Leaf Litter as a Killer

Journal of Forestry, 1954
Abstract In addition to their passive role in forest soil development, dead leaves while still firm, often play in forestry the aggressive and important role of a villain. More often than is noted, abundant leaf litter exercises a serious adverse influence on the regeneration of desirable forest species in mixedwood.

Additives Enhancing Biodegradability in Plastics and Potential Implications for Textiles: A Mechanistic Review

Journal of Applied Polymer Science, EarlyView.
Mechanistic insights from additive‐assisted plastic degradation guide the design of environmentally adaptive textile fibers. Functional additives enhance oxidative, hydrolytic, enzymatic, and microbial degradation pathways. Translating these strategies requires control of fiber architecture, additive distribution, and environmental interactions ...

Role of soft tissue and bone interactions in the developmental integration and modularity of the skull in neural crest‐specific gap junction alpha‐1 knockout mice

The Anatomical Record, EarlyView.
Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...

Litter Decomposition of a Deciduous Tectona philippinensis and an Evergreen Parashorea malaanonan Across Contrasting Sites

Jurnal Sylva Lestari
Litter traits and site conditions alter nutrient inputs from deciduous and evergreen forests by influencing litter decomposition processes. Here, we investigated the leaf and stem mass loss rate (MLR) of a deciduous (Tectona philippinensis) and an ...

Contribution of Litter and Leaf Decomposition of Byrsonima gardneriana

Floresta e Ambiente, 2018
The litter in tropical ecosystems is one of the compartments responsible for the transference of nutrients to the soil, having great importance for the conservation and maintenance of biodiversity.

SOX6 is expressed in various cell lineages in the developing mouse heart and contributes to proper valvuloseptal development

The Anatomical Record, EarlyView.
Abstract Cells derived from the endocardium, epicardium, cardiac neural crest, and second heart field play a critical role in the formation of the valvuloseptal structures of the heart. Previous studies have shown that the expression of the transcription factor SOX9 in these cell populations is essential in the regulation of this process.

Nitrogen enrichment slows leaf litter decomposition rate in a mixed plantation of Cunninghamia lanceolata and Phoebe bournei: From the perspective of the leaf litter stoichiometric ratio

Trees, Forests and People
Leaf litter decomposition mediates critical ecosystem nutrient cycling processes and plays a pivotal role in regulating nutrient dynamics processes in subtropical forests.

CO2 emissions from reed litter in the air and on the soil surface in the Yellow River Delta, China

Frontiers in Environmental Science, 2023
The decay of litter in the air (that is, standing litter) and on the ground is an essential process of litter decomposition for many plant species.

7000 Years of Aboriginal Mining at Sugarloaf Hill in the Riverland Region of South Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Silcrete and chert are commonly represented in Aboriginal archaeological lithic assemblages across large parts of the southwestern Murray‐Darling Basin (MDB). In South Australia (SA), these materials were sourced from a series of quarries located along the incised course of the Murray River through the upper Riverland region.
