Flying animals have had a major impact on nonflying organisms. Briefly consider the ecological and evolutionary interrelationships between pollinators and flowers, or between mosquitoes, the parasites they transmit and humans. Even a cursory glance at the manifold relationships flying insects have with all other forms of terrestrial life evaporates any doubt whether the world would be a very different place if they had never evolved.
Friday brings us many things. Many good things (besides the end of the week).
Today, the students taking the Biology and Taxonomy of Insects module on the Applied Ecology suite of MSc courses here at Harper Adams University were treated to a day consisting entirely of Hymenoptera-related (wasps, bees and ants) lessons, from Dr Andrew Polaszek, of the Natural History Museum (NHM) in London. Starting the day off with an overview of the Order, Dr. Polaszek went on to characterise the super-families using morphological and ecological definitions. The class later went on to try our hand at the initially daunting task of identifying specimens to super-family, family or genus level based on various keys. The fact that the majority of students were able to identify the specimens shows the quality of the keys and the direction Dr. Polaszek gave to us. By the end of the afternoon, most students had been identifying specimens for 2h30m, with the majority actively enjoying the process, and improving over the course of the day. Continue reading →
