This article summarises the current information about the species’ systematics and phylogeny, its distribution and status as well as about its life history strategy and genetic population structure and based on this information, integrative conservation strategies for freshwater mollusc species which combine genetic and ecological information are discussed.
Integrative freshwater ecology and biodiversity conservation
Abstract Freshwater ecosystems provide goods and services of critical importance to human societies, yet they are among the most heavily altered ecosystems with an overproportional loss of
Invasive species in Europe: ecology, status, and policy
The impacts of invasive species in Europe are described, the difficulties involved in reducing these impacts, and the policy options currently being considered, and some rules of thumb for designing and implementing management programs are suggested.
Bigger Is Better: Characteristics of Round Gobies Forming an Invasion Front in the Danube River
The pronounced changes in fish and invertebrate communities with a dominance of alien species suggest invasional meltdown and a shift of the upper Danube River towards a novel ecosystem with species that have greater resistance to goby predation.
Comparative feeding ecology of invasive Ponto-Caspian gobies
Trophic niches in both species expanded during the growth period with increasing intraguild predation and cannibalism in P. kessleri and increasing molluscivory in N. melanostomus.
Genetic diversity and differentiation of central European freshwater pearl mussel (Margaritifera margaritifera L.) populations: implications for conservation and management
The genetic structure of 24 freshwater pearl mussel populations originating from five major central European drainages including Elbe, Danube, Rhine, Maas and Weser is investigated, representing the last and most important populations in this area.
Physicochemical stream bed characteristics and recruitment of the freshwater pearl mussel (Margaritifera margaritifera)
Together measurements of penetration resistance, depth gradients of Eh and texture were most suitable for assessing stream bed quality, while water chemistry was insufficient because of the decoupling of interstitial and free-flowing water at poor quality sites.
The effects of weirs on structural stream habitat and biological communities
Summary 1. Most of the world’s rivers are affected by dams and weirs. Information on the quantitative and qualitative effects of weirs across biological communities is crucial for successful
A critical reflection on the success of rearing and culturing juvenile freshwater mussels with a focus on the endangered freshwater pearl mussel (Margaritifera margaritifera L.)
Based on the rearing techniques applied for multiple species in North America, and for the genus Margaritifera in European countries, sufficient numbers of juveniles can be produced to sustain selected populations, however, captive breeding and stocking should be carefully documented and must not replace the restoration of functional stream habitats.
Ecological indicators for stream restoration success
Abstract Exploitation of freshwater resources is essential for sustenance of human existence and alteration of rivers, lakes and wetlands has facilitated economic development for centuries.
