Ecosystem Ecology

In seinen dreiundneunzig Lebensjahren hat David Attenborough einschneidende Veränderungen unserer natürlichen Lebensbedingungen miterlebt. Als er zur Welt kam, gab es noch auf allen Kontinenten Wildnis. Heute hingegen hat die Spezies Mensch sich vervierfacht, die entlegensten Winkel des Planeten erobert und drängt Fauna und Flora immer weiter zurück. Dadurch hat sich die Aussterberate im Vergleich zu ruhigeren erdgeschichtlichen Zeiten um das 100- bis 1000fache erhöht.

In Nature's Best Hope (Young Readers' Edition), Tallamy empowers kids to use their own yards to help combat the negative effects of climate change. He does so by breaking down complex concepts into simple terms and real-world examples that kids can easily grasp. Black and white photographs help further clarify concepts. In addition to sharing the science, Tallamy encourages kids to take direct action. Some of these ideas include planting an oak tree at home. If that’s too large of a task, he suggests they can plant asters—a beautiful flower whose pollen bees use to feed their young.

Sally Coulthard explores the miraculous world of the earthworm, the modest little creature without whom life as we know it would not be possible. For Charles Darwin - who estimated every acre of land contained 53,000 earthworms - the humble earthworm was the most important creature on the planet. And yet, most people know almost nothing about these little engineers of the earth. We take them for granted but, without the earthworm, the world's soil would be barren and our gardens, fields and farms wouldn't be able to grow the food and support the animals we need to survive.

Genius Ideas for Planetary Healing is about envisioning a healthier planet for all. It’s a survey of the innovations and transformations that can support a world where humanity and nature both prosper. Building off of foundational concepts, we explore the challenges we face and the inspired responses that we are starting to take.

A mudança climática é real, mas não é o fim do mundo. Não é sequer nosso maior problema ambiental. Michael Shellenberger tem lutado por um planeta mais verde por décadas. Ajudou a salvar as últimas sequoias ameaçadas do mundo, co-criou o que seria o predecessor do atual Novo Acordo Verde (Green New Deal), além de, juntamente com cientistas climáticos e ativistas, liderar uma ação bem sucedida para manter as usinas nucleares funcionando, assim evitando os famosos "picos de emissão".

In the 1930s, the last wolves disappeared from Yellowstone National Park. Without them, elk herds overran the plains. Bears starved, rabbit families shrunk and birds flew away to new homes. Then plants and trees started to die off, too—even the flow of rivers was affected. Could the park be saved...by the wolves it had lost? After years of planning, in 1995 a team of experts was ready to find out. They carefully relocated 14 wolves from the Canadian Rockies to Yellowstone. This is the story of their homecoming.

The COVID-19 pandemic has demonstrated our fragility as a species. Humanity was attacked by a previously unknown virus that spread very rapidly, thanks to a speed of population mobility never before seen in human history. It succeeded in creating the complete upset of the global socioeconomic system. Such an event gives us an important stimulus to reevaluate health in the context of a circular system that encompasses humans and the environment in which we live. The key challenge we face is the discovery of novel paths to crisis resolution.

Over the canyon, the sun scalds the air and bakes the desert mud to stone. But under the shade of the canyon hides another world, where bighorn sheep bound from rock to rock on the hillside, roadrunners make their nests in sturdy cacti, and banded geckos tuck themselves into the shelter of the sand. Discover the wonders concealed in the curves of the canyon and all the secret life hidden in its arms.

Ziehen Sie Ihre Schwimmflossen an und setzen Ihre Sauerstoffmaske auf, tauchen Sie ins Meer und lassen Sie sich in einem ruhigen Tempo unter Wasser treiben. Verspielte Delfine machen klickende Geräusche, wenn sie vorbeischwimmen, und deine Maske erzeugt winzige, metallisch klingende Blasen, die zur Oberfläche aufsteigen. Vielleicht hören Sie sogar ein paar Walgesänge von den sanften Giganten des Ozeans.

Mosquitoes are among the most notorious insects globally, infamous for their role as vectors of various deadly diseases. Yet, their existence is a complex interplay of detrimental and beneficial effects on both ecosystems and human societies.

Drawing upon his vast knowledge of the environment, biology, botany, and history, Ronald R. Van Stockum, Jr. has written a love letter to Kentucky. The lay person as well as the expert will understand as he describes the state’s evolution - its history, original land surface, the river-cut gorges, the mountains, and the lakes. Along with thorough documentation, the writer gives us a poetic description of this “...verdant state, lush in its heat, humidity, and rainfall. The diversity and abundance of life was immediately evident to all who came here”.

In Elkhorn Slough, an inlet on the California coast, seagrass grows healthy and strong in the shallow water. This healthy seagrass baffled marine biologist Brent Hughes. The scientist expected this estuary to be overrun with algae, causing the seagrass to die. Why was the seagrass thriving? As Brent investigated, signs pointed to an unexpected player helping to keep the seagrass healthy: sea otters! What do these top predators have to do with an aquatic grass at the opposite end of the food chain?
