We might think of flowers in terms of their colour and scent, but what about their temperature? A new review in Annals of Botany looks at the thermal ecology of flowers. In the paper Casper van der Kooi and colleagues...
Species-level responses to environmental change depend on the collective responses of their constituent populations and the degree to which these populations are specialized to local conditions. Thermal tolerance limits...
Seed dormancy status regulates the response of seeds to environmental cues that can trigger germination. Anigozanthos flavidusĀ (Haemodoraceae) produces seeds with morphophysiological dormancy that are known to germinate...
Studies have indicated that plant stomatal conductance (gs) decreases in response to elevated atmospheric CO2, a phenomenon of significance for the global hydrological cycle. However, gs increases across certain CO2...
A mismatch between the thresholds of temperature and moisture for the onset of xylogenesis may increase forest vulnerability in semi-arid areas under forecasted warmer and drier conditions.
The results showed moderate thermal acclimation of respiration and no evidence for thermal acclimation of photosynthesis or local genetic adaptation for traits related to thermal acclimation.
Seed germination in the arid zone is a high-risk event. For grasses specifically, the ancillary bracts of the floret surrounding the seed have been associated with innate dormancy mechanisms, resulting in infrequent...
Although leaf wilt occurred in both water stress and FOC infection, the physiological responses were different, especially in leaf spatial distribution.
Climatic changes can result in modified leaf anatomy and gas exchange in arctic plants. In a one-year-old field experiment in Greenland, Schollert et al. investigate the effects of increased snow depth and warming on...
