Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

Journal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

The power of choice: how early performance of tree species may shape direct seeding for tropical forest restoration

Restoration Ecology, EarlyView.
Abstract Introduction The success of direct seeding depends on appropriate species selection. Understanding the geographic and taxonomic distribution of species used, along with their performance profiles, can inform more effective restoration outcomes.

Tropical savanna restoration: topsoil removal and direct‐seeding promote a biodiverse and invasion‐resistant community

Restoration Ecology, EarlyView.
Abstract Introduction Open ecosystems, such as native grasslands and savannas, cover vast tropical areas and sustain multiple ecosystem services. However, they face intense degradation due to conversion into pastures with exotic grasses that invade natural ecosystems.

Effects of LED Light Exposure on Lutein and Bioactive Compounds in Nasturtium Flowers (Tropaeolum majus L.)

Future Postharvest and Food, Volume 3, Issue 3, Page 350-360, September 2026.
Red LED supplementation during cultivation modulated the accumulation of bioactive compounds in Tropaeolum majus flowers. Moderate exposure (3–5 h) enhanced antioxidant capacity and increased carotenoids, phenolics, and anthocyanins depending on petal color, highlighting a simple strategy to improve the functional value of edible flowers. ABSTRACT This

The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

Oikos, Volume 2026, Issue 9, September 2026.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.
