TL;DR: It is concluded that the ground beetle assemblages of the studied sites respond in a similar way to the same underlying environmental factors, which allows the precise definition of functional groups, which can be used to characterize functional diversity and its relationships with changes in land management.

TL;DR: A CO1 data set of aquatic predaceous diving beetles of the tribe Agabini is presented and it is shown that even if samples are collected to maximize the geographical coverage, up to 70 individuals are required to sample 95% of intraspecific variation, showing that the geographical scale of sampling has a critical impact on the global application of DNA barcoding.

TL;DR: In this article, the authors classify ground beetle species, collected from farmland habitats in Scotland, into distinct groups based on their ecological traits and investigate the influence of agricultural land use and management intensity on these ecological groups.

TL;DR: It is proposed that effects of habitat, in this case possibly mediated by different long term persistence of running and standing water bodies, impose constraints at the population or local level which, if effective over larger temporal and spatial scales, determine global patterns of species richness.

TL;DR: Water beetles were recorded from 157 sites around the Wash, England, in 1986 as discussed by the authors, most of which were ditches in arable land and the habitats of these assemblages were characterized by measurement of a range of physical and chemical factors.
