Climate change, climatic variation and extreme biological responses
Extreme climatic events could be major drivers of biodiversity change, but it is unclear whether extreme biological changes are (i) individualistic (species- or group-specific), (ii) commonly associated with unusual climatic events and/or (iii) important determinants of long-term population trends. Using population time series for 238 widespread species (207 Lepidoptera and 31 birds) in England...
متن کاملWill Extreme Climatic Events Facilitate Biological Invasions?
© The Ecological Society of America www.frontiersinecology.org E are experiencing not only gradual shifts in mean climate conditions but also dramatic changes in climate variability and prevalence of extreme climatic events (ECEs). ECEs such as droughts, floods, severe storms, and heat waves are changing in frequency, magnitude, timing, and duration, depending on the region and the specific cli...
متن کاملPaleoproterozoic snowball earth: extreme climatic and geochemical global change and its biological consequences.
Geological, geophysical, and geochemical data support a theory that Earth experienced several intervals of intense, global glaciation ("snowball Earth" conditions) during Precambrian time. This snowball model predicts that postglacial, greenhouse-induced warming would lead to the deposition of banded iron formations and cap carbonates. Although global glaciation would have drastically curtailed...
متن کاملImpacts of different climate change regimes and extreme climatic events on an alpine meadow community.
Climate variability is expected to increase in future but there exist very few experimental studies that apply different warming regimes on plant communities over several years. We studied an alpine meadow community under three warming regimes over three years. Treatments consisted of (a) a constant level of warming with open-top chambers (ca. 1.9 °C above ambient), (b) yearly stepwise increase...
متن کاملChange in climatic extremes over mainland China based on an integrated extreme climate index
An Integrated Extreme Climatic Index (IECI) is defined for analyzing the overall trend of change in the frequencies of major extreme climatic events over mainland China. The index is composed of 7 individual extreme indicators, i.e. the country-averaged frequencies of high temperature, low temperature, intense precipitation, dust storm and strong wind events, meteorological drought area percent...
