Geographic range of the bear species

Bears are large mammals belonging to the family Ursidae. They are known for their iconic appearance, typically characterized by a stocky body, a large head, and a short tail. Bears are known for their strength, and they are excellent swimmers and climbers.

Bears are generally omnivorous, although their diet can vary depending on the species and availability of food. They may feed on plants, fruits, nuts, insects, fish, and even larger mammals. Bears are typically solitary animals, although they may come together during mating season or when food is abundant.

There are eight recognized species of bears, and their distribution varies across different regions of the world. Here's a list of the eight bear species and their general geographical distribution:

  1. American black bear (Ursus americanus): The American black bear is the most common bear species in North America. They have a wide distribution, ranging from the United States and Canada to Mexico. The total population of American black bears is estimated to be over 600,000 individuals.
  2. Brown bear (Ursus arctos): Brown bears have several subspecies, including the grizzly bear in North America and the Eurasian brown bear in Europe and Asia. The total population of brown bears is difficult to estimate due to the wide range and diverse habitats they occupy, but it is believed to be around 200,000 individuals worldwide.
  3. Polar bear (Ursus maritimus): Polar bears are found in the Arctic regions of Alaska, Canada, Greenland, Norway, and Russia. They are considered a vulnerable species due to the loss of sea ice habitat caused by climate change. The estimated global population of polar bears is around 25,000 individuals.
  4. Asian black bear (Ursus thibetanus): Also known as the moon bear, the Asian black bear is found in various parts of Asia, including China, Japan, Korea, Russia, and Southeast Asia. The global population of Asian black bears is estimated to be around 25,000 individuals.
  5. Sloth bear (Melursus ursinus): The sloth bear is found in the Indian subcontinent, including India, Nepal, Bhutan, and Sri Lanka. The total population of sloth bears is estimated to be around 20,000 individuals.
  6. Sun bear (Helarctos malayanus): The sun bear is found in Southeast Asia, including countries such as Malaysia, Thailand, Indonesia, and Borneo. The population of sun bears is difficult to estimate, but it is believed to be declining due to habitat loss and hunting.
  7. Spectacled bear (Tremarctos ornatus): The spectacled bear is found in South America, primarily in the Andean regions of countries such as Peru, Bolivia, Colombia, Ecuador, and Venezuela. The global population of spectacled bears is estimated to be around 18,000 individuals.
  8. Giant panda (Ailuropoda melanoleuca): The giant panda is found in China, primarily in the mountainous regions of Sichuan, Shaanxi, and Gansu provinces. The global population of giant pandas has been recovering in recent years and is estimated to be around 1,800 individuals.

Bears species in the world

Here is the map of a geographic range of these 8 bear species.

Geographic range of different bears species

Several bear species are currently threatened with extinction or are considered vulnerable according to the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Here's a list of bear species that are considered at risk:

  1. Polar bear (Ursus maritimus): The polar bear is listed as a vulnerable species on the IUCN Red List. Climate change is the biggest threat to polar bears, as it is causing loss of sea ice, which is their primary habitat for hunting. Reduced access to food and habitat loss are major challenges for polar bears, and their populations are declining.
  2. Sun bear (Helarctos malayanus): The sun bear is listed as vulnerable on the IUCN Red List. Sun bears are threatened by habitat loss due to deforestation, illegal logging, and conversion of their natural habitat into agricultural lands. They are also hunted for their body parts and bile, which are used in traditional medicine in some regions.
  3. Sloth bear (Melursus ursinus): The sloth bear is listed as vulnerable on the IUCN Red List. Sloth bears face threats such as habitat loss, human-wildlife conflict, and poaching. They are also captured for the pet trade and used in traditional medicine in some areas.
  4. Asian black bear (Ursus thibetanus): The Asian black bear is listed as vulnerable on the IUCN Red List. Habitat loss, poaching, and illegal trade in bear parts are the main threats to Asian black bears. They are also threatened by human-wildlife conflict and fragmentation of their habitat.
  5. Spectacled bear (Tremarctos ornatus): The spectacled bear is listed as vulnerable on the IUCN Red List. The main threats to spectacled bears include habitat loss due to deforestation, hunting, and human-wildlife conflict. They are also affected by fragmentation of their habitat, which can lead to isolated populations with limited gene flow.

Conservation efforts, including habitat protection, anti-poaching measures, and community-based conservation programs, are crucial for the survival of these threatened bear species and their ecosystems.

The Appalachian Mountains, the Scottish Highlands, and the Atlas Mounts in Africa were the same mountain range

The Central Pangean Mountains was a prominent mountain ridge in the central part of the supercontinent Pangaea that extends across the continent from northeast to southwest through the Carboniferous , Permian Triassic periods. The mountains were formed due to a collision within the supercontinents Gondwana and Laurussia during the creation of Pangaea. It was comparable to the present Himalayas at its highest peak during the start of the Permian period. It isn’t easy to assume now that once upon a time that the Scottish Highlands, The Appalachian Mountains, the Ouachita Mountain Range, and the Atlas Mountains in northwestern Africa are the same mountains , once connected as the Central Pangean Mountains.

Human Emotions Visualized

Despite significant diversity in the culture around the globe, humanity's DNA is 99.9 percent alike. There are some characteristics more primary and typical to the human experience than our emotions. Of course, the large spectrum of emotions we can feel can be challenging to verbalize. That's where this splendid visualization by the Junto Institute comes in. This visualization is the newest in an ongoing attempt to categorize the full range of emotions logically. Our knowledge has come a long route since William James suggested 4 primary emotions: fear, grief, love, and rage. These kernel emotions yet form much of the basis for current frameworks. The Junto Institute's visualization above classifies 6 basic emotions: fear, anger, sadness, surprise, joy, love More nuanced descriptions begin from these 6 primary emotions, such as jealousy as a subset of anger and awe-struck as a subset of surprise. As a result, there are 102 second-and third-order emotions placed on this emo
