A Helpful Invader
Invasive species are a great concern for the health and stability of ecosystems. They are defined as plants, animals or pathogens that are non-native to the ecosystem under consideration and whose introduction causes or is likely to cause harm. It is that latter consideration that isn’t always obvious.
Squeaking By
Amphibians are one of the most threatened groups of animals on the planet. Since the late 1980s, scientists have measured dramatic population declines from locations all over the world. The plummeting amphibian populations are perceived to be one of the most critical threats to global biodiversity. According to the IUCN, about 1 of every 3 amphibian species is facing extinction. Some of the greatest threats facing amphibians include climate change, disease, and habitat destruction.
Saving Saharan Oases
An oasis is an isolated area of vegetation in a desert, typically surrounding a spring or similar water source such as a pond or a small lake. Oases can provide habitat for animals as well as people. Oases have long been essential for trade and transportation routes in desert areas; caravans typically travel via oases so that supplies of water and food can be replenished.
Fencing Out People And Animals
The flood of refugees from the Middle East and Africa has prompted governments in the Balkan countries to erect hundreds of miles of border fences. Countries like Slovenia have put up razor-wire security fences to stem the tide of migrants. These border fences are built with little if any consideration of the environmental impacts on wildlife.
Livestock And Antibiotics
According to the FDA, approximately three-quarters of all antibiotics used in the U.S. are fed to livestock for non-therapeutic purposes. This routine administration of antibiotics promotes the development of antibiotic-resistant bacteria, which can spread to animals and humans. And as antibiotic-resistant bacteria spreads, medicines used to treat human diseases can become less effective. Antibiotic resistant infections kill 90,000 Americans each year.
Changing National Parks
America’s National Parks are special places of incomparable beauty and fascination. When the National Park Service was first created 100 years ago, it was instructed to leave these places “unimpaired for the enjoyment of future generations.” We now live in a time when the changing climate is altering many aspects of the landscape including in many national parks. The parks are protected, but they are changing.
Lake Baikal
Lake Baikal is an ancient and massive body of freshwater found in the mountainous Russian region of Siberia. Deep and voluminous, Lake Baikal holds 20% of the planet’s unfrozen freshwater. And it’s often been described as the world’s cleanest and most pristine lake.
Wildlife Corridors
It is widely thought that we are in the midst of the 6th great mass extinction of species on Earth and, unlike the previous ones that were caused by things like asteroid impacts or ice ages, this one is caused by us. Our impact on the climate, on natural resources, on landscapes and habitats, and more, has wreaked havoc on ecosystems across the globe.
Wiping Out Wildlife
According to a new report from the World Wildlife Fund, the world’s animal populations have suffered widespread population declines in the last half century. And thousands of species are now scrambling to survive.
Why Do Animals Eat Ocean Plastic?
It’s no secret that there is a lot of plastic debris in our oceans. In fact, scientists estimate that there is more than 165 million tons of plastic trash swirling about in our oceans today, with an additional 8.8 million tons flowing in every year. And as the oceans swell with plastic litter, hundreds of marine species are ingesting the stuff – often with dire consequences.
Animal Welfare
One week from today many of us will head to the polls to make critical decisions about who will represent us in the White House, in Congress, and in state and local offices. And in several states, people will also vote on the humane treatment of animals.
Lessons From The Forest
For more than half a century, scientists have converged on Hubbard Brook Experimental Forest in New Hampshire’s White Mountains to explore how forest ecosystems work. The site was established by the U.S. Forest Service to study the relationship between forests and New England’s water supply. In the 1960s, inquiry was expanded to include ecology, biogeochemistry, and studies of birds and other animals.
Should We Rescue Distressed Animals?
From time to time, we encounter wild animals in distress. A baby robin falls out of its nest. A fawn is orphaned when its mother is hit by a car. A bald eagle staggers on the ground, unable to fly.
Alligator Security Guards
Complex ecosystems often create complex interrelationships between animals. One of the more surprising ones is that between waterbirds and alligators in the Florida Everglades.
Are All Invasive Species Bad?
The conventional wisdom is that invasive species are bad news and we constantly hear about the dangers of foreign plants and animals moving into new territories.
Duping Poachers
According to the Humane Society of the United States, hunters legally kill tens of millions of animals every year. But hunters also illegally kill just as many animals – if not more – often either on closed lands or out of season. Few perpetrators of this deadly crime against wildlife are ever caught or punished.
Lake Ohrid: Respecting An Elder
Nestled in the mountainous border between southwestern Macedonia and eastern Albania, Lake Ohrid is a deep, ancient lake. Its waters provide refuge to hundreds of plants and animals that live nowhere else, including seventeen species of fish.
Primates And Toucans As Climate Allies
Many of us have a soft spot for primates and toucans. These charismatic creatures are prized for their intellect and beauty. But did you know they also play a vital role in combating climate change?
