The evolutionary ecology of generalization: among-year variation in host plant use and offspring survival in a butterflyChrister Wiklund
Department of Zoology, Stockholm University, Stockholm SE 10691, Sweden

Enemy-free space and habitat-specific host specialization in a butterflyChrister Wiklund
Department of Zoology, Stockholm University, Stockholm, Sweden
Oecologia 157:287-94. 2008..These results show that larval survivorship on the same host plant species can be strongly habitat-specific, and suggest that enemy-free space is an underlying factor that drives feeding specialization in Papilio machaon...

Marginal eyespots on butterfly wings deflect bird attacks under low light intensities with UV wavelengthsMartin Olofsson
Department of Zoology, Stockholm University, Stockholm, Sweden
PLoS ONE 5:e10798. 2010..Consequently, prey adaptations that make predators attack less crucial body parts are expected to evolve. Marginal eyespots on butterfly wings have long been thought to have this deflective, but hitherto undemonstrated function...

Department of Botany, Stockholm University, SE 106 91 Stockholm, Sweden
Ecol Lett 13:330-7. 2010..In newly formed plant polyploids, novel interactions may alter habitat preferences and trait selection, and influence the further evolution of cytotypes...
Host plant preference and performance of the sibling species of butterflies Leptidea sinapis and Leptidea reali: a test of the trade-off hypothesis for food specialisationMagne Friberg

Contest outcome in a territorial butterfly: the role of motivationMartin Bergman
Department of Zoology, Stockholm University, SE 106 91 Stockholm, Sweden
Proc Biol Sci 277:3027-33. 2010..This study indicates that variation in resource value and motivational asymmetries are important for settling contests in butterflies...
Butterfly seed predation: effects of landscape characteristics, plant ploidy level and population structureLeena Arvanitis
Department of Botany, Stockholm University, Lilla Frescativ 5, 106 91 Stockholm, Sweden
Oecologia 152:275-85. 2007..This, in turn, may facilitate further divergence of ploidy levels...
Host-plant-induced larval decision-making in a habitat/host-plant generalist butterflyMagne Friberg
Department of Zoology, Stockholm University, SE 10691, Stockholm, Sweden
Ecology 91:15-21. 2010..Larval growth rates were similar between and within butterfly species and between host plants. Hence, we conclude that larval pathway decision-making in L. sinapis is an active response mediated by information from their host plants...
Intraspecific variation in body size and the rate of reproduction in female insects - adaptive allometry or biophysical constraint?David Berger
Department of Zoology, Stockholm University, 106 91, Stockholm, Sweden Evolutionary Biology Centre, Uppsala University, 752 36, Uppsala, Sweden
J Anim Ecol 81:1244-58. 2012..Conversely, inferences of constraint explanations on reproductive rates must take into consideration that adaptive scenarios may predict similar allometric exponents...
Ecological constraints on female fitness in a phytophagous insectDavid Berger
Department of Zoology, Stockholm University, Sweden

Residency effects in animal contestsDarrell J Kemp

Prey survival by predator intimidation: an experimental study of peacock butterfly defence against blue titsAdrian Vallin
Department of Zoology, Stockholm University, SE 10691 Stockholm, Sweden
Proc Biol Sci 272:1203-7. 2005..The killed peacocks were eaten, indicating that they are not distasteful. Hence, intimidation by bluffing can be an efficient means of defence for an edible prey...
Mating success of resident versus non-resident males in a territorial butterflyMartin Bergman
Department of Zoology, Stockholm University, Stockholm, Sweden
Proc Biol Sci 274:1659-65. 2007..We hypothesize that the proximate advantage of territory ownership is that light conditions in a large sunspot greatly increase the male's ability to detect and intercept passing receptive females...
Deimatic Display in the European Swallowtail Butterfly as a Secondary Defence against Attacks from Great TitsMartin Olofsson
Department of Zoology, Stockholm University, Stockholm, Sweden
PLoS ONE 7:e47092. 2012..This display appears directed towards predators but whether it is effective in intimidating predators so that they refrain from attacks has never been tested experimentally...
