The European Polysaccharide Network of Excellence (EPNOE) research roadmap 2040: Advanced strategies for exploiting the vast potential of polysaccharides as renewable bioresources.

Polysaccharides are among the most abundant bioresources on earth and consequently need to play a pivotal role when addressing existential scientific challenges like climate change and the shift from fossil-based to sustainable biobased materials. The Research Roadmap 2040 of the European Polysaccharide Network of Excellence (EPNOE) provides an expert's view on how future research and development strategies need to evolve to fully exploit the vast potential of polysaccharides as renewable bioresources. It is addressed to academic researchers, companies, as well as policymakers and covers five strategic areas that are of great importance in the context of polysaccharide related research: (I) Materials & Engineering, (II) Food & Nutrition, (III) Biomedical Applications, (IV) Chemistry, Biology & Physics, and (V) Skills & Education. Each section summarizes the state of research, identifies challenges that are currently faced, project achievements and developments that are expected in the upcoming 20 years, and finally provides outlines on how future research activities need to evolve.

Thirteen new species of Agromyzidae (Diptera) from the United States, with new host and distribution records for 32 additional species.

We present novel rearing records of Agromyzidae (Diptera) from throughout the United States. We describe leaf mines or other larval habits for 27 species, plus five others whose identification is tentative, and another five that are identified only to genus due to the absence of male specimens. We review host and distribution data for the known species, reporting 26 new host species records (including the first rearing records for Phytomyza flexuosa Spencer, P. notopleuralis Spencer, and (tentatively identified) Ophiomyia frosti Spencer) and 25 new state records (including the first USA records for P. krygeri Hering, P. thermarum (Griffiths), and (tentatively identified) Liriomyza cracentis Lonsdale). We also describe and provide natural history information for the following 13 new species: Haplopeodes loprestii Eiseman Lonsdale, Liriomyza euphorbivora Eiseman Lonsdale, L. hypopolymnia Eiseman Lonsdale, Melanagromyza arnoglossi Eiseman Lonsdale, M. gentianivora Eiseman Lonsdale, M. hieracii Eiseman Lonsdale, M. rudbeckiae Eiseman Lonsdale, M. urticae Eiseman Lonsdale, M. verbenivora Eiseman Lonsdale, Ophiomyia nabali Eiseman Lonsdale, O. rugula Eiseman Lonsdale, Phytomyza flavilonicera Eiseman Lonsdale, and P. triostevena Eiseman Lonsdale.
