Animal Robots being used for the Study of Animal behavior (VIDEOS)

 

As reading fiction can challenge us to better understand the fact, using fake animals can sometimes serve as our best solution to understanding the behavior of real animals. The use of dummies, doppelgangers, fakes, and physical models have served to elicit behaviors in animal experiments since the early history of behavior studies, and, more recently, robotic animals have been employed by researchers to further coax behaviors from their study subjects. 

The túngara frog (Physalaemus pustulosus) has been a study subject for investigating multimodal signalling (1). Multimodal signalling in animal behavior is when animals communicate with each other by using signals from different sensory modalities (2), like chemical odours, visual cues, auditory signals, etc

Top Ten Most Endangered Animal Species 2018

 For some species, time on our planet Earth is running out.

Human beings are the greatest threat to the survival of endangered species through poaching, habitat destruction, and the effects of climate change.

1. Amur Leopard

It inhabits in Russian. Since 1996, the amur leopard has been classified by the IUCN as Critically Endangered with less than 70 individuals 

thought 

to exist today. It is hunted and killed for its beautiful fur. Its habitat is 

being 

destroyed for human settlement and agricultural practices.

It is one of the rarest felines in the world. They are speedy creatures able to run up to 35 miles per hour, faster than Usain Bolt!

2. Gorillas

Cross River Gorillas and Mountain Gorillas are both classified as Critically Endangered and Endangered by the IUCN since 1996 – that is two out of five gorilla subspecies. There are currently only 200-300 Cross River Gorillas left in the wild, and 900 Mountain Gorillas.

3. Sea turtles
Two types of sea turtles are amongst the most endangered species in the world: the Hawksbill Turtle and the Leatherback Turtle.
In the past 100 years, the Hawksbill Turtle has lost 90 percent of its population, 80 percent of which has been lost in the past 10 years. As of 1996, the IUCN classified it as a critically endangered species. The Leatherback turtle is listed by the IUCN as Vulnerable, yet many subpopulations are facing extinction.

4. Orangutan

Since the millennium, the Sumatran Orangutan has been classified by the IUCN as Critically Endangered with approximately 80% of the population lost in the past 75 years mainly as a result of mass deforestation. This awful trend continues to put pressure on the remaining population of 6,600 Sumatran Orangutans that are estimated to remain on this earth.

5. Sumatran Elephant

In the past 25 years, the Sumatran Elephant has lost an astounding 70% of its habitat to deforestation for palm oil plantations, agriculture and human settlements. Less than 2000 are estimated to exist and in 2011, the Sumatran Elephant was classified by the IUCN as Critically Endangered.

6. Saola

In 1992, the discovery of this mystical creature, sometimes referred to as the Asian Unicorn, in Vietnam was hailed one of the most spectacular zoological discoveries of the 20th century. Yet already, this elusive and beautiful animal been deemed by the IUCN to be Critically Endangered and is one of the rarest large mammals to exist on Planet Earth.

7. Vaquita

With less than 100 thought to exist, the Vaquita is the rarest marine mammal in the world. Time is running out for these elusive little sea porpoises, with extinction predicted to become during this year or pretty soon.

8. Tiger

The tiger has long been hunted for its distinctive patterned fur. Of the nine tiger subspecies, three are already extinct, many are endangered but it is the South China Tiger and the Sumatran Tiger that currently face the biggest threat to their survival.

Tragically, the South China Tiger is thought to be extinct in the wild as it hasn’t been spotted since the 1970s. The Sumatran Tiger is the only surviving tiger subspecies indigenous to Indonesia and as of 2008 it has been classified by the IUCN as Critically Endangered. Less than 500 of these tigers exist today in comparison with a population estimation of up to 1,000 in 1978.

9. Rhinos Three of the five species in the family of Rhinocerotidae, are among the most endangered species in the world: the Black Rhino, the Javan Rhino and the Sumatran Rhino. The Javan Rhino is the most threatened with extinction with the total population of only 60 surviving in one National Park in Java, Indonesia. The Sumatran Rhino is Critically Endangered. It has been estimated that less than 100 exist today in the wild. The Black Rhino is classified by the IUCN as Critically Endangered with three subspecies declared extinct in 2011.

10. Pangolin

Despite their tough appearance, these small, warrior built mammals are losing the battle against poachers and habitat loss. All eight species of pangolin are under threat, ranging from Vulnerable to Critically Endangered. They are the most trafficked animal in the world, hunted for their scales which can be sold on the black market for up to $3,000/kg.
