lechwe

1 Lechwe rest as the setting sun casts a purple glow over Botswana's Okavango Delta.

夕阳西下，博茨瓦纳的奥卡万戈三角洲被一片紫色的光辉所照耀，驴羚正在休息。

2 The reason this is interesting is that a lechwe mother is three times as likely to die while giving birth to a son (or during the subsequent week) as when she bears a dauhter.

之所以说这个现象有趣，是因为母羚羊因产雄性子羚羊而在分娩时（或随后一周内）引起的死亡率是生产雌性子羚羊的3倍。

3 The Delta is also the global stronghold for the red lechwe, a water-loving antelope.

4 Posterity will judge our generation harshly for having been responsible for depletions of rhinos, black lechwes and other species.”

5 The Nile lechwe, an antelope, is believed to be suffering in captivity because zoos are allocating less space to rare hoofed species.

6 The study in question was of Nile lechwe, an endangered antelope.

研究的对象是尼罗河驴羚，一个濒危的羚羊品种。
