Reducing uncertainty in climate change responses of inland fishes: A decision-path approach Reducing uncertainty in climate change responses of inland fishes: A decision-path approach
Climate change will continue to be an important consideration for conservation practitioners. However, uncertainty in identifying appropriate management strategies, particularly for understudied species and regions, constrains the implementation of science-based solutions and adaptation strategies. Here, we share a decision-path approach to reduce uncertainty in climate change responses...

Association of antler asymmetry with hoof disease in elk Association of antler asymmetry with hoof disease in elk
Treponeme-associated hoof disease (TAHD) is an emergent disease of elk (Cervus canadensis) in the Pacific West of the United States. Although lesions are usually restricted to the feet, anecdotal reports suggested increased prevalence of abnormal antlers in affected elk. We used hunter harvest reports for 1,688 adult male elk harvested in southwestern Washington, USA, during 2016-2018...

The importance of lake emergent aquatic vegetation for estimating Arctic-boreal methane emissions The importance of lake emergent aquatic vegetation for estimating Arctic-boreal methane emissions
Areas of lakes that support emergent aquatic vegetation emit disproportionately more methane than open water but are under-represented in upscaled estimates of lake greenhouse gas emissions. These shallow areas are typically less than ∼1.5 m deep and can be detected with synthetic aperture radar (SAR). To assess the importance of lake emergent vegetation (LEV) zones to landscape-scale...

Worldwide wetland loss and conservation of biodiversity and ecosystem services Worldwide wetland loss and conservation of biodiversity and ecosystem services
Aim: Best strategies for future conservation and management to address global and regional trends in wetland loss and degradation are assessed in this article. Main concepts covered: Direct drivers of wetland loss and change include land drainage and filling, hydrologic alteration, degradation from pollutants and sediments, and conversion to agriculture, urban and industrial usage...

Wetlands under global change Wetlands under global change
Wetlands are among the ecosystem types most threatened by global change, including both climate change and other anthropogenic factors such as sea level rise, urban development, deforestation, agricultural land use, drainage, levees, tidal flow restrictions, pollution, eutrophication, and fires. Wetlands not only store disproportionate amounts of carbon compared to other terrestrial...

Societal values of inland fishes Societal values of inland fishes
a. Aim: To demonstrate the societal values of inland fishes through nine services provided by inland fishes. Each service is defined, key stakeholders identified, and threats enumerated. Diverse case studies (geography, taxonomy, fishery-type) provide examples to highlight the societal values around the world. b. Main concepts: Nine societal services of inland fishes – 1. Livelihoods and...

Intrapopulation differences in polar bear movement and step selection patterns Intrapopulation differences in polar bear movement and step selection patterns
Background The spatial ecology of individuals often varies within a population or species. Identifying how individuals in different classes interact with their environment can lead to a better understanding of population responses to human activities and environmental change and improve population estimates. Most inferences about polar bear (Ursus maritimus) spatial ecology are based on...

Environmental drivers of cyanobacterial abundance and cyanotoxin production in backwaters of the Upper Mississippi River Environmental drivers of cyanobacterial abundance and cyanotoxin production in backwaters of the Upper Mississippi River
High densities of cyanobacteria in aquatic ecosystems can cause impacts to ecosystem services because they serve as a poor-quality food resource, produce toxins and can indirectly cause a variety of other negative impacts to water quality. There are many hypotheses about the potential environmental drivers of variation in cyanobacterial abundance and toxicity, but these hypotheses have...

Cryptic extinction risk in a western Pacific lizard radiation Cryptic extinction risk in a western Pacific lizard radiation
Cryptic ecologies, the Wallacean Shortfall of undocumented species’ geographical ranges and the Linnaean Shortfall of undescribed diversity, are all major barriers to conservation assessment. When these factors overlap with drivers of extinction risk, such as insular distributions, the number of threatened species in a region or clade may be underestimated, a situation we term ‘cryptic...

Influences of seasonality and habitat quality on Great Lakes coastal wetland fish community composition and diets Influences of seasonality and habitat quality on Great Lakes coastal wetland fish community composition and diets
Great Lakes coastal wetlands (GLCW) have been severely degraded by anthropogenic activity over the last several decades despite their critical role in fish production. Many Great Lakes fish species use coastal wetland habitats for spawning, feeding, shelter, and nurseries throughout the year. The goal of our study was to compare GLCW fish community composition in the spring, summer, and...

Comparison of indices to infer population dynamics of black brant Comparison of indices to infer population dynamics of black brant
To aid managers in assessing status of Pacific black brant Branta bernicla nigricans (hereafter brant), I examined pre-existing long-term data series from summer, fall staging, and wintering areas to infer overall population processes and assessed the utility of the various data sources. Variation in demographic parameters measured in subarctic and Arctic locations suggests some form of

Value of information and decision pathways: Concepts and case studies Value of information and decision pathways: Concepts and case studies
Information used in decision making arises from the structuring of observations and data. The collection, dissemination, and use of information has monetary and non-monetary costs (e.g., competition for attention) and necessitates trade-offs. Understanding the benefits of having information (i.e., the value of information, VOI), including resulting societal outcomes, is useful to...
