2 . With no special equipment, no fences and no watering, two abandoned agricultural fields in the UK have been rewilded (重新野化), in large part due to the efforts of jays, which actually “engineered” these new woodlands. Researchers now hope that rewilding projects can take a more natural and hands-off approach and that jays can shed some of their bad reputations.
The two fields, which researchers have called the New Wilderness and the Old Wilderness, had been abandoned in 1996 and 1961 respectively. The former was a bare field, while the latter was grassland—both lay next to ancient woodlands. Researchers had suspected that the fields would gradually return to wilderness, but it was impressive to see just how quickly this happened, and how much of it was owed to birds.
Using aerial data, the researchers monitored the two sites. After just 24 years, the New Wilderness had grown into a young, healthy wood with 132 live trees per hectare, over half of which (57%) were oaks. Meanwhile, the Old Wilderness resembled a mature woodland after 39 years, with 390 trees per hectare.
“This native woodland restoration was approaching the structure (but not the species composition) of long-established woodlands within six decades,” the researchers explained in the study.
Part of this reforestation was done by the wind, and researchers suspect that previous ground disturbance may have aided the woodland establishment—which is good news, as it would suggest that agricultural areas may be reforested faster than anticipated. However, animals—Eurasian jays, thrushes, wood mice, and squirrels—also played an important role in helping the forests take shape. This handful of species provided much of the natural regeneration needed for the forest to develop. Jays, in particular, seem to have done a lot of heavy lifting.

6 . The huge stone human statues of Easter Island have fascinated the world for centuries, but now a new research has solved one of the biggest mysteries (谜团) why the statues are located where they are.
Easter Island has more than 600 statues, built by different families hundreds of years ago. It is thought the statues represent their ancestors. However, it was previously a mystery why many of them were around the coast. While scientists have suggested the sites may have a connection with the island’s resources (资源), the latest research is the first attempt to look into such views.
Researchers focused on the east of the island, where various resources are located, and looked at the distribution (分布) of 93 statues built before European sailors arrived in the 18th century. After finding no connection with the rock used for the construction, they considered whether the statues were found near other important resources.
Things became interesting when they checked where the islanders got their drinking water. The island has no long-standing streams or lakes. However, fresh water brought by storm could pass through the ground and go deeper into the underground water system. “It is sort of amazing at low tide (潮水) when the water goes down, suddenly there are streams running off at different sites right at the coast that is just pure fresh water,” said Lipo. “We noticed, actually, when we were doing an investigation on the island, that we saw horses drinking from the ocean.”
The results of the new research—published in the journal Plos One—found that closeness to freshwater sites is the best explanation for the location of the statues, including why they appear inland as well as on the coast. “Historical records show the islanders also made wells to get drinking water,” said Lipo, adding that historic wells explained some inland statue locations that were apparently without natural water resources.
The results, said Lipo, made sense, as drinking water is important for the islanders and it is not practical to have to walk miles to get it.
