Climatic Niche Modelling Reveals Limited Phylogenetic Niche Conservatism in New World Crocodylians

Journal of Biogeography, Volume 53, Issue 6, June 2026.
ABSTRACT Aim Phylogenetic niche conservatism, the tendency of closely related species to retain ancestral ecological traits, has gained considerable interest, yet the lack of integration across independent evaluation methods has hindered our understanding of whether niches are conserved or dynamic.

Phylogeographical analysis and phylogenetic inference based on the cytochrome b gene in the genus Caiman (Crocodylia: Alligatoridae) in Central and South America

, 2023
The genus Caiman is one of the most taxonomically conflictive among crocodilians due to different views about the phylogenetic position of Caiman crocodilus, which has four subspecies: Caiman crocodilus crocodilus, Caiman crocodilus fuscus, Caiman ...

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

Palaeontology, 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 ...

Acompanhamento das alterações post-mortem (Glicólise) no músculo do jacaré do pantanal (Caiman crocodilus yacare) [PDF]

Ciência e Tecnologia de Alimentos, 2003
This paper presents a study of glycogen degradation in longissimus dorsi muscle of pantanal alligator. Glycogen concentration and muscle pH measurements were assessed. Glycolysis took about 50 hours to complete. Initial muscle pH value were in the limits of 6.6 and 6.7 and after 36 hours they dropped to 5.5-5.6.

Host species and age‐specific variation on Hepatozoon prevalence and its effect on body condition in two Neotropical crocodiles

Wildlife Biology, Volume 2025, Issue 5, September 2025.
Many populations of species belonging to the order Crocodilia are threatened due to illegal trafficking, indiscriminate hunting, and habitat loss and degradation affecting crocodilian health and parasitic load. Although several studies have revealed that crocodiles, caimans, and alligators are frequently infected by Hepatozoon spp., the results from ...

Perceptions and reality in fisher coexistence with aquatic predators in the Peruvian Amazon

Animal Conservation, Volume 27, Issue 4, Page 566-579, August 2024.
The perceptions and reality of ‘human–wildlife conflict’ are infrequently compared, but this relationship is key to determining how negative outcomes can be mitigated. We trained fishers to complete fishing registers to record damage to nets by six large aquatic piscivores (two caiman, two dolphins, two otters) in Amazonian Peru, and compared these ...

Long‐distance swimming by African lions in Uganda

Ecology and Evolution, Volume 14, Issue 7, July 2024.
We present a visual documentation of long‐distance swimming by African lions in Uganda. This first recorded visual evidence shows lions in the Queen Elizabeth National Park are engaging in risky behavior to find females. Abstract Earth's most imperiled and iconic wildlife are facing tough decisions under increasing human pressure and limited resources.
