<P>Species Problems and Beyond offers a collection of up-to-date essays discussing from an interdisciplinary perspective the many ramifications of the ''Species Problem.'' The authors represent experts in the philosophy of biology, in species-level evolutionary investigations, and in biodiversity studies and conservation. Some of the topics addressed concern the context sensitivity of the term ''species''; species as individuals, processes, natural kinds, or as ''operative concepts''; species delimitation in the age of Big (genomic) Data; and taxonomic inflation and its consequences for conservation strategies.
