Larval growth rate is not a major determinant of adult wing shape and eyespot s...
Molleman, Freerk; Moore, M. Elizabeth; Halali, Sridhar; Kodandaramaiah, Ullasa; Halali, Dheeraj; van Bergen, Erik; Brakefield, Paul M.; Oostra, VicencioBackground Insects often show adaptive phenotypic plasticity where environmental cues during early stages are used to produce a phenotype that matches the environment experienced by adults. Many tropical satyrine butterflies (Nymphalidae: Satyrinae) are seasonally polyphenic and produce distinct wet- and dry-season form adults, providing tight environment-phenotype matching in seasonal environments. In studied ...
Digest: Habitat seasonality drives evolutionary change in plasticity in Bicyclu...
van Bergen, Erik; Oostra, VicencioCan changes in plasticity evolve in populations in response to local conditions? Zhen et al. addressed this question using populations of Bicyclus butterflies from Cameroon. The results of the study suggest that local adaptation in these African butterflies involved changes in the degree of plasticity, such that stronger responses to temperature were found in populations from habitats with stronger seasonal flu...

Hudson, Lawrence N; Newbold, Tim; Contu, Sara; Hill, Samantha L L; Lysenko, Igor; De Palma, Adriana; Phillips, Helen R P; Alhusseini, Tamera IThe PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical mod...
Adaptive developmental plasticity: Compartmentalized responses to environmental...
Mateus, Ana; Marques-Pita, Manuel; Oostra, Vicencio; Lafuente, Elvira; Brakefield, Paul M; Zwaan, Bas J; Beldade, PatríciaThe environmental regulation of development can result in the production of distinct phenotypes from the same genotype and provide the means for organisms to cope with environmental heterogeneity. The effect of the environment on developmental outcomes is typically mediated by hormonal signals which convey information about external cues to the developing tissues. While such plasticity is a wide-spread property...
Ecdysteroid Hormones Link the Juvenile Environment to Alternative Adult Life Hi...
Oostra, Vicencio; Mateus, Ana Rita A.; van der Burg, Karin R. L.; Piessens, Thomas; van Eijk, Marleen; Brakefield, Paul M.; Beldade, PatríciaThe conditional expression of alternative life strategies is a widespread feature of animal life and a pivotal adaptation to life in seasonal environments. To optimally match suites of traits to seasonally changing ecological opportunities, animals living in seasonal environments need mechanisms linking information on environmental quality to resource allocation decisions. The butterfly Bicyclus anynana express...
