ABSTRACT

Although the COVID-19 lockdowns in 2020 had some environmental benefits, the pandemic's impact on the global economy has also had conservation repercussions, especially in biodiverse nations. Ecuador, which is heavily reliant on petroleum, agricultural exports, and ecotourism, experienced a rise in poverty in response to pandemic shutdowns. In this study, we sought to quantify levels of illegal timber extraction and poaching before and after the start of COVID-19 lockdowns throughout two protected areas (Reserva Jama Coaque [JCR] and Bosque Seco Lalo Loor [BSLL]) in the endangered Pacific Forest of Ecuador. We analyzed chainsaw and gunshot acoustic data recorded from devices installed in the forest canopy from December 2019 to March 2020 and October 2020 to March 2021. Results from generalized linear mixed effects models indicated less chainsaw activity before lockdowns (ßpost.lockdown = 0.568 ± 0.266 SE, p-value = .030), although increased average rainfall also seemed to negatively affect chainsaw activity (ßavg.rainfall = -0.002 ± 0.0006 SE, p-value = .003). Gunshots were too infrequent to conduct statistical models; however, 87% of gunshots were detected during the 'lockdown' period. Observational data collected by rangers from these protected areas also noted an increase in poaching activities beginning mid to late 2020 and persisting into 2021. These results add to the steadily growing literature indicating an increase in environmental crime, particularly in biodiverse nations, catalyzed by COVID-19-related economic hardships. Identifying areas where environmental crime increased during pandemic lockdowns is vital to address both socioeconomic drivers and enforcement deficiencies to prevent further biodiversity loss and disease outbreaks and to promote ecosystem resilience. Our study also demonstrates the utility of passive acoustic monitoring to detect illegal resource extraction patterns, which can inform strategies such as game theory modeling for ranger patrol circuits and placement of real-time acoustic detection technologies to monitor and mitigate environmental crimes.

ABSTRACT

Background: The Tropical Andes is the world's most biodiverse hotspot. This region contains >1,000 amphibian species, more than half of which are endemic. Herein we describe two new glassfrog species (Centrolenidae: Hyalinobatrachium) that we discovered within relatively unexplored and isolated localities of the Ecuadorian Andes. Methods: We employed morphological, acoustic, and molecular methods to test the hypothesis that Hyalinobatrachium mashpi sp. nov and H. nouns sp. nov. are species new to science. Following standard methods, we generated mitochondrial sequences (16S) of 37 individuals in the genus Hyalinobatrachium. We inferred the phylogenetic relationships of the two new species in comparison to all other glassfrogs using Maximum Likelihood. In addition to describing the call of H. mashpi sp. nov., we performed a discriminant analysis of principal components (DAPC) with the advertisement call characteristics of several congeners. Results: Based on an integrative taxonomy approach, we describe two new species. Morphological traits and the inferred phylogeny unambiguously place the new taxa in the genus Hyalinobatrachium. Both species are distinguished from other glassfrogs mainly by their dorsal coloration (i.e., dorsum lime green with small light yellow spots, head usually with interorbital bar) and transparent pericardium (i.e., the heart is visible through the ventral skin). The new species exhibit a high morphological similarity (i.e., cryptic) and occur within relatively close geographical proximity (closest aerial distance = 18.9 km); however, their uncorrected p distance for the mitochondrial gene 16S is 4.6-4.7%, a value that greatly exceeds the genetic distance between closely related species of centrolenid frogs. The DAPC revealed that the advertisement call of H. mashpi sp. nov. is acoustically distinct. Discussion: Our findings are congruent with several previous studies that report a high degree of endemism in the Toisán mountain range, which appears to be isolated from the main Andean cordillera for some amphibian groups. We recommend that both H. mashpi sp. nov. and H. nouns sp. nov. be listed as Endangered, following IUCN criteria. These new species provide another example of cryptic diversity in the Andes-further evidence that the region fosters much more biodiversity than we have the resources to catalog. Threatened by mining and other exploitative industries, these glassfrogs and many other yet-to-be-discovered Andean species highlight the dire need for effective conservation measures-especially in northwestern Ecuador.

