Ancient lineages across the Drakensberg Alpine Centre and their plight for conservation. 1. Introduction: With many recent studies showing that the current global rates of biodiversity loss are cause for alarm‚ it is important to recognize regions in which biodiversity is especially high and under threat from human expansion and climate change. The combinations of biodiversity assemblages along the Escarpment form nodes of high local endemism that have contributed towards the concept of ‘centers

Introduction Camouflage‚ in other words the ability to blend in with the surroundings is a profoundly studied feature in many animals. From empirical evidence‚ animals like Chameleon and the Leaf-Tailed Gecko which have pigments that match their surroundings are much harder to spot than animals whose pigments don’t. Recent studies have shown that the bark-resting moth has a tendency to live within a habitat that has a hue similar to itself. It can alter its position on the background for a better

tropical biome monopolized by grasses‚ shrubs‚ and small trees. It’s grassland cover western India‚ northern Australia‚ South America‚ and other parts in Africa. In this biome it is very warm‚ there is little precipitation so there is not a lot of tall trees more like shrubs and bushes. A savanna is categorized between a tropical rainforest and a desert biome it is right in the middle of them. Savannas are created when humans burn grasslands and cut down trees kind of like slash and burn process to plant

Conservation is the practice of protecting plants or animals‚ and their habitats. These plants and animals may be very close to extinction. North America experienced a big loss of megafauna at the end of the Pleistocene era (about 13 000 years ago). This started a program known as “Pleistocene re-wilding”. Re-wilding involves the reintroduction of extant species into areas where they became extinct in the past. This program aims to restore the evolutionary and ecological potential that North America

Biology Assessment #4 Australian Megafauna: Thylacoleo Carnifex & Diprotodon Optatum Part A: The term Megafauna means ‘big animals’‚ and refers to animals with a body mass of over 40 kilograms. In general use‚ the term Megafauna is used to refer to the animals that evolved after the dinosaurs became extinct 65 million years ago. The extinction of the dinosaurs meant that the large number of birds‚ mammals and reptiles‚ which were left over‚ were able to evolve and dominate the earth.
