“…In the case of Lake Erie, dreissenid mussels (both zebra and quagga mussels) have colonized a considerable portion of the lake bottom (~70%), including both hard and soft substrata (Dermott & Munawar 1993, Haltuch et al 2000. Although currently there are no estimates of filtering impacts by dreissenid mussels in the central basin, estimates by MacIsaac et al (1992) suggest that the mussels could filter 14 times the volume of the western basin in just 1 d. With this in mind, it is likely that dreissenids have increased the rate of P recycling back into the water column by filtering planktonic materials and excreting nutrients (Nichols et al 1999) that would otherwise be lost to benthic sediment.…”

Phosphorus (P) has been identified as the primary nutrient limiting phytoplankton biomass in the Laurentian Great Lakes, and thus phytoplankton biomass varies as a function of P loading. While management efforts have reduced point sources of P, a recent rise in non-point source loadings and the introduction of dreissenid mussels to the Great Lakes are factors suspected to have direct and indirect impacts on nutrient cycling. We re-evaluated nutrient limitation of phytoplankton in the central basin of Lake Erie over spatial (i.e. 3 offshore stations) and temporal (i.e. monthly from June to October) scales. The nutrient limitation of the phytoplankton was evaluated using biomass response measurements to nutrient enrichment bioassays in a complete factorial of P, nitrogen (N), and silicon (Si). Nutrient additions yielded classic growth curves after 7 to 12 d of incubation. Treatments with added P had higher final biomass yields than treatments without P at all stations and during all months. During spring overturn, P+ Si yielded higher phytoplankton biomass than did P additions without Si at 2 of the 3 stations. During the late stratification to autumn overturn (August to October), P+N promoted higher phytoplankton biomass than did P additions without N; this was true at all stations. A quantitative assessment of the bioassays indicated that 63 to 94% of the biomass yield during spring overturn could be attributed to Si, while 48 to 68% of the biomass yield during late stratification and autumn overturn could be attributed to N. Water chemistry data collected in 2002 and 2003 predicted similar seasonal trends in nutrient limitation. These results suggest that seasonal variation in phytoplankton nutrient limitation is a probable factor in predicting changes in phytoplankton biomass and taxonomic composition in the central basin of Lake Erie.

Moreover, the Great Lakes Fisheries Commission (GLFC) recognizes that, since the enactment of TP controls and the introduction of non-native dreissenids, many of the changes at the lower trophic levels appear to have influenced both the composition and productivity of the fish communities in the lake, yet little is known about the response at lower trophic levels (GLFC 1998).Nutrient enrichment bioassays have been widely used to evaluate nutrient limitations of phytoplankton (Lin & Schelske 1981). Therefore, we implemented 2 × 3 factorial nutrient enrichment bioassays (NEB) experiments using natural phytoplankton assemblages from Lake Erie to achieve 3 objectives. First, we evaluated the main and interactive effects of P, N, and Si in regulating phytoplankton biomass. Second, we characterized the seasonal and spatial variation of phytop...

“…Native unionids and macrophytes are also common substrates for zebra mussel colonization (Lewandowski, 1976, Ricciardi et al, 1996, Diggins et al, 2004. Over time, adult zebra mussels also started to use soft sediments (Haltuch et al 2000, Jones & Ricciardi 2005, but again preferably colonized hard substrate and their density was determined by substrate size (Dermott & Munawar 1993, Mellina & Rasmussen 1994, Karatayev et al 1998, Jones & Ricciardi 2005. In the St. Lawrence River, 10 years after invasion, substrate size accounted for 20% of the variation in zebra mussel biomass (Jones & Ricciardi 2005).…”

“…Neary & Leach (1992) evaluated the zebra mussel colonization risk with a GIS and mapped the potential spread of the species in Ontario by matching mussel tolerances to pH and Ca to data from 6 151 lakes. Other authors also use GIS to predict the spatial distribution of zebra mussel (Doll, 1998;Koutnik & Padilla, 1994;Haltuch et al, 2000). The goal of the present project was to determine the risk of zebra mussel infestation in water bodies in the North-West region of Bulgaria by combining available biological and environmental data and by subsequent processing and analyzing of these data using Geographic Information System.…”

