The Conservation Opportunity Areas (COAs) for Tennessee capture populations of GCN species and high quality habitats, and as appropriate, define the geographically relevant framework for achieving conservation outcomes. The COAs currently designed for Tennessee are large geographies, with the expectation that further prioritization and goal setting for specific habitat outcomes can be achieved within them through collaborations with partners on shared objectives. While designing the COAs for Tennessee, the planning team considered three major attributes: GCN habitat priority, the problems affecting the habitats, and the on-the-ground opportunities to implement conservation actions.
The Coordinating Institution for the Species and Specimens Thematic Network is a Consortium leads by "Instituto Nacional de Biodiversidad, INBio of Costa Rica" . The members of the consortrium are: Instituto Nacional de Biodiversidad, INBio (Costa Rica) Instituto de Investigación de Recursos Biológicos Alexander von Humboldt (Colombia) (Colombia) Museo Argentino de Ciencias Naturales (Argentina) Red de Herbarios de Centroamérica y el Caribe Natureserve (USA) The goal is to implement an electronic and institutional network dedicated to regional specimen information. Some of the specimen data of any given country resides in its own museums and herbariums, although a significant part of the data resides in museums...
Intracoelomic implantation of electronic tags has become a common method in fishery research, but rarely are fish examined by scientists after release to understand the extent that surgical incisions have healed. Walleye (Sander vitreus) are a valuable, highly-exploited fishery resource in the Laurentian Great Lakes. Here, fishery capture of walleye with internal acoustic transmitters combined with a high reward program provided multiple opportunities to examine photographs and quantify the status of surgical incisions. Walleye (n=926) from reef and river spawning populations in Lake Erie and Lake Huron were implanted with acoustic transmitters during spring spawning events from 2011 to 2016. Incisions were closed...
Distribution, life history, and habitat use of bull trout ( Salvelinus confluentus) in mountain streams of the southern and central Northwest Territories
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...
Genetic Diversity and Population Structure in the Kuskokwim River Drainage Support the Recurrent Evolution Hypothesis for Sockeye Salmon Life Histories
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...
