| efficiency of playback for assessing the occurrence of five bird species in brazilian atlantic forest fragments. | playback of bird songs is a useful technique for species detection; however, this method is usually not standardized. we tested playback efficiency for five atlantic forest birds (white-browed warbler basileuterus leucoblepharus, giant antshrike batara cinerea, swallow-tailed manakin chiroxiphia caudata, whiteshouldered fire-eye pyriglena leucoptera and surucua trogon trogon surrucura) for different time of the day, season of the year and species abundance at the morro grande forest reserve (sou ... | 2006 | 17143403 |
| genetic structure in a tropical lek-breeding bird, the blue manakin (chiroxiphia caudata) in the brazilian atlantic forest. | determining the genetic structure of tropical bird populations is important for assessing potential genetic effects of future habitat fragmentation and for testing hypotheses about evolutionary mechanisms promoting diversification. here we used 10 microsatellite dna loci to describe levels of genetic differentiation for five populations of the lek-mating blue manakin (chiroxiphia caudata), sampled along a 414-km transect within the largest remaining continuous tract of the highly endangered atla ... | 2007 | 17927710 |
| searching for bioindicators of forest fragmentation: passerine birds in the atlantic forest of southeastern brazil. | aiming to evaluate the potential of passerine birds as bioindicators of forest fragmentation, we studied the avifauna in the mountain region of the state of rio de janeiro by mist-netting between 2001 and 2005. we sampled six sites, including four small fragments (from 4 to 64 ha) in an agricultural area (teresópolis), one second-growth forest (440 ha - miguel pereira) and a continuous forest (10,600 ha, serra dos orgãos national park - sonp). indicator species analysis and a monte carlo test we ... | 2008 | 18660953 |
| new species and additional data on the chewing louse genus myrsidea (phthiraptera: menoponidae) from wild neotropical passeriformes (aves). | twenty-four species of chewing lice of the genus myrsidea waterston, 1915 (phthiraptera: menoponidae) from neotropical suboscines (passeriformes: formicariidae, furnariidae, pipridae, thamnophilidae, tityridae, tyrannidae) are recorded and discussed. they include: eight new species which are described and illustrated (myrsidea capeki new species ex chiroxiphia caudata; myrsidea leptopogoni new species ex leptopogon superciliaris; myrsidea leucophthalmi new species ex automolus leucophthalmus; my ... | 2018 | 30313568 |
| atlantic bird traits: a data set of bird morphological traits from the atlantic forests of south america. | scientists have long been trying to understand why the neotropical region holds the highest diversity of birds on earth. recently, there has been increased interest in morphological variation between and within species, and in how climate, topography, and anthropogenic pressures may explain and affect phenotypic variation. because morphological data are not always available for many species at the local or regional scale, we are limited in our understanding of intra- and interspecies spatial mor ... | 2019 | 30845354 |
| does scale matter? the influence of three-level spatial scales on forest bird occurrence in a tropical landscape. | consequences of habitat fragmentation for species occurrence are amongst the most important issues in landscape and conservation ecology. empirical and theoretical studies have demonstrated that the total amount of habitat, patch size and connectivity have nonlinear effects on species survival on multiple spatial and temporal scales. therefore, population models need to incorporate multiple scales, which can be extremely valuable to prioritizing conservation efforts in these changing landscapes. ... | 2018 | 29912911 |
| life history and ecology might explain incongruent population structure in two co-distributed montane bird species of the atlantic forest. | comparative phylogeography is a powerful approach to investigate the role of historical and environmental processes in the evolution of biodiversity within a region. in this regard, comparative studies of species with similar habitat preferences are valuable to reduce the confounding influence of habitat association when interpreting phylogeographic patterns. in the atlantic forest of south america, phylogeographic studies of highland and lowland species have shown distinct population structure ... | 2020 | 32771546 |
