Climate warming is predicted to cause many changes in ectotherm communities, one of which is phenological mismatch, wherein one species' development advances relative to an associated species or community. Phenological mismatches already lead to loss of pollination services, and we predict that they also cause loss of biological control. Here, we provide evidence that a pest develops earlier du...

Phenology is the study of time and sequence of recurring stages in the life history of an organism. The occurrence fashions of the phenophases form different phenological behavior patterns. Despite the importance of phenology and wide applications of knowing phenophases, few studies have been done on the wooden species in Iran. The goals of this study are identification and designation of the p...

Wood chips are often used as solid fuel in modern biomass boilers. Experiments were conducted on 22 boilers located Serbia burning wood fuel. The influence of characteristics is analyzed relation to the flue gas losses and thermal efficiency boiler. Measured useful heat output tested was 460-2585 kW. Moisture content 19.21-38.23% with a net calorific value 10177-14139 kJ/kg ash 0.84-3.59%. Ther...

We evaluated the use of the Green-Red Vegetation Index (GRVI) as a phenological indicator based on multiyear stand-level observations of spectral reflectance and phenology at several representative ecosystems in Japan. The results showed the relationships between GRVI values and the seasonal change of vegetation and ground surface with high temporal resolution. We found that GRVI has the follow...
