Selection for individual recognition and the evolution of polymorphic identity signals in Polistes paper wasps.
Individual recognition (IR) requires individuals to uniquely identify their social partners based on phenotypic variation. Because IR is so specific, distinctive phenotypes that stand out from the crowd facilitate efficient recognition. Over time, the benefits of unique appearances are predicted to produce a correlation between IR and phenotypic variation. Here, we test whether there is an asso...
متن کاملEvolution of identity signals: frequency-dependent benefits of distinctive phenotypes used for individual recognition.
Identifying broad-scale evolutionary processes that maintain phenotypic polymorphisms has been a major goal of modern evolutionary biology. There are numerous mechanisms, such as negative frequency-dependent selection, that may maintain polymorphisms, although it is unknown which mechanisms are prominent in nature. Traits used for individual recognition are strikingly variable and have evolved ...
متن کاملthe crisis of identity in jhumpa lahiris fiction: interpreter of maladies and the namesake
شکل گیری هویت(identity) مقوله مهمی در ادبیات پراکنده مردم(diasporan literature) می باشد. آثار جومپا لاهیری(jhumpa lahiri) ، نویسنده هندی آمریکایی، در سالهای اخیر تحسین منتقدین را به خود معطوف کرده است. وی در این آثار زندگی مهاجران و تلاش آنان برای پیدا کردن جایگاهشان در یک فرهنگ بیگانه را به تصویر کشیده است. این تجربه همواره با احساساتی نظیر دلتنگی برای گذشته، بیگانگی و دوری همراه است. با این ح...
15 صفحه اولRearing conditions influence quality signals but not individual identity signals in Polistes wasps
Given the diversity of animal signals, there has been recent interest in categorizing signals into probable functions according to their properties. For example, models predict that signals of quality should be costly and condition dependent, whereas signals of individual identity should be cheap and expressed independently of condition. Here, we test these predictions by comparing the conditio...
