Book excerpt: "Muskox (Ovibos moschatus) are a large-bodied arctic herbivore that occupy habitats used seasonally by migratory caribou (Rangifer tarandus). Muskox were reintroduced to the North Slope of Alaska in 1970 and mixed-sex groups have been reported in the Yukon North Slope and the Richardson Mountains since 1985. Their reintroduction has sparked concerns from local hunters and community members worried about the impact of muskox on caribou populations and vegetation. This thesis represents an ecological assessment of competition potential and habitat segregation among two arctic ungulates and community-based research that addresses local concerns and knowledge priorities. In the first part of the thesis, I use satellite collar data from muskox and caribou to analyze their spatial and habitat overlap through range overlap, encounter rates, and resource selection functions. Range overlap was at its highest in the spring and summer months, but less than 1% of collared caribou encountered a muskox during that period. Habitat overlap was minimized through differential selection of elevation, distance to water, and abundant tussock habitat. In the second part of the thesis, I use ground-based vegetationsampling to characterize fine-scale muskox-vegetation associations, determining whether there arepositive or negative associations between muskox use and vegetation presence and abundance. Positive associations between muskox use and vegetation attributes were deemed to reflect a pattern of fine-scale selection, and negative associations were deemed to be the reflection of muskox herbivory impacts. Positive associations were found between muskox use and lichen, willow, and graminoid abundance and presence, an indication that within land covers, the relationship between muskox use and vegetation is mostly driven by selection rather than by herbivory. Collectively, this research reveals that in the Yukon North Slope and Richardson Mountains, the reintroduced and expanding population of muskox i) has low encounter rates and differential habitat use with caribou and ii) has selection patterns that are quantifiable at a large and at a fine-scale"--

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An aerial caribou and muskox strip transect survey was conducted on northwest Victoria Island between May 8th and May 24th, 2019. Two Cessna 206 fixed-wing aircraft were used for the survey. The survey area was divided into four strata or blocks, named A, B, C and E. Strata A, B and C had been used in previous surveys of this area. There were 30 adult caribou observed on transect and 14 adult caribou observed off transect. The majority of caribou were observed in survey stratum C except for one group of 14 caribou observed in survey stratum A. The population estimate for adult caribou in survey stratum A was 78±136 (95% Confidence Interval (CI)). The population estimate for adult caribou in survey stratum C was 98±91 (95% CI). These estimates have a high variance so should be used with caution, and overall caribou numbers remain low. There were 962 adult and 100 calf muskoxen observed on transect and 1,482 muskoxen observed off transect lines. The population estimate for survey strata A, B and C combined was 5,550±1,672 (95% CI) adult muskox. This is lower than the 2015 estimate for these strata and indicates an annual decline of 16%. The population estimate for survey stratum E was 216±206 (95% CI) adult muskox.

Available in PDF, EPUB and Kindle. Book excerpt: "What caused the extinction of so many animals at or near the end of the Pleistocene? Was it overkill by human hunters, the result of a major climatic change or was it just a part of some massive evolutionary turnover? Questions such as these have plagued scientists for over one hundred years and are still being heatedly debated today. Quaternary Extinctions presents the latest and most comprehensive examination of these questions." —Geological Magazine "May be regarded as a kind of standard encyclopedia for Pleistocene vertebrate paleontology for years to come." —American Scientist "Should be read by paleobiologists, biologists, wildlife managers, ecologists, archeologists, and anyone concerned about the ongoing extinction of plants and animals." —Science "Uncommonly readable and varied for watchers of paleontology and the rise of humankind." —Scientific American "Represents a quantum leap in our knowledge of Pleistocene and Holocene palaeobiology. . . . Many volumes on our bookshelves are destined to gather dust rather than attention. But not this one." —Nature "Two strong impressions prevail when first looking into this epic compendium. One is the judicious balance of views that range over the whole continuum between monocausal, cultural, or environmental explanations. The second is that both the data base and theoretical sophistication of the protagonists in the debate have improved by a quantum leap since 1967." —American Anthropologist

Download or read book Availability of Caribou and Muskoxen for Local Human Consumption Across Nunavut written by Marie-Andrée Giroux and published by . This book was released on 2012 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report was prepared at the request of the Nunavut Anti-Poverty Secretariat (hereafter NAPS) to provide scientific advice related to the feasibility concerning the inclusion of caribou, reindeer, and muskoxen populations in its community-based harvesting program. The Wildlife Research Section, Nunavut Department of Environment, cannot provide a broad recommendation that the Nunavut Anti-Poverty Secretariat assist communities in purchasing barrenground caribou meat, reindeer meat or Peary caribou meat from harvesters due primarily to data gaps that currently exist in our understanding of the demographic status of many of these populations. For muskoxen, a few management units may be good candidates for implementation of a community-based harvesting program, yet resources to update and monitor these populations, in terms of status and harvest activities, would be necessary to ensure their sustainability. The details behind our recommendations are summarized below: BARRENGROUND CARIBOU (Rangifer tarandus groenlandicus): 1. Caribou is a highly valued food source for which harvest by Nunavut Land Claim Agreement (NLCA) beneficiaries is not restricted through legislation, unless a conservation issue requiring a Total Allowable Harvest (TAH) arises. 2. Reporting of caribou harvest is not mandatory in Nunavut outside of the application of a TAH. 3. Unsustainable harvesting is one of the potential causes of current or historical declines of some barrenground caribou herds in Nunavut. 4. An update of the status of most caribou herds across Nunavut would be required for the purpose of effectively managing caribou harvest. REINDEER (Rangifer tarandus tarandus): 1. There is a paucity of recent information on the single population of introduced reindeer found in Nunavut (Belcher Islands). 2. Some residents of Sanikiluaq have raised serious concerns about management of harvesting activities. 3. A ground survey was conducted in winter 2012 in order to update the status of this population. PEARY CARIBOU (Rangifer tarandus pearyi): 1. Caribou is a highly valued food source for which harvest by NLCA beneficiaries is not restricted through legislation, unless a conservation issue requiring TAH arises. 2. Reporting of caribou harvest is not mandatory in Nunavut outside of the application of a TAH. 3. Peary caribou was listed as endangered under the federal Species At Risk Act (SARA) in February 2011. 4. Harvesting of Peary caribou should be conducted according to recommendations that will be included in the federal recovery strategy and the territorial management plan, which are currently being developed. 5. Peary caribou are susceptible to abrupt changes in population size due to unpredictable severe weather events across their range. The frequency of these weather events is expected to increase with climate change. MUSKOX (Ovibos moschatus): 1. Muskox harvesting is restricted through legislation and TAHs have been established for management units across Nunavut. 2. Reporting of the harvest is mandatory through the use of tags. 3. An update of the status of most muskoxen populations or management units across Nunavut would be required for the purpose of effectively managing muskox harvest. 4. A few management units (MX07, MX10, MX11, MX15, and MX16) may be good candidates for a community-based harvesting program pending human and financial resources to update population's status and implement adequate monitoring linked to an eventual increase in harvest pressure. 5. Muskoxen in the high arctic are susceptible to abrupt changes in population size due to unpredictable severe weather events across their high arctic range. The frequency of these weather events is expected to increase with climate change. In conclusion, this report highlights the general lack of knowledge and/or up-to-date information about harvest levels and population status available to the Wildlife Research Section for the purposes of effectively managing the harvest of car ibou and reindeer. In some areas, this limitation could be overcome if reporting caribou harvest becomes mandatory, and if long-term monitoring programs of population demographic parameters are established"--ASTIS [online] database.
