Mating success and potential male-worker conflict in a male-dimorphic ant [PDF]
Background Males of many species adjust their reproductive tactics with regard to their condition and status. For example, large males may develop weapons and fight for access to females, whereas small or undernourished males do not express costly ...

Beyond sex allocation : the role of mating systems in sexual selection in parasitoid wasps [PDF]
Funding: UK NERC Doctoral Training GrantDespite the diverse array of mating systems and life histories which characterise the parasitic Hymenoptera, sexual selection and sexual conflict in this taxon have been somewhat overlooked.

The repeatability of mating failure in a polyandrous bug [PDF]
Funding: NERC DTG ABE1-NERC13Mating failure, characterised by the lack of production of offspring following copulation, is relatively common across taxa yet is little understood.

Female mating decisions in the Trinidadian guppy, Poecilia reticulata [PDF]
Contrary to traditional belief, the decisions that females make before, during and after mating shape its outcome and ultimately fitness. The aim of this thesis was to examine how females modify and adjust their mating decisions in line with social and ...

The present study aimed to determine the presence of the sexual dimorphism based on the morphometric measurements in a total of 60 samples (♀: 26; ♂: 14, immature; 20) which were obtained in April 2017 from the population of Salaria fluviatilis which ...

Sexual conflict over mating frequency has driven the evolution of morphological and behavioural traits across taxa. Interactions may be termed ‘coercive’ and assumed to arise from conflict when male mating behaviours cause physical injury to females and ...
