Recent declines in nesting success of some fish-eating seabirds in Alaska have been attributed to declines in availability of certain schooling forage fishes (e.g., capelin Mallotus villosus, Pacific sand lance Ammodytes hexapterus, and Pacific herring Clupea harengus pallasi). These fishes tend to have high lipid content compared with other species...
Past tracking studies of marine animals have primarily targeted adults, biasing our understanding of at-sea habitat use toward older life stages. Anthropogenic threats persist throughout the at-sea ranges of all life stages and it is therefore of interest to population ecologists and managers alike to understand spatiotemporal distributions and possible...
Offering courses that promote, encourage, and support physical activity among college students has been an aim of physical education departments for the past century (Sargeant, 1900). Even so, this population has been identified in Healthy People 2010 as a target population segment in need of physical activity intervention. Historically, such...
We compared the abundance, diversity, and composition of truffles in riparian and upland areas within a
mixed-conifer forest of the Sierra Nevada of California. We sampled for truffles in a single watershed over two seasons
(spring and summer) and 4 years to determine whether truffles were more abundant and diverse...
In this paper we report on the available X-ray data collected by INTEGRAL, Swift, and XMM-Newton during the first outburst of the INTEGRAL transient IGR J17451–3022, discovered in 2014 August. The monitoring observations provided by the JEM-X instruments on board INTEGRAL and the Swift /XRT showed that the event lasted for about...
In many western North American forests, prescribed burning and mechanical thinning are widely used to reduce
fuels and restore stand conditions after a century of fire suppression. Few studies have followed the relative impacts
of these treatments on the production and consumption of truffles in forest ecosystems, particularly in the...
We examined the nest-tree preferences of northern flying squirrels (Glaucomys sabrinus) in an old-growth,
mixed-conifer and red fir (Abies magnifica) forest of the southern Sierra Nevada of California. We tracked 27
individuals to 122 nest trees during 3 summers. Flying squirrels selected nest trees that were larger in diameter
and...
Prescribed burning and mechanical thinning are used to manage fuels within many western North American forest ecosystems, but few studies have examined the relative impacts of these treatments on forest wildlife. We sampled northern flying squirrels (Glaucomys sabrinus) and microhabitat variables in burned, thinned and control stands of mixed-conifer forest...
The diets of a fungal specialist, northern flying squirrel (Glaucomys sabrinus (Shaw, 1801)), and a dietary generalist,
lodgepole chipmunk (Neotamias speciosus (Merriam, 1890)), were examined in the old-growth, mixed-conifer forest
at the Teakettle Experimental Forest in California’s southern Sierra Nevada. Spores of fungi were identified from fecal
pellets collected from...
