Invertebrate predator-prey interactions and stream community structure
The evolution of transitions between pollination modes in <i>Penstemon</i>
Sex ratio and reproductive success along elevational gradients of gynodioecious populations of <i>Geranium richardsonii</i>
We studied the sex-ratio and reproductive success of gynodioecious populations of Geranium richardsonii along elevational gradients near Gothic, Colorado. Gynodioecious means that the species produces hermaphrodite and female plants. The hermaphrodites have male (anthers and pollen) and female (ovul
Morph- and sex-specific differences in corticosterone of Arizona tiger salamanders (<i>Ambystoma mavortium nebulosum</i>)
Chronic stress can have detrimental effects on long-term health of amphibians. Sex and morph may cause variation in stress within salamanders such as the Arizona tiger salamaders (Ambystoma mavortium nebulosum) at the Mexican Cut Nature Preserve due to differences in biotic or abiotic conditions (
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
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

Pollen thieving and pollen limitation in gynodioecious <i>Polemonium foliosissimum</i> (Polemoniaceae)
The limitation of pollen available to pollinators and visitors alike may potentially direct pollinator visitation choice as well as the plant’s ability to provide pollen rewards, nectar rewards, and plant defense mechanisms. Such trade-offs exist in Polemonium foliosissimum A. Gray (Polemoniaceae) a

Microvirus Genomes Identified in Fecal Samples from Yellow - Bellied Marmots
Mule deer (<i>Odocoileus hemionus</i>) respond to yellow-bellied marmot (<i>Marmota flaviventris</i>) alarm calls
Individuals may obtain valuable information about the presence of predators by eavesdropping on heterospecific alarm signals. While playback studies have demonstrated that similarly-sized and taxonomically-related species may respond to the calls of each other, less work has been done to define the
