Despite the early records of royal elephants in Brunei and Banjarmasin, there was no tradition of capturing and taming local wild elephants in Borneo. [2]
Besides the extant species, many species of ground sloths ranging up to the size of elephants (like Megatherium) inhabited both North and South America during the Pleistocene Epoch. However, they became extinct during the Quaternary extinction event around 12,000 years ago, along with most large animals across the Americas.
In the past, simple game theory models, such as the classic cooperative hunting and Prisoner's dilemma models, were used to determine decisions made by animals in cooperative relationships. However, complicated interactions between animals have required the use of more complex economic models such as the Nash equilibrium .
While the hyrax might look like a guinea pig, the African Wildlife Foundation reports that the little cuties are one of the elephant's closest living relatives, along with the manatee.
Elephantidae is a family of large, herbivorous proboscidean mammals collectively called elephants and mammoths. These are large terrestrial mammals with a snout modified into a trunk and teeth modified into tusks. Most genera and species in the family are extinct. Only two genera, Loxodonta (African elephants) and Elephas (Asian elephants), are ...
The Asian elephant (Elephas maximus), also known as the Asiatic elephant, is a species of elephant distributed throughout the Indian subcontinent and Southeast Asia, from India in the west to Borneo in the east, and Nepal in the north to Sumatra in the south. Three subspecies are recognised—E. m. maximus, E. m. indicus and E. m. sumatranus.
The elephants collapsed when the toxin impaired their motor functions and their legs became paralysed. Poaching, intentional poisoning, and anthrax were excluded as potential causes. [84] Elephants may also be host for a variety of parasites and bacteria such as Pasteurella, [85] Salmonella, Clostridium, [86] coccidian, nematode, and trematode ...
Diagram of the six possible types of symbiotic relationship, from mutual benefit to mutual harm. The definition of symbiosis was a matter of debate for 130 years. [7] In 1877, Albert Bernhard Frank used the term symbiosis to describe the mutualistic relationship in lichens.
