Avian response to fire in pine–oak forests of Great Smoky Mountains National Park following decades of fire suppression Avian response to fire in pine–oak forests of Great Smoky Mountains National Park following decades of fire suppression
Fire suppression in southern Appalachian pine–oak forests during the past century dramatically altered the bird community. Fire return intervals decreased, resulting in local extirpation or population declines of many bird species adapted to post-fire plant communities. Within Great Smoky Mountains National Park, declines have been strongest for birds inhabiting xeric pine–oak forests...

Salinity effects on plasma ion levels, cortisol, and osmolality in Chinook salmon following lethal sampling Salinity effects on plasma ion levels, cortisol, and osmolality in Chinook salmon following lethal sampling
Studies on hydromineral balance in fishes frequently employ measurements of electrolytes following euthanasia. We tested the effects of fresh- or salt-water euthanasia baths of tricaine mesylate (MS-222) on plasma magnesium (Mg2+) and sodium (Na+) ions, cortisoland osmolality in fish exposed to saltwater challenges, and the ion and steroid hormone fluctuations over time following...

Predicting thermally stressful events in rivers with a strategy to evaluate management alternatives Predicting thermally stressful events in rivers with a strategy to evaluate management alternatives
Water temperature is an important factor in river ecology. Numerous models have been developed to predict river temperature. However, many were not designed to predict thermally stressful periods. Because such events are rare, traditionally applied analyses are inappropriate. Here, we developed two logistic regression models to predict thermally stressful events in the Delaware River at...

Population dynamics and evaluation of alternative management strategies for nonnative Lake Trout in Priest Lake, Idaho Population dynamics and evaluation of alternative management strategies for nonnative Lake Trout in Priest Lake, Idaho
Lake Trout Salvelinus namaycush have been introduced widely throughout the western USA to enhance recreational fisheries, but high predatory demand can create challenges for management of yield and trophy fisheries alike. Lake Trout were introduced to Priest Lake, Idaho, during the 1920s, but few fishery-independent data are available to guide current or future management actions. We...

Global perspectives on the urban stream syndrome Global perspectives on the urban stream syndrome
Urban streams commonly express degraded physical, chemical, and biological conditions that have been collectively termed the “urban stream syndrome”. The description of the syndrome highlights the broad similarities among these streams relative to their less-impaired counterparts. Awareness of these commonalities has fostered rapid improvements in the management of urban stormwater for...

Using standardized fishery data to inform rehabilitation efforts Using standardized fishery data to inform rehabilitation efforts
Lakes and reservoirs progress through an aging process often accelerated by human activities, resulting in degradation or loss of ecosystem services. Resource managers thus attempt to slow or reverse the negative effects of aging using a myriad of rehabilitation strategies. Sustained monitoring programs to assess the efficacy of rehabilitation strategies are often limited; however, long...

Assessing models of speciation under different biogeographic scenarios; An empirical study using multi-locus and RNA-seq analyses Assessing models of speciation under different biogeographic scenarios; An empirical study using multi-locus and RNA-seq analyses
Evolutionary biology often seeks to decipher the drivers of speciation, and much debate persists over the relative importance of isolation and gene flow in the formation of new species. Genetic studies of closely related species can assess if gene flow was present during speciation, because signatures of past introgression often persist in the genome. We test hypotheses on which...

The relative influence of road characteristics and habitat on adjacent lizard populations in arid shrublands The relative influence of road characteristics and habitat on adjacent lizard populations in arid shrublands
As road networks continue to expand globally, indirect impacts to adjacent wildlife populations remain largely unknown. Simultaneously, reptile populations are declining worldwide and anthropogenic habitat loss and fragmentation are frequently cited causes. We evaluated the relative influence of three different road characteristics (surface treatment, width, and traffic volume) and...

Urbanization and stream ecology: Diverse mechanisms of change Urbanization and stream ecology: Diverse mechanisms of change
The field of urban stream ecology has evolved rapidly in the last 3 decades, and it now includes natural scientists from numerous disciplines working with social scientists, landscape planners and designers, and land and water managers to address complex, socioecological problems that have manifested in urban landscapes. Over the last decade, stream ecologists have met 3 times at the...

Northern long-eared bat day-roosting and prescribed fire in the Central Appalachians, USA Northern long-eared bat day-roosting and prescribed fire in the Central Appalachians, USA
The northern long-eared bat (Myotis septentrionalis Trovessart) is a cavity-roosting species that forages in cluttered upland and riparian forests throughout the oak-dominated Appalachian and Central Hardwoods regions. Common prior to white-nose syndrome, the population of this bat species has declined to functional extirpation in some regions in the Northeast and Mid-Atlantic, including...

Characterizing seasonal and diel vertical movement and habitat use of lake whitefish (Coregonus clupeaformis) in Clear Lake, Maine Characterizing seasonal and diel vertical movement and habitat use of lake whitefish (Coregonus clupeaformis) in Clear Lake, Maine
Seasonal and daily vertical activity of lake whitefish Coregonus clupeaformis was studied in Clear Lake, Maine (253 ha), using acoustic telemetry from November 2004 to June 2009. Twenty adult lake whitefish were tagged with acoustic tags that had either a depth sensor or both depth and temperature sensors to assess vertical habitat use at a seasonal and daily resolution. Vertical habitat...

Toward more realistic projections of soil carbon dynamics by Earth system models Toward more realistic projections of soil carbon dynamics by Earth system models
Soil carbon (C) is a critical component of Earth system models (ESMs), and its diverse representations are a major source of the large spread across models in the terrestrial C sink from the third to fifth assessment reports of the Intergovernmental Panel on Climate Change (IPCC). Improving soil C projections is of a high priority for Earth system modeling in the future IPCC and other...
