REM

The Scanning EM at the ZSM, a Leo 1430VP, is used by various scientists from both the ZSM and the Biozentrum of the LMU. Here we provide examples of recent and ongoing studies which use the conventional, low voltage, low vacuum, and QBSE modes.

Metamorphosis of flatfish head and visual system (Psetta maxima) (Konstanze Grundmann, Martin Heß) During metamorphosis the flatfish head undergoes striking anatomical changes. Starting from “usual” bilateral symmetry and “normal” swimming posture (top pictures) the right eye of the turbot migrates across the vertex (bottom pictures) to reach its final position on the left body side […]

Mandibular “oil presses” of Gondwanan pergid sawflies

Certain Australian sawflies have morphological adaptation that are unique among phytophagous insects. Modifications to the mandibles (mandibular “oil presses”) in the subfamily Perginae evidently allow them to deal with large amounts of essential oils in their host plants. This is a generalised mechanism for toxin elimination as opposed, for example, to the more usual enzymatic […]

Schmetterlingseier der Gattung Idaea Schmetterlingseier von Idaea serpentata (links) und Idaea filicata (rechts) (Geometridae, Spanner; Foto M. Junker). … wie ein Ei dem anderen gleicht – das gilt nicht für Schmetterlingseier, denn hier sind die Oberflächenskulpturen häufig arttypisch und von großem Interesse für die Zoologen. In der Schmetterlingssektion der ZSM wurde entdeckt, dass man mittels […]
