Agrestal Environments and Maternal Genetic Effects Weaken the Ecological Barriers for Crop to Wild Introgression in Sunflower

Ecology and Evolution, Volume 16, Issue 2, February 2026.
We highlight how agrestal environments and maternal effects may facilitate the adaptation of crop‐wild hybrid sunflower to agroecosystems. We present two consecutive years of data on diverse wild and reciprocal crop‐wild hybrid sunflower populations planted in three contrasting, ruderal or agrestal, environments. We found that (i) agrestal environments

Of walls and floors: how physical structures affect mating song detection in stridulating orthopterans

Ecological Entomology, Volume 51, Issue 1, Page 141-152, February 2026.
Schematic representation of the experimental settings for one field type. Each setting was assigned one of the three treatments (i.e., walls, floors, or control). Each treatment contained an AudioMoth™ (circle), either positioned close to the ground (5 cm) or elevated (60 cm), acting as a receiver organism. Abstract Sensory ecology theory proposes that

Ecological Effects of Solanum rostratum Invasion on the Diversity and Functional Traits of Native Plant Communities

Ecology and Evolution, Volume 16, Issue 1, January 2026.
The invasion of Solanum rostratum exerts stage‐dependent effects on native plant communities. The study found that at low invasion levels, it temporarily enhances native plant diversity and community stability through resource complementarity; whereas at high invasion levels, it shifts to strong competitive inhibition, leading to a sharp decline in ...

Hydrochorous Dispersal of Diaspores in a Reconnected Floodplain: Distribution Patterns and Potential for the Development of Floodplain Habitats

Applied Vegetation Science, Volume 29, Issue 1, January/March 2026.
Dike relocation reconnected a section of the Elbe River to its floodplain, thereby restoring a more natural flooding regime, and hydrochorous dispersal of diaspores. Low areas received the most abundant and diverse diaspore deposition, which was dominated by herbaceous species characteristic of open floodplain habitats.

Photoperiod–Temperature Interactions in a Changing Climate: A Review of Plant Phenological Responses

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Climate change is reshaping plant phenology and species distributions, especially in temperate and boreal ecosystems, where advances in spring events have already extended the growing season. While temperature has been the primary focus of many studies, the role of photoperiod—a stable, latitude‐dependent cue—remains underexplored.
