1. Structure and Function of Odorant Binding Proteins and Chemosensory Proteins in Moths
Sammanfattning : Odorant Binding Proteins (OBPs) and Chemosensory Proteins (CSPs) are small soluble proteins found in the lymph of insect sensillae located on insect antennae. Odorant Binding proteins are implied in olfaction, by binding hydrophobic odorant molecules and transporting them to the olfactory receptor located on the dendrite of the olfactory neurons. LÄS MER
2. Spring Phenology of Butterflies : The role of seasonal variation in life-cycle regulation
Sammanfattning : Animals and plants in temperate regions must adapt their life cycle to pronounced seasonal variation. The research effort that has gone into studying these cyclical life history events, or phenological traits, has increased greatly in recent decades. LÄS MER
3. Unraveling the regulatory mechanisms of pupal diapause termination
Sammanfattning : Diapause is an essential part of many insect’s life cycle and is a developmental halt induced by environmental cues in advance of deteriorating conditions. Insects typically enter diapause to avoid unfavorable environmental conditions like low temperatures, poor food quality and the absence of conspecifics. LÄS MER
4. The role of insulin signaling during development, reproductive diapause and aging in Drosophila Melanogaster
Sammanfattning : The insulin/insulin-like growth factor signaling pathway exists from invertebrates to vertebrates and it can regulate various biological processes, including development, metabolism, stress resistance and lifespan. In Drosophila, eight insulin-like peptides (DILP1-8) have been found. LÄS MER
5. Functional genomics of diapause in two temperate butterflies
Sammanfattning : Natural selection will act on a given phenotype to maximize fitness in a particular environment, even if this would result in reduced fitness in other environments. In insects some of the strongest selection pressures act on timing life cycles to seasonal variation in environmental conditions, in order to maximize growth, reproduction, and to anticipate the onset of winter.
