Do Active and Passive Antipredator Defences in the Toad Epidalea calamita Differ between Males and Females from Natural Habitats and Agrosystems?

Due to their assumed costs, simultaneous antipredator strategies are expected to face trade-offs, which, however, could be milder in individuals subjected to a more intense predator pressure. In this work, I studied the relationship between locomotion and parotoid glands in the natterjack toad, Epidalea calamita. Specifically, I predicted that individuals with reduced sprint speed would rely more on their chemical defences, having larger and more aposematically coloured parotoid glands. Leer más.

Hemiphyllodactylus zalonicus • The Phylogeny of Hemiphyllodactylus Bleeker, 1860 (Squamata: Gekkonidae) with A Description of A New Species from the Mangin Range, Sagaing Region, northern Myanmar

Phylogenetic analyses of the 49 nominal species of the gekkonid genus Hemiphyllodactylus based on the mitochondrial gene NADH dehydrogenase subunit 2 and its flanking tRNAs resulted in a strongly supported tree composed of a number of regionally localised monophyletic lineages consistent with previous genus-wide analyses.

Acanthocercus ceriacoi • All in All It’s Just Another Branch in The Tree: A New Species of Acanthocercus Fitzinger, 1843 (Squamata: Agamidae), from Angola

Recent integrative taxonomic studies of the agamid genus Acanthocercus Fitzinger, 1843 have shown that Angola harbors three different taxa, all within the Acanthocercus atricollis (Smith, 1849) species complex—A. cyanocephalus (Falk, 1925) in the northeastern parts of the country, A. margaritae Wagner et al. 2021 in the southern regions, and an unnamed species in the central and northwestern parts of Angola.

Growth patterns of Emys orbicularis across a range of aquatic habitats: a long-term study

Emys orbicularis is a semi-aquatic turtle with great longevity being able to reach 50 years. In this study, we estimated the growth rates (in carapace length and body mass) in a population of E. orbicularis from the northeastern Iberian Peninsula over a period of 23 years. Leer más.
