We report on the presence of magnetic iron oxides in the migratory ant Pachycondyla marginata. Magnetic particles were extracted from different parts of the ant (head, thorax and abdomen) using… Expand
Do neotropical migrant butterflies navigate using a solar compass?
Many tropical butterfly species are well-known for their migratory behaviour. Although these insects can maintain a constant direction throughout the day, the physiological mechanisms of orientation… Expand
Mitochondria as a Biosensor for Drug-induced Toxicity – Is It Really Relevant?
Mitochondria, from the Greek mito (thread) and chondros (grains) are small organelles that exist as a network in the cytoplasm of eukaryotic cells, performing a variety of important functions… Expand
An Algebraic Approach for H-matrix Preconditioners ∗ Suely
Hierarchical matrices (H-matrices) approximate matrices in a data-sparse way, and the approximate arithmetic for H-matrices is almost optimal. In this paper we present an algebraic approach to… Expand
