Organic invasions are thought of to be one of many maximum threats to the integrity of such a lot ecosystems on the earth. This quantity explores the present country of marine bioinvasions, which were transforming into at an exponential expense over contemporary a long time. targeting the ecological points of organic invasions, it elucidates the various levels of an invasion strategy, beginning with uptake and shipping, via inoculation, institution and at last integration into new ecosystems. easy ecological suggestions - all within the context of bioinvasions - are lined, comparable to propagule strain, species interactions, phenotypic plasticity, and the significance of biodiversity. The authors process bioinvasions as dangers to the integrity of ordinary groups, but additionally as a device for higher figuring out primary ecological techniques. vital facets of handling marine bioinvasions also are mentioned, as are many informative case reviews from worldwide.

Sample text

The common and widespread Atlantic North American filamentous red alga, Neosiphonia harveyi (= Polysiphonia harveyi), described in 1848 from Connecticut, was not recognized as 2 Deep Invasion Ecology and the Assembly of Communities in Historical Time 31 native to Asia until the 1990s (McIvor et al. 2001). This species is further discussed below in two contexts, relative to biogeographic biases in detecting invasions, and relative to the concept of the “Missing 1000” invasions (Carlton 2000, 2002, and below).

3. An interest in establishing the scale of community alteration, in order to undertake environmental management if not actual restoration (Byers et al. 2002; Lotze et al. 2006; Chap. 21, Hacker and Dethier). The foundation of all three rationales relies not only on the ability to recognize which species are introduced (Chapman and Carlton 1991, 1994) – and thus to make an adequate estimate of the number of non-native species – but also, based on this recognition, to determining experimentally the role of invasions in regulating and producing community structure.

In some cases we are witnessing an “invasional meltdown,” in which on or a group of exotic species facilitate new invaders in various ways, increasing the likelihood of survival and possibly even the magnitude of invasion impact (Simberloff and Von Holle 1999). Although we have been much slower to realize the extent and impacts of invasions in the sea compared to those on land, our experience with problematic aquatic invasions continues to mount. The alga Caulerpa taxifolia, a popular aquarium species, now carpets many square kilometers of sea floor in the Mediterranean, a comb jelly native to the western Atlantic caused the collapse of fisheries when introduced into the Caspian Sea, and invasive marsh grasses and mangroves are transforming wetlands around the world.
