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

The 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

Novel Non-Invasive Biomonitoring Using Avian Faecal Sacs Reveals Dependence of Pesticide Exposure on Field Distance

Toxics
Pesticides remain among the most significant threats to biodiversity and natural ecosystems. Non-invasive methods, such as the analysis of bird faeces, have shown great potential for detecting pesticide exposure.

Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs

The Anatomical Record, EarlyView.
Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...

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

The 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

Home ranges and hatching success of threatened Eurasian curlew in north-eastern Europe relates to habitat type: Natural vs. agricultural landscapes

Global Ecology and Conservation
Farmland birds are among the most threatened species in Europe, largely as a result of the intensification of agriculture leading to widespread biodiversity losses.

Some food sources of the Zitting Cisticola (Cisticola juncidis) in Malta [PDF]

, 2012
The Zitting Cisticola, Cisticola juncidis (Rafinesque, 1810) is a small insectivorous bird which started breeding in Malta some 40 years ago and is now one of the most diffused species of warblers in the Maltese Islands (Fenech, 2010).

The 9+ month marathon: How pregnancy may have shaped human endurance capacities

The Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in
