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

Oikos, Volume 2026, Issue 5, May 2026.
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.

Strategies for Designing Cryogenic Aqueous Zinc‐Ion Batteries: From Electrode Engineering to Electrolyte Optimization

ChemElectroChem, Volume 13, Issue 8, 15 April 2026.
This review provides a systematic overview of recent designing strategies in low‐temperature AZIBs, with a focus on the modification of cathodes, anodes, and electrolytes. Furthermore, this review examines the future challenges for low‐temperature AZIBs and outlines strategies that synergistically integrate electrode engineering with electrolyte ...

Evidence of negative density‐dependent dispersal in an invasive forest pest

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract Understanding the mountain pine beetle's dispersal patterns is critical for evaluating its threat to Canada's boreal forests. It is generally believed that higher beetle densities lead to increased long‐distance dispersal. One possible explanation is that beetle aggregation pheromones become repellent at high concentrations, causing beetles to

Aerial spraying of bacterial insecticides to control spruce budworm defoliation leads to reduced carbon losses

Ecosphere, 2020
Spruce budworm (SBW) outbreaks are a major natural disturbance in boreal forests of eastern North America. During large‐scale infestations, aerial spraying of bacterial insecticides is used to suppress local high‐density SBW populations.

Evaluating the efficacy of eBird data for modeling historical population trajectories of North American birds and for monitoring populations of boreal and Arctic breeding species

Avian Conservation and Ecology, 2020
Historic population trajectories for most North American bird species are largely unknown for years prior to circa 1970. Additionally, current estimates of population trajectories of boreal and Arctic breeding species are imprecise or biased because of ...
