The first comprehensive multilocus phylogeny of the lichenized genus Micarea (Ectolechiaceae, Ascomycota)

TAXON, Volume 75, Issue 1, Febuary 2026.
Abstract Micarea is a crustose cosmopolitan lichen genus that belongs to the euascomycete class Lecanoromycetes. Recent molecular phylogenies on the genus based on one to three loci have mostly focused on Micarea s.str., including the type species M. prasina, and suggested that Micarea s.l. is paraphyletic.

Private or Public? Farmer Preferences and Identities in Agri‐Environmental Contract Implementation

Journal of Agricultural Economics, Volume 77, Issue 1, Page 107-129, February 2026.
ABSTRACT This study investigates farmer preferences for publicly and privately financed agri‐environmental contracts. Using a labelled Discrete Choice Experiment with 366 German grassland farmers, we examine trade‐offs between payment schemes (public/private), payment criteria (practice‐based/result‐based), collaboration options, and advisory services.

Protected Areas and Agricultural Biodiversity Conservation—Do Parks Increase AES Adoption?

Journal of Agricultural Economics, Volume 77, Issue 1, Page 225-243, February 2026.
ABSTRACT Although both protected areas and agri‐environment schemes (AES) aim to conserve biodiversity, the interaction between the two policy instruments is unknown. We investigate the effects of listing a region as a protected area (a regional nature park) on the uptake of biodiversity conservation AES within the region. Using panel data of all Swiss

Reviewing seas of data: Integrating image‐based bio‐logging and artificial intelligence to enhance marine conservation

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 272-290, February 2026.
Abstract Conservation of marine ecosystems can be improved through a better understanding of ecosystem functioning, particularly the cryptic underwater behaviours and interactions of marine predators. Image‐based bio‐logging devices (including images, videos and active acoustic) are increasingly used to monitor wildlife movements, foraging behaviours ...
