Many non-equatorial species, including rodents such as hamsters, mice, and voles, are photoperiodic. In these species, changes in day length provide cues for the onset of their reproductive season. Alterations in photoperiod can result in profound morphological, physiological, a…

To understand the seasonal variation in phytoplankton size classes and the relative importance of microplankton, nannoplankton and picoplankton to total phytoplankton productivity, 14C photosynthetic rates and chl a of size-fractionated samples were investigated throughout the y…

Recent years have seen considerable advances in the study of biological rhythms and the underlying molecular mechanisms that drive the daily and seasonal physiology of vertebrates. Amongst teleosts the majority of work in this field has focused on the model species the zebrafish…

Teleost fishes occupy a range of ecosystem and habitat types subject to large seasonal fluctuations. Strategies for surviving theses seasonal environments can vary widely and are commonly accompanied by variation in brain structure. However, our understanding of how predictable …
