Research shows that boreal forests, like those across much of Northern Europe and Canada, have higher levels of variability in their structure and dynamics when unmanaged, improving their biodiversity and the stability of their ecosystems. These unmanaged forests also have a higher proportion of older trees than those used in industrial forest rotation – around 70-100 years in Canadian boreal forests.
Some plants are capable of warding off attack by slugs and snails, but many of our favourite garden flowers and vegetables seemingly cannot get their act together. Should we even attempt to grow Hostas, for example?
Recently, a number of the world’s leading scientists, indigenous leaders, and advocates have been engaged in something bold: asking exactly what is required to stop the mass extinction of life on Earth and save a living planet. And the answer, after numerous reviews of the evidence for what it would take to achieve comprehensive biodiversity conservation, has become clear: fully protect half the Earth (or more) in an interconnected way.
Most people in the western world learn that the giant panda has striking black and white colouration at kindergarten; but are never told why! The question is problematic because there are virtually no other mammals with this sort of colouration pattern, making analogies difficult. At UC Davis and CSU Long Beach, we instead decided to break up the external appearance of giant pandas into different regions
Yet despite their brutish appearance, marine iguanas are extremely placid herbivores, posing a threat only to the algae upon which they feed. We now know that these creatures represent one of the oldest living lineages of the archipelago and as such, their evolution is deeply intertwined with the history of the islands themselves, a discovery foreshadowed by Darwin‘s observation that “They assuredly well become the land they inhabit”.
Less than a year after the governments of the world came together to sign the Paris Agreement on climate change, the United States has inaugurated a new president, Donald Trump, who denounces the whole idea as a Chinese hoax. How did we get here?
Escherichia coli (E. coli) is a common bacteria found in the the lower intestine of warm-blooded animals, including humans. Whilst most strains are harmless, some can cause serious gastroenteritis, or food poisoning. However, one special strain, E. coli strain Nissle 1917 (EcN), is specifically used to prevent digestive disruption. Since its discovery 100 years ago, EcN is probably the most intensely investigated bacterial strain today.
The People’s Climate Movement, made up of dozens of organizations working to fight the climate crisis, held their first march in September 2014. On Saturday, 29 April, activists will once again march to demand climate action. As they protest the Trump administration’s drastic approach to climate change, the People’s Climate Movement will aim to “show the world and our leaders that we will resist attacks on our people, our communities and our planet.”
Earth Day is celebrated globally on 22 April in support of environmental protection. The theme for 2017’s Earth Day is “Environmental & Climate Literacy” – and we couldn’t think of a better way to celebrate knowledge of the environment and climate than with a reading list. These books, chapters, and articles can add to your understanding of Earth through topics such as climate change, natural phenomena, and what practical steps are being taken to help protect our planet.
Muir knew that the wilds surrounding him not only fed his soul but sustain us all. Too many of our current elected officials have forgotten his lesson. They seek to sell off our public lands throughout my western home to view them as little more than sources of oil and gas, and to strip federal oversight that has kept these lands there for all of us, generation after generation.
While much of the rhetoric surrounding the Anthropocene has been markedly negative, there has recently been a push by many scientists for a more positive narrative. Specifically, researchers are posing the question: can the Anthropocene be good? A good Anthropocene would balance the preservation of the natural world with realistic societal needs and consumption.
Shortly before sunset, especially in winter from October to February, flocks of tens of thousands of European starlings (Sturnus vulgaris) fly in aerobatic displays called murmurations. The flocks swirl and morph, transforming from, for example, a teardrop shape into a vortex, and then into a long rope. The spontaneous synchronised flock turns as if of one mind.
Fast forward to 2017: with a few possible exceptions, Congress hasn’t addressed any significant environmental problems for over a quarter century and has blocked important environmental legislation; President Trump has promised to gut the EPA; and its new administrator, Scott Pruitt, as Attorney General of Oklahoma, sued the Agency over and over again to kill major environmental regulations.
From time immemorial, humans have yearned to know what lies ahead. Setting the context is a three-thousand-year romp through the ‘history of the future’ illustrating how our forebears tried to influence, foretell or predict it. Examples extend from the prophets and sibyls to Plato and Cicero, from the Renaissance to the European Enlightenment.
CNN’s Don Lemon recently pushed back when Paris Dennard, a conservative pundit, insisted on calling a story they were covering (the cost to the taxpayer of President Trump’s frequent visits to Florida) “fake news.” As Lemon said, “Fake news is when you put out a story to intentionally deceive someone and you know that it is wrong.” Lemon provided an excellent definition for fake news, but it’s also a great definition for “propaganda”.
A finger on a touch pad can glide us across the globe; we can casually sweep from the view that an albatross apparently gets as it flies to its nest site in South Georgia, to what a vulture apparently sees when looking for carrion in Tanzania’s Ngorongoro Crater. The notion that these really are bird’s eye views is deeply engrained. When we use the term “bird’s eye view”, we actually think that this is how the world looks to a bird.
