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.

Rapidly changing glaciers in Alaska demonstrate tight physical and ecological linkages with downstream ecosystems that bridge the icefield-to-ocean continuum.

America has questions about climate change, and the USGS has real answers. In this episode of Climate Connections, USGS scientists answer questions gathered from downtown Denver, Colorado. Questions include:

This short Quicktime movie shows spattering from a cone near the south rim of Pu‘u ‘Ō‘ō crater as a short lava flow is erupted.

The effects of climate change on freshwater fishes and their habitats will likely not be consistent among species or habitats so region or species-specific effects of climate change may help managers focus conservation efforts.

This presentation, “Breaking Traditional Barriers to Model Climate Change and Land Use Impacts on Freshwater Mussels”, is a part of the Climate Change Science and Management Webinar Series from the USGS National Climate Change and Wildlife Science Center and the FWS National Conservation Training Center.

The Shoreline Management Tool is a GIS-based application used to assess how changes in water depth can affect an area. This includes identifying areas that may flood when water reaches a certain level or estimating how much water is available at any given time.

"Lake Mead — Clear and Vital" is a thirteen minute documentary relating the crucial role of science in maintaining high water quality in Lake Mead. The program was produced coincident with release of the Lakes Mead and Mohave Circular a USGS publication covering past and on-going research in the lakes and tributaries of the Lake Mead National Recreation Area.

This webinar gives an overview of the preliminary results from the project "La Florida: A Land of Flowers on a Latitude of Deserts". This webinar is a part of the "Climate Change and Management Webinar series" that is a partnership between the USGS National Climate Change and Wildlife Science Center and the FWS National Conservation Training Center.
