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...
Observers at Hakalau Forest National Wildlife Refuge recorded the use by birds of koa (Acacia koa) and ohia (Metrosideros polymorpha) trees in two sites that were recovering from ungulate disturbance and two reforestation sites where trees had been planted. Observations were made pre- and post-defoliation of koa trees by koa moths (Scotorythra paludicola) during 2013. Focal trees at each site were selected haphazardly and observed for 2 minutes to determine the total number individual birds that visited the tree. Birds were counted when they were already present or as they flew into a tree during the 2-minute period, regardless of whether they departed before the end of the observation period. Birds were identified...

This dataset includes 2020 reach fish data and reach habitat data collected to support development of the upper Santa Ana River Habitat Conservation Plan for the Santa Ana Sucker (Catostomus santaanae) and the Arroyo Chub (Gila orcutti) in the Santa Ana River, California.
Little information is available on the use of areas enrolled in the Conservation Reserve Program (CRP) by Gunnison sage-grouse (Centrocercus minimus) or the impacts of grazing on their habitat selection and movement patterns. Using radiotelemetry, we monitored 13 Gunnison sage-grouse in San Juan County, Utah, USA during 20012002 to determine their use of CRP. Additionally, in 2002 some of the CRP land used by the birds in 2001 was grazed under a drought emergency declaration. This afforded us an opportunity to monitor their response to livestock grazing. Although Gunnison sage-grouse used CRP for nesting, brood-rearing, and summer habitat, it was not selected in greater proportion than its availability (P 0.10)...

Trout Unlimited will extend its existing Adopt-a-Trout program to the Henrys Fork River, a tributary to the Green River in the Colorado River basin. The project will include work with the Wyoming Game and Fish Department and local schools to tag and monitor Colorado River Cutthroat trout movements to learn more about fish passage issues, areas of high entrainment, habitat use, and native and wild trout migratory patterns. Colorado River Cutthroat trout are native to the Henrys Fork River and occupy portions of the drainage; however, no data exists for Colorado River Cutthroat trout in the Wyoming portion of the Henrys Fork drainage to understand population dynamics and habitat restraints.FY2014Trout Unlimited will...

This study investigated local distribution and foraging behavior of the spotted bat (Euderma maculatum) in Dinosaur National Monument, Colorado-Utah, by monitoring audible echolocation calls. The occurrence of this species was verified in a variety of habitat types in canyon bottoms and other relatively low elevation sites, indicating that the animals were widely distributed and locally common in the area. Foraging spotted bats concentrated flight activity in the open-air space above meadows occasionally exploited near-canopy habitat (within 8 m of foliage). Bats began to forage shortly after dark, and activity levels were relatively constant throughout the night. Foraging spotted bats attacked airborne prey every...

This datasets summarizes small mammal trapping efforts that USGS San Francisco Bay Estuary Field Station has led, co-led, or supervised, to detect and monitor the endangered salt marsh harvest mouse (Reithrodontomys raviventris) in the northern reaches of San Francisco Bay from 1998-2014. As the salt marsh harvest mouse is listed as endangered under the Endangered Species Act, sensitive location information can be made available upon request by contacting the dataset point of contact. These data support the following publication: Marcot, B.G., Woo, I., Thorne, K.M., Freeman, C.M., and Guntenspergen, G.R., 2020.

Habitat use and relative abundance of the spotted bat, Euderma maculatum, were examined in the river canyons of Dinosaur National Monument, Colorado, by monitoring audible echolocation calls. Spotted bats were found at all canyon sites, but were less common than other species of bats. We found no indications of foraging habitat restrictions. Spotted bats foraged ca. 10 m high and were active from dusk into the early morning hours. Published in Journal of Mammalogy, volume 73, issue 3, on pages 547 - 551, in 1992.

We determined temporal and spatial differences in abundance and habitat use by small mammals in southeastern Utah as part of an effort to enhance management of the Mexican Spotted Owl (Strix occidentalis lucida), listed by the federal government as threatened. Woodrats (Neotoma spp.) were captured only in canyons and most frequently in the pinyon-juniper (Pinus edulis-Juniperus osteosperma) vegetation type. White-footed mice (Peromyscus spp.) were found in a variety of vegetation types in both canyons and mesas. The deer mouse (P. maniculatus) was generally the most frequently captured species among vegetation types. We found seasonal and yearly differences in relative abundance of each small mammal species. Our...

1. Wind power plants represent a risk of bird mortality, but the effects are still poorly quantified. We measured bird mortality, analysed the factors that led birds to fly close to turbines, and proposed mitigation measures at two wind farms installed in the Straits of Gibraltar, one of the most important migration bottlenecks between Europe and Africa. 2. Bird corpses were surveyed along turbine lines and an associated power line to estimate mortality rates. The behaviour of birds observed within 250 m of turbines was also recorded as a putative indicator of risk. The effects of location, weather and flight behaviour on risk situations (passes within 5 m of turbines) were analysed using generalized linear modelling...
