A Report On Black-Tailed Prairie Dogs In Nebraska-- Their Biology, Behavior, Ecology, Management, And Responses To A Visual Barrier Fence
Dissertations & Theses in Natural Resources
I examined the effects of a visual barrier fence, which had a see-through visibility of 600/0, on the foraging, vigilance, and aggressive behaviors of adult female black-tailed prairie dogs from June through August 1990 in central Nebraska. I also examined changes in their home ranges and use of an area in response to this fence. Prairie dogs prefer an open view of their surroundings. Therefore, I expected animals near a visual barrier to spend more time in vigilance and aggression, and less time foraging. Adult female prairie dogs exposed to the visual barrier devoted more time to foraging and less …

This report serves as a 2024 snapshot of key issues and concerns with Utah’s shared resources. It highlights a collection of data that is available to provide context to these issues and identifies areas where more study is needed. Addressing these challenges will enable Utah policymakers to make informed decisions for the future. Under the authorship of 52 researchers and with the support of 47 advisory board members, this report includes 6 chapters (Land, Water, Air, Forests and Rangelands, Bear Lake, and Metrics) that address the focus areas of the report.
Achievement Of Wetland Protection And Restoration And Development Strategies In China,

Achievement Of Wetland Protection And Restoration And Development Strategies In China, Hui Zhu, Ming Jiang, Haitao Wu
Bulletin of Chinese Academy of Sciences (Chinese Version)
Wetland provides various ecological functions, and wetland protection and restoration directly affect national security, sustainability of economy and society, as well as human well-being. This study has systematically summarized the current status of wetland resource and the achievement of wetland protection in China, and the conclusions will provide scientific support for the policy making in wetland protection and management. The area of wetland in China was 41.2×104 km2 based on remote sensing monitoring in 2020, which lead the first in Asia. Since the 18th National Congress of the Communist Party of China (CPC), the area of wetland has showed a …
A Review Of Vegetation Phenological Metrics Extraction Using Time-Series, Multispectral Satellite Data,
University of Nebraska - Lincoln
A Review Of Vegetation Phenological Metrics Extraction Using Time-Series, Multispectral Satellite Data, Brian Wardlow
School of Natural Resources: Faculty Publications
Vegetation dynamics and phenology play an important role in inter-annual vegetation changes in terrestrial ecosystems and are key indicators of climate-vegetation interactions, land use/land cover changes, and variation in year-to-year vegetation productivity. Satellite remote sensing data have been widely used for vegetation phenology monitoring over large geographic domains using various types of observations and methods over the past several decades. The goal of this paper is to present a detailed review of existing methods for phenology detection and emerging new techniques based on the analysis of time-series, multispectral remote sensing imagery. This paper summarizes the objective and applications of detecting …
Movement Of Smallmouth Bass Within The Beaver Island Archipelago, Northern Lake Michigan.,

Movement Of Smallmouth Bass Within The Beaver Island Archipelago, Northern Lake Michigan., Mark Kaemingk
Papers in Natural Resources
Fish movement may vary across a wide array of aquatic ecosystems and may be related to the overall size of the system inhabited. We investigated movement of smallmouth bass in Lake Michigan because this information is lacking for larger systems. A total of 16 smallmouth bass were surgically implanted with ultrasonic transmitters within the Beaver Archipelago, northern Lake Michigan. During 2007–2008, a maximum of one location per individual was recorded daily during three specific tracking periods – pre-spawn, spawning, and post-spawn – to determine diurnal movement patterns. Movement was evaluated as site fidelity, minimum displacement rate,maximumexcursion rate, and distance from …
Pathology Of Chronic Mycoplasma Ovipneumoniae Carriers In A Declining Bighorn Sheep (Ovis Canadensis) Population,

