    Dragged to extinction by dogs and cats

    The thylacine -a marsupial- was once prevalent across Australia and Tasmania. Today it seems that domestic dogs and other introduced animals have outcompeted the species. It was also persecuted by farmers and is now extinct, although there are continued reports of sightings but all are inauthentic.

    Canine distemper virus wildlife mortal enemy

    Diseases are parts of life, but in a well-balanced ecosystem virulent epidemics are rare. Disease can even be beneficial to a population, weeding out old or weak animals. Problems occur when a population of animals is exposed to a new disease to which it has not had a chance to build up natural immunity.

    Wolves’ precarious future in Iran

    Over the last two weeks, two children from Zanjan Province were attacked by wolves. On 13 May one of these wolves was shot dead. This is the sad story of wolves in Iran. Wherever wolves come into contact with people, the animals are regarded as dangerous pests who will- given the chance- kill people and livestock. They are poisoned, trapped and shot not only for their conviction, but also for human fear.

    Mugger crocodile as a wild beast

    The beautiful broad-snouted Crocodile kept at Tehran Zoo is a vulnerable species and also known as Mugger. The snout of this Mugger has expanded, this head-on view allows the crocodile to grasp its prey without getting any attention. Drought and also habitat destruction led to their population decline. Some individuals survive today primarily in captivity. Lack of awareness about their place in the web of life were pushed species such as Muggers to the brink of extinction.

    Birds of prey: Egyptian vulture

    Including some of Iran’s biggest birds, the vultures soar high up, using superb eyesight to spot potential food on the ground: they eat meat, preferably freshly dead animals. They need warm, rising air or up-draughts and live in mountainous areas. Vultures, such as Egyptian Vulture, have very long wings, soaring on warm air with little expenditure of energy.

    Why some species are kept in zoos?

    Many questions arise concerning keeping animals in the zoos around the world. Richard Primack B. Primack in the book of “A primer of conservation biology” page 200 of chapter 6 wrote: “Zoos, along with affiliated universities, government wildlife departments, and conservation organizations, presently maintain 500,000 terrestrial vertebrate individuals, representing almost 8000 species and subspecies of mammals, birds, reptiles, and amphibians." But there are some protests here in Iran against the presence of species such as Persian squirrel, brown bear and also birds such as flamingos in the zoos. What is the reason for this?

    Introduced species, species living outside its native distributional range arrived there by human activity, either deliberate or accidental, are responsible for about 40% of historic extinctions. Most of these data come from mammals and birds for which there is more information.

    The importance of common fox in Iran

    The ecology of the common fox is of interest because of high adaptability. This species is found in all regions of Iran with the exception of the northern forests and the drier parts of the central deserts, where it is replaced by the sand fox. In Europe common fox (or red fox) is a reddish color but in Iran it is usually a buff grey-brown with a browner back. In North America, however, there are many distinct color varieties, with up to 20 percent of red foxes being black or silver.

    Lands covered temporarily or permanently by water (except for lakes, reservoirs, and streams) and located away from coastal areas are called inland wetlands. They include marshes, prairie potholes (depressions carved out by glaciers), swamps (dominated by trees and shrubs), mud flats, flood-plains, bogs (rain-fed, peat-rich areas), wet meadows, and the wet arctic tundra in summer. Some wetlands are huge, others are small.

    Each known species on the Earth has a specific name which is called the “scientific name” of that species. Scientific names normally have two parts and in some cases, three. These names are considered as common points which allow scientists or even public throughout the world to talk precisely about their determined species of plants or animals.
