effects of matrix characteristics and interpatch distance on functional connectivity in fragmented temperate rainforests.	the connectivity of remnant patches of habitat may affect the persistence of species in fragmented landscapes. we evaluated the effects of the structural connectivity of forest patches (i.e., distance between patches) and matrix class (land-cover type) on the functional connectivity of 3 bird species (the white-crested elaenia [elaenia albiceps], the green-backed firecrown hummingbird [sephanoides sephaniodes], and the austral thrush [turdus falklandii]). we measured functional connectivity as t ...	2012	22443129
two new and two redescribed species of anonchotaenia (cestoda: paruterinidae) from south american birds.	morphological examination of novel specimens of paruterinid cestodes from passerine birds from brazil and chile and of museum specimens from paraguay revealed two new species: anonchotaenia prolixa sp. n. from elaenia albiceps chilensis hellmayr from chile, and anonchotaenia vaslata sp. n. from tyrannus melancholicus (vieillot) (type host) and myiodynastes maculatus (statius muller) from paraguay. the generic diagnosis of anonchotaenia conn, 1900 is amended, prompted by the presence of the armed ...	2014	25549500
gastrointestinal and external parasites of the white-crested elaenia elaenia albiceps chilensis (aves, tyrannidae) in chile.	the objective of this study is to evaluate the ectoparasites and helminths of the white-crested elaenia, elaenia albiceps chilensis. feather mites anisophyllodes elaeniae, trouessartia elaeniae, and analges sp. were detected in 51% of birds (n=106), whereas 24% were infected with lice (tyranniphilopterus delicatulus, menacanthus cfr. distinctus, and ricinus cfr. invadens). helminths viguiera sp. and capillaria sp. were found in five of the birds that were necropsied (n=20). with the exception of ...	2015	26444059
migratory timing, rate, routes and wintering areas of white-crested elaenia (elaenia albiceps chilensis), a key seed disperser for patagonian forest regeneration.	migratory animals often play key ecological roles within the communities they visit throughout their annual journeys. as a consequence of the links between biomes mediated by migrants, changes in one biome could affect remote areas in unpredictable ways. migratory routes and timing of most neotropical austral migrants, which breed at south temperate latitudes of south america and overwinter closer to or within tropical latitudes of south america, have yet to be described in detail. as a result, ...	2017	28182628
nest-site selection and breeding success of passerines in the world's southernmost forests.	birds can maximize their reproductive success through careful selection of nest-sites. the 'total-foliage' hypothesis predicts that nests concealed in vegetation should have higher survival. we propose an additional hypothesis, the 'predator proximity' hypothesis, which states that nests placed farther from predators would have higher survival. we examined these hypotheses in the world's southernmost forests of navarino island, in the cape horn biosphere reserve, chile (55°s). this island has be ...	2020	33005489
