Invader Removal Halts Long-term Population Declines of Northern Spotted Owls

Invasive species can cause extinctions of native species and widespread biodiversity loss. Invader removal is a common management response, but the use of long-term field experiments to test the effectiveness of removals in benefitting impacted native species is rare.

Species Interactions Shape Increasing Rates of Breeding Dispersal of Northern Spotted Owls

Recent evidence suggests that frequency of breeding dispersal – the movement from one breeding territory to another – may be increasing in northern spotted owl populations, which could have consequences on population dynamics of this declining species.

Predicted Climate-Induced Reductions in Scavenging in Eastern North America

Scavenging is an important function within ecosystems. Scavengers remove organic matter, reduce disease, stabilize food webs, and generally make ecosystems more resilient to environmental changes.

Isotope Fractionation from In Vivo Methylmercury Detoxification in Waterbirds

Animals that are higher on the trophic chain, such as waterbirds that primarily rely on fish, are at risk for ingesting methylmercury in their diet, which is then stored in their tissues and cycles through their organs.

Insect Pollinator Communities in Sagebrush Steppe Ecosystems

The conservation of native insect pollinators is hampered by a lack of information about environmental factors influencing pollinator communities.
