Phenology of temperate trees in tropical climates.
Several North American broad-leaved tree species range from the northern United States at approximately 47 degrees N to moist tropical montane forests in Mexico and Central America at 15-20 degrees N. Along this gradient the average minimum temperatures of the coldest month (T (Jan)), which characterize annual variation in temperature, increase from -10 to 12 degrees C and tree phenology change...

متن کاملGlobal Influenza Seasonality: Reconciling Patterns across Temperate and Tropical Regions
BACKGROUND Despite the significant disease burden of the influenza virus in humans, our understanding of the basis for its pronounced seasonality remains incomplete. Past observations that influenza epidemics occur in the winter across temperate climates, combined with insufficient knowledge about the epidemiology of influenza in the tropics, led to the perception that cool and dry conditions w...
متن کاملTitle Fruiting and flushing phenology in Asian tropical and temperate forests: implications for primate ecology
19 In order to understand the ecological adaptations of primates to survive in 20 temperate forests, we need to know the general patterns of plant phenology in 21 temperate and tropical forests. Comparative analyses have been employed to 22 investigate general trends in the seasonality and abundance of fruit and young 23 leaves in tropical and temperate forests. Previous studies have shown that...
متن کاملLeaf out phenology in temperate forests
Monitoring phenology, the study of the timing of natural events, is an ancient practice that has experienced renewed interest in the wake of awareness of climate change. Spring onset has been occurring significantly earlier in temperate regions worldwide. Leaf out phenology is of particular interest because the emergence of leaves in the spring is extremely sensitive to temperature, and leaf ou...
