Informing planning and management through visitor experiences in Grand Staircase-Escalante National Monument Informing planning and management through visitor experiences in Grand Staircase-Escalante National Monument
Policies mandate that managers at Grand Staircase-Escalante National Monument must balance recreational opportunities with a variety of resource management and utilization activities across a vast and diverse landscape containing numerous Wilderness Study Areas and other lands containing spectacular resources. This balancing act is stressed by increasing levels of use and recent changes...

Intra- and interspecific variation in production of bile acids that act as sex pheromones in lampreys Intra- and interspecific variation in production of bile acids that act as sex pheromones in lampreys
Pheromones are important sexual signals in most animals, but research into their evolution is largely biased toward insects. Lampreys are a jawless fish with a relatively well-understood pheromone communication system and offer a useful opportunity to study pheromone evolution in a vertebrate. Once sexually mature, male sea lamprey (Petromyzon marinus), and likely other lampreys, produce...

Phylogeny and foraging mode correspond with thiaminase activity in freshwater fishes: Potential links to environmental factors Phylogeny and foraging mode correspond with thiaminase activity in freshwater fishes: Potential links to environmental factors
Knowledge of the dietary components of fish species is important for understanding their growth, survival, and recruitment. Deficiency in thiamine (vitamin B1) leading to reproductive failure and physiological illness among freshwater fishes has been attributed to thiaminase activity in fish in the Great Lakes and the New York Finger Lakes, but the causes of variation in thiaminase...

Drought in the U.S. Caribbean:Impacts to Coastal Estuary Ecosystems Drought in the U.S. Caribbean:Impacts to Coastal Estuary Ecosystems
The topography of Puerto Rico and the U.S. Virgin Islands (USVI) is characterized by steep terrain and short distances to the sea. This means that freshwater runs off the islands quickly, coming into contact with seawater in coastal estuaries. The physical characteristics of estuaries change as the tides rise and fall, creating a wide range of habitats that support diverse plants and...

Using carbon isotope ratios to verify predictions of a model simulating the interaction between coastal plant communities and their effect on ground water salinity Using carbon isotope ratios to verify predictions of a model simulating the interaction between coastal plant communities and their effect on ground water salinity
As sea level rises in low-lying coastal islands, salt-tolerant (halophytic) coastal vegetation communities may be able to migrate inland, replacing the freshwater vegetation that is unable to tolerate salt stress. The pace of such shifts may be accelerated by a self-reinforcing feedback between the halophytic vegetation and salinity, as well as by frequent and intensified salinity pulses

Evidence of limited recruitment of Pallid Sturgeon in the Lower Missouri River Evidence of limited recruitment of Pallid Sturgeon in the Lower Missouri River
Pallid Sturgeon Scaphirhynchus albus are endemic to the Missouri and Mississippi river basins and are rare throughout their range. The species was listed as federally endangered with little to no evidence of natural recruitment. Since population augmentation was initiated as a recovery objective in the early 1990s, thousands of hatchery-origin Pallid Sturgeon have been stocked in the...

Agri-tourism and rural outdoor recreation in the US: A framework for understanding economic and employment dynamics Agri-tourism and rural outdoor recreation in the US: A framework for understanding economic and employment dynamics
Agri-tourism and rural outdoor recreation are positioned at an important intersection between agricultural, natural resource, economic development and rural issues. This chapter summarizes some of the important dynamics of these sectors, including the role of land use, regional drivers, motivations for farmers and travelers, and economic impacts. As a means to illustrate several key...

U.S. Geological Survey response to chronic wasting disease U.S. Geological Survey response to chronic wasting disease
The U.S. Geological Survey (USGS) is focused on the development of early detection and effective response tools that promote an adaptive management approach to chronic wasting disease (CWD). USGS scientists across the United States are working to understand the biology of CWD, assess and predict the spread and persistence in wildlife and the environment, and develop tools for early...

Fire severity and changing composition of forest understory plant communities Fire severity and changing composition of forest understory plant communities
Questions Gradients of fire severity in dry conifer forests can be associated with variation in understory floristic composition. Recent work in dry conifer forests in California, USA, has suggested that more severely burned stands contain more thermophilic taxa (those associated with warmer and drier conditions), and that forest disturbance may therefore accelerate floristic shifts...

Toward sustainable environmental quality: Priority research questions for North America Toward sustainable environmental quality: Priority research questions for North America
Anticipating, identifying, and prioritizing strategic needs represent essential activities by research organizations. Decided benefits emerge when these pursuits engage globally important environment and health goals, including the United Nations Sustainable Development Goals. To this end, horizon scanning efforts can facilitate identification of specific research needs to address grand...
