The nitrogen dilemma: Toward a novel fertilization management framework for reconciling productivity and diversity in grasslands

open access: yesGrassland Research, EarlyView.
Nitrogen fertilization raises grassland productivity but steadily undermines plant diversity. Instead of applying the same rate everywhere every year, the PRISM framework is designed to rotate high‐ and low‐nitrogen paddocks across the farm over time. This spatiotemporal cycling aims to maintain farm‐scale productivity while creating periodic windows ...

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Drought intensifies dominant competitor avoidance and risk‐dependent habitat selection in a large carnivore guild

open access: yesOikos, EarlyView.
Intraguild competition is a key force structuring predator communities, with dominant species impacting subordinate species' space use and access to resources. Climate change may intensify or reshape these processes, yet how climate conditions interact with dominance to influence predator space use and resource selection remains poorly understood.

From mainland to islands: the evolution of resistance and tolerance to herbivory in long‐lived oaks

open access: yesOikos, EarlyView.
Island biogeography theory predicts that island plants should exhibit reduced defences compared with their mainland relatives due to relaxed herbivory pressure. However, growing empirical evidence challenges this prediction, revealing substantial variation among systems, plant lineages and defence types.

Potential fecundity, larval development, and survival of two invasive species of Arhopalus (Coleoptera: Cerambycidae) coexisting in southern South America

open access: yesCaldasia, 2019
Biological invasions are one of the main threats to forest health. Although Arhopalus rusticus and Arhopalus syriacus (Cerambycidae) are alien species in South America, the ecology of these invasive species is not well studied.
