“Species” definitions remain arbitrary, contentious, and vague. Ideally, species are similar groups of locally adapted organisms capable of actual or potential interbreeding; natural populations that share variable genotypic-phenotypic characteristics dependent upon anscestrality-descendrality and environmental conditions or resources. However, these idealizations may lack common unifying features and suspend when applied to asexually reproducing (micro-)organisms, cryptids, hybrids, or isolated yet compatible taxa. Such suspended idealizations occasion the philosophically varied “Species Problem”. For example, realism posits species as extant noumena, while (subjective) pragmatism proposes species as extant instrumental phenomena and nominalism deems species as inexistent phenomena. Pluralism submits eliminative, inter-descriptive, paraconsistent, or trivial definitions contra-yet-pro aforementioned monist approaches. Thereby and overall, any categorical onto-epistemic “species” is already continuous one-multiple or “species pluralis“.
Consequently, “speciesism” or “human supremacism” and associated animal-rights and bioconservatist arguments suspend from skeptical-trivial “species pluralis“. If “species pluralis” is indeterminate, indifferent, and unstable in-the-last-instance, then exclusion-inclusion of non-human “species pluralis” actions, decisions, or intentions through anthropocentric Philosophies of Difference stands undecidable. For example, following naive-monist conceptions of species, animal-rights activists and vegans may protest animal experimentation or consumption based upon treatments with varied moral philosophies, but perform hetero-sentio-centric instrumentalism against immanently amoral and “insentient” autotrophic and heterotrophic (non-)organisms for “sentient” heterotrophs. All the same, such differential nescience of “species pluralis” for “species” suspends from ‘human microbiome’ and correlated ‘sorites paradox’.

Species pluralis asks: What are Trans-species Soundscapes? (Non-)Hypothesis: If species-species pluralis, then no more species than species pluralis; then no more species than non-species; then no more species pluralis than non-species pluralis. Performance-research proceeds according to suspended concepts and methods, i.e. “Species Problem” and Ecology-Music. Materials include compositions and samples of indifferent anthropic-biophonic-geophonic sounds, such as musical instruments, natural objects, and audio recordings (for-from) one-multiple “species pluralis“. Pseudo-replicated praxis results in non-directional listening untethered from “anthro-hetero-sentio-centric” ends.
