A new study of algal bloom activity in dozens of freshwater lakes around the world provides an answer: For the past 30 years, lakes nearly everywhere have been experiencing more frequent and severe toxic algal blooms—and a changing climate is one reason why.
Researchers at theCarnegie Institution for Scienceused satellite data collected over the past three decades to examine large freshwater lakes across six continents. They searched through more than 72 billion data points to identify statistically significant patterns in algal bloom intensity and found that the severity of algal blooms has increased in over two-thirds of the 71 large lakes studied across 33 countries.
SCIENTIFIC NAME:Antilophia bokermanni POPULATION: About 800 adults IUCN STATUS: Critically Endangered TREND: Decreasing HABITAT: Lower and middle levels of tall, humid forest, with an abundance of vines.
The Araripe Manakin’s Critically Endangered status, which has led to its listing as anAlliance for Zero Extinction(AZE) species, has also focused attention on the importance of conserving its unique habitat. This habitat determines not only this bird’s continued survival but also the quality of life for thousands of people living in this largely impoverished region of northeastern Brazil.
In 2003, the first information about the Araripe Manakin’s biology and threats to its survival were presented in a management plan aimed at local stakeholders. Just this year, the bird became the first species in Brazil to receive a National Conservation Action Plan. It is now a widely recognized symbol for biodiversity, natural resources conservation, and the importance of environmental sustainability.
What do pink dolphins and leafy sea dragons have in common? They both benefit from two amazingly unique and little-known reefs on opposite sides of the world. Despite their geographic differences, the Amazon Reef and the Great Southern Reef have some striking similarities.
Scientists estimate the Amazon Reef’s size could span 56,000 km2 near the mouth of the Amazon River. Not bad for a reef system that nobody expected to be there! Because of its unique nature, the critters that live amongst the Amazon Reef are very precious. Between 2010 and 2014, scientists undertook three surveys of the area, and they believe they have found new species of fish and sponges.
