Aim Species on islands are at high risk of extinction due to environmental changes, including global warming, land-use alterations and invasions. At local scales, extinctions can be offset by strategies promoting in situ persistence. We explored how persistence-related traits plants—that is, linked belowground resource conservation, growth, size longevity—on edaphic respond variation insularity...
Abstract Purpose To assess 1) the cumulative greenhouse gas emissions –GHG- and global warming potential (methane – CH 4 - nitrous oxide) from rice fields in growing fallow seasons, 2) environmental agronomic drivers of emissions, their relative capacity to explain variation. Methods A two-year multisite field experiment covering variability a area NE Iberian Peninsula was conducted with monthl...
during an investigation on edaphic mite fauna of wheat fields in abarkooh (yazd province) and citrus orchards in jahrom (fars province), some specimens belonging to the family oplitidae were collected and identified as oplitis paradoxa (canestrini & berlese). this is the first report of this species from iran.
Improved agricultural, forestry, and land management practices could be used to increase soil carbon and thereby significantly reduce atmospheric CO2 concentration. Understanding biological and edaphic processes that increase and retain soil carbon can lead to specific manipulations for enhancement of soil C sequestration. These manipulations, however, will only be suitable for adoption if they...
nce County, Wisconsin was the first to receive systematic study (Giese et al., 1964; Westing, 1966; Millers et al., Sugar maple (Acer saccharum Marsh.) decline has been a problem 1989). Since then, well-documented sugar maple deon the Allegheny Plateau for the last two decades. Previous work found that sugar maple is predisposed to decline by poor nutrition clines have occurred in Massachusetts...
Tropical forests play a vital role in preserving world biodiversity and supporting ecological services. Moreover, the spatial distribution of species diversity its causes are one core issues community ecology. Therefore, aim this study was to explore horizontal characteristics shrub tropical region Hainan reveal relationship between environmental factors under anthropogenic disturbances. Based ...
The literature on wind damage in New Zealand forests is reviewed to investigate how abiotic and biotic factors influence damage severity, damage type, and forest recovery. Winds that damage forests tend to result from extra-tropical depressions or from topographically enhanced westerly air flows. Severe wind damage can occur when wind speeds exceed c. 110 km/hr, although investigating the relat...
