Wetlands are environments of extreme importance due to their high biodiversity and invaluable ecosystem services. Nevertheless, wetlands worldwide are under the increasing threat of the effects of contaminants, which put at risk the biota and the ecosystems.

The Yacare caiman Caiman crocodilus yacare is protected by law in Brazil but is hunted illegally. Until now, few authorities have had access to data that might allow analysis of the effect of hunting. We used measurements from 2978 confiscated hides and 1358 skulls found in hunters' camps between October 1987 and September 1990 to reconstruct the sizes

We evaluated antibodies against Leptospira spp. in both free-living and captive Caiman latirostris from Atlantic Forest, and free-living Caiman yacare from Pantanal, Brazil, by using a microscopic agglutination test. Overall seropositivity was 17%, with rates of 36% in captive C. latirostris (n=4/11) and 18% in free-living C. yacare (n=4/22).

Nesting Ecology of the Paraguayan Caiman (Caiman yacare) in the Brazilian Pantanal
Journal of Herpetology, 1988Only one published study (Crawshaw and Schaller, 1980) has discussed the nesting biology of Caiman yacare. Most nests described in that study were found along the Bento Gomes River, on the border of the Pantanal, a large (100,000 km2) area of seasonal swampland of the upper basin of the Paraguay River.

Ovarian Carcinoma with Skeletal Metastasis in a Yacare Caiman (Caiman yacare)
Journal of Herpetological Medicine and Surgery, 2020Abstract A 39-yr-old intact adult female Yacare caiman (Caiman yacare) presented with hindlimb paresis. Magnetic resonance imaging and computed tomography studies revealed a compressive vertebral mass in the lumbar spine associated with a large left pelvic osseous mass and multiple extensive osteolytic lesions in both the axial and appendicular

Parasitology Research, 2011
Prevalence of Hepatozoon caimani has been reported in 76% of caimans Caiman yacare from the Pantanal region. Culex (Melanoconion) spp. mosquitoes were recently identified as natural vectors of this parasite. However, culicids are not typically eaten by crocodilians, suggesting that the main transmission route is through ingestion of insectivorous ...

Periods of drought have been observed in the Brazilian Pantanal for several decades, typically occurring from May to November. These droughts impact the conservation of thousands of species, including the yacare caiman (Caiman yacare). This study aimed to describe the pathologic and parasitologic findings from postmortem examinations of free-ranging ...

The Pantanal region is the largest floodplain area in the world and of great biological importance due to its unique flora and fauna. This area is continuously undergoing increasing anthropogenic threats, and has also experienced mercury contamination associated with gold mining and other anthropogenic activities.
