Human activities create threats that have consequences for freshwater ecosystems and, in most watersheds, observed ecological responses are the result of complex interactions among multiple and their associated alterations. Here we discuss value considering research management, offer suggestions filling knowledge gaps, provide guidance addressing urgent management challenges posed by ecosystems. There is a growing literature assessing to alterations, build off this background identify three...
Abstract Decision‐makers in inland fisheries management must balance ecologically and socially palatable objectives for ecosystem services within financial or physical constraints. Climate change has transformed the potential range of available. The Resist‐Accept‐Direct (RAD) framework offers a foundation responding to climate‐induced modification; however, trajectories current practices be understood improve future decisions. Using Wisconsin's diverse as case study, strategies recreational...
Summary Stream crossing structures are an increasingly prevalent anthropogenic feature on North American riverscapes, particularly in watersheds affected by industrial resource development sensitive boreal environments. If improperly managed, stream crossings have the potential to alter fish habitat and impede movement. This study assessed instream characteristics communities from 33 culverted, bridged reference streams industrialising region of forest west‐central Alberta. Mixed‐effects...
Abstract Background Large-river decision-makers are charged with maintaining diverse ecosystem services through unprecedented social-ecological transformations as climate change and other global stressors intensify. The interconnected, dendritic habitats of rivers, which often demarcate jurisdictional boundaries, generate complex management challenges. Here, we explore how the Resist–Accept–Direct (RAD) framework may enhance large-river by promoting coordinated deliberate responses to...
The landscape theory of food web architecture (LTFWA) describes relationships among body size, trophic position, mobility, and energy channels that serve to couple heterogenous habitats, which in turn promotes long-term system stability. However, empirical tests the LTFWA are rare support differs terrestrial, freshwater, marine systems. Further, it is unclear whether applies highly altered ecosystems dominated by introduced species such as Laurentian Great Lakes. Here, we provide an test...
Abstract Nonnative fish can have substantial negative effects on the abundance and distribution of native fishes through predation competition. predators are particular interest because they represent novel threats to prey species that not adapted their presence. Prey with limited distributions or population sizes may be particularly vulnerable nonnative predators. In Laramie River, four predators—Brown Trout Salmo trutta , Rainbow Oncorhynchus mykiss Brook Salvelinus fontinalis, Smallmouth...
Abstract Climate change is a complex threat to freshwater ecosystems. Effects on aquatic species will likely differ among populations depending seasonal and spatial context, which makes detailed understanding of population responses shifting climate conditions key guiding strategic decision‐making. However, few empirical studies have tested for such context dependency distinct across seasons or at large scales. We used 26 years standardized survey data recreationally economically important...
Changing ecological conditions along environmental gradients influence patterns of biodiversity and ecosystem functioning. However, how networks interacting species respond to these changes remains unclear. We quantified aquatic food webs longitudinal stream spanning the Rocky Mountain-Great Plains ecotone using community composition, functional traits, stable isotopes. predicted that increasing size, productivity, richness gradient would positively trophic diversity (e.g., expanded vertical...
Abstract In the boreal forests of Canada, industrial development has resulted in installation thousands culverted road crossings that act as barriers to fish movement and degrade habitat for native freshwater fishes. view culvert removals being expensive, prioritisation methods have been developed, but efficacy such not thoroughly investigated nor they tested on low‐gradient forest watersheds containing at‐risk salmonids. The management utility a novel GIS‐based optimisation‐planning tool...
Abstract Food web investigations using stable isotope analyses inform management strategies by quantitatively describing interactions among species. Fin tissue is a nonlethal alternative to white muscle for obtaining ratios of fish. However, the relationship between fin and values must be evaluated before can substituted tissue. We examined relationships carbon (δ 13 C) nitrogen 15 N) in species North American freshwater fish linear regression multispecies models species‐specific models,...
Abstract Field A is a gas field located in Malaysia-Thailand Joint Development Area. As the matures after 10 years of production, number idle wells has been increasing due to various issues such as low tubing head pressure, mechanical problems and sand fill. Currently, operator embarked on an aggressive, reactivation campaign restore production through interventions. Well became January 2013 unknown reasons was selected pilot well for re-activation campaign. Tubing Retrievable – Surface...
The biological parameters needed to interpret isotopic field data on food webs — namely incorporation and discrimination (Δ 13 C Δ 15 N) are unknown for many animals. We investigated the effects of temperature carbon nitrogen in creek chub (Semotilus atromaculatus) white sucker (Catostomus commersonii) by rearing wild-caught fish a distinct diet at 12 20 °C 160 days. Mass specific growth rates were higher °C. Isotopic turnover was mainly influenced metabolic processes as opposed both...
Abstract The path to a successful graduate and research career is complex difficult one. Early researchers (ECRs) have myriad choices tasks prioritize complete as they build their CV but are often confronted with unfamiliar situations in which advice from more senior can be extremely valuable. Here, we summarize recent workshop held for ECRs by the Canadian Aquatic Resource Section of American Fisheries Society (AFS) support Education Section. Sessions touched on (1) getting published, (2)...
Freshwater biodiversity is declining from impacts associated with anthropogenic stressors. Here, we use carbon (δ 13 C) and nitrogen 15 N) stable isotopes to assess food web effects following a coal mine spill that displaced biota altered biophysical stream characteristics. We compared isotopic niche metrics of benthic macroinvertebrates the fish community, including non-native brook trout (Salvelinus fontinalis) endangered Athabasca rainbow (Oncorhynchus mykiss), infer spatial differences...
