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

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

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 ...

Chlorophyll Levels and Leaf Chlorplast Ultrastructure as Ecotypic Characters in Xanthium Strumarium L. [PDF]
The major objective of the work was to clarify some of the adaptive mechanisms that a common widespread species would show as a possible requirement for survival in its natural habitats.

Utilisation of Google Earth Engine to analyse Normalised Difference Drought Index trends in Narok (Kenya) across six timeframes. Trends revealed increased severe and moderate drought conditions and decreased drought conditions. Temporal increase has been on the rise from 2015, with extreme events most witnessed in 2020.

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.

Why is biocontrol of common ragweed (Ambrosia artemisiifolia), the most allergenic weed in Eastern Europe, still only a hope? [PDF]
This chapter presents the story of a long and as yet unsuccessful struggle to find suitable fungal and/or insect biocontrol agents for ragweed, a plant that became a widespread allergenic weed in Eastern Europe.

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