Universidad de Los Andes
His main research concerns Ecology, Evolutionary biology, Phylogeography, Zoology and Phylogenetic tree. His research in Ecology intersects with topics in Genetic distance, Genetic variation, Isolation by distance and Biological dispersal. His Biological dispersal study integrates concerns from other disciplines, such as Cladogenesis and Pristimantis, Pristimantis myersi, Craugastoridae, Genus.
The concepts of his Evolutionary biology study are interwoven with issues in Effective population size, Genetic structure, Genetic diversity, Molecular clock and Nucleotide diversity. As a part of the same scientific study, Andrew J. Crawford usually deals with the Phylogeography, concentrating on Hylidae and frequently concerns with Clade. His Zoology research includes elements of Taxon, Taricha, Phyletic gradualism and Atavism.
His primary areas of investigation include Ecology, Evolutionary biology, Phylogeography, Zoology and DNA barcoding. His Ecology research incorporates themes from Biological dispersal and Species complex. His Evolutionary biology research is multidisciplinary, incorporating perspectives in Clade, Vicariance, Lineage, Mitochondrial DNA and Genetic divergence.
His work deals with themes such as Hylidae and Coalescent theory, which intersect with Clade. His studies examine the connections between Phylogeography and genetics, as well as such issues in Tree frog, with regards to Taxon. He has included themes like Genetic diversity, Amphibian and Molecular phylogenetics, Phylogenetic tree in his Zoology study.
Andrew J. Crawford spends much of his time researching Evolutionary biology, Ecology, Geography, Gene and Vicariance. His study in Evolutionary biology is interdisciplinary in nature, drawing from both Otophryne, Vertebrate and Genome, Reference genome, Genomics. Andrew J. Crawford integrates several fields in his works, including Ecology and Distribution pattern.
The study incorporates disciplines such as Isolation by distance and Genetic divergence in addition to Vicariance. His Phylogeography study incorporates themes from Zoology, Divergence, Pleistocene, Molecular phylogenetics and Deserts and xeric shrublands. The Zoology study combines topics in areas such as Critically endangered, Endangered species, Species complex, Phylogenetics and Atelopus.
Andrew J. Crawford mainly focuses on Evolutionary biology, Geography, Genomics, Reference genome and Genome. Evolutionary biology and Intragenomic conflict are two areas of study in which Andrew J. Crawford engages in interdisciplinary work. Geography is connected with Phylogeography, Biogeography, Allobates, Ecology and Diversification in his research.
His Phylogeography research is multidisciplinary, relying on both Biological dispersal, Lineage, Pleistocene and Tetrapod. His studies in Genomics integrate themes in fields like Biodiversity conservation, Vertebrate and Identification. His Reference genome research incorporates elements of Chromosome and Haplotype.
