Environmental and developmental physiology in the Arctic: The green sea urchin as a representative of planktonic developing marine larvae.

The ease of availability and the ecological and economic importance of S. droebachiensis make this species an excellent candidate for integrative studies of developmental physiology of marine organisms in Arctic ecosystems. We propose to conduct studies f undamental to establishing the green sea ...

Surviving without oxygen - from the role of hypoxia inducible factor to rebuilding a naturally damaged brain

While medical science has had a very limited success in counteracting the deleterious effects of ischemia/hypoxia in humans, evolution has repeatedly solved this problem.

Olfactory pathways connecting defined glomeruli of the macroglomerular complex to higher integration centres in the heliothine moth brain

The olfactory coding mechanism responsible for reproductive behaviour have been thoroughly investigated in heliothine moths.

Does ovarian fluid favour MHC-dissimilar sperm?

When males provide nothing but genes, female choice of mates is expected to favour individuals that can best increase offspring survival. This selection process may not only occur at an individual level, but also on the gamete level. Recent studies have i ndicated that the ova may select sperm on...
