Chapter 6 Outline I. Population Dynamics and Carrying Capacity * Populations change in size‚ density‚ and age distribution; most members of populations live together in clumps or groups. * Three general patterns in a habitat: clumping‚ uniform distribution‚ and random dispersion. Most live in clumps or groups. * Availability of resources varies from place to place. * Living in groups offers better protection from predators. * Some predator species live in

The Asiatic lion (Panthera leo persica)‚ also known as the Indian lion‚ is a lion subspecies that exists as a single isolated population in India’s Gujarat State. It is listed as Endangered by IUCN based on the small population size.[1] The lion population has steadily increased in Gir Forest National Park‚ more than doubling from a low of 180 individuals in 1974 to a level of 411 individuals consisting of 97 adult males‚ 162 adult females‚ 75 sub-adults‚ and 77 cubs as of April 2010.[3] The Asiatic

wild. Given that it’s rare for adult orangutans‚ supremely adapted to life in trees‚ to ever touch the ground; it’s no wonder that forest degradation‚ fragmentation and outright clearing—sometimes by intentionally set fires—are the main drivers of the species’ population decline. The result has been the loss of some 80 percent of the orangutans’ habitat in just the last two decades. While small independent farmers are cutting down rainforest swaths to plant their crops‚ an even larger problem is

are chemoheterotrophic and obtain energy from chemical reactions and nutrients from preformed organic matter. Most species are saprobes‚ and some are parasites. Reproduction in algae occurs in both asexual and sexual forms. Asexual reproduction occurs through the fragmentation of colonial and filamentous algae or by spore formation (as in fungi). Spore formation takes place by mitosis. Binary fission also takes place (as in bacteria). During sexual reproduction‚ algae form differentiated sex cells that fuse to produce

Each forest type forms a habitat for a specific community of animals that are adapted to live in it.The term forest implies ‘natural vegetation’ of the area‚ existing from thousands of years and supporting a variety of biodiversity‚ forming a complex ecosystem.
