Agricultural intensification, sustainable farming and the fate of arable bryophytes in Switzerland
- 2021

Ingår i: The Changing Status of Arable Habitats in Europe. - Cham, Switzerland : Springer. - 9783030598754 - 9783030598747 ; , s. 139-156

Bokkapitel (refereegranskat)abstract
- Land-use changes including agricultural intensification are major drivers of biodiversity loss. As other countries, Switzerland introduced agri-environment schemes (AES) to counteract declining agro-biodiversity. Among numerous bryophytes of the agricultural landscape, arable bryophytes have adapted to recurrent tillage. They are short-lived above-ground, while their diaspores may build up a persistent diaspore bank in the soil. We monitored the field hornwort and the Carolina hornwort, characteristic species of the Central European arable bryophyte flora over a period of almost three decades, and studied effects of Biodiversity Promoting Areas (BPAS), a key element of Swiss AES, on arable bryophyte diversity. Hornwort occurrences strongly declined, and stubble-fields left unprocessed until late autumn, the favourite habitat of arable specialist bryophytes, nearly disappeared from 1991 to 2018. The loss of suitable habitats follows from decreased cereal cultivation and direct post-harvest management. Different BPA-fallows, designed to promote birds, flowering plants, or ecosystem services, harboured arable bryophyte specialists, but their richness decreased with fallow age. Diaspore banks contained arable bryophyte specialists not occurring above-ground and may serve as a reservoir during unsuitable cultivation. Targeted modifications of current AES, aiming to maintain habitats favourable for arable bryophytes, are necessary to safeguard the typical arable bryophytes in the Swiss arable landscape.

Agricultural management, bedrock, and vulnerability of sexual reproduction to climate change affect the occurrence of a European near-endemic moss
- 2023

Ingår i: Bryophyte Diversity and Evolution.

Tidskriftsartikel (refereegranskat)abstract
- We investigated whether the European near-endemic moss Drepanocladus lycopodioides has declined in its core distribution area in the southern Baltic Sea region and explored potential explanations for this. First, we re-visited sites with documented records from 1854 to 1957 in the Stockholm archipelago and nearby mainland in southern Sweden. Second, we compared the numbers and distributions of Swedish occurrences, their habitats, and substrates up to 1950 (289 herbarium records), and from 1951 onwards (347) using different map layers. Third, we explored whether inter-annual variation in reproductive performance was related to moisture conditions at five sites on an island in the Stockholm archipelago during nine years. We estimated moisture conditions based on precipitation data and dry days during the time when fertilization occurs in the year prior to sporophyte maturation. Drepanocladus lycopodioides has strongly decreased in intensively managed agricultural landscapes but remains frequent in natural or semi-natural habitats on limestone. Sporophyte development varied between years and depended on the weather condition during the fertilization period. Climate forecasts for the study area predict longer dry spells during late spring to late summer, which coincides with the timing of sexual branch initiation and fertilization in the species. We expect that sporophyte production will likely decrease in the future, which will affect the species’ abilities to re-colonize spots where it vanishes during years with poor growth conditions.
