Photoperiod, diapause and cold-hardiness

open access: yesEuropean Journal of Entomology, 2004
Great progress has recently been made in cryobiology. One field, however, has been neglected: the temporal sequence of the effects of photoperiod and temperature, and their relative importance in cold hardening.

Locomotion in Response to Shifting Climate Zones: Not So Fast [PDF]

open access: yes, 2010
Although a species’ locomotor capacity is suggestive of its ability to escape global climate change, such a suggestion is not necessarily straightforward. Species vary substantially in locomotor capacity, both ontogenetically and within/among populations,
