Intimidating butterflies.
Many butterfly species feature two or four conspicuously coloured eyespots on their wings; the most commonly heard explanation for these markings is that they are used to intimidate predators. However, this explanation has stood, until recently, on the flimsiest of empirical foundations. Now, Adrian Vallin and colleagues have demonstrated empirically the effectiveness of these signals in dissua...
متن کاملMigrating to butterflies
Many of the stories that have appeared in this column recount the way in which the timely appearance of a paper catalyzed the pursuit of a new line of research. The experience is, happily, not limited to new papers. One of the greatest pleasures in research is to discover (or more accurately, to rediscover) a gem of a paper that has been in the literature for some time but whose findings or pro...
متن کاملA Genetic Analysis of the Fission-fusion Roosting Behavior of Tree-roosting Maternity Colonies of Big Brown Bats
The genetic variation between adjacent social groups is thought to be an important force in mammalian populations. When mating and dispersal behaviors are difficult to observe directly, estimates of genetic subdivision between social groups are used to infer mating and dispersal behavior and understand the distribution of genetic variation among social groups. Tree-roosting big brown bats (Epte...
متن کاملThunderstorms Don’t Get Butterflies
One important limitation on the accuracy of weather forecasts is imposed by unavoidable errors in the specification of the atmosphere’s initial state. Much theoretical concern has been focused on the limits to predictability imposed by small-scale errors, potentially even those on the scale of a butterfly. Very modest errors at much larger scales may nevertheless pose a more important practical...
متن کاملIrreversible Dynamos in Butterflies
We study the propagation of information in a network in the presence of permanent faults, to detect the patterns of initial faults which may lead the entire system to fail. Such patterns, called dynamos, have been already studied in diierent contexts and topologies, and under diierent laws of fault propagation. In our model each node assumes a new state according to the majority of the states o...
