Feeding ecology of the pygmy gecko Coleodactylus natalensis (Squamata: Sphaerodactylidae) in the Brazilian Atlantic Forest

open access: yesZoologia (Curitiba), 2012
We studied the feeding ecology of a population of Coleodactylus natalensis Freire, 1999, an endemic gecko of Atlantic Forest fragments in the state of Rio Grande do Norte, northeastern Brazil.

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment

open access: yesThe Anatomical Record, EarlyView.
Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Zooarchaeological Analysis of an Atoll Assemblage From Central Micronesia

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT There has been a dearth of archaeological research on atolls in the central‐eastern Caroline Islands of Micronesia. This has limited our understanding of pre‐contact subsistence and settlement strategies in these more marginal and remote environments, particularly in regards to zooarchaeological data.

Class Conflict: Diffuse Competition between Mammalian and Reptilian Predators

open access: yesDiversity, 2020
(1) Diffuse competition affects per capita rates of population increase among species that exploit similar resources, and thus can be an important structuring force in ecological communities.

The Case of the Missing Green Iguana Predators: Reviews of Ecological Literature Should Go Beyond Google Scholar

open access: yesThe Bulletin of the Ecological Society of America, EarlyView.
Abstract Knowing about species interactions is essential for ecological research, conservation efforts, resource management, and maintaining healthy ecosystems, but many of these, such as reports of predation, may not always be published in easily located resources—if they are published at all.

Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology

open access: yesBiological Reviews, EarlyView.
ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.
