Listen to part of a lecture by a biology professor, for next couple of weeks we ‘ll (be) focusing on how animals communicate with each other, up to now, we(‘ve) had a rather narrow view of (vocal) warnings (that) animals (give) each other, some resent research indicates (that) this communication system is a lot more complex than we(‘ve) traditionally thought, let (me) give you an example, take <prairie> dog, of cause they are nor really dogs at all, while we who lived on plain in western part of United States, in case we can’t visual them, let’s describe them to you, they are about (as big as) <squirrels> but with(out) the (bushy) tail, and unlike <squirrels>, they (live in) holes on the ground, and they spend a lot of time (just) outside their holes, because they have a lot of enemies, (hawk{[hɔːk]n.鹰,隼}, coyote{['kɔɪəʊt]n.小狼,山狗}), humans, you name it, when they (spot{[spɒt]v.点缀,侦察敌方目标} a) <potential> threat, they bark (to) their neighbor1 g/ ~, S0 o7 P3 ]
and then (escape) down into their holes, big deal, (you say, well, it turns out,) they can differentiate (among) <predators>, researchers discovered that the bark differs from different <predators>, (coyote) warning is different from people warning, (for instance,) but it goes deeper than that,
6 \7 ?4 d' d8 G& zthere is actually evidence that the barks <differential> (between) individual predators of the same species, the researchers found, (for example,) that (the prairie dogs) had (a) different bark for each of the research (team).
