Integrating Estuarine Water-Quality Data in Northeastern National Parks

Estuaries worldwide are threatened by nutrient over-enrichment from watershed development. USGS led development of a regional protocol to monitor estuarine nutrient status in northeastern coastal National Parks. Synthesis and reporting of monitoring results at local and regional scales allows park managers to identify changing nutrient loads and susceptibility to eutrophication.

Variation in Stable Isotope Ratios of Eelgrass to Detect Trends in Estuarine Nutrient Status

Seagrasses are among the most productive ecosystems on the planet. Worldwide losses of this important habitat have been caused by water quality degradation association with watershed development. Improved approaches to detect threats of nutrient enrichment are paramount to seagrass conservation.

American Black Duck and Threat of Avian Influenza

The Challenge: The genomic revolution is giving wildlife biologists new tools to assess the role of wildlife in spreading diseases that affect human populations.   Peptide arrays are a high throughput technology that gives unprecedented breadth and depth of information about the immune system.  We are using peptide arrays to assess the immune responses of Chesapeake Bay waterfowl to avian...

Disease Resistance of Wildlife Species: how the immune system evolves and adapts

The Challenge: In an era when emerging infectious diseases are steadily increasing, human populations are exposed to virulent new pathogens.  Insight into the human system can be gained from understanding the variety of immune adaptations of wildlife species.  The vertebrate immune system is not static.  Rather, it involves in response to the environment.

Sustainably Designed Trails: Recent Recreation Ecology Findings on Design Factors Affecting Soil Loss

An estimated 146 million Americans participated in more than 10.9 billion outdoor recreation activities in 2017. Virtually all protected natural areas have recreational trails as an essential infrastructure component to accommodate these outdoor recreation activities and visitor access, supporting a diverse array of opportunities and experiences that include nature study, hiking, camping,...

A Vaccination Program to Protect Endangered Whooping Cranes from Encephalitis Virus

The Challenge: In eastern North America there is a viral disease called Eastern Equine Encephalitis, or EEE. This virus is transmitted among native bird species by the mosquito, Culiseta melanura, but does not cause disease in these passerine species. However, the virus is capable of causing severe disease or death in horses, some game bird species, humans and whooping cranes. In the fall of...

Research and Management of Informal (Visitor-Created) Trails in Protected Areas

Protected area managers provide formal trail systems to accommodate recreational visitation on resistant “hardened” treads, while protecting off-trail vegetation, soils, and wildlife. When formal trail networks fail to provide visitors the access and experiences they require, visitors frequently venture “off-trail” to fish, hunt, explore, climb, or engage in other off-trail activities. Even...

Recovery of Eelgrass (Zostera marina L.) in Casco Bay, Maine, Following Destruction by European Green Crabs

Eelgrass provides essential functions to the ecology and economy of Maine’s coastal zone. When over half the eelgrass in Casco Bay, Maine, disappeared between 2012 and 2013, USGS experimental evidence identified disturbance from invasive European green crabs as the leading cause. Natural revegetation is occurring, but there is interest in learning whether restoration may hasten recover.

We estimated species frequency in vegetation plots using traditional point intercept methods. We also tested a rapid, digital method to take high-resolution digital photographs of plots. We navigated among plot locations...

Accumulating evidence in ecology: Once is not enough

Many published studies in ecological science are viewed as stand-alone investigations that purport to provide new insights into how ecological systems behave based on single analyses. But it is rare for results of single studies to provide definitive results, as evidenced in current discussions of the “reproducibility crisis” in science. The key...

Phenotypic plasticity or a reproductive dead end? Primnoa pacifica (Cnidaria: Alcyonacea) in the southeastern Alaska region

Red tree corals (Primnoa pacifica) are abundant in the eastern Gulf of Alaska, from the glacial fjords of Southeast Alaska where they emerge to as shallow as 6 m, to the continental shelf edge and seamounts where they are more commonly found at depths greater than 150 – 500 m. This keystone species forms large thickets, creating habitat for many...

Instructions for running the analytical code PAT (Purge Analyzer Tool) for computation of in-well time of travel of groundwater under pumping conditions

IntroductionUnderstanding the optimal time needed to purge a well while pumping to collect a representative groundwater sample requires an understanding of groundwater flow in wells (in-well flow). Parameters that affect in-well flow include the hydraulic properties of the aquifer, well construction, drawdown from pumping, and pump rate. The time...

Soil aggregates as a source of dissolved organic carbon to streams: An experimental study on the effect of solution chemistry on water extractable carbon

Over the past two decades, headwater streams of the northern hemisphere have shown increased amounts of dissolved organic carbon (DOC), coinciding with decreased acid deposition. The exact nature of the mechanistic link between precipitation composition and stream water DOC is still widely debated in the literature. We hypothesize that soil...
