Plant Growth and Arthropod Assemblage Metrics on Sapindus saponaria Fertilized With Dehydrated Municipal Sewage Sludge

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Under the conditions evaluated, dehydrated municipal sewage sludge increased branches per plant and ground cover in Sapindus saponaria and increased cumulative arthropod observations and species richness in selected groups. Exploratory multivariate patterns did not demonstrate direct causal plant–arthropod relationships.

Interactions of land use and climate change disproportionately impact Lepidoptera of the five major insect orders

open access: yesInsect Conservation and Diversity, EarlyView.
Land use and climate change are two major environmental pressures that interact to impact insect biodiversity. We compared the impacts of land use alone and of the interaction between land use and climate change on the five major insect orders. Most impacted were the Lepidoptera, showing 91% lower total abundance in sites of high‐intensity agriculture ...

Woody vegetation can promote pollinator biodiversity in semi‐natural grasslands

open access: yesInsect Conservation and Diversity, EarlyView.
Up to 24% shrub cover in Swedish semi‐natural grasslands is positively related to butterfly diversity, while butterfly diversity increases up to 18% deciduous hardwood tree cover. Initially positive effects of tree and shrub cover on butterfly abundance were detected on those butterflies that use trees and shrubs as host plants.

Children Show Stronger Learning‐Dependent Explicit Knowledge Than Adults After Offline Wake or Sleep Intervals

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Previous research has extensively investigated the impact of post‐training sleep and wakefulness on procedural memory consolidation across development. However, results regarding how offline processes specifically affect the explicit and implicit components of newly acquired procedural skills in children and adults remain controversial.

No need to seed: restoring species‐rich grassland on former arable fields by natural regeneration

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Over the last century, agricultural intensification has caused substantial losses of semi‐natural species‐rich grasslands. One means of restoring grassland habitat is to abandon farmed land, followed by mowing and/or grazing of the established vegetation to facilitate meadow diversification. Objectives This study investigated post‐
