This book introduces recent progress in the study of species diversity
and community structures in terrestrial organisms conducted by three
groups at Kyoto University. First, it explains species diversity and the
functioning of fungi in Asian regions as outlined by metagenomic
approaches using next-generation sequencing technology. The advances in
high-throughput sequencing technologies accelerate the speed of species
inventorying, especially for microorganisms. Second, the study of
complex interactions between herbivorous insects and plants in the
community and ecosystem contexts is presented. Recent studies in
community and ecosystem genetics shed light on these complex
interactions with novel approaches incorporating genetic perspectives
including genetic variation and phenotypic plasticity in plant defenses
against herbivores. Finally, recent studies on speciation processes in
insects are described, processes that are related to the evolution of
particular life history strategies. Included is an examination of two
hypotheses that may be important in understanding diversification of
insect species in heterogeneous environments in space and time. This
book is a valuable resource especially for ecologists who are interested
in species diversity and community structure.
