The Impact

The spatial variation of poplars’ reproductive phenology in Beijing’s urban area has aggravated the threat of poplar fluff (cotton-like flying seeds) to public health. This research explored the impact of microclimate conditions on the reproductive phenology of female Populus tomentosa in Taoranting Park, a micro-scale green space in Beijing (range <1 km). The observed phenophases covered flowering, fruiting, and seed dispersal, and ENVI-MET was applied to simulate the effect of the microclimate on SGS (start day of the growing season). The results showed that a significant spatial variation in poplar reproductive phenology existed at the research site. The variation was significantly affected by the microclimate factors DMT (daily mean temperature) and DMH (daily mean heat transfer coefficient), with air temperature playing a primary role. Specifically, the phenology of flowering and fruiting phenophases (BBB, BF, FF, FS) was negatively correlated with DMT (−0.983 ≤ r ≤ −0.908, p <0.01) and positively correlated with DMH (0.769 ≤ r ≤ 0.864, p < 0.05). In contrast, DSD (duration of seed dispersal) showed a positive correlation with DMT (r = 0.946, p < 0.01) and a negative correlation with DMH (r = −0.922, p < 0.01). Based on the findings, the increase in air convection with lower air temperature and decrease in microclimate variation in green space can be an effective way to shorten the seed-flying duration to tackle poplar fluff pollution in Beijing’s early spring.

Polynesia is a part of the world where tourism, especially focused on rich coral reefs, is an important part of the economy. But from the viewpoint of both tourism and conservation biology, it is one of the most threatened areas of the world. Here the ethical issues are somewhat different. How long can this dependence continue and at what cost? What is the ethical planning course for the Region?s national governments, not just in Polynesia, but throughout the Pacific? Like the general activities on the islands, tourism is heavily dependent on petroleum, both for bringing tourists and supplies and for maintaining them. Thus, the very industry that contributes so importantly to Polynesia?s economic viability also contributes significantly to human-induced global warming. As a region, Polynesia is particularly threatened by the accelerating impacts of global warming. Virtually all the islands are threatened by sea level rise, the atolls by inundation, and the high islands by flooding of infrastructure that is concentrated in low coastal areas. There are also the risks of increased and more intense tropical storms, as well as the risks to ocean ecosystems from rising temperatures and the increased acidification of ocean waters.
