Epigenetics Are Important To Evolutionary Success

Genetic diversity and long periods of time are things that are crucial for evolutionary adaptation. This made scientists wonder why invasive species, lacking genetic diversity, succeed quickly. And some ecologists are beginning to think that epigenetic factors might be modifying genes while leaving the genome intact.

Gene-Expression Indicates How Coral Reefs Will Handle Climate Change

Gene-Expression-Indicates-How-Coral-Reefs-Will-Handle-Climate-Change

Scientists have discovered a pattern of gene activity, which allows some corals to survive in higher temperatures. This suggests a way to predict how different corals will react to warmer waters, which are expected to result from climate change over the coming decades.

Elephants Make the Long Trek Across Deserts for Survival

Elephants Make the Long Trek Across Deserts For Survival

Elephants need to consume a minimum of 100 liters of water and 100 kilograms of vegetation daily, yet a small population of 350 manages to survive in the harsh Gourma region of Mali, south of the Niger River, where temperatures spike to 50˚C and vegetation is sparse.

Darcin in Mice Urine Attracts Other Mice

Darcin in Mice Urine Attracts Other Mice Repeatedly

Mice seem to be addicted to the scent of urine and repeatedly go back to spots where they found the excretions. Researchers have discovered that this behavior is triggered by a single protein in the urine of male mice.

In the past few years, the Amazon rainforest in Peru’s Ucayali region has been hit by two severe droughts, one in 2005 and another in 2010. These dry spells could become more frequent as temperatures in the tropical North Atlantic Ocean continue to rise and as thousands of square kilometers of forest are burnt to make way for farming.

Orangutans Learn Tool Use Through Social Observation

Orangutans Learn Using Tools Through Social Observation

A new study concludes that even very young Sumatran orangutans (Pongo abelii) start forming ideas about their world, and how and when to use certain tools. Ape cultural traditions might not be very different from the cultural traditions of humans.

Cloud Forest Trees Depend on Fog

Cloud Forest Trees Absorb Water Through Their Leaves From Fog

Trees in Costa Rica, as well as a number of plant species, in the tropical cloud forests quench their thirst by directly ingesting fog droplets through their leaves. These forests are in danger because of climate change, and a new study indicates that they’re even more fragile than previously thought.
