Scientists have long determined what extinct animals ate by analyzing carbon isotopes locked inside their fossil teeth. Recently researchers have discovered that the isotopic record depends on the animal’s body mass.

Alexandria Ang takes home the prestigious recognition for her research on a climate change-driven algae whose greenish blooms plague the Arabian Sea.

A new study has uncovered when and why the native vegetation that today dominates much of Australia first expanded across the continent.

Two new papers find that the line that divides the moist East and arid West is edging eastward due to climate change—and the implications for farming and other pursuits could be huge.

In a new study, researchers have mapped out a large variety of discarded pharmaceuticals dissolved throughout the Hudson River. They say that in some places, levels may be high enough to potentially affect aquatic life.

Braving the high seas and a curious shark, a team of scientists taps into the secret social life of a microbe that’s crucial for marine ecosystems.

On January 31 at 1:00 p.m. EST, Lamont-Doherty’s Hugh Ducklow and his colleagues will use National Science Foundation social media to discuss their research on Antarctic ecology.

Organic geochemist Pratigya Polissar is developing new tools to look at the history of plants and ecosystems on Earth over the past 20 million years.

The warmer, more acidic waters caused by climate change will affect the health of tiny marine organisms essential to the marine food web and important to the marine carbon cycle.

Three scientists explain what they’re learning about the ocean’s changing conditions. These discoveries will contribute to the sustainable management and conservation of marine resources, helping to secure food for current and future generations.

Plastic microbeads, common in soap, toothpaste and other consumer products, are flooding waters. A team from Lamont-Doherty Earth Observatory is doing the first large-scale assessment of their impact on New York’s waterways.

Last week, just days before Central Park’s big Ivory Crush, a Lamont-Doherty geochemist and his colleague sawed off samples of the confiscated ivory for DNA testing and radiocarbon dating. Their results could determine where and when each elephant was killed—which could help catch the poachers responsible.

A special section in the October issue of BioScience examines the effects of a single season of intense melting on two Antarctic ecosystems, tracking impacts all the way from microbial food webs to shifting penguin populations.

The tropics are already hot, and they’re getting hotter as global temperatures rise. A new study offers a glimpse into just how severely a couple more degrees could disrupt the region’s ecological map. The authors, from Lamont-Doherty Earth Observatory and the University of California, Berkeley, looked at potential effects of a 2°C rise in the average global temperature this century and asked: what would happen if all species tried to migrate to keep their average environmental temperature unchanged?

Researchers have predicted that as the planet is warmed by human-produced CO2, plants may add to the emissions and amplify the warming. Now, the most comprehensive global study of its kind yet suggests that this effect has limits, and that increases in plant respiration may not be as big as previously estimated. It shows that rates of increase slow in an easily predictable way as temperatures mount, in every region of earth, from tropics to tundra.
March 15, 2016One foggy spring morning just after a hard rain, Park Williams was tromping through the woods deep in Arkansas’ Ozark Mountains. Toiling down a steep slope, he supposedly was keeping a simultaneous eye out for rattlesnakes, copperheads, poison ivy and big old trees. Williams seemed mostly focused on the trees, though; attention to the other stuff was just slowing him down. Williams studies how forests react to changes in climate, and the Ozarks’ deeply dissected hills and hollers are a kind of ground zero for this.