ABSTRACT

BACKGROUND: Children with CF have been reported to consume significantly more energy-dense, nutrient-poor foods than controls where there are now concerns of inadequate micronutrient intake. There are no current or comprehensive dietary studies assessing micronutrient intake in CF children. OBJECTIVES: To evaluate micronutrient intake in children with CF compared to recommended dietary intakes (RDIs). METHODS: Dietary intake of 13 micronutrients was measured in CF children aged 2-18 years and age- and sex-matched controls using a validated food frequency questionnaire (The Australian Child and Adolescent Eating Survey). RESULTS: CF children (n = 82) consumed significantly more energy than controls (n = 82) [3142(2531-3822) kcal vs 2216(1660-2941) kcal; p < .001]. Absolute intake in CF children was significantly higher in all micronutrients except vitamin C and folate, however energy-adjusted intake was significantly lower for all micronutrients except vitamin A, sodium, calcium and phosphorous. Energy-adjusted intake in primary school CF children was significantly less than controls in 8/13 micronutrients. Overall, median intakes exceeded the RDIs for all micronutrients however CF children fell short of the RDIs for folate (26.8%), iron (15.9%) and calcium (9.8%). In pre-school, 50% of CF children and 91.7% of controls did not meet the iron RDI. High school CF and control children failed to meet RDIs for 7/13 and 9/13 micronutrients respectively. CONCLUSION: Increased intake of most micronutrients in CF children was largely attributed to higher energy consumption. However, micronutrient density of the diet declined with increasing age, where high school children failed to meet RDIs for most key micronutrients.

ABSTRACT

BACKGROUND: Prescription of a high-energy, high-fat diet is a mainstay of nutrition management in cystic fibrosis (CF). However, families may be relying on energy-dense, nutrient-poor (EDNP) foods rather than nutrient-dense (ND) foods to meet dietary targets. We aimed to evaluate the relative contribution of EDNP and ND foods to the usual diets of children with CF and identify sociodemographic factors associated with higher EDNP intakes. METHODS: This is a cross-sectional comparison of children with CF aged 2-18 years and age- and gender-matched controls. Dietary intake was assessed using the Australian Child and Adolescent Eating Survey (ACAES) food frequency questionnaire. RESULTS: Children with CF (n = 80: 37 males; mean age 9.3 years) consumed significantly more EDNP foods than controls (mean age 9.8 years) in terms of both total energy (median [IQR]: 1301 kcal/day (843-1860) vs. 686 kcal/day (480-1032); p < 0.0001), and as a proportion of energy intake (median [IQR]: 44% (34-51) vs. 31% (24-43); p < 0.0001). Although children with CF met their estimated energy requirements (median [IQR]: 158% (124-187) vs. 112% (90-137); p < 0.0001) and their diets were high in fat (median [IQR]: 38% (35-41) vs. 34% (32-36); p < 0.0001), this was largely attributable to EDNP foods. High EDNP intakes (≥10 serves/day) were associated with socioeconomic disadvantage (p = 0.01) and rural residential location (p = 0.03). DISCUSSION: The energy- and fat-dense CF diet is primarily achieved by overconsumption of EDNP foods, rather than ND sources. This dietary pattern may not be optimal for the future health of children with CF, who are now expected to survive well into adulthood.

ABSTRACT

OBJECTIVE: This study investigated the nature and extent of unhealthy food, beverage, alcohol and gambling sponsors of children's sport development programs. METHODS: Websites of junior development sport programs (n=56) associated with sporting organisations that received funding from the Australian Sporting Commission were analysed. Sponsors were considered unhealthy if they were alcohol or gambling companies or sold food and/or beverages that failed independent nutrition criteria. The websites of the sport development programs were also analysed for types of promotion. RESULTS: There were 246 sponsors identified. Eleven (4.5%) sponsors were food, beverage, alcohol or gambling companies of which 10 (91%) were unhealthy. Surf Lifesaving (n=4) and athletics (n=3) websites had the highest number of unhealthy sponsors. Promotions associated with unhealthy sponsorship included logo placement on homepages (100%), naming rights (31%), logo on sport uniforms (27%) and branded participant packs (31%). CONCLUSIONS: The majority of food and beverage company sponsors in sport development programs are companies associated with unhealthy products. Two websites hosting junior development program information included an alcohol company sponsor and a gambling company sponsor. IMPLICATIONS: Unhealthy product sponsorship of children's sport should be addressed as part of a comprehensive regulation designed to reduce exposure to marketing of unhealthy foods.
