Beneath the Burden we Place Upon It

Wisconsin Life: A Walk through the Cedarburg Bog

European settlers to Wisconsin saw wetlands as wasted space to be drained. But that view changed over time, and in 1952, Wisconsin’s DNR made an intact wetland in Ozaukee County known as the Cedarburg Bog a Wisconsin State Natural Area, only the second piece of land to receive that designation at the time.

Isolation of Novel Microbes from Natural Environments

About 95-99% of the microbes cannot be isolated with conventional methods. In this study, we used culture-independent methods to isolate and identify microbes in natural environments. We collected soil samples from different locations at the Field Station. The r-DNA of the microbes were sequenced to study bacterial phylogeny and taxonomy. The potential natural compounds produced from the isolated microorganisms were evaluated.

Experimental Evidence that Brighter Males Sire More Extra-pair Young in Swallows

Across taxa, extra-pair mating is widespread among socially monogamous species, but few studies have identified male ornamental traits associated with extra-pair mating success, and even fewer studies have experimentally manipulated male traits to determine if they are related directly to paternity. As a consequence, there is little evidence to support the widespread hypothesis that females choose more ornamented males as extra-pair mates.

Bat Activity Surveillance Monitoring at Neda Mine Hibernaculum

White-Nose Syndrome (WNS) has spread across 26 states and 5 Canadian provinces. The fungus Psuedogymnoascus destructans (Pd) that causes the syndrome has been found in four other states (MN, MS, NE and OK). This deadly disease has and continues to cause massive bat mortality in eastern North America. Since the winter of 2006–2007, bat population declines ranging from 80–97% have been documented at surveyed hibernacula.

Differential Contributions of Multiple Bumble Bee Species on Reproductive Success and Mating Patterns in Mimulus ringens

Over the last decade there have been startling changes in the relative abundance and diversity of bumble bee populations, including significant decline of many species both in North America and Europe. Several species often coexist within a population and it is not known whether these species provide equivalent pollination services for native flowering plants.

An Urban Cooper’s Hawk Nesting Study in the Metropolitan Milwaukee Area

The objectives of this study are to gather baseline data on the reproductive success of Cooper’s hawks (Accipiter cooperii) in the urban metropolitan Milwaukee area, to describe urban nesting habitat, and to compare these data with other Cooper’s hawk studies in Wisconsin. Long-term objectives are to determine Cooper’s hawk nest site fidelity, breeding population mortality and recruitment, population growth trends, immigration and emigration patterns, and natal dispersal patterns for the same urban population.

Natural Selection by Insect Pollinators and Seed Predators on Floral Head Traits of Helianthus grosseserratus (Sawtooth Sunflower)

Flowering plants must invest energy and resources to produce floral displays that are attractive to pollinators, but these same displays may also attract detrimental insects. How floral traits are shaped by the preferences of both pollinators and herbivores/ seed predators is not fully understood. Using Helianthus grosseserratus (sawtooth sunflower) as my study species, I investigated these conflicting selective pressures on floral head traits through a 2-year study in a large, unbroken tract of mesic prairie in Wisconsin.

PhenoCam Monitoring of Seasonal Plant Development and Senescence At Downer Woods and the UWM Field Station

An exciting new development in phenological science is the use of fixed cameras to provide continuous near-surface remote sensing observations of seasonal development and senescence within small patches of vegetation.

Social and Ecological Causes of Variation in Mating Signals and Mate Preferences

We are testing the hypothesis that social and ecological environments influence the expression of mating signals and mate preferences. Using members of the Enchenopa binotata treehopper species complex (Hemiptera: Membracidae), we are testing the interaction between social and host plant environments.
