„Natur muss gefühlt werden“ – Alexander von Humboldt, Vordenker einer ökologischen Weltsicht und Protagonist „transversaler Vernunft“
No full textDer Text erinnert zum 250sten Geburtsjahr an Alexander von Humboldt, ein Vordenker für eine ökologische Sicht der Welt und ein früher Protagonist „transversaler Vernunft“. Er ist als Ideengeber für die „neuen Naturtherapien“, für die Integrative Therapie und für eine ökologische Sicht in der Psychotherapie eine unverzichtbare Quelle. Einige aus dieser Perspektive wichtige Aspekte seines Denkens und Werkes werden aufgezeigt. Er ist ein Referenzautor für transversales und integratives Konzeptualisieren in unserer Zeit.The text commemorates the 250th year of birth of Alexander von Humboldt, a thought leader for an ecological view of the world and an early protagonist of „transversal reason“. He is an indispensable source of ideas for the „new nature therapies“, for integrative therapy and for an ecological viewpoint in psychotherapy. Some important aspects of his thinking and work are shown from this perspective. He is a reference author for transversal and integrative conceptualization in our time.https://www.fpi-publikation.de/polyloge/25-2019-petzold-h-g-mathias-wiedemann-u-natur-muss-gefuehlt-werden-alexander-v-humboldt/peerReviewedpublishedVersio

Coastal Mesozooplankton Assemblages during Spring Bloom in the Eastern Barents Sea
No full textMesozooplankton play an important role in Arctic shelf ecosystems as a trophic link and a key food source for many larval fish species. The distribution of mesozooplankton in the eastern Barents Sea was studied along a 500 nautical mile-long transect in May 2016 during the spring bloom. Mesozooplankton were sampled using a Juday net hauled from the surface to the bottom at 12 stations. We found good correspondence between the distribution of water masses and mesozooplankton assemblages. Mesozooplankton abundance (mean 73·103 individuals m−2) in Novaya Zemlya coastal water was dominated by Copepoda ova and nauplii, Thyssanoessa spp. nauplii and Oithona similis. Parasagitta elegans and Calanus finmarchicus comprised most of the total mesozooplankton biomass (mean 0.9 g dry mass m−2) in that water mass. A second assemblage (mean abundance 171·103 individuals m−2) was associated with the colder Barents Sea water, with Oithona similis, Copepoda nauplii, Fritillaria borealis and Cirripedia nauplii being the most numerous. In that water mass, C. finmarchicus, Metridia longa, Cirripedia nauplii and Calanus glacialis contributed most to the total biomass (mean 3 g dry mass m−2). The dominance of young stages of Copepoda and a high proportion of meroplankton were typical of spring mesozooplankton assemblages. The spatial distribution of mesozooplankton abundance and biomass was strongly correlated with latitude, longitude and chlorophyll a concentration, which together explained 10% of the total variance in mesozooplankton density. The present investigation is a baseline study for the assessment of the spring mesozooplankton assemblage in the eastern Barents Sea, and for an evaluation of the possible impact of future environmental changes on the Arctic shelf marine ecosystem
Summer mesozooplankton community of Moller Bay (Novaya Zemlya Archipelago, Barents Sea)
No full textNovaya Zemlya Archipelago is the eastern boundary of the Barents Sea. Theplankton of this region have been less intensively studied than thoseof other Arctic areas. This study of the mesozooplankton assemblage of Moller Bay was conducted in August2010. The total mesozooplankton abundance and biomass ranged from 962to 2980 individuals m-3 (mean ± SD: 2263 ± 921 indiv.m-3) and from 12.3 to 456.6 mg dry mass m-3 (mean ± SD:192 ± 170 DM m-3) respectively. Copepods and appendicularians werethe most numerous groups with Oithona similis, Pseudocalanusspp.,Acartiaspp., Calanus glacialis and Oikopleura vanhoeffennibeing the most abundant and frequent. Mesozooplankton abundance tendedto decrease with depth, whereas an inverse pattern was observed for the totalbiomass. Total mesozooplankton biomass was negatively correlated with watertemperature and positively correlated with salinity and chlorophyll aconcentration. Comparison with previous data showed significant interannualvariations in the total zooplankton stock in this region that may be due todifferences in sampling seasons, climatic conditions and the distribution ofpotential food sources (phytoplankton and seabird colonies)

Copepod Assemblages in A Large Arctic Coastal Area: A Baseline Summer Study
No full textTo provide a baseline description of copepod assemblages in the Pechora Sea, an estuarine area with great economical and ecological importance, we conducted a survey during the summer season. A total of 24 copepod taxa were identified in the study, with Acartia longiremis, Calanus finmarchicus, Centropages hamatus, Copepoda nauplii, Eurytemora affinis, Oithona similis, Pseudocalanus spp., and Temora longicornis being the most numerous. The high diversity (Shannon index = 2.51 ± 0.06), density (18,720 ± 3376 individuals m−3) and biomass (89 ± 18 mg dry mass m−3) of copepods were revealed. Populations of common small copepod taxa were dominated by the young stages, indicating spawning, while older copepodites prevailed among medium- and large-sized species, showing that their reproduction occurred before our survey. Cluster analysis indicated three groups of stations that mainly differed in the abundance of particular species. There were clear associations between copepod assemblages and environmental variables. Statistical analyses showed significant correlations between copepod abundance and water temperature or sampling depth, while other factors had a lesser influence. Our results suggest a strong effect of local circulation and currents on the spatial pattern of the copepod assemblages in the study area. This study may be useful for future biomonitoring in the south-eastern Barents Sea
