Conservation Biology

Conservation biology addresses the preservation of species and their habitats throughout the world. Techniques used in these endeavors include genetics, vegetation restoration, wildlife management and other natural resource management activities. During the last 10,000 years, species extinctions have been occurring at an alarming rate, due to the human population explosion, and resulting habitat destruction for agriculture and other human purposes. The importance of conservation biology is underscored by the fact that an estimated 1800 populations per hour are being lost at the present pace of ecological damage. Conservation biology seeks to maintain populations of plants and animals, with an emphasis upon rare and endangered species. 

An intrinsic part of conservation biology is identification of species interactions, in order to understand the core elements of preserving an intact habitat in its full functionality.  Equally important is an understanding of genetic diversity within each species and the population dynamics that underlies the progression of species numbers from one generation to the next. Conservation biology is practiced by governmental agencies, but also by private organizations, since key element of land ownership are often privately owned; coordination of a regional strategy among landowners is vital for the preservation of biological corridors. Captive breeding programs are used as a defense of last resort in the preservation of a species.

Highveld grasslands Last Updated on 2015-07-07 21:46:02 WWF Terrestrial Ecoregions Collection Highveld grasslands ecoregion covers a large portion of west-central South Africa. Grasslands all over the world have experienced dramatic habitat destruction as a result of anthropogenic changes. The Highveld grasslands are no exception, with agriculture severely fragmenting this once-expansive region. This ecoregion now provides the last remaining stronghold of a number of grassland species that have suffered major reductions in abundance in the grassland biome, and which are consequently threatened with extinction (e.g. the Blue Crane (Anthropoides paradisea). There is a relatively biodiverse vertebrate fauna, with 608 taxa recorded. This ecoregion is part of the Montane Grasslands and Shrublands biome, within the Afrotropics Realm. The ecoregion draws its name from the high interior plateau known as... More »
Habitat fragmentation Last Updated on 2015-07-04 14:10:43 Habitat fragmentation involves alteration of habitat resulting in spatial separation of habitat units from a previous state of greater continuity. Figure 1. Aerial photograph of dry forest scrub in southern Zambia, fragmented by agricultural land conversion. 2008. Source: C.Michael Hogan This phenomenon occurs naturally on a geologic time-scale or in unusual and catastrophic events: however, since the Holocene era, humans have produced dramatic and swift transformation of landscapes throughout the world, resulting in a level of habitat fragmentation that has induced worldwide reduction in biodiversity and interuption of  sustainable yields of natural resources. Humans produce habitat fragmentation chiefly from agricultural land conversion, urbanization, pollution, deforestation and introduction of alien species; ironically, both human caused... More »
Nama Karoo Last Updated on 2015-07-02 23:56:32 WWF Terrestrial Ecoregions Collection The Nama Karoo is a vast, open, arid ecoregion in southern Africa dominated by low-shrub vegetation, punctuated by rugged relief. Although not remarkably rich in species or endemism, the flora and fauna of the region are impressively adapted to its climatic extremes. The Nama Karoo ecoregion is part of the Deserts and Xeric Shrublands biome, within the Afrotropics Realm. The major threats to biodiversity are posed by pastoralism, introduction of alien species of plants, mining and conversion of native habitat to agriculture, all exacerbated by the fact that very little - less than one percent - of the ecoregion is conserved. Most of the Nama Karoo occurs on the central plateau of the Cape Province in South Africa, although it extends over the Orange River into Namibia in the northwest. The Great... More »
Madagascar succulent woodlands Last Updated on 2015-07-01 18:43:46 WWF Terrestrial Ecoregions Collection The Madagascar succulent woodlands ecoregion comprises a mosaic of succulent xeric adapted plants and deciduous forests that represent critical habitats for many species of animals and plants restricted to the western region of Madagascar. Some of the remarkable fauna and flora found in this ecoregion include the Giant jumping rat (Hypogeomys antimena), the Flat-tailed tortoise (Pyxis planicauda), two species of baobabs and several species of primates. The Madagascar succulent woodlands is classified within the Desert and Xeric Shrublands Biome, and is part of the Afrotropics Realm. These succulent woodlands are situated in southwestern Madagascar extending northward to the central western part of the island. Its southern limit is the start of the Madagascar spiny thicket and northern limit the lower... More »
Madagascar spiny thickets Last Updated on 2015-06-25 20:16:56 WWF Terrestrial Ecoregions Collection The Madagascar spiny thickets or spiny desert of southern Madagascar, also referred to as deciduous thicket, is a globally distinctive ecoregion. This ecoregion is part of the Deserts and Xeric Shrublands biome, within the Afrotropics Realm. While the island of Madagascar is notable for exceptional levels of endemic plants and animals, the spiny thicket is particularly distinctive with 95 percent of the plant species endemic to the ecoregion. Members of the endemic Didiereaceae family present dominate the thicket, which have similar xeric adaptations to New World cacti, such as small leaves and spines, but with the Madagascar spiny thickets displaying more woody rather than succulent characteristics. There are a total of 288 recorded vertebrate taxa in the Madagascar spiny thickets, including several endemic... More »
