Abstract Dreissenid mussels (including the zebra mussel Dreissena polymorpha and quagga D. rostriformis ) are among world's most notorious invasive species, with large widespread ecological economic effects. However, their long‐term population dynamics poorly known, even though these critical to determining impacts effective management. We gathered analyzed 67 (>10 yr) data sets on dreissenid populations from lakes rivers across Europe North America. addressed five questions: (1) How do...
During the unusually long European drought between 2000 and 2003, water level of large shallow Lake Balaton, Hungary (area = 596 km 2 , mean depth 3.25 m), decreased by 28%. Although food availability for zooplankton remained unchanged, fish stock declined more than mass, density populations several planktonic rotifers, cladocerans, calanoid copepodes, veligers 60‐90% simultaneously with water‐level decrease regenerated only after drought. The generally strong turbulence lake was intensified...
Abstract The impacts of species invasions can subside over time as ecosystems ‘adapt’ and invaders decline or increase additional invade. character timescales invasion provide important insights into ecosystem dynamics management. Yet long-term studies remain rare often confound invasive with coincident environmental change. One way to address this challenge is ask: what ecological changes since are recapitulated in that span a range conditions, located different regions, were invaded...
Byssate bivalves are ecosystem engineers with world-wide impact on aquatic communities through habitat forming and biofouling of hard-shelled organisms. In fresh waters, they represented by invasive Ponto-Caspian dreissenid mussels spreading throughout Europe North America. They negatively affect globally threatened unionid fouling, which deteriorates their condition survival. The appearance quagga (D. rostriformis bugensis, QM) in areas occupied zebra (Dreissena polymorpha, ZM) usually has...
Unionid mussels are globally threatened by several human disturbances, including the introduction of non-native species. Among these, biofouling zebra and quagga Ponto-Caspian origin considered to be especially detrimental unionid locomotion, filtration physical condition. The aim our study was determine compare impact dreissenid fouling and/or presence on locomotion burrowing native Unio tumidus invasive Sinanodonta woodiana , a novel invader expanding its range in Europe recent decades. We...
Abstract Dreissena rostriformis bugensis (quagga mussel, QM) has spread into areas occupied by an earlier invader, polymorpha (zebra ZM) in Europe and North America. Usually QM displaces ZM within a few years or both species coexist, although the mechanisms driving these outcomes have not been uncovered clearly. In Lake Balaton (central‐eastern Europe), displaced oligotrophic (food‐limited) basin, whereas they coexist eutrophic (food‐rich) basin. Searching for drivers of interactions...
Abstract Selective predation may affect interspecific competition between coexisting prey species. Ponto‐Caspian zebra ( Dreissena polymorpha ) and quagga mussels rostriformis bugensis have become common components of benthic communities in invaded ecosystems Europe North America, where they are exposed to by molluscivorous fish. In a pairwise food selection experiment, we examined whether an efficient predator dreissenids, the carp Cyprinus carpio ), selects two mussel species and, if so,...
Although the ecosystem transforming impact of invasive dreissenid mussels has been widely reported in short-to-mid time scale studies, little is known about contribution spent shells to sediments accumulating on lake bottom. The question whether shell production significantly reduces lifespan by increasing sedimentation rate particularly interesting those shallow lakes where calcium supply sufficient maintain high mussel biomass permanently, and alkaline water does not favor dissolution....
Abstract After introduction, the invasive bivalve dreissenids became key species in biota of Lake Balaton, largest shallow lake Central Europe. The contribution dreissenid soft tissue and shell, as biotic phases, element distribution its interaction with water upper sediment phases were examined two basins different trophic conditions spring autumn. Six metals (Ba, Cu, Fe, Mn, Pb, Zn) detected all investigated phases. In general, abundant eastern basin spring, shells western This might be...
