The 20th century encompasses one of the greatest waves of extinction, orelimination of species, to occur on the planet.

• Koala - biology.

  V REPRODUCTION Female koalas become sexually mature around 18 to 24 months of age. They can produce one offspring a year until they reach about 13 years of age. Males begin toproduce sperm around age 2 and, in the absence of older, stronger males, they may breed at that young age. More often, however, a male must grow big enough tocompete with other males for females, and mating generally begins for males at about 4 years of age. The breeding season for koalas is from October to May, during the...

The plant is very difficult toeradicate, and it has also clogged the channels of other Florida rivers.

Among the rivers flowing from the peninsula to the Gulf of Mexico are the Suwanne...

Only small portions of India’s rivers are navigable because of silting and the wide seasonal variation inwater flow (due to the monsoon climate). Water transport is thus of little importance in India. Barrages,...
