Geographic muting of changes in the Arctic sea ice cover [PDF]
The seasonal cycle in Arctic sea ice extent is asymmetric. Its amplitude has grown in recent decades as the ice has retreated more rapidly in summer than in winter.

The role of the hypothalamic-pituitary-adrenal axis in modulating seasonal changes in immunity.
Seasonal changes in environmental conditions are accompanied by significant adjustment of multiple biological processes. In temperate regions, the day fraction, or photoperiod, is a robust environmental cue that synchronizes seasonal variations in ...

CARBON STOCK GROWTH IN A SECONDARY ATLANTIC FOREST [PDF]
The secondary Atlantic forests play an important role in the context of climate change, acting as a carbon sink for the atmosphere. However, these forests can become a carbon source in case of increased tree mortality.

The changing seasonal climate in the Arctic [PDF]
Ongoing and projected greenhouse warming clearly manifests itself in the Arctic regions, which warm faster than any other part of the world. One of the key features of amplified Arctic warming concerns Arctic winter warming (AWW), which exceeds summer warming by at least a factor of 4.

Seasonal Patterns of Peak Expiratory Flow Rate in Young Healthy Individuals
Background: The seasonal changes are associated with changes in pulmonary functions including Peak Expiratory Flow Rate (PEFR). These changes are different among different population and location.
