Phylogenetic associations among six closely related South American felid species were defined by changes in protein-encoding gene loci. We analyzed proteins isolated from skin fibroblasts using two-dimensional electrophoresis and allozymes extracted from blood cells. Genotypes were determined for multiple individuals of ocelot, margay, tigrina, Geoffroy's cat, kodkod, and pampas cat at 548 loci resolved by two-dimensional electrophoresis and 44 allozyme loci. Phenograms were constructed using… 
Phylogenetic reconstruction of the felidae using 16S rRNA and NADH-5 mitochondrial genes
The Felidae family represents a challenge for molecular phylogenetic reconstruction because it consists of 38 living species that evolved from a relatively recent common ancestor (10–15 million years
Patterns of Y and X chromosome DNA sequence divergence during the Felidae radiation.
The mode and tempo of evolution of noncoding sequences of a large intron within Zfy and Zfx, homologous genes located on the felid Y and X chromosomes, are compared.
Resolution of recent radiations within three evolutionary lineages of felidae using mitochondrial restriction fragment length polymorphism variation
Patterns of mitochondrial restriction fragment length polymorphism (RFLP) variation were used to resolve more recent relationships among the species of the Felidae ocelot lineage, domestic cat
Phylogenetic assessment of introns and SINEs within the Y chromosome using the cat family felidae as a species tree.
The data suggest X-degenerate genes within the NRY are singularly powerful markers and offer a valuable patrilineal perspective in species evolution.
Geographic Separation of Domestic and Wild Strains of Toxoplasma gondii in French Guiana Correlates with a Monomorphic Version of Chromosome1a
The studies underscore the marked genetic separation of anthropized and wild strains of T. gondii in French Guiana and provide additional evidence that the presence of Chr1a is associated with successful expansion of widely different lineages within diverse geographic areas.
Evolution of feline immunodeficiency virus in Felidae: implications for human health and wildlife ecology.
Population Polymorphism of Trypanosoma cruzi in Latin America indicated by Proteome analysis and by in vitro amastigote proliferation
The findings suggested that the phenetic distance appearing within the T. cruzi may, to some extent, be associated with the intracellular growth of T.cruzi, one of the characteristic features of growth found in the spe- cies.
Small spotted bodies with multiple specific mitochondrial DNAs: existence of diverse and differentiated tigrina lineages or species (Leopardus spp: Felidae, Mammalia) throughout Latin America
Two sets of mitochondrial (mt) DNA data from tigrinas sampled in Costa Rica, Venezuela, Colombia, Ecuador, Peru, Bolivia, northwestern and northeastern Argentina and southern Brazil revealed the existence of seven different tigrina-like haplogroups, which could represent, at least, 4–6 different tigrate species following the Phylogenetic Species Concept (PSC).
Non-invasive genetic identification of two sympatric sister-species: ocelot (Leopardus pardalis) and margay (L. wiedii) in different biomes
The method presented in here allows for the unequivocal differentiation between non-invasive samples of ocelots and margays, when used in combination with the protocol by Roques et al. (Mol Ecol


The topological concordance of the data sets from one‐ and two‐dimensional electrophoresis supports the usefulness of these procedures for evolutionary inference and provides additional precision to the reconstruction of divergence nodes of this carnivore group.
A molecular phylogeny of the hominoid primates as indicated by two-dimensional protein electrophoresis.
A molecular phylogeny for the hominoid primates was constructed by using genetic distances from a survey of 383 radiolabeled fibroblast polypeptides resolved by two-dimensional electrophoresis (2DE), appearing to resolve the human-chimpanzee-gorilla trichotomy in favor of a more recent association of chimpanzees and humans.
The phylogenetic distances between 34 of the 37 extant species of Felidae were estimated using albumin immunological distances (AID) and the derived topology is highly consistent with the karyological disposition of these species, as well as with the fossil record of this family.
Molecular distance and divergence time in carnivores and primates.
The results suggest that estimates of molecular distance and divergence time are highly correlated and that rates of molecular evolution are not constant; rather, in general they decline with increasing divergence time in a linear fashion.
Quantitative Cladistic Analyses of Chromosomal Banding Data Among Species in Three Orders of Mammals: Hominoid Primates, Felids and Arvicolid Rodents
Over the past two decades a number of technical advances have been made which have improved the resolving power of differential chromosome staining procedures, enabling the identification of homologous elements both within and between species.
Dating the genetic bottleneck of the African cheetah.
Back calculation from the extent of accumulation of DNA diversity based on observed mutation rates for VNTR (variable number of tandem repeats) loci and mitochondrial DNA supports a hypothesis of an ancient Pleistocene bottleneck that rendered the cheetah depauperate in genetic variation for nuclear coding loci but would allow sufficient time for partial reconstitution of more rapidly evolving genomic DNA segments.
Inferences of species phylogeny in relation to segregation of ancient polymorphisms.
Standard formulas of gene frequency change under genetic drift are used to derive the probability of obtaining incorrect phylogenetic information for three species due to segregation of ancient
A Comparative Summary of Genetic Distances in the Vertebrates
For studies in systematic and evolutionary biology, many kinds of molecular data have the unusual distinction of providing “common yardsticks” for quantitatively comparing genetic distances in
Molecular Evolutionary Genetics
Recent developments of statistical methods in molecular phylogenetics are reviewed and it is shown that the mathematical foundations of these methods are not well established, but computer simulations and empirical data indicate that currently used methods produce reasonably good phylogenetic trees when a sufficiently large number of nucleotides or amino acids are used.
Relationships between Gene Trees and Species Trees1
It is well known that a phylogenetic tree (gene tree) constructed from DNA sequences for a genetic locus does not necessarily agree with the tree that represents the actual evolutionary pathway of
