Radiographic evaluation of gastroliths in a group of 49 juvenile saltwater crocodiles (Crocodylus porosus) in the UK

Veterinary Record, EarlyView.
Abstract Background Gastrolith ingestion is a known inherent behaviour in crocodiles. However, the interpretation of coelomic radiographs in crocodilians is challenging due to the limited informative literature in this field. Methods Dorsoventral coelomic radiographs of 49 juvenile saltwater crocodiles (Crocodylus porosus) were acquired twice, with an ...

Many roads to reservoirs? How susceptibility and shedding shape host competence in amphibians

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Host competence—the ability to acquire, harbour and transmit infections—drives pathogen spread and persistence in multi‐host communities. Evaluating species‐specific competence is critical for predicting transmission, particularly for generalist fungal pathogens like ...

Poor biosecurity could lead to disease outbreaks in animal populations. [PDF]

PLoS ONE, 2018
Human-mediated disease outbreaks due to poor biosecurity practices when processing animals in wild populations have been suspected. We tested whether not changing nitrile gloves between processing wood frog (Lithobates sylvaticus) tadpoles and co-housing

The Importance of Environmental Heterogeneity in Evaluating the Conservation Status of Two Frog Species in a Changing Amazonian Interfluve

Animal Conservation, EarlyView.
Identifying the most effective criterion to assess the conservation status of vulnerable species in threatened tropical regions is crucial to evaluate recovery plans. We investigated the influence of environmental heterogeneity on the extent of occurrence (EOO), area of occupied habitat (AOH), and density variation of two Amazonian riparian frog ...

Possible Role of Fish and Frogs as Paratenic Hosts of Dracunculus medinensis, Chad

Emerging Infectious Diseases, 2016
Copepods infected with Dracunculus medinensis larvae collected from infected dogs in Chad were fed to 2 species of fish and tadpoles. Although they readily ingested copepods, neither species of fish, Nile tilapia (Oreochromis niloticus) nor fathead ...

Photo go‐alongs for researching the relations between people and place

Area, EarlyView.
Short Abstract This paper demonstrates the value of photo go‐alongs as a qualitative method for researching the complex relationships between people and place. Three key advantages are discussed. First, photo go‐alongs show how pasts and futures shape the unfolding present. Second, they highlight how biographical and social memories intertwine.

Development of Uncertainty Sensitivity: Early Competence or Protracted Development?

Developmental Science, Volume 29, Issue 2, March 2026.
ABSTRACT The development of uncertainty sensitivity, a critical cognitive ability, presents a challenging paradox: Some evidence points to its emergence in infancy, whereas other evidence indicates much later emergence and protracted development.
