Evolution of Repetitive Genomic Content and Gene Families Over Geo‐Climatic Gradients in Brassicaceae

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Along temperature gradients such as elevation and latitude, species typically occupy distinct ranges, and life at the extremes may come with adaptive and non‐adaptive genomic changes. In the Brassicaceae family, comparative genomics revealed that geo‐climatic factors strongly predict genome size and transposable element (TE) content, explaining up to ...

Structural and Functional Co‐Adaptation of Plants of the Genus Lysimachia L. (Primulaceae) and Pollinating Insects of the Genus Macropis Panzer (Hymenoptera, Melittidae)

Ecology and Evolution, Volume 15, Issue 12, December 2025.
The co‐adaptation of bees from the genus Macropis and Lysimachia plants has been studied in detail. Research shows that bees collect not just pure liquid oil from flower petals but tear off trichome heads filled with oil, transferring them to their nests.

Extreme drought and long‐term vegetation change: Seedling establishment as a bottleneck of grassland recovery

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Extreme events, such as droughts, may severely affect ecosystem structure and functions in the short term. While in a stable climate, ecosystems are expected to recover in the long term, in an era of accelerating climate change, it is a critical question whether ecosystems recover to their pre‐drought state and what limits recovery.

Seed mix performance and species network roles as a framework to select candidate key resources for pollinator habitat

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Current native bee declines have been attributed in part to loss of habitat and floral resources. Mitigation approaches include trying to establish or enhance bee habitat by planting wildflowers, which is often done by using seed mixes. Most assessments of plant performance in pollinator seed mixes are based on the abundance and diversity of ...
