Using specimens to create a pollinator community assessment of restored tallgrass prairie

-- Contributed by Heather Cray, Department of Environment and Resource Studies, University of Waterloo

Animal species need space – a place to forage, grow, and nest. This is especially true of Lepidoptera (butterflies and moths), whose caterpillars generally feed exclusively on one genus or species of host plant (think monarch butterflies and milkweed). For the 4,000 or so species of native bees in North America, required forage plants and nesting sites vary from common suburban offerings (e.g., patches of bare ground, maples, willows, clover), to specialized needs which are ecosystem-specific.  Enter tallgrass prairie – a grassland ecosystem with high forb diversity that supports a dizzying array of invertebrate life. As our continent’s most endangered ecosystem, the 1-3% that remains is a mix of remnant and restored habitat, and restoration efforts-- both large and small, are ongoing. Read more here.

The scientific view from behind the microphone

Imagine it.  The sweaty palms, the nervous fidgeting. You're sitting in the waiting room of the radio station, the governors' office, or waiting to speak with the Chair of your Department.  You begin question your preparation - What is the key message and main talking points? Is there an engaging and relevant story to highlight the science? Does it fit with the audience you will be engaging with? You begin cursing that you didn't have more practice!

Collecting trends: how wars and human history influence biological collections

-- Contributed by Vaughn Shirey, The Academy of Natural Sciences of Drexel University

A large portion of my research in The Gelhaus Lab at The Academy of Natural Sciences of Drexel University relies heavily on digitized specimen data and metadata, specifically the who, when, and where of specimen collection. “Big data” research has risen in popularity since high-performance computing has made it easier for researchers to conduct analyses of groups of organisms overnight; however, additional considerations to the use of large datasets should be taken into account. My research focuses on the historical biases present in natural history collection data, including identifying collection bias and gaps in data due to human history. Read more here.
