Influence of number of pollinations and pollen load size on maternal fitness costs in Collinsia heterophylla: implications for existence of a sexual conflict over timing of stigma receptivity
Costs related to pollen competition have rarely been considered, but are expected in the case of sexual conflict where male and female sexual functions have opposing evolutionary interests. InExpand
Sexually antagonistic evolution caused by male–male competition in the pistil
It was found that high siring success of early arriving pollen competing with later‐arriving pollen was associated with high female fitness costs, consistent with an interlocus sexual conflict. Expand
Effects of soil resources on expression of a sexual conflict over timing of stigma receptivity in a mixed-mating plant
Even though soil resource environment had a low impact on the sexual conflict traits and related costs in C. heterophylla, it generated variability in pollen donor-influence on this trait and in recipient sorting among donors, suggesting that both sexual conflict and sexual selection is affected by environmental factors not only in animals but also in plants.

The effects of pH and disturbance on the bryophyte flora in calcareous sandy grasslands
It was found that increased pH due to soil perturbation resulted in increased species richness, however, in naturally disturbed areas, pH seemed to have a lower effect, and instead, the location of the site and possibly the site history had a larger influence on species richness. Expand
Tillage practices and their impact on soil organic carbon and the microbial community

Soil microorganisms are important for climate regulation as well as for plant nutrition. In agricultural soils the microorganisms are affected by management choices, like which type of tillage thatExpand
Reduced tillage stimulated symbiotic fungi and microbial saprotrophs, but did not lead to a shift in the saprotrophic microorganism community structure
The need for sustainable agricultural systems, which for example enhance soil organic carbon (SOC) content, has increased the interest for management with reduced tillage. In this study we used aExpand
Late Blight Resistance Screening of Major Wild Swedish Solanum Species: S. dulcamara, S. nigrum, and S. physalifolium.
In Sweden S. physalifolium is susceptible and could be a player in epidemiology, and a limited role of S. dulcamara leaves in the epidemiology of late blight was suggested, since no major symptoms have been found in the field. Expand
Biochemical signatures reveal positive effects of conservation tillage on arbuscular mycorrhizal fungi but not on saprotrophic fungi and bacteria
It is suggested that reducing or omitting plowing influence soil microbes, but does not necessarily result in more SOC. Expand

Conventional agricultural practices can lead to soil erosion and a reduction in soil organic carbon (SOC) content. It has been suggested that less intensive agricultural practices, such asExpand
Topsoil removal enhances plant target species occurrence in sandy calcareous grassland
Abstract Species-rich sandy calcareous grasslands are threatened by land use change, eutrophication and acidification. Disturbance is vital for the persistence of characteristic sandy calcareousExpand
