Seasonal variations and challenges in estimating populations and identifying species of Korean ungulates using drone‐derived thermal orthomosaic maps

Wildlife Biology, EarlyView.
Drones equipped with thermal infrared (TIR) cameras offer significant time and labor savings in estimating wild ungulate populations. However, accurately monitoring forest‐dwelling ungulates remains challenging due to their elusive behavior and complex habitat.

Contrasting properties of predation and scavenging networks governed by megaherbivores in an African savannah

Journal of Animal Ecology, EarlyView.
For the first time, predation and scavenging networks are directly compared within a single ecosystem. Using an 8‐year dataset of African mammals, including megaherbivores, this study reveals distinct structural rules and body mass constraints, providing a scalable framework for studying consumer–resource dynamics and ecosystem function.

The stuffed crocodile of “Castel Nuovo” in Naples (Italy): new insights from ancient DNA and radiocarbon

The European Zoological Journal, 2020
In the present study, a stuffed crocodile displayed for centuries at the “Castel Nuovo” (New Castle) in Naples was radiocarbon dated and examined using ancient DNA analysis. The specimen was classified as Crocodylus niloticus based on its large body size

Herpetofaunal diversity and community structure in the Murchison Falls - Albert Delta Ramsar site, Uganda

European Journal of Ecology, 2020
1. The area of the Murchison Falls-Albert Delta is among the most important for conservation in East Africa due to the high species richness, and the presence of several endemic species of conservation concern. 2. Here, we report a study on the diversity

Fine structure of the dorsal lingual epithelium in Tarentola annularis and Crocodylus niloticus

Folia Morphologica, 2016
The present study examined the morphological features, histological and histochemical aspect of the tongue of two reptilian species, Tarentola annularis (family: Gekkonidae) and Crocodylus niloticus (family: Crocodylidea), with different habitats, feeding patterns and behaviours, by light and scanning electron microscope.

Computed tomography reveals the endocranial anatomy of Crocodylia: Implications for phylogenetic relationships and ecomorphological convergence across Crocodylomorpha

Journal of Anatomy, EarlyView.
The evaluation of the endocranial anatomy of 43 crocodylian species reveals several differences, including variation in the curvature of the encephalic endocast, the size of the endosseous labyrinth and paratympanic sinuses, and the presence of additional snout sinuses.

A review of the conservation status of the Nile crocodile (Crocodylus niloticus Laurenti, 1768) in aquatic systems of Zimbabwe

Global Ecology and Conservation, 2021
Nile crocodile survival is threatened by water pollution, habitat loss, extensive water abstraction for irrigation, domestic use and industrial development and overexploitation of fisheries resources in water systems in Zimbabwe. This review assessed the

Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Comparative endocranial anatomy in the crocodylians Leidyosuchus canadensis and Stangerochampsa mccabei from the upper Cretaceous of Alberta, Canada

Journal of Anatomy, Volume 249, Issue 2, Page 264-291, August 2026.
Leidyosuchus canadensis and Stangerochampsa mccabei share endocranial features such as posterior projection of a neurovascular canal in the maxilla and a paratympanic sinus system most similar to those of small‐bodied and young extant crocodylians, suggesting that these pedomorphic features may reflect the ancestral crocodylian condition.

Environmental DNA and Conventional Sampling Capture Complementary Patterns of Ichthyofaunal Diversity in the Selangor River Estuary, Malaysia

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Mangrove estuaries are a key ecosystem for coastal fishery resources, especially in developing nations such as Malaysia. Using identical sampling points and duration for both eDNA metabarcoding and conventional sampling, fish community analyses highlight shared and unique taxa, variable taxonomic resolution, and the complementarity of eDNA ...
