| targeted reforestation could reverse declines in connectivity for understory birds in a tropical habitat corridor. | re-establishing connectivity between protected areas isolated by habitat clearing is a key conservation goal in the humid tropics. in northeastern costa rica, payments for environmental services (pes) and a government ban on deforestation have subsidized forest protection and reforestation in the san juan-la selva biological corridor (sjlsbc), resulting in a decline in mature forest loss and the expansion of tree plantations. we use field studies and graph models to assess how conservation effor ... | 2016 | 27755750 |
| asymmetric response of costa rican white-breasted wood-wrens (henicorhina leucosticta) to vocalizations from allopatric populations. | divergence in song between allopatric populations can contribute to premating reproductive isolation in territorial birds. song divergence is typically measured by quantifying divergence in vocal traits using audio recordings, but field playback experiments provide a more direct way to behaviorally measure song divergence between allopatric populations. the white-breasted wood-wren (henicorhina leucosticta; hereafter "wbww") is an abundant neotropical species with four mitochondrial clades (in c ... | 2015 | 26671001 |
| extreme sequence divergence between mitochondrial genomes of two subspecies of white-breasted wood-wren (henicorhina leucosticta, cabanis, 1847) from western and central panamá. | prior studies of mitochondrial variation in white-breasted wood-wrens (henicorhina leucosticta) have suggested that populations in south american and mesoamerica might represent multiple species. here we report the complete mitochondrial genomes from two individuals of h. leucosticta, representing the panamanian subspecies pittieri and alexandri. the two sequences were 16,721 and 16,726 base pairs in size with both genomes comprised of the usual 22 trna genes, 2 rrna genes, 13 protein-coding gen ... | 2016 | 24938093 |
