Fully Connected Neural Networkfor the Classification of Calls from Two Species of Glass Frogs

open access: yesRevista Ciencia y Tecnología
This document presents the application of machine learning (ML) for the classification of calls from glass frog species, Hyalinobatrachium fleischmanni (Hf) and Espadarana prosoblepon (Ep) based on audio recordings. For this, a dataset of acoustic data obtained through frequency manipulation (+4 semitones for Hf and -4 semitones for Ep) and the ...

New glass frogs distribution data (Amphibia: Centrolenidae) in eastern Ecuador, with comments on the diversity in the region

open access: yesACI Avances en Ciencias e Ingenierías, 2010
We present new information on the latitudinal and altitudinal distribution of five species of recently-described or poorly-known glassfrogs from eastern Ecuador. We include novel data on its body size and natural history. Information on the diversity and biogeography of the centrolenid frogs of Eastern Ecuador is discussed, finding them associated with

Female oviposition site selection influences hatching success and embryonic development in a Neotropical glass frog

open access: yes
Abstract For oviparous animals, the decision of where to lay eggs is critical, as offspring remain sessile from oviposition through hatching and are thus unable to escape unfavorable conditions. Consequently, females are expected to select oviposition sites that benefit embryo development and survival.
