Culture experiment with microalgae metacommunities on effects of a regional heatwave disturbance on species diversity and turnover
No full textIn a culture experiment with microalgae metacommunities, we tested the effects of a regional heatwave disturbance on species diversity (richness, Shannon diversity) and turnover. The metacommunities consisted of three local communities with different initial community compositions. In our full factorial design, half of the metacommunities were subject to dispersal (every other day) and exposed to an experimental heatwave. Communities were sampled after 5, 12, and 21 days
Bioengineering experiment on Schiermonnikoog 2015: natural composition of diatom assemblages and biovolume measured across a mussel bed
No full textIn 2015 the Marine Ecology lab. (Eriksson Lab. at the Groningen Institute for Evolutionary Life Sciences [GELIFES], University of Groningen, The Netherlands); tested the effect of different intertidal bioengineering bivalve habitats on the sediment community. We did this by adding different small scale (0.5 by 0.5 m) bivalve assemblages to the intertidal; the treatments included blue mussel reefs, cockle beds, dead shell assemblages, different types of fencing a to protect the bivalves from bird and crab predation; and fencing controls to test for fence effects. We measured effects on sediment conditions (OM, cohesion, erosion), diatom community composition and development (species composition based on cell counts and biovolume, chlorophyll a concentrations), and infauna abundance. The field experiment in the intertidal ran from 30 April to 10 June 2015 and complementary field samples were collected around a natural blue mussel bed on the same tidal flat on 7 October 2015 (N 53.489, E 6.230 degrees)

Benthic microalgal biomass composition in experimental metacommunities
No full textBenthic microalgae species were determined microscopically with the Utermöhl counting technique. Biovolume was calculated for each species by approximating cell shapes to geometric forms using microscopic images of at least 25 cells per species
Benthic microalgal initial composition (relative abundances) and diversity in experimental metacommunities
No full textRelative abundance of benthic microalgae species was calculated based on total biomass in each initial community (A, B, and C). Species diversity measures are based on biomass data
Benthic microalgal richness and Shannon diversity in experimental metacommunities
No full textSpecies richness in the local and regional communities represents the number of different species present in the community. Shannon diversity is a diversity measure that considers both species richness and evenness in the communities and thus can inform about dominance patterns in the communities. Shannon diversity was calculated using biomass data
Benthic microalgal turnover in experimental metacommunities
No full textSpecies turnover in the different communities was calculated as the change in Bray-Curtis dissimilarity for samples of the same treatment over time. The Bray-Curtis dissimilarity matrix was calculated using biomass data. We calculated turnover values after 12 days (dissimilarity between samples of the same treatment from day 5 and 12) and 21 days (dissimilarity between samples of the same treatment from day 5 and 21)

Can gender-fairness be established in language? An evaluation of the acceptance of language change in a German speech community
No full textPhDIn 1980, the first German proposals for gender-fairness in language were published in
Germany. They suggested many gender-fair alternatives to items such as the generic
masculine, which were believed to convey androcentric or sexist meanings. Since
then critics of androcentrism in the German language, together with subsequent
antidiscrimination legislation, have instigated several linguistic changes that aim at an
equal treatment and representation of the two genders. This ongoing reform of
German is, however, primarily noticeable in the official, and especially the written,
form of German; there are effective laws that ensure the use of non-discriminatory
items in this domain. In private language, on the other hand - both spoken and written
- there appears to be less readiness to use gender-fair terms. However, until now
there has been little empirical research that investigates the extent to which people
are willing to speak and write gender-fair language in their everyday private lives.
Thus, there is little knowledge of whether speakers of German are aware of any
sexism in their language, whether they agree with the criticisms that have been made
of the androcentric aspects of their language, or whether they approve of the many
gender-fair innovations. The present case study, using a triangulation approach,
investigates these questions. The research is conducted in a local speech community
in North-Rhine Westphalia. It focuses on the inhabitants of this community as a
source of information. More generally, the study emphasises the strong but often
neglected relationship between two fields of study within sociolinguistics that are often
kept separate: 'Language and Gender'and 'Language Planning'
