Researchers tracked the movements of endangered caribou and sequenced a portion of their genomes to determine which genes may influence migratory behavior.
Splitting Chinook salmon into two groups based on their DNA could aid conservation efforts. But some researchers argue that this would be a misuse of the data.
In the 20th century, animals such as mules and ligers that had parents of different species were considered biological flukes, but genetic sequencing is beginning to unravel the critical role of hybridization in evolution.
From fish harvests to cottonwood forests, organisms display evidence that species change can occur on timescales that can influence ecological processes.
Researchers find that conserving marsupials on a predator-free island dampens their avoidance behaviors, which could mean trouble for their reintroduction to mainland Australia.
The genomes of living animals are littered with DNA from long-gone relatives, providing a lens on evolution, past extinctions, and perhaps even solutions to agricultural problems.
