Intercropping mitigates incidence of the oilseed rape insect pest complex

Pest Management Science, EarlyView.
Intercropping reduces the incidence of the oilseed rape insect pest complex with a significant impact of the direct visual and physical disruption provided by the companion plant. Abstract BACKGROUND Oilseed rape (OSR, Brassica napus) is a major crop requiring numerous phytosanitary treatments.

Accounting for animal movement during aerial imaging surveys

Remote Sensing in Ecology and Conservation, EarlyView.
Animals are not stationary during aerial surveys; if their movements are related to the movement of the aerial platform, then bias can be introduced into subsequent population count estimates. We sought to establish a framework for assessing the impacts of animal movement on count error and platform bias by comparing aggregated counts and relative ...

Tracking Wintertime Behaviour of Emperor Penguins Using High‐Resolution Synthetic Aperture Radar Imagery

Remote Sensing in Ecology and Conservation, EarlyView.
Using 25–30 cm Umbra synthetic aperture radar (SAR) imagery combined with ground validation of our observations, we introduce a method to track the phenology of emperor penguins during the Antarctic winter. We successfully identified events in the breeding cycle, which were previously impossible to observe during the complete darkness of Antarctic ...

Remote Sensing‐Based Identification of Habitat Loss for Herbivorous Waterbirds Driven by Wetland Inundation Alterations

Remote Sensing in Ecology and Conservation, EarlyView.
We present a deep learning framework integrating remote sensing and SHAP interpretation to map 22‐year habitat dynamics of herbivorous waterbirds in Dongting Lake. Results show nearly 50% habitat loss, driven primarily by hydrological recession timing rather than static inundation extent.

Overwintering of Usutu virus in mosquitoes, The Netherlands

Parasites & Vectors
AbstractAnalyses of mosquito-borne virus outbreaks have revealed the presence of similar virus strains over several years. However, it remains unclear how mosquito-borne viruses can persist over winter, when conditions are generally unfavorable for virus circulation. One potential route for virus persistence is via diapausing mosquitoes.

The oxygen and pressure physiology of upper elevational range limits in insects

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate warming is widely expected to cause montane insects to shift upslope, and there is good evidence that some populations are doing so. Nevertheless, patterns are mixed—with evidence supporting upslope, downslope or even no movement of both lower and upper range ...

Characterization of the imaginal reproductive diapause of Oebalus poecilus (Dallas) (Hemiptera: Pentatomidae)

Brazilian Journal of Biology
The state of development of the internal reproductive organs of male and female Oebalus poecilus (Dallas) as well as the body fat amount in the abdominal cavity during hibernation, of individuals sampled in bamboo litter in Eldorado do Sul (30º02'S and ...

Resilience in the heights: Elevational filtering preserves taxonomic and functional beta diversity over time against biotic homogenization

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Environmental heterogeneity generates taxonomic and functional beta diversity, but a key question regards whether heterogeneity can maintain functional diversity when global change causes range shifts, potentially causing biotic homogenization by favouring species ...

Density dependence and habitat selection affect overwintering abundance of monarch butterflies at regional and site scales in California

Conservation Science and Practice
The monarch butterfly (Danaus plexippus) is a species of iconic cultural interest. Thanks to annual overwintering monarch counts at hundreds of locations in coastal California, we are able to track fluctuations with high temporal and spatial resolution ...

Fungal Batrachochytrium dendrobatidis infections proliferate during amphibian terrestrial dormancy

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The spread and impact of wildlife pathogens is often seasonal, and identifying the season(s) of highest impact can be critical to biodiversity and public health management.
