Excerpt: The Egyptian cobra (Naja haje) is a venomous snake found in Africa and the Arabian Peninsula. The Egyptian cobra may grow to between 5 and 8 feet (1.5 and 2.4 m) in length and specimens as long as 8 feet (2.4 m) have been seen in some areas. The most recognizable characteristics of an Egyptian cobra are its head and hood. The head is large and depressed with a broad snout. The cobra's eyes are large with a round pupil. Its neck may range from 15 to 18 centimetres (5.9 to 7.1 in) wide. The colour is variable, but most specimens are some shade of brown, often with lighter or darker mottling, and often a "tear-drop" mark below the eye. Specimens from northwestern Africa (Morocco, Western Sahara) are almost entirely black. The Egyptian cobra typically makes its home in dry to moist savanna and semi-desert regions with at least some water and vegetation (never in desert regions). The cobra may also be found in oases, agricultural grounds, hills with sparse vegetation, and grasslands. These cobras are not afraid of humans and often enter houses. They are attracted to the human villages by chickens and rats that are attracted by garbage. There are also reports of Egyptian cobras swimming in the Mediterranean sea. The Egyptian cobra is terrestrial and nocturnal in the wild, though in captivity they seem to tend towards diurnality. It can, however, be seen basking in the sun at times in the early morning. It shows a preference for a permanent home in abandoned animal burrows, termite mounds or rock outcrops and the like, sometimes entering human habitations to hunt domestic fowl. It will general...More: http://booksllc.net/?id=14572625 ... Read more

Excerpt: A cobra (·)) is a venomous snake belonging to the family elapidae. The name is short for cobra de capelo, which is Portuguese for "snake with hood", or "hood-snake". When disturbed, most of these snakes can rear up and spread their neck (or hood) in a characteristic threat display. However, not all snakes referred to as cobras are of the same genus, or even of the same family. Cobra may refer to: ...More: http://booksllc.net/?id=226928 ... Read more

Description:
In 1999, we published a report on how an introduction of 20 males into a severely inbred and isolated population of adders (Vipera berus) halted its decline towards extinction, induced a profound change in population genetic variability, resulted in a dramatic increase in offspring viability and thus in a rapid increase in numbers. Since the publication of our paper we have received numerous inquiries as to whether we have continued to monitor this population, as this is the case we herein present population demographic data gathered between 1981 and 2003. The population has continued to increase in numbers and in 2003, we collected 39 adult male adders, more than at any time over the 23-year study. Our continued work, hence, lends strong support to the importance of novel genes in enhancing the viability of inbred populations and supports the importance of preserving genetic variability in order to maintain viable wild populations. ...
