Sindre Fonkalsrud kicked off the meeting with his talk about a Norwegian pollination network. It is uncertain how much the recent decline in pollinators has been caused by land-use change or insecticides, or some other factor or combination of factors, thus it is timely to learn more about the which plants are visited by which insects. Sindre will be estimating properties of the network such as connectivity and modularity and hope to glean information about species diversity and robustness from his data. He is focussing mainly on hoverflies and bumble-bees, and has been conducting fieldwork on Havråtunet as well as using submissions to artsobservasjoner.no to form a regional-scale data-set.

Maria Lima is studying the bryophytes found in fertilised/unfertilised pastures in Rogaland. She will compare species richness and diversity of bryophytes under three fertiliser-level regimes: 1) no fertiliser, 2) animal manure, and 3) artificial fertiliser. Ten quadrats of 50 x 50 cm were sampled at each site with five on the ground and five on rocky sbustrate. The abundance of each species will be estimated, along with toal cover, presence of animal droppings as an indication of grazing intensity, and soil analyses of pH and loss-on-ignition.

Ynghild Storhaug is also studying pollinators and will use her study to test the ECOSET tool devised by Sandra Nogué-Bosch at the Biodiversity Institute of Oxford University. She has been observing honeybees and solitary bees at apple farms in Ullensang, Hordaland and has collected data on distance of the apple trees to the nearest hive and forest, recorded local temperatures, and apple production. An attempt to establish pan-traps encountered some practical difficulties unfortunately but may be able to provide some supporting data for some of the sites.

Thanks to the three Masters students for their presentations and to Alistair Seddon for organising the pizza and snacks.
