Book excerpt: Mountain goats have been among the least studied of North American ungulates, leaving wildlife managers with little information on which to base harvest strategies or conservation plans. This book offers the first comprehensive assessment of the ecology and behavior of mountain goats, setting forth the results of a remarkable 16-year longitudinal study of more than 300 marked individuals in a population in Alberta, Canada. The authors’ thorough, long-term study allowed them to draw important conclusions about mountain goat ecology—including individual reproductive strategies, population dynamics, and sensitivity to human disturbance—and to use those conclusions in offering guidance for developing effective conservation strategies. Chapters examine: -habitat use, vegetation quality, and seasonal movements -sexual segregation and social organization -individual variability in yearly and lifetime reproductive success of females -age- and sex-specific survival and dispersal -reproductive strategies and population dynamics -management and conservation of mountain goats The book also draws on the rich literature on long-term monitoring of marked ungulates to explore similarities and differences between mountain goats and other species, particularly bighorn sheep and ibex. By monitoring a marked population over a long period of time, researchers were able to document changes in sex-age structure and identify factors driving population dynamics. Because it explores the links between individual life-history strategy and population dynamics in a natural setting, Mountain Goats will be an invaluable resource for wildlife managers, researchers in ecology and animal behavior, conservationists, population biologists, and anyone concerned with the ecology and management of natural populations, especially in alpine environments.

Book Synopsis Fine-scale Habitat Selection and Space Use by Mountain Goats (Oreamnos Americanus) by : Adam Gerhard Wells

This book was released on 2012 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current application of GPS telemetry in wildlife studies highlights the need for analytical methods to meet theoretical concerns during analysis of resource selection. I devised a new analysis technique for estimation of resource selection, the Brownian bridge synoptic model. Availability is based on the variance term from the existing Brownian bridge model, and maximum likelihood is used to estimate resource selection based on the existing synoptic model. The analysis separates the observed GPS data into triplets of observation and estimates probability of use at every other GPS location thereby. To test the model, I analyzed GPS data collected from free-ranging mountain goats Oreamnos americanus in the Cascade Mountains, Washington, where patterns of habitat selection were relatively unknown. I also conducted field reconnaissance and identified 8 vegetation communities across mountain goat home ranges: montane forest, subalpine forest, heather, huckleberry, east-side shrub, sparse meadow, dense meadow and talus. I linked the results of the field work to three LandSat 5TM scenes to create a map of vegetation communities. I used the vegetation map with the Brownian bridge synoptic model to evaluate patterns of habitat selection by mountain goats during late spring through early summer in response to the presence of potential forage items. Additionally, I used the Brownian bridge synoptic model, ordinary logistic regression, and the synoptic model to test patterns of habitat selection by mountain goats in response to backcountry trails. I used an information theoretic approach and compared the results of model selection at multiple scales approximating third and fourth orders of selection. I estimated habitat selection for individual animals and developed overall and sex specific population averages. Results showed topography as the primary determinant of selection by mountain goats with male mountain goats using steeper areas further from both escape terrain and trails than females. I found little evidence to suggest habitat selection by mountain goats was influenced by vegetation. Finally, I used the Brownian bridge synoptic model to address a management question concerning translocations and produced a resource selection function to evaluate potential release sites.

Book excerpt: A 70-90% decline in mountain goat (Oreamnos americanus) populations in Washington State over the past few decades has spurred the need for an improved understanding of seasonal goat-habitat relationships. Habitat use data have been collected from 46 radio-collared mountain goats across their native range in Washington State. Using Geographical Information Systems (GIS), I explored relationships between use and availability of habitat. To overcome issues of autocorrelation, I compared actual mountain goat paths with available paths of matched identical spatial topology and used multi-scale path analysis to explore various ecologically informed relationships between landscape structure and the movements of mountain goats at the home range scale. I extracted used and available (randomized) paths at 4 scales of analysis using square extraction windows of 0.06, 4.4, 15.2, and 56.2 ha that were centered on each point along the path. Matched case logistic regression allowed me to determine the spatially and temporally explicit scales that were the strongest predictors of seasonal and year-round mountain goat habitat from a suite of predictor variables. I found that for year-round habitat, mountain goats chose both abiotic and biotic components of their landscape including; parkland, areas of high solar loading, terrain that is rugged, and terrain that allows escape from predators. This analysis represents one of the most extensive landscape-level habitat relationship studies conducted on mountain goats. Additionally, my methodological approach is applicable to other species-habitat association analyses.

Book excerpt: Les changements climatiques ont un impact sur la biosphère, causant notamment des extinctions d'espèces, des changements d'aire de répartition, des effondrements d'écosystèmes et des modifications de comportement. Ces impacts sont susceptibles d'être exacerbés à mesure que les changements climatiques continuent de s'accélérer. Pour prédire les impacts des changements projetés sur la faune, nous devons comprendre comment la météo influence le comportement des espèces. En Amérique du Nord, les précipitations et la température devraient augmenter au cours des prochaines décennies, en particulier aux latitudes et altitudes élevées. Les chèvres de montagne (Oreamnos americanus), comme de nombreux ongulés nordiques, risquent d'être affectées négativement par des températures estivales plus chaudes. Le but de mon projet est de comprendre comment les conditions environnementales estivales influencent le comportement et la sélection d'habitats des chèvres de montagne afin de mieux comprendre les impacts futurs des changements climatiques. Nous avons émis l'hypothèse que les températures estivales élevées incitent les chèvres de montagne à utiliser des tactiques d'évitement de la chaleur telles que l'utilisation de microsites frais (haute altitude, zones boisées, microsites enneigés et habitats ombragés) et à réduire leur activité pendant la période la plus chaude de la journée. Nous avons également émis l'hypothèse que les tactiques d'évitement de la chaleur utilisées par les chèvres dans les environnements côtiers et continentaux sont différentes, les chèvres en milieu côtier utilisant des altitudes plus élevées lorsque la température augmente et les chèvres en milieu continental utilisant des zones boisées et ombragées. Nous avons analysé l'influence des conditions météorologiques estivales, en particulier la température, sur les modèles d'activité et la sélection de l'habitat de quatre populations de chèvres de montagne représentant les deux écotypes observés chez cette espèce, côtier et continental. Les chèvres de montagne des deux écotypes ont utilisé des tactiques différentes pour éviter la chaleur dans leur sélection d'habitats. Les chèvres de montagne des milieux côtiers ont sélectionné des habitats ouverts proche de la neige, tandis que les chèvres des sites continentaux ont sélectionné les milieux forestiers lorsque la température augmentait. Les chèvres de montagne dans les environnements continentaux ont choisi des habitats à plus haute altitude plus souvent que ceux en basse altitude uniquement lorsque la température augmentait, tandis que les chèvres dans les environnements côtiers ont choisi des habitats à plus haute altitude à toutes les températures. Les chèvres de montagne des deux écotypes ont réduit leur proportion de temps passé actif lorsque les températures augmentaient au milieu de la journée, mais l'activité à l'aube et au crépuscule n'était pas influencée par la température. Notre étude montre que les chèvres de montagne utilisent une série de tactiques différentes pour éviter le stress thermique. Nous montrons également que les chèvres de montagne vivant dans différents écosystèmes utilisent des tactiques alternatives et sont affectées par le changement climatique de manière différente. Nos résultats soulignent l'importance d'évaluer l'impact des changements climatiques au niveau de la population plutôt qu'au niveau de l'espèce, car les espèces ne sont pas un assemblage homogène de populations et les populations subissent des contraintes environnementales différentes selon le milieu qu'elles habitent.
