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, ...200116120284
body size of smilodon (mammalia: felidae).the body masses of the three large saber-toothed machairodontines, smilodon gracilis, s. fatalis, and s. populator, were estimated on the basis of 36 osteological variables from the appendicular skeleton of extant felids. a new model is introduced that takes the reliability of the predictor equations into account, since mass estimates are more reliable when computed from multiple variables per bone. at a body mass range of 55-100 kg, s. gracilis was comparable in size to extant jaguars, and s. f ...200516235255
evolutionary analysis of a large mtdna translocation (numt) into the nuclear genome of the panthera genus species.translocation of cymtdna into the nuclear genome, also referred to as numt, has been reported in many species, including several closely related to the domestic cat (felis catus). we describe the recent transposition of 12,536 bp of the 17 kb mitochondrial genome into the nucleus of the common ancestor of the five panthera genus species: tiger, p. tigris; snow leopard, p. uncia; jaguar, p. onca; leopard, p. pardus; and lion, p. leo. this nuclear integration, representing 74% of the mitochondrial ...200616380222
robust segmentation and analysis of dna microarray spots using an adaptative split and merge algorithm.microarray images push to their limits classical analysis methods, since gene spots are often poorly contrasted, ill defined and of irregular shapes. these characteristics hinder a robust quantification of corresponding values for red and green intensities as well as their r/g ratio. new approaches are thus needed to ensure accurate data extraction from these images. herein we present an automatic non-supervised algorithm for a fast and accurate spot data extraction from dna microarrays. the met ...200616423425
the effects of visitor density and intensity on the behavior of two captive jaguars (panthera onca).several researchers have reported significant effects of visitor density and intensity on captive animal behavior. this study determined whether this was the case for 2 captive jaguars housed at the woodland park zoo, seattle, wa. subjects were monitored for changes in behavior as a function of visitor density and intensity. the jaguars were observed for 8 hr per week for 29 weeks--march 31 until october 11, 1998--for a total of 230 hr. continuous frequency sampling was used, and visitor density ...200516436028

dna microsatellite characterization of the jaguar (panthera onca) in colombia.the colombian jaguar population is thought to contain two different subspecies, panthera onca centralis and panthera onca onca. the genetic structure of this population was evaluated using 12 microsatellite loci (n = 62 samples). in addition, 22 jaguar dna samples from guatemala, paraguay, perú, bolivia, venezuela and brazil were analyzed for these microsatellite loci (n = 84 samples). the results of this study indicate six primary themes. first, the levels of gene diversity were very high. seco ...200616755135
isolation of malassezia spp. from cerumen of wild felids.the objective of this study was to determine the presence of different species of the genus malassezia in the healthy external auditory canal of wild felids maintained in captivity. one hundred and thirty-two adult animals (264 samples of cerumen), 77 males (58.3%) and 55 females (41.7%), were studied: large felids (55 animals) - 26 lions (panthera leo), 13 tigers (panthera tigris), 6 leopards (panthera pardus), 6 jaguars (panthera onca), 2 cheetahs (acinonyx jubatus), 2 pumas (puma concolor); s ...200616772235
a theoretical proposal for the synthesis of carbapenems from 4-(2-propynyl)azetidinones promoted by [w(co)5] as an alternative to the ag+-assisted process.the synthesis of carbapenems from 4-(2-propynyl)azetidinones assisted by both ag+ and [w(co)5] was theoretically investigated by using the b3lyp/6-31+g(d)-lanl2dz level, taking into account the effect of solvent by the pb-scrf model implemented in jaguar. according to our results, the silver-assisted cyclization is a concerted process for which the low yield experimentally observed could mainly stem from the alkaline hydrolysis of the beta-lactam ring. this process is very efficiently catalyzed ...200616871499
two-stage turing model for generating pigment patterns on the leopard and the jaguar.based on the results of phylogenetic analysis, which showed that flecks are the primitive pattern of the felid family and all other patterns including rosettes and blotches develop from it, we construct a turing reaction-diffusion model which generates spot patterns initially. starting from this spotted pattern, we successfully generate patterns of adult leopards and jaguars by tuning parameters of the model in the subsequent phase of patterning.200616907134

pigment pattern in jaguar/obelix zebrafish is caused by a kir7.1 mutation: implications for the regulation of melanosome movement.many animals have a variety of pigment patterns, even within a species, and these patterns may be one of the driving forces of speciation. recent molecular genetic studies on zebrafish have revealed that interaction among pigment cells plays a key role in pattern formation, but the mechanism of pattern formation is unclear. the zebrafish jaguar/obelix mutant has broader stripes than wild-type fish. in this mutant, the development of pigment cells is normal but their distribution is altered, maki ...200617121467
risk factors associated with sero-positivity to toxoplasma gondii in captive neotropical felids from brazil.from september 1995 to february 2001, blood samples were collected from 865 neotropical felids belonging to 8 different species. these animals were housed in 86 institutions located in 78 cities of 20 brazilian states. our goal was to identify the risk factors associated with sero-positivity to toxoplasma gondii in captive neotropical felids from brazil. all serum samples were tested by the modified agglutination test (mat), using formalin-fixed whole tachyzoites and mercaptoethanol. for each an ...200717140683
molecular evidence for species-level distinctions in clouded leopards.among the 37 living species of felidae, the clouded leopard (neofelis nebulosa) is generally classified as a monotypic genus basal to the panthera lineage of great cats. this secretive, mid-sized (16-23 kg) carnivore, now severely endangered, is traditionally subdivided into four southeast asian subspecies (figure 1a). we used molecular genetic methods to re-evaluate subspecies partitions and to quantify patterns of population genetic variation among 109 clouded leopards of known geographic orig ...200617141620
the re-emergence of felid camouflage with the decay of predator recognition in deer under relaxed selection.when a previously common predator disappears owing to local extinction, the strong source of natural selection on prey to visually recognize that predator becomes relaxed. at present, we do not know the extent to which recognition of a specific predator is generalized to similar looking predators or how a specific predator-recognition cue, such as coat pattern, degrades under prolonged relaxed selection. using predator models, we show that deer exhibit a more rapid and stronger antipredator resp ...200717148247
the expression pattern and cellular localisation of myosin vi during the drosophila melanogaster life cycle.myosin vi is a motor protein which is necessary for the morphogenesis of epithelial tissues during drosophila development. the spatial and temporal expression of myosin vi was examined by expressing a gfp (green fluorescent protein) tagged myosin vi molecule (pgm), under the control of a myosin vi-gal4 line. pgm was present in tissues that were shown previously to express myosin vi, such as the ovarian follicle epithelium, and the individualization complex; and in other tissues, including the tr ...200717185045
[toxoplasmosis in french guiana. atypical (neo-)tropical features of a cosmopolitan parasitosis].toxoplasmosis, a typical cosmopolitan parasitosis, is a major health problem in french guiana. three factors account for this situation, i.e., (1) severity of toxoplasmosis in patients with hiv infection that is particularly prevalent in the area, (2) high risk of congenital transmission as shown by the steadily increasing prevalence of seropositivity in function of age in most of the guianese population and (3) recent identification of severe primary toxoplasmosis infection in immunocompetent p ...200617201300
