Recent News: Check Out our Newest Publication!

Posted by Jenn Collins on July 29, 2021

In our newest publication, accepted and published on the Environmental Toxicology and Chemistry website, we assess vulnerabilities to pesticide exposures across multiple bee species. This analysis highlights several uncertainties in the use of the Western honey bee as a surrogate species for pesticide risk assessment based on various bee traits and ecologies.

Aquatic Systems Models: A Virtual Mesocosm Could be a Regulatory Tool of the Future

Posted by Jenn Collins on July 29, 2021

Aquatic mesocosm studies have long been considered a higher-tier tool for informing risk assessments under European regulations. These simulated pond studies are designed to investigate the impact of a pesticide on an aquatic ecosystem and use the complexities of multiple trophic levels and long-term study duration to observe patterns of impact and recovery. As presented… Read More>

Pop-GUIDE: Providing Risk Assessors with a Critical Population Modeling Tool

Posted by Jenn Collins on July 29, 2021

Population models provide a means for relating individual-level responses to a stressor to changes in population abundance and structure. The models’ value is in their ability to reduce uncertainty in the extrapolation of organism-level ecotoxicological observations and endpoints to ecologically relevant effects. However, there are many challenges incorporating population models into the ecological risk assessment… Read More>

Case Study: Application of an Ecological Model (BEEHAVE) to Large-Scale Honey Bee Colony Feeding Studies

Posted by Jenn Collins on July 29, 2021

In our June newsletter, we mentioned the recent release of a 2-part publication series in Environmental Toxicology and Chemistry presenting 1) a model validation of BEEHAVE and 2) an application of BEEHAVE. This month, we’re taking a deeper dive into these two publications and, through a case study, will show both how the BEEHAVE model… Read More>

Understanding the Complex Dynamics of Endangered Species and Pesticide Exposure through Population Modeling

Posted by Jenn Collins on July 29, 2021

Some species listed under the Endangered Species Act (ESA) occur in agricultural landscapes where their habitats have the potential to be exposed to pesticides. Aquatic species, in particular, may be at risk to pesticides applied to nearby agricultural fields, even though applications are not made directly to the aquatic habitat. Population modeling has emerged as… Read More>

Delicate pollinator-plant relationships: Forged through coevolution and critical considerations for risk assessment

Posted by Jenn Collins on June 7, 2021

Pollinator-plant relationships represent some of the most striking examples of mutualism and coevolution in all of nature. We’ve discussed in our pollinator protection article how native bees can be generalists, often thriving on a diverse availability of flowering plants. This diversity is a benefit to both bee and plant alike. From a bee’s perspective, diverse… Read More>

Recent and Upcoming Highlights from our Pollinator Protection Work

Posted by Jenn Collins on June 7, 2021

Much of the most recent research in pollinator protection, and in fact a lot of new ecological research in general, is focused on computer model simulations, such as the BEEHAVE model. In particular, recent honeybee-specific projects have incorporated BEEHAVE to simulate the development of a honeybee colony and its nectar and pollen foraging behavior in… Read More>

Let’s bee informed about honey bee foraging

Posted by Jenn Collins on June 7, 2021

There is something mesmerizing about watching bees at work! These little workers have been agriculturally critical to humans for thousands of years, and over this extended time, we have accumulated a wealth of research about their physiology and behavior. Here, we focus on honey bee foraging behavior, which provides us with a fascinating example of… Read More>

There are so many more bees beyond honey bees: It’s time to show our native bees some love!

Posted by Jenn Collins on June 7, 2021

Did you know that there are over 20,000 recognized species of bees around the world, 4,000 of which are native to the United States? Although pollinator protection efforts have been a core focus in ecological stewardship, most of us tend to focus on the European honey bee (Apis mellifera) and miss out on the bulk… Read More>

Protecting pollinators in your own backyard

Posted by Jenn Collins on June 7, 2021

Pollinator protection has long been a significant initiative for agriculture and environmentalists, making the recent threat of diminishing pollinator populations cause for increased concern. Fortunately, as we have learned from society’s response to other environmental concerns like water pollution, when an environmental issue becomes a hot topic in the general population, significant action takes place….
