Interactive effects of food supplementation and snake fungal disease on pregnant Pygmy Rattlesnakes and their offspring Interactive effects of food supplementation and snake fungal disease on pregnant Pygmy Rattlesnakes and their offspring
In viviparous organisms, the ability to feed while pregnant may mitigate energetic trade-offs experienced during the reproductive process and enhance fecundity. However, anorexia during pregnancy has been reported in many crotaline snakes. The potential costs and benefits of feeding while pregnant are not completely described in the literature, and experimental studies have been...

Applying the ecology of aquatic–terrestrial linkages to freshwater and riparian management Applying the ecology of aquatic–terrestrial linkages to freshwater and riparian management
Global stressors such as climate change, invasive species, urbanization, agricultural practices, and pollution can alter aquatic resource subsidies to terrestrial consumers. The effects of these stressors on timing, quality, and quantity of aquatic subsidies, such as adult aquatic insects, to birds, herpetofauna, and mammals, have large implications for wildlife management (Baxter et al...

Genomic pedigree reconstruction identifies predictors of mating and reproductive success in an invasive vertebrate Genomic pedigree reconstruction identifies predictors of mating and reproductive success in an invasive vertebrate
The persistence of an invasive species is influenced by its reproductive ecology, and a successful control program must operate on this premise. However, the reproductive ecology of invasive species may be enigmatic due to factors that also limit their management, such as cryptic coloration and behavior. We explored the mating and reproductive ecology of the invasive Brown Treesnake (BTS...

Examining progress toward achieving the Ten Steps of the Rome Declaration on Responsible Inland Fisheries Examining progress toward achieving the Ten Steps of the Rome Declaration on Responsible Inland Fisheries
Inland capture fisheries provide food for nearly a billion people and are important in the livelihoods of millions of households worldwide. Although there are limitations to evaluating many of the contributions made by inland capture fisheries, there is growing recognition by the international community that these services make critical contributions, most notably to food security and...

Effects of ocean climate on the length and condition of forage fish in the Gulf of Alaska Effects of ocean climate on the length and condition of forage fish in the Gulf of Alaska
Climatic drivers of the size and body condition of forage fish in the North Pacific are poorly known. We hypothesized that length and condition of forage fish in the Gulf of Alaska (GoA) should vary in relation to ocean temperature on multiple scales. To test this hypothesis, we analyzed morphometric data for capelin (Mallotus catervarius) and Pacific sand lance (PSL; Ammodytes...

In vitro immune function in laboratory-reared age-0 smallmouth bass (Micropterus dolomieu) relative to diet In vitro immune function in laboratory-reared age-0 smallmouth bass (Micropterus dolomieu) relative to diet
Smallmouth bass (Micropterus dolomieu) are used as an indicator species in environmental monitoring and assessment studies. However, laboratory-based studies for methods development and effector assessment are limited for this species. Nutrition, a known modulator of teleost physiological responses including immune function, is a critical knowledge-gap sometimes overlooked in the design...

Wetland biomass and productivity in Coastal Louisiana: Base line data (1976-2015) and knowledge gaps for the development of spatially explicit models for ecosystem restoration and rehabilitation initiatives Wetland biomass and productivity in Coastal Louisiana: Base line data (1976-2015) and knowledge gaps for the development of spatially explicit models for ecosystem restoration and rehabilitation initiatives
Coastal Louisiana host 37% of the coastal wetland area in the conterminous US, including one of the deltaic coastal regions more susceptible to the synergy of human and natural impacts causing wetland loss. As a result of the construction of flood protection infrastructure, dredging of channels across wetlands for oil/gas exploration and maritime transport activities, coastal Coastal...

Assessing spatial and temporal patterns in sagebrush steppe vegetation communities 2012-2018: Grand Teton National Park Assessing spatial and temporal patterns in sagebrush steppe vegetation communities 2012-2018: Grand Teton National Park
Visual cover class data were collected on over 80 species across 30 permanent sampling frames in sagebrush steppe vegetation communities in Grand Teton National Park from 2012 to 2018. In this report, temporal and spatial patterns in species composition were assessed and used to inform potential sampling strategies for future monitoring. Specifically, the viability of a reduction in...

Using oblique imagery to measure hypsometric changes in sandbar volume following controlled floods in the Grand Canyon Using oblique imagery to measure hypsometric changes in sandbar volume following controlled floods in the Grand Canyon
Measuring changes in the elevation distribution of sub-aerial fine ( 2 mm ) sediment and estimating sandbar volume multiple times per year can improve sediment budget calculations in fluvial systems. In the Grand Canyon of the Colorado River, effects of dam operations on sandbar size and distribution is of long-term management interest. Bar-building controlled floods have been...

Environmental DNA (eDNA) detection of nonnative bullseye snakehead in southern Florida Environmental DNA (eDNA) detection of nonnative bullseye snakehead in southern Florida
Bullseye Snakehead Channa marulius (Hamilton 1822) was first detected in the southern Florida town of Tamarac in 2000 and has been expanding its geographic range since. Environmental DNA (eDNA) analysis is a newly-developed technique used to noninvasively detect cryptic or low-density species or those that are logistically difficult-to-study. Genetic material shed into the environment...

Framework for monitoring shrubland community integrity in California Mediterranean type ecosystems: Information for policy makers and land managers Framework for monitoring shrubland community integrity in California Mediterranean type ecosystems: Information for policy makers and land managers
Shrublands in Mediterranean‐type ecosystems worldwide support important ecosystem services including high levels of biodiversity and are threatened by multiple factors in heavily used landscapes. Use, conservation, and management of these landscapes involve diverse stakeholders, making decision processes complex. To be effective, management and land use decisions should be informed by...

Restoration of Lake Trout in Lake Superior through Interagency Cooperative Management Restoration of Lake Trout in Lake Superior through Interagency Cooperative Management
The lake trout is a keystone species in the Laurentian Great Lakes that supported valuable fisheries throughout the basin. However, lake trout populations declined to near extirpation in nearly all of the lakes because of the combined effects of over-fishing, sea lamprey predation, and habitat degradation. To restore self-sustaining lake trout populations in Lake Superior, state...
