Creator:: Moriarty, Katie M., Epps, Clinton W., Betts, Matthew G., Hance, Dalton J., Bailey, J. D., and Zielinski, William J.
Abstract:: Context: Functional connectivity—the facilitation of individual movements among habitat patches—is essential for species’ persistence in fragmented landscapes. Evaluating functional connectivity is critical for predicting range shifts, developing conservation plans, and anticipating effects of disturbance, especially for species affected by climate change. Objectives: We examined whether simplifying forest structure influenced animal...

Abstract:: Predicting biodiversity responses to climate change remains a difficult challenge, especially in climatically complex regions where precipitation is a limiting factor. Though statistical climatic envelope models are frequently used to project future scenarios for species distributions under climate change, these models are rarely tested using empirical data. We used long-term...

Creator:: Bennett, Victoria J., Pack, Shalynn M., Smith, Winston P., and Betts, Matthew G.
Abstract:: The survival of many species may be dependent on their ability to exist in human-altered landscapes within metapopulations; in turn, metapopulation persistence is dictated by the ability of individuals to move effectively among patches to promote recolonization. The Taylor’s checkerspot butterfly (Euphydryas editha taylori) is a species that does not...

Creator:: Jenkins, Stephanie R., Betts, Matthew G., Huso, Manuela M., and Hagar, Joan C.
Abstract:: Lower order, non-fish-bearing streams, often termed ‘‘headwater streams’’, have received minimal research effort and protection priority, especially in mesic forests where distinction between riparian and upland vegetation can be subtle. Though it is generally thought that breeding bird abundance is higher in riparian zones, little is known about species distributions...

Creator:: Jones, Jay E., Kroll, Andrew J., Giovanini, Jack, Duke, Steven D., Ellis, Tana M., and Betts, Matthew G.
Abstract:: •Background: Managers of landscapes dedicated to forest commodity production require information about how practices influence biological diversity. Individual species and communities may be threatened if management practices truncate or simplify forest age classes that are essential for reproduction and survival. For instance, the degradation and loss of complex diverse forest...

Creator:: Swatantran, Anu, Dubayah, Ralph, Goetz, Scott, Hofton, Michelle, Betts, Matthew G., Sun, Mindy, Simard, Marc, and Holmes, Richard
Abstract:: Background: Improved maps of species distributions are important for effective management of wildlife under increasing anthropogenic pressures. Recent advances in lidar and radar remote sensing have shown considerable potential for mapping forest structure and habitat characteristics across landscapes. However, their relative efficacies and integrated use in habitat mapping remain largely...
