Carbon storage of headwater riparian zones in an agricultural landscape

Carbon Balance and Management, 2012
Background In agricultural regions, streamside forests have been reduced in age and extent, or removed entirely to maximize arable cropland. Restoring and reforesting such riparian zones to mature forest, particularly along headwater streams (which ...

Edges as ecological filters: Asymmetrical orientation‐specific arthropod activity across forest boundaries

Insect Science, EarlyView.
Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.

Black alder may enhance riparian buffer mitigation of pine-plantation effects on macroinvertebrate food webs in headwater streams

Ecological Indicators
Over the past century, drylands have undergone significant landscape transformations. Abandonment of traditional crops and pastures led to development of extensive afforestation programs with conifers, which often lacked an ecologically sound orientation,

The impact of land use landscape pattern on river hydrochemistry at multi-scale in an inland river basin, China

Ecological Indicators, 2022
The impact of the land use landscape pattern on river hydrochemistry has significant scale effects. It is the premise and foundation of landscape optimization and the conservation of water resources to accurately identify the core scale of the landscape ...

Extinction Debt Paid Off: The Demise of the European Polecat (Mustela putorius) in NE Iberia

Integrative Zoology, EarlyView.
We studied a vanishing polecat population for a decade, until its ultimate demise, using camera trap and roadkill data, landscape descriptors and dietary and toxicological analyses.Polecat favoured farmland and avoided forests and water bodies occupied by the invasive American mink.

Capacity of riparian buffer zones to reduce sediment concentrations in discharge from peatlands drained for forestry

Silva Fennica, 2005
In 1995–2001, the efficiency of riparian buffer zone areas to reduce the concentrations of suspended solids in discharge from peatlands drained for forestry purposes was studied at 7 locations in south-central Finland.

Spatial Patterns of Avian Stable Isotopes Reveal Ecological Impacts of Climate and Land‐Use Change

Integrative Zoology, EarlyView.
Increased feather δ15N values with pasture coverage reveal an elevated baseline δ15N in grazing landscapes, while broader isotopic niches in farmland habitats reflect agricultural expansion's significant influence on resource use patterns of the avian community.

Life Under the Snow: Camera Trap Videos Capture Year‐Round Lemming Activity and Behavior

Integrative Zoology, EarlyView.
We developed an automated camera system capable of recording year‐round videos of lemmings beneath the snow in the High Arctic. We demonstrate the potential of this system to document lemming activity and behaviors. Our results show that it effectively monitors lemming relative abundance with temporal precision unmatched by other methods.

Concentrated flow paths in riparian buffer zones of southern Illinois

Agroforestry Systems, 2011
Riparian buffers in agricultural landscapes should be designed to trap pollutants in overland flow by slowing, filtering, and infiltrating surface runoff entering the buffer via sheet flow. However, observational evidence suggests that concentrated flow is prevalent from agricultural fields. Over time sediment can accumulate in riparian buffers forming

Ground‐penetrating radar amplitudes to roots: A numerical modelling framework for mapping coarse root system architecture

Methods in Ecology and Evolution, EarlyView.
Abstract Observations of three‐dimensional (3D) coarse root system architecture remain limited because most measurement approaches require excavation. Here, we combined dense single‐ and multi‐channel 500 MHz ground‐penetrating radar (GPR) surveys with a flow‐guided connectivity framework to non‐destructively characterise the coarse root architecture ...