R&D 1021-EN-01/ Assessment of Zebra Mussel (Dreissena polymorpha) Infestation Risk Using GIS for Water Basins in the North-West Bulgaria; Final Report, November 2006 -November 2007 AbstractIn Bulgaria, zebra mussel (Dreissena polymorpha) occurred originally in the Danube River and the Black Sea coastal lakes and rivers. During the last 10 years a rapid spread of this species in the inland water bodies has been observed. Two of the reservoirs in the North-West Bulgaria have been reported as infested. The goal of the present study was to determine the risk of zebra mussel infestation in this region by combining available biological and environmental data and by subsequent processing and analyzing of these data using Geographic Information System (GIS). This will be the first step in developing an action plan for vulnerable regions in Bulgaria.The evaluation of physical and chemical characteristics of water bodies and their suitability to the zebra mussel requirements was made based on existing data from monitored river stations, spatial data and reservoir field survey. Fifteen reservoirs were sampled to determine which physicochemical variables explain the occurrence and abundance of zebra mussel. The principal component analysis used showed that the first two principal components related mainly to calcium concentration, pH, electroconductivity and Secchi disk transparency, explained the majority of total variance of data. pH, calcium concentration and dissolved oxygen were selected as habitat suitability parameters, and corresponding tolerance ranges based on the environmental requirements of zebra mussels during the larval and early growth stages, were defined. These parameters were divided into three main categories that reflected the infestation potential of zebra mussel: Low, Moderate and High. After all spatial and attributive data were collected, they were processed and analyzed in a GIS environment, which included the GIS database development, spatial and geostatistical interpolation of limiting factors, reclassification and overlay.The results showed that based on water chemistry, 63.81% of the territory can be classified with high potential, 15.45% -with moderate potential, and 20.74% -with low po...

“…A modelação espacial da adequabilidade para espécies invasoras tem-se baseado sobretudo nestas ferramentas e metodologias (Peterson e Vieglais, 1999;Haltuch et al, 2000;Underwood et al, 2004;Ficetola et al, 200); no entanto, um aspecto essencial diverge da abordagem geral destes modelos e da modelação de habitats potenciais para espécies exóticas invasoras, que se prende com o pressuposto de que as espécies nativas se encontram em equilíbrio com o ecossistema (Guisan e zimmerman, 2000). O facto de o período temporal de interacção com o meio ser muitas vezes reduzido, leva a que em muitos casos as espécies invasoras não tenham ainda sido confrontadas com todas as adversidades que este lhes pode imputar, reduzindo as suas áreas de colonização.…”

Resumo -A modelação de habitats potenciais para espécies nativas encontra--se já bastante divulgada, sendo numerosos os exemplos existentes. Uma abordagem metodológica semelhante, mas com suporte teórico diferente é a sua realização para espécies exóticas invasoras. Este trabalho apresenta uma metodologia de modelação espacial da adequabilidade de habitat ao Chorão-de-praia (Carpobrotus edulis), uma planta exótica invasora, na Serra do bouro em Portugal. Para isso foi efectuado um levantamento de presenças desta espécie, optimizado pela sua persistência e manifestação de invasão. Conjuntamente foram criados registos de pseudo-ausência, de forma a permitir a utilização de uma regressão logística, que se considera apresentar melhores resultados preditivos do que modelos de presença apenas. É proposta uma metodologia de validação, que conjuga a área mínima de adequabilidade máxima com a quantidade de registos de validação correctos. Para esta, e considerando-se um limiar de probabilidade de 0,, obtiveram-se 80% de presenças correctas para uma área correspondente a apenas 8% da área total. O abandono agrícola foi identificado como factor potenciador da sua expansão, em conjugação com reduzidas distâncias à linha de costa e áreas sujeitas a erosão moderada. Inversamente, áreas interiores, ou com elevados declives e vertentes extensas, revelaram uma reduzida adequabilidade para a espécie. Palavras-chave: Espécies invasoras, modelação, SIG, adequabilidade de habitat.Abstract -sPAtiAl modelling of HAbitAt suitAbility foR invAsive sPeCies: tHe Carpobrotus Edulis in A non-dune AReA. The use of habitat modelling for exotic invasive species can be extremely useful for identifying their potential impacts and for assisting in the design of eradication strategies. Even though the latter builds on theoretical assumptions that are quite different from those involved in the modelling of the habitat of native species, these two modelling methods are in fact quite similar. This article presents a habitat suitability modelling framework for Carpobrotus edulis, an alien invader plant in Serra do bouro, Portugal. Several land surveys have been carried out in the study area in order to record the presence of this plant. The criteria for recording a presence were that the plant did not show any signs of weakness and that there were mat formations covering at least 5m 2 . Pseudo-absences were also obtained in a completely random way. The model was calibrated using a binary logistic regression. The performance of this model usually considered superior to that of models that rely on presence data only. Additionally, an evaluation technique based on the minimum area of higher adequacy is also presented. This technique assumes that, for a given probability threshold, model performance is higher whenever it has the same number of correct presences for a smaller predicted area. Using a 0. probability threshold, the model correctly predicted 80% of the total presences using only 8% of the study area. The model suggests that the main factor con...
