The woolly mammoths range at its peak - How many Earths do we need? Image copyright Thinkstock It has been suggested that if everyone on the planet consumed as much as the average US citizen, four Earths would be needed to sustain them.

How many Earths do we need?

But where does this claim originate, and how is it calculated? The world's seven billion people consume varying amounts of the planet's resources. Compare the lifestyle of a subsistence farmer with that of a wealthy city-dweller in a developed country. More land is required to grow the city dweller's food, more materials are used to build the city dweller's home and workplace, more energy is required for transport, heating and cooling. So it's obvious that Americans consume more, on average, than the people of less developed countries.

It has been recurring on social media at least since 2012, when science writer Tim De Chant produced this infographic illustrating how much land would be required if seven billion people lived like the populations of nine selected countries from Bangladesh to the United Arab Emirates. *****Threat of cats: Invasive Mammals Are Pushing Native Birds to the Brink.

Cats Among Biggest Threats to Global Biodiversity, Study Finds Contact: Grant Sizemore, 202-888-7480 (Washington, D.C., Dec. 13, 2016) Invasive mammalian predators are killing endangered species around the world at much higher rates than previously known and are “arguably the most damaging group of alien animal species for global biodiversity,” according to a recent study published in the Proceedings of the National Academy of Sciences (PNAS).

*****Threat of cats: Invasive Mammals Are Pushing Native Birds to the Brink

The findings are the latest evidence that cats and other invasive species pose a major threat to birds and other wildlife worldwide. A recent study found cats have contributed to the extinction of 63 species worldwide. Photo by Vasily Vishnevskiy. Non-native mammalian predators have contributed to the extinction of 87 bird, 45 mammal, and 10 reptile species, and have helped put another 596 species at risk of extinction, according to the study by Dr. Vintage Style Travel Posters Invite Tourists To See Extinct Animals.

***The top 10 most biodiverse countries

Between the Amazon rainforest and Mata Atlantica forest, the woody savana-like cerrado, the massive inland swamp known as the Pantanal, and a range of other terrestrial and aquatic ecosystems, Brazil leads the world in plant and amphibian species counts. It ranks second in mammals and amphibians, third in birds, reptiles and fish. Small Countries: Pockets of Biodiversity This list focused on total biodiversity. 1764 census reveals St Kilda residents feasted on 1,600 seabirds a day. A 250-year-old census has revealed St Kilda islanders ate more than 1,600 seabirds every day.

1764 census reveals St Kilda residents feasted on 1,600 seabirds a day

The document is the earliest recorded list of the archipelago’s population and was discovered by archivists among a hoard of clan papers. The census lists 90 people living on the main island of Hirta on 15 June 1764 – 38 males and 52 females, including 19 families and nine individuals. Further light is shed on the islanders’ diet, with each resident said to eat “36 wild fouls eggs and 18 fouls” daily – an island-wide total of 3,240 eggs and 1,620 birds every day. Back to life: the world of de-extinction. Is extinction forever?

Back to life: the world of de-extinction

While most would assume that yes, extinction is the ultimate end-point, a fate from which no species can return, Chris Fitch investigates the small but growing movement that dares to disagree The passenger pigeon was a legendary species. Flying in unfathomably large numbers across North America, with potentially many millions within a single flock, their migration was once one of nature’s great spectacles.

Amazing how much difference there is in the sunlight! The worlds actual deadliest animals. 8 facts GIS has revealed about animals. Scientists have studied giraffes' physiology, but they still don’t know much about how the species as a whole operates in the wild.

8 facts GIS has revealed about animals

They don’t seem to have clear leaders, so we’re just learning how they organize into herds. We don’t know how they communicate. We don’t know why they fight. We don’t fully understand how far they will range. And scientists only recently discovered that there are not one, but four, species of giraffe – northern, southern, reticulated and Masai – each with unique genetics and spot patterns ranging from orange polygons to black blotches. Between 2011 and 2012, Namibia’s Ministry of Environment and Tourism moved more than 50 southern giraffes from Etosha National Park to three community conservancies.

[Source: Julian Fennessy, Giraffe Conservation Foundation] Dinosaurs are transported on the Hudson River to the 1964 World’s Fair. Half of the world's ecosystems are at risk. Habitat loss is the most insidious of all threats facing land-living wildlife, and protected areas like national parks are one of the best ways to combat the destruction.

Half of the world's ecosystems are at risk

But in research published recently in Conversation Letters, we show that in some places the pace of protected areas isn’t keeping up with the losses. We found that since 1992, an area of natural habitat two-thirds the size of Australia has been converted to human use (such as farms, logging or cities). Half of the world’s land area is now dominated by humans. Hyperwall: Yearly Cycle of Earth's Biosphere. Why Doubt Invasive Species Impacts? – National Geographic Society (blogs) Invasive alien species are now found on every corner of the planet and rank higher than climate change as a current threat to endangered species.

Why Doubt Invasive Species Impacts? – National Geographic Society (blogs)

So then why, despite all the scientific evidence of negative impacts from invasive species, would people be resistant to taking action against them? In two scientific papers released this week myself and colleagues have tried to understand why invasive species have such a low public profile compared to climate change, and furthermore why some elements of society would even try to deny that there is even a problem. Wait for it . . Mimosa pudica plants fold up their leaves to protect themselves when disturbed. Scientists have found that a vast underground network of fungi helps trees communicate: the “wood wide web” Peru's Manu National Park declared world's top biodiversity hotspot. Peru’s Manu National Park has claimed the distinction as the place with the greatest terrestrial species diversity compared to other emblematic areas of the world.

The park, located between the regions of Madre de Dios and Cusco, claimed the top spot based on updated information from the Red Team-Network (the Tropical Ecology Assessment and Monitoring Network). Experts came to their conclusion after analyzing about 38,000-40,000 photographs captured with the help of 60 camera traps. Cocha Cashu Biological Station and Pakitza sector in the Amazon region of Madre de Dios were the monitoring locations inside Peru’s national park. The Tropical Ecology Assessment and Monitoring (TEAM) Network monitors trends in the status of biodiversity and ecosystem services to guide conservation practices.

It analyzes the data collected from a network of field stations using standardized monitoring protocols (from the TEAM website). Earth's seasons time lapse from space.

Invasive species: “…literally thousands of weta…” The forest floor before introduced. 80-Year-Old Man Hasn’t Watered This Sealed Bottle Garden Since 1972 And It’s Still Alive. Back in 1960, David Latimer, an enthusiast, planted a seed in bottle made of glass and he never had any idea that it would bloom into an ecosystem altogether over the next few decades. Half century after he planted it, it is shocking that the plants are healthy and continue to grow despite not being watered since 1972! Decomposers: Fungi, Algae and Lichen. #RonaldLampitt. What's A Native Species? That's More Complicated Than You Might Think.

Pay attention to the natural world for any length of time at all and you’ll come up against one of the biggest divides in the life sciences: “native” species versus “introduced” species. It’s a basic concept in ecology. Ecosystems develop with certain kinds of organisms as members, and over time a predictable set of relationships develops among those organisms.
