Mixed plant and arthropod biodiversity responses to solar park establishment on former agricultural lands

Journal of Applied Ecology, EarlyView.
Our results suggest that while biodiversity can increase in solar parks post‐conversion compared to previous land use, not all taxonomic groups benefit from the land use change. Potential benefits for certain groups (particularly for butterflies and soil‐emergent arthropods) are likely lost due to disturbance during land conversion and solar panel ...

Landscape and crop diversity contributes to greater yield stability

Journal of Applied Ecology, EarlyView.
These findings underscore the importance of promoting crop diversity and maintaining heterogeneous agricultural landscapes, particularly in pollinator‐dependent crops. Promoting diverse agricultural landscapes with balanced heterogeneity can enhance the resilience of agricultural systems to climate change and contribute to long‐term food security ...

Melittopalynology and Trophic niche analysis of Apis cerana and Apis mellifera in Yunnan Province of Southwest China

Sociobiology, 2013
The present study reports results of qualitative melittopalynological analyses of 34 honey samples of Apis cerana and Apis mellifera between 2011 and 2012 in Mengzi (China Yunnan) and the trophic niche analysis of two bee species on pollen food resources.

A pan‐European citizen science study shows population size, climate and land use are related to biased morph ratios in the heterostylous plant Primula veris

Journal of Ecology, EarlyView.
A large‐scale citizen science study involving thousands of cowslip (Primula veris) observations from all over Europe revealed an unexpected prevalence of S‐morphs over L‐morphs, which was influenced by climatic as well as land use factors. Furthermore, general morph ratios were often unbalanced with the strongest shifts occurring in smaller populations.

Experimental resource supplementation shifts ant‐mediated defence on silver cholla

Journal of Ecology, EarlyView.
The partitioning of EFN resources between ant species influences defence and subsequent fitness effects on silver cholla. Abstract Extrafloral nectaries (EFN) often mediate facultative mutualisms between plants and ants. Ants obtain a nutrient‐rich food source from plants in exchange for defending the plant from herbivores.

Fire‐induced disturbances in Malpighiaceae sequential flowering: Implications for pollination services and plant reproductive success

Plant Species Biology, EarlyView.
Our study demonstrates that fire has a strong influence on flowering phenology and reproductive dynamics in Malpighiaceae species from the Brazilian Cerrado. Specifically, fire triggered an earlier onset of flowering and promoted a more synchronous and widespread blooming, resulting in a temporary surge in floral resource availability. This increase in
