Asymmetric effects between tree and understorey litters on mixed litter decomposition in temperate Quercus variabilis forest

Science of The Total Environment, 2022
Litter decomposition is a critical process of biogeochemical cycles of ecosystem. While growing evidences have shown the decomposition rates of litter mixture are different from those of single-species litters, the mutual effects between different functional type species in the mixture remain inconclusive.

Litter decomposition and nutrient release from monospecific and mixed litters: Comparisons of litter quality, fauna and decomposition site effects

Journal of Ecology, 2022
Abstract Litter decomposition and nutrient release are key processes for soil C and nutrient cycling. However, the relative importance of the effects of litter quality, fauna and decomposition site on litter decomposition remains poorly understood.

Review of mixed forest litter decomposition researches

Acta Ecologica Sinica, 2010
Abstract The litter plays an important role in forest ecosystems. Decomposition of mixed leaf litters has recently become an active research area because it mimics the natural state of leaf litters in most of forests. Many studies reported effects of mixing litters on their decomposition, ranging from positive, negative to neutral.

Decomposition dynamics in mixed‐species leaf litter

Oikos, 2004
Literature on plant leaf litter decomposition is substantial, but only in recent years have potential interactions among leaves of different species during decomposition been examined. We review emerging research on patterns of mass loss, changes in nutrient concentration, and decomposer abundance and activity when leaves of different species are ...

Sunlight and Soil–Litter Mixing: Drivers of Litter Decomposition in Drylands

2014
Decomposition of leaf litter is a key component of biogeochemical cycles but the mechanisms driving it in arid and semiarid ecosystems (drylands) remain unresolved. Here, we review recent findings that demonstrate dual roles of solar radiation (ultraviolet and photosynthetically active radiation) and soil–litter mixing as drivers of decomposition in ...

Long‐term responses of leaf litter decomposition to temperature, litter quality and litter mixing in plateau wetlands

Freshwater Biology, 2016
SummaryDecomposition of plant litter is a key process in the flow of energy and nutrients in ecosystems. The extent and mechanisms towards which climate warming will affect litter decomposition in plateau wetlands remains largely unknown.We conducted a two‐year litter decomposition experiment along an elevation gradient from 1891 to 3260 m in China ...

Temporal dynamics of mixed litter humification in an alpine treeline ecotone

Science of The Total Environment, 2022
Loss of plant diversity affects mountain ecosystem properties and processes, yet few studies have focused on the impact of plant function type deficiency on mixed litter humification. To fill this knowledge gap, we conducted a 1279-day litterbag decomposition experiment with six plant functional types of foliar litter to determine the temporal dynamic ...

Observations of mixed-aged litters in brown bears

Ursus, 2008
Abstract We report on 3 cases of mixed-aged litters (young born in different years) in brown bears (Ursus arctos); in 1 instance the cub-of-the-year (hereafter called cubs) died in the den. Two cases occurred in Sweden after mothers were separated from their young during the breeding season.

Effects of mixed-species litter on bacterial and fungal lignocellulose degradation functions during litter decomposition

Soil Biology and Biochemistry, 2020
Lignocellulose is the main component of forest litter. Due to the recalcitrance of coniferous litter, nutrient turnover is usually slower in coniferous plantations. Lignocellulose decomposition is reportedly rapid in mixed-species litter, but the underlying microbial metabolic pathways that may explain this rapid rate are not well-studied. We collected

Hypertrophic cardiomyopathy in a litter of five mixed-breed cats

Journal of the American Animal Hospital Association, 1999
A litter of five, 18-month-old, mixed-breed cats were determined to have hypertrophic cardiomyopathy (HCM). Although no overt clinical signs were present in any cat, systolic heart murmurs were present in each. Electrocardiograms were normal, while subjective interpretations of heart enlargement on radiographs were made on four cats.
