Availability and timing of fathead minnow supplementation influence largemouth bass survival and production in rearing ponds Availability and timing of fathead minnow supplementation influence largemouth bass survival and production in rearing ponds
Adjustments to rearing practices should be justified with increases in production, stocking success, or angler satisfaction. Largemouth bass (Micropterus salmoides) production was assessed between hatchery ponds where fish were restricted to an invertebrate diet or received supplemental fathead minnow (Pimephales promelas) forage during 2015. At harvest, age-0 bass yield was 4.5 times...

Decision analysis for greater insights into the development and evaluation of Chinook salmon restoration strategies in California’s Central Valley Decision analysis for greater insights into the development and evaluation of Chinook salmon restoration strategies in California’s Central Valley
Considerable amounts of resources have been invested in ecological restoration projects across the globe to restore ecosystem integrity. Restoration strategies are often diverse and have been met with mixed success. In this paper, we describe the Chinook salmon (Oncorhynchus tshawytscha) decision-support models developed by the Central Valley Project Improvement Act Science Integration...

Trends in inland commercial fisheries in the United States Trends in inland commercial fisheries in the United States
Inland fisheries, defined as finfish caught in lakes, rivers, and other water bodies, provide economic value and a source of protein at local and international levels. However, no comprehensive compilation of U.S. inland commercial fisheries exists. We sought to obtain data across all 50 states during 1990–2015 and noted a small, but significant, decline in harvest. The minimum harvest...

Bot fly parasitism of Allegheny woodrats (Neotoma magister) in Virginia Bot fly parasitism of Allegheny woodrats (Neotoma magister) in Virginia
The Allegheny woodrat (Neotoma magister) is a species of high conservation concern and relatively well-studied with respect to habitat use/associations, food habits, conservation genetics, and population trends. However, with the exception of raccoon roundworm (Baylisascaris procyonis) occurrence and etiology in woodrats, most disease and parasite ecology aspects for the woodrat are...

A GT-seq panel for walleye (Sander vitreus) provides important insights for efficient development and implementation of amplicon panels in non-model organisms A GT-seq panel for walleye (Sander vitreus) provides important insights for efficient development and implementation of amplicon panels in non-model organisms
Targeted amplicon sequencing methods, such as genotyping-in-thousands by sequencing (GT-seq), facilitate rapid, accurate, and cost-effective analysis of hundreds of genetic loci in thousands of individuals. Development of GT-seq panels is nontrivial, but studies describing trade-offs associated with different steps of GT-seq panel development are rare. Here, we construct a dual-purpose...

Assessing the vulnerability of military installations in the coterminous United States to potential biome shifts resulting from rapid climate change Assessing the vulnerability of military installations in the coterminous United States to potential biome shifts resulting from rapid climate change
Climate change impacts to Department of Defense (DoD) installations will challenge future military mission and natural resource stewardship efforts by increasing vulnerability to flooding, drought, altered fire regimes, invasive species, etc. We developed biome classifications based on current climate for the coterminous United States using the Holdridge Life Zone system to assess...

Benthic suffocation of invasive lake trout embryos by fish carcasses and sedimentation in Yellowstone Lake Benthic suffocation of invasive lake trout embryos by fish carcasses and sedimentation in Yellowstone Lake
Introduced Lake Trout Salvelinus namaycush threaten native Yellowstone Cutthroat Trout Oncorhynchus clarkii bouvieri in Yellowstone Lake, Yellowstone National Park, where gill nets have been used to suppress subadult and adult Lake Trout since 1995. However, survival of embryonic and larval life history stages can have profound effects on the population dynamics of Lake Trout. Inducing...

Using a structured decision analysis to evaluate bald eagle vital signs monitoring in Southwest Alaska National Parks Using a structured decision analysis to evaluate bald eagle vital signs monitoring in Southwest Alaska National Parks
1. Monitoring programs can benefit from an adaptive monitoring approach, where key decisions about why, where, what, and how to monitor are revisited periodically in order to ensure programmatic relevancy. 2. The National Park Service (NPS) monitors status and trends of Vital Signs to evaluate compliance with the NPS mission. Although abundant, The Southwest Alaska Network (SWAN)...

Extreme drought and adaptive resource selection by a desert mammal Extreme drought and adaptive resource selection by a desert mammal
When animals select areas to occupy, decisions involve trade-offs between the fitness benefits of obtaining critical resources and minimizing costs of biotic and abiotic factors that constrain their use. These processes can be more dynamic and complex for species inhabiting desert environments, where highly variable spatial and temporal distribution of precipitation can create high intra...

Indexing age-0 Walleye abundance in northern Wisconsin lakes Before fall Indexing age-0 Walleye abundance in northern Wisconsin lakes Before fall
Age-0 Walleye Sander vitreus recruitment is often indexed using fall electrofishing surveys. However, collecting fish before fall may provide timely information regarding stocking decisions and factors influencing recruitment. We evaluated sampling methods for age-0 Walleye in northern Wisconsin lakes that could be used to assess recruitment in spring and summer. Initial assessments on...

Wave-like patterns of plant phenology determine ungulate movement tactics Wave-like patterns of plant phenology determine ungulate movement tactics
Animals exhibit a diversity of movement tactics [1]. Tracking resources that change across space and time is predicted to be a fundamental driver of animal movement [2]. For example, some migratory ungulates (i.e., hooved mammals) closely track the progression of highly nutritious plant green-up, a phenomenon called “green-wave surfing” [3-5]. Yet, general principles describing how the...
