1 . More than a score of Australian rare mammals have been killed by wild cats. These predators, which arrived with European settlers, still threaten native wildlife — and are too plentiful on the mainland to eliminate, as has been achieved on some small islands which were previously filled with them. But Alexandra Ross of the University of New South Wales thinks she has come up with a different way to deal with the problem. As she writes in a paper in the Journal of Applied Ecology, she is giving feline (猫科的) — awareness lessons to wild animals involved in re-introduction programs, in order to try to make them cat-conscious.
Many Australian mammals, though not actually extinct, are restricted to fragments of cat-free habitat. This will, however, put the forced migrants back in the sights of the cats that caused the problem in the first place. Training the migrants while they are in captivity, using stuffed models and the sorts of sounds made by cats, has proved expensive and ineffective. Ms Ross therefore wondered whether putting them in large natural enclosures with a scattering of predators might serve as a form of training camp to prepare them for introduction into their new, cat-ridden homes.
She tested this idea on a type of bandicoot (袋狸) that superficially resembles a rabbit. She and her colleagues raised two hundred bandicoots in a huge enclosure that also contained five wild cats. As a control, she raised a nearly identical population in a similar enclosure without the cats. She left the animals to get on with life for two years, which, given that bandicoots breed four times a year and live for around eight years, was a considerable period for them. After some predation (扑食) and probably some learning, she abstracted 21 bandicoots from each enclosure, attached radio transmitters to them and released them into a third enclosure that had ten hungry cats in it. She then monitored what happened next. The outcome was that the training worked. Over the subsequent 40 days, ten of the untrained animals were eaten by cats, but only four of the trained ones. One particular behavioral difference she noticed was that bandicoots brought up in a predator-free environment were much more likely to sleep alone than were those brought up around cats. And when cats are around, sleeping alone is dangerous. How well bandicoots that have undergone this extreme training will survive in the wild remains to be seen. But Ms Ross has at least provided reason for hope.

8 . Also of interest...in family dramas
The Travelers
by Regina Porter (Hogarth, $27)
Though Regina Porter’s formally daring first novel “can feel too much like a jigsaw puzzle,” it achieves a “simply stunning” level of complexity, said Meng Jin in the San Fracisco Chronicle. As the first-time novelist tells the stories of two Georgia families — one black, one white — she weaves together events from 1946 to 2010 while deftly shifting between play-like dialogue, straight narrative, and various other modes. Not one character is a mere extra, and the impressive result “looks very much like life.”
Ask Again, Yes
by Mary Beth Keane (Scribner, $27)
Mary Beth Keane’s new novel is “one of the most unpretentiously profound books I’ve read in a long time,” said Maureen Corrigan in NPR.org. In 1973 New York City, two rookie cops forge a friendship that shapes the lives of the Irish-American families they raise side by side in a nearby suburb. Because each chapter is told from a new perspective, we come to know almost every member of those families, and Keane “beautifully dramatizes” how lives are built on a series of happenstances, including tragic ones.
Native Country of the Heart
by Cherrie Moraga (Farrar, Straus & Giroux, $26)
“This memoir’s beauty is in its fierce intimacy,” said Roy Hoffman in The News York Times. Playwright Cherrie Moraga makes her mother the heroine of the book, bringing the late immigrant’s story to life “with a poet’s verve.” Mexican-born Elvira Moraga, who picked cotton in California at 11, sold cigarettes in Tijuana at 14, and never learned to read, became the heart and soul of a large extended family. Here, she’s a character too resonant to be merely emblematic.
The Edge of Every Day
by Marin Sardy (Pantheon, $26)
Mental illness leaves no one in a family untouched, said Alison Van Houten in Outside. In a book whose nonlinear structure “mimics the erratic nature of schizophrenia,” essayist Marin Sardy bringing the describes how the disorder struck her mother and a brother, scrambling life for all the children. Her mother’s paranoid delusions disrupted their schooling; years later, Sardy’s brother, after refusing help, committed suicide. “How does one lead any semblance of a normal life under such circumstances?” Sardy shows us how.
Note:
1. resonant: 共振的,共鸣的 2. emblematic: 象征的,典型的
3. nonlinear: 非线性的 4.schizophrenia: 精神分裂症
