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 ...

Distribution of populations of broad-snouted caiman (Caiman latirostris, Daudin 1802, Alligatoridae) in the São Francisco River basin, Brazil Distribuição das populações de jacaré-do-papo-amarelo (Caiman latirostris, Daudin 1802, Alligatoridae) na bacia do Rio São Francisco, Brasil

Brazilian Journal of Biology, 2010
We surveyed populations of the broad-snouted caiman, Caiman latirostris, throughout the São Francisco River basin, from Três Marias reservoir, State of Minas Gerais, to the river delta, at the boarder of Sergipe and Alagoas states.

Disruption of the developmental programming of the gonad of the broad snouted caiman (Caiman latirostris) after in ovo exposure to atrazine.

Environmental Science and Pollution Research, 2022
Abstract Environmental exposure to agrochemicals during early stages of development can induce subtle alterations that could permanently affect normal physiology. Previously, we reported that in ovo exposure to atrazine (ATZ) disrupts testicular histoarchitecture in postnatal caimans (Caiman latirostris).

Evaluation of factors associated with predation on Caiman latirostris nests (Crocodylia: Alligatoridae) in Argentina

Phyllomedusa: Journal of Herpetology, 2016
Predation is a major cause of crocodilian egg loss. However, at present, the mechanisms by which predators detect nests is unknown. Previous studies have reported that predators are able to detect prey using both visual and olfactory cues.

Developmental Patterns of Hepatic Peroxisome Proliferator‐Activated Receptor (PPAR) Expression in Xenopus laevis and Response to Pharmaceutical Agonists During Metamorphic Climax

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 10, Page 1191-1204, December 2025.
ABSTRACT Peroxisome proliferator‐activated receptors (PPAR) are master transcriptional regulators that maintain metabolic homeostasis in vertebrates. Amphibians are often exposed to endocrine disrupting compounds (EDCs) that could dysregulate lipid metabolism.

Broad snouted caiman (Caiman latirostris) growth under different rearing densities

Aquaculture, 2008
Abstract The effect of density on growth in body mass (BM) and total length (TL) of Caiman latirostris hatchlings raised in small pens (area 0.36 m2), for 3 months, was investigated. Twelve animals from each of three clutches were randomly distributed (1, 2 or 3 individuals) to two replicates at low rearing density (LRD: 0.12 m2/individual), medium ...
