Flowering phenology in a species-rich temperate grassland is sensitive to warming but not elevated CO2.
* Flowering is a critical stage in plant life cycles, and changes might alter processes at the species, community and ecosystem levels. Therefore, likely flowering-time responses to global change drivers are needed for predictions of global change impacts on natural and managed ecosystems. * Here, the impact of elevated atmospheric CO2 concentration ([CO2]) (550 micromol mol(-1)) and warming (+...
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...
متن کاملPhenology 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 کاملRegulation of flowering in temperate cereals.
Long exposure to cold (vernalization) accelerates flowering in winter cereals, a process regulated by the VRN1 (approximately AP1), VRN2, and VRN3 (approximately FT) vernalization genes. Flowering during the fall is prevented by the VRN2 downregulation of VRN3 and low VRN1 transcription. Vernalization induces VRN1, which is followed by the downregulation of VRN2, thereby releasing VRN3. In the ...
متن کاملFlowering phenology in subalpine meadows: does climate variation influence community co-flowering patterns?
Climate change is expected to alter patterns of species co-occurrence, in both space and time. Species-specific shifts in reproductive phenology may alter the assemblages of plant species in flower at any given time during the growing season. Temporal overlap in the flowering periods (co-flowering) of animal-pollinated species may influence reproductive success if competitive or facilitative in...
