Systematics, Phylogeny And Acoustic Evolution In Field Crickets (Orthoptera, Grylloidea, Gryllinae)
(2018-03-06)
Since several decades, field crickets of the subfamily Gryllinae under order Orthoptera have been used as a model group by researchers working in the field of neuroethology, behavioural ecology and bioacoustics. Subfamily ...
Queen Succession in the Primitively Eusocial Wasp Ropalidia Marginata
(2018-01-04)
Social insects are the most dominant terrestrial fauna for the last 50 million years. This tremendous ecological success is accompanied by the fact that sociality has evolved multiple times independently and achieved highest ...
The Biology Of Two Sexes : A Study Of The Primitively Eusocial Wasp Ropalidia Marginata
(2009-05-21)
A striking feature of hymenopterans societies is the absence of male workers. Foraging, nest building, brood care and all other activities required for the functioning of the colony are carried out by the females. These ...
Sensory Ecology Of Acoustic Communication In The Tropical Bushcricket Genus Mecopoda : Mechanisms And Evolution Of Synchrony
(2009-07-10)
In this thesis, I characterise five species of the bushcricket genus Mecopoda with respect to their acoustic signals and morphology and investigate the phenomenon of acoustic synchrony in one of these five species: Mecopoda ...
Queens And Their Succerssors : The Story Of Power In The Primitively Eusocial Wasp Ropalidia Marginata
(2009-04-30)
Ropalidia marginata is characterized as a primitively eusocial wasp due to the absence of morphological differentiation between the queen and worker castes. Unlike other primitively eusocial wasps, however, the queen in ...
