Phenological Mismatch May Explain Population Decline of Lesser White-fronted Goose


Chinese Academy of Sciences
East Dongting Lake is one of the largest wintering site for Lesser White-fronted Goose Anser erythropus. However, its population size in this site has been declining significantly over the past decade, which might be related to the phenological mismatches between migratory birds and food availability.
Recently, researchers from the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences explored the consequences of water regime changes on phenological mismatches and detected the relative role of the mismatch as a driver of annual variations in abundance and distribution of the Lesser White-fronted Goose in East Dongting Lake. ....

Multiple Mare Flooding Events Occur inside Von Kármán Crater during Imbrian Period


Chinese Academy of Sciences
There had been at least three mare flooding events occurred inside the Von Kármán crater during the Imbrian period, according to a study by the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS).
The study was published in Icarus. It was conducted by the planetary mapping and remote sensing team led by Prof. DI Kaichang from the State Key Laboratory of Remote Sensing Science of AIR.
As of February 19, 2021, the “Yutu-2” rover had safely worked 27 lunar days (778 Earth days) and travelled a cumulative mileage of 652.62 meters inside the Von Kármán crater. The Von Kármán crater, lying in the northwest of the giant South Pole-Aitken (SPA) basin on the lunar farside, was formed 3.97 Ga ago in the pre-Nectarian period. ....
