Natural populations interact with each other in a variety of ways and, although most published ecological networks only include information about a single interaction type (e.g., feeding, pollinati...

Evolutionary emergence of size-structured food webs.

Explaining the structure of terrestrial and aquatic food webs remains one of the most important challenges of ecological theory. Most existing models use emergent properties of food webs, such as diversity and connectance as parameters, to determine other food-web descriptors. Lower-level processes, in particular adaptation (whether by behavioral, developmental, or evolutionary mechanisms), are...

Oh what tangled webs we weave…

A wide range of molecules in plants and animals have the capacity to form net-like structures to trap pathogens. In concert with antimicrobial compounds, these aggregates can become efficient killing machines. In other instances, as with the intracellular septins, such structures may constrain pathogenic organisms and direct them to an autophagic tryst with deadly lysosomes. Most curiously, a m...
