This book was released on 2015 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Critical habitat is proposed for the Morrison Creek Lamprey in Morrison Creek, on Vancouver Island, British Columbia. The Morrison Creek Lamprey is currently listed as Endangered in Schedule 1 of the Species at Risk Act. The Morrison Creek Lamprey is endemic to Morrison Creek and any habitat that is critical for the survival and recovery for this species, must be afforded protection. Given the small size of the Morrison Creek drainage, the distribution of habitats for various life stages of the Morrison Creek Lamprey, the importance of consistent cold water to the continued survival of the species within the creek, and the extreme endemism of this species the critical habitat for the Morrison Creek Lamprey is recommended as the headwaters for the Morrison Creek watershed, Morrison Creek and Arden Creek in its entirety, and a riparian area of between 10 and 30 metres.

This book was released on 2004 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two fundamental aspects of lamprey biology were examined to provide tools for population assessment and determination of critical habitat needs of Columbia River Basin (CRB) lampreys (the Pacific lamprey, Lampetra tridentata, and the western brook lamprey, L. richardsoni). We evaluated the usefulness of current diagnostic characteristics for identification of larval lampreys (i.e., pigment patterns) and collected material for development of meristic and morphometric descriptions of early life stage CRB lampreys, and we determined the effects of temperature on survival and development of early life stage CRB lampreys. Thirty-one larval lampreys were collected from locations throughout the CRB and transported to the Columbia River Research Laboratory. Lampreys were sampled at six-week intervals at which time they were identified to the species level based on current diagnostic characteristics. Sampling was repeated until lampreys metamorphosed, at which time species identification was validated based on dentition, or until they died, at which time they were preserved for genetic examination. These lampreys were sampled 30 times with two individuals metamorphosing, both of which were consistently identified, and subsequently validated, as Pacific lampreys. Of the remaining lampreys, only one was inconsistently identified (Pacific lamprey in 83% of the sampling events and western brook lamprey in 17% of the sampling events). These data suggest that pigmentation patterns do not change appreciably through time. In 2001 and 2002 we artificially spawned Pacific and western brook lampreys in the laboratory to provide material for meristic and morphometric descriptions. We collected, digitized, preserved, and measured the mean chorion diameter of Pacific and western brook lamprey embryos. Embryos ranged in development from 1 d post fertilization to just prior to hatch, and were incubated at 14 C. Mean chorion diameter was greater and more variable for Pacific lampreys (mean ± SD; 1.468 ± 0.107 mm, N = 320) than for western brook lampreys (1.237 ± 0.064 mm, N = 280). An unpaired t-test showed that the difference in mean chorion diameter between species was highly significant (t = 32.788, df = 528.62, P

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.

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.
