SYNOPSIS This papers concerns the method of river-stage forecasting for the Colorado River and its principal tributaries, the Green, Grand, and San Juan Rivers. A brief description of the topographic features and courses of these streams is given. Attention is given to temperature conditions, as the

Formica obscuripes, or the Western Thatching Ant, is a native North American ant species commonly found throughout the central and western US. Like many ant species, F. obscuripes acts as an ecosystem engineer, as colonies can significantly alter the nutrient content, moisture content, temperature,

Environmental variation often induces shifts in functional traits, yet we know little about whether plasticity will reduce extinction risks under climate change. As climate change proceeds, phenotypic plasticity could enable species with limited dispersal capacity to persist in situ, and migrating p

Long term data on stages of plant succession on bare areas is extremely useful in determining patterns of revegetation over longer periods of time. Understanding of these patterns can have application in conservation and restoration. This study examined plant community composition data for a subalpi

An earthflow that occurred in Gunnison County, Colorado created a natural laboratory to study plant succession. Plant succession and ants can effect the soil composition of grounds left bare and depleted of organic matter by the landslide. This study was conducted to examine if the described success

A 22 year warming experiment at Rocky Mountain Biological Laboratory has elucidated short term (15 year) responses in plant community and soil organic carbon to artificial warming. This summer’s research evaluates long-term (>15 year) changes and, because of recent climate change effects, the releva

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

Animal communication is vital to nearly every species. Serving multiple functions and being conveyed throughout a variety of modes, communication allows animals to make decisions based on information other animals provide. Numerous examples of this can be found across the animal kingdom, with bioflu
