TLDR
Underwater quadrats on stone substrates provide a quantitative estimation of abundance and size-structure allowing the comparisons of crayfish populations from different lakes and could be applied to assess the extent of pressure resulting from alien cray fish under the Water Framework Directive.Abstract:
Invasive alien species (IAS) potentially may alter all levels of the ecological organization of aquatic water bodies. Therefore, in the context of the EU Water Framework Directive, they represent a ...read more

TL;DR: Assays for species-specific detection and quantification of the three above mentioned crayfish species on the basis of mitochondrial cytochrome oxidase 1 (mtDNA-CO1) show promising potentials for future monitoring of A. astacus, P. leniusculus and A. leptodactylus.

Incorporating invasive alien species into ecological assessment in the context of the Water Framework Directive.
A. C. Cardoso,G. Free +1 more
TL;DR: It is proposed that the densities and distribution of invasive alien species in water bodies are matched to normative definitions for quality classes in the WFD by expert groups at EU level to allow a rapid and consistent assignment of ecological status on the basis of IAS abundance and distribution in a water body.

TL;DR: In this paper, the relative importance of environmental variables in explaining macroinvertebrate abundance was examined in 45 sub-alpine lakes were sampled for macroinvetebrates in the shallow sublittoral.

Reconstruction and prediction of invasive mongoose population dynamics from history of introduction and management: a Bayesian state-space modelling approach.
TL;DR: A hierarchical model that incorporates multiple types of data to reveal long-term population dynamics has the potential to be updated with the outcomes of control efforts, and will enhance adaptive management of invasive species.
Journal ArticleDOI
Include or exclude? A review on the role and suitability of aquatic invertebrate neozoa as indicators in biological assessment with special respect to fresh and brackish European waters
TL;DR: This paper reviews published knowledge on how to deal with invasive species during biological quality assessments in European river systems for water management and assessments of ecological quality required, for example, by the European Water Frame Work Directive.

TL;DR: This study identified a ranking of the importance of drivers of change, aranking of the biomes with respect to expected changes, and the major sources of uncertainties in projections of future biodiversity change.

Biotic invasions: causes, epidemiology, global consequences, and control

TL;DR: Given their current scale, biotic invasions have taken their place alongside human-driven atmospheric and oceanic alterations as major agents of global change and left unchecked, they will influence these other forces in profound but still unpredictable ways.

Loss on ignition as a method for estimating organic and carbonate content in sediments: reproducibility and comparability of results.
TL;DR: In this paper, five test runs were performed to assess possible bias when performing the loss on ignition (LOI) method to estimate organic matter and carbonate content of lake sediments.
Directive 2000/60/EC of the European Parliament and of The Council of 23 October 2000 establishing a Framework for Community Action in the Field of Water Policy (Water Framework Directive)
TL;DR: The declaration of the Ministerial Seminar on groundwater held at The Hague in 1991 recognised the need for action to avoid long-term deterioration of freshwater quality and quantity and called for a programme of actions to be implemented by the year 2000 aiming at sustainable management and protection of freshwater resources as discussed by the authors.
