Secondary metabolites have a great potential as pharmaceuticals, but there are only a few examples where regulation of gene cluster expression has been correlated with ecological and physiological relevance for the producer. Here, signals, mediators, and biological effects of terrein production were studied in the fungus Aspergillus terreus to elucidate the contribution of terrein to ecological...

Biological market theory is potentially useful for understanding helping behaviour in animal societies. It predicts that competition for trading partners will affect the value of commodities exchanged. It has gained empirical support in cooperative breeders, where subordinates help dominant breeders in exchange for group membership, but so far without considering one crucial aspect: outside opt...

This paper describes a method of obtaining MOLS of order v = 2np for p a prime power. In particular, it gives 5,7 and 9 MOLS of orders 48,40 and 80 respectively. If x = Min(2p-1 ,2n-1 ,4n-2) , it is conjectured that x MOLS of order v are always-obtainable by this method. Australasian Journ::ll of ~ohmin::ltnrirc: 101 1QQLl \ n .... 17f.;;_1Qg::

in many countries, particularly developing countries, economic reforms, especially privatization, are considered as a strategic approach. the growth of the government decreases the competition in the market, and so, some fields should be privatized in order to create the competition.  by moving towards privatization and the changes in competition methods and the presentation of the world trade,...

In this paper we argue that flexible learning, as is prevailing among Australasian higher education institutions in recent years, is not without a price. Through a review of literature, we try to uncover provisos underpinning flexible learning. That is, all flexibilities come with provisos, pre-conditions, and commitments (or even inflexibilities). In order to make one aspect of the instruction...

At the intersection of consumer behaviour and plant competition is the concept of refuge-mediated apparent competition: an indirect interaction whereby plants provide a refuge for a shared consumer, subsequently increasing consumer pressure on another plant species. Here, we use a simple model and empirical examples to develop and illustrate the concept of refuge-mediated apparent competition. ...
