Unique Population or Unique Species? Genetic Insights Into the Pygmy Freshwater Crocodiles of Northern Australia

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
There is debate over whether isolated populations of “pygmy” Australian freshwater crocodiles are a unique species. This is a conservation concern as these populations face unique challenges. We found some population differences which support these populations as being ecologically unique and valuable for targeted conservation.

Intangible drivers of tolerance shape human–elephant coexistence in Southwest China

open access: yesPeople and Nature, Volume 8, Issue 8, Page 2763-2780, August 2026.
Abstract Southwest China is home to a small but rapidly expanding population of Asian elephants (Elephas maximus), whose growth has intensified conflicts with people living in shared landscapes. These conflicts result in substantial economic losses and occasional human casualties. This coexistence paradox—where conservation success leads to significant

ANALISIS KONTEN PEMBERITAAN INTERAKSI MANUSIA-SATWA PREDATOR DI INDONESIA

open access: yesJurnal Belantara, 2022
Media reports on human-predator interaction can influence public attitudes and supports toward wildlife conservation. Negative interactions between humans and wildlife in Indonesia are dominated by two predator species: Sumatran tiger (Panthera tigris ...

SOS Cocodrilo Tampico: First‐responder actions to human–crocodile interactions in Northeastern Mexico

open access: yesEcological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Grupo S.O.S. Cocodrilo Tampico (GSOS‐T), a multi‐agency response team in Tampico, Mexico, documented four human–crocodile interactions with Crocodylus moreletii between 2021 and 2022—two fatal, two non‐fatal—revealing that homeless adults face the greatest risk.

Defensin‐DNA Supramolecular Complexes as a New pH‐Sensing Nanomaterial

open access: yesAggregate, Volume 7, Issue 6, June 2026.
Crocodylus porosus β‐defensin 13 (CpoBD13), a host defence peptide from the saltwater crocodile, is discovered to interact with single‐ and double‐stranded DNA to form supramolecular assemblies, termed defensin‐induced spherical complexes (DISCs).

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

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1073-1090, June 2026.
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.

Should the Identification Guidelines for Siamese Crocodiles Be Revised? Differing Post-Occipital Scute Scale Numbers Show Phenotypic Variation Does Not Result from Hybridization with Saltwater Crocodiles

open access: yesBiology, 2023
Populations of Siamese crocodiles (Crocodylus siamensis) have severely declined because of hunting and habitat fragmentation, necessitating a reintroduction plan involving commercial captive-bred populations.

Phylogenetically‐informed estimates of notosuchian (Archosauria, Crocodylomorpha) body size and the challenges of inferring macroevolutionary patterns in extinct groups

open access: yesPalaeontology, Volume 69, Issue 3, 2026.
Abstract Notosuchian crocodylomorphs were predominantly active terrestrial predators, exhibiting a wide range of ecomorphological specializations and body sizes. Given that body size plays an important role in the life history of vertebrates, its accurate estimation for notosuchians is crucial for understanding macroevolutionary and macroecological ...

Morphometric analysis of embryonic development in Alligator mississippiensis, Crocodylus johnstoni and Crocodylus porosus

open access: yesJournal of Zoology, 1990
The size of embryos at various stages of development was determined in three species of crocodilian (Alligator mississippiensis, Crocodylus johnstoni and C. porosus). Various morphometric measurements were taken of embryos throughout development and were described for each stage of development.

ENHYDROSS: A New Mechanistic Model Supports the Trans‐Oceanic Dispersal Capability of Terrestrial Vertebrates

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We introduce ENHYDROSS, a new mechanistic model that uses optimal swimming speed and minimum cost of transport to estimate maximum dispersal distances and durations for vertebrates, enabling assessment of long‐distance oceanic dispersal potential. Applied to a range of extant and extinct animals, the model's estimates generally align with observed data;
