Resistance to the Cabbage Aphid (Brevicoryne brassicae) in Brassica Plants [PDF]

Nature, 1963
A MARROW-STEM kale (Brassica oleracea var. acephala) selection segregated on selfing for plants with and without cuticular wax on their leaves, and it was observed in a natural field infestation that the non-waxy plants were not colonized by the cabbage aphid (Brevicoryne brassicae L.), whereas the normal, waxy plants had large colonies. The resistance

The Roles of Space and Food-Web Complexity in Mediating Ecological Recovery. [PDF]

Ecol Lett
We investigate how spatial configuration and food‐web complexity influence species recovery during landscape‐scale ecological restoration. We find that while the spatial arrangement of communities affects colonisation of empty patches, it does not impact recovery in already populated patches.
