Comparison of Bee Bowls and Netting for Monitoring Native Bees

This study looked at the differences in bee community composition between estimates obtained from pan traps vs. netting. Comparing species richness, evenness and community composition between the two sampling types from the years 2009-2017 and 2009-2021. Based on a rate of bees caught per hour, with

Native ant (<i>Formica rufa, Formica fusca</i>), <i>Nicrophorus spp.</i> interactions at small mammal carcass resources in the southern Rocky Mountains, Gunnison National Forest, Colorado.

Competition for carcass resources can be fierce with a broad range of taxa vying for control of the nutrient rich resource. Arthropod competition for carcasses is well studied. Flies, beetles, and ants are common carcass utilizers. The burying beetle (Nicrophorus spp). is an obligate carrion breeder

Ant Behavioral Responses to Aphids Colonizing <i> Ligusticum porteri </i>

Ant-aphid mutualisms are keystone interactions that, if altered, have the potential to cause cascading, multitrophic effects on local arthropod and plant communities. In our study system, the flowering stalks of Ligusticum. porteri (Apiaceae) are colonized by the aphid Aphis asclepiadis, which relie

Snowmelt Timing Leads to Plasticity and Alters Natural Selection on Leaf Traits in <i> Ipomopsis </i>

Anthropogenic climate change is altering environments, which in turn has the potential to influence plant traits (through phenotypic plasticity) and natural selection. The effect of changing climate on the strength and direction of selection remains unresolved. In this study we quantified the plasti

Is Compensatory Growth Costly?

1. Compensatory growth is well-studied and exhibited across a variety of taxa, including plants, invertebrates, and a variety of vertebrates. Compensatory mechanisms allow individuals to recover from adverse conditions, potentially enhancing survival and fitness. However, to compensate for a low bod

How understory bee communities compare to open meadows in the Rocky Mountains

Forest associated species, bees and otherwise, are among the world's most vulnerable species due human activity such as deforestation. Even though bees are significant to ecosystem health by providing such important services as pollination, basic information on bee biodiversity and factors driving t

Determining changes in floral volatile composition of <i> Ipomopsis aggregata </i> in response to nectar robbing and its associated microorganisms

Mutualisms involve complex relationships between multiple types of organisms. Traditionally, mutualisms like pollination have been studied using a pairwise perspective – only focusing on two individual species or groups of species with similar functions involved in the relationship. Including third-

Effects of clumping of <i> Delphinium barbeyi </i> on pollination

The spatial clustering of plants occurs for a variety of reasons, including the evolution of concentrated floral displays to attract more pollination. Within clusters, traits that attract pollinators may differ from non-cluster conditions– such as increasing floral display size andscent, which can c

The ecology and evolution of pathogens in a changing world

Infectious diseases are an integral part of natural ecosystems but also pose a serious threat to human health and agriculture. Understanding the multitude of factors shaping the epidemiology and evolution of pathogens is crucial for predicting and mitigating their effects, especially in a rapidly ch
