Length-mass relationships of pond macroinvertebrates do not hold between Southern and Northern Europe.

The lack of reliable data on length-mass relationships, essential to obtain accurate biomass estimates, limits our ability to easily assess secondary production by aquatic invertebrates. In the absence of published equations from similar habitat conditions, authors often borrow equations developed in geographic regions with different climate conditions, which may bias biomass estimates. A literature overview of published size-mass relationships for Portugal and Sweden highlights the need for further data within these biogeographic regions.

Invasive infections impact gut microbiota in a definitive host in Europe.

Invasive parasites that expand their natural range can be a threat to wildlife biodiversity and may pose a health risk to non-adapted, naive host species. The invasive giant liver fluke, , native to North America, has extended its range in Europe and uses mainly red deer () as definitive hosts. The penetration of the intestinal barrier by the young flukes to reach the liver via the abdominal cavity as well as the release of fluke metabolism products and excreta with the bile and/or changes in the microbial community of the biliary system may enable the translocation of intestinal bacteria across the intestinal barrier and, in turn, could be associated with inflammation and changes in the intestinal bacterial community.

What makes a devoted local-food-buying club customer?

Local food-buying clubs (LFBCs) are special types of consumer-driven grassroots groups that are particularly well suited to enhancing the transition to a post-growth economy, given the finite growth potential of individual communities, the tendency of groups to distribute rather than accumulate capital, and the prospects of the movement for expansion. This paper analyses consumers of LFBCs and analyses how the different constructs proposed by the theory of planned behaviour are applicable according to engagement with LFBCs. A representative survey was run in May 2020 in Hungary.
