Two common strategies used to identify specific genes that influence aging in Drosophila melanogaster are overexpression screens and candidate gene approaches. Both of these strategies rely on gene expression systems. A ...

Alkylphenanthrenes such as retene (7-isopropyl-1-methylphenanthrene) are aquatic contaminants commonly found in anthropogenically-, industrially-, and petroleum-contaminated environments, and have been implicated in crude ...

The neuroendocrine basis of paternal behaviour is hypothesised to be homologous to that of maternal behaviour, with the expression of paternal behaviour resulting from the activation of estrogen-sensitive pathways in the ...

There has been a recent paradigm shift in the study of animal communication from examining interactions as dyads to considering interactions as occurring in a communication network. The dawn chorus of songbirds, a striking ...

Arsenic taken up by plants and fungi from contaminated soils can subsequently be introduced into food chains. Given the toxic properties of some arsenic compounds, this may be a cause for concern. Much remains to be learned ...

The mechanisms of plant response to nutrient limitation and utilisation are of great interest for agricultural purposes. Phosphate is a non-renewable resource and is one of the most important nutrients required for plant ...

Freshwater ecosystems face unprecedented levels of human-induced stresses and it is expected that the invasion of non-indigenous species will cause the greatest loss of biodiversity in lakes and rivers worldwide. Bythotrephes ...

The biological remains preserved in the sediments of Arctic lakes and ponds in the Canadian High Arctic are important indicators of environmental change, especially as long-term instrumental data are often lacking. Although ...

Every species has a limit to its geographic distribution. The problem is that we don’t really know why. Classical explanations propose that range limits occur where the ecological conditions overwhelm adaptation and ...

In multicellular organisms, apoptosis plays an important role in maintaining cellular homeostasis and removing damaged cells that present a threat to the integrity of the organism. Several lines of evidence suggest that ...
