Articles on Paleoecology are primarily concerned with past ecosystems, climates, and geographies in studying prehistoric life
Sudden Collapse In Ancient Biodiversity: Was Global Warming The Culprit?Scientists have unearthed striking evidence for a sudden ancient collapse in plant biodiversity.
Earth Under Global CoolingThirty-four-million years ago, Earth changed profoundly. What happened, and how were Earth's animals, plants, oceans, and climate affected?
Ancient Climate Change: When Palm Trees Gave Way To Spruce TreesFor climatologists, part of the challenge in predicting the future is figuring out exactly what happened during previous periods of global climate change.
Lessons From The Past: Research Examines How Past Communities Coped With Climate ChangeResearch led by the University of Leicester suggests people today and in future generations should look to the past in order to mitigate the worst effects of climate change
Has The Mystery Of The Antarctic Ice Sheet Been Solved?A team of scientists travelled to Africa to find new evidence of climate change which helps explain some of the mystery surrounding the appearance of the Antarctic ice sheet.
Ancient Drought And Rapid Cooling Drastically Altered ClimateTwo abrupt and drastic climate events, 700 years apart and more than 45 centuries ago, are teasing scientists who are now trying to use ancient records to predict future world climate.
Plants Save The Earth From An Icy DoomWhen glaciers advanced over much of the Earth's surface during the last ice age, what kept the planet from freezing over entirely?
Climatic Chain Reaction Caused Runaway Greenhouse Effect 55 Million Years AgoThere are new findings regarding a phase of rapid global greenhouse warming that took place 55 million years ago.
Warming Climate Can Support Glacial Ice: It Did In Much Warmer TimesNew research challenges the generally accepted belief that substantial ice sheets could not have existed on Earth during past super-warm climate events
500 million years of errors: Brachiopod shells record shadow of arms race in ancient oceansA study of fossils from the Paleozoic Era, collected across the world, reveals that ancient brachiopods were little bothered by predators
Alligator egg development at prehistoric oxygen levelsThe development of bone structures in alligator eggs raised under varying oxygen concentrations creates a link to fossil records of the evolution of vertebrates and prehistoric atmospheric oxygen concentrations
Ancient global warming drove early primates' dispersalThe continent-hopping habits of early primates have long puzzled scientists
Volcanic blast likely killed and preserved juvenile fossil plesiosaur found in AntarcticaAmid 70-mile-an-hour winds and freezing Antarctic conditions, a research team has recovered the well-preserved fossil skeleton of a juvenile plesiosaur
Study shows largest North America climate change in 65 million yearsThe largest climate change in central North America since the age of the dinosaurs 65 million years ago...
Predicting Pleistocene climate from vegetation in North AmericaClimates at the Last Glacial Maximum have been inferred from fossil pollen assemblages, but these inferred climates are colder for eastern North America than those produced by climate simulations.
Temporal response of the tiger salamander (Ambystoma tigrinum) to 3,000 years of climatic variationAmphibians are sensitive indicators of environmental conditions and show measurable responses, such as changes in phenology, abundance and range limits to local changes in precipitation and temperature regimes.
An outer-ramp brachiopod assemblage from the uppermost San Juan Formation (middle Arenig), northern Argentine Precordillera: paleoecologic and biogeographic implicationsThe paper describes the brachiopod fauna recovered from the outer-ramp deposits developed at the top of the San Juan Formation in the Guandacol depocenter.
From Icehouse To Hothouse: Melting Ice And Rising Carbon Dioxide Caused Climate ShiftThree hundred million years ago, Earth's climate shifted dramatically from icehouse to hothouse, with major environmental consequences.
Greenhouse Gas Effect Consistent Over 420 Million YearsNew calculations show that sensitivity of Earth's climate to changes in the greenhouse gas carbon dioxide (CO2) has been consistent for the last 420 million years
West African Ocean Sediment Core Links Monsoons To Global Climate EvolutionMonsoons, the life-giving, torrential rains of Asia and Africa, have an ancient, unsuspected connection to previous Ice Age climate cycles