Pathology Of Chronic Mycoplasma Ovipneumoniae Carriers In A Declining Bighorn Sheep (Ovis Canadensis) Population, Jennifer Malmberg
United States Department of Agriculture Wildlife Services: Staff Publications
Bighorn sheep (Ovis canadensis) across North America commonly experience populationlimiting epizootics of respiratory disease. Although many cases of bighorn sheep pneumonia are polymicrobial, Mycoplasma ovipneumoniae is most frequently associated with all-age mortality events followed by years of low recruitment. Chronic carriage of M. ovipneumoniae by adult females serves as a source of exposure of naïve juveniles; relatively few ewes may be responsible for maintenance of infection within a herd. Test-and-remove strategies focused on removal of adult females with evidence of persistent or intermittent shedding (hereafter chronic carriers) may reduce prevalence and mitigate mortality. Postmortem confirmation of pneumonia …
The Green, Blue And Grey Water Footprint Of Farm Animals And Animal Products. Volume 1: Main Report,

The Green, Blue And Grey Water Footprint Of Farm Animals And Animal Products. Volume 1: Main Report, Mesfin Mekonnen, Arjen Hoekstra
Daugherty Water for Food Global Institute: Faculty Publications
The projected increase in the production and consumption of animal products is likely to put further pressure on the globe’s freshwater resources. The size and characteristics of the water footprint vary across animal types and production systems. The current study provides a comprehensive account of the global green, blue and grey water footprints of different sorts of farm animals and animal products, distinguishing between different production systems and considering the conditions in all countries of the world separately. The following animal categories were considered: beef cattle, dairy cattle, pig, sheep, goat, broiler chicken, layer chicken and horses. The study shows …
Burmese Pythons In Florida: A Synthesis Of Biology, Impacts, And Management Tools,

Burmese Pythons In Florida: A Synthesis Of Biology, Impacts, And Management Tools, Jacquelyn Guzy
USDA Wildlife Services - Staff Publications
Burmese pythons (Python molurus bivittatus) are native to southeastern Asia, however, there is an established invasive population inhabiting much of southern Florida throughout the Greater Everglades Ecosystem. Pythons have severely impacted native species and ecosystems in Florida and represent one of the most intractable invasive-species management issues across the globe. The difficulty stems from a unique combination of inaccessible habitat and the cryptic and resilient nature of pythons that thrive in the subtropical environment of southern Florida, rendering them extremely challenging to detect. Here we provide a comprehensive review and synthesis of the science relevant to managing invasive …
Notes: Range Extension Of The Virginia Opossum (Didelphis Virginiana) In North Dakota,
University of Nebraska - Lincoln
Notes: Range Extension Of The Virginia Opossum (Didelphis Virginiana) In North Dakota, Lisa Walsh
The Prairie Naturalist
The Virginia opossum (Didelphis virginiana) is broadly distributed across North America from Costa Rica in the south to southern Ontario in the north and from the southern Great Plains in the west to the eastern United States. The Virginia opossum also was introduced multiple times to thePacific Coast beginning in the late 1800s and has established populations in that region (Gardner and Sunquist 2003). This species is a habitat generalist known to frequent wetland and hardwood habitats but also can be found in grasslands, along forest edges, and in agricultural and suburban settings throughout its range (Gardner and Sunquist 2003, …
The Other Side Of Silence: Rachel Carson’S Views Of Animals,

The Other Side Of Silence: Rachel Carson’S Views Of Animals, Marc Bekoff
Animal Abuse, Animal Welfare, and Animal Protection
The publication of Rachel Carson’s Silent Spring in 1962 is widely regarded as one of the major events that launched the modern environmental movement. Silent Spring is a compelling blend of stories, natural history, human values, and biological facts. In this essay we consider Carson’s attitude toward animals in Silent Spring and in other texts. Despite the facts that she was raised to love Nature and animals, little direct attention has been given to Carson’s views about our moral responsibilities to, and the moral standing of animals. Carson favored responsible stewardship, was more of an animal welfarist and environmentalist/conservation biologist …
