Traditionally, the term wildlife has conjured images of species which are of economic or emotional importance to humans. However wildlife life encompasses a much broader array of life on earth, referring to any undomesticated species, from the European Fire-bellied toad to the Siberian tiger.
As humans have encroached on the natural habitats of the world's wildlife, contaminated the far reaches of earth and hunted or fished some species to extinction, understanding qualities like habitat requirements, lifecycles and nutritional needs for all wildlife species has become a primary focus of many scientists and conservationists.
For many species, their survival depends upon our ability to identify the basic needs for wildlife populations to survive and thrive and act upon that knowledge.
The Indus River dolphin (scientific name: Platanista minor) is fresh water cetacean closely related to the Ganges River dolphin (Platanista gangetica). These two endangered...
Etosha Pan halophyticsLast Updated on 2014-12-26 13:11:38
WWF Terrestrial Ecoregions Collection
The Etosha Pan Halophytics ecoregion is the relict landform of a prehistoric expansive, inland Pliocene lake. Today, the Etosha Pan is mostly an arid, saline desert. Typically, the intensively cracked, whitish clay is split into hexagonal salt-encrusted fragments, and wildlife is sustained only by scattered freshwater springs, which manifest as watering holes. These springs attract a diverse array of large mammals, especially during the dry season, making Etosha Pan a popular tourist destination. In unusually wet years, when the Ekuma, Oshigambo and Omuramba Ovambo Rivers receive sufficient rainfall, the pan is temporarily transformed into a shallow lake.
When surface water is present, it can be classified as a hypersaline lake, due to the elevated salinity. The Etosha Pan halophytics is considered within the... More »
WildlifeLast Updated on 2014-12-07 15:36:41Wildlife refers to the animals and related plants in a state of nature, or the species of fauna that are not domesticated or tame and are also indigenous to an area, region or range. The expression is relatively recent in origin dating to Richard Jefferies' 1879 work discussing the various animal species in the Wiltshire Downs in southern Britain. Jefferies insisted, “glance into the hedgerow, the copse, or stream,” and “there" you find "nature’s children as unrestrained in their wild, free life as they were in the …backwoods of primitive England.”
The term wildling is much older, however, as is wildness from which wildlife is derivative, being used for example by William Shakespeare to refer to those qualities of living things not under the influence or control of humans. Charles Darwin when referring to artificial selection... More »
Wind turbine bird mortalityLast Updated on 2014-11-30 21:32:32Wind turbine bird mortality is a by-product of large scale wind farms, which are increasingly promoted as an alternative to fossil fuel derived energy production. To adequately assess the extent of impact to avian populations, deeper factors than gross mortality by turbine action must be assessed. In particular, one must examine: (a) impacts to threatened bird species, (b) total impacts due to avian habitat loss as well as direct mechanical kill, (c) ecological impacts due to apex predator bird loss and (d) future siting decisions for windfarms, since much of the prior bird mortality is due to poor siting decisions.
Bird mortality from wind turbines is a significant adverse ecological impact, and threatens to expand in scope dramatically with the rush to develop new energy sources. This impact is measured as high due to the loss of threatened species and due to... More »
Biological corridorLast Updated on 2014-11-30 21:27:13
Biological corridor is the designation for a continuous geographic extent of habitat linking ecosystems, either spatially or functionally; such a link restores or conserves the connection between habitats that are fragmented by natural causes or human development. Such corridors are an important aspect in the preservation of species richness and biodiversity. There are different scales of biological corridors, but all share the same purpose of providing connections for species through fragmented landscapes. A biological corridor, alternatively termed habitat corridor, is used for the transportation functions of fauna and seed dispersal/propagation routes for flora and lower life forms. Specific elements of this transport for fauna include seasonal or migration movement, life cycle links, species dispersal, re-colonization of an area and movement in... More »
MammalLast Updated on 2014-10-15 22:58:09
Mammalia is a group of warm-blooded, air breathing vertebrates. With the common name mammal, each species is endowed with the characteristic of fur and three-boned middle ear; but the most remarkable element of group identity is an advanced brain element known as the neocortex, that functions as a center of complex cognition; no species except mammals have this well defined brain structure. Having pronounced inherent sexual dimorphism, the females have mammary glands capable of producing milk. There are approximately 5400 described mammalian species comprising around 1200 genera.
Mammals span a size range from the three centimeter Bumblebee Bat to the 33 meter long Blue Whale. Feeding habits vary widely among species, including carnivores and insectivores who prey on animals, to frugivores and granivores who eat fruit or seeds. Earliest mammals arose approximately 200 to 130... More »
