17 cze 2024 · We found evidence of diel activity shifts in eight of 17 analyzed species, in which five species become 21.6 % more nocturnal and three species become 11.7% more diurnal in high disturbed areas.
7 kwi 2022 · Species extinction-risk footprints. Input–output analysis can also be applied at a species level to identify the locations and sectors of consumption which are driving the extinction-risk ...
Our geospatial workflow provides a straightforward approach to accurately map species ranges and the estimation of area of habitat (AOH) for conservation planning and decision-making. Conversely, procedures that refine expert-drawn range maps to obtain AOH risk producing biased estimates for local-scale applications.
30 maj 2014 · Current rates of extinction are about 1000 times the background rate of extinction. These are higher than previously estimated and likely still underestimated. Future rates will depend on...
Number of extinctions. Since 1970, then, the size of animal populations for which data is available have declined by 73%, on average. The decline for some populations is much larger; for some, it’s much smaller. And, in fact, many populations have been increasing in size. We cover this in the next key insight.
21 maj 2024 · The domino effect could lead to more species going extinct and eventually even to the collapse of entire ecosystems. With nearly one million plant and animal species currently under threat,...
