Geographic mosaic of selection by avian predators on hindwing warning colour in a polymorphic aposematic moth
Rönkä, Katja; Valkonen, Janne K.; Nokelainen, Ossi; Rojas, Bibiana; Gordon, Swanne; Burdfield‐Steel, Emily; Mappes, Johanna (Wiley-Blackwell, 2020)Warning signals are predicted to develop signal monomorphism via positive frequency‐dependent selection (+FDS) albeit many aposematic systems exhibit signal polymorphism. To understand this mismatch, we conducted a large‐scale ... -
Weak warning signals can persist in the absence of gene flow
Lawrence, J. P.; Rojas, Bibiana; Fouquet, Antoine; Mappes, Johanna; Blanchette, Annelise; Saporito, Ralph A.; Bosque, Renan Janke; Courtois, Elodie A.; Noonan, Brice P. (National Academy of Sciences, 2019)Aposematic organisms couple conspicuous warning signals with a secondary defense to deter predators from attacking. Novel signals of aposematic prey are expected to be selected against due to positive frequency-dependent ... -
Evolution of signal diversity : predator-prey interactions and the maintenance of warning colour polymorphism in the wood tiger moth Arctia plantaginis
Rönkä, Katja (University of Jyväskylä, 2017)Aposematic organisms avoid predation by advertising defences with warning signals. The theory of aposematism predicts warning signal uniformity, yet variation in warning coloration is widespread. The chemically defended ... -
Context-dependent coloration of prey and predator decision making in contrasting light environments
Nokelainen, Ossi; de Moraes Rezende, Francisko; Valkonen, Janne K.; Mappes, Johanna (Oxford University Press (OUP), 2022)A big question in behavioral ecology is what drives diversity of color signals. One possible explanation is that environmental conditions, such as light environment, may alter visual signaling of prey, which could affect ... -
Genetic colour variation visible for predators and conspecifics is concealed from humans in a polymorphic moth
Nokelainen, Ossi; Galarza, Juan A.; Kirvesoja, Jimi; Suisto, Kaisa; Mappes, Johanna (Wiley-Blackwell, 2022)The definition of colour polymorphism is intuitive: genetic variants express discretely coloured phenotypes. This classification is, however, elusive as humans form subjective categories or ignore differences that cannot ...
