Healing the ecosystem so the otters could come back had the win-win effect of helping manage an invasive species. "The sea otters, they're like an assistant manager for us," she said. The pattern ...
The culprit behind the ecological upheaval is a destructive and unyielding foe—an invasive species that doesn’t belong in the Everglades, but whose successful adaptation to its new environment ...
Unlike the notable ideas (concerning the success of invasive non-indigenous organisms) that preceded it, such as the enemy release hypothesis (ERH) and Charles Darwin's Habituation Hypothesis, [2] the EICA hypothesis postulates that an invasive species is not as fit (in its introduced habitat) at its moment of introduction as it is at the time that it is considered invasive.
A young cane toad. The cane toad in Australia is regarded as an exemplary case of an invasive species.Australia's relative isolation prior to European colonisation and the Industrial Revolution, both of which dramatically increased traffic and import of novel species, allowed development of a complex, interdepending system of ecology, but one which provided no natural predators for many of the ...
Saving the species was a major conservation success story. The black robin (Petroica traversi) was saved from the brink of extinction by a conservation effort led by Don Merton of the New Zealand Wildlife Service. However all black robins that survive today are descended from a single female, therefore the species has little genetic diversity.
It's hard to believe, but a little over 100 years ago, over-hunting drove Canada geese close to extinction. New York State officials decided that the birds needed help if they were to survive and ...
In a meta-analysis of 19 research studies involving 72 pairs of native and invasive plants, invasive exotic species did not incur less damage than their native counterparts and, in fact, exhibited lower relative growth rates. [23] In other cases, invasive success was due not to release from herbivory but greater tolerance of it. [24]
A gene drive could be used to eliminate invasive species and has, for example, been proposed as a way to eliminate invasive mammal species in New Zealand. [175] Briefly put, an individual of a species may have two versions of a gene, one with a desired coding outcome and one not, with offspring having a 50:50 chance of inheriting one or the other.
