Why is the sand gazelle endangered?

Why is the sand gazelle endangered?

The distribution of sand gazelles Gazella subgutturosa marica in Saudi Arabia has declined dramatically during recent decades, apparently due to excessive hunting and habitat degradation. Today, sand gazelles survive only in small numbers in a few isolated parts of their former range.

Are sand gazelles endangered?

The Arabian sand gazelle (Gazella marica) or reem (Arabic: ريم‎) is a species of gazelle native to the Middle East, specifically the Arabian and Syrian Deserts….

How do gazelles survive in the desert?

Downsizing these oxygen-consuming organs allows the gazelle to breathe less often, decreasing water loss.

What do Arabian sand gazelles eat?

Arabian Sand Gazelles are typical intermediate feeders (browsing and grazing) becoming concentrate selectors during the wet season (grazing) with a preference for short grasses and forbs throughout their range.

How do sand gazelle conserve water?

A sand gazelle can shrink its liver to conserve water. Williams and his coworkers suggest that by shrinking their livers during times of extreme water shortages, sand gazelles decrease the number of active mitochondria. As a result, these animals “breathe less often and, over time, lose less water,” he says.

What do gazelles get eaten by?

Lions, leopards, cheetahs, hyenas, and wolves all hunt gazelles. Most gazelles live on open plains, where there is nowhere to hide. Instead they must be fast to escape their predators.

How do terrestrial animals conserve water?

Terrestrial animals lose water by evaporation from respiratory and body surfaces, excretion in urine, and elimination in the feces. They replace such losses by water in the food, drinking water when available, and retaining metabolic water formed in cells by oxidation of foods, especially carbohydrates.

Are there any Dama Gazelle left in the wild?
