Copy number variations (CNVs) are a pervasive form of genomic variation that entail duplications or deletions of DNA segments ranging from kilobases to megabases. In animal genomes, CNVs contribute ...
Scientists studied puddle frogs to identify genetic variation hotspots and places where the climate crisis could wipe out populations too homogenous to adapt Even widespread species could be ...
Behavioral variation in animals is often influenced by experience. Previous studies have found that daily threatening experiences can enhance fear- and anxiety-like behaviors in some vertebrates.
