FECUNDITY AND SPECIATION IN LAMPREYS [PDF]

open access: yesEvolution, 1963
With the exception of Petromyzon and Caspiomyzon, the various genera of holarctic lampreys each consists of several species, some of which are parasitic and others nonparasitic. In the latter, the socalled brook lampreys, sexual maturity is attained within a few months of metamorphosis, and as a result the adult feeding and migratory phase has been ...

The effects of six species of aphids on some life history parameters of the ladybird Propylea quatuordecimpunctata (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2005
One of the factors affecting the effectiveness of predatory coccinellids in an aphid infested crop is the food specificity of the predator. The response towards six species of aphids (Sternorrhyncha: Aphididae) was therefore tested in one of the most ...
