This paper presents the course of events of a five-day summer camp on environmental chemistry with high emphasis on chemical analysis. The annual camp was optional and open for students of all disciplines and levels. The duration of the summer camp was five and a half days in the Feldberg Lake District in northeast Germany (federal state of Mecklenburg-Western Pomerania). The participants took part in the continuation of the examination of the lakes in the region, which leads back more than 50 years. They gained hands-on experience in environmental characterization of various lakes and classification by determining chemical, physical, and biological parameters such as phytoplankton, zooplankton, and macrophytes. Short lectures are presented by professionals covering a theoretical background of limnology, environmental chemistry, a variety of analytical methods, freshwater biology, and the specifics of the region. The camp in its present form was established in 1995, and about 20 students took part in the camp per year. Camp development, considerations regarding employed analytical methods, balance of theory, and other implications are discussed.
Bültmann, H., Roux, C., Egea, J.M., Julve, P., Bricaud, O., Giaccone, G., Täuscher, L., Creveld, M., Di Martino, V., Golubiç, S. & Takeuchi, N. Validations and descriptions of European syntaxa of vegetation dominated by lichens, bryophytes and algae. Lazaroa 36: 107-129 (2015).Fourty-two high-rank syntaxa and seven associations of the thallophyte system of syntaxa are either described as new or validated in this paper. Among those, there are the following nine classes: Aspicilietea candidae, Caulerpetea racemosae, Desmococcetea olivacei, Entophysalidetea deustae, Gloeocapsetea sanguineae, Mesotaenietea berggrenii, Naviculetea gregariae, Porpidietea zeoroidis, Roccelletea phycopsis. Eleven orders and ten alliances as well as three associations are described or validated: the Aspicilietalia verruculosae (incl. Aspicilion mashiginensis and Teloschistion contortuplicati), the Caulerpetalia racemosae (incl. Caulerpion racemosae), the Desmococcetalia olivacei (incl. Desmococcion olivacei), the Dirinetalia massiliensis, the Fucetalia vesiculosi (incl. Ascophyllion nodosi), the Gloeocapsetalia sanguineae, the Lecideetalia confluescentis (incl. Lecideion confluescentis), the Mesotaenietalia berggrenii (incl. Mesotaenion berggrenii, Mesotaenietum berggrenii and Chloromonadetum nivalis), the Naviculetalia gregariae (incl. Oscillatorion limosae and Oscillatorietum limosae), the Porpidietalia zeoroidis (incl. Porpidion zeoroidis), and the Roccelletalia fuciformis (incl. Paralecanographion grumulosae). Further, five orders, seven alliances and four associations, classified in known classes, were described as well. These include: the Bacidinetalia phacodis, the Agonimion octosporae and the Dendrographetalia decolorantis (all in the Arthonio radiatae-Lecidelletea elaeochromae), the Staurothelion solventis (in the Aspicilietea lacustris), the Pediastro duplicis-Scenedesmion quadricaudae and the Pediastro duplicis-Scenedesmetum quadricaudae (both in the Asterionelletea formosae), the Peccanion coralloidis and the Peltuletalia euplocae (both in the Collematetea cristati), the Laminarion hyperboreae, the Saccorhizo polyschidi-Laminarietum and the Alario esculenti-Himanthalietum elongatae (all in the Cystoseiretea crinitae), the Delesserietalia sanguinei, the Delesserion sanguinei and the Delesserietum sanguineae (all in the Lithophylletea soluti), as well as the the Rinodino confragosae-Rusavskietalia elegantis and the Rhizocarpo geographici-Rusavskion elegantis (both in the Rhizocarpetea geographici). , N. Descripción y validación de distintos sintáxones europeos de la vegetación dominada por briófitos, líquenes y algas. Lazaroa 36: 107-129 (2015).Se describen por primera vez o se validan un total de 42 sintáxones de alto rango y 7 asociaciones correspondientes a distintos tipos de vegetación talofítica y briofítica. Entre ellos se incluyen las 9 clases siguientes: Aspicilietea candidae, Caulerpetea racemosae, Desmococcetea olivacei, Entophysalidetea deustae, Gloeocapsetea sanguineae, Mesotaenietea berggrenii, Naviculetea gregaria...
Es wird eine Übersicht über sechs planktische und 18 benthische Mikroalgengesellschaften der Gewässer Nordostdeutschlands vorgelegt. Die Algengesellschaften sind gute Indikatoren für die Wasserqualität (Trophie und Saprobie). Eine Zusammenfassung der pflanzensoziologischen Einheiten in einem System bildet die Grundlage für ihre Nutzung zur Bioindikation.
