Reproductive ecology of Erigeron speciosus, a montane perennial herb: Evidence of self-incompatibility
Realizamos un experimento para determinar la biología reproductiva de Erigeron speciosus (Asteraceae), una hierba montano perenne que se extiende por el Oeste de Norteamérica. Polinización de E. speciosus fue manipulado para entender: (1) >cuál es el sistema de apareamiento para E. speciosus (cruzam

Salamander cannibalism
Nutrient niche dynamics among wild pollinators
Food underpins fitness and ecological interactions, yet how nutrient availability shapes species interactions in natural communities remains poorly understood. Most nutritional ecology research focuses on laboratory or single-species systems, limiting insight into how nutrient use and nutrient niche
A note comparing the primary structure of the arctic ground squirrel and the yellow-bellied marmot hemoglobin B chains
Hemoglobin β chains were isolated from both the arctic ground squirrel (Citellus parryii undulatus) and the yellow-bellied marmot (Marmota flaviventris). After various enzymatic and chemical cleavages, the primary structures of these β chains were determined. Only one sequence difference was found b
Delayed egg hatching and semivoltinism in the nearctic stonefly <i>Megarcys signata</i> (Plecoptera:Perlodidae)
Delayed egg hatching can influence the survival of aquatic insects by reducing exposure to competi- tors, predators, parasites, or unfavorable environmental conditions. We examined egg development in a Colorado population of the stonefly, Megarcys signata (Plecoptera: Perlodidae), whose larvae in- h
Factors affecting male song evolution in <i>Drosophila montana</i>
Late Pleistocene Herpetofauna from Two High-Elevation Caves in the Upper Gunnison Basin, Colorado
Las cuevas Cement Creek y Haystack en Colorado han producido un diverso registro de mamíferos de gran altitud del Cuaternario tardío. Entre los abundantes restos de mamíferos, se registraron raros casos de anfibios y reptiles, los cuales reportamos a continuación. En la cueva Cement Creek (2860 m de
Evaluation of cloud height, optical thickness, and phase retrievals from the CHROMA algorithm applied to Sentinel-3 OLCI data
Terrestrial ecosytem feedbacks to global climate change
Anthropogenic greenhouse gases are expected to induce changes in global climate that can alter ecosystems in ways that, in turn, may further affect climate. Such climate-ecosystem interactions can generate either positive or negative feedbacks to the climate system, thereby either enhancing or dimin
