DNA Barcoding for Identifying Native Bee Species

The Challenge: Traditionally, bee identification has relied on taxonomic methods centered on descriptions of morphological differences between species. However, for many species, separate keys are required for identifying adult males and females and immature life stages. These keys are commonly unavailable. The lack of distinguishing morphological characters useful for separating closely...

Assessing Toxicogenomics Effects of a Synthetic Androgen on Japanese Quail and the Development of an Avian Vitellogenesis Model

The Challenge: Endocrine active chemicals (EAC) are known to interfere with hormonally regulated physiological processes, thereby affecting signaling in the hypothalamic-pituitary-gonadal-liver (HPGL) axis and commonly resulting in reproductive dysfunction. Computational models that relate hormonal and genomic biomarkers within the HPGL axis to the reproductive cycle and ecologically relevant...

The Role of Japanese Quail in Ecotoxicology

The Challenge: Wild birds are exposed throughout their lives to natural and synthetic chemicals that are present in the environment, many of which interfere with the animal’s physiological and developmental systems. Relative concentrations, routes, frequency, and the environment in which chemical exposure occurs will determine to a large extent the bird’s response. Well-designed avian field...

Population Genetics and Emergency Management of Two Kauai Island Endangered Species

The Challenge: The Akeke’e (Loxops caeruleirostris) and the Akikiki (Oreomystis bairdi), two species of Hawaiian honeycreeper, are critically endangered bird species endemic to high elevation ohia forests on the Hawaiian island of Kauai.  Both species have suffered severe population declines and range contractions in recent decades.  Akeke’e are currently thought to number ca. 950 wild...

Identifying the Genetic Basis of Avian Susceptibility to Mercury

The Challenge: Mercury is a highly toxic element found throughout our environment. Although it occurs naturally in some environments, human industrial pollution has greatly increased the amount of mercury and the range of environments in which mercury is found. Recent studies have confirmed clear differences in the sensitivity of various bird species to methylmercury. Because the causes of...

Analyzing the Gut Microbiome of Urban Canada Geese

The Challenge: The Canada Goose Branta canadensis was historically a highly migratory species.  However, this species has recently established resident populations in urban, suburban, and agricultural areas in many parts of the U.S., including the Chesapeake Bay region.  The enormous success of these populations has led to consideration of this species as a nuisance, largely due to its...

Assessing Adverse Outcomes Associated with Exposure of Birds to Flame Retardants

The Challenge: The use of flame retardants (FRs) as additives in a variety of consumer use products, including plastics, textiles, and electronics, is projected to continue and increase for the foreseeable future. Because of unanticipated environmental problems, some FRs have either been banned, restricted, or are being phased-out and replaced by other new and presumably safer FRs. Regrettably...

Transport and Fate of Nutrients

Eutrophication, or excess nutrients in streams, is typically one of the top reasons that a stream is listed as impaired on the 303(d) list as part of the Clean Water Act. How nutrients, primarily nitrogen and phosphorus, are transported to streams and groundwater greatly affects the best management plan to keep them on fields and out of streams and groundwater. Likewise, environmental managers...

Assessing the impacts of future climate conditions on the effectiveness of winter cover crops in reducing nitrate loads into the Chesapeake Bay Watershed using SWAT model

Winter cover crops (WCCs) have been widely implemented in the Coastal Plain of the Chesapeake Bay watershed (CBW) due to their high effectiveness at reducing nitrate loads. However, future climate conditions (FCCs) are expected to exacerbate water quality degradation in the CBW by increasing nitrate loads from agriculture. Accordingly, the...

Long-term monitoring data provide evidence of declining species richness in a river valued for biodiversity conservation

Free-flowing river segments provide refuges for many imperiled aquatic biota that have been extirpated elsewhere in their native ranges. These biodiversity refuges are also foci of conservation concerns because species persisting within isolated habitat fragments may be particularly vulnerable to local environmental change. We have analyzed long-...
