1. Insect pollination of faba beans, Vicia faba : the abundance and foraging behaviour of different pollinators and their effect on crop yield
University essay from SLU/Dept. of EcologyAbstract : Faba beans, Vicia faba is known as a self-pollinating crop, however significant yield increases have been found in plants visited by honeybees and bumblebees. The bees either make positive visits, entering the flower and transferring pollen between different flowers resulting in cross-pollination, or negative visits, piercing the flower to “steal” nectar or collect nectar from extrafloral nectaries.

3. Effects of phenology and the microclimate on the seed set of Anemone nemorosa
University essay from SLU/Dept. of EcologyAbstract : Changing climate affects the dispersal and phenology of plants and pollinators. Particularly in the spring, climate warming accelerates the timing of flowering and insect emergence. Temporal mismatch is a fairly well studied biological phenomenon. READ MORE

4. Pollination biology of the endemic orchid Vanilla bosseri in Madagascar
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : The pantropical orchid genus Vanilla has a diverse floral morphology and there is a lack of knowledge about the pollination biology of its species in all geographical areas except the American tropics. The present study investigated the pollination biology of the endemic Vanilla bosseri Allorge in a dry, deciduous forest near Morondava at the west coast in Madagascar. READ MORE

5. Investigating the evolutionary consequences of sexual conflict through pollen and pistil traits in several Collinsia heterophylla (Plantaginaceae) populations
University essay from Lunds universitet/Examensarbeten i biologiAbstract : Abstract Sexual selection is considered to be one of the most important processes influencing the evolution and diversification of species. Sexual conflict, a subset of sexual selection theory, describes how opposing interests in the male and female reproductive systems can lead to one sex increasing its fitness at a cost to the other sex.
