Microclimate observations associated with snowmelt experiment gradient sites, East River, Colorado, 2017 to 2020
The timing of snowmelt in mountain systems is a main driver of vegetation phenology and production, as well as recharge of soil moisture and ground water. Decreases in maximum snowpack and warmer spring temperatures have led to a higher frequency of early snowmelt. This study combines a natural elev
East River Surface and Pore Water FTICR-MS Data Associated with “Implications of sample treatment on characterization of the riverine environmental metabolome”
Surface and pore water samples were collected from distributed locations around Meander A in East River (Crested Butte, CO, USA) during the summer of 2018. This dataset consists of the characterization of dissolved organic matter using 12 Tesla Fourier transform ion cyclotron resonance mass spectrom

East River Watershed Stable Water Isotope Data in Precipitation, Snowpack and Snowmelt 2016-2020
Stable water isotopes (d18O, d2H and d-excess) are important tracers in hydrologic research to understand water partitioning between vegetation, groundwater, and runoff but are rarely applied to large watersheds with persistent snowpack and complex topopgraphy. Data were collected for the Lawrence B
Long-term effects of mining on the benthic macroinvertebrate community of a stream in Paradise Basin
Competition between <i></i>Nicrophorus investigator<i></i>, <i></i>Nicrophorus defodiens<i></i>, and <i></i>Thanatophilus lapponica<i></i> for carrion resources
Climate Change is Causing A Decline in Bombus occidentalis by Reducing its Floral Resources
Concerns of the decline of pollinators and their services have recently been raised. While several hypothesis have been studied, such has the shift of flowering phenology so it no longer overlaps with pollinators and habitat fragmentation, this study investigated the decline of the nectar robbing bu
What determines the distribution of red-naped sapsuckers in the East River Valley?
The conservation of keystone species and their associates is of great importance due to the disproportionately large role they play in community and ecosystem structure. The Red-naped Sapsucker (Sphyrapicus nuchalis) is considered part of an intricate keystone species complex in the aspen forests of
The importance of parasitism and body condition in explaining variation in anti-predator vigilance in the yellow bellied marmot (<i>Marmota flaviventris</i>)
Butterfly foraging behavior: can butterflies detect nectar in flowering plants?
Optimal foraging theory states that there are benefits and costs from foraging. If the animal shows optimal foraging behavior, the benefits minus the costs from foraging should be maximized. One assumption of optimal foraging theory is that animals can recognize food, which for butterflies means det
Pollinator-mediate selection in Ipomopsis aggregata: does correlational selection explain floral phenotypes?
The theory of pollination syndromes is pervasive in pollination biology. Correlational selection may explain why certain flower phenotypes are selected for by certain pollinators thereby offering support for the theory of pollinations syndromes. Using potted individuals of the hummingbird-pollinated
Natural security: a darwinian approach to a dangerous world
A mitochondrial-DNA-based phylogeny for some evolutionary-genetic model species of <i>Colias</i> butterfly (Lepidoptera, Pieridae)
Hydraulic and geomorphic effects on mayfly drift in high-gradient streams at moderate discharges
We investigated relationships between geomorphic and hydraulic factors and invertebrate drift in high-gradient streams. We measured drift density of a highly mobile mayfly (Baetis bicaudatus) into and out of 12 stream reaches in western Colorado, as well as benthic density and abiotic variables with
Social network analysis of animal behaviour: a promising tool for the study of sociality
A prospective overview of social network analysis' general utility for the study of animal social behaviour is provided and relevance and constraints of some network measures are highlighted.
