Die abgegrenzten ABSP-Einheiten stellen im Regelfall Biotopkomplexe dar, so dass meist mehrere Entwicklungsziele zugeordnet werden. Das prioritäre Entwicklungsziel, das sich inhaltlich in der Regel nach dem höchst wert gebenden Merkmal richtet, wurde dabei an den Anfang der Aufzählung gestellt. Beispiele: Eine ABSP-Einheit beinhaltet einen Magerwiesenkomplex, in dem oligotrophe Nasswiesen mit ihrem Artenspektrum das für die Bewertung ausschlagende Merkmal darstellen. In diesem Fall steht das Entwicklungsziel "Nasswiesen" an erster Stelle und gilt somit als prioritär.

The BMDV network of experts commissioned a comprehensive terrestrial biodiversity assessment of the Hamburg harbor area, enlisting local experts to conduct the surveys. This research focused on evaluating the harbor's ecological significance for both indigenous and non-native species. Surveys were conducted between 2018 and 2021. The study employed standardized methodologies for floristic mapping and habitat classification, ensuring consistency with established protocols of the Free and Hanseatic City of Hamburg and the Federal Institute of Hydrology (BfG). For this study, habitat type data from previous surveys (1983, 2005) could be mobilized, digitized and included in the analysis. Floristic mapping adhered to the city state's survey methods and metadata standards, which allowed comparisons with available data from 1975 onwards. Methodological details pertaining to the collection of zoological data are available in the accompanying publication and followed established standards for each taxonomic group (Coleoptera, Aculeata, Formicidae, Araneae, Opiliones, Culicidae).
The Gurile Dunarii 1979 dataset contains zooplankton data collected in May and September 1979 in 13 station allong 3 transect in front of the Danube Delta (45°05' – 44°45'N, 30°02'– 29°27'E). Zooplankton sampling was undertaken at 13 stations where samples were collected using a Juday closing net in the 0-10, 10-20, 20-30, 30-40 and 40-50m layer (depending also on the water masses). The dataset includes samples analysed for mesozooplankton species composition and abundance. Sampling volume was estimated by multiplying the mouth area with the wire length. Taxon-specific mesozooplankton abundance was count under microscope. Total abundance is the sum of the counted individuals. Total biomass Fodder, Rotifera , Ctenophora and Noctiluca was estimated using a tabel with wet weight for each species an stage.
Megafauna plays an important role in benthic ecosystems and contributes significantly to benthic biomass in the Arctic. The distribution is mostly studied using towed cameras. Here, we compare the megafauna from two sites located at different distances from the Kongsfjord: one station at the entrance to the fjord, another on the outer shelf. Although they are only located 25 km apart and at comparable depth, there were significant differences in their species composition. While the inshore station was characterized by shrimps (2.57 +/- 2.18 ind./m**2) and brittlestars (3.21 +/- 3.21 ind./m**2), the offshore site harboured even higher brittlestar densities (15.23 +/- 9.32 ind./m**2) and high numbers of the sea urchin Strongylocentrotus pallidus (1.23 +/- 1.09 ind./m**2). Phytodetrital concentrations of the upper sediment centimetres were significantly higher inshore compared with offshore. At a smaller scale, there were also differences in the composition of different transect sections. Several taxa were characterized by a patchy distribution along transects. We conclude that these differences were caused primarily by habitat characteristics. The seafloor inshore was characterized by glacial soft sediments, whereas the station offshore harboured large quantities of stones. Although the use of a new web-2.0-based tool, BIIGLE (http://www.BIIGLE.de), allowed us to analyse more images (~90) than could have been achieved by hand, taxon area curves indicated that the number of images analysed was not sufficient to capture the species inventory fully. New automated image analysis tools would enable a rapid analysis of larger quantities of camera footage.
Es wird die Zusammensetzung des Artenspektrums des Bodensees untersucht, die Artenverteilung und die raeumliche Entwicklung der Artenzusammensetzung. Je nach Entwicklungsstand werden in Abstaenden von 10-30 Tagen Proben aus der Wassertiefe von 1-10 m entnommen. Die Planktonproben werden nach Fixierung am umgekehrten Mikroskop ausgezaehlt. Es wurde eine Artendokumentation angelegt, die zur Zeit ca. 120 Algenarten enthaelt. Besondere Beachtung sollen kuenftig die sogenannten my-Algen finden, die in den bis jetzt bekannten Untersuchungen kaum beruecksichtigt wurden. Das Vorhaben gliedert sich in zwei Unterabteilungen; 1. Es wird das Phytoplankton des Bodensee-Pelagials untersucht. An sieben Messpunkten, die auf einer gedachten Laengsachse durch den Bodensee liegen, werden Proben entnommen. 2. Es werden die Zusammenhaenge zwischen Phytoplanktonentwicklung in Ufernaehe und im Freiwasser untersucht. Dazu werden aus zwoelf Stellen, die ueber das gesamte Bodenseeufer verteilt sind, Proben entnommen.
The analysis of decades of data series on the occurrence of penguins and seabirds in Maxwell Bay contributes to the understanding of the effects of climate change on the marine ecosystems in the area of the northern Antarctic Peninsula. The species spectrum of penguins is shifting further in unfavour of the "true" Antarctic species, while sub-Antarctic penguins continue to increase in population. The availability of food appears to play a causal role in this, which in turn depends on the extent of sea ice. These and other results were obtained by polar researchers from Jena by analysing a data set on breeding birds, some of which they collected themselves over a period of around 40 years. This study is based on one of the longest data sets of the entire Antarctic and is therefore a milestone in polar environmental monitoring. Veröffentlicht in Texte | 63/2025.

Bunaken National Park has been surveyed for a fourth time in 14 years, in an attempt to establish the species composition of heterobranch sea slugs in a baseline study for monitoring programs and protection of this special park. These molluscs are potentially good indicators of the health of an ecosystem, as many are species-specific predators on a huge variety of marine benthic and sessile invertebrates from almost every taxonomic group. Additionally, they are known to contain bio-compounds of significance in the pharmaceutical industry. It is therefore of paramount importance not only to document the species composition from a zoogeographic point of view, but to assist in their protection for the future, both in terms of economics and aesthetics. These four surveys have documented more than 200 species, with an approximate 50% of each collection found only on that survey and not re-collected. Many species new to science have also been documented, highlighting the lack of knowledge in this field. These dataare used in the article "Marine Heterobranchia (Gastropoda, Mollusca) in Bunaken National Park, North Sulawesi, Indonesia—A Follow-Up Diversity Study" (https://doi.org/10.3390/d10040127).
