Relationship between food quality and body size of common vole in different habitats

open access: yesPest Management Science, EarlyView.
The body size of the common vole in crop fields (alfalfa, rape, cereals) is larger than in less‐cultivated habitats (forests, clearings, set‐aside) and is not related to food quality. Abstract BACKGROUND There is a close relationship between habitat, food and demographic parameters of common vole populations.

First record of Hypsocephalus dahli in Switzerland with a review of its distribution, ecology and taxonomy (Araneae, Linyphiidae) [PDF]

open access: yes, 2010
The spider species Hypsocephalus dahli (Lessert, 1909) is recorded for the first time in Switzerland from museum material collected in 1974. The information given in the literature and unpublished data on this rare species are summarised including an ...

Quantifying aboveground herbaceous biomass in grassy ecosystems: a comparison of field and high‐resolution UAV‐LiDAR approaches

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The abundance of herbaceous vegetation in grassy ecosystems—which cover >25% of the world's land surface—is highly variable and impacts key ecological processes including carbon sequestration and support for grazing wildlife and livestock. Here, we present a method for using high‐resolution, UAV‐borne Light Detection and Ranging (LiDAR) to estimate ...

Surface roughness measurements using UAV LiDAR and analysis of uncertainty factors

open access: yesRiver, EarlyView.
Abstract Surface root mean square height (SRMSH) is a key parameter characterizing surface roughness; it reflects soil hydrological properties and influences related physical processes. LiDAR offers an effective means for measuring SRMSH over large areas, yet the method involves several uncertainty factors that require further investigation.

Estimating Rain‐Specific Attenuation at Extremely High Frequencies From Disdrometer Measurements at Various Climate Zones in the US

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT The raindrop size distribution (DSD) plays an essential role in understanding rain attenuation effects at extremely high frequencies (EHFs). Over 1 year of DSD measurements was taken at different Köppen–Geiger climate classifications within the United States. Optical disdrometers from Thies Clima were used to measure both the size and velocity

Moderate grazing drives contrasting microbial network reorganization and functional shifts in desert and meadow steppes of Inner Mongolia

open access: yesGlobal Ecology and Conservation
Grazing strongly influences soil microbial communities and their roles in ecosystem functioning. However, it remains unclear how moderate grazing mediates microbial network organization and functional pathways under contrasting environmental contexts ...

Forgoing Nuclear: Nuclear Power Plant Closures and Carbon Emissions in the United States

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT This paper examines the effect of nuclear power plant decommissioning on electricity generation and carbon emissions in the United States. Using data on nuclear reactor closures in the United States between 1993 and 2022 and data on state‐level carbon emissions and electricity generation from the Energy Information Administration (EIA), this ...
