Abnormal fetuses and quality of litter

Животноводство России
Результаты эксперимента показали, что наличие мумифицированных и мацерированных плодов в помёте приводит к резкому снижению многоплодия свиноматок, но практически не влияет на крупноплодность животных.

Litter quality and litter removal by the native fauna in the western Chaco woodland of Argentina

Journal of Tropical Ecology, 2003
Most researchers assume litter decomposition to take place at the site where litterfall occurs, mostly by soil micro-organisms and microfauna of less than 1 mm in size. Accordingly, the litterbag method has become the standard technique for evaluating litter decomposition rates (Schlesinger 1985, Wedderburn & Carter 1999).

Litter quality, stream characteristics and litter diversity influence decomposition rates and macroinvertebrates

Freshwater Biology, 2006
Summary1. We examined the relative importance of litter quality and stream characteristics in determining decomposition rate and the macroinvertebrate assemblage living on autumn‐shed leaves.2. We compared the decomposition rates of five native riparian tree species (Populus fremontii, Alnus oblongifolia, Platanus wrightii, Fraxinus velutina and ...

Litter Decomposition in Yellowstone Grasslands: The Roles of Large Herbivores, Litter Quality, and Climate

Ecosystems, 2018
Plant litter decomposition is a key process that influences carbon and nutrient cycling in terrestrial ecosystems. Litter decomposition is controlled by a number of factors such as temperature, moisture, litter quality, and the composition of soil microbial communities. Large herbivores can affect litter decomposition by modifying each of these factors.

Ungulates decelerate litter decomposition by altering litter quality above and below ground

European Journal of Forest Research, 2016
Ungulates can greatly affect forest ecosystems’ functional characteristics. However, limited information is available about their influence on litter decomposition, a major ecosystem process, despite disturbance of ungulates on vegetation through selective browsing and trampling.

Land use, litter quality and climate effect on early stage litter decomposition [PDF]

, 2021
Litter decomposition represents one of the largest fluxes in the global terrestrial carbon cycle and a number of large-scale decomposition experiments have been conducted focusing on this fundamental soil process. The main factors affecting litter decomposition are the environmental conditions, litter quality and microbial community.

Control of leaf litter breakdown rates in streams by litter quality

2001
The importance of several leaf constituents in controlling rates of litter breakdown was assessed, a pivotal ecosystem process in forested headwater streams. Leaves of 26 tree or shrub species were assembled into monospecific packs (5 g dry mass), enclosed in coarse (1 cm) and fine mesh (0.5 mm) bags and exposed in a third-order mountain stream.

Litter Quality and Decomposition Rates of Foliar Litter Produced under CO2 Enrichment

1996
Decomposition of senesced plant material is one of two critical processes linking above- and below-ground components of nutrient cycles. As such, it is a key area of concern in understanding and predicting ecosystem responses to elevated atmospheric CO{sub 2}.
