Random foraging by herbivores: complex patterns may be due to plant architecture
Article Abstract:
Research was conducted to find out whether noctuid larvae foraging on the shrub Daphne laureola exhibited within-plant selection is caused by plant architecture. It was found that leaf whorls were at lower branching orders and shorter supporting stems when visited by larvae than whorls without record of noctuid larvae. Thus, it was speculated that plant architectural traits are used by the larvae as cues in selecting food with reduced cost of travel.

Hybrid origins of plant species
Article Abstract:
Natural occurrences of plant species hybridization are feasible despite the strict evolutionary conditions needed to produce them. Hybrid development is fostered through a suitable habitat and rapid chromosomal evolution. Although a selfing breeding system can enhance hybrid generation, it may be offset by lower hybridization rates among selfing taxa.

Plant competition underground
Article Abstract:
Belowground competition in plant species is more complex than aboveground competition. While aboveground competitors are favored by size in reaching available light, belowground competitors are selected by available soil resources, surface area, root density and plasticity in either enzyme properties in nutrient uptake or in root growth.
