The submerged and floating plant communities in floodplain wetlands of the Upper Columbia River have never been described. To explore mechanisms behind influence annual flood pulse on vegetation, we investigated how species group into response guilds whose distributions vary along a connectivity gradient between 44 river, influences water sediment, to what degree effect vegetation is mediated by its effects these environmental variables. We characterised assemblages with cluster indicator...
ABSTRACT Objective Numerous populations of Pacific salmon have experienced decreased abundance and body size in the past 50 years. Ni’iinlii Njik (Fishing Branch River) northern Yukon is natal stream to largest population Chum Salmon Oncorhynchus keta Canada. For over years, total spawner abundance, age, sex fork length data were collected from thousands spawning Salmon. We asked whether there systematic changes length, ratio this time frame. Methods Age, sex, sampled 23,906 Salmon, was...
Floodplain wetlands in the upper Columbia River valley are governed by flood pulse. Water flows from river into adjacent through channels incised levees or over top of levees. This floodplain is relatively pristine with few road crossings restricting flow water a 110 km length floodplain. We describe vegetation at three points 60 years to detect natural changes and contrast that downstream roads transecting wetlands. mapped eight landscape cover types within 40 floodbasins four 2 sections...
Statistical stream temperature models predicting the fine-scale spatial distribution of water temperatures (i.e., “thermalscape”) can guide aquatic species recovery and habitat restoration efforts. However, modelling is complicated by autocorrelation arising from non-independence sampling sites within dendritic networks. We used August mean data miniature sensors deployed in Canadian Rocky Mountain streams to demonstrate two statistical techniques that account for autocorrelation. The first...
Abstract The intentional introduction of native cold‐water trout into high‐elevation fishless lakes has been considered a tool to build resilience climate change (i.e., assisted colonization); however, ecological impacts on recipient communities are understudied. purpose this study was inform recovery managers by assessing potential consequences translocating regionally (westslope cutthroat trout; Oncorhynchus clarkii lewisi ) mountain lakes. This compared littoral benthic invertebrate...
Abstract Dams represent one of the major forms river alteration. As these structures reach end their lifespan, they often require extensive refurbishments or removal. A small‐scale water supply dam in Banff National Park (Alberta, Canada) was partially removed, creating a breach that allowed to scour new passage resembling nature‐like fishway. We investigated permeability removed as means validating conservation benefits partial quantified proportion bull trout ( Salvelinus confluentus ),...
Abstract Background Fixed radio telemetry stations are used to study the movement ecology of fishes in streams and rivers. A common assumption such studies is that detection efficiency remains constant through space time. The objective this was understand how site characteristics tag distance can influence a fixed receiver when for fisheries research small stream. Field tests included station on Forty Mile Creek, Banff National Park, AB, Canada recorded signals from tags over specified...
