Using life history to predict outcomes of conservation translocations of herpetofauna

Animal Conservation, Volume 28, Issue 4, Page 592-606, August 2025.
We collected data on key life history traits for all herpetofauna profiled in the IUCN Global Conservation Translocation Perspectives series to examine how life history can predict outcomes and difficulties of conservation translocations. The relationships we found provide important insights for conservation practitioners that can be used in the ...

Turbinal bones are still one of the last frontiers of the tetrapod skull: hypotheses, challenges and perspectives

Biological Reviews, Volume 99, Issue 6, Page 2304-2337, December 2024.
ABSTRACT Turbinals are bony or cartilaginous structures that are present in the nasal cavity of most tetrapods. They are involved in key functions such as olfaction, heat, and moisture conservation, as well as protection of the respiratory tract. Despite recent studies that challenged long‐standing hypotheses about their physiological and genomic ...

Neuroanatomy and pneumaticity of the extinct Malagasy “horned” crocodile Voay robustus and its implications for crocodylid phylogeny and palaeoecology

The Anatomical Record, Volume 307, Issue 8, Page 2749-2786, August 2024.
Abstract Voay robustus, the extinct Malagasy “horned” crocodile, was originally considered to be the only crocodylian representative in Madagascar during most part of the Holocene. However, Malagasy crocodylian remains have had confused taxonomic attributions and recent studies have underlined that Crocodylus and Voay populations coexisted on the ...

Efecto de la cantidad y frecuencia alimentaria de una dieta experimental sobre la tasa de crecimiento de un ejemplar juvenil de Crocodylus Intermedius, Crocodylia: Crocodylidae. Efecto de la cantidad y frecuencia alimentaria de una dieta experimental sobre la tasa de crecimiento de un ejemplar juvenil de Crocodylus Intermedius, Crocodylia: Crocodylidae

Caldasia, 1991
One diet was tested during eleven months in one young female of Orinoco crocodile (Crocodylus intermedius) with three consecutive phases. Phase I (three months) with a feeding rate from 20% body weight for month its feed every five days; Phase Two (four ...

Genomic and environmental insights and conservation challenges for two hybridizing iconic crocodile species across Mexico: Crocodylus acutus and C. moreletii

Animal Conservation, Volume 27, Issue 3, Page 308-323, June 2024.
Understanding hybridization is key for conservation of wild species, yet it is still a controversial issue in conservation. We discern geographic and temporal patterns of introgression, migration, and demography for Crocodylus acutus, C. moreletii, and their hybrid lineages.

Reconstruction of the pelvic girdle and hindlimb musculature of the early tetanurans Piatnitzkysauridae (Theropoda, Megalosauroidea)

Journal of Anatomy, Volume 244, Issue 4, Page 557-593, April 2024.
Piatnitzkysauridae were Jurassic theropods that represented one of the earliest lineages to have evolved moderate body size. Here, we reconstructed the hindlimb musculature of this clade, allowing a more complete understanding of myological evolution in theropod pelvic appendages. Abstract Piatnitzkysauridae were Jurassic theropods that represented the

Declinación poblacional del Caimán del Orinoco (Crocodylus intermedius) en dos sectores del sistema del Río Cojedes, Venezuela

Ecotropicos, 2012
La sobreexplotación de Crocodylus intermedius entre las décadas de los 20 y 60 del siglo pasado, diezmó las poblaciones a niveles críticos o incluso hasta eliminarlas en algunas localidades y regiones. En la presente investigación, evaluamos la población del Sistema del río Cojedes (SRC), catalogada como la más importante para la conservación de C ...
