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.

Scientists detect molten rock layer hidden under Earth's tectonic plates      (via sciencedaily.com) 

Scientists have discovered a new layer of partly molten rock under the Earth's crust that might help settle a long-standing debate about how tectonic plates move. The molten layer is located about 100 miles from the surface and is part of the asthenosphere, which is important for plate tectonics because it forms a relatively soft boundary that lets tectonic plates move through the mantle. The researchers found, however that the melt does not appear to notably influence the flow of mantle rocks. Instead, they say, the discovery confirms that the convection of heat and rock in the mantle are the prevailing influence on the motion of the plates.

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.

Study reveals new clues about how 'Earth's thermostat' controls climate      (via sciencedaily.com) 

Rocks, rain and carbon dioxide help control Earth's climate over thousands of years -- like a thermostat -- through a process called weathering. A new study may improve our understanding of how this thermostat responds as temperatures change.

Climate change may cut US forest inventory by a fifth this century      (via sciencedaily.com)     Original source 

A study found that under more severe climate warming scenarios, the inventory of trees used for timber in the continental United States could decline by as much as 23% by 2100. The largest inventory losses would occur in two of the leading timber regions in the U.S., which are both in the South.

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.

Deer browsing is just one of many factors shaping North American forests      (via sciencedaily.com) 

In a new study, a research team discovered evidence that browsing by white-tailed deer had relatively little long-term impact on two tree species in a northern forest.

Understanding plants can boost wildland-fire modeling in uncertain future      (via sciencedaily.com) 

A new conceptual framework for incorporating the way plants use carbon and water, or plant dynamics, into fine-scale computer models of wildland fire provides a critical first step toward improved global fire forecasting.

Immense diversity and interdependence in high temp deep-sea microorganism communities      (via sciencedaily.com) 

A new study finds that microorganisms live in richly diverse and interdependent communities in high-temperature geothermal environments in the deep sea. By constructing genomes of 3,635 Bacteria and Archaea from 40 different rock communities, researchers discovered at least 500 new genera and have evidence for two new phyla. Samples from the deep-sea Brothers volcano were especially enriched with different kinds of microorganisms, many endemic to the volcano. The genomic data from this study also showed that many of these organisms depend on one another for survival. Some microorganisms cannot metabolize all of the nutrients they need to survive so they rely on nutrients created by other species in a process known as a 'metabolic handoff.'

New discovery: Endangered Amami rabbit disperses seeds for non-photosynthetic plant      (via sciencedaily.com) 

Seed dispersal is an essential process for the evolution and ecology of terrestrial plants, making discoveries of uncommon seed dispersal agents particularly interesting. Scientists now reveal that the Amami rabbit (Pentalagus furnessi) is a major seed dispersal agent for the non-photosynthetic plant Balanophora yuwanensis. To the best of our knowledge, this is the first known instance of rabbits serving as seed dispersal agents in Asia.
