Pollination mode and life form strongly affect the relation between mating system and pollen to ovule ratios

This essay examines the convergence of conceptualist poetics with evolutionary code as a form of ‘becoming alien’. The focus is Christian Bök's The Xenotext project: an attempt at translating a ‘short verse about language and genetics’, using a chemical alphabet, into a DNA sequence implanted into the genome of a polyextremophile bacterium capable of enduring conditions in outerspace. Bök describes the project as, ‘in effect, engineering a life-form so that it becomes not only a durable archive for storing a poem, but also as an operant machine for writing a poem – one that can persist on the planet until the sun itself explodes …’. The concrete, constraint-based character of Bök's project evokes a mode of writing between posthumanist aesthetics and a positivist grammatology by turns deconstructive and itself requiring of deconstruction.

Key Terms

The absence of a conceptual terminology, sufficiently developed and widely accepted in the Russian literature, significantly hinders progress in the field of reproductive biology of diatoms, restricts communication and debate, prevents training and transfer of knowledge. The present work is an attempt, based on world literature and our own research experience, to summarize, systematize, add, and clarify the existing terms, concepts and definitions related to research which are focused on sex and sexual reproduction in diatoms. A glossary of key terms (more than 200, including synonyms) is provided. Terms refer to diatom reproductive biology, life cycles, fertilization, mating system, gender (including inheritance and determination of sex, as well as inheritance associated with sex). Contradictions between possible interpretations of certain terms are briefly discussed.

A new species of the genus Cimmerites Jeannel, 1928, C. maximovitchi sp. nov., is described from the Akhunskaya Cave and Labirintovaya Cave, both located in the Akhun Karst Massif on the Black Sea Coast of the West Caucasus (Krasnodar Territory, Russia). The new species is rather isolated within the genus Cimmerites and occupies an intermediate position between species related to C. kryzhanovskii Belousov, 1998 and species close to C. vagabundus Belousov, 1998. Though both C. maximovitchi sp. nov. and C. kryzhanovskii are still known only from caves, these species are quite similar in their life form to other members of the genus which are all true endogean species.
