Plants may have exerted greater influence on our terrestrial ecosystems than the megaherbivores that used to roam our landscapes, according to new research.

People in crowded urban areas – especially poor areas – see fewer songbirds such as tits and finches, and more potential “nuisance” birds, such as pigeons, magpies and gulls, new research shows.

Since hitching unsolicited rides in boat ballast water in the late 1980s, invasive quagga mussels (Dreissena rostriformis bugensis), which are native to Ukraine, have caused massive changes to the ecology of the Great Lakes.  These invasive mussels have also taken a toll on the Great Lakes recreational and commercial fisheries, which are valued at $4-7 billion annually according to Michigan Sea Grant.

A range of less than one degree Fahrenheit (or half a degree Celsius) of climate warming over the next century could make all the difference when it comes to the probability of future ice-free summers in the Arctic, new CU Boulder research shows.

The Atlantic overturning – one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards – is weaker today than any time before in more than 1000 years. Sea surface temperature data analysis provides new evidence that this major ocean circulation has slowed down by roughly 15 percent since the middle of the 20th century, according to a study published in the highly renowned journal Nature by an international team of scientists. Human-made climate change is a prime suspect for these worrying observations.

A joint research project of the Chronology Laboratory of the Finnish Museum of Natural History and Natural Resources Institute Finland (Luke) suggests that the years 536 and 541–544 CE were very difficult for many people.

Baby fish will find it harder to reach secure shelters in future acidified oceans – putting fish populations at risk, new research from the University of Adelaide has concluded.

Researchers have good news for growers. Farmers raising a nitrogen-hungry crop like sweet corn may save up to half of their nitrogen fertilizer cost. The key: using a faba bean cover crop.

Cheetahs in the Serengeti National Park adopt different Two male cheetahs eat a killstrategies while eating to deal with threats from to​​​​​​​p predators such as lions or hyenas. A new study in Springer’s journal Behavioral Ecology and Sociobiology shows that male cheetahs and single females eat their prey as quickly as possible. Mothers with cubs, on the other hand, watch out for possible threats while their young are eating in order to give them enough time to eat their fill. The research was led by Anne Hilborn of Virginia Tech’s College of Natural Resources and Environment in the US.

Social gadflies in an organization are the new superheroes of conservation, according to a study in this month's Nature Sustainability.
