Human disturbances affect the topology of food webs

Ecology Letters, Volume 25, Issue 11, Page 2476-2488, November 2022., 2022
We predict that food webs with scale‐free degree distributions should be favourably selected by random disturbances (in regions less disturbed by human pressure) while food webs with random degree distributions would be associated with targeted disturbances (in areas with more human pressure).

Spatial dependence in the technical efficiency of local banks

Papers in Regional Science, Volume 101, Issue 3, Page 685-716, June 2022., 2022
Abstract Cooperative banks primarily compete with one another because they target niche markets that large banks typically ignore. The current study shows that in this competitive environment, the connection between financial intermediaries affects the operational efficiency of small banks. The findings indicate that the capitalization, diversification

Defining practical and robust study designs for interventions targeted at terrestrial mammalian predators

Conservation Biology, Volume 36, Issue 2, April 2022., 2022
Abstract Conflicts between humans and mammalian predators are globally widespread and increasing, creating a long‐lasting challenge for conservation and local livelihoods. Protection interventions, which are essential to conflict mitigation, should be based on solid evidence of effectiveness produced by robust study designs.

Trust your guts? The effect of gut section on diet composition and impact of Mus musculus on islands using metabarcoding

Ecology and Evolution, Volume 12, Issue 3, March 2022., 2022
In this article, we assessed the differences in diet estimates and potential ecological and economic impact measurements according to the section of the gastrointestinal tract (stomach, small and large intestine) analysed. We aimed to test which section(s) provided a better diet representation and putative impact of a common inland invader.

A critical analysis of the potential for EU Common Agricultural Policy measures to support wild pollinators on farmland

Journal of Applied Ecology, Volume 57, Issue 4, Page 681-694, April 2020., 2020
To conserve pollinators and help protect pollination services, our expert elicitation highlights the need to create a variety of interconnected, well‐managed habitats that complement each other in the resources they offer. To achieve this the Common Agricultural Policy post‐2020 should take a holistic view to implementation that integrates the ...
