A test of the Acoustic Adaptation Hypothesis in three types of tropical forest: degradation of male and female Rufous-and-white Wren songs
(2016)Many animals produce complex vocalizations that show pronounced variation between populations. The Acoustic Adaptation Hypothesis helps to explain this variation, suggesting that acoustic signals are optimized for transmission ... -
Changes in nesting sites abundance and their use by woodpeckers along an urban gradient: a ten-year comparison
(2019)Woodpeckers nesting substrate abundance may be reduced by urban expansion, negatively affecting their reproduction. Long-term studies in the tropics are rare but valuable to estimate how urban development has affected ... -
Cyrtidiorchis gerardii
(2017)Cyrtidiorchis Rauschert is a small genus of some fve species distributed from Colombia and Venezuela to Peru, phylogenetically related to Sauvetrea Szlach. and Mormolyca Fenzl (Maxillarinae). Tey are characterized by ... -
Genetic structure in neotropical birds with different tolerance to urbanization
(2022)Gene flow in birds can be affected by urbanization depending on natural history traits and adaptability to habitat change. Contrasting results can be expected when comparing species with opposite resilience to urbanization. ... -
Is black plumage an adaptation to high elevations in a cosmopolitan bird genus?
(2019)Black plumage is expected to absorb and retain more heat and provide better protection against UV radiation compared with lighter plumages. Black plumage is common in species of the genera Turdus and Platycichla that inhabit ... -
Nest and eggs of the southern Central American endemic Tawny-chested Flycatcher Aphanotriccus capitalis
(2017)The Aphanotriccus, Lathrotriccus and Cnemotriccus clade (Cicero & Johnson 2002, Ohlson et al. 2008, Tello et al. 2009) comprises five species of tyrant flycatcher that inhabit dense second growth, disturbed forest, riverine ... -
Nest architecture and parental care in Ruddy Treerunner Margarornis rubiginosus
(2018)We complement the only existing nest description for Ruddy Treerunner Margarornis rubiginosus and include observations of nestbuilding and breeding behaviour. We also compare our data with existing information on nest ... -
Plant diversity in the diet of Costa Rican primates in contrasting habitats: a meta-analysis
(2023)In human-modified tropical landscapes, the survival of arboreal vertebrates, particularly primates, depends on their plant dietary diversity. Here, we assessed diversity of plants included in the diet of Costa Rican ... -
Relative Importance for Lincoln’s Sparrow (Melospiza lincolnii) Occupancy of Vegetation Type versus Noise Caused by Industrial Development
(2022)Anthropogenic noise can create an acoustic environment detrimental for animals that communicate using acoustic signals. Currently, most studies of noise and wildlife come from traffic noise in cities. Less is known about ... -
The biogeographic and evolutionary history of an endemic clade of Middle American sparrows: Melozone and Aimophila (Aves: Passerellidae)
(2017)The large number of endemic species in Middle America is frequently attributed to the interplay of geographical barriers and historical climatic changes in the region. This process promotes genetic divergence between ... -
The use of artificial substrate and materials for nest building in 2 ground-finches (Geospiza spp.) under human-altered conditions
(2021)Urbanization is one of the main problems for biodiversity around the world, associated with a decrease of natural habitats and its resources. In contrast, urbanization can also provide new resources that could be used by ... -
Unusual records of waterbirds in Costa Rica: possible connection to El Niño 2015-2016
(2016)These records were reported during the winter migrations in 2015 and 2016; five of the six species were apparently migrating from their reproductive sites in North America to their wintering grounds on the Pacific coast ... -
Urbanization, habitat extension and spatial pattern, threaten a Costa Rican endemic bird
(2021)Introduction: Migration of people from rural environments to cities has accelerated urbanization and modified the landscape as well as the ecological processes and communities in these areas. The Costa Rican endemic Cabanis´s ...
