1. Prohibiting pet crayfish does not consistently reduce their availability online
Abstract The pet trade is a significant source of introductions of non-indigenous aquatic species, such as crayfish. To test whether legislation that regulates the ownership of ornamental animals for aquariums had the desired effect of reducing the availability of those pets, classified advertising websites were monitored for sales of crayfish in jurisdictio

2. Invading the natural marine substrates: a case study with invertebrates in South Brazil
ABSTRACT The number of biological invasions has grown dramatically in recent decades, as well as the world's human population and coastal development. Anthropogenic habitats, such as pier pilings and break waters, have been constantly added to marine environment, usually concentrated in estuarine areas. These habitats are focal points for marine invasions, b

3. Multiple introductions and gene flow in subtropical South American populations of the fireweed, Senecio madagascariensis(Asteraceae)
Abstract Non-indigenous plants exhibit different attributes that make them aggressive competitors with indigenous plants and serious threats to biodiversity.Senecio madagascariensis (fireweed, Asteraceae), a native from southern Africa, is a strong competitor in agricultural activities and has toxic alkaloids that may result in high cattle mortality. In Braz

4. The non-indigenous bryozoan Triphyllozoon (Cheilostomata: Phidoloporidae) in the Atlantic: morphology and dispersion on the Brazilian coast
ABSTRACT Bryozoans constitute an important component of marine-fouling communities of anthropogenic substrata. Many species have been reported as exotic or widespread around the world, typically in ports and harbors of non-polar regions. Here we present the first record of a species of the bryozoan Triphyllozoon in the Atlantic Ocean. Triphyllozoon arcuatum

5. Potential Use of Polysaccharides from the Brown Alga Undaria pinnatifida as Anticoagulants
Undaria pinnatifida (U. pinnatifida) is a highly invasive species and has caused concern all over the world because it has invaded coastal environments, has the potential to displace native species, significantly alters habitat for associated fauna, and disturbs navigation. Any attempt to eradicate it would be futile, owing to the elusive, microscopic gameto

6. Detection of introduced sessile species on the near shore continental shelf in southern Brazil
Invasion by marine species, often considered a grave threat to marine ecosystems, occurs throughout the world as a consequence of many anthropogenic activities. In coastal Paraná, many factors including shipping, aquaculture and the use of artificial substrates provide suitable environments for the establishment and rapid spread of introduced marine species

7. O Porto do Rio de Janeiro sob o enfoque da água de lastro / Ballast water in Rio de Janeiro port
A introdução de espécies exóticas nos ecossistemas marinhos, estuarinos e de água doce já é realidade em muitos locais do globo. Apesar de existirem diferentes mecanismos de dispersão de espécies exóticas, que variam tanto espacialmente quanto temporalmente, o movimento global da água de lastro é o vetor de transferência mais importante na atual

8. Evidence of hybridity in invasive watermilfoil (Myriophyllum) populations
Invasions of nonindigenous species have caused ecological devastation to natural communities worldwide, yet the biological bases for invasiveness remain poorly understood. Our studies of invasive watermilfoil (Myriophyllum) populations revealed widespread polymorphisms in biparentally inherited nuclear ribosomal DNA sequences, which were not detected in popu

9. On the pattern of discovery of introduced species
Introductions of nonindigenous species can have significant effects. It is commonly claimed that the rate of species introductions to the United States has increased over time. This claim is based in part on the increasing rate of discoveries of introduced species. This discovery rate is influenced by factors other than the introduction rate. These include t

10. Bacterioplankton community structure and dynamics after large-scale release of nonindigenous bacteria as revealed by low-molecular-weight-RNA analysis.
A set of freshwater mesocosms (1.7 m3 each) was inoculated with large amounts of Escherichia coli, Pseudomonas putida, and their culture medium to substantially disturb the natural microbial community. To monitor microbial community dynamics, low-molecular-weight RNA (5S rRNA and tRNA) obtained directly from bacterioplankton was analyzed by using high-resolu

11. Linking climate change and biological invasions: Ocean warming facilitates nonindigenous species invasions
The spread of exotic species and climate change are among the most serious global environmental threats. Each independently causes considerable ecological damage, yet few data are available to assess whether changing climate might facilitate invasions by favoring introduced over native species. Here, we compare our long-term record of weekly sessile marine i

12. Invasion of a rocky intertidal shore by the tunicate Pyura praeputialis in the Bay of Antofagasta, Chile
Invasion by marine nonindigenous species (NIS) is a spread phenomenon. The tunicate Pyura praeputialis shows pronounced disjoint geographical distribution: along thousands of kilometers in wave-swept headlands on the southeastern coast of Australia, from where it appears to have originated, and exclusively along 60–70 km inside the Bay of Antofagasta, Chil
