| phylogeography, population history and conservation genetics of jaguars (panthera onca, mammalia, felidae). | the jaguar (panthera onca), the largest felid in the american continent, is currently threatened by habitat loss, fragmentation and human persecution. we have investigated the genetic diversity, population structure and demographic history of jaguars across their geographical range by analysing 715 base pairs of the mitochondrial dna (mtdna) control region and 29 microsatellite loci in approximately 40 individuals sampled from mexico to southern brazil. jaguars display low to moderate levels of ... | 2001 | 11251788 |
| seroprevalence of toxoplasma gondii in captive neotropical felids from brazil. | seroprevalence of toxoplasma gondii was determined in 865 captive neotropical felids from 20 states from brazil, sampled from september 1995 to april 1997. sera were tested by the modified agglutination test (mat) using formalin-fixed whole tachyzoites and mercaptoethanol. antibodies (mat> or =1:20) to t. gondii were found in 472 of 865 (54.6%) cats: in 45 of 99 (45.9%) jaguarundis (herpailurus yagouaroundi), in 97 of 168 (57.7%) ocelots (leopardus pardalis), in 68 of 131 (51.9%) oncillas (l. ti ... | 2001 | 11777601 |
| structure and patterns of sequence variation in the mitochondrial dna control region of the great cats. | mitochondrial dna control region structure and variation were determined in the five species of the genus panthera. comparative analyses revealed two hypervariable segments, a central conserved region, and the occurrence of size and sequence heteroplasmy. as observed in the domestic cat, but not commonly seen in other animals, two repetitive sequence arrays (rs-2 with an 80-bp motif and rs-3 with a 6-10-bp motif) were identified. the 3' ends of rs-2 and rs-3 were highly conserved among species, ... | 2001 | 16120284 |
| comparative analyses of semen and endocrine characteristics of free-living versus captive jaguars (panthera onca). | semen and blood samples were obtained from free-living (n = 6) and captive (n = 8) jaguars (panthera onca) to compare reproductive characteristics between the two populations. semen samples were analysed for volume (ml), percentage of motile spermatozoa, rate of forward progression (0-5), concentration (10(6) ml(-1)), total sperm count (10(6)) and sperm morphology. serum testosterone concentration was determined by radioimmunoassay. although ejaculate volume was greater in captive jaguars (n = 4 ... | 2001 | 11690535 |
| glucagonoma in a jaguar (panthera onca). | an obese adult jaguar (panthera onca) was euthanized because of progressive lameness. two 3-cm-diameter pancreatic nodules were identified as islet cell tumors, which were positive with immunohistochemical stains for glucagon, neuron-specific enolase, chromogranin a, and synaptophysin. the jaguar did not present clinical evidence of hyperglucagonemia. | 2000 | 11428406 |
| degenerative spinal disease in large felids. | degenerative spinal disorders, including intervertebral disc disease and spondylosis, seldom occur in domestic cats. in contrast, a retrospective study of 13 lions (panthera leo), 16 tigers (panthera tigris), 4 leopards (panthera pardis), 1 snow leopard (panthera uncia), and 3 jaguars (panthera onca) from the knoxville zoo that died or were euthanatized from 1976 to 1996 indicated that degenerative spinal disease is an important problem in large nondomestic felids. the medical record, radiograph ... | 2000 | 10884118 |
| dietary separation of sympatric carnivores identified by molecular analysis of scats. | we studied the diets of four sympatric carnivores in the flooding savannas of western venezuela by analysing predator dna and prey remains in faeces. dna was isolated and a portion of the cytochrome b gene of the mitochondrial genome amplified and sequenced from 20 of 34 scats. species were diagnosed by comparing the resulting sequences to reference sequences generated from the blood of puma (puma concolor), jaguar (panthera onca), ocelot (leopardus pardalus) and crab-eating fox (cerdocyon thous ... | 2000 | 11050553 |
