A variety of community and external pressures on Indigenous Peoples are leading to increased use of food that is available through industrialization and market economies; food in traditional food systems derived from local, natural environments is declining in use. This report focusses on dietary intake of Arctic men. While nutrient density of Arctic traditional food systems is superior to that of the composite of market food consumed in the North, the percentage of men's daily energy derived from market food is more than double that from traditional food in some communities. Older members of communities consume more traditional food than younger members; men consume more traditional food than do women. In addition...
Forests are important in the global carbon cycle, forming a major sink for carbon. Deforestation is a significant source of carbon dioxide emitted to the atmosphere. There is some scope to enhance natural carbon sinks, and therefore reduce net emissions of greenhouse gases, through afforestation and conservation of existing forests. Such initiatives may be implemented to "offset" emissions of greenhouse gases from other sources. This may be undertaken by private companies, or by governments as part of bilateral agreements or multilateral arrangements. International carbon offsets may be cost effective in terms of reduction of carbon emissions achieved, and may also be one way to mobilise private capital to fund...
The Loyalton mule deer (Odocoileus hemionus) herd winters west and northwest of Reno, Nevada along the California-Nevada border, extending into the Peterson Mountains, east of Highway 395 in Nevada. A portion of the herd also winters north of I-80 on Peavine Mountain in Nevada. This population represents an interstate migratory herd but also contains year-round residents in both states. Deer migrate southwest into the Sierra Nevada Mountains of California on both sides of Highway 89 from Truckee to Sierraville, mostly staying north of I-80 and into the Tahoe National Forest. Significant challenges include urban development, vehicle collisions on Highways 89, 395, and I80, and large-scale wildfires that have burned...
Mule deer (Odocoileus hemionus) of the Kaibab Plateau in Arizona had a population estimate of 10,200 individuals in 2019. The herd is relatively isolated; limited in range to the east, south, and west sides by the Grand Canyon. Annually the Kaibab herd migrates an average of 27 mi (43 km) between summer and winter range. Winter range is along the west, east, and northern extents of the plateau; consisting of pinyon-juniper woodlands mixed with sagebrush, cliffrose, bitterbrush, and various grasses. Some of the Kaibab herd winters in Utah, sharing winter range with Utah’s Paunsaugunt Plateau herd. During migration mule deer pass through mid-elevation transitional range containing Gambel oak, pinyon pine, and Utah...
The San Francisco Peaks mule deer (Odocoileus hemionus) herd makes one of Arizona’s most extraordinary annual migrations between Flagstaff, AZ and the Grand Canyon. The migration begins on summer range in GMU 7, where an estimated 5,300 mule deer reside. Their summer habitat contains alpine, subalpine, and ponderosa pine forests mixed with open grasslands and meadows. Beginning in October, a portion of the herd migrates north to GMU 9 to winter range along the South Rim containing pinyon-juniper, ponderosa pines, sagebrush, and cliffrose habitat. Through funding from Secretarial Order 3362, the Arizona Game and Fish Department (AZGFD) began a GPS collar study beginning in June of 2019. A total of 46 mule deer have...
The mule deer (Odocoileus hemionus) of the Pueblo of Santa Ana herds are primarily non-migratory, with two distinct winter ranges separated by U.S. Route 550. The winter ranges consist primarily of Chihuahuan semi‚Äźdesert grassland, dominated by black grama (Bouteloua eriopoda), galleta (Pleuraphis jamesii), mesa dropseed (Sporobolus flexuosus), and fourwing saltbush (Atriplex canescens), with higher elevation sections consisting of pinyon-juniper woodland and juniper savannah. There was no movement between the two winter ranges, with only individuals from the winter range northeast of US 550 crossing the highway west of the Jemez Canyon Reservoir. Two individuals from the winter range northeast of US 550 migrated...
The South of Interstate 40 (I-40) pronghorn (Antilocapra americana) herd make one of Arizona’s most remarkable migrations. This herd resides primarily in GMU 8, which had a population estimate of 450 individuals in 2019. Unlike traditional summer-winter range dynamics, this pronghorn herd relies on a complex of several important seasonal ranges connected by narrow corridors. Migration between ranges appear to be driven by winter conditions, thus, the timing of the movements is highly variable. The herd has high fidelity to these corridors, which elevates the importance of research and management efforts to conserve them. During the summer, these pronghorn inhabit large grasslands in and around Garland Prairie. During...

As the SEAK Hydro database evolves, so to will the metadata for this dataset. Until noted otherwise, please reference this dataset's metadata for an older version of the source data.This map service contains two barrier layers, one from the USFS and one from the AWC. The USFS barriers layer contains points representing bedrock waterfalls in Southeast Alaska that are potential barriers to fish passage on the Tongass National Forest. Waterfalls less than 1 meter are not mapped nor are those caused only by wood or debris jams. Channel types considered to be de facto barriers to fish passage HC5, HC6, & MC3 (Channel Type Users Guide, USFS 1992) were not included in the layer. The AWC layer is undocumented at this time.

In this observational pilot study, we worked at the largest existing solar tower facility in the world (Ivanpah Solar Electric Generating System - ISEGS) to assess the efficacy of using radar, surveillance video, and insect trapping to monitor animals flying near the towers. During week-long site visits in May and September, we monitored the airspace surrounding towers and observed insects, occasional birds, and bats under a variety of environmental and operational conditions. This dataset enumerates invertebrates captured using both malaise and funnel traps placed on the ground in the immediate vicinity of solar towers in the locations shown in Figure 2 of the associated paper. The locational information below...

Important Bird Areas (IBAs), are sites that provide essential habitat to one or more species of birds during some portion of the year (nesting areas, crucial migration stop-over sites, or wintering grounds). IBAs may be a few or even thousands of acres, but usually are discrete sites that stand out from the surrounding landscape. IBAs may include public or private lands, or both, and they may be already protected or not. IBA Protection Although the IBA program has no regulatory authority, it protects birds by making more people aware of the importance of essential habitat areas, and by promoting public and private commitment to bird-friendly land and resource management.

These bat location estimates have been reported by Bogan and others (In press) and come in the form of a GIS shape file. Three species of nectar-feeding phyllostomid bats migrate north from Mexico into deserts of the United States (U.S.) each spring and summer to feed on blooms of columnar cacti and century plants (Agave spp). However, the habitat needs of these important desert pollinators are poorly understood. We followed the nighttime movements of two species of long-nosed bats (Leptonycteris yerbabuenae and L. nivalis) in an area of late-summer sympatry at the northern edges of their migratory ranges. We radiotracked bats in extreme southwestern New Mexico during 22 nights over two summers and acquired location...
The Paunsaugunt Plateau in southern Utah is home to a prolific mule deer herd numbering around 5,200 individuals in 2019. In early October, these mule deer begin their migration from the Plateau traveling south distances up to 78 miles to winter range in the Buckskin Mountains near the Utah-Arizona border. Approximately 20-30% of the Paunsaugunt Plateau herd reside in northern Arizona during the winter, sharing winter range also used by deer from the Kaibab Plateau herd. Beginning in late April, deer reverse their migration to summer range on the Plateau. The most significant challenge for these deer is US Highway 89 which bisects this migration corridor and winter range, where deer-vehicle collisions have historically...
