Abstract (from http://www.tandfonline.com/doi/full/10.1080/00028487.2016.1150879): Long-term sampling of fisheries data is an important source of information for making inferences about the temporal dynamics of populations that support ecologically and economically important fisheries. For example, time series of catch-per-effort data are often examined for the presence of long-term trends. However, it is also of interest to know whether certain sampled locations are exhibiting temporal patterns that deviate from the overall pattern exhibited across all sampled locations. Patterns at these “unusual” sites may be the result of site-specific abiotic (e.g., habitat) or biotic (e.g., the presence of an invasive species)...

Microsatellite DNA variation was examined in rainbow trout (Oncorhynchus mykiss) populations from throughout British Columbia, Canada, to address the roles of historical isolation, postglacial dispersal, and contemporary geomorphology in structuring genetic variation and differentiation. We detected signatures of historical isolation and postglacial recolonization in the form of 'interior' and 'coastal' population groupings, a decline in genetic variation as distance increased from putative glacial refugia, and different extents of isolation-by-distance in different regions. Rainbow trout populations were structured genetically into major regions and into smaller watersheds and then into drainages. Within drainages,...

Species of Concern: Fish
he George River is a tributary of the Kuskokwim River, and produces chinook salmon Oncorhynchus tshawytscha, chum salmon O. keta, and coho salmon O. kisutch that contribute to intensive subsistence and commercial salmon fisheries downstream of its confluence. The George River weir is one of several projects operated in the Kuskokwim area that form an integrated geographic array of escapement monitoring projects. Collectively, and in accordance with the State of Alaska Sustainable Fishery Policy (5 AAC 39.222), this array of projects is a tool to assure appropriate geographic and temporal distribution of spawning salmon, and provide a means to assess trends in escapement that should be monitored and considered in...

Monitoring 1-Changes in Plant and Animal Distribution: Fauna
The apparent lack of external differences between sexes, coupled with their unusual reproductive habits, make Burbot (Lota Iota Linnaeus 1758) a unique model for which to investigate life history and reproductive ecology traits. Burbot, a top level predator, are the only freshwater representative of the cod family (Gadidae). Despite being one of the most widely distributed freshwater fish species in the world, occurring throughout boreal and tundra ecosystems of the Northern Hemisphere, very little is known about their ecology. Theory suggests that life history traits develop as adaptive strategies for an organism to cope with environmental conditions. Reproduction is a key life history component, and requires tradeoffs...

During the past 30 years bull trout (Salvelinus confluentus ) populations have declined in various watersheds across their range. The decline has been attributed to loss of habitat, over harvesting, habitat disturbance from resource development activities, and interaction with exotic species. The declining population trends observed over the past three decades suggest that this species is sensitive to impacts. In response to these declines, bull trout are listed as "Threatened" in the United States and "Sensitive" in Alberta, British Columbia, and the Yukon Territory. In the Northwest Territories bull trout are listed as "May Be at Risk" and are a candidate for a detailed risk assessment in the area. The presence...

Riverine sockeye salmon Oncorhynchus nerka (those that do not use nursery lakes for juvenile rearing) tend to be characterized by greater genetic diversity and weaker population structure than lake-type populations. These findings have led to the 'recurrent evolution' hypothesis for sockeye salmon life histories, which proposes that riverine sockeye salmon are the principal colonizing form and play the dominant role in the long-term persistence of sockeye salmon in a dynamic landscape. However, previous studies in Kamchatka (Russia) and Alaska have suggested that the general patterns of riverine sockeye salmon do not apply in all parts of the species' range. In this study, we examined genetic diversity and population...
