| ABSTRACT Some species of mastiff bats, Molossus Geoffroy, 1805, inhabit human shelters such as houses and barns. Among them, the Pallas’s mastiff bat, Molossus molossus Pallas, 1766, is the most common species in South America. There are a few studies on this bat in Colombia, mostly on colony size, diet, ectoparasite records, and activity patterns in the Andean and Caribbean regions. Here, we provide information on the prevalence of chiggerfleas, Hectopsylla pulex (Haller, 1880), on M. molossus, along with molecular data on the flea, and its distribution in Colombia. In addition, we describe the size and sex ratio of the infested bat colony, located in the central Andes of Colombia. The bat colony was represented by ca. 45 individuals, of which 33 were... |

| Abstract Populations that breed along steep elevation gradients show diverse physiological and morphological changes in response to the different environmental conditions. The latter has been discussed by Bergmann’s and Allen’s ecogeographic rules about body and appendage sizes and environmental temperature. We compared morphometric measures (mass, bill width, tarsus, wing, and tail length) of a Zonotrichia capensis population in two localities at different elevations with similar latitudes and photoperiods on the western slope of the Colombian Central Andes. We compared a Low Elevation locality (LE) at 1800 m a.s.l. and a High Elevation locality (HE) at 3853 m a.s.l. that have approximate wind speeds of 1.3 m/s and 8.4 m/s, respectively. During 12 months... |
