On the fate of sexual traits under asexuality
Environmental shifts and life‐history changes may result in formerly adaptive traits becoming
non‐functional or maladaptive. In the absence of pleiotropy and other constraints, such traits …

The persistence and evolutionary consequences of vestigial behaviours
Behavioural traits are often noted to persist after relaxation or removal of associated
selection pressure, whereas it has been observed that morphological traits under similar …

Sex determination, sex chromosomes, and karyotype evolution in insects
Insects harbor a tremendous diversity of sex determining mechanisms both within and
between groups. For example, in some orders such as Hymenoptera, all members are …

DNA barcoding of crickets, katydids and grasshoppers (Orthoptera) from Central Europe with focus on Austria, Germany and Switzerland
We present a DNA barcoding study on the insect order Orthoptera that was generated in
collaboration between four barcoding projects in three countries, viz. Barcoding Fauna …

Parthenogenesis in Hexapoda: Entognatha and non‐holometabolous insects
In hexapods, unlike the majority of animals, development without fertilization is a common
phenomenon. They evolved a striking diversity of unisexual reproductive types that include a …

Neutral and selection-driven decay of sexual traits in asexual stick insects
Environmental shifts and lifestyle changes may result in formerly adaptive traits becoming
non-functional or maladaptive. The subsequent decay of such traits highlights the …

Weighing costs and benefits of mating in bushcrickets (Insecta: Orthoptera: Tettigoniidae), with an emphasis on nuptial gifts, protandry and mate density
GUC Lehmann - Frontiers in zoology, 2012 - Springer
Sexual selection is a major force driving evolution and is intertwined with ecological factors.

The role of hybridisation in the origin and evolutionary persistence of vertebrate parthenogens: a case study of Darevskia lizards
Obligate parthenogenesis is found in only 0.1% of the vertebrate species, is thought to be
relatively short lived and is typically of hybrid origin. However, neither the evolutionary …

Increased copulation duration before ejaculate transfer is associated with larger spermatophores, and male genital titillators, across bushcricket taxa
Copulation duration varies considerably across species, but few comparative studies have
examined factors that might underlie such variation. We examined the relationship between …
