Sexual size dimorphism and acoustical features of the pre-advertisement and advertisement calls of Rhinophrynus dorsalis Duméril & Bibron, 1841 (Anura: Rhinophrynidae)
(2015)
Las interacciones entre selección natural, selección sexual, y los requerimientos ecológicos específicos de las especies son responsables de la evolución de comportamientos complejos de cortejo y estrategias reproductivas. ...
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 ...
Effect of urbanization on the avifauna in a tropica metropolitan area
(2011)
The rapid and unplanned expansion of urban areas is a common pattern in neotropical developing countries. Urbanization has eliminated or drastically altered large areas of natural habitats used by the rich neotropical ...
Observations on the breeding behaviour of Snowy Cotinga
(2016)
Tres nidos de la Cotinga Nivosa Carpodectes nitidus muestran un diseño muy simple, que consiste en una plataforma construida de ramitas y zarcillos, similar al descrito previamente para esta especie y para otras cotingas. ...
The effect of noise variation over time and between populations on the fine spectrotemporal characteristics of different vocalization types
(2021-01)
Noise affects the recognition of acoustic signals by masking information. To compensate for increased noise, individuals often increase the minimum frequency of their vocalization to reduce noise interference. Our goal was ...
Web building behavior in a wall spider (Oecobiidae) suggests a close relationship with orb-weavers
(2022)
Behavior is often phylogenetically informative and detailed descriptions of
behavior have been used to support taxonomic relationships in several groups, such
as birds, lizards, and arthropods. Web building behavior has ...
Variation and possible function of egg sac coloration in spiders
(2013)
Coloration of the egg sacs of spiders varies widely to the human eye, both across and within taxonomic groups. These differences in coloration are expected with differences in the biology and ecology of different species. ...
Artificial cavities and substrates for cavity-nesting birds in Neotropical urban environments: A novel resource or the last opportunity to breed?
Cavidades y sustratos artificiales para aves que anidan en cavidades en un entorno urbano Neotropical: ¿un nuevo recurso o la ´ultima oportunidad para reproducirse?
(2021)
Urban development reduces the abundance of most natural resources for some birds but also provides new opportunities for others. One group that is more likely affected by urban development is the cavity-nesting species ...
Effect of El Niño and La Niña on abundance of frugivorous and nectarivorous terrestrial birds in three tropical forests
El efecto de El Niño y La Niña sobre la abundancia de aves frugívoras y nectarívoras terrestres en tres bosques tropicales
(2019-05-14)
El Niño and La Niña climatic oscillations have dramatic effects on population dynamics and community
structure of different animals. For marine birds, El Niño phenomenon drastically increases their mortality
and reduces ...
