Featured Article: Hyrax

Hyrax
Hyrax is the common name for any of the largely herbivorous mammals comprising the order Hyracoidea, whose modern members are characterized by thickset bodies, short tails, and three-toed hind feet with rounded, hoof-like nails on two of the toes and a claw on the third. These mammals, which can be described as having a guinea pig or woodchuck-like body, and are similar in size to a large rabbit, are also known as cories and dassies. The presence of specialized muscles in the soles of the feet, combined with the soft and elastic nature of the sweat-gland moistened soles, helps to create a suction-like friction with rocks and other substrate, making them agile climbers.

There is one extant family of hyraxes, Procaviidae, distributed only in Africa and the Middle East. Hyraxes are often mistaken for rodents, but are more closely related to elephants.

In the book of Leviticus in the Bible (Lev. 11:5), some translations list the hyrax as one of the animals that is forbidden to be eaten.

Popular Article: Ecology

The Earth seen from Apollo 17
Ecology or ecological science, is the scientific study of the distribution and abundance of living organisms and how these properties are affected by interactions between the organisms and their environment. The environment of an organism includes both the physical properties, which can be described as the sum of local abiotic factors like climate and geology, as well as the other organisms that share its habitat.

Ecology may be more simply defined as the relationship between living organisms and their abiotic and biotic environment or as "the study of the structure and function of nature" (Odum 1971). In this later case, structure includes the distribution patterns and abundance of organisms, and function includes the interactions of populations, including competition, predation, symbiosis, and nutrient and energy cycles.
