3 . Despite the difficulties, the California coastal ecosystem is improving, largely thanks to the huge appetite sea otters (海獭) have for crabs. In a creative study, scientists revealed the return of otters to their former habitat in a Central California river mouth has slowed the decrease of the area’s river banks by up to 90%. “It would cost tens of millions of dollars for humans to rebuild these stream banks and restore these rivers. The otters are stabilizing them for free, in exchange for an all-you-can-eat crab feast,” said biology professor Brian Silliman, Ph. D. at Duke University.

Like many California river mouths, Elkhorn once was a habitat for otters, which need to eat around 20 to 25 pounds of food every day, with crabs being one of their favorite meals. But after fur traders hunted the local otter population nearly to extinction, the number of crabs exploded over the next century. Crabs dig into salt river soil, and over time can cause a salt river to wear away and collapse. Today, years after the otters returned, rivers and stream banks became more stable.

Angelini, one of the study’s authors, said that tool is an encouraging sign for her team as they face similar threats to Florida’s coastlines from sea level rise, storms, and extra nutrients overflowing into coastal waters. “All these seem unsurmountable,” Angelini said. “However, this study shows that, if we truly understand the ecosystem and know what tools to use, we can see significant benefits to the health and stability of these systems.”

The research team conducted large-scale surveys across 13 tidal (潮汐的) streams, as well as small-scale field experiments at five locations around the river mouth over a six-year period. Otters were not included in some lest sites but allowed to be used in others, using a caging system designed by Angelini.

“And all these years later, we now see these amazing results. It’s an inspiring story about the benefits of conservation and persistent, long-term research,” Angelini said.

5 . In our family, the presents we gave one another were almost always homemade. I thought that was the definition of a gift: something you made for someone else. We made all our Christmas gifts: piggy banks from old bottles, and puppets from retired socks. It didn’t seem like a hardship to me; it was something special.

My father loves wild strawberries, so for Father’s Day my mother would almost always make him strawberry cakes. While we kids were responsible for the berries, we each got an old jar and spent the Saturday before the celebration in the fields, filling it as more ended up in our mouths. Finally, we returned home and poured them out on the kitchen table to sort out the bugs. I’m sure we missed some, but Dad never mentioned the extra protein.

In fact, he thought that was the best possible present, or so he had us convinced. It was a gift that could never be bought. As children raised by strawberries, we were probably unaware that the gift of berries was from the fields themselves, not from us. Our gift was time, attention, care and “red” fingers.

Gifts from the earth or from each other establish a particular relationship, a duty of sorts to give, to receive, and to exchange. The field gave to us, we gave to my dad, and we tried to give back to the strawberries. When the berry season was done, the plants would send out its red runners to make new plants. So I would weed out little fields of ground where the runners touched down. Sure enough, tiny little roots would emerge from the runner and by the end of the season there were even more plants, ready to bloom under the next strawberry season. No person taught us this — the strawberries showed us. Because they had given us a gift, an ongoing relationship opened between us.

9 . When I was young, our family cat broke out in a rash (皮疹). But an examination at the vet’s revealed no answers. When asked, “Has anything ________ in your home?” my mom explained my leave for college, and the vet responded “That’s it!” He gave my cat medicine that she took in my ________, and curiously didn’t need when I was home.

Years later after marriage, I adopted a well behaved cat. Suddenly he decided to ________ all our house plants. As it could be a ________ of his not feeling well, I took him to the vet. When tests all came back ________, the familiar question was asked again, “Has anything changed in your home?” We thought hard but couldn’t get it until one day we ________ our cat unsuccessfully trying to get in the window. Ah-ha! We had replaced the old ________ with new wooden blinds. They clearly ________ him from sitting in his favorite spot. Then I ________ the blinds every morning. The digging stopped.

I had forgotten those two incidents. Until recently our dog started ________ not herself and became an absolute________ on our daily runs. It was right when I was taking her to the vet that I thought of the question I would most ________ be asked. After years of being at home, I had recently gone back to work. It was a difficult ________ for our family, but I never considered the ________ it would have on one particular member of the family. Suddenly, she was ________ all day long in a quiet house. Why hadn’t I realized it before?

10 . When scientists talk about recent extinctions, birds and mammals (哺乳动物) get most of the attention. But the first global analysis of its kind finds it is twice as many plants that have disappeared as birds, mammals, and amphibians (两栖动物) combined.

Researchers reviewed published research, international databases, and museum specimens such as grasses from Madagascar, finding that 571 plants species have gone extinct in the past 250 years. One reason why the total is higher than that of the well-studied animals is that there are simply more species of plants. Looking at percentages, the situation is worse for mammals and birds. An estimated 5% of those species have gone extinct, compared with 0.2% of plants.

The loss includes the Chile sandalwood tree in the South Pacific, which was cut down for its fragrant (芳香的) wood. It was last seen on Robinson Crusoe Island in 1908. The extinction rates among plants have been highest for trees and shrubs on islands, which often have species that occur nowhere else, and in regions with rich diversity, especially the tropics and in Mediterranean climates.

Just a few years later, the world lost the banded Trinity (Thismia americana), a leafless plant that grew entirely underground except for its flowers. Most species of this kind of plant grow in rainforests, but this plant was first described in 1912 in a sandy wetland in Chicago, Illinois, and was wiped out by development.

According to the team’s report in Nature Ecology & Evolution, the total of 571 extinct plant species is four times higher than the official listing kept by the International Union for Conservation of Nature. Even so, it is probably still an underestimate (低估), as less is known about the status of plants in Africa and South America than on other continents. Many of these species may disappear, too. A major review of the status of global biodiversity recently estimated that more than a million species, including 14% of plant and animal diversity, are threatened with extinction.
