Asociación entre la morfología alar y el uso del hábitat en seis especies de palomas (Columbidae) neotropicales
Relationship between wing morphology and habitat use in six species of Neotropical doves (Columbidae).
(2019)
Biomechanics, behavior, and natural history influence wing dimension and shape. Wing design often correlates with features of the habitat in which each species is found. Doves and pigeons (Columbidae family) range from ...
Range expansion and noteworthy records of Costa Rican birds (Aves)
(2018-01-19)
We present new distribution information for 19 species of Costa Rican birds. Thirteen species show changes in altitudinal distribution, 9 are recorded at higher elevations such as Egretta rufescens (Gmelin, 1789), Heliomaster ...
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. ...
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 ...
Rapid diversification of the Variable Seedeater superspecies complex despite widespread gene flow
(2022)
Disentangling the evolutionary relationships of rapidly radiating clades is often challenging because of low genetic differentiation and potentially high levels of gene flow among diverging taxa. The genus Sporophila ...
