Endocranial anatomy of the earliest Cretaceous European neosuchian crocodyliform Pholidosaurus purbeckensis provides new evidence for the ecological evolution of Pholidosauridae

open access: yesJournal of Anatomy, EarlyView.
We present new insights into the internal cranial anatomy of the neosuchian crocodyliform Pholidosaurus purbeckensis, based on CT‐scan data of material from the lowermost Cretaceous Purbeck Limestone Group, southern UK. From the study of the endocast, we obtained new information on the phylogeny and the ecological evolution of the Family ...

Negative results for anti-Leptospira sp. agglutinins in free-living Iguanas (Iguana iguana) from the Amazon region of Brazil

open access: yesCiência Rural, 2018
: Although, serological studies for leptospirosis in iguanas have already been performed, there is no report in the Amazon region. Therefore, the present study aimed to investigate the presence of anti-Leptospira sp.

The impact of urbanisation on social behaviour: a comprehensive review

open access: yesBiological Reviews, Volume 101, Issue 2, Page 1003-1035, April 2026.
ABSTRACT Urbanisation is a key driver of global environmental change and presents animals with novel stressors and challenges. It can fundamentally influence social behaviour and has the potential to reshape within‐ and between‐species social interactions. Given the role of social behaviour in reproductive fitness and survival, understanding how social

First known trace fossil of a nesting iguana (Pleistocene), The Bahamas.

open access: yesPLoS ONE, 2020
Most species of modern iguanas (Iguania, Iguanidae) dig burrows for dwelling and nesting, yet neither type of burrow has been interpreted as trace fossils in the geologic record.

Not just ‘super‐predators': human behaviour shapes wildlife behavioural responses across avoidance, tolerance and attraction

open access: yesOikos, Volume 2026, Issue 3, March 2026.
Humans are thought to have a disproportionately negative impact on wildlife and are viewed by some as the ultimate ‘super predator'. This view implies that wild animals perceive humans primarily as predators. However, a growing body of evidence shows that wildlife can have remarkable tolerance for, or even attraction to, humans.

A 50‐year perspective on the use and potential of artiodactyl calcanei in bone adaptation studies

open access: yesBiological Reviews, Volume 101, Issue 1, Page 437-485, February 2026.
ABSTRACT Sheep and deer calcanei are important models for studying cortical (compact) and trabecular (cancellous) bone adaptation because they are amenable to direct strain measurement (due to lack of surrounding muscles), experience relatively simple/unidirectional bending, exhibit osteon remodelling, and have the most pronounced regional variations ...

Tooth–bone attachment tissue is produced by cells with a mixture of odontoblastic and osteoblastic features in reptiles

open access: yesJournal of Anatomy, Volume 248, Issue 2, Page 251-268, February 2026.
Tooth attachment in vertebrates ranges from ligament‐based anchorage in mammals to direct fusion in many reptiles. In the veiled chameleon, we identified a transient cell population—termed ankyloblasts—at the tooth‐bone interface. These cells exhibit both odontoblast‐ and osteoblast‐like features.
