Zebras have a less efficient digestive system than ruminants but food passage is twice as fast. [15] Thus, zebras are less selective in foraging, but they do spend much time eating. The zebra is a pioneer grazer and prepares the way for more specialised grazers such as blue wildebeests and Thomson's gazelles. [9] Lions feeding on a zebra
Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally ( endothermic ), insects must rely on external sources to provide their heat ...

[ 9 ] [ 29 ] The plains zebra is a pioneer grazer, mowing down the upper, less nutritious grass canopy and preparing the way for more specialised grazers like wildebeest , which depend on shorter and more nutritious grasses below.

In Southern California, the temperature differences are approximately 4 °F in winter and 23 °F (2 °C and 13 °C) in summer. At the coast in Santa Monica , the average high in August is 75 °F (24 °C), while in Burbank , approximately 10 miles (16 km) inland, the average high in August is 95 °F (35 °C): a temperature gain of about two ...
The triple whammy of record warmth, very little snow and lack of ice in Wisconsin during the winter of 2023-24 has made headlines. The birds have noticed, too. Many species are migrating to the ...
