Recent studies document linear elastic response of muddy marine sediments to load and deformation on temporal and spatial scales relevant to animal movement, with burrowers making openings for movement in such sediments by fracture. Cracks propagate through linear elastic solids in mode I (opening-mode crack growth) when the stress intensity factor (KI) at the crack tip exceeds the material’s f...

For grass species to spread efficiently through their environment requires seeds that can disperse over large distances and burrow into the ground. Recent work using awns from Hordeum murinum in conjunction with mathematical modelling shows that awn shape leverages environmental oscillations in order to produce these directional translations.

A twig-lining population of Latouchia swinhoei Pocock, 1901 (Ctenizidae) was found in Okinawa in a habitat also densely populated by other trapdoor spiders (Ryuthela nishihirai, Mesothelae). Specimens were tested in the laboratory for their utilization of objects offered to them for attachment to the rim of the burrow. The behavioural capacity of twig-lining is discussed in comparison with othe...

P HYLOANALYSIS, of which the late Dr. Trigant Burrow was the leading exponent, is a body of psychological theory dealing with the internal universe of behavior, the basic reactions that motivate men’s feelings, thoughts, and actions. Burrow held that it was humanity’s acquisition of language as a tool which caused men to deviate from the biological norm and led them into their present pathologi...

Belowground herbivory is commonly overlooked as a mechanism of top-down control in vegetated habitats, particularly in aquatic ecosystems. Recent research has revealed that increased densities of the herbivorous crab Sesarma reticulatum have led to runaway herbivory and widespread salt marsh die-off on Cape Cod, Massachusetts, USA. Aboveground herbivory is a major driver of this cordgrass habit...
