Mission Areas
Ecosystems
The USGS Ecosystems Mission Area, the biological research arm of the Department of the Interior (DOI), provides science to help America achieve sustainable management and conservation of its biological resources. This work is done within the broader mission of the USGS to serve the Nation with science that advances understanding of our natural resources and inform land and water stewardship.

Habitat features predict carrying capacity of a recovering marine carnivore
The recovery of large carnivore species from over‐exploitation can have socioecological effects; thus, reliable estimates of potential abundance and distribution represent a valuable tool for developing management objectives and recovery criteria. For sea otters (Enhydra lutris), as with many apex predators, equilibrium abundance is not constant...
Tinker, M. Tim; Yee, Julie L.; Laidre, Kristin L.; Hatfield, Brian; Harris, Michael D.; Tomoleoni, Joseph; Bell, Tom W.; Saarman, Emily; Carswell, Lilian P; Miles, A. Keith Seed production patterns of surviving Sierra Nevada conifers show minimal change following drought
Reproduction is a key component of ecological resilience in forest ecosystems, so understanding how seed production is influenced by extreme drought is key to understanding forest recovery trajectories. If trees respond to mortality-inducing drought by preferentially allocating resources for reproduction, the recovery of the stand to pre-drought...
Wright, Micah Charles; van Mantgem, Phillip J.; Stephenson, Nathan L.; Das, Adrian; Keeley, Jon Re-examination of population structure in Arctic ringed seals using DArTseq genotyping
Although Arctic ringed seals Phoca hispida hispida are currently abundant and broadly distributed, their numbers are projected to decline substantially by the year 2100 due to climate warming. While understanding population structure could provide insight into the impact of environmental changes on this subspecies, detecting...
