Canada's Chinook Salmon Endangered

Canada’s Chinook Salmon Endangered

Half of Canada’s Chinook salmon are endangered, with nearly all other populations in precarious decline, according to a new report, confirming fears that prospects for the species remain dire. The report by the Committee on the Status of Endangered Wildlife in Canada concluded that eight of the country’s 16 populations are

The vast majority of the world’s largest species are being pushed towards extinction, with the killing of the heftiest animals for meat and body parts the leading cause of decline, according to a new study. While habitat loss, pollution and other threats pose a significant menace to large species, also known as megafauna, intentional and unintentional trapping, poaching and slaughter is the single biggest factor in their decline, researchers found. An analysis of 362 megafauna species found that 70% of them are in decline, with 59% classed as threatened by the International Union for Conservation of Nature. Direct killing by humans is the leading cause across all classes of animals, the study states. A range of maladies, including intensive agriculture, toxins and invasive competitors are also helping to trigger these declines. This situation adds to the “mounting evidence that humans are poised to cause a sixth mass extinction event,” according to the research, published in Conservation Letters. It adds that “minimizing the direct killing of the world’s largest vertebrates is a priority conservation strategy that might save many of these iconic species and the functions and services they provide.”

Sturgeon

Sturgeon

Sturgeon is the common name for the 27 species of fish belonging to the family Acipenseridae. Their evolution dates back to the Triassic some 245 to 208 million years ago. The family is grouped into four genera: Acipenser, Hugo, Scaphirhynchus and Pseudoscaphirhynchus. Four species may now be extinct. Two closely related species, Polyodon spathula (American paddlefish) and Psephurus gladius (Chinese

Tardigrade

Tardigrades, also known colloquially as water bears, or moss piglets are a phylum of water-dwelling,eight-legged, segmented micro-animals. They were first described by the German zoologist Johann August Ephraim Goeze in 1773, who gave them the name of “little water bears.” The name Tardigrada (meaning”slow steppers”) was given three years later by the Italian biologist Lazzaro Spallanzani. They

The Bush Viper

The Bush Viper

Atheris is a genus of venomous vipers known as bush vipers. They are found only in tropical Sub-Saharan Africa (excluding southern Africa) and many species have isolated and fragmented distributions due to their confinement to rain forests. In an example of convergent evolution, they show many similarities to the arboreal pit vipers of Asia and South America. Sixteen species are currently recognized. They are relatively small in size, with adults

The Red Panda

The Red Panda

The red panda (Ailurus fulgens), also called the lesser panda, is a mammal native to the eastern Himalayas and southwestern China. It has reddish-brown fur, a long, shaggy tail, and a waddling gait due to its shorter front legs; it is roughly the size of a domestic cat, though with a longer body and somewhat heavier. It is arboreal, feeds mainly on bamboo, but

Marvels Of The Deep And Their Superpowers

A hydrothermal vent is a fissure in a planet’s surface from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart at spreading centres, ocean basins, and hotspots. Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within

Poached For Its Horn, This Rare Bird Struggles To Survive

The helmeted hornbill (Rhinoplax vigil) is a very large bird in the hornbill family. It is found on the Malay Peninsula, Sumatra and Borneo. The casque (helmetlike structure on the head) accounts for some 11% of its 3 kg weight. Unlike any other hornbill, the casque is almost solid and is used in head-to-head combat among males. It has mostly blackish
