Northward Expansion of Birds in China: A Response to Global Change
نویسندگان
چکیده
Based on the analysis of published data, 72 avian species (49 residents and 23 summer breeders) were found to expand northward in China during the past 30 years. The expansion distance of those birds varied from 11 kilometers to 1788 kilometers. The mean value of the expansion distance was 413.30 kilometers. The northward movement of birds was relevant to increasing temperature, NDVI and land-use pattern in northern China.

Northward expansion of paddy rice in northeastern Asia during 2000-2014.
Paddy rice in monsoon Asia plays an important role in global food security and climate change. Here we documented annual dynamics of paddy rice areas in the northern frontier of Asia, including Northeastern (NE) China, North Korea, South Korea, and Japan, from 2000-2014 through analysis of satellite images. The paddy rice area has increased by 120% (2.5 to 5.5 million ha) in NE China, in compar...
متن کاملCan changes in the distributions of resident birds in China over the past 50 years be attributed to climate change?
The distributions of bird species have changed over the past 50 years in China. To evaluate whether the changes can be attributed to the changing climate, we analyzed the distributions of 20 subspecies of resident birds in relation to climate change. Long-term records of bird distributions, gray relational analysis, fuzzy-set classification techniques, and attribution methods were used. Among t...
متن کاملBirds are tracking climate warming, but not fast enough.
Range shifts of many species are now documented as a response to global warming. But whether these observed changes are occurring fast enough remains uncertain and hardly quantifiable. Here, we developed a simple framework to measure change in community composition in response to climate warming. This framework is based on a community temperature index (CTI) that directly reflects, for a given ...
متن کاملDiversity of birds in eastern North America shifts north with global warming
The distribution of diversity along latitudinal and elevation gradients, and the coupling of this phenomenon with climate, is a pattern long recognized in ecology. Hypothesizing that climate change may have altered this pattern over time, we investigated whether the aggregate of reported northward shifts of bird ranges in North America is now detectable in community-level indices such as richne...
متن کاملEffects of climate change on water use efficiency in rain-fed plants
Water use efficiency (WUE) reflects the coupling of the carbon and water cycles and is an effective integral trait for assessing the responses of vegetated ecosystems to climate change. In this study, field experiments were performed to examine leaf WUE (WUEleaf) in response to changes in CO2 concentration and other environmental variables, including soil moisture and air temperature. We al...
