This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Vancouver Island marmot (Marmota vancouverensis) is an endangered mammal whose population is being recovered with a conservation breeding and release program. This involves management both in and ex situ, so it is vital to understand how the different environments are affecting the populations to maximize program outcomes. The purpose of this thesis was to retrospectively analyze data collected from this program to address questions relevant to population recovery. The first chapter compared the physiology of the managed populations using the neutrophil: lymphocyte ratio and found significant differences in this metric among targeted comparisons. The second chapter assessed factors that may be contributing to hibernation-related mortality of marmots during their first winter post-release. I found a combination of environmental and intrinsic factors influencing this mortality. Overall, this thesis contributes to a growing body of literature surrounding the efficacy of conservation breeding and release programs to recover critically endangered species.

Available in PDF, EPUB and Kindle. Book excerpt: We estimated age-specific reproductive parameters and used various age-specific survival rates spanning different periods of time and/or representing various subsets of the population. We found that population growth rate in recent years (2003-2008) was only slightly higher than in the past (1987-2002), and currently the population is still declining by at least 12% annually. The population growth rate estimated for a hypothetical population of captive-born marmots corresponds with a 28% decline annually, indicating released individuals alone will not result in a persistent population. However, population growth rate for a population of wild-born individuals in recent years was greater than one, indicating a 3% annual increase in population size. Elasticity analysis confirmed the relative importance of survival for the population, especially adult survival. Our results provide insight into the potential for recovery of the species through reintroductions.

This book was released on 2004 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: "... We identified the hoary marmot (Marmota caligata) as an "ecological surrogate" for research into the recovery of the Vancouver Island Marmot (VIM) (Marmota vancouverensis) based on the high degree of relatedness and similarities in behaviour and ecology between the two species. Our aim was to understand, in detail, the natural ecological processes that influence population dynamics in a healthy population of social alpine dwelling marmots. ... Our study on hoary marmots demonstrated that their population persistence is determined by climate variability and social behaviour. Reproduction in adult females and survival of pups was closely coupled with annual changes in environmental conditions. Changing snowpack conditions can alter the efficiency at which marmots can hibernate and can also alter their access to food in the spring. Hoary marmot populations are quite robust to extreme variation in climatic conditions but stability is greater in a cyclic climate, which is influenced by the Pacific North American Pattern (PNA). Persistence of hoary marmot population is greatly influenced by their social behaviour. Young marmots delay dispersal beyond their age of reproductive maturity (3 years old), sometimes for several years without reproducing within their birth social group. Retaining subadults (male and female) within a social group has a profound effect on the survival of pups with the odds of survival increasing by a factor of 1.4 for every subadult retained within the social group. VIM populations are also relatively robust to large fluctuations in annual weather conditions. However, based on the demography within clearcuts, populations living in a habitat matrix of clearcuts and alpine have a lowered probability of persistence than if all colonies live only in natural alpine habitat. Furthermore, the Allee effect may be the greatest challenge to the recovery and persistence of VIM. The degree of sociality within VIM are unknown, but we do know that they are highly social, live in family groups and that they socially hibernate, all of which is consistent with our observations in hoary marmots. Therefore, the possibility of an Allee effect for VIM is great and we suggest it is possible that the Allee effect may possibly operate through other mechanisms (i.e. predation). However, this effect may still be detrimental to the recovery and persistence of their populations. The effect of food supplementation on the reproductive fitness of adult female marmots is still inconclusive. The evidence we have so far suggest that the effects of food supplementation may be delayed and positive effects are stronger in more stressful spring conditions. In more stressful years, pups born to supplemented females can be 60% larger than control pups. We have yet to determine if this mass increase provides an advantage to survival during hibernation." -- ASTIS [online] bibliography.
