Mapping the range shifts of East River Valley caddisflies <i> (Trichoptera) </i>
Range shifts occur when all individuals of a species or population move from a previously- habitable area to a newly-habitable area in response to changing environmental conditions. Climate- induced range shifts are well-documented for certain regions, biomes, and taxa, but large knowledge gaps exis
Exploring mechanisms explaining coexistence patterns of <i> Rhyacophila </i> species (Trichoptera) in streams near the Rocky Mountain Biological Laboratory
Coexistence of closely related species can be explained by a number of biotic and abiotic factors. In Trichoptera (caddisflies), the patterns of coexistence of the species Rhyacophila in streams near the Rocky Mountain Biological Laboratory (RMBL) has been tracked for 43 years. This study is a conti
Feeding Preference and Growth Effects for Three Trichoptera Species
Detritivores diets are very limited in key nutrients such as phosphorus, nitrogen, and fatty acids. This study looked at how detritivores caddisflies selected food based on nutrient quality. We set up controlled experiments to examine food preference and how that might affect overall growth. Our stu
Mayflies avoid sweets: fish skin mucus amino sugars stimulate predator avoidance behaviour of <i> Baetis </i> larvae
Nonconsumptive effects of predators can have knock-on effects on prey fitness, life history and population dynamics. However, the origin of cues stimulating predator avoidance behaviour and the mechanisms underlying prey responses need further investigation. Previous studies revealed that nonconsump
Influence of Metal Contamination and Sediment Deposition on Benthic Invertebrate Colonization at the North Fork Clear Creek Superfund Site, Colorado, USA
Assessing benthic invertebrate community responses to multiple stressors is necessary to improve the success of restoration and biomonitoring projects. Results of mesocosm and field experiments were integrated to predict how benthic macroinvertebrate communities would recover following the removal o
Spatial and Temporal Patterns of Coexistence in Closely Related <i>Rhyacophila</i> (Trichoptera) Species
Environmental change affects the survival, interaction and co-existence of species within an ecosystem. We studied multiple species of Rhyacophila, a primitive genus of caddisfly that, in its larval state, lives at the bottom of cold, oxygen rich and fast flowing streams. Previous research has shown
Nutrient excretion rates of common aquatic taxa in high elevation ponds at the Mexican Cut
Nutrient cycling is crucial for proper functioning of aquatic ecosystems. Animals play an integral part of this process, especially in nutrient poor ecosystems such as the high elevation ponds at the Mexican Cut Nature Preserve. Nutrients such as nitrogen (N) and phosphorus (P) are both limiting nut
Determining the Effects of Climate-Induced Range Shifts on Caddisfly Population Dynamics
The geographic distribution of many freshwater insects is restricted in part by timing of snowmelt and the temperature of the water. Because of this, climate change is having a significant effect on the distribution of aquatic species around Gothic, Colorado. Scientists have documented that species
Role of animal detritivores in the breakdown of emergent plant detrius in temporary ponds
High interspecific variation in nutrient excretion within a guild of closely related caddisfly species
AbstractUnderstanding the amount of variation in functional traits between closely related species within guilds is critical for understanding links between community composition and ecosystem processes. Nutrient excretion is an important link between animals and their environments, and aquatic inve
A Presence-Only Species Distribution Model Comparison Predicting the Distribution of the Amphibian Chytrid Fungus <i>(Batrachochytrium dendrobatidis)</i>
Impacts of Historical Hydroperiod on Bird Predation of Emergent Aquatic Insects
As global climate changes ephemeral freshwater systems face changes in historical hydroperiod with a shift towards shorter wet periods. Vernal ponds are one such type of lentic ephemeral system; in general they are relatively small and shallow, which causes them to dry in late spring or early summer

Blooms of benthic diatoms in phosphorus-poor streams
During the past 50 years, freshwater ecologists have mostly attributed massive accumulations of algal biomass in lakes and rivers to high nutrient inputs. While researching the role that phosphorus (P) plays in increasing diatom biomass in rocky-bottomed rivers, I (MLB) was puzzled by the presence o
Influence of Parasitism on Consumer Driven Nutrient Recycling by Aquatic Insects
Parasites have only recently gained the attention they deserve in studies involving their role in ecosystems. Using ecological stoichiometry will allow parasite roles to be established. I attempted to establish parasite effects on hosts by measuring the excretion Nitrogen:Phosphorus of infected Mega
Writing an Effective Response to a Manuscript Review
An author’s response to referees’ comments is a key component of the peer review process that affects whether a manuscript is accepted or rejected, the speed at which a manuscript moves through the review process, the workload of editors and referees, and the quality and clarity of published science
A model of inter-cohort cannibalism and paedomorphosis in Arizona tiger salamanders, <i>Ambystoma tigrinum nebulosum</i>
Cannibalism is widespread in size-structured populations. If cannibals and victims are in different life stages, dominant cohorts of cannibals can regulate recruitment. Arizona Tiger Salamanders, Ambystoma tigrinum nebulosum, exhibit facultative paedomorphosis in which salamander larvae either metam
