Genetics as conservation tool for endangered chimpanzees      (via sciencedaily.com) 

The western chimpanzees of Guinea are threatened by mining activities. Using a novel genetic approach, researchers have collected information on population size and community structure of the endangered species. These data provide an important baseline to assess the impact of mining.

Microneedle-based drug delivery technique for plants      (via sciencedaily.com) 

The agriculture industry is under pressure to adopt sustainable and precise agricultural practices that enable more efficient use of resources due to worsening environmental conditions resulting from climate change, an ever-expanding human population, limited resources, and a shortage of arable land. As a result, developing delivery systems that efficiently distribute micronutrients, pesticides, and antibiotics in crops is crucial to ensuring high productivity and high-quality produce while minimising resource waste. However, current and standard practices for agrochemical application in plants are inefficient. These practices cause significant detrimental environmental side effects, such as water and soil contamination, biodiversity loss and degraded ecosystems; and public health concerns, such as respiratory problems, chemical exposure and food contamination.

Thousands of native plants are unphotographed, and citizen scientists can help fill the gaps      (via sciencedaily.com) 

New research finds almost 4000 Australian plant species have not been photographed before in the wild, which may lead to their extinction.

Remarkable squirting mussels captured on film      (via sciencedaily.com) 

Researchers have observed a highly unusual behavior in the endangered freshwater mussel, Unio crassus. The jets disturb the river surface and attract fish. Mussel larvae in the jets can then attach to the gills of the fish and complete their metamorphosis into adults.

Island-inhabiting giants, dwarfs more vulnerable to extinction      (via sciencedaily.com) 

Island-dwelling mammal species often expand or contract in size, becoming giant or dwarf versions of their mainland counterparts. A new Science study from a global team shows that those giants and dwarfs have faced extreme risk of extinction -- an existential threat exacerbated by the arrival of humans.

Paleontologists flip the script on anemone fossils      (via sciencedaily.com) 

Billions of sea anemones adorn the bottom of the Earth's oceans -- yet they are among the rarest of fossils because their squishy bodies lack easily fossilized hard parts. Now a team of paleontologists has discovered that countless sea anemone fossils have been hiding in plain sight for nearly 50 years. It turns out that fossils long-interpreted as jellyfish were anemones. To do so, a team of scientists has simply turned the ancient animals upside down.

Plant roots fuel tropical soil animal communities      (via sciencedaily.com) 

A research team has shed new light on the importance of plant roots for below-ground life, particularly in the tropics. Millions of small creatures toiling in a single hectare of soil including earthworms, springtails, mites, insects, and other arthropods are crucial for decomposition and soil health. For a long time, it was believed that leaf litter is the primary resource for these animals. However, this recent study is the first to provide proof that resources derived from plant roots drive soil animal communities in the tropics.

An internal thermometer tells the seeds when to germinate      (via sciencedaily.com) 

Germination is a crucial stage in the life of a plant as it will leave the stage of seed resistant to various environmental constraints (climatic conditions, absence of nutritive elements, etc.) to become a seedling much more vulnerable. The survival of the young plant depends on the timing of this transition. It is therefore essential that this stage be finely controlled. Botanists have now discovered the internal thermometer of seeds that can delay or even block germination if temperatures are too high for the future seedling. This work could help optimize plant growth in a context of global warming.

Scientists use satellites to track earth 'greening' amid climate change      (via sciencedaily.com) 

Researchers found changes in 'greening,' or the amount of leaves plants are able to produce, will play a significant role in how much carbon dioxide plants capture and store.

Wisconsin cave holds tantalizing clues to ancient climate changes, future shifts      (via sciencedaily.com) 

A newly published study of a stalagmite found in Cave of the Mounds reveals previously undetected history of the local climate going back thousands of years. Researchers describe evidence for an ice age punctuated by massive and abrupt warming events across much of the Northern Hemisphere.

Earlier take-off could lead to fewer bumblebees and less pollination      (via sciencedaily.com) 

With the arrival of spring, bumblebee queens take their first wing beat of the season and set out to find new nesting sites. But they are flying earlier in the year, as a result of a warmer climate and a changing agricultural landscape, according to new research.

Waxing and waning of environment influences hominin dispersals across ancient Iran      (via sciencedaily.com) 

A world-first model of paleoclimate and hydrology in Iran has highlighted favourable routes for Neanderthals and modern human expansions eastwards into Asia. The findings reveal that multiple humid periods in ancient Iran led to the expansions of human populations, opening dispersal route across the region, and the possible interactions of species such as Neanderthals and our own Homo sapiens.

Prehistoric sea monster may have been shorter, stouter, than once believed      (via sciencedaily.com) 

A big fish story? Maybe so: The greatest sea monster of the Devonian Period (Dunkleosteus terrelli) may be getting downsized. A new article contents that the famous sea monster of the Age of Fishes may not have neared 30-feet in length, as long believed, but topped off at maybe 13 feet. The new assertion brings attention to a famously fierce looking armored fish from 360 million years ago -- and maybe a new debate.

Deforestation in the tropics linked to a reduction in rainfall      (via sciencedaily.com) 

Deforestation is resulting in reduced rainfall across large parts of the tropics, according to new research. People living in tropical forest communities have often complained that the climate gets hotter and drier once trees are cleared but until now, scientists have not been able to identify a clear link between the loss of tree cover and a decline in rainfall.

Jurassic shark: Shark from the Jurassic period was already highly evolved      (via sciencedaily.com) 

Cartilaginous fish have changed much more in the course of their evolutionary history than previously believed. Evidence for this thesis has been provided by new fossils of a ray-like shark, Protospinax annectans, which demonstrate that sharks were already highly evolved in the Late Jurassic.
