Signs of the times: Isotopic signature changes in several fish species following invasion of Lake Constance by quagga mussels

by Patrick Canniff | Apr 5, 2022 | Uncategorized

Since the arrival of the invasive quagga mussels Dreissena rostriformis bugensis in Lake Constance, significant changes in the zooplankton and benthic invertebrate community were observed. Five years later the quagga mussel has become the dominating species of the...

Size matters? Species- and size-specific fish predation on recently established invasive quagga mussels Dreissena rostriformis bugensis Andrusov 1897 in a large, deep oligotrophic lake

by Patrick Canniff | Apr 5, 2022 | Uncategorized

Since its first appearance in Lake Constance in 2016 the invasive quagga mussel Dreissena rostriformis bugensis has come to dominate the mussel community and now occurs in hyperabundant densities over the whole lake bottom. A lake-wide field study was conducted...

Non-native Dreissena associated with increased native benthic community abundance with greater lake depth

by Patrick Canniff | Apr 5, 2022 | Uncategorized

Although the typical interaction between non-native invasive species and native species is considered to be negative, in some cases, non-native species may facilitate native species. Zebra and quagga mussels (Dreissena spp.) are aggressive invaders in freshwater...

Impact of zebra mussels on physiological conditions of unionid mussels in Texas

by Patrick Canniff | Apr 5, 2022 | Uncategorized

Zebra mussels (Dreissena polymorpha) are an invasive species known to detrimentally affect native unionid mussels, a highly imperiled group of organisms. Yet, no study has compared the impact of infestation (direct attachment to unionid mussel shells) and presence of...

Dietary contributions of the alien zebra mussel Dreissena polymorpha in British freshwater fish suggest low biological resistance to their invasion

by Patrick Canniff | Apr 5, 2022 | Uncategorized

Native communities can resist the establishment and invasion of alien species through consumptive and/or competitive interactions. The extent of consumptive resistance from freshwater fish to the invasion of zebra mussels Dreissena polymorpha, a globally invasive...

Early changes in the benthic community of a eutrophic lake following zebra mussel (Dreissena polymorpha) invasion

by Patrick Canniff | Apr 5, 2022 | Uncategorized

In the context-dependent world of biological invasions, biologists understand few general patterns of spread and impact. One possible exception is the zebra mussel (Dreissena polymorpha), an invader that routinely restructures food webs through an ecosystem...

Zebra Mussel Invasion Associated with Higher Reliance on Littoral Energy Sources and Higher Mercury Levels in Walleye and Yellow Perch

by Patrick Canniff | Apr 5, 2022 | Uncategorized

Zebra mussels (Dreissena polymorpha), an aquatic invasive species, shift lake food resources from the pelagic to the littoral zone, while simultaneously altering physical habitat by increasing water clarity. Using stable isotope analysis, we find that walleye (Sander...

Dispersal-driven coexistence in a multiple-patch competition model for zebra and quagga mussels

by Patrick Canniff | Apr 5, 2022 | Uncategorized

Zebra and quagga mussel are among the world’s notorious invasive species because of their large and widespread ecological and economic effects. Although these two species have similar life histories and share many ecological traits, they have some significant...

Variation in trophic niches of fish in Lake Powell prior to full colonization by quagga mussel (Dreissena rostriformis bugensis)

by Patrick Canniff | Apr 5, 2022 | Uncategorized

Invasive species can cause disruption of the trophic niche of resident species such that patterns of energy flow through ecological systems are altered. Quagga mussel Dreissena rostriformis bugensisAndrusov, 1897, a notorious invasive species, was introduced to Lake...

Biological control of invasive zebra mussel (Dreissena polymorpha) in a freshwater ecosystem through Potamon ibericum

by Patrick Canniff | Apr 5, 2022 | Uncategorized

In the present study, possible effects of using Potamon ibericum for the prevention of zebra mussel (Dreissena polymorpha) invasion in a freshwater ecosystem were investigated. In a recirculating aquaculture system (RAS) supplied with aerated freshwater, 3 individuals...
