This Data Release provides tabular and geospatial data digitized by the U.S. Geological Survey (USGS) from a U.S. Bureau of Mines (USBoM) report titled Mineral Investigation of Sangre de Cristo Wilderness Study Area, Alamosa, Custer, Fremont, Huerfano, and Saguache Counties, Colorado. The original p

In small temporary ponds (“Kettle Ponds”) near the Rocky Mountain Biological Laboratory in Gothic, Colorado, several species of detritivorous caddisflies coexist as detritus processors. Three congeneric caddisflies, Limnephilus externus, Limnephilus sublunatus, and Limnephilus tarsalis play an impor

Dispersal is the permanent relocation of an individual away from its natal burrow. This phenomenon is male biased in many mammal species and potential causes include inbreeding avoidance or resource competition. In this study, the dispersal behavior and exploratory excursion distances were recorded

We studied the effects of food availability and predator cues on mayflies at the Rocky Mountain Biological Laboratory (RMBL) in Gothic, CO. Organisms in a wide variety of ecological systems must deal with trade-offs between functions necessary to sustain their populations. Specifically, we were inte

The purpose of this experiment was to investigate the relationship between the different genders of the gynodioecious species P. foliosissimum and their mycorrhizal associates. Mcyorrhizal colonization of roots was quantified, and soil and plant tissue analyses were performed. Further, a full factor

In this study I examined the effects of phenotypic plasticity and local adaptation to light environment in the crucifer Cardamine cordifolia, at the Rocky Mountain Biological Laboratory, in Gothic, Colorado. Previous work by Louda and colleagues showed that plants in sun environments were subject to

Mutualisms are mutually exploitative relationships in which the benefits to both partners outweigh the costs. Mutualisms are expected to exist in a fragile balance, and these interactions may vary, both across their geographic range and temporally. Valeriana edulis, a dioecious perennial, is host to

A central question in the study of biodiversity is, what mechanisms allow species to coexist? While most attention to this question has focused on antagonistic species interactions, positive species interactions have recently gained attention and may rival antagonisms in their importance. Grasses wi

Individuality is defined as the characteristics that determine the differences from one individual in species from another individual of the same species. Many animals use acoustic signals to communicate. These signals send messages about territorial defense, mate attraction and kin-ship. The abilit

The phenology of plants in the alpine environment of the Rocky Mountains is heavily dependent on snowmelt time (Inouye and McGuire 1991, Thomson 2010). In this study we have manipulated the timing of snowmelt in order to change the phenology of Delphinium nuttallianum in the subalpine environment of
