Evolution: Love thy Neighbour
Five neighbouring populations of a cichlid fish from Lake Malawi differ in male courtship colour. Females show strong mate preferences for male coloration from their own populations. This suggests that sexual selection is an important factor contributing to speciation in cichlids.
متن کاملLove Thy Neighbour: Automatic Animal Behavioural Classification of Acceleration Data Using the K-Nearest Neighbour Algorithm
Researchers hoping to elucidate the behaviour of species that aren't readily observed are able to do so using biotelemetry methods. Accelerometers in particular are proving particularly effective and have been used on terrestrial, aquatic and volant species with success. In the past, behavioural modes were detected in accelerometer data through manual inspection, but with developments in techno...
متن کاملKnow Thy Neighbour: A Normative Theory of Synaptic Depression
Synapses exhibit an extraordinary degree of short-term malleability, with release probabilities and effective synaptic strengths changing markedly over multiple timescales. From the perspective of a fixed computational operation in a network, this seems like a most unacceptable degree of added variability. We suggest an alternative theory according to which short-term synaptic plasticity plays ...
متن کاملHonour Thy Neighbour—Clique Maintenance in Dynamic Graphs
Whenever objects and their interaction is modelled via undirected graphs, it is often of great interest to know the cliques of the graph. For several problems the graph changes frequently over time, and we therefore seek methods for updating the information about the cliques in a dynamic fashion to avoid expensive recomputations. This dynamic problem was investigated by Stix, and in this paper ...
متن کاملBorrowing from thy neighbour: a European perspective on sovereign debt
European capital markets show increasing concern about the extent of sovereign debts and their sustainability. Here we explore some insights that the Overlapping Generations (OLG) framework has to offer on such issues. The OLG framework implies, for example, that there is a limit to the amount of debt that may be sustained in a closed economy — with high debt raising interest rates and crowding...
