The Laurentian Great Lakes basin has been invaded by at least 182 non-indigenous species. A new invader is discovered every 28 weeks, which is the highest rate recorded for a freshwater ecosystem. Over the past century, invasions have occurred in phases linked to changes in the dominant vectors. The number of ship-vectored invaders recorded per decade is correlated with the intensity of vessel traffic within the basin. Ballast water release from ocean vessels is the putative vector for 65% of all invasions recorded since the opening of the St. Lawrence Seaway in 1959. As a preventive measure, ocean vessels have been required since 1993 to exchange their freshwater or estuarine ballast with highly saline ocean water prior to entering the Great Lakes. However, this procedure has not prevented ship-vectored species introductions. Most ships visiting the Great Lakes declare 'no ballast on board' (NOBOB) and are exempt from the regulation, even though they carry residual water that is discharged into the Great Lakes during their activities of off-loading inbound cargo and loading outbound cargo. Recently introduced species consist predominantly of benthic invertebrates with broad salinity tolerance. Such species are most likely to survive in a ballast tank following ballast water exchange, as well as transport in the residual water and tank sediments of NOBOB ships. Thus, the Great Lakes remain at risk of being invaded by dozens of euryhaline invertebrates that have spread into Eurasian ports from whence originates the bulk of foreign ships visiting the basin.

“…It is common in loworder streams of preserved areas (Armendáriz & César 2001, Gorni & Alves 2008b, lakes (Spencer & Hudson 2003) and associated with submersed macrophytes ). According to Martínez-Ansemil (1984), it has affinity for moderate to fast currents.…”

Inventory and distribution of Oligochaeta (Annelida, Clitellata) in first-order streams in preserved areas of the state of Minas Gerais, Brazil

2013

Data resulting from species inventories shed light on the richness and distribution of various groups. In Minas Gerais, work on inventory and distribution of the oligochaetes of lotic environments in preserved areas are non-existent. Therefore, this study aimed to inventory the limnic oligochaetes fauna of first-order streams located in four preserved areas, to expand knowledge of the ecology and distribution of this group. In total, 19 taxa were inventoried, belonging to the families Naididae and Enchytraeidae and the superorder Megadrili (earthworms), with the genus Pristina having the largest number of species. The number of species found in this investigation corresponds to 22% of oligochaetes species recorded in Brazilian aquatic environments. The results obtained add important knowledge of the distribution of some oligochaetes species in Brazil, represent the first records of species for the four preserved areas studied and confirm the first occurrence of various species in the state.

Inventário e distribuição de Oligochaeta (Annelida,Clitellata) em córregos de primeira ordem localizados em áreas preservadas do estado de Minas Gerais, Brasil. Biota Neotrop. 13(1): http://www.biotaneotropica.org.br/v13n1/pt/abstract?inventory+bn02313012013Resumo: Os dados resultantes de um levantamento fornecem informações sobre a riqueza e distribuição de diversos grupos. Em Minas Gerais, trabalhos sobre inventário e distribuição de oligoquetas de ambientes lóticos em áreas preservadas são inexistentes. Dessa forma, este estudo objetivou inventariar a fauna de oligoquetas límnicos de córregos de primeira ordem localizados em quatro áreas preservadas, visando ampliar as informações sobre ecologia e distribuição deste grupo. Foram inventariados 19 taxa pertencentes às famílias Naididae, Enchytraeidae e à superordem Megadrili, sendo o gênero Pristina o de maior número de espécies. O número de espécies encontradas neste trabalho corresponde a 22% das espécies de oligoquetas registrados em ambientes aquáticos brasileiros. Os resultados obtidos ampliam o conhecimento sobre a distribuição de algumas espécies de oligoquetas no Brasil, representam os primeiros registros de espécies para as quatro áreas preservadas estudadas e confirmam a primeira ocorrência de várias espécies no Estado. Palavras-chave : biodiversidade, Campos Rupestres, Mata Atlântica, Naididae, folhiço, oligoquetas, Enchytraeidae. Martins et al. ( , 2011 and Suriani-Affonso et al. (2011), the number in the state has increased to 23. The true number is probably even higher, because ecological studies often record new species not considered in official records. In this context, the present study aimed to inventory the limnic oligochaete fauna in first-order streams in preserved areas, to expand the information about the ecology and distribution of this group.

“…vejdovskyi (Hrabe, 1941). For instance, the latter two species are well established in the Great Lakes of North America, while the records of P. hammoniensis from these lakes have shown to be erroneous (Spencer & Hudson 2003). Another widely distributed, and probably also spontaneously established species in Sweden, P. bedoti (Piguet, 1913), may have remained unnoticed in our rivers, as it mostly reproduces asexually.…”
