Sexual selection constrained by life history in a butterfly

Sexual selection and human life history.

The evolution of alternative developmental pathways: footprints of selection on life-history traits in a butterfly.

Developmental pathways may evolve to optimize alternative phenotypes across environments. However, the maintenance of such adaptive plasticity under relaxed selection has received little study. We compare the expression of life-history traits across two developmental pathways in two populations of the butterfly Pararge aegeria where both populations express a diapause pathway but one never expr...

Functional genomics of life history variation in a butterfly metapopulation.

In fragmented landscapes, small populations frequently go extinct and new ones are established with poorly understood consequences for genetic diversity and evolution of life history traits. Here, we apply functional genomic tools to an ecological model system, the well-studied metapopulation of the Glanville fritillary butterfly. We investigate how dispersal and colonization select upon existi...

Accommodating natural and sexual selection in butterfly wing pattern evolution.

Visual patterns in animals may serve different functions, such as attracting mates and deceiving predators. If a signal is used for multiple functions, the opportunity arises for conflict among the different functions, preventing optimization for any one visual signal. Here we investigate the hypothesis that spatial separation of different visual signal functions has occurred in Bicyclus butter...

Life history and larval performance of the Joker butterfly, Byblia ilithyia (Lep.: Nymphalidae)

دورهی نشو و نمای پروانهی Byblia ilithyia Drury، تأثیر نوع تغذیه روی ویژگیهای لاروی و طول چرخهی زندگی آن روی گیاه میزبان Tragia plukenetii A. R. Smith برای اولین بار شرح داده میشود. این مطالعه طی سال 2007 در پردیس دانشگاه Andhra و ناحیهی Zoo Park واقع در 5 کیلومتری پردیس، در شهر Visakhapatnam ('42 °17 N،'18 °82 E) در جنوب هندوستان انجام شد. طول چرخهی زندگی پروانهی مذکور 30/1 ± 20/19 روز بود (تخم...
