Andrea Brenes Soto was born on the 30th May 1972 in San José, Costa Rica. In 1998, she obtained her Licenciate diploma in Agronomic Engineering with emphasis in Animal Science at the University of Costa Rica with greatest distinction. In 2011 she obtained her Master diploma in Agricultural Sciences and Natural Resources with emphasis in Animal Nutrition, also at the University of Costa Rica. In 2014 she was admitted at Ghent University as PhD student, and in 2015 she started working at the Laboratory of Animal Nutrition, Faculty of Veterinary Medicine, of UGent. For 3.5 years, she investigated nutrition in frogs, with emphasis in metabolic pathways and nutrient utilisation. Before her PhD she worked as zoo nutritionist in zoos and rescue centers, as well as a lecturer and researcher at the University of Costa Rica and the National Technical University. Andrea is author of several scientific publications, and has attended as a speaker aproximately 30 conferences. During her PhD, she was awarded by the Comparative Nutrition Society in 2016 and 2018, and by the European Society of Veterinary Comparative Nutrition in 2018 for her research in frog nutrition.

Korte beschrijving

Frog nutrition and metabolism have gained interest since recognition of the worldwide decline of several species, integrated with conservation actions including captive breeding programs as well as assessment of habitat quality. Chapter 1 evaluated how body scores and blood values interact with colouration in free-range tree frogs, male Agalychnis callidryas and Agalychnis annae from Costa Rica. Significant associations were found between body condition and plasma proteins and haematocrit concentrations, as well as between body condition and colour values scored through a chromaticity diagram. Significant differences were found between species, as well as between populations of A. callidryas, suggesting that despite colour variation, species-based biochemical differences also occur on a regional basis. This study provided valuable information regarding underlying factors affecting body condition and colouration in male tree frogs in nature, rendering insights on the dynamics of nutritional physiology in frogs.
