- Reliable taxonomy underpins communication in all of biology, not least nature conservation and sustainable use of ecosystem resources. The flexibility of taxonomic interpretations, however, presents a serious challenge for end-users of taxonomic concepts. Users need standardised and continuously harmonised taxonomic reference systems, as well as high-quality and complete taxonomic data sets, but these are generally lacking for non-specialists. The solution is in dynamic, expertly curated web-based taxonomic tools.The Pan-European Species-directories Infrastructure (PESI) worked to solve this key issue by providing a taxonomic e-infrastructure for Europe. It strengthened the relevant social (expertise) and information (standards, data and technical) capacities of five major community networks on taxonomic indexing in Europe, which is essential for proper biodiversity assessment and monitoring activities. The key objectives of PESI were: 1) standardisation in taxonomic reference systems, 2) enhancement of the quality and completeness of taxonomic data sets and 3) creation of integrated access to taxonomic information.This paper describes the results of PESI and its future prospects, including the involvement in major European biodiversity informatics initiatives and programs.

- Biological invasions offer fertile grounds for studying evolutionary ecology because species’ contact histories are uncharacteristically well-defined. As a result, invasions can be used to gain glimpses of the earliest micro-evolutionary responses of natural populations to new species’ interactions by studying changes in behaviour, physiology or morphology in space and time. Here, the known history of range expansion by the European green crab Carcinus maenas in North America is used to illustrate factors affecting invasion success and the resilience of native American prey. We situate our discussion in the bourgeoning field of adaptive phenotypic plasticity. Phenotypic plasticity is the phenomenon where an individual’s genotype interacts with its environment to produce better-fit behaviour, physiology, morphology, or life-history. Plasticity is considered adaptive when the environmentally-induced phenotype increases an individual’s fitness. Below, theory about phenotypic plasticity is reviewed as to why it may benefit invasive species in general and specifically Carcinus maenas. The plasticity-invasion hypothesis (i.e., biological invaders benefit from high levels of phenotypic plasticity) is then tested directly by comparing known levels in C. maenas and other invaders to plasticity in a diversity of non-invasive, marine invertebrates. This study also analyses whether phenotypic plasticity has helped North American prey species defend against escalated bouts of predation caused by the C. maenas invasion, and elucidates the role plasticity plays in an apparent case of predatorprey coevolution between C. maenas and at least one species of native gastropod, Littorina obtusata. Finally, knowledge gaps in the case studies presented are discussed along with suggestions for future research aimed at gaining a better appreciation for how plasticity guides phenotypic evolution after a biological invasion.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Within the generic scope of the Regional Assessments of Biodiversity and Ecosystem Services, the key policy‑relevant questions of the Europe and Central Asia Assessment concern options and opportunities with regard to biodiversity and ecosystem services and their role for human well-being. The assessment examines the opportunities for sectoral policies and policy instruments; managing production, consumption and economic development; and ecological infrastructures and ecological technologies. It explores opportunities to promote food security, economic development and equality while avoiding land and aquatic degradation and conserving cultural landscapes.
