Drosera rotundifolia is an insectivorous plant that occurs in marshes, bogs and fens in a circumboreal distribution; common names for this species are Roundleaf Sundew or...
GrassesLast Updated on 2013-12-12 14:43:37
The grass family Poaceae (also known as Gramineae) contains approximately 10,000 distinct species and 650 to 900 genera. Only the sunflower (Asteraceae, or Compositae), legume (Fabaceae, or Leguminosae), and orchid (Orchidaceae) families are larger in terms of number of taxa. The grass family has more individual plants and a wider environmental range than does any other family, occupying the geographic limits of vegetation in polar regions and on mountaintops, enduring extremes of cold, sunlight, heat, and drought, while dominating various landscapes worldwide. Grasses are the most successful monocots (seed-bearing plants with single seed leaves), and the most beneficial plants for humankind, providing highly nutritional grains and livestock forage, and preventing soil erosion. Of the five crops that provide almost two-thirds of the food caloric intake that mankind consumes,... More »
Florida Black BearLast Updated on 2013-10-29 16:30:17When the American black bear (Ursus americanus) in Florida was first scientifically described in 1896 by naturalist C. Hart Merriam, he thought its long skull and highly arched nasal bones distinguished it from black bears in other areas and classified it as a separate species (Ursus floridanus), which he called the Everglades bear. Subsequent analyses around 1960 revised the status of these bears to the Florida black bear (U. a. floridanus), one of 16 recognized subspecies .
Species:-- Ursus americanus Pallas, 1780

HerbivoreLast Updated on 2013-10-24 16:24:24A herbivore is an animal that obtains its energy and nutrients by feeding on plants. Different types of herbivores eat different plant parts. For example, folivores feed on leaves, frugivores feed on fruits, granivores feed on seeds, pollinivores feed on pollen, and nectarivores feed on nectar. Herbivores can vary greatly in size, ranging from the largest terrestrial animals (elephants) and large marine mammals such as manatees and dugongs to small insects, nematodes and thrips. Herbivores are primary consumers (they receive their energy by consuming primary producers), so they play an important trophic role in ecological communities and food webs.
Because mature leaves are low in nutrients, and difficult to digest because of their high cellulose content, animals use many different strategies to eat leaves. Animals that feed on grass leaves are generally... More »
CubozoaLast Updated on 2013-10-23 13:31:26Cubozoans are astounding animals. They resemble basic jellyfish, but they can swim quite rapidly, maneuver with great agility, and have good vision despite not having a brain...Believe it or not!
In general, box jellies are similar in form to the "true" jellyfish, known as scyphozoans. However, it is relatively easy to tell the two groups apart. Cubozoans have a square shape when viewed from above. (Gee, maybe that's how they got their name.) They also have four evenly spaced out tentacles or bunches of tentacles and well-developed eyes. Not surprisingly, given their squishy nature, there are not many fossil cubozoans known. Today, there are about 20 known species found in tropical and semitropical waters. The Australian stinger Chironex fleckeri is among the deadliest creatures in the world, having caused human fatalities.
Cubozoans are rare as fossils. A... More »
Bornean Clouded LeopardLast Updated on 2013-09-30 23:00:04The Bornean clouded leopard (Neofelis diardi), or Sundaland clouded leopard, is a medium-sized wildcat found on Borneo, Sumatra and the Batu Islands in the Malay Archipelago Its coat is marked with irregularly-shaped, dark-edged ovals which are said to be shaped like clouds, hence its common name. Though scientists have known of its existence since the early 19th century, it was positively identified as being a distinct species in its own right in 2006, having long been believed to be a subspecies of the mainland Clouded Leopard (Neofelis nebulosa). WWF quoted Dr. Stephen O'Brien of the U.S. National Cancer Institute as saying, "Genetic research results clearly indicate that the clouded leopard of Borneo should be considered a separate species".
