Concerns over possible numeric declines and a paucity of baseline data on moose in the state prompted the Utah Division of Wildlife Resources to initiate a study of moose demography in collaboration with Utah State University. The objectives of this study were to 1) determine reproductive rates of moose in Utah and the factors which influence them, and 2) combine aerial count data from multiple management units within the state to identify factors which influence interannual variation in population growth rates. We constructed generalized linear models to relate maternal body condition and age to reproductive success. We found that body condition (P = 0.01) and age (P = 0.02) contributed significantly to the probability of pregnancy and the best model describing this relationship was nonlinear. Body condition also related positively to subsequent calving (P = 0.08) and recruitment (P = 0.05), but model selection suggested the relationship for these metrics was best described by linear models. A meta-analysis of moose reproductive rates in North America suggested that reproductive rates declined significantly with latitude (P 9́Þ 0.01), i.e. as populations approached their southern range limit. We used Bayesian state-space models to combine moose count data from different management units to estimate statewide population dynamics between 1958 and 2013. This approach incorporated uncertainty in population counts arising from observation error. Population density and warm winter temperatures negatively influenced population growth rate with a high degree of confidence; 95% Bayesian Credible Intervals for these variables did not overlap zero. Short-term projections of moose abundance in the state suggested that the population will likely remain stable despite projected increases in winter temperature. Results from this study will aid managers in achieving management objectives as well as future decision making. The unique characteristics of the population also have application toward understanding the dynamics of populations of cold-adapted species at their southern range limit.

Download or read book Habitat Selection Condition and Survival of Shiras Moose in Northwest Wyoming written by Scott A. Becker and published by ProQuest. This book was released on 2008 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seasonal movements, habitat selection, physiological health, and demography of Shiras moose (Alces alces shirasi) were studied in the Jackson Valley of northwest Wyoming. Moose congregated on low-elevation ranges during winter and migrated to more dispersed, mid-elevation ranges during summer. Moose selected winter habitat dominated by deciduous shrubs, whereas they selected summer habitat that was more variable. Blood parameters indicated that moose were in moderate physical condition. Ultrasonic rump fat measurements were relatively high, but there were indications of nutritional deficiencies. Diseases and parasites appeared to have minimal population-level effects. Population modeling suggested that the moose population was more likely to be declining than stable or increasing and the population growth rate was influenced primarily by late-winter and early-spring adult female mortality. Pregnancy rates were high, but calf production was relatively low. Neonate and annual calf survival were relatively high. Habitat quality appeared to be the primary factor limiting population growth while the effects of predation appeared to be less important.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenic forces are dramatically altering the dynamics of many populations and ranges. A thorough understanding of drivers and mechanisms underlying population dynamics is needed to better understand reasons for range shifts and broaden our understanding of how environmental and demographic drivers affect population trajectories. In this thesis, I present two chapters that investigate the population dynamics of a rapidly colonizing moose (Alces alces) population in southwest Alaska. In the first chapter, I correlated environmental variables with demographic rates estimated using a multistate model and found that annual patterns of vegetation productivity and winter severity affected calf survival most strongly, followed by twinning rate. In the second chapter, I applied transient life table response experiments (tLTREs) to demographic rates and components of population structure estimated using an integrated population model (IPM). I found that, although calf survival did not have the highest sensitivity out of all other parameters, variation in calf survival contributed the most to variation in population growth rate. Together, these chapters suggest that variation in environmental conditions drove variation in population growth rate via effects on calf survival. Results uphold and add nuance to the demographic buffering hypothesis (DBH), which states that species evolve to buffer highest sensitivity demographic rates against variation that could otherwise decrease individual fitness and population sustainability. My research indicates that an outcome of the DBH is that lower sensitivity vital rates ultimately have a higher actual impact on population growth rate. Additionally, I found that the environmental drivers that currently limit population growth exhibit long-term trends consistent with climate change in ways that are amenable to moose, which suggests climate change facilitated moose colonization of the region. The lack of shortterm trends, lower adult survival in the most heavily hunted part of the study area, and the abrupt colonization that aligned with the irruption of a local caribou (Rangifer tarandus) herd indicate that human hunting pressure also played an important role in allowing moose to establish themselves at high density. These findings pertaining to drivers and mechanisms of population dynamics are relevant for conservation and management of large herbivores across the world that might similarly expand into new areas.

Download or read book Ecology written by Michael Begon and published by John Wiley & Sons. This book was released on 2020-11-17 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: A definitive guide to the depth and breadth of the ecological sciences, revised and updated The revised and updated fifth edition of Ecology: From Individuals to Ecosystems – now in full colour – offers students and practitioners a review of the ecological sciences. The previous editions of this book earned the authors the prestigious ‘Exceptional Life-time Achievement Award’ of the British Ecological Society – the aim for the fifth edition is not only to maintain standards but indeed to enhance its coverage of Ecology. In the first edition, 34 years ago, it seemed acceptable for ecologists to hold a comfortable, objective, not to say aloof position, from which the ecological communities around us were simply material for which we sought a scientific understanding. Now, we must accept the immediacy of the many environmental problems that threaten us and the responsibility of ecologists to play their full part in addressing these problems. This fifth edition addresses this challenge, with several chapters devoted entirely to applied topics, and examples of how ecological principles have been applied to problems facing us highlighted throughout the remaining nineteen chapters. Nonetheless, the authors remain wedded to the belief that environmental action can only ever be as sound as the ecological principles on which it is based. Hence, while trying harder than ever to help improve preparedness for addressing the environmental problems of the years ahead, the book remains, in its essence, an exposition of the science of ecology. This new edition incorporates the results from more than a thousand recent studies into a fully up-to-date text. Written for students of ecology, researchers and practitioners, the fifth edition of Ecology: From Individuals to Ecosystems is anessential reference to all aspects of ecology and addresses environmental problems of the future.
