These adaptations mitigate nutrient loss by capturing the nutrients in falling detritus before the nutrients are absorbed and decomposed into the soil, and lost from leaching by the heavy rains. [16] The geologic, topographic and soil changes across wet tropical forest ecosystems have contributed to the astonishing biodiversity in biota we see ...
Steller's sea cow was the largest known sirenian to have lived, and could reach lengths of 9 metres (30 ft) [41] and weight of 8 to 10 tonnes (8.8 to 11.0 short tons). [44] A dugong's brain weighs a maximum of 300 grams (11 ounces), about 0.1% of the animal's body weight. [33]

Another factor causing the loss of rainforest is expanding urban areas. Littoral rainforest growing along coastal areas of eastern Australia is now rare due to ribbon development to accommodate the demand for seachange lifestyles. [47] Forests are being destroyed at a rapid pace. [48] [49] [50] Almost 90% of West Africa's rainforest has been ...
The roots of tropical ecology can be traced to the voyages of European naturalists in the late 19th and early 20th centuries. Men who might be considered early ecologists such as Alexander Von Humboldt, Thomas Belt, Henry Walter Bates, and even Charles Darwin sailed to tropical locations and wrote extensively about the exotic flora and fauna they encountered.
Gliding, in particular, has evolved among rainforest animals, especially in the rainforests in Asia (most especially Borneo) where the trees are tall and widely spaced. Several species of aquatic animals , and a few amphibians and reptiles have also evolved this gliding flight ability, typically as a means of evading predators.
Most big cats in Costa Rica are nocturnal or hide in trees in the rainforest like the margay. The most likely place to find a big cat is in the Simon Bolivar Zoo in San José, Costa Rica where there is a selection of all the native big cats along with other animals. Ocelots usually hunt on the ground at night and rarely climb trees.
Another reason is their tendencies to eat other whales and large prey animals such as seals and sea lions. [25] Orcas in Alaska are notable for their size; the adult female orca can reach the length of twenty-three feet (7.0 m) whilst the adult male orca can reach up to twenty-seven feet (8.2 m). [ 26 ]
