Mapping the local dielectric constant of a biological nanostructured system
Beilstein Journal of Nanotechnology, 2021 The aim of this work is to determine the varying dielectric constant of a biological nanostructured system via electrostatic force microscopy (EFM) and to show how this method is useful to study natural photonic crystals.

Understanding antipredator strategies of insects: Human presence and escape behaviour in Odonata
Ecological Entomology, Volume 50, Issue 4, Page 682-692, August 2025.We tested urbanisation effects, along with a range of life‐history, environmental and contextual traits, on tolerance towards humans—measured by flight initiation distance—in 14 Odonata (dragonflies and damselflies) Urbanisation had a generally weak effect on Odonata escape behaviour; however, odonates delayed their escape at sites with high human ...

Predation by Larval Damselflies on Cladocerans
Journal of Freshwater Ecology, 2010 ABSTRACT We quantified the strike and capture efficiency, handling time, and functional response of Enallagma hageni and Ishnura verticalis larvae feeding on several sizes of the cladocerans Polyphemus pediculus, Daphnia pulex, and Holopedium gibberum. Both species were most efficient at capturing and ingesting P.

Can Hawaiian carnivorous caterpillars attack invasive ants or vice versa? [PDF]
, 2010 The Hawaiian Islands have allowed insects to evolve unique habits, because the islands are isolated and originally lacked predators, such as ants and wasps.

‘Nature of the year’ in Germany: An effective policy to raise public awareness?
People and Nature, Volume 7, Issue 7, Page 1593-1604, July 2025.Abstract Building public awareness for conservation can be done in different ways. However, the impact of the conservation marketing techniques is not well understood. The ‘nature of the year’ award is a public awareness building strategy for conservation in Germany, which aims to draw attention to annually selected species and their habitats. In order

Do lifetime contest costs affect the evolution of assessment strategies? A meta‐analysis
Journal of Animal Ecology, Volume 94, Issue 7, Page 1335-1345, July 2025.Our meta‐analysis reveals unexpected patterns in the evolution of assessment strategies during animal contests. We show that self‐assessment dominates in high‐cost fights, challenging existing theories. This study provides novel insights into the link between fighting costs and behavioural evolution, with implications for understanding fitness ...
