The North Atlantic Ocean Circulation is a double-edged sword when it comes to ocean acidification. In the past, it has kept the North Atlantic Ocean less acidic – and more hospitable – than the Pacific Ocean. Today, the same circulation has the potential toconvey fast acidification to the ocean depth as climate change alters both the atmosphere and the surface ocean.
Businesses are increasingly swayed by their customer’s preferences for environmentally friendly brands, a phenomenon known as “green loyalty.” Mounting customer pressure is pushing the growing cruise industry to seek more sustainable solutions.
Engaging community members in environmental monitoring can help land managers understand how ecosystems respond to human activities. Data collected by students can accurately reflected a stream’s recovery after restoration work.
Human activity is increasing carbon dioxide levels in the atmosphere, causing the ocean to absorb more carbon dioxide as well. New research shows that increasing oceanic carbon dioxide levels are also fluctuating with the seasons. Over time, these fluctuations are becoming more dramatic. As a result, marine animals will be pushed earlier than expected towards threatening conditions.
Scientists from the Institute for Conservation Research at the San Diego Zoo and UCLA are researching animal decision making across disciplinary boundaries. In a recent study, they investigated how animal decision making can be affected by human impacts on the environment. They argue that understanding the ways animals respond to different situations can help scientists conserve species more effectively.
A longstanding conservation scheme known as payment for ecosystem services aims to incentivize forest protection by putting a price on the services forests provide, but questions remain whether the payments generated are going to right people . A recent analysis conducted in Costa Rica indicates that indeed further work is needed to reach rural poor populations that depend on forests for their livelihoods.
As the summer sea ice melts in the Arctic, polar bears struggling to hunt seals are increasingly turning to sea-birds for food. New scientific research suggests that this change in the polar bear diet could severely reduce sea ducks populations and deprive Arctic peoples of a major source of food and livelihood.
The stories about the poaching of African elephants are deeply imbedded in the carbon isotope tracers that make up the prized tusks. A group of scientists used these tracers to uncover the realities of poaching activities threatening Africa’s elephants today.
Drought has become increasingly prevalent in many parts of the world, but how it will affect ecosystems is often poorly understood. In the Yellow River Delta scientists discovered that another factor, natural enemies, hinder the ability of plants to recover from drought.
