Biological invasions are a major global environmental and economic problem. Analysis of the San Francisco Bay and Delta ecosystem revealed a large number of exotic species that dominate many habitats in terms of number of species, number of individuals and biomass, and a high and accelerating rate of invasion. These factors suggest that this may be the most invaded estuary in the world. Possible causes include a large number and variety of transport vectors, a depauperate native biota, and… 

Biotic Invasions in a Mediterranean Lagoon

The invasion of an accidentally introduced bryozoan Tricellaria inopinata, which dominated the Lagoon's fouling community within seven years of its initial detection, illustrates the importance of placing invasions in the context of the hydrological, chemical and biotic changes that occur in the Lagoons environment.

Ecological and evolutionary consequences of coastal invasions

Eurasian milfoil invasion in estuaries: physical disturbance can reduce the proliferation of an aquatic nuisance species.

Biological invasions are among the most pervasive yet least understood of the con sequences of the urbanization of estuarine ecosystems. In Mobile Bay, Alabama (USA), the construction of a

An overview of species introduction and invasion processes in marine and coastal lagoon habitats

The species introduction process involves a donor region, a vector, a corridor, a recipient region, a candidate species and a variety of filters that hinder the process. All these parameters are of

Ecosystem vulnerability to alien and invasive species: a case study on marine habitats along the Italian coast

To assess the susceptibility of marine habitats to biological invasions, a dataset was gathered of the occurrence of 3899 species from 29 phyla, taken from 93 marine sites located along the Italian coast in the period 2000-2012.

Risk Analysis for Biological Invasions of the Laurentian Great Lakes and Inland Aquatic Ecosystems

by John M. Drake Biological invasions of non-indigenous species (NIS) are a severe and growing environmental problem that results primarily from introductions by humans. There are few tools for risk

Species Diversity and Invasion Resistance in a Marine Ecosystem.

In experimental communities of sessile marine invertebrates, increased species richness significantly decreased invasion success, apparently because species-rich communities more completely and efficiently used available space, the limiting resource in this system.

Biological Invasions of Marine Ecosystems: Patterns, Effects, and Management

In 1988, a small, zebra-striped mussel from the Caspian Sea was first found in North America, having successfully colonized the Great Lakes. This species had already proven itself to be a successful

Invasion Age and Invader Removal Alter Species Cover and Composition at the Suisun Tidal Marsh, California, USA

It is shown that it is important to consider invasion age, along with exotic species removal, when developing a restoration strategy in wetland ecosystems, and removal of invasive perennial pepperweed led to reinvasion of the resident plant community within two years.

Habitat Distribution and Heterogeneity in Marine Invasion Dynamics: the Importance of Hard Substrate and Artificial Structure

Artificial substrata are likely the first habitats colonized by non-native species arriving to a bay or estuary, and therefore may be focal points for the growth and spread of non- native populations.



Nonindigenous aquatic species in a United States estuary: a case study of the biological invasions of the San Francisco Bay and delta

The San Francisco Bay/Delta Estuary hosts more nonindigenous species than are known for any other estuary, with 212 established species, 15 species too recently arrived to determine whether they have

Remarkable invasion of San Francisco Bay (California, USA), by the Asian clam Potamocorbula amurensis. II, Displacement of a former community

Long-term macrobenthic sampling at a site in northern San Francisco Bay has provided an unusual opportunity for documenting the time course of an invasion by a recently introduced Asian clam Potamocorbula amurensis, and its ability to live in low salinity water suggests that P. amurnsis may not be displaced with the return of normal winter river flow and, therefore, may have permanently changed benthic community dynamics in this region of San FranciscoBay.

Zebra mussels : biology, impacts, and control

This book describes thirty years of studies of "dreissena polymorpha" pallas ecology in Mazurian lakes of northeastern Poland and the evolution and success of the heteromyarian form in the " dreissenoida".

Biological Invasions and Cryptogenic Species

It is clear that in communities that have been under the sustained influence of human endeavor there are many species that cannot reliably be assigned to either native or exotic, and the existence of cryptogenic species has important consequences for understanding biological invasions.

Patterns of Extinction in the Introduced Hawaiian Avifauna: A Reexamination of the Role of Competition

It is proposed that the following patterns are true: (1) Extinction rate as a function of number of species present (S) is not better fit by addition of an S2 term, and bill-length differences between pairs of species that invaded together may tend to be less for pairs in which at least one species became extinct.

Season of Attachment and Growth of Sedentary Marine Organisms at Oakland, California

The purpose of this paper is to present the results of studies made with test panels set out over a period of more than a year in Oakland Estuary at Oakland, California.

The Role of Competition and Introduction Effort in the Success of Passeriform Birds Introduced to New Zealand

It is suggested that a second pattern in avian invasion success previously attributed to competition, the morphological overdispersion of successful invaders, could also arise as an artifact of variation in introduction effort.

The All-or-None Pattern in Introduced Hawaiian Passeriforms: The Role of Competition Sustained

It is argued that, once corrected, the observed all-or-none pattern is consistent with the competition hypothesis, and four analyses interpreted as supporting the hypothesis that competition has influenced patterns in introduction success among these birds are criticized.

Role of substrates and products of PI 3-kinase in regulating activation of Rac-related guanosine triphosphatases by Vav.

Control of Vav in response to mitogens by the products of PI 3-kinase suggests a mechanism for Ras-dependent activation of Rac.
