On the brink between extinction and persistence (2008)
Pertoldi, Cino, Bach, Lars A, Loeschcke, Volker
Abstract The nature of size fluctuations is crucial in forecasting future population persistence, independently of whether the variability stems from external forces or from the dynamics of the...

Abstract Background Winter migration of immature brown trout ( Salmo trutta ) into freshwater rivers has been hypothesized to result from physiologically stressful combinations of high salinity and...
Full genome gene expression analysis of the heat stress response in Drosophila melanogaster (2005)
Jesper G. Sørensen, Morten M. Nielsen, Mogens Kruhøffer, Just Justesen, Volker Loeschcke
Fabian M. Norry, Volker Loeschcke
One of the hypotheses of growing interest in studies of responses to thermal environments suggests that trade-offs and other trait associations may be altered by temperature. Here, the commonly...

Highland populations of several Drosophila species in Argentina were active early in the afternoon in the field as opposed to populations from a much warmer lowland site, where flies were mainly...

The effect of stressful (31°C) and nonstressful (25°C) growth temperatures on quantitative variation and developmental stability (fluctuating asymmetry) of Drosophila melanogaster was examined in a...
Nygaard Kristensen, Torsten, Løvendahl, Peter, Berg, Peer, Loeschcke, Volker
Although heat shock proteins (Hsps) are primarily considered as being intracellular, this study identified the presence of Hsp72 in plasma from female Holstein-Friesian dairy cattle. Plasma samples...
Full genome gene expression analysis of the heat stress response in Drosophila melanogaster
Sørensen, Jesper G., Nielsen, Morten M., Kruhøffer, Mogens, Justesen, Just, Loeschcke, Volker
The availability of full genome sequences has allowed the construction of microarrays, with which screening of the full genome for changes in gene expression is possible. This method can provide a...
Genome-Wide Analysis on Inbreeding Effects on Gene Expression in Drosophila melanogaster
Kristensen, Torsten Nygaard, Sørensen, Peter, Kruhøffer, Mogens, Pedersen, Kamilla Sofie, Loeschcke, Volker
The deleterious consequences of inbreeding, especially in the form of inbreeding depression, are well known. However, little is known about how inbreeding affects genome-wide gene expression. Here,...
Inbreeding by Environmental Interactions Affect Gene Expression in Drosophila melanogaster
Kristensen, Torsten Nygaard, Sørensen, Peter, Pedersen, Kamilla Sofie, Kruhøffer, Mogens, Loeschcke, Volker
Genomewide gene expression patterns were investigated in inbred and noninbred Drosophila melanogaster lines under benign and stressful (high temperature) environmental conditions in a highly...

Nielsen, Morten Muhlig, Sørensen, Jesper Givskov, Kruhøffer, Mogens, Justesen, Just, Loeschcke, Volker
The genetic architecture underlying heat resistance remains partly unclear despite the well-documented involvement of heat shock proteins (Hsps). It was previously shown that factors besides Hsps are...

Kristensen, Torsten Nygaard, Loeschcke, Volker, Hoffmann, Ary A
Artificially selected lines are widely used to investigate the genetic basis of quantitative traits and make inferences about evolutionary trajectories. Yet, the relevance of selected traits to field...
Costs and benefits of cold acclimation in field-released Drosophila
Kristensen, Torsten N., Hoffmann, Ary A., Overgaard, Johannes, Sørensen, Jesper G., Hallas, Rebecca, Loeschcke, Volker
One way animals can counter the effects of climatic extremes is via physiological acclimation, but acclimating to one extreme might decrease performance under different conditions. Here, we use field...
Metabolomic Signatures of Inbreeding at Benign and Stressful Temperatures in Drosophila melanogaster
Pedersen, Kamilla Sofie, Kristensen, Torsten Nygaard, Loeschcke, Volker, Petersen, Bent O., Duus, Jens Ø., Nielsen, Niels Chr., ...
While the population genetics of inbreeding is fairly well understood, the effects of inbreeding on the physiological and biochemical levels are not. Here we have investigated the effects of...

New candidate genes for heat resistance in Drosophila melanogaster are regulated by HSF
Jensen, Louise Toft, Nielsen, Morten Muhlig, Loeschcke, Volker
The cellular heat stress response is well studied in Drosophila in respect to the role of heat shock proteins (Hsp). Hsps are molecular chaperones, highly expressed during and after exposure to...
