Data from: Environmentally induced dispersal-related life history syndrome in the tropical butterfly, Bicyclus anynana

Marjo Saastamoinen, Paul M. Brakefield & Otso Ovaskainen
Dispersal is a key process for understanding the persistence of populations as well as the capacity of organisms to respond to environmental change. Therefore understanding factors that may facilitate or constrain the evolution of dispersal is of crucial interest. Assessments of phenotypic variation in various behavioural, physiological and morphological traits related to insect dispersal and flight performance are common, yet very little is known about the genetic associations among these traits. We have used experiments...

Data from: Identification of glucose kinase dependent and independent pathways for carbon control of primary metabolism, development and antibiotic production in Streptomyces coelicolor by quantitative proteomics

Jacob Gubbens, Marleen Janus, Bogdan I. Florea, Hermen S. Overkleeft, Gilles P. Van Wezel & Herman S. Overkleeft
Members of the soil-dwelling prokaryotic genus Streptomyces are indispensable for the recycling of complex polysaccharides, and produce a wide range of natural products. Nutrient availability is a major determinant for the switch to development and antibiotic production in streptomycetes. Carbon catabolite repression (CCR), a main signaling pathway underlying this phenomenon, was so far considered fully dependent on the glycolytic enzyme glucose kinase (Glk). Here we provide evidence of a novel Glk-independent pathway in Streptomyces coelicolor,...

Data from: Adaptability of large carnivores to changing anthropogenic food sources: diet change of spotted hyena (Crocuta crocuta) during Christian fasting period in northern Ethiopia

Gidey Yirga, Hans H. De Iongh, Herwig Leirs, Kindeya Gebrihiwot, Jozef Deckers & Hans Bauer
Many large carnivores readily use anthropogenic food sources, which often leads to conflict. Spotted hyenas (Crocuta crocuta) around the regional capital Mekelle, northern Ethiopia, feed on waste and to a lesser degree on livestock, but not on natural prey. We investigated the impact on their diet of the 55 day fasting period prescribed by the Ethiopian Orthodox Tewahedo Church, during which the vast majority of people do not consume animal products. We collected spotted hyena...

Data from: The predictive adaptive response: modeling the life history evolution of the butterfly, Bicyclus anynana, in seasonal environments.

Joost Van Den Heuvel, Marjo Saastamoinen, Paul M. Brakefield, Thomas B. L. Kirkwood, Bas J. Zwaan & Daryl P. Shanley
A predictive adaptive response (PAR) is a type of developmental plasticity where the response to an environmental cue is not immediately advantageous but instead is later in life. The PAR is a way for organisms to maximize fitness in varying environments. Insects living in seasonal environments are valuable model systems for testing the existence and form of PAR. Previous manipulations of the larval and the adult environments of the butterfly Bicyclus anynana have shown that...
