Spatio-temporal patterns of foraging and feeding behavior of Elachistocleis bicolor (Anura: Microhylidae)

We analyzed spatio-temporal patterns and behavior of the foraging activity of the myrmecophagous frog Elachistocleis bicolor. We delimit ten 1m2 plots and recorded the number of frogs, distance between individuals and foraging behavior at half-hour intervals, during nine days. Using a generalized li...

description We analyzed spatio-temporal patterns and behavior of the foraging activity of the myrmecophagous frog Elachistocleis bicolor. We delimit ten 1m2 plots and recorded the number of frogs, distance between individuals and foraging behavior at half-hour intervals, during nine days. Using a generalized linear mixed model, we evaluated the maximum, minimum, and average daily temperature, microhabitat temperature, relative humidity, atmospheric pressure, the number of days since the last rain and last 48 hours accumulated rainfall as explanatory variables of frogs’ activity. The variables that best explained frogs’ activity were: mean atmospheric pressure, number of days since last rain and accumulated rainfall. Frogs showed an aggregated distribution pattern when foraging (Morisita standardized index= 0.501). The average distance between frogs was 47.53±25.28 mm. Frogs displayed a combined (active-passive) foraging strategy, actively searching ant trails, digging with their heads on trails running under the mulch, and them passively preying on ants as they pass through. Results showed that the E. bicolor foraging activity followed a circadian cycle that is regulated by several climatic variables, and that these frogs aggregated when foraging for ants.

Delimitamos diez cuadrantes de 1 m2 en los que registramos el número de ranas, distancia entre individuos y comportamiento a intervalos de media hora durante nueve días. Utilizando modelos lineales mixtos generalizados evaluamos el poder explicativo de las variables: temperaturas diarias máximas, mínimas y medias, temperatura de microhábitat, humedad relativa, presión atmosférica, días transcurridos desde la última lluvia y pluviosidad acumulada en las últimas 48 horas, sobre la actividad de las ranas. Las variables que mejor explicaron la actividad de las ranas fueron: presión atmosférica media, días desde la última lluvia y pluviosidad acumulada. Las ranas mostraron un patrón de distribución agregado durante el forrajeo (índice estandarizado de Morisita = 0,501). La distancia media entre ranas fue 47,53±25,28 mm. Las ranas exhibieron un comportamiento de forrajeo mixto (activo-pasivo), buscando activamente los caminos de hormigas y cavando con la cabeza en los sitios donde los caminos de hormigas discurrían bajo el mantillo, para luego depredar pasivamente sobre las hormigas que pasaban. Los resultados muestran que E. bicolor posee una actividad de forrajeo que sigue un ciclo circadiano regulado por varias variables climáticas y que estas ranas se agrupan durante la alimentación.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Instituto de Ciencias Naturaleshttps://revistas.unal.edu.co/index.php/cal/article/view/63397Universidad Nacional de Colombia Revistas electrónicas UN CaldasiaCaldasiaLópez, Javier Alejandro and Antoniazzi, Carolina Elisabet and Lorenzón, Rodrigo and Ghirardi, Romina (2017) Spatio-temporal patterns of foraging and feeding behavior of Elachistocleis bicolor (Anura: Microhylidae).
