Putting weight to work: A review and examples of weight-based indicators in freshwater fish stock assessment Putting weight to work: A review and examples of weight-based indicators in freshwater fish stock assessment
Despite being a direct measure of biomass and central to fisheries management, weight-based metrics remain underutilized in freshwater fish stock assessment. Here, we present a concise review of the application of weight in evaluating freshwater fish populations. We examine the historical use of weighing, assess how weight is applied across subdisciplines of freshwater fish science...

Colonization of southern flying squirrels (Glaucomys volans) to urban Nebraska: Range expansion or human assisted translocation? Colonization of southern flying squirrels (Glaucomys volans) to urban Nebraska: Range expansion or human assisted translocation?
Southern flying squirrels (Glaucomys volans; Linnaeus 1758) were first observed in Lincoln, Nebraska, in 2018, 80 km north of their described range. Given that southern flying squirrels are a species of concern within Nebraska, determining the origin of this new population (natural expansion or pet-trade) garnered interest from state biologists. Further, the recent colonization of...

Patterns of recent brook trout invasion in bull trout streams in relation to habitat, source connectivity, biotic resistance, and disturbance Patterns of recent brook trout invasion in bull trout streams in relation to habitat, source connectivity, biotic resistance, and disturbance
Anticipating biological invasions by nonnative species is critical to effective conservation. Nonnative brook trout Salvelinus fontinalis represents one of the most widespread threats to native bull trout Salvelinus confluentus, but the factors allowing or preventing ongoing range expansions are poorly understood. We addressed this uncertainty by resampling 221 survey locations in bull...

Melanoma and other melanistic lesions in brown bullhead Ameiurus nebulosus from waterbodies in the northeastern United States and Canada: Identification of risk factors Melanoma and other melanistic lesions in brown bullhead Ameiurus nebulosus from waterbodies in the northeastern United States and Canada: Identification of risk factors
Melanistic lesions, including non-raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada. First observed in the Vermont portion of Lake Memphremagog...

Accounting for emigration reveals high survival and bimodal size at departure from a loggerhead sea turtle (Caretta caretta) foraging area Accounting for emigration reveals high survival and bimodal size at departure from a loggerhead sea turtle (Caretta caretta) foraging area
The life history of hard-shelled sea turtles includes several ontogenetic shifts in habitat use and these complex permanent emigration patterns can impact estimates of stage-specific population rates, including survival. We developed several multistate mark recapture models to estimate survival of adult and juvenile loggerhead turtles from a coastal bay in the northern Gulf of America...

Bank-dwelling beavers contribute to the wood regime in a dryland river Bank-dwelling beavers contribute to the wood regime in a dryland river
Our findings suggest that the influence of dwelling beavers on large wood budgets may substantially determine the structure and function of medium to large rivers, particularly in dryland systems such as the White River. Recognizing the role of bank-dwelling beavers expands our understanding of biotic drivers of riverscape complexity and provides new opportunities to integrate ecology...

Cook Inlet beluga whale calling varies by group characteristics, behavior, and tidal state Cook Inlet beluga whale calling varies by group characteristics, behavior, and tidal state
Communication allows social species to exchange information among group members. In aquatic environments, acoustic signals are among the most effective forms of communication and are important for many species, including cetaceans. Beluga whales (Delphinapterus leucas) are highly social and vocal, yet little is known about the functionality of their social calls. To examine context...

Life history traits and population dynamics of Freshwater Drum across large river gradients Life history traits and population dynamics of Freshwater Drum across large river gradients
Objective Monitoring and assessment of nongame native fishes is limited, but conservation interest in these species is growing. Freshwater Drum Aplodinotus grunniens are a wide-ranging species that serve important functional roles and could serve as an indicator for similar but less common species. Our overall objectives were to quantify and compare population dynamic rates and life...

Inland recreational fisheries harvest far exceeds reported inland harvest in the United States Inland recreational fisheries harvest far exceeds reported inland harvest in the United States
Recreational fisheries are important global contributors to food security, socio-cultural practices, and local and regional economies. However, inland recreational fisheries are often overlooked by policymakers due to a limited understanding of the magnitude of participation, harvest, and economic impact. Here, we used the U.S. Inland Creel and Angler Survey Catalog and catch and effort...

Leopard occupancy and habitat use in the multi-use Chitwan-Annapurna Landscape, Nepal Leopard occupancy and habitat use in the multi-use Chitwan-Annapurna Landscape, Nepal
We estimated leopard (Panthera pardus fusca) occupancy in a multi-use region within Nepal’s Chitwan-Annapurna Landscape to evaluate leopard habitat use and inform conservation planning in areas where most of the species’ habitat occurs outside protected areas. In 2021, sign surveys were conducted along 1277 km of transects distributed among 145 grid cells of 7×7 km within a 7105 km²...

Forecasting spread of invasive fish over a largescale network of lakes using local expert knowledge Forecasting spread of invasive fish over a largescale network of lakes using local expert knowledge
Understanding spatial distribution patterns is essential to management of invasive species. Aquatic invasive species can be notably challenging to detect due to the substantial effort required to locate them underwater. This limitation has resulted in a lack of timely distribution maps, particularly over vast regions, and hindered efforts to understand, forecast, and manage the...

Geospatial assessment of agrivoltaic opportunities and land use requirements in Nigeria Geospatial assessment of agrivoltaic opportunities and land use requirements in Nigeria
Agrivoltaics, the co-location of agriculture and solar photovoltaic (PV) infrastructure, can deliver co-benefits like reduced plant drought stress and improved yields of shade-tolerant crops, particularly in water-scarce regions. Despite growing global interest, the technical potential and opportunities for agrivoltaics remain poorly understood in many regions facing both food and energy
