• Alien tree clearing is predicted to increase mean streamflow by 15.1–29.5%. Clearing trees in riparian areas had a 1.7x greater impact than terrestrial areas. Greatest impacts were the mid low flows, and dry relative wet years. Caused decreasing transpiration increasing overland flow interflow. exotic from treeless ecosystems may improve water security. Ecological restoration efforts at scale...

Early-successional vegetation is often a major factor that limits recovery of tropical forest in abandoned pastures by outcompeting seedlings of forest trees. The goal of this study was to compare the effects of aboveand below-ground competition of pasture grasses and shrubs on the growth of tree seedlings in abandoned tropical pasture in Costa Rica. Seedlings of Calophyllum brasiliense were pl...

We present Guaranteed Search with Spanning Trees (GSST), an anytime algorithm for multi-robot search. The problem is as follows: clear the environment of any adversarial target using the fewest number of searchers. This problem is NP-hard on arbitrary graphs but can be solved in linear-time on trees. Our algorithm generates spanning trees of a graphical representation of the environment to guid...

Spatial heterogeneity in woody cover affects biodiversity and ecosystem function, and may be particularly influential in savanna ecosystems. Browsing and interactions with herbaceous plants can create and maintain heterogeneity in woody cover, but the relative importance of these drivers remains unclear, especially when considered across multiple edaphic contexts. In African savannas, abandoned...

We investigated the impact of pastoral management on birds in subtropical grassy eucalypt woodland in southeastern Queensland, Australia, where the patterns of land management have made it possible to disentangle the effects of livestock grazing from those of tree clearing. We recorded changes in bird species composition, density, and relative abundance across two woodland habitat types (ripari...

Abstract Background and Aims: Hop stunt viroid (HSVd, genus Hostuviroid, family Pospiviroidae) has a wide host range among trees and herbaceous plants. The objectives of this study were to compare biological and physical characteristics of three isolates of HSVd from mulberry, fig and citrus and search for other hosts of this viroid in Iran. Materials and Methods: Plant samples were col...

At the beginning of the 1900s, the Canberra plain was largely treeless. Graziers had carried out extensive clearing of the original trees since the 1820s leaving only scattered remnants and some plantings near homesteads. With the selection of Canberra as the site for the new capital of Australia, extensive tree plantings began in 1911. These trees have delivered a number of benefits, including...

Introduction. Queensland has accounted for more than 60% of the land clearing in Australia over the last 30 years and there is continuing evidence that the rate of land clearing in Queens-land is increasing (Queensland Department of Natural Resources 2000). State legislation (Vegetation Management Act 1999 and Vegetation Management Regulation 2000) and federal legislation (Environment Protectio...

Abstract Quantifying how well Nature-based Solutions can offset anthropogenic climate change impacts is important for adaptation planning, but has rarely been done. Here we show that a widely-applied Solution in South Africa – invasive alien tree clearing reduces the impact of on drought streamflow. Using multi-model joint-attribution and landscape-vegetation states during 2015–2017 Cape Town “...

solid waste municipal landfill can have significant health, economic and environmental effects. therefore, there is a need to comprehensive land evaluation for locating the best landfill place. the purpose of this paper is showcasing the process undertaken to locate the best landfill site for municipal solid waste of golpayegan township. at first, three alternatives were proposed after field su...
