare Units (PHU) as an activity of health promotion (HP), and to what extent its therapeutic dimension characterizes it as an activity aligned with complementary and integrative practices (CIP), a qualitative cross-sectional study was performed in Embu das Artes, State of São Paulo. From the analysis, the following main themes arose: health concept, health outcomes, the return to traditional practices and habits and the reorientation of health services. It was possible to identify the close link between the cultivation of vegetable gardens and HP guidelines and fields of action, such as creating healthier environments, boosting community actions, developing personal skills, stimulating autonomy and empowerment and demands for the reorientation of services. The garden activities, set up in PHU areas, proved to be an implementation strategy of CIP. The conclusion reached is that vegetable gardening activities in community gardens are seen to be health promotion practices that integrate key elements of CIP.

ABSTRACT

The reef-building coral Acropora cervicornis was a dominant ecosystem element on the Caribbean reef until the 1980s, when it declined by some 97% due primarily to anthropogenic ecosystem changes and disease. This branching species expanded its colony footprint and achieved local dominance largely through fragmentation and regrowth, thus is suited to nursery culture towards restoration. In this experiment, fragments of Acropora cervicornis of four lineages or genets were followed and measured for growth and health over 12 months in 2006 and 2007 on buoyant drop-loop line nurseries at one shallow and one deep fore-reef site in Montego Bay, Jamaica. Sixty-five of these corals were then out-planted to wild reef sites of similar depth and condition to their respective nurseries and monitored photographically for 11 months through 2007 and 2008. A period of rapid death was seen in the out-planted material at both sites over the first four months, followed by a period of relative stability or recuperation. Hermodice carunculata predation was the primary problem in the shallow fore-reef, and was combined with a banding syndrome at the deeper site. This syndrome was noted in the samples prior to planting, during a one week storage period on the seafloor. Continued slow decline occurred in the subsequent seven months in the shallow fore-reef site; however, regrowth was noted in the deeper site in the remaining material. Including these losses, final total live coral length was more than fourfold greater than the initial wild harvest: a net increase through multi-stage propagative restoration or coral gardening. Returns were noted particularly in the faster-growing genets of the nursery and larger planted corals tended to retain more material at eleven months, suggesting that propagative restoration programmes invest in stronger genets and larger corals. Adaptive management and maintenance gardening of the planted material and reef would likely have greatly improved outcomes.


La especie constructora de arrecifes de coral Acropora cervicornis era un elemento dominante del ecosistema en el arrecife caribeño hasta la década de 1980, cuando disminuyó en un 97% a nivel regional principalmente debido a cambios antropogénicos y por enfermedad. Esta especie de ramificación amplió su huella de colonia para lograr un dominio local a través de la fragmentación y el rebrote, así se adapta al cultivo de vivero para la restauración. En este experimento, fragmentos de Acropora cervicornis de cuatro linajes fueron seguidos y medidos para el crecimiento y la salud durante 12 meses en 2006 y 2007 en viveros en línea tipo “buoyant drop-loop“ en un sitio somero y otro profundo en el arrecife frontal de Bahía Montego, Jamaica. Sesenta y cinco de estos corales fueron plantados en sitios de arrecife silvestre con condiciones y profundidad similar a sus respectivos viveros y monitoreados mediante fotográfias por 11 meses durante el 2007 y 2008. Se observó un período de muerte rápida en el material plantado en ambos sitios durante los primeros cuatro meses, seguidos por un período de relativa estabilidad o recuperación. La depredación de Hermodice carunculata fue el principal problema en el arrecife frontal poco profundo y se combinó con un síndrome de bandas en el sitio más profundo. Este síndrome se observó en las muestras antes de la siembra, durante un período de almacenamiento de una semana en el suelo marino. A continuación ocurrió un lento descenso en los posteriores siete meses en el sitio de arrecife frontal poco profundo; sin embargo, se observó un rebrote en el sitio más profundo con el material restante. Aún incluyendo estas pérdidas, al final la longitud de coral vivo total fue más de cuatro veces que la inicial: un aumento neto a través de varias etapas de restauración propagativa o de jardinería de coral. Los rechazos fueron observados especialmente en el linaje de crecimiento más rápido del vivero y corales plantados más grandes que tienden a retener más material en once meses, lo que sugiere que los programas de restauración propagativo deben invertir en linajes de coral más fuertes y más grandes. Probablemente se obtengan mayores resultados con un manejo adaptativo y mantenimiento de jardinería del material plantado y de arrecife.

