“…This may in part result from the inability of the current macrophyte scheme to take growth form or the nature of substrates into account-factors on which invertebrate communities are highly dependent. These findings are supported by a growing number of terrestrial studies that show that there is little correlation between invertebrate assemblages and NVC (National Vegetation Classification) communities and other vegetation groupings (Fishpool and Usher, 1989;Holmes et al, 1993). They also reinforce the concern, voiced by Usher (1986), of the use in conservation of the unproven assertion that if you look after the plant communities the animals will look after themselves.…”

ABSTRACT1. Littoral microcrustacean (Ctenopoda, Anomopoda, Onchyopoda) samples, aquatic macrophyte data and chemical measurements were collected from 5 1 freshwater lochs in the Isle of Skye, Scotland, during the summer of 1989.2. Canonical correspondence analysis was employed to investigate correlations between the environmental data, the microcrustacean assemblages, and the aquatic macrophyte community types used for floristic classification of standing waters. Cluster analysis was used to classify lochs based on their microcrustacean assemblages.3. The major trends in microcrustacean distributions were related to pH, catchment area, macrophyte diversity and the distance from the sea.4. There was little correlation between the plant community types and microcrustacean assemblages. 5 . These results support the case for the development of an integrated approach to lake surveys so that correlations can be made between environmental variables and the distribution and abundance patterns of the plant and animal taxa of conservation interest.

“…Scattered studies on the relationships between invertebrates and protozoans and the ecological factors in different mires suggest that water table depth is one of the chief determinants of species assemblages (Holmes et al 1993;Charman 2002, pp. 66-67 and references therein).…”

Loss of palsa mires in Europe and biological consequences

2004

SUMMARYPalsa mires are northern mire complexes with permanently frozen peat hummocks. These are degrading throughout their distribution range, probably because of regional climatic warming. This review of the current understanding of the geographical, climatic and biological characteristics of palsa mires focuses on Europe. Recent studies have reported a drastic decrease in the extent of palsa mires in Fennoscandia; in Finland, the distribution of palsas was formerly about three times that at present. With continued or accelerated warming, as predicted for high latitudes, further extensive degradation or the wholesale disappearance of palsa mires seems inevitable. Palsa mires are known to be biologically heterogeneous environments with a rich diversity of bird species, and they are listed as a priority habitat type by the European Union. However, their role as habitats for other organisms is still poorly understood. There is urgent need for research and monitoring to assess the ecological and biological consequences of the decline of palsa mires in Europe.

“…Holmes et al 1993in peatland, McFerran et al 1994 in heatland, Dennis et al 1997 in grassland, Gardner et al 1997 in moorland, Suominen et al 1999 in pine forest), the consequences of grazing by ungulates on the diversity of the arthropod fauna is rather unpredictable, depending on the habitat type and on the plant community (Gonza´lez-Megias et al 2004). For example, in a study conducted in Lapland, carabid richness was higher at medium reindeer Rangifer tarandus grazing pressure while carabid abundance was higher at high grazing pressure (Suominen et al 2003).…”

The role of moose Alces alces L. in boreal forest – the effect on ground beetles (Coleoptera, Carabidae) abundance and diversity

et al. 2006

The indirect effect of moose Alces alces browsing on ground beetle's abundance and diversity was investigated by pitfall trapping in a mixed coniferous forest in Vestfold County (59°19¢ N, 9°50¢ E, Norway), during the summer of 2002. Three areas with different browsing pressures, ranging from non-to medium-and heavily browsed were chosen and dry weight of bilberry Vaccinium myrtillus and humidity at ground level were measured in the three locations. As predicted, the gradient analyses showed that browsing by moose influenced the composition of carabid fauna, and that browsing intensity and humidity covaried with the most important gradient in carabid species composition found across the three locations. Species that live in light stands with rather dry soil, were more often captured in the browsed areas, whereas shade tolerant and hygrophilous species were more abundant in the non-browsed area. The carabid abundance increased significantly with increasing browsing pressure. According to our predictions, the diversity at trap level (a-diversity) was higher in the highly browsed area. Conversely, species turnover (b-diversity) decreased with browsing intensity. On the other hand, the rarefaction analysis showed that the regional species richness (c-diversity) was considerably higher in the medium browsed area than in the heavily browsed one, which is consistent with the intermediate disturbance hypothesis. This study indicates that moose, by reducing the bilberry that constitutes the field layer in summer, affect carabid species composition and might be capable to reshape the whole ecosystem in our study area by a cascade effect.
