“Tremble, pests”: Insect natural enemy‐induced changes in pests before attack and their implications for biological control

open access: yesNew Plant Protection, EarlyView.
Abstract Insect natural enemies, encompassing predators and parasitoids, serve as vital regulators of pest populations and architects of ecosystem balance. Most studies on natural enemies have focused on understanding the mechanisms by which these insects eliminate pests after an attack.

Meteorological versus spatial drivers of the spatial synchrony of forest insect pest outbreaks in North America

open access: yesOikos, EarlyView.
Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.

Species identity and spatial scale drive context‑dependent tree diversity effects in a Finnish forest experiment

open access: yesOikos, EarlyView.
Tree species diversity is known to affect tree growth and leaf traits, which in turn can influence various ecosystem processes. However, the reported direction of these tree diversity effects is inconsistent, indicating that their outcomes depend strongly on ecological context.

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

open access: yesOikos, EarlyView.
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.

Transfer and biological effects of cadmium along a tomato – thrip – predatory bug food chain

open access: yesEcotoxicology and Environmental Safety
The heavy metal, cadmium (Cd) is an increasingly serious issue in agricultural ecosystems, mediating bottom-up effects on plants, herbivores and natural enemies. We measured how Cd modifies interactions between tomato Solanum lycopersicum, western flower

Cotton facilitates long‐distance seed dispersal by functioning as nest material for birds

open access: yesOikos, EarlyView.
Cotton (Cossypium) fibres, which grow naturally in bolls around the seeds of cotton plants, have been used for centuries to produce fabric. The presumed natural function of cotton is that these lightweight and fluffy fibres may support wind dispersal of the seeds inside.

Navigating the Rapids: How Non‐Governmental Organization Managers Develop Strategic Adaptation to Repressive Political Environments

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT This article explores the management adaptation strategies non‐governmental organizations (NGOs) managers employ in order to operate in repressive political environments. It answers the question: how do NGO managers initiate, manage and sustain internal change when the political/regulatory environment changes?
