When a new plant or animal species is introduced in
an area, it often harms native species, sometimes completely taking over a
habitat. We'll hear the latest research on Why Invasive Species Succeed,
in today's Florida Environment. There's new research that confirms what many have
suspected about invasive species: that these plants and animals do better
where they're introduced, because they leave their parasites and diseases
behind. Mark Torchin is a co-author of a new study... |

When a plant or animal leaves its native habitat and invades foreign territory, what it leaves behind might be part of what enables its success elsewhere. How Invasive Species Escape their Controls, in today's Florida Environment... Parasites and disease help keep plant and animal populations in check. That's the finding of two recent research projects on invasive species. Mark Torchin is a co-author of one of the studies... |

When a plant or animal is introduced to an area where it is not native, it becomes literally an invasive species, and today's global commerce lends itself to helping those invasions. Hear about Transporting Invasive Species in today's Florida Environment When an invasive plant or introduced animal species does well in its new habitat, it is partly because of the parasites and diseases the species left behind. New research demonstrates that, and says study co-author Mark Torchin, it shows the power of the parasite... |

It has become common news: a plant or animal introduced from a distant land, taking over local territory. But new studies on dozens of plants and animals might shed some light on why they're so successful. Leaving Controls Behind in today's Florida Environment.... As a group of scientists set out to prove the relationship between the success of invasive species, and a lack of parasites that follow them to a new home, they studied dozens of animal species that have succeeded as invaders. Researcher Mark Torchin favored the European Green Crab... |

One of the greatest threats to natural lands and native species is invasive plants and animals that often out-compete their native counterparts. But new research points the way toward one way of keeping invaders in check. Help for Controlling Invaders in today's Florida Environment. In the latest research on invasive plants and animals, scientists have proven the link between successful invaders and their escape from the parasites and diseases that kept them in check in their native lands. Mark Torchin is co-author of one of the new studies, which he says demonstrates that parasites are part of the solution... |
