Dragonfly Assemblages in Arid Tropical Environments: A Case Study from Western Namibia
Dragonflies have been proposed as indicators for the ecosystem health of freshwater wetlands. For their useful functioning as indicators it is, however, necessary to identify species compositions inExpand
Egg distribution, mate-guarding intensity and offspring characteristics in dragonflies (Odonata)
We studied how egg size, larval size and egg development time are related to oviposition site selection and mate guarding in a dragonfly assemblage of the Namib desert. Species that oviposited mainlyExpand
Invasion biology in non-free-living species: interactions between abiotic (climatic) and biotic (host availability) factors in geographical space in crayfish commensals (Ostracoda, Entocytheridae)
In invasion processes, both abiotic and biotic factors are considered essential, but the latter are usually disregarded when modeling the potential spread of exotic species. In the framework of setExpand
A field study of larval development in a dragonfly assemblage in African desert ponds (Odonata)
Aquatic animals distributed along a 'habitat-permanence' gradient (HPG), differ in life history (Wellborn et al., 1996. Annual Revue of Ecology and Systematics 27: 337--363). Dragonflies that occurExpand
Egg deposition rates and duration of oviposition in Platycnemis pennipes (Pallas) (Insects: Odonata)
Platycnemis pennipes deposits eggs into plant tissue at or just below the water surface. On a number of different plant species egg deposition rate was found to be similar, while oviposition durationExpand
Initial preference of oviposition sites: discrimination between living and dead plant material in Sympecma fusca and Coenagrion caerulescens (Odonata: Lestidae, Coenagrionidae)
Sympecma fusca and Coenagrion caerulescens mainly deposit their eggs into floating dead parts of emergent plants. In their initial choice of oviposition site (selection of landing site) S. fusca doesExpand

Increased fluctuating asymmetry in the damselfly Coenagrion puella is correlated with ectoparasitic water mites: implications for fluctuating asymmetry theory
The influence of ectoparasitic water mite larvae (Arrenurus) on the fluctuating asymmetry (FA) of forewing length and cell number in the foreweings of the damselfly Coenagrion puella has beenExpand
Completing the life cycle: detachment of an aquatic parasite (Arrenurus cuspidator, Hydrachnellae) from an aerial host (Coenagrion puella, Odonata)
Water mites are are very important parasites of aerial stages of aquatic insects. Their larvae parasitize semiaquatic hosts and must detach while the host is in a suitable habitat for reproduction ofExpand
An annotated checklist of the odonata of Namibia
Adult dragonflies (Odonata) are large powerful flying insects with enlarged wings and compound eyes, enabling them to chiefly prey upon other flying insects. The larval stages are aquatic and prey onExpand
