The Population and Community Ecology (PACE) Lab is overseen by Dr. Michael J. Dreslik. The four programs of the lab are the Urban Biotic Assessment Program (UBAP), which provides environmental expertise to the Illinois Tollway, the Amphibian and Reptile Conservation (ARC) program, the Freshwater Mollusk Ecology and Conservation (FMEC) program, and the Environmental Education Program (EEP).

Our #WhatIsItWednesday didn't fool our followers!The Viceroy (Limenitis archippus) is often mistaken for the Monarch (Danaus plexippus). The Monarch is larger than the Viceroy, but the best way to tell them apart is to look for the bar across the hindwing of the Viceroy. It is visible on the upper and undersides of the wing, so even if wings are folded, you should be able to see it on the Viceroy. It used to be taught that Viceroy mimics the Monarch for protection, but it has been found that both species actually produce toxin. Viceroy caterpillars feed on willows, taking in salicylic acid resulting in its bitter taste. They overwinter in the caterpillar stage, wrapped in a leaf, another difference from the long distance migrant Monarch. #biodiversity #insects #insect #insectsofinstagram #bugs #entomology #butterfly #butterflies #butterfliesofinstagram #lepidoptera #NationalPollinatorWeek ...

Massasauga hibernacula at Carlyle Lake are genetically distinct units

Genetic analysis shows that the Eastern Massasauga hibernacula at Carlyle Lake are genetically distinct units. Once found across the northern two-thirds of Illinois, populations of the Eastern Massasauga have declined, with only one known population remaining in Illinois. Our long term studies have found the top four sources of mortality to include automobiles, predation, management …
