The dark side of the black caiman: Shedding light on species dietary ecology and movement in Agami Pond, French Guiana.

PLoS ONE, 2019
The black caiman is one of the largest neotropical top predators, which means that it could play a structuring role within swamp ecosystems. However, because of the difficulties inherent to studying black caimans, data are sorely lacking on many aspects ...

Early‐Life Manganese Overexposure Activates Microglial Phagocytosis through the YY1/TREM2 Axis Leading to Hippocampal Synaptic Remodeling in Mice

Advanced Science, EarlyView.
Early‐life manganese exposure induces behavioral deficits and aberrant hippocampal synaptic remodeling by enhancing microglial phagocytosis in young adult male mice. Mechanistically, manganese promotes Yin Yang 1 (YY1)/triggering receptor expressed on myeloid cells 2 (TREM2) signaling through enhanced HIF1α‐mediated transcription and suppressed SMURF2 ...

Baseline podocyte‐associated state and persistent cell–matrix transcriptional programs are associated with BALB/c substrain differences in adriamycin nephropathy

Animal Models and Experimental Medicine, EarlyView.
Two closely related BALB/c substrains exhibit different early responses to adriamycin (ADR)‐induced nephropathy. BALB/cByJcl mice showed lower baseline WT1‐positive nuclei counts and NPHS1 immunoreactivity than BALB/cAJcl mice, together with extracellular matrix and integrin programs that were enriched at baseline and persisted at Day 5.

Illegal trade of crocodylians in Colombia: Spatiotemporal dynamics and implications on conservation efforts

Conservation Science and Practice
Crocodylian conservation efforts have encountered significant obstacles from species overhunting to negative local perception. While conservation strategies such as sustainable use have helped the recovery of several crocodylian species around the world,

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

The Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

The Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

Trunk vertebrae osteomyelitis in a spectacled caiman (Caiman crocodilus) [PDF]

, 2015
osteomyelitis is frequently reported in turtles, lizards and snakes and Salmonellae are increasingly reported as the causative organism. however, very little is known of this disease occurring in crocodilians.

Comparison of plasma dipeptidyl peptidase IV activity in two caiman species: Caiman latirostris and Caiman yacare (Crocodylia, Alligatoridae) [PDF]

, 2011
Dipeptidyl peptidase IV (DPPIV) is a well-characterized protease with broad substrate specificity, functionally-related to the activity of many bioactive peptides.
