Check out the stunning entries in the 2022 Wiki Loves Earth photographic competition. This image, by Sven Damerow, of a cuckoo wasp, was created by blending several photos together. A larger version of the photo can be seen here.

Wiki Loves Earth was established in 2013, and initially took place in Ukraine, before becoming an international contest in 2014.



Not all work and no play as busy bumble bees play ball

31 October 2022

Researchers at London’s Queen Mary University have found bumble bees like to play, and accordingly, experience positive feelings. Despite there being no purpose to the activity, groups of bees rolled small wooden balls, sometimes repeatedly, around a chamber, for what researchers could only determine was fun.

Study first-author, Samadi Galpayage, Ph.D. student at Queen Mary University of London says that “it is certainly mind-blowing, at times amusing, to watch bumble bees show something like play. They approach and manipulate these ‘toys’ again and again. It goes to show, once more, that despite their little size and tiny brains, they are more than small robotic beings.”

This is reportedly the first instance of playful activity being observed in any insect species.

Washington, DC. based American photographer Karine Aigner has been named Wildlife Photographer of the Year for 2022, with a stunning image of male bees tussling it out to mate with a female bee.

Convened by the British Natural History Museum, the Wildlife Photographer of the Year award celebrates the best in nature photography, and is considered one of the world’s most prestigious photography competitions. A selection of other entries can be seen here.



Greenland ice cap melt inevitable sea levels may rise 27cm

31 August 2022

We’re passed the time for warnings… a significant increase in sea levels is unavoidable, with the melting of the Greenland ice cap expected to add twenty-seven centimetres to global ocean tidemarks. It could be a whole lot more if (or when) other ice masses melt:

Major sea-level rise from the melting of the Greenland ice cap is now inevitable, scientists have found, even if the fossil fuel burning that is driving the climate crisis were to end overnight. The research shows the global heating to date will cause an absolute minimum sea-level rise of 27cm (10.6in) from Greenland alone as 110tn tonnes of ice melt. With continued carbon emissions, the melting of other ice caps and thermal expansion of the ocean, a multi-metre sea-level rise appears likely.

How did Electric Eels develop their electric charge?

22 August 2022

How did electric eels become… electric? It’s an intriguing question. After all, the seabed isn’t littered with the recharge stations electric vehicles use, so what’s the deal? Israel Ramirez, a retired biopsychologist, explains:

It isn’t hard to produce slight electric currents. Most animal cells keep sodium out and potassium in. Regulating the flow of these substances across the membranes of their cells produces a slight electric current because sodium and potassium have a positive charge. Each cell produces only a slight current, but you can get many volts by stacking cells in the same way people stack low voltage batteries to get a higher voltage.



Tasmanian Tiger de-extinction is a fairy tale science

22 August 2022

While a group of scientists believe they could revive Tasmanian Tigers — the species has been extinct since 1936 — and have the creatures roaming forests within a decade, not all scientists are convinced. In fact some believe the notion of bringing back the thylacine, is little more than a publicity stunt:

“De-extinction is a fairytale science,” Associate Professor Jeremy Austin from the Australian Centre for Ancient DNA told the Sydney Morning Herald, adding that the project is “more about media attention for the scientists and less about doing serious science”.

Time will tell.

The first year in the life of a mango tree time lapse video

25 July 2022

Incredible time lapse video footage of the growth of a mango tree, from being planted as a seed, to a year later, from the people at Boxlapse.

I once lived in house that had a mature mango tree in the back yard. It was sizeable, three metres, maybe a little higher, planted on the fence line. Now I know what I missed earlier on.

Forests now cover two percent of Iceland thanks to replanting

22 July 2022

In the distant past, forests and trees covered large parts of Iceland, about forty percent of the country. But when permanent settlers arrived over a thousand years ago, much of this growth was cleared to make way for agriculture and grazing, and firewood. Efforts to replant trees since the 1990s though have seen forest areas return to two percent of the country today.

That number may not seem like much, but since 1990, the surface area covered by forest or shrubs in Iceland has increased more than six times over – from 7,000 hectares to 45,000. In 20 years, the number is expected to be 2.6%.

Every little bit helps. It’s a hopeful reminder that it’s not too late to take steps of any sort to deal with climate change.

Don’t plant trees to combat climate change plant mini-forests

Planting trees is one way of mitigating the impact of climate change, but planting mini-forests is a more effective alternative, says American nature and conservation writer Hannah Lewis.

Mini-forests are more likely to nurture ecosystems, rather than single trees planted here and there, and, as a result, live longer. And better still, mini-forests can be established anywhere, even in densely populated urban areas, where there’s even a few spare square metres of land available.

A mini-forest is a small ecologically robust forest that can be planted by communities in parks and cities, in schoolyards and churchyards, and beside busy roads. It’s flipped traditional landscaping on its head. You get more biodiversity and a different appearance. It’s a dense band of multi-layer trees as opposed to the elegant but less ecologically useful line of single species down the side of the street.

Lewis’ call is based on the work of late Japanese botanist Akira Miyawaki, who advocated the planting of small forests with native species, as a way of fostering the emergence of ecosystems.
