The dorsal column nucleus in a reptile, Caiman crocodilus.
The dorsal column nucleus of Caiman crocodilus was identified by using standard orthograde techniques to trace the degeneration that resulted from dorsal rhizotomies in brachial and lumbar regions. Although the dorsal column nucleus was difficult to locate in Nissl and fiber preparations, it was easily identified in histochemical material because it stained intensely with succinate dehydrogenas...
متن کاملGrowth of Caiman crocodilus yacare in the Brazilian Pantanal
We studied growth of the caiman, Caiman crocodilus yacare, in the Brazilian Pantanal for 27 years between 1987 and 2013.We recaptured 647 of 7769 C. c. yacare initially marked in an area of 50 km(2), in two ranches. We were able to determine size at age accurately for 24 male and17 female caimans that had been marked at hatching or less than 1 year old, and recaptured over periods of 5 to 24 ye...
متن کاملFirst Report of Trypanosoma sp. in Spectacled Caiman (Caiman crocodilus): Morphological and Phylogenetic Relationships
In Crocodylidae family three trypanosomes species were described, T. grayi in African crocodilian and T. cecili and Trypanosoma sp. in Caimans species from Brazil. T. grayi was transmitted by tsetse flies and the vector of Brazilian caimans trypanosomes is unknown. We characterized first Brazilian trypanosome isolated in spectacled caiman (Caiman crocodilus) from Mato Grosso State in Brazil. Mo...
متن کاملEconomic aspects of production of Caiman crocodilus yacare.
The breeding of crocodilians is still a recent activity in Brazil. Its peak was in the 1990's, but it has gaps in its production, as there are no norms for the commercial breeding of these animals in captivity. However, its economic potential is great, and the search for ecological balance and viability of commercial production has become a challenge among farmers of this activity. Therefor, th...
متن کاملTo the editor. Re: Pesticides in blood from spectacled caiman (Caiman crocodilus) downstream of banana plantations in Costa Rica.
Spectacled caiman (Caiman crocodilus) are fish-eating crocodilians that inhabit freshwater habitat in tropical regions of the Americas. To assess the exposure of caiman to pesticides from banana plantations, the authors collected whole blood samples (30 mL) from 14 adult caiman that were captured in the North Atlantic region of Costa Rica. Blood samples were analyzed for 70 legacy- and current-...
