“…We excluded studies that administered exogenous hormones to investigate the time course of fGC metabolite excretion because they did not provide information on circadian patterns required for this analysis. For each species, we compiled data on log 10 adult body mass (De Magalhães & Costa, 2009; Duque, 2012; Jones et al, 2009), activity pattern (cathemeral, nocturnal, diurnal; Feierabend & Kielland, 2014; Jones et al, 2009), and main dietary category. We used the categories carnivory, omnivory, herbivory from the PanTHERIA database (Jones et al, 2009), with the exception of Alouatta seniculus and Gorilla gorilla , for which we used additional sources (Anapol & Lee, 1994; Julliot & Sabatier, 1993; Rogers et al, 2004; Rosenberger et al, 2011).…”

Measuring glucocorticoids is one of the most reliable and widely used techniques to monitor stress responses, however invasive techniques to collect plasma samples may not be applicable for wild populations. Monitoring excreted glucocorticoids is an effective noninvasive technique that researchers have used increasingly over the past two decades, and it has allowed the investigation of glucocorticoids in a variety of species with a range of activity patterns. Many species exhibit predictable circadian patterns of glucocorticoid secretion in accordance with their daily activity pattern. There remains a gap in our understanding of how excreted glucocorticoid metabolites vary throughout the day and across species, despite the utility of this information when developing sampling protocols and analyzing data. We investigated circadian patterns of glucocorticoid excretion in a cathemeral primate species, Eulemur rubriventer (red-bellied lemur), in Ranomafana National Park, Madagascar.We collected fecal samples from 10 individuals throughout the day and analyzed fecal glucocorticoid levels across three time points (Early, Midday, and Late), and again across two time points (Morning and Afternoon). We also investigated whether activity pattern, sex (as a control variable), and other traits associated with gut passage rate (diet, body mass) could help predict the presence and timing of circadian patterns of fecal glucocorticoid metabolites across mammal species. We found that fecal glucocorticoid metabolite levels in E. rubriventer fluctuate throughout the day, with lowest levels in the morning and peak levels in the afternoon. None of the variables that we tested predicted whether daily fecal glucocorticoid metabolites changed significantly throughout the day, nor when levels were likely to peak, across species. We stress the importance of controlling for sampling time and reporting these results as standard practice in studies of fecal glucocorticoid metabolites.

El PNN Selva de Florencia, en los Andes centrales de Colombia, es reservorio de una amplia biodiversidad entre ellas cinco especies de primates. A pesar de ser un área protegida, en su interior existen procesos de transformación antrópica, que influyen directamente en sus ecosistemas. Actualmente, no se cuenta con modelos cuantitativos que nos permitan estimar el efecto de esas transformaciones sobre las poblaciones de primates. Evaluamos la proporción de área usada (ψ), como estimativo de la abundancia de los primates Ateles hybridus, Alouatta seniculus y Cebus versicolor. Se realizaron muestreos en 31 cuadrantes de 1 km2 seleccionados al azar, donde se evaluó: i) presencia de primates; ii) presencia de humanos; así como, el porcentaje de iii) cultivos; iv) pastos; y v) cobertura natural, a partir un mapa de coberturas Corine Land Cover adaptado para Colombia a una escala 1:25 000. Los datos fueron analizados bajo abordaje bayesiano. Para A. hybridus se encontró un ψ de 0,16 y una probabilidad de detección de 0,14, disminuyendo el uso de área en bosques. Para A. seniculus, la ψ fue 0,83 y la probabilidad de detección de 0,14 disminuyendo el uso de área en cultivos. Para C. versicolor se estimó una ψ de 0,36 y una probabilidad de detección de 0,08, disminuyendo el uso de área en presencia de humanos. Los datos aquí presentados son un insumo para el diseño e implementación de un monitoreo efectivo en esta área protegida.
