Home
We provide rigorous and unbiased information on migratory birds, terrestrial and marine mammals, amphibians and reptiles, terrestrial plants, threatened and endangered species, wildlife disease, and on wildlife issues resulting from human activities. Our science contributes toward a more complete understanding of the Nation’s ecosystems and landscapes.
An ARMI of Many
The USGS Amphibian Research and Monitoring Initiative (ARMI) provides critical information about amphibian populations and life history traits, environmental characteristics, and potential causes of decline.

Effects of experimental removal of Barred Owls on population Demography of Northern Spotted Owls in Washington and Oregon—2018 Progress Report
Populations of Northern Spotted Owls (Strix occidentalis caurina; herineafter referred to as Spotted Owl) have declined throughout the subspecies’ geographic range. Evidence indicates that competition with invading Barred Owls (S. varia) has contributed significantly to those declines. A pilot study in California showed that removal of Barred Owls...

Nonlinearities in transmission dynamics and efficient management of vector-borne pathogens
Integrated Pest Management (IPM) is an approach to minimizing economic and environmental harm caused by pests, and Integrated Vector Management (IVM) uses similar methods to minimize pathogen transmission by vectors. The risk of acquiring a vector-borne infection is often quantified using the density of infected vectors. The relationship between...
Ginsberg, Howard S.; Couret, Jannelle Genetic tagging in the Anthropocene: Scaling ecology from alleles to ecosystems
The Anthropocene is an era of marked human impact on the world. Quantifying these impacts 51 has become central to understanding the dynamics of coupled human-natural systems, resource52 dependent livelihoods, and biodiversity conservation. Ecologists are facing growing pressure to 53 quantify the size, distribution, and trajectory of wild...
