Temperature, humidity may drive future transmission of parasitic worm infections      (via sciencedaily.com)     Original source 

Studies on climate and infectious disease typically focus on temperature's role on disease transmission. However, an international team found that both temperature and humidity contribute to future trends in the transmission of parasitic worm infections.

Reforestation schemes are not enough to recover the carbon created by harvesting wood      (via sciencedaily.com)     Original source 

Forests have a critical role to play in capturing and storing carbon from the Earth's atmosphere -- but some models exaggerate their carbon removal potential by almost three-fold, according to a leading professor of forest economics.

Birds and bee lessons as Pacific field trips also solve 'Michener's mystery'      (via sciencedaily.com)     Original source 

Eight new Pacific bee species and new insights into Fijian bird behaviour on Viti Levu Island have been described in new scientific studies. The research highlights the potential for species discovery, ecological and conservation knowledge and cultural engagement from Asia-Pacific research collaborations.

Global warming increases the diversity of active soil bacteria      (via sciencedaily.com)     Original source 

Warmer soils harbor a greater diversity of active microbes, according to a new study. The study represents a significant shift in our understanding of how microbial activity in the soil influences the global carbon cycle and possible feedback mechanisms on the climate. Until now, scientists have assumed that higher soil temperatures accelerate the growth of microbes, thus increasing the release of carbon into the atmosphere. However, this increased release of carbon is actually caused by the activation of previously dormant bacteria.

Altering the circadian clock adapts barley to short growing seasons      (via sciencedaily.com)     Original source 

To ensure that plants flower at the right time of year, they possess an internal clock, which enables them to measure the amount of daylight during a day. Biologists now describe that the mutation of a specific gene makes the flowering time of barley almost entirely independent of day length. This mutation can be useful for breeding varieties adapted to altered climatic conditions with relatively mild winters and hot, dry summers.

Snakes do it faster, better: How a group of scaly, legless lizards hit the evolutionary jackpot      (via sciencedaily.com)     Original source 

More than 100 million years ago, the ancestors of the first snakes were small lizards that lived alongside other small, nondescript lizards in the shadow of the dinosaurs.

Cooler, wetter parts of Pacific Northwest likely to see more fires, new simulations predict      (via sciencedaily.com)     Original source 

Forests in the coolest, wettest parts of the western Pacific Northwest are likely to see the biggest increases in burn probability, fire size and number of blazes as the climate continues to get warmer and drier.

Carbon emissions from the destruction of mangrove forests predicted to increase by 50,000% by the end of the century      (via sciencedaily.com)     Original source 

The annual rate of carbon emissions due to the degradation of carbon stocks in mangrove forests is predicted to rise by nearly 50,000% by the end of the century, according to a new study. Mangroves in regions such as southern India, southeastern China, Singapore and eastern Australia are particularly affected.

Mice surprise: Researchers discover new native species      (via sciencedaily.com)     Original source 

Australia can lay claim to two new species of native rodent thanks to a new study. The aptly named delicate mouse was previously thought to be a single species spanning a massive stretch of the country from the Pilbara in Western Australia, across parts of the Northern Territory and through Queensland down to the New South Wales border. We now know there are three distinct species.

Biggest Holocene volcano eruption found by seabed survey      (via sciencedaily.com)     Original source 

A detailed survey of the volcanic underwater deposits around the Kikai caldera in Japan clarified the deposition mechanisms as well as the event's magnitude. As a result, the research team found that the event 7,300 years ago was the largest volcanic eruption in the Holocene by far.

Increasingly similar or different? Centuries-long analysis suggests biodiversity is differentiating and homogenizing to a comparable extent      (via sciencedaily.com)     Original source 

The tendency of communities and the species within them to become more similar or more distinct across landscapes -- biotic homogenization and differentiation -- are approximately balanced, according to a new study. This analysis is the first of its kind to provide a comprehensive assessment of how local and regional biodiversity changes combine across landscapes over centuries.

Why are fish getting smaller as waters warm? It's not their gills      (via sciencedaily.com)     Original source 

A collaborative team of scientists recently found that there is no physiological evidence supporting a leading theory -- which involves the surface area of fish gills -- as to why many fish species are 'shrinking' as waters grow warmer due to climate change. Known as the Gill Oxygen Limitation (GOL) theory, it has been proposed as the universal mechanism explaining fish size and has been used in some predictions of future global fisheries yields. However, the researchers conducted a series of long-term experiments on brook trout and found that, though increased temperatures do lead to significantly decreased body size, gill surface area did not explain the change.

The cultural evolution of collective property rights      (via sciencedaily.com)     Original source 

Common pool resources comprise around 65 percent of Earth's surface and vast tracts of the ocean. While examples of successful governance of these resources exist, the circumstances and mechanisms behind their development have remained unclear. Researchers have developed a simulation model to examine the emergence, stability and temporal dynamics of collective property rights.
