Many classic examples of adaptive radiations take place within fragmented systems such as islands or mountains, but the roles mosaic landscapes and variable gene flow in facilitating species diversification is poorly understood. Here we combine phylogenetic landscape genetic approaches to understand Darwin's finches, a model radiation. We combined sequence data from 14 nuclear introns, mitochondrial markers, microsatellite variation 51 populations all 15 recognized species. Phylogenetic...
The role of disease in regulating populations is controversial, partly owing to the absence good records historic wildlife populations. We examined birds collected Galapagos Islands between 1891 and 1906 that are currently held at California Academy Sciences Zoologisches Staatssammlung Muenchen, including 3973 specimens representing species from two well-studied families endemic passerine birds: finches mockingbirds. Beginning with samples 1899, we observed cutaneous lesions consistent...
Invasive Asian bighead and silver carp (Hypophthalmichthys nobilis H. molitrix) pose a substantial threat to North American aquatic ecosystems. Recently, environmental DNA (eDNA), genetic material shed by organisms into their environment that can be detected non-invasive sampling strategies assays, has gained recognition as tool for tracking the invasion front of these species toward Great Lakes. The goal this study was develop new species-specific conventional PCR (cPCR) quantitative (qPCR)...
Understanding the mechanisms underlying speciation remains a challenge in evolutionary biology. The adaptive radiation of Darwin's finches is prime example species formation, and their study has revealed many important insights into processes. Here, we report striking differences mating signals (songs), morphology genetics between two remnant populations mangrove finch Camarhynchus heliobates, one rarest world. We also show that territorial males exhibited strong discrimination sexual by...
Populations that are connected by immigrants play an important role in evolutionary and conservation biology, yet we have little direct evidence of how such metapopulations change genetically over time. We compared historic (1894–1906) to modern (1988–2006) genetic variation 11 populations warbler finches at 14 microsatellite loci. Although several lines suggest Darwin's may be decline, found the diversity has not generally declined, broad‐scale patterns remained similar Contrary...
Paired throat and cloacal swabs, along with feather samples, from nesting Double-crested Cormorants (Phalacrocorax auritus) at two sites in Illinois, USA, were tested for presence of invasive bigheaded carp (Hypophthalmichthys spp.) DNA. We also used DNA the calamus to determine cormorant sex. Throat swabs cormorants both locations positive silver (H. molitrix), but none bighead nobilis). Hypophthalmichthys was not detected on feathers. There no significant differences among detection...
Invasive Asian bighead and silver carp (Hypophthalmichthys nobilis H. molitrix) pose a substantial threat to North American waterways. Recently, environmental DNA (eDNA), the use of species-specific genetic assays detect particular species in water sample, has gained recognition as tool for tracking invasion front these toward Great Lakes. The goal this study was develop new conventional PCR (cPCR) quantitative (qPCR) markers detection We first generated complete mitochondrial genome...
The Eurycea bislineata complex ("two-lined salamanders") of eastern North America contains six described species, which three have very similar morphologies and relatively broad geographic distributions, more divergent with narrow distributions. Recent molecular phylogenetic analyses found that four the species in contain deep genetic structure, two (E. cirrigera E. wilderae) are paraphyletic mitochondrial nuclear DNA, inferring current taxonomy does not reflect actual boundaries complex....
In an attempt to fill knowledge gaps relating genetic structure in the endangered gray bat (Myotis grisescens), we investigated geographic patterns multilocus microsatellite DNA (msDNA) genotypes and mitochondrial (mtDNA) haplotype frequencies across eight primary hibernacula. Isolation-by-distance (IBD) was absent msDNA data no bottlenecks were detected, with genotypic diversity (A R = 6.52, H o 0.64) overall differentiation (F ST 0.024, P < 0.001) being comparable other Myotis North...
La subespecie del sur de Florida Buteo lineatus extimus es claramente más pálida y pequeña que otras subespecies, se reproduce a un ritmo menor puede ocupar hábitats muy diferentes, como marismas abiertas pastizales con solo árboles dispersos. Evaluamos la diferenciación poblacional entre población B. l. dos poblaciones orientales ambientes suburbanos (Cincinnati) rurales (Hocking Hills) en el Ohio. Con base análisis 11 loci microsatélites, encontramos una genética significativa las (FST =...
