: Canopy biology is the natural science that aimed at understanding of the biodiversity, biological processes, and ecological functions of forest canopies. Canopies determine the structural and energetic properties of forest ecosystems. Since the 1980s, canopy biology has progressed rapidly through the development of methods for accessing treetops. The rope climbing techniques used widely in canopy studies have developed from diverse procedures that allow human access to the top layers of forest vegetation. In comparison with other access hardware, e.g., cranes and gantries, rope assemblies have advantages in terms of user mobility, repeated access, and cost. The availability and safety of tree climbing techniques have improved with recent developments in mountain climbing gear and methodologies for their use. In this review, we use candidate studies to introduce the advantages, prospects and challenges of climbing techniques for tree canopy studies. Tree climbing allows excellent access to treetops in all (cid:879)(cid:882)(cid:887)(cid:913)(cid:847)(cid:884)(cid:2025)(cid:1881)(cid:880)(cid:854)(cid:916)(cid:887)(cid:852)(cid:634)(cid:903)(cid:872)(cid:870)(cid:917)(cid:884)(cid:2125)(cid:864)(cid:879)(cid:882)(cid:887)(cid:913) (cid:847)(cid:883)(cid:1373)(cid:2890)(cid:923)(cid:1394)(cid:1854)(cid:866)(cid:916)(cid:3486)(cid:3905)(cid:853)(cid:843)(cid:916)(cid:887)(cid:852)(cid:923)(cid:2015)(cid:849)(cid:872)(cid:845)(cid:635) types of forests, across all geographical locations. We expect further progress through combinations of rope climbing and other access methodologies. In the interests of safety and effectiveness, a platform should be developed for the distribution of relevant information to prospective tree climbing researchers and those who may wish to use the procedures for other activities, such as arboriculture.

Progress in ecological studies of soil fauna includes studies of the role and effects of soil fauna on decomposition and soil carbon dynamics in relation to global environmental changes, the introduction of molecular biology approaches to such studies, feeding habit analysis using stable isotopes, trait-based analysis of community ecology, and fine-scale experimental studies on the above/below ground relationship in ecosystems. In relation to this progress, six topics were reviewed: the function of soil fauna in the decomposition process; carbon sequestration in earthworms; the process of assemblage formation in earthworms; a trait-based approach to the collembolan community; food habit analysis using stable isotopes; and soil faunal impacts on plants.

: The clonal proliferation of neoplastic cells within a body and the clonal propagation of living organisms in a habitat are essential components of neoplastic and clonal population growth, respectively. In a favorable habitat, the number of clonal organisms increases exponentially up to the carrying capacity or to a niche size that reflects a specified sensitivity for environmental factors. This phenomenon corresponds to benign neoplasms in a body. For malignant neoplasms, neoplastic cells invade the surrounding tissue and metastasize to distant organs via the evolution of subclones that expand their niche size or carrying capacity by changing their genomes. This is an evolutionary mechanism that characterizes neoplastic cells in an organism, but has not yet been discovered for organisms other than bacteria. In humans, cancer cells treat medical treatments and the immune system as environmental disturbances within the organism. By accumulating genetic changes such as mutations, a neoplasm produces multiple subclones with differing genomic constitution. Such cell evolution can be represented as a phylogenetic tree. The spatial distribution heterogeneity of the habitat tissues, and limited dispersal ability of subclones. In conclusion, a comparison of the concept of clonality between the cell and organism levels would give new insights into research in both cancer biology and ecology.