ABSTRACT

Discovery Bay is one of nine sites around Jamaica’s coastline, soon to gain the legislative protection of Fish Sanctuary (and Scientific Reserve) status. Cumulative natural and anthropogenic impacts drove the 1980’s coral to algae phase shift. Discovery Bay CARICOMP data (1994 to 2007) showed an increase in coral cover from less than 5% reported in the mid 1980’s to 11.7±0.31% (mean±SE) despite chronically high algal cover (61.4±2.2%) at 9m. Coral cover has been sustained despite low urchin densities (0.99±0.91 urchins m-2), low juvenile coral abundance (2.15±0.19 corals m-2) and coral mortality from repeated bleaching events. Community metrics from the CARICOMP site were compared to an adjacent reef habitat which was found to have higher coral cover (16.36±3.1%), as well as higher urchin (13.7±0.84m-2) and juvenile coral (9.7±1.7m-2) densities. Large branching coral species were absent along the CARICOMP transects and sparse at the nearby shallow reef. Both sites continue to be heavily overfished. Local history records the use of spatially and temporally isolated management strategies which have attempt to rehabilitate various aspects of this area. This unique temporal data set (based on the CARICOMP Methods Manual 2000) provides a baseline for evaluating Government (in)action and is used to justify proposals for ecosystem management which could facilitate phase shift reversal in a coral dominated system. An ecosystem approach that implements several concurrent strategies within and adjacent to the Reserve could accelerate the recovery process. The long term viability and benefit of both old and new marine protected or reserve areas could be enhanced through coral gardening on artificial reef structures with a view to restoring the reefs’ three-dimensional complexity. Such actions could heoretically accelerate phase reversal to coral dominated reefs common in the area prior to the devastating impacts of the 1980s. Rev. Biol. Trop. 58 (Suppl. 3): 63-69.

Discovery Bay es uno de los nueve sitios alrededor de Jamaica, pronta a obtener la protección legislativa como Santuario de Pesca (y Reserva Científica). Los impactos naturales y antropogénicos acumulativos de la década de 1980 condujo a cambio de fase de coral a algas. Los datos CARICOMP de Discovery Bay (1994 a 2007) mostraron un aumento en la cobertura de coral de menos del 5% informada a mediados de 1980 a 11.7±0.31% (media±ES) a pesar la alta cobertura crónica de algas (61.4±2,2%) a 9m de profundidad. La cobertura de coral se ha mantenido a pesar de las densidades bajas de erizo de mar (0.99±0.91 erizos m-2), baja abundancia de juveniles de coral (2.15±0.19 m corales-2) y mortalidad de corales debido a fenómenos de blanqueo repetitivos. Estadísticas de la comunidad del sitio CARICOMP contrasta con un hábitat de arrecife adyacente que tienen mayor obertura de coral (16.36±3.1%), de erizos (13.7±0.84 m-2) y de juveniles de coral (9.7±1.7 m-2). Especies de coral de grandes ramas estaban ausentes de los transectos CARICOMP y eran pocos en los arrecifes poco profundos cercanos. Ambos sitios siguen siendo, en gran medida, objeto de sobrepesca. La historia local registra el uso de estrategias de gestión espacial y temporalmente aisladas que se implementaron en el pasado para intentar rehabilitar a diversos aspectos de esta área degradada. Los datos temporales de CARICOMP establecen una base única base para la evaluación "en" acción del Gobierno y se utiliza para justificar las propuestas de gestión de los ecosistemas que podrían facilitar la reversión de fase a un sistema dominado por corales. Un enfoque de ecosistemas que implementa varias estrategias simultáneas dentro y adyacente a la Reserva podría acelerar el proceso de recuperación. La viabilidad a largo plazo y el beneficio de viejas y nuevas áreas marinas protegidas o reservas podría ser mejorada a través de cultivo de coral en arrecifes artificiales con el fin de restablecer la complejidad tridimensional de los arrecifes coralinos. Tales acciones podrían, teóricamente, acelerar la reversión de fase a coral como era común en el área antes de los impactos devastadores de la década de 1980.
