Much of current ecological theory stems from experimental studies. These studies have often been conducted in closed systems, at spatial scales that are much smaller than the systems of interest. It is known that the outcome of these experiments may be seriously affected by artefacts associated with the caging procedures, as well as by the actual difference in spatial scale between experimental...

This paper presents the design of a new version of the Arena operating system targeted at real-time applications. Arena is a run-time operating system for parallel applications. The main principle of Arena is to provide predictable and controllable resource management. This is achieved by placing resource management at the user level of the system, thereby allowing any degree of application inf...

This meeting report presents the cutting-edge research that is developing around the waterflea Daphnia, an emerging model system in environmental genomics. Daphnia has been a model species in ecology, toxicology and evolution for many years and is supported by a large community of ecologists, evolutionary biologists and ecotoxicologists. Thanks to new advances in genomics and transciptomics and...

globalisation has given birth to medical tourism. health and medical tourism are the fastest growing seg­ments in not only developed nations but in developing countries too. india has become a hot des­tina­tion, as the indian medical standards match up to the highly prescribed international standards at a very low cost. however, it is an unmixed blessing; along with advantages, it has many unin...

Prorenin, the precursor of renin, exists in circulating blood at concentrations that are 5 to 10 higher than those of renin. For many years, prorenin was considered to be an inactive form of renin with no physiological role. Then, in the mid-80s of the last century, Luetscher et al reported that the levels of circulating prorenin (but not renin) are increased in diabetic subjects.1 Subsequent s...

The science of hypertension has been one of the success stories of modern medicine. The risks of high blood pressure have been defined, and through rigorous trials, effective treatments have been developed and shown to work. Pathophysiological mechanisms have been identified at least in part, and the future seems brighter as the full potential of molecular genetics is realized. A glance through...

Terrestrial isopods are known to be sensitive to humidity, brightness or temperature. Until now, aggregation was assumed to depend on these sensitivities as a result of individual preferences. In this paper, we show that the social component is also important in the isopod aggregation phenomenon. In experimental arenas with two identical shelters up to nearly 90% of woodlice aggregated under sh...

Five insecticides used by urban pest management professionals for ant control and three experimental insecticides were tested to determine whether these insecticides were horizontally transferred among individuals in colonies of Argentine ants, Linepithema humile (Mayr) (Hymenoptera: Formicidae). Ants were exposed to insecticide-treated sand for 1 min and then placed in a colony of untreated an...
