...Kevin T. Roberts; Andre Szejner-Sigal; Philipp Lehmann ABSTRACT In seasonal environments, many animals, including insects, enter dormancy, where they are limited to a fixed energy budget. The inability to replenish energetic stores during these periods suggests insects should be constrained by pre...

...David L. Denlinger ABSTRACT Diapause, a stage-specific developmental arrest, is widely exploited by insects to bridge unfavorable seasons. Considerable progress has been made in understanding the ecology, physiology and evolutionary implications of insect diapause, yet intriguing questions remain...

...Laura van Rosmalen; Jayme van Dalum; David G. Hazlerigg; Roelof A. Hut ABSTRACT To optimally time reproduction, seasonal mammals use a photoperiodic neuroendocrine system (PNES) that measures photoperiod and subsequently drives reproduction. To adapt to late spring arrival at northern latitudes...

... for seasonal changes in body temperature regulation is little explored. Here, we present novel data on the regulation of avian body temperature to investigate how birds alter mechanisms of heat production and heat conservation to deal with variation in ambient conditions. We subjected dark-eyed juncos ( Junco...

... carinatus , was introduced to the USA in the 1940s and is now established in southern Florida. We measured bite force and the thermal sensitivity of sprinting of L. carinatus during the winter and spring to determine how morphology and performance varied seasonally. We found evidence of seasonal variation...

This may be the case in the cricket Allonemobius socius , where warm environments (both seasonal and geographical) produced crickets with lighter cuticles...

To examine possible physiological divergence between these taxa, we measured metabolic...

...Barbara Helm; Ingrid Schwabl; Eberhard Gwinner SUMMARY To anticipate seasonal change, organisms schedule their annual activities by using calendrical cues like photoperiod. The use of cues must be fitted to local conditions because schedules differ between species and habitats. In complete absence...
