Microplastics (i.e., plastics measuring less than 5mm) pollution is a growing problem affecting coastal communities, marine ecosystems, aquatic life, and human health. The widespread occurrence of marine microplastics, and the need to curb its threats, require expansive, and continuous monitoring. W

The relative contributions of recruitment and post-recruitment processes are pivotal to understanding the mechanisms influencing the population dynamics of organisms. We estimated recruitment by oviposition to populations of the mayfly Baetis bicaudatus in multiple streams of one drainage basin in w

Recent blooms of Didymosphenia geminata in streams around the world where they had never been recorded before has generated new interest in the biology and ecology of this diatom. The species is often found in oligotrophic mountain streams where phosphorus limitation may determine productivity. Exce

Theory and empirical studies suggest that cannibalism in age‐structured populations can regulate recruitment depending on the intensity of intraspecific competition between cannibals and victims and the nature of the cannibalism window, i.e., which size classes interact as cannibals and victims. Her

Research in stream ecology has become imperative to protect the ecosystem from natural and human induced disturbances. By indulging in the variation of substrate makeup, light intensity, and current velocity, we can evaluate the composition of living organisms as well as the nutrients around them. T

Nutrient supply into an ecosystem is an important factor that can influence its productivity. While some nutrients enter the ecosystem from external sources, cycling of nutrients internally can also be an important process in determining nutrient supply. In this study I examined the role of benthic

Wetland nutrient cycling occurs through complex feedback mechanisms and dynamic inter- and intra-species interactions. In the shallow, oligotrophic ponds at the Mexican Cut Nature Preserve, near the Rocky Mountain Biological Laboratory in the Elk Mountains of Western Colorado, detritovore caddisfly

Excretion rate estimates are important for linking consumers to biogeochemical processes. Short-term incu- bations in chambers are a common approach for studies. This, however, may result in inaccuracies due to a well- documented decline in excretion with time, which is often attributed to fasting.

AbstractWe investigate herein the hypothesis that there is a significant relationship between bed particle mobility and benthic invertebrate abundance in the gravel‐bed channel of the upper Colorado River in Rocky Mountain National Park. A large diversion channel called the Grand Ditch normally dive

The influence of predators on drift and benthic density is important for understanding prey community structure in freshwater streams. Drift activity of stream invertebrates in fishless streams does not differ between day and night, but when visual drift-feeding trout are present, stream invertebrat

The process of manually diverting water from stream channels for agricultural purposes, industrial uses, and other reasons is practiced universally worldwide. These diversions of water are primarily characterized by a reduction in total flow within the stream. This study examines the response of ben

It is concluded that predation alone cannot explain variation in population dynamics of either mayfly species; and the relative importance of predation is species- and environment-specific compared to non-predatory losses, such as other agents of mortality and non-consumptive effects of predators.

Environmental factors influence variation in life histories by affecting growth, development, and reproduction. We conducted an experiment in outdoor mesocosms to examine how diet and a time constraint on juvenile development (pond-drying) influence life-history trade-offs (growth, development, adul

I examined the utility of the strontium isotope (87Sr/86Sr) ratio in fish otoliths to determine the origins and movements of invasive piscivores in the Upper Colorado River Basin (UCRB). My goal was to determine if invasive piscivores entered riverine habitat of endangered fishes in the UCRB by esca
