Genomic footprints of (pre) colonialism: Population declines in urban and forest túngara frogs coincident with historical human activity

open access: yesMolecular Ecology, Volume 33, Issue 4, February 2024.
Abstract Urbanisation is rapidly altering ecosystems, leading to profound biodiversity loss. To mitigate these effects, we need a better understanding of how urbanisation impacts dispersal and reproduction. Two contrasting population demographic models have been proposed that predict that urbanisation either promotes (facilitation model) or constrains (

FAMILY LEPTODACTYLIDAE Werner 1896, 357 (2 subfamilies, 2 genera, 5 species, 1 endemic species) SUBFAMILY LEIUPERINAE Bonaparte 1850, 3 (1 genus, 1 species). The 1850 Bonaparte publication used the spelling Leiuperina, but a similarly titled paper (Bonaparte 1852, 478) used the spelling Leinperina for a group of “Engystomidae.” Pyron & Wiens (2011) is ...

Population genetics of the Chilean frog Batrachyla Leptopus (Leptodactylidae) [PDF]

open access: yesGenetics and Molecular Biology, 2000
Electrophoretic variation of proteins encoded by 14 loci was analyzed in eight (five continental and three insular) populations of the Chilean leptodactylid frog Batrachyla leptopus. The overall proportion of polymorphic loci was estimated to be 18.7% and the average number of alleles per locus, 1.2, while observed and expected heterozygosities were 1 ...

Description and shaping factors of diet and feeding ecology of neotropical tadpoles: A case study and a comprehensive review

open access: yesAustral Ecology, Volume 49, Issue 1, January 2024.
We performed a systematic review on the available literature on in situ studies of neotropical tadpole diets focusing on diet composition and its sources of variation. Such studies approached in just a few instances the effects of seasonality, developmental stage and food selectivity on diet composition, but the available data indicate none of these ...
