A test of the coevolution theory of autumn colours: Colour preference of Rhopalosiphum padi on Prunus padus
Article Abstract:
Colonization of the aphid Rhopalosiphum padi on individual trees of Prunus padus in autumn is monitored and a strong preference of aphids for trees with green leaves is observed. Observations suggest that aphids colonizing trees with green leaves develop better in spring than aphids colonizing trees with bright autumn colours.

Macroecology of live-bearing in fishes: Latitudinal and depth range comparisons with egg-laying relatives
Article Abstract:
A study examines how fishes with contrasting reproductive modes differ in geographic range size and distribution. One hypothesis based on dispersal suggests that egg-laying taxa should occupy a wider range of latitudes than live-bearing, whereas the opposite prediction is derived from the idea that enhanced maternal input.
