...C. Izsak; A. R. G. Price; J. T. Hardy; P. W. Basson We examine biodiversity in Tarut Bay, Saudi Arabia, around the effluent of a refinery that has operated since 1945. The spatial study involved quarterly assessment of diatom biodiversity in 1976/77 at 24 sites. Taxonomic distinctness decreased...

... regions, as does endemism, although levels of the latter are comparable for both regions. Values of taxonomic distinctness (Δ*), a relatedness measure based on average properties, are very similar for the Gulf and the Red Sea over all spatial scales. This might seem surprising, given that (i) the Gulf's...

Overall significant differences of community structure among both seasons and regions were detected. Depth and the distance from shore were important...

A high degree of consistency within surveyors was evident and, by modelling between-surveyor variations efficiently, expected trends in species richness and taxonomic distinctness were recovered. Moving from patterns to processes, the second aim was to test the effects of sea surface temperature...

Subsequent taxonomic assessment of the Rhinidae has determined that R . cf. djiddensis 1 is actually R. laevis while R . cf. djiddensis 2 is R. djiddensis...
