Migrating 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 کاملNavigational mechanisms of migrating monarch butterflies.
Recent studies of the iconic fall migration of monarch butterflies have illuminated the mechanisms behind their southward navigation while using a time-compensated sun compass. Skylight cues, such as the sun itself and polarized light, are processed through both eyes and are probably integrated in the brain's central complex, the presumed site of the sun compass. Time compensation is provided b...
متن کاملI. Where to Find Butterflies
To observe butterflies in the field, we first need to locate them. This task is often not easy, as any experienced observer knows. A few abundant species, such as Cabbage Whites and American Ladies, can literally be found almost anywhere—roadsides, gardens, parks, even vacant city lots. But most others require at least some degree of specific knowledge to locate. And a surprisingly large number...
متن کاملMimetic Butterflies Introgress to Impress
The extent to which hybridization and the resulting interspecific gene flow (introgression) contribute to adaptation is a matter of great debate. On the one hand, fertile hybrids have the potential to transfer beneficial alleles between species [1] or even to spawn new species [2]. On the other hand, hybrids tend to have reduced fitness relative to parental species [3], which will often make th...
متن کاملMigrating to Processor Sharing
This paper describes experiences gained while adding processor sharing capabilities to the ARCADE distributed system. The goal of a processor sharing facility (PSF) is to allow busy users to take advantage of cycles available on idle processors, which are typically plentiful in a network of individually-owned machines. Several researchers have reported positive experiences with implementing a P...
