Save the Jaguar


Description


                                                                                                                                                                   The jaguar (Panthera onca) is the largest cat of the Americas and a formidable predator. Its common name comes from the native Indian name ‘yaguara’, meaning ‘a beast that kills its prey with one bound, and its power is clearly displayed by its muscular build, deep chest, large head, broad muzzle, and strong jaws. This remarkable cat possesses a visually striking coat of large black rosettes, mostly enclosing dark spots, set against golden brown to yellow fur, which pales to white on the cheeks, throat and underside. Melanistic forms are also relatively common, often called ‘black panthers’ in the Americas. Jaguars vary considerably in size in different regions, but genetic studies indicate that there are no subspecies . Jaguars found in the dense forested areas of the Amazon Basin are generally smallFier and darker in colour than those found in more open terrain.

Habitat

The jaguar is found in a variety of habitats across its range, from dense rainforest to seasonally flooded swamp areas, scrubland and savannas, but always near water. Primarily occupying lowlands of below 1,000 metres, sightings of jaguars have been reported as high as 3,800 metres.

Status.                                          

The jaguar is classified as Near Threatened (NT) on the IUCN Red List (1), and listed under Appendix I of CITES (1).
IUCN Red List species status – Near Threatened

Threats

Sadly, human activities have generated the principle threat to the survival of the jaguar. Commercial hunting for their pelts was responsible for the death of 18,000 jaguars a year in the 1960s and 1970s. Fortunately, this toll has declined dramatically since the mid-1970s as a result of anti-fur campaigns and CITES controls, which progressively shut down international markets. Due to their predation on domestic livestock, the killing of jaguars by cattle-ranchers is also an ongoing problem. One of the primary threats today comes from deforestation, which is having a drastic impact on the jaguar’s prey base, as well as fragmenting the cat’s population into more isolated pockets, making them more vulnerable to the predations of man.

HABITAT:
Its  habitat is like a tent all covered with ice and it is on the top of the mountain.


STATUS
It is classified as least concern.


THREATS

The threats are global warming and another is that they catch this

Save the Dyeing Poison Frog

Hi everyone! Let me talk about the Dyeing Poison Frog. Look the description         


Often said to be the most alluring of all frog species, the dying poison frog (Dendrobates tinctorius) has bright colouration that is thought to function as a warning to predators that it is poisonous. The dyeing poison frog is often royal blue, fading into an attractive sky blue background, peppered with both large and small black spots. Its underside is similarly patterned, and may also sport a darker stripe down the centre. 


This incredible animal has to face some threats...Look at them!


        Population numbers of the dyeing poison frog are now relatively stable. However, this species previously suffered due to over-collection for the pet trade, and although it breeds easily in captivity, illegal collection may still continue. Habitat loss due to destruction of its rain forest habitat is also a potential threat to the dyeing poison frog

Antarctic Krill

  1. ANTARCTIC KRILL                                                                                                 By:Regina

Description

One of the most abundant organisms in Antarctic waters, the Antarctic krill is a ‘keystone species’ of the Southern Ocean ecosystem, playing a crucial role within the food chain as the main prey for a wide variety of predators, including fish, penguins, seals and whales . A small crustacean which is relatively shrimp-like in appearance, the Antarctic krill has a hard, calcified exoskeleton which is divided into three sections: the head and the thorax (which are fused into what is known as the cephalothorax), and the abdomen. Each section is further divided up into individual segments, with many of the...

Habitat

  • The Antarctic krill inhabits a variety of habitats throughout its life cycle, with adults more often associated with deeper waters, especially during winter, while juveniles are usually found at the surface of inshore waters, beneath the sea ice. The Antarctic krill is also commonly found in dense aggregations, where surface currents bring together many individuals to form patches or swarms, although groups are capable of migrating up and down the water column. These large groupings can span from a few square metres to more than 100 square kilometres, and are most often associated with islands, continental shelves and slopes, and zones of mixing water.

    Status

    This species has yet to be classified by the IUCN

    Threats

    Although the Antarctic krill population is currently estimated to have an incredible total mass of between 100 and 500 million tonnes, over the last 30 years the abundance of krill has seriously declined . Several threats to Antarctic krill have been identified, including increasing commercial demand for krill oil and meal for the aquaculture, medical and cosmetic industries, as well as advancing technologies which enable much greater catches and quicker processing. Over recent years, the Antarctic region has also seen significant increases in temperature as a result of climate change, which is affecting the extent and duration of the winter sea ice on which successful krill reproduction is so dependent.
    An additional concern is that Antarctic krill is the main food source for many predators, which are increasingly having to compete with fisheries that target krill aggregations on island shelves close to breeding sites. Over-fishing of these vital food sources will alter the whole Antarctic ecosystem, with localised depletions likely to have a severe knock-on effect for many predator populations

Flatback turtle




Flatback turtle (Natator depressus)

Description

One of just seven species of sea turtle, the flatback turtle is distinguished by its restricted distribution and its very flat carapace, or upper shell. The fleshy carapace, which is composed of thin, bony scales, has an upwards turned rim, particularly towards the rear. The carapace may be grey, pale grey-green or olive in colour. The head and soft flippers are also olive-grey, while the underside is pale yellow. Flatback turtle hatchlings are olive-green with scales edged in black.

Range

Having one of the most restricted ranges of any marine turtle, the flatback turtle is found only in the tropical waters of northern Australia, Papua New Guinea and Irian Jaya, and nests only in Australia.

Habitat

The flatback turtle inhabits coastal waters over soft-bottomed sea beds. Like other marine turtles, its lays its eggs on sandy beaches, either on the Australian mainland or on offshore islands.

Status

Classified as Data Deficient (DD) on the IUCN Red List 2007 (1), and listed on Appendix I of CITES (4) and Appendix II of CMS (5).
IUCN Red List species status – Data Deficient





Threats

There is a large range of threats which may be affecting populations of the flatback turtle. Flatback turtle eggs and hatchlings are threatened by tourism and recreation disturbing nesting beaches, the effects of light pollution, and harvesting by indigenous people. They are also vulnerable to predation by feral pigs, particularly on the Cape York Peninsula. Adult flatback turtles are harvested for their meat, and face additional threats such as entanglement in lost or discarded fishing nets, ingestion of marine debris, being struck by boats, and being caught as by-catch. Flatback turtles comprise the majority of the turtleby-catch (59 per cent) in trawls in the Northern Prawn Fishery (8). However, as one of the most poorly understood marine turtle species, there is insufficient information to determine to what extent the flatback turtle may be affected by these threats, and thus it has been classified as Data Deficient on the IUCN Red List (1).

THE EMPEROR PENGUIN

DESCRIPTION


Standing over a metre in height and weighing up to 40 kilograms, the emperor penguin  is the undisputed heavyweight of the penguin world . Slow and dignified, the emperor penguin is a stunning bird with a blue-grey back that shades into a black tail, and a characteristically white belly flushed with yellow. Deep yellow ear patches on either side of the head fade down the neck and the upper chest, while the remainder of the head and throat is black .

THREATS:

As a result of a projected rapid population decline, in 2012 the emperor penguin was uplisted to Near Threatened on the IUCN Red List . Sadly, climate change models predict a colossal reduction in the extent of the Antarctic sea-ice, which would result in the loss of large areas of emperor penguin breeding habitat. Based on climate change models, recent research indicates this species could decline by as much as 95 percent 

HABITAT

The breeding colonies of the emperor penguin are mainly found on level areas of stable sea-ice. These may be close to the coast or up to 18 kilometres offshore, and are often sheltered sites in the lee of ice-cliffs, hills or bergs
