Critical thermal maximum of stream fishes including distinct populations of Smallmouth Bass Critical thermal maximum of stream fishes including distinct populations of Smallmouth Bass
Understanding the thermal tolerances of stream fishes, including sport fishes, is important for assessing thermal stressors that are common across the landscape. Our study objectives were to determine the thermal tolerances of 17 stream fishes (15 species and 2 genetically distinct populations of juvenile Smallmouth Bass Micropterus dolomieu: the Neosho subspecies M. dolomieu velox and...

Golden eagle occupancy surveys and monitoring strategy in coastal southern California, United States Golden eagle occupancy surveys and monitoring strategy in coastal southern California, United States
Golden eagles (Aquila chrysaetos) are of increasing conservation concern in western North America. Effective conservation measures for this wide-ranging, federally protected raptor species require monitoring frameworks that accommodate strong inference on the status of breeding populations across vast landscapes. We used a broad-scale sampling design to identify relationships between...

Integrating distance sampling survey data with population indices to separate trends in abundance and temporary immigration Integrating distance sampling survey data with population indices to separate trends in abundance and temporary immigration
Managers rely on accurate estimators of wildlife abundance and trends for management decisions. Despite the focus of contemporary wildlife science on developing methods to improve inference from wildlife surveys, legacy datasets often rely on index counts that lack information about the detection process. Data integration can be a useful tool for combining index counts with data...

Estimating allowable take for an increasing bald eagle population in the United States Estimating allowable take for an increasing bald eagle population in the United States
Effectively managing take of wildlife resulting from human activities poses a major challenge for applied conservation. Demographic data essential to decisions regarding take are often expensive to collect and are either not available or based on limited studies for many species. Therefore, modeling approaches that efficiently integrate available information are important to improving...

Large-scale fire management restores grassland bird richness for a private lands ecoregion Large-scale fire management restores grassland bird richness for a private lands ecoregion
Of all terrestrial biomes, grasslands are losing the most biodiversity the most rapidly, so there is a critical need to document and learn from large-scale restoration successes. In the Loess Canyons ecoregion of the Great Plains, USA, an association of private ranchers and natural resource agencies has led a multi-decadal, ecoregion-scale initiative to combat the loss of grasslands to...

Three scleral ossicles in the West African Denticle herring Denticeps clupeoides (Clupeiformes: Denticipitidae) Three scleral ossicles in the West African Denticle herring Denticeps clupeoides (Clupeiformes: Denticipitidae)
The eyes of teleostean fishes typically exhibit two ossifications, the anterior and posterior sclerotics, both associated with the scleral cartilage. The West African Denticle herring Denticeps clupeoides has three scleral ossifications, including the typical two associated with the scleral cartilage (anterior and posterior sclerotic) and a third ossification (Di Dario's ossicle)...

Seed germination responses to salinity for three rare wetland plants of spring-fed arid systems Seed germination responses to salinity for three rare wetland plants of spring-fed arid systems
Spring-fed wetlands within arid systems host unique species of plants, many of which are threatened due to the vulnerability of these ecosystems. Increased salinity and drier hydrologic regimes due to anthropogenic activities threaten these systems. Furthermore, limited knowledge regarding key life history traits of species jeopardize the restoration and management of their rare plants...

A machine learning approach to identify barriers in stream networks demonstrates high prevalence of unmapped riverine dams A machine learning approach to identify barriers in stream networks demonstrates high prevalence of unmapped riverine dams
Restoring stream ecosystem integrity by removing unused or derelict dams has become a priority for watershed conservation globally. However, efforts to restore connectivity are constrained by the availability of accurate dam inventories which often overlook smaller unmapped riverine dams. Here we develop and test a machine learning approach to identify unmapped dams using a combination...

Similar environmental conditions are associated with Walleye and Yellow Perch recruitment success in Wisconsin lakes Similar environmental conditions are associated with Walleye and Yellow Perch recruitment success in Wisconsin lakes
Since the mid-2000s, recruitment of Walleye Sander vitreus in some northern Wisconsin lakes has declined, potentially because of climate-induced changes in lake environments. Yellow Perch Perca flavescens is also an ecologically and culturally important fish species in this region, but mechanisms driving Yellow Perch recruitment are unclear because of a lack of targeted sampling...

Differences in population characteristics and modeled response to harvest regulations in reestablished Appalachian Walleye populations Differences in population characteristics and modeled response to harvest regulations in reestablished Appalachian Walleye populations
Historically, the Monongahela, Tygart, and Cheat River watersheds in West Virginia were impaired by acidification from acid mine drainage and Walleye Sander vitreus were extirpated from these watersheds by the 1940s. Walleye were reestablished after water quality improvements following passage of environmental legislation and subsequent reintroduction efforts. We compared population

Wildfire effects on mass and thermal tolerance of Hydropsyche oslari (Trichoptera) in southwestern USA montane grassland streams Wildfire effects on mass and thermal tolerance of Hydropsyche oslari (Trichoptera) in southwestern USA montane grassland streams
Large-scale disturbances, such as wildfire, can markedly affect streams for years. As terrestrial areas within a watershed slowly recover, stream environments and biota can experience repeated and long-lasting challenges. In 2011, the Las Conchas wildfire burned 1/3 of the Valles Caldera National Preserve in northern New Mexico, USA. Seven y post-fire, streams located near the burn...

Spatial personalities: A meta-analysis of consistent individual differences in spatial behavior Spatial personalities: A meta-analysis of consistent individual differences in spatial behavior
Individual variation in behavior, particularly consistent among-individual differences (i.e., personality), has important ecological and evolutionary implications for population and community dynamics, trait divergence, and patterns of speciation. Nevertheless, individual variation in spatial behaviors, such as home range behavior, movement characteristics, or habitat use has yet to be
