Identifying traits that affect the reproductive success of individuals is fundamental for our understanding of evolutionary processes.
The Dublin SURGE (Soil Urban Geochemistry) Project is Dublin’s first baseline survey of heavy metals and persistent organic pollutants in topsoils and is part of a Europe-wide initiative to map urban geochemical baselines in ten cities.
Over the past decades, the vast limestone mountain areas in southwestern China have suffered greatly from karst rocky desertification (KRD), which is a unique type of desertification caused by irrational land-use practices and has drawn increasing attention of international academic community.
The majority of residents in the rural Middle Hills of Nepal use fuelwood from public and private sources as their primary energy source.

Natural wetland ecosystem plays an important role in global climate change due to its large amounts of stored carbon and nitrogen. The Sanjiang Plain, Northeast China, encompasses large area of natural freshwater marshy wetlands.
Many arid and semi‐arid landscapes around the world are affected by a shift from grassland to shrubland vegetation, presumably induced by climate warming, increasing atmospheric CO₂concentrations, and/or changing land use.
In this study, flow experiments were conducted, and flow parameters were evaluated to determine the suitable furrow length in furrow irrigation under Bafra plain conditions. By using 1.5, 2.0 and 2.5 L/s inflow rate, flow experiments were conducted and infiltration situation were determined.
