Stream Invertebrate Responses to Fine Sediment Depend on the Organic and Inorganic Components
Freshwater Biology, Volume 70, Issue 3, March 2025.ABSTRACT Excess fine sediment ( < 2 mm) is a pervasive stressor of aquatic systems at a global scale. To date, most research quantifying ecological response to deposited fine sediment has been conducted without distinguishing between the organic and inorganic components of fine sediment, leaving mechanistic understanding of how fine sediment affects ...

Nordic Journal of Botany, Volume 2025, Issue 3, March 2025.Many European terrestrial orchids are in decline. To curb this negative trend and preserve remaining populations, more ecological knowledge is needed. Surprisingly little is known yet about the identity and efficiency of pollinators of lesser twayblade Neottia cordata, a small terrestrial orchid species associated with pine trees through joint ...

Increasing variability in resource supply over time disrupts plant–pollinator interactions
Ecological Monographs, Volume 95, Issue 1, February 2025.Abstract Insect–plant interactions are key determinants of plant and insect fitness, providing important ecosystem services around the world—including the Arctic region. Recently, it has been suggested that climate warming causes rifts between flower and pollinator phenology.

River Research and Applications, Volume 41, Issue 1, Page 10-22, January 2025.Abstract Physical habitat modification is one of the main pressures affecting river environments, impacting their ecosystem health and compromising their ability to adapt to the effects of climate change. Addressing the impacts of physical modification through reinvigorating natural processes has become a globally established river restoration ...

River Research and Applications, Volume 41, Issue 1, Page 37-55, January 2025.ABSTRACT Stream restoration is a proposed climate adaptation tool; however, outcomes of floodplain restoration on stream temperature have been debated. Despite a growing number of studies that investigated water temperature in restored streams, few have quantified temperature variations in new habitat types created by restored hydrogeomorphic processes

Plant Species Biology, Volume 40, Issue 1, Page 70-85, January 2025.Eurya japonica and Eurya emarginata exhibited Diptera‐dominated pollination systems. The composition of flower visitors on the two Eurya species was not explained by their floral traits. These findings indicate that the floral traits are not specifically adapted to their local pollinators.
