The genus Diospyros‚ under family Ebenaceae‚ is composed of some 475 species common in tropical regions worldwide.

Today there are around 300 thousand chimpanzees in the wild and 2‚000 captive in the United States; out of those 2000‚ 850 are in laboratories‚ 600 in sanctuaries and 250 in private hands. (savethechimps.org). That lists chimpanzees as endangered species‚ rapidly decreasing in numbers. Being that chimpanzees are wild animals‚ their natural instincts are wild. Yes they are gentle loving creatures but what us humans don’t seem to comprehend is that they are wild animals‚ like lions‚ sharks‚

Sloths have many predators‚ like an jaguars and humans‚ there are many more but we are just going to talk about these. Jaguars are the top predator on the ground. Sloths go down to the forest floor once a week‚ and when they go they can’t protect themselves from jaguars. Humans shoot sloths so they can cut down their homes. When they shoot them they stay hanging in the tree because their claws have such a great grip‚ and the hunters have to climb the tree just to get the sloth. But in my opinion

tropical rainforest has higher species richness than the tropical grassland ecosystem. However‚ when based in the indices on Diversity‚ Similarity and Dominance in the tropical grassland and tropical rainforest data‚ the Simpson Indices favor the data for the tropical rainforest as more diverse than the tropical grassland. The Simpson Indices‚ as defined in Cuevas et. al (2012)‚ is based on dominance and as the number of dominant species in a community are few‚ the species has low diversity. The tropical

Most people "donate" money not because pandas are useful or important‚ the main reason is they are pretty. Exactly! Other species like rhinos and otters can extinct too‚ moreover they have more important role in the ecosystem. People do not let predators eat pandas as there’s only some left and as they eat only bamboo‚ we can assume that pandas have no place in a food chain

for their heads to say you killed one seems inhumane. Trophy hunting is unacceptable for several reasons. According to a 2015 Business Insider article‚ about 70‚000 animals are killed each year by trophy hunters‚ and most of the animals are either endangered‚ threatened‚ or near-threatened. Trophy hunters say that they will pay up to two million dollars a year to hunt‚ and that the money goes to help the local communities. Only 3 percent of the money goes to the local communities. 3 percent of 2 million

coral reef being home to one-third of fish species‚ humans have severely impacted the fish species by destroying their homes. Overexploitation is a huge risk‚ and this became very evident when the wolf population in Yellowstone was wiped out. Every wolf was hunted and killed in Yellowstone‚ and once the wolves were gone‚ the ecosystem became very unbalanced and many species started to either die out or be overpopulated. As for methods to help sustain species‚ core reserves and wildlife corridors are

There must be similarities that scientists have agreed upon if they have decided that they would group them. We places species of similar body or bone structures near each other in their organization. These are perceived connections‚ regardless of our perspective on the origination of these species.
