Summary
Gray wolves (Canis lupus) have expanded their range significantly since reintroduction. A recent camera trap in Nevada marks a rare confirmed gray wolf sighting, suggesting potential for establishment in the Great Basin.
Area of Science:
- Wildlife biology
- Ecology
- Conservation science
Background:
- Gray wolves (Canis lupus) were reintroduced to Yellowstone National Park and central Idaho in the mid-1990s.
- The species' range has since expanded into several western US states, including California by 2011.
- Gray wolf presence in open, nonforested areas like the northern Great Basin has been sporadic.
Purpose of the Study:
- To document the presence of gray wolves in northwest Nevada.
- To assess the significance of this observation in the context of the species' historical range and potential for future establishment.
Main Methods:
- A broad-scale, camera-trapping study was conducted in northwest Nevada.
- An unbaited camera trap captured an image of a gray wolf.
Main Results:
- A gray wolf was detected via camera trap in northwest Nevada.
- This represents the second confirmed gray wolf sighting in Nevada since the 1920s.
- It is the first camera trap detection of a gray wolf in the state.
Conclusions:
- The confirmed gray wolf detection in Nevada is a significant event.
- This finding warrants further investigation into the potential for gray wolf establishment in the northern Great Basin ecosystem.

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
