Long-term restoration of a biodiversity hotspot hinges on getting seeds to the right place at the right time      (via sciencedaily.com) 

New research shows that degraded savanna ecosystems can reap lasting benefits from a single seeding of native understory plants. Once a diverse understory of savanna plants became established, its long-term persistence was relatively unaffected by environmental factors -- with one exception. Higher temperatures during the height of the growing season were associated with poorer long-term survival among some species, indicating one threat posed by a warming climate.

Loss of reptiles poses threat for small islands where humans may have caused extinctions      (via sciencedaily.com) 

A new examination of ancient and current species of reptiles conducted by paleobiologists reveals the serious impact of the disappearance of even a few species of reptiles in some island areas. The study has startling conclusions about how, on smaller islands in the Caribbean where human impact was greatest, extinctions have led to the loss of up to two-thirds of the supports for the ecosystem that native reptile species once provided there.

Voiceless frog discovered in Tanzania      (via sciencedaily.com)     Original source 

Researchers discovered a new species of frog in Africa that has an unusual trait: it's completely silent. The Ukaguru spiny-throated reed frog does not croak, sing or ribbit. Found in Tanzania's Ukaguru Mountains for which it is named, Hyperolius ukaguruensis is among the few frogs around the world that do not vocalize to other frogs.

Protected areas fail to safeguard more than 75% of global insect species      (via sciencedaily.com) 

Insects play crucial roles in almost every ecosystem -- they pollinate more than 80% of plants and are a major source of food for thousands of vertebrate species -- but insect populations are collapsing around the globe, and they continue to be overlooked by conservation efforts. Protected areas can safeguard threatened species but only if these threatened species actually live within the areas we protect. A new study found that 76% of insect species are not adequately covered by protected areas.

With rapidly increasing heat and drought, can plants adapt?      (via sciencedaily.com) 

As deserts expanded their range over the past 5-7 million years, many plants invaded the new biome and rapidly diversified, producing amazing adaptations to drought and heat. Can plants continue to adapt to increasing aridity caused by climate change? A new study that addressed the origins of desert adaptation concluded that one group of desert plants, rock daisies, came preadapted to aridity, likely helping them survive desert conditions. Not all plants may be so lucky.

Mixing between species reduces vulnerability to climate change      (via sciencedaily.com) 

New research provides rare evidence that natural hybridization can reduce the risk of extinction of species threatened by climate change. Researchers have identified genes that enable Rainbowfish to adapt to climate variations across the Australia using environmental models to work out how much evolution will likely be required for populations to keep pace with future climate change.

Ancestral variation guides future environmental adaptations      (via sciencedaily.com) 

The speed of environmental change is very challenging for wild organisms. When exposed to a new environment individual plants and animals can potentially adjust their biology to better cope with new pressures they are exposed to -- this is known as phenotypic plasticity. New research shows that early plasticity can influence the ability to subsequently evolve genetic adaptations to conquer new habitats.

In a new breakthrough, researchers have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather than one. Trivial as it may seem to those uninitiated in quantum, this colossal breakthrough allows researchers to create a phenomenon known as quantum mechanical entanglement. This in turn, opens new doors for companies and others to exploit the technology commercially.

There are often too few flowering plants in agricultural landscapes, which is one reason for the decline of pollinating insects. Researchers ave now investigated how a mixture of crops of faba beans (broad beans) and wheat affects the number of pollinating insects. They found that areas of mixed crops compared with areas of single crops are visited equally often by foraging bees.
