Colonial orb-weaving spiders provide insight into the proximate mechanisms by which social animals space themselves within a group. We examined mechanisms for the temporal patterns of web building that determine individual positions in Metepeira incrassata (Araneidae) colonies. The spiders display a characteristic age-related sequence of daily web building, with larger spiders completing their ...

The substantive issue of shaping local Chinese identity for social cohesion in the face of internal social disruption, external communist threats and international cold-war politics was one of the key policy challenges of the British colonial government. This article examines how education could support the formation and establishment of pro-British-government Chinese identities in colonial Hon...

In post-colonial India the female foeticide, a practice evolved from customary female infanticide of pre-colonial and colonial period, committed though in separate incidents, has made it almost a unified wave of mass murder. It does not fulfil the widely accepted existing definition of genocide but the high rate of abortion of legitimate girl-foetus by Indian parents makes their crime a kind of...

Group foraging provides predators with advantages in over-powering prey larger than themselves or in aggregating small prey for efficient exploitation. For group-living predatory species, cooperative hunting strategies provide inclusive fitness benefits. However, for colonial-breeding predators, the benefit pay-offs of group foraging are less clear due to the potential for intra-specific compet...

The history of disease and health in colonial Sri Lanka has been largely ignored. Historians of colonial economic and social policies in that country have produced a deluge of materials without mentioning the impact of colonial labour policy on the health of the indigenous people.' Meanwhile, even those who have written on the history of medicine in Sri Lanka have not fully accounted for coloni...

The relationship of the colonial morphology of Pasteurella pestis to its virulence has been controversial. Gotschlich (1900), Markl (1914), Petrie (1929), Burgess (1930), Otten (1936), Bhatnagar (1940) and Jawetz and Meyer (1943) described numerous colonial types for which interchangeable descriptions are lacking. Most agreed upon an inconstant hereditary transmission of colonial characteristic...

Although the colonial ideology often masks the fact, diplomacy has been a major part of the colonial encounter. In Canada, diplomacy in its many guises has been carried out between the colonizing Europeans and EuroCanadians since first contact between them. This diplomacy can be immediately broken up into at least two distinct periods: pre-colonial and colonial diplomacy. The first is marked by...

Coronary artery disease (CAD) is currently a prevalent disease from which many people suffer. Early detection and treatment could reduce the risk of heart attack. Currently, the golden standard for the diagnosis of CAD is angiography, which is an invasive procedure. In this article, we propose an algorithm that uses data mining techniques, a fuzzy expert system, and the imperialist competitive ...

I apply a comparative, functional group approach to coastal sandplain grassland taxa in order to examine whether rare plant species share certain aspects of rarity and life history characters that are distinct from their more common, co-occurring congeners in these habitats. I compiled a comparative data set containing 16 variables describing biogeographic distributions, level of imperilment, h...

Predation occurs when an organism completely or partially consumes its prey. Partial consumption is typical of herbivores but is also common in some marine microbenthic carnivores that feed on colonial organisms. Associations between nudibranch molluscs and colonial hydroids have long been assumed to be simple predator-prey relationships. Here we show that while the aeolid nudibranch Cratena pe...
