We evaluated differences in the rates and correlates of decomposition among 32 fern and angiosperm litter types collected in Hawai’i. Leptosporangiate ferns were separated into groups based on phylogeny: ‘polypod’ ferns, a monophyletic clade of ferns that diversified in the Cretaceous, and all other (‘non-polypod’) ferns that diversified earlier. We measured initial litter chemistry (nutrients ...
The taxonomic structure of yeast communities was studied in forest litter and soil, as well as in substrates transformed by the activity of Lumbricus terrestris earthworms (leaves in heaps, the gut contents, and coproliths). The activity of L. terrestris has a weak effect on the total yeast abundance but results in substantial changes in the community taxonomic composition. The share of ascomyc...
Environmental impacts of composting poultry litter with chemical amendments at the field scale have not been well quantified. The objectives of this study were to measure (i) P runoff and (ii) forage yield and N uptake from small plots fertilized with composted and fresh poultry litter. Two composting studies, aerated using mechanical turning, were conducted in consecutive years. Composted litt...
Saprophagous macroarthropods are important actors in litter decomposition as they process large amounts of and transform it into fecal pellets that differ chemical physical properties compared to ingested litter. When having a choice among several types, saprophagous exhibit feeding preferences depending on their nutritional requirements body size. However, how these affect feces is not well kn...
The objectives of this paper are to assess in laboratory conditions the flammability of undisturbed litter sampled beneath plants of seven species that are among those most frequently planted in hedges in Provence (southeastern France). Results were the variability in flammability recorded during burning experiments performed on undisturbed litter samples were partly explained by the proportion...
This work investigates the transformation, release and fate of inorganic matter during fluidised bed gasification poultry litter also mixed with limestone as an additive. The litter, cyclone ash were characterised by means chemical fractionation analysis, well X-ray diffraction. Concurrently, species feedstock was measured in separate laboratory experiments using molecular beam mass spectrometr...
Marine litter is any persistent, manufactured or processed solid material discarded, disposed of or abandoned in the marine and coastal environment. Ingestion of marine litter can have lethal and sub-lethal effects on wildlife that accidentally ingests it, and sea turtles are particularly susceptible to this threat. The European Commission drafted the 2008/56/EC Marine Strategy Framework Direct...
AIM The objective of the study was to evaluate the effect of deep litter housing and fermented feed on carcass characteristics and meat quality of crossbred Hampshire pigs. MATERIALS AND METHODS Forty-eight weaned crossbred Hampshire piglets of 2 months age (24 males and 24 females) were selected for the experiment. The piglets were randomly assigned into 4 homogenous experimental groups with...
Litter decomposition is the main driver of nutrient cycling process in terrestrial ecosystems. Afforestation completely altered vegetation composition and litter species, disrupting long-term carbon balance grassland ecosystem. However, there a lack understanding how mixing effect (LME) affects soil afforested Here, we investigated effects richness quality tree, shrub, grass species their mixtu...
