In this video, a bobcat approached a desert tortoise (a marked female in the study population) that was sleeping on the apron of her burrow. Bobcats are known predators of various life stages of the desert tortoise. In this case, the bobcat bent down to sniff the tortoise, and then touched its paw to the top of the tortoise's shell.

This time lapse video, composed of daily still photographs, shows a dry year in the life of The Nature Conservancy's Silver Creek Preserve near Picabo, Idaho. Climate variability and other factors raise concerns about elevated stream temperatures that stress fish and other aquatic life.

This American black bear and cub duo was seen simply investigating a tortoise burrow, and although it is surprising to see a black bear so low in elevation, it isn't impossible. The study site, Mesa, sits at the intersection of multiple ecosystems (Sonoran Desert, Mojave Desert, montane, and coastal sage scrub).

Coyotes were the second most frequently observed mammalian predator on the trail cameras. Coyotes are considered one of the primary predators of desert tortoises. In this instance, a coyote is passing by a burrow when it suddenly has a change in attention as it is passing by.

This presentation, "A mammal's take on the Rapture Hypothesis, Jacob's Ladder, and other notions of doom, gloom, and predictable uniform change in high elevation ecosystems of the Sierra Nevada", was conducted by Robert Klinger as a part of the Climate Change Science and Management Webinar Series.

This clip shows a Hawaiian hoary bat (Lasiurus cinereus semotus)flying near a turbine as imaged with a thermal camera. The recording shows the bat investigating the area immediately around the turbine nacelle. This activity is of particular interest to researchers because it provides a window into behavior that places bats at risk from turbine strikes.

Brian Pellerin, member of the Powell Center Dissolved Organic Matter Transported by Rivers Working Group, discusses the Working Group's activities in a seminar at the Fort Collins Science Center. The original seminar was approximately 55 minutes in length. This video provides a five and a half minute synopsis of the presentation.

The effects of climate change on fish habitat will be scale-and system-dependent. Our work demonstrates how climate change affects fish habitat nationwide, and stream flow, water temperature, and coldwater lakes in the Upper Midwest. Projected changes in fish habitat varied across ecoregions nationally.
