Will the zoologists from Łódź discover new species of invertebrates in the Philippine tropics? A group of experts from the Faculty of Biology and Environmental Protection of the University of Lodz is preparing for the first expedition to the Philippines. Their targets include insects, arachnids and molluscs.
