Elemental ratios in fresh-water plankton; implications for community structure and energy transfer in food webs

The transfer of energy through food webs will be determined by the "growth efficiency" in terms of carbon for the individual members of the foodweb. Recent studies have clearly confirmed that the elemental ratios of the food will be a major determinant to this energy transfer or "trophic efficien...

Functional genomics - protein expression and functions related to a protein, MepE, secreted from Methylococcus capsulatus (Bath).

Methylococcus capsulatus (Bath) is able to obtain all its carbon and energy from methane. It is the main constituent of Bioprotein, a single cell protein product based on natural gas (Norferm DA), and represents. the first product to be commercialised fro m a methanotroph. Considering the low cos...

Plural approaches in evolutionary biology: the adaptive significance of sex

This project attends a recent methodological development within evolutionary biology, i.e., the introduction of so-called pluralistic approaches, in which one attempts to explain evolutionary traits as phenomena emerging from a possibly complex interplay between different causal factors and proc...

DNA base excision repair at high temperatures

In all organisms, DNA bases are subject to chemical modifications causing cell death and/or mutagenesis if left unrepaired. Such damage can be enzymatically repaired by the base excision repair pathway (BER), which is initiated by removal of the modified base by a DNA glycosylase. The resulting ...

In vitro reprogramming of gene expression

Nuclear reprogramming can be defined as a change in nuclear function. Nuclear transplantation studies indicate that nuclear reprogramming is possible. However, ethical issues and availability of materials resulting from embryo cloning are significant limi tations for investigating mechanisms of r...

Mekanismer for læring av lukter hos insekter

Kondisjonering til lukter i forbindelse med næringsinntak er velkjent hos mange organismer, og er bl.a. vist hos insekter som bier og nattsvermerarter. Når disse insekters smaksorganer stimuleres med sukrose, strekker de ut sugemunnen 'proboscis' (ukondis jonert respons). Dette skjer vanligvis ik...

Development of biocompatible alginate capsules for cell therapy

Alginate has become one of the most useful immobilisation materials for living cells. A mixture of alginate and cells solidifies into beads that contain immobilised cells that allow free exchange of proteins, nutrients, and oxygen between the encapsulated cells and the host. The capsules exclude ...

Fungal genotyping, Cu-tolerance and host protection in ectomycorrhizal strains of the "Hymenoscyphus ericae aggregate" (Ascomycota).

Human activities as mining, melting, metal-processing and other industrial activities result in soils with toxic concentrations of heavy metals. Even though heavy metals significantly affect plant health, several higher plants grow in metalliferous enviro nments. All these plants are mycorrhizal,...

Game theory and interspecific arms races

Conflicts of interests between signalers or between signalers and signal receivers are common in animals, and may lead to coevolutionary arms races. Natural selection favours victim adaptations that help victims resist exploiters, but such adaptations are likely to be met with counter-adaptation...

The biological role of catalytic RNAs

We have discovered and characterized a new category of group I introns called the twin-ribozyme introns. The complex organizations of these introns reflect a dual biological role in intron splicing and expression of proteins from nucleolar DNA of eukaryot ic cells. A fundamental and general quest...

Molecular analysis of trade-offs in growth and reproductive allotment in a vital component of marine zooplankton

The appendicularia play a central role in marine ecosystems: 1) they are the second most abundant zooplankton after copepods, 2) they shortcut the microbial trophic loop, rapidly recycling nutrients to higher trophic levels, including commercially importa nt fish species, 3) the houses within whi...

Dynamics of genetic polymorphisms

The project will explore how well models and assumptions from theoretical population genetics fit to a real-life, natural population of Atlantic cod, by exploring the between- and within-generation dynamics of a select set of genetic polymorphisms. Differ ent classes of gene markers will be consi...

Seksuell preging og hybridisering mellom to arter av meiser (Paridae)

Siden de klassiske studiene til nobelprisvinner Konrad Lorentz, har seksuell preging blitt dokumentert hos en rekke dyrearter. Denne formen for læring har fått ny oppmerksomhet i senere år innen flere felt av evolusjonær økologi fordi man mener den er vik tig i forbindelse med hybridisering, arts...

The function of extrapair fertilization in passerine birds

In more than two thirds of all bird species with a socially monogamous mating system, females engage in copulations outside their pair bond. As a consequence, extrapair fertilizations and mixed-paternity broods are common in many of these species. The sel ective advantage for female extrapair fer...

Why females are ornamented: female competition, male choice and immunocompetence

Seksuell seleksjon har de siste tiårene vært det mest studerte fagfelt innen atferdsøkologien og har ytt vektige bidrag til såvel evolusjonsteori som populasjons- og bevaringsbiologi. Sentralt innenfor dette fagfeltet står evolusjon av ornamenter, f.eks. fargerik fjærdrakt. Hittil har nesten all...

Taxonomy of allopolyploid species complexes of Sphagnum: evolutionary and ecological significance of polyploidy

Peat mosses (Sphagnum) has historically attracted much attention from systematists, and the taxonomy of many groups has been controversial. An important obstacle to achieving a stable taxonomy has been the abundant environmentally induced variation in mor phology, making it difficult to delimit d...
