Among the sibling species of the AfrotropicalAnopheles gambiae complex, the nominal taxon (An. gambiae s.str.) is the major malaria vector. Its bionomics suggest a man-dependent speciation process which involves, in West Africa, various incipient species chromosomally recognized by different combinations of 2R paracentric inversions. One of the most recent(More)
Univariate and multivariate statistical analyses have been performed on 19 morphometric variables of adult male specimens belonging to three genetically identified species within Pseudoterranova decipiens (Nematoda: Ascaridida) parasitic in the digestive tract of seals. Two morphometric keys are proposed for the identification of the three species. One key,(More)
Analysis of the inversion polymorphism of Anopheles gambiae s.str. in The Gambia and surrounding zones of Senegal (Saloum and Casamance) shows, in samples from the central part of the study area, highly significant and temporally stable departures from Hardy-Weinberg equilibrium with deficits of the hetero-karyotypes. This situation and the general pattern(More)
We generalize the notions of strongly dominating and strongly unbounded subset of the Baire space. We compare the corresponding ideals and tree ideals, in particular we present a condition which implies that some of those ideals are distinct. We also introduce DUI -property, where I is an ideal on cardinal κ , to capture these two generalized notions at(More)
