Study reveals which outdoor lighting minimizes harm to insects

NASA
Researchers examined an area in the Amazon basin that had never before been exposed to artificial light.
Insects make our lives better they are an important piece of the food chain and they pollinate the plants we use for food and backyard ambiance. But humans make those jobs more difficult, in part because the artificial light we use alters insects’ normal behavior.
New research by UCLA and the Smithsonian Conservation Biology Institute shows how the kind of light people use makes a big difference, even in one of the buggiest places on Earth the Amazon River basin. The study, published March 16 in Insect Conservation and Diversity, reveals that a certain kind of light minimizes humans’ impact on natural systems. ....

Artificial light affects plant pollination even during the daytime

The use of artificial light at night around the world has increased enormously in recent years, causing adverse effects on the survival and reproduction of nocturnal organisms. Artificial light at night interferes with vital ecological processes such as the nighttime pollination of plants by nocturnal insects, which could have consequences for agricultural crop yields and reproduction of wild plants.
Scientists from the University of Zurich and Agroscope have now demonstrated for the first time that artificial light at night also adversely affects insects pollination behavior during the daytime. In an experiment, they used commercial streetlamps to illuminate natural plant-pollinator communities during the nighttime on six natural meadows. Six other natural meadows ....

Trawling for Fish May Unleash as Much Carbon as Air Travel, Study Says
The report also found that strategically conserving some marine areas would not only safeguard imperiled species but sequester vast amounts planet-warming carbon dioxide, too.

March 17, 2021
For the first time, scientists have calculated how much planet-warming carbon dioxide is released into the ocean by bottom trawling, the practice of dragging enormous nets along the ocean floor to catch shrimp, whiting, cod and other fish. The answer: As much as global aviation releases into the air. ....

The trouble of being tall

The giraffe is a truly puzzling animal. With its exceptional anatomy and suite of evolutionary adaptations, the giraffe is an outstanding case of animal evolution and physiology. Now, an international team of researchers from the University of Copenhagen and Northwestern Polytechnical University in China have produced a high-quality genome from the giraffe and investigated which genes are likely to be responsible for its unique biological features.
The extraordinary stature of the giraffe has led to a long list of physiological co-adaptations. The blood pressure of the giraffe, for instance, is twice as high as in humans and most other mammals to allow a steady blood supply to the lofty head. How does the giraffe avoid the usual side effects of high blood pressure, such as severe dam ....

Deforestation taking a heavy toll on international bird haven

Credit: Pablo Negret
An analysis has found deforestation is severely affecting forest bird species in Colombia, home to the greatest number of bird species in the world.
University of Queensland-led research, steered by Dr Pablo Negret, analysed the impact of deforestation on 550 bird species, including 69 only found in the South American nation.
Our study has shown an astonishing reduction in bird species habitat, Dr Negret said.
One third of the forest bird species in Colombia have lost at least a third of their historical habitat, and that s just using the most recent data we have available - from 2015.
Moreover, 18 per cent or 99 species have lost more than half of their historical habitat to date. ....
