Hybridization between introduced and indigenous species can lead to loss of unique
genetic resources and precipitate extinction. In Tanzania, the Nile tilapia (Oreochromis …

Among the many negative impacts of invasive species, hybridization with indigenous
species has increasingly become recognized as a major issue. However, relatively few …

Adaptive divergence with gene flow often results in complex patterns of variation within taxa
exhibiting substantial ecological differences among populations. One example where this …

According to COI DNA barcoding testing, the marine bivalve mollusc Mactra chinensis,
which is native to the Asia-Pacific region, diverged into three species. These species were …

Hybrid advantage, described as the superiority of hybrids in some traits over their parents
and termed the “heterosis effect,” is widely documented in the case of reciprocal crosses of …

Background Several hypotheses have been proposed to explain parasite infection in
parental species and their hybrids. Hybrid heterosis is generally applied to explain the …

The recent focus on a common movement ecology paradigm has increased awareness
about the importance of distinguishing different movement patterns for understanding their …

Different migratory species have evolved distinct migratory characteristics that improve
fitness in their particular ecological niches. However, when such species hybridize …

Assisted gene flow is increasingly used to combat severe population declines. However, the
associated risks, such as outbreeding depression, are often insufficiently assessed. Here …

Adaptation to new ecological niches is known to spur population diversification and may
lead to speciation if gene flow is ceased. While adaptation to the same ecological niche is …
