Radical feminist Carla Lonzi is regarded as a founding mother of Italian feminism in the early 1970s. Italian feminists look at her diaries and pamphlets as historical testimony, or as tools of self-identification. Very little work engages Lonzi’s feminist thought in its critique of psychoanalytic constructs of female sexuality, such as the forced sexual coincidence between vaginal sexuality and masculine pleasure. While reappropriating the clitoris as the site of female autonomy, Lonzi invents the ‘donna clitoridea,’ whose authenticity opposes heteronormativity. This (...) article examines Lonzi’s theory of the clitoris and the donna clitoridea, arguing that Lonzi’s clitoris is not so much a site of pleasurable authenticity, but a phallic instrument of domination among women.

The evolutionary implications of environmental change due to organismic action remain a controversial issue, after a decades—long debate on the subject. Much of this debate has been conducted in qualitative fashion, despite the availability of mathematical models for organism–environment interactions, and for gene frequencies when allele fitness can be related to exploitation of a particular environmental resource. In this article we focus on representative models dealing with niche construction, ecosystem engineering, the Gaia Hypothesis and community interactions of Lotka–Volterra type, and (...) show that their quantitative character helps bring into sharper focus the similarities and differences among their respective theoretical contexts.
