| activity of tabanids (insecta: diptera: tabanidae) attacking the reptiles caiman crocodilus (linn.) (alligatoridae) and eunectes murinus (linn.) (boidae), in the central amazon, brazil. | tabanid females are better known as hematophagous on man and other mammals, and linked to mechanical transmission of parasites. the association between tabanids and reptiles is poorly known, but has been gaining more corroboration through experiments and occasional observation in the tropics. the present study was conducted at a military base (cigs/bi-2), situated 54 km from manaus, amazonas, in a small stream in a clearing (02 degrees 45'33"s; 59 degrees 51'03"w). observations were made monthly ... | 2002 | 11992164 |
| distribution and abundance of four caiman species (crocodylia: alligatoridae) in jaú national park, amazonas, brazil. | jaú national park is a large rain forest reserve that contains small populations of four caiman species. we sampled crocodilian populations during 30 surveys over a period of four years in five study areas. we found the mean abundance of caiman species to be very low (1.0 +/- 0.5 caiman/km of shoreline), independent of habitat type (river, stream or lake) and season. while abundance was almost equal, the species' composition varied in different waterbody and study areas. we analysed the structur ... | 2001 | 12189791 |
