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/...

Catalogue of Texas spiders

This catalogue lists 1,084 species of spiders (three identified to genus only) in 311 genera from 53 families currently recorded from Texas and is based on the "Bibliography of Texas Spiders" published by Bea Vogel in 1970.

Peacock 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...
