Biological Invasions: Paradox Lost and Paradise Gained
A new study shows how an invasive snail species accrues elevated genetic variation for key life-history traits through multiple introductions and outcrossing to create genetically novel offspring. Furthermore, the invaders' offspring follow a unique life-history strategy that may enhance their ability to invade.
متن کاملParadox lost: genetic diversity and the success of aquatic invasions.
There is mounting evidence that reduced genetic diversity in invasive populations is not as commonplace as expected. Recent studies indicate that high propagule vectors, such as ballast water and shellfish transplantations, and multiple introductions contribute to the elimination of founder effects in the majority of successful aquatic invasions. Multiple introductions, in particular, can promo...
متن کاملFreshwater ecosystems and aquatic insects: a paradox in biological invasions.
Biological invasions have increased significantly in response to global change and constitute one of the major causes of biodiversity loss. Insects make up a large fraction of invasive species, in general, and freshwaters are among the most invaded ecosystems on our planet. However, even though aquatic insects dominate most inland waters, have unparalleled taxonomic diversity and occupy nearly ...

While the computerization of public schools and universities is highly profitable to the computer i n d u s t r y, it is also an experiment with the basic symbolic and moral foundations of mainstream We s tern cultur...

Reconciliation, on the other hand, originates in the acceptance of what befalls us. ... Whoever reconciles with the other just accepts to carry on his...
