LichenLast Updated on 2014-08-28 00:58:22
The lichen has traditionally been referred to as a prime example of a symbiotic relationship. Each lichen consists of an intimate association between a fungus and a species of algae. The algae within the lichen photosynthesizes, providing food for both symbionts. The fungus protects the alga from harmful light intensities, produces a substance that accelerates photosynthesis in the algae, and absorbs and retains water and minerals for both organisms. There is physiological and ultrastructural evidence that suggests the fungus parasitizes the algae in a controlled fashion and, in some instances, actually destroys the algal cells. There are about 25,000 species of lichens known and they are capable of living in environmental conditions that kill most other forms of life. The number of aquatic lichens is limited as most live under the blazing sun often on bare rocks. Aquatic... More »
AngiospermLast Updated on 2014-08-25 13:09:22
The Angiosperms, or flowering plants, described taxonomically as the division Magnoliophyta, are the largest grouping within the plant kingdom (Kingdom ''Plantae'' or "Viridiplantae") in terms of the numbers of described species. Approximately 260,000 species of flowering plant have been named so far -- constituting nearly 90% of all known species of plants. Even so, taxonomists describe many new species annually, and estimates of total angiosperm diversity reach as high as 400,000 species. There are about 450 families of flowering plants, and they display extremely diverse life-histories and ecological adaptations. In addition to dominating plant biodiversity, angiosperms are the dominant photosynthesis/photosynthetic organisms (primary producers) in most terrestrial ecosystems (an important exception to this rule are the boreal forests,...

CactusLast Updated on 2014-08-20 18:54:05Cactus is a family of plants that are specially adapted to survive arid conditions, most often having leaves reduced to spines, and succulent characteristics. The scientific family name Cactaceae is applied to this group comprising 121 different genera. This plant family is concentrated in the Americas and has a surprisingly broad latitude range in both the Northern and Southern Hemispheres.
A considerable number of cacti species are threatened, chiefly due to habitat loss to agriculture, trampling by illegal human immigration into the southwestern USA, large-scale desert solar power projects, and overcollecting.
The cactus family is generally considered native to the Americas. A notable exception is Mistletoe cactus, Rhipsalis baccifera, which is thought to have spread, fairly recently, from the American tropics to the subtropics and the deserts of the... More »
PinnipedLast Updated on 2014-07-21 17:04:25Pinnipeds ("finned-feet") are are group of marine mammals, that includes seals, sea lions, and walruses. The word pinniped is sometimes treated as a synonym for "seal" since all pinnipeds except for the the sole species of Walrus are seals (sea lions are eared seals).
Kingdom: Animalia (Animals)
Class:------ Mammalia (Mammals)
Order:-------- Carnivora (Carnivores)
Family:-------- Otariidae (Eared seals)
Pinnipeds differ form other marine mammals like whales, dolphins and porpoises in that they do not spend their entire lives in water. Pinnipeds "haul out" onto land and ice to mate, give birth, moult, and rest.
Pinnipeds were agressively hunted until the early twentieth century for their skins, oil, meat and, in the case of... More »
