Substrate size modifies stream grazer–biofilm interactions in the presence of invertivorous fish
Ecology, Volume 103, Issue 12, December 2022., 2022 Abstract When herbivore abundance is controlled by predators there may be an indirect positive effect on primary producers due to reduced grazing pressure, but the potential of predation refuges to modify such trophic cascades has rarely been studied.

The effects of management practices on grassland birds — An introduction to North American grasslands and the practices used to manage grasslands and grassland birds [PDF]
Professional Paper, 2019 Summary The Great Plains of North America is defined as the land mass that encompasses the entire central portion of the North American continent that, at the time of European settlement, was an unbroken expanse of primarily herbaceous vegetation. The Great Plains extend from central Saskatchewan and Alberta to central Mexico and from Indiana to the ...

Economics and human dimension of active managment of forest grassland ecotone in south-central USA under changing climate [PDF]
arXiv, 2023 The south central ecoregion was a mosiac ecoregion of forest and grassland continnum which is transiting towards closed canopy forests and losing ecosystem benefits. We studied role of active management, its economic benefit, and landonwers atttitdue and behavior towards restoring ecosystem services in this region.

Model-based scenario analysis for effective site-specific weed control on grassland sites [PDF]
, 2021 The site-specific management of weeds in grassland is often challenging because different weed control strategies have different trade-offs regarding the required resources and treatment efficiency. So, the question arises whether a wide tractor-based system with section control or a small agricultural robot has a higher weed control performance for a ...

Ecology, Volume 103, Issue 12, December 2022., 2022 Abstract The outcomes of species interactions can vary greatly in time and space with the outcomes of some interactions determined by priority effects. On coral reefs, benthic algae rapidly colonize disturbed substrate. In the absence of top‐down control from herbivorous fishes, these algae can inhibit the recruitment of reef‐building corals, leading ...

Energy-Sensitive Trajectory Design and Restoration Areas Allocation for UAV-Enabled Grassland Restoration [PDF]
arXiv, 2022 Grassland restoration is a critical means to safeguard grassland ecological degradation. To alleviate the extensive human labors and boost the restoration efficiency, UAV is promising for its fully automatic capability yet still waits to be exploited. This paper progresses this emerging technology by explicitly considering the realistic constraints of ...

Root hemiparasitic plants are associated with more even communities across North America
Ecology, Volume 103, Issue 12, December 2022., 2022 Abstract Root hemiparasitic plants both compete with and extract resources from host plants. By reducing the abundance of dominant plants and releasing subordinates from competitive exclusion, they can have an outsized impact on plant communities. Most research on the ecological role of hemiparasites is manipulative and focuses on a small number of ...

Bridging Social Innovation with Forest and Landscape Restoration
Environmental Policy and Governance, Volume 32, Issue 6, Page 520-531, December 2022., 2022 Abstract Mitigating climate change, preventing mass species extinctions, improving rural livelihoods, and disaster risk reduction are among today's most urgent challenges. To meet these challenges, a large number of social actors need to agree to engage and act collectively on Forest and Landscape Restoration (FLR), ensuring its dual goal of restoring ...

Recurrence Analysis of Vegetation Time Series and Phase Transitions in Mediterranean Rangelands [PDF]
Landscape Ecology 33 (2018) 1617-1631, 2017 Mediterranean rangelands should be conceived as socio-ecological landscapes (SEL) because of the close interaction and coevolution between socio-economic and natural systems. A significant threat to these Mediterranean rangelands is related to uncontrolled fires that can cause potential damages due to the reduction or even the loss of ecosystems.

Biogeomorphic recovery of a river reach affected by mining
Earth Surface Processes and Landforms, Volume 47, Issue 15, Page 3497-3514, December 2022., 2022 The Grogwynion reach of the River Ystwyth,Wales, affected by mining in the 19th and 20th centuries, has shown a progressive reversion to a sinuous single‐channel planform since 2001 from an active braided pattern. A critical factor has been a change in the extent and type of riparian vegetation occurring within the active zone of the river due to the ...
