the breakdown and decomposition of sweet chestnut (castanea sativa mill.) and beech (fagus sylvatica l.) leaf litter in two deciduous woodland soils : i. breakdown, leaching and decomposition.	weight losses from sweet chestnut and beech leaves, attributable to biotic and abiotic breakdown processes, leaching and microbial decomposition have been studied using tethered leaves and litter bags. the experimental sites were two adjacent areas of deciduous woodland. in one area (the castanea site) a mor-like moder humus form has developed under a stand dominated by coppiced chestnut, in the other a mull-like moder underlies a stand of coppiced beech (the fagus site).chestnut leaves in the c ...	1973	28308230
the breakdown and decomposition of sweet chestnut (castanea sativa mill.) and beech (fagus sylvatica l.) leaf litter in two deciduous woodland soils : ii. changes in the carbon, hydrogen, nitrogen and polyphenol content.	changes in the carbon, hydrogen, nitrogen and polyphenol content of chestnut and beech leaves were measured during the first year after fall.chestnut leaves had an initial carbon, hydrogen and nitrogen content (by weight) of 48.71%, 5.56% and 0.77% respectively; beech had a similar carbon and hydrogen content (47.77% and 5.36%) but less nitrogen (0.56%).both leaf litter types showed percentage increases in nitrogen content during the study period but only the beech showed absolute increases in n ...	1973	28308231
food, feeding rates and assimilation in woodland snails.	analyses of the faeces of seven species of woodland, litterdwelling snails (marpessa laminata, clausilia bidentata, oxychilus cellarius, o. alliarius, discus rotundatus, arianta arbustorum and hygromia striolata), showed that all feed predominently on higher plant material, be it living or dead. h. striolata and a. arbustorum took more chlorophyll-containing plant material than the other species, d. rotundatus had a significant amount of fungus in its faeces, while the faeces of o. cellarius and ...	1970	28309717
the tree drought emission monitor (tree demon), an innovative system for assessing biogenic volatile organic compounds emission from plants.	biogenic volatile organic compounds (bvoc) emitted by plants play an important role for ecological and physiological processes, for example as response to stressors. these emitted compounds are involved in chemical processes within the atmosphere and contribute to the formation of aerosols and ozone. direct measurement of bvoc emissions requires a specialized sample system in order to obtain repeatable and comparable results. these systems need to be constructed carefully since bvoc measurements ...	2017	28321263
cytotoxic triterpenoids isolated from sweet chestnut heartwood (castanea sativa) and their health benefits implication.	for centuries wood containers have been used in aging of wines and spirits, due to the pleasant flavors they give to the beverages. together with oak, sweet chestnut wood (castanea sativa) have been often used for such purpose. the maturation process involves the transfer of secondary metabolites, mainly phenolics, from the wood to the liquid. at the same time, other metabolites, such as triterpenoids and their glycosides, can also be released. searching for the extractable triterpenoids from sw ...	2017	28363853
