MORPHOLOGICAL VARIATION IN BOLITOGLOSSA VALLECULA (AMPHIBIA: CAUDATA: PLETHODONTIDAE) IN THE CORDILLERA CENTRAL OF COLOMBIA VARIACIÓN MORFOLÓGICA EN BOLITOGLOSSA VALLECULA (AMPHIBIA: CAUDATA: PLETHODONTIDAE) EN LA CORDILLERA CENTRAL DE COLOMBIA

Actualidades Biológicas, 2011
ABSTRACT: Body size and head shape variation was quanti ed in four populations of Bolitoglossa vallecula in the Cordillera Central of Colombia. two of these four populations occurred in sympatry with B. ramosi, an ecologically similar salamander species that could potentially compete with B. vallecula for food resources. there was no evidence of sexual

Tropical Bee Assemblage Diversity Decreases With Elevation While Body Size Increases

Biotropica, Volume 58, Issue 4, July 2026.
Photos of bee specimens collected in the Colombian Andes across a nearly 3000 m elevational cline. They are arranged to illustrate both the decline in richness with elevation and the increase in community average body size with elevation. ABSTRACT Elevation gradients are powerful drivers of changes in species composition, richness, and functional ...

DISTRIBUCIÓN DEL AGUA LLUVIA EN TRES BOSQUES ALTOANDINOS DE LA CORDILLERA CENTRAL DE ANTIOQUIA, COLOMBIA RAINFALL DISTRIBUTION IN THREE HIGH ANDEAN FORESTS IN THE CENTRAL CORDILLERA OF COLOMBIA

Revista Facultad Nacional de Agronomía Medellín, 2010
Se estudió la distribución del agua lluvia durante tres años en un bosque climácico de roble (Quercus humboldtii) y dos plantaciones forestales, de pino (Pinus patula) y ciprés (Cupressus lusitanica) ubicados en los Andes colombianos. Los principales ingresos de agua al bosque ocurrieron por la lluvia, cuyo valor medio anual fue 1.700 mm año-1.
