This book was released on 2016 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Western Brook Lamprey - Morrison Creek Population (Lampetra richardsoni), hereafter referred to as Morrison Creek Lamprey, was assessed by COSEWIC as Threatened in April 1999. In May 2000, the species' status was re-examined by COSEWIC and designated Endangered, and subsequently listed under the Species at Risk Act as Endangered in June 2003. In July of 2007 the final Recovery Strategy for the Morrison Creek Lamprey (Lampetra richardsoni var. marifuga) in Canada (NRTMCL 2007) was posted to the Species at Risk Public Registry. An updated COSEWIC assessment in 2010 confirmed the species' status as Endangered. The recovery goal as identified in the Recovery Strategy for this species is to "secure its long-term viability within its natural range." This report documents the progress of Recovery Strategy implementation for Morrison Creek Lamprey. It summarizes progress that Fisheries and Oceans Canada, the Province of British Columbia's Ministry of Environment, and other interested parties have made towards achieving the goal and objectives set out in the Recovery Strategy including: conducting new research and monitoring activities (including advancing studies to support the identification of critical habitat); and completing management activities that help Canadians reduce impacts on, and better understand the threats to, Morrison Creek Lamprey"--Executive summary.
Download or read book Making and Unmaking of Puget Sound written by Gary C. Howard and published by CRC Press. This book was released on 2022-01-27 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Puget Sound is a complex fjord-estuary system in Washington State that is connected to the Pacific Ocean by the Juan de Fuca Strait and surrounded by several large population centers. The watershed is enormous, covering nearly 43,000 square kilometers with thousands of rivers and streams. Geological forces, volcanos, Ice Ages, and changes in sea levels make the Sound a biologically dynamic and fascinating environment, as well as a productive ecosystem. Human activity has also influenced the Sound. Humans built several major cities, such as Seattle and Tacoma, have dramatically affected the Puget Sound. This book describes the natural history and evolution of Puget Sound over the last 100 million years through the present and into the future. Key Features Summarizes a complex geological, geographical, and ecological history Reviews how the Puget Sound has changed and will likely change in the future Examines the different roles of various drivers of the Sound’s ecosystem function Includes the role of humans—both first people and modern populations. Explores Puget Sound as an example of general bay ecological and environmental issues

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Western Brook Lamprey (Lampetra richardsoni), Morrison Creek population is an endangered species, endemic to the Morrison Creek watershed in Courtenay, British Columbia. Despite the risk of extinction the species is currently facing, many knowledge gaps still exist which may limit recovery or conservation efforts. Therefore, basic habitat and biological data were collected in 2021 from lamprey actively spawning in Morrison Creek to help better inform the habitat requirements for nest building and spawning. Specifically, this report documents the conditions under which lamprey were observed nest building or spawning and provides recommendations for future research"--Abstract, page v.

Book excerpt: "This document describes sampling activities and summarizes results from 2011 to 2021 trapping surveys of Morison Creek Lamprey, a unique population of Western Brook Lamprey (Lampetra richardsoni). Morrison Creek Lamprey is an endangered species at risk, present only in the Morrison Creek watershed in Courtenay, British Columbia. The trapping activities reported here not only help to monitor the population, but have also provided an opportunity to identify conservation concerns and protect the species and its habitat. The data provided in this document shows persistence of the population within its range, and should not be used as an indicator of population abundance or relative abundance"--Abstract, page vi.

Available in PDF, EPUB and Kindle. Book excerpt: "Passive downstream traps were placed in the main stem and headwaters of Morrison Creek, Courtenay, BC as a part of ongoing monitoring of Morrison Creek Lamprey, a federally-listed endangered lamprey species found only in the Morrison Creek watershed. The total numbers of lamprey trapped were low; however, they are comparable to the results of other trapping studies since 2011. Although methods are the same, catches remain much lower than those reported in the late 1970s and 1980s when the population was discovered. The causes of this decline in catch are unknown. Recommendations are to continue monitoring the population both in the main stem and headwaters through trapping studies and, using our best knowledge, ensure the habitat is maintained in a manner which supports the functions of the population and mitigates the effects of harm"--Abstract, page v.

Download or read book Conservation Biology of the Lampetra Satellite Species of Western North America with a Focus on Western Brook Lamprey L Richardsoni written by Benjamin J. Clemens and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Satellite species are composed of one parasitic lamprey that gives rise to nonparasitic lamprey species. The Lampetra satellite species of western North America are composed of three species: the anadromous Western River Lamprey (WRL) L. ayresii and two species of freshwater-resident, non-parasitic brook lampreys, the Western Brook Lamprey (WBL) L. richardsoni and Pacific Brook Lamprey (PBL) L. pacifica. The biology of these species has many information gaps, which makes assessing conservation status and identifying conservation actions challenging. We have synthesized the information from the literature to provide an understanding of the biology, threats, monitoring needs, and conservation of the Lampetra species of western North America, focusing on WBL. The three lampreys in the Lampetra satellite species, being small, exhibit relatively weak swimming abilities and undertake short movements within a water body. As such, they may be impacted by passage barriers. Whereas anadromous lampreys are predicted to migrate poleward in a changing climate, WBL and PBL will not be able to readily change their distributions, and so will likely be significantly impacted by climate change, making passage increasingly important for their conservation. Distribution monitoring and studies focused on understanding their spawning migrations and passage requirements will be essential to inform conservation"--Abstract, page v.
