Tough spiders
Spider graphs are the intersection graphs of subtrees of subdivisions of stars. Thus, spider graphs are chordal graphs that form a common superclass of interval and split graphs. Motivated by previous results on the existence of Hamilton cycles in interval, split and chordal graphs, we show that every 3/2-tough spider graph is hamiltonian. The obtained bound is best possible since there are (3/...
متن کاملPeacock spiders
How has the environment at the Champalimaud Neuroscience Programme influenced your work? We develop and use high resolution, dynamic, quantitative readouts of behavior. This is a real strength at the institute and strongly resonates with me due to the approach I developed while working on the cell biology of trachea morphogenesis. For me, biology is about regulating dynamic processes and if you...

Over the last three decades, the fossil record of spiders has increased from being previously biased towards Tertiary ambers and a few dubious earlier records, to one which reveals a much greater diversity in the Mesozoic, with many of the modern families present in that era, and with clearer evidence of the evolutionary history of the group. We here record the history of palaeoarachnology and ...
متن کاملSpiders’ webs
What is a spider’s web? Webs provide spiders with a means to trap their food and, in some cases, a place to shelter. Webs consist of blends of different silks, cleverly combined for functionality. Take the ‘typical’ orb web of the common garden spider (compare the photo on this page), which has evolved to take out-ofplane loads at optimized deflections. To be able to do so, this web needs to in...
