Ecosystem services make human life possible by, for example, providing nutritious food and clean water, regulating disease and climate, supporting the pollination of crops and soil formation, and providing recreational, cultural and spiritual benefits. In 2014, the value of ecosystem services was estimated at a staggering US$ 125 trillion.  Ecosystem services, provided by biodiversity, are fundamental to food production and [...]

The project’s key objective was to demonstrate an innovative integrated ecosystem and water resources management that will improve the environmental conditions in the Baiyangdian Basin in Hebei province, southwest of Beijing. It focused on the need to conserve Baiyangdian Lake—one of the most important and vulnerable ecosystems in the People’s Republic of China (PRC). It would also contribute to achieving the goals of the Baoding municipality’s Eleventh Five-Year Environmental Protection Plan.

Biological nitrogen fixation can be an important source of nitrogen in tropical forests that serve as a major CO₂ sink. Extensive deforestation of the Amazon is known to influence microbial communities and the biogeochemical cycles they mediate. However, it is unknown how diazotrophs (nitrogen-fixing microorganisms) respond to deforestation and subsequent ecosystem conversion to agriculture, as well as whether they can recover in secondary forests that are established after agriculture is abandoned. To address these knowledge gaps, we combined a spatially explicit sampling approach with high-throughput sequencing of nifH genes. The main objectives were to assess the functional distance decay relationship of the diazotrophic bacterial community in a tropical forest ecosystem and to quantify the roles of various factors that drive the observed changes in the diazotrophic community structure. We observed an increase in local diazotrophic diversity (α-diversity) with a decrease in community turnover (β-diversity), associated with a shift in diazotrophic community structure as a result of the forest-to-pasture conversion. Both diazotrophic community turnover and structure showed signs of recovery in secondary forests. Changes in the diazotrophic community were primarily driven by the change in land use rather than differences in geochemical characteristics or geographic distances. The diazotroph communities in secondary forests resembled those in primary forests, suggesting that at least partial recovery of diazotrophs is possible following agricultural abandonment.

IMPORTANCE The Amazon region is a major tropical forest region that is being deforested at an alarming rate to create space for cattle ranching and agriculture. Diazotrophs (nitrogen-fixing microorganisms) play an important role in supplying soil N for plant growth in tropical forests. It is unknown how diazotrophs respond to deforestation and whether they can recover in secondary forests that establish after agriculture is abandoned. Using high-throughput sequencing of nifH genes, we characterized the response of diazotrophs’ β-diversity and identified major drivers of changes in diazotrophs from forest-to-pasture and pasture-to-secondary-forest conversions. Studying the impact of land use change on diazotrophs is important for a better understanding of the impact of deforestation on tropical forest ecosystem functioning, and our results on the potential recovery of diazotrophs in secondary forests imply the possible restoration of ecosystem functions in secondary forests.

Scientists have named a new marine ecological community, the Plastisphere, comprised of, you guessed it, plastic -- and all the organisms that now call ocean plastic home.

The routing ecosystem around React and React Native is quite different. One is characterized by a strong incumbent, and the other is plagued by rapid change.

React JS

No question about it, React Router (ReactTraining/react-router) is king here. They have the benefit of several years of active development, along with an active community submitting PR’s, fixes, etc. Supplement that with myriad tutorials and how-to’s and you end up with a well-supported, stable product. To be fair, React Router has suffered some major API upsets, and is nearly the poster-child for javascript fatigue but the maintainers have declared their lasting support for a few specific versions, which means you can plop down with V3 and be good to go for the next 12 to 24 months.

React Native

Ok, this is where things start to get really, really crazy. The most important thing to keep in mind is that the React Native team has produced three navigation helpers: NavigatorIOS, Navigator, and NavigatorExperimental.

• NavigatorIOS was quickly deprecated, as it was supported only by (you guessed it) IOS.
• Navigator is the currently endorsed solution for navigation, at least if you are following the official docs. However, its about to be upset by-
• NavigationExperimental. This is an updated navigator that has learned some lessons from Navigator, and has some solid integration with Redux. ‘Navigator’ is (or was!) sleighted to be deprecated in favor of NavigationExperimental at some point.

Already you have three ‘official’ navigators supported by the React Native team. The big issue with all three of these is that they are somewhat lightweight and don’t include a lot of common navigation situations out of the box, like sidebars, tab bars, headers, etc. To solve that, the community has introduced…

• React Native Router Flux (aksonov/react-native-router-flux). My personal favorite, this is router is based upon NavigationExperimental. You can imagine that the authors looked at NavigationExperimental, realized that everyone would be writing the same wrapper code around it, and so created this project.
• React Native Router (t4t5/react-native-router). Haven’t used it, but it is colossally popular.
• React Router Native (jmurzy/react-router-native). Strives for API conformity with React Router (the above mentioned one). The great approach here is that they bring in the concept of a URL in native apps, where one doesn’t otherwise exist. This is a great approach that simplifies a lot of common routing situations. Of course, there’s one more big solution that is supposedly going to become the standard:
• React Navigation (react-community/react-navigation). Seen as a solution that will soon be ‘official’ in the community, it is intended to replaced NavigationExperimental. This package is still in active development, so I expect at least a bit of API upset over the coming months. If you want to use official solutions, go with this, if you want a tried and true solution, go with React Native Router Flux.

An ecosystem assessment is a social process through which the findings of science concerning the causes of ecosystem change, their consequences for human well-bring, and the management and policy options are evaluated. The main objective of the paper is to draw insights from experience in the UK, Japan, Spain and Portugal of the added value to policy making of undertaking national level ecosystem assessments.

Should we worry more about quantum decryption in the future or the past, how salt's role as a micronutrient may effect the global carbon cycle, and a daily news roundup.

When Indonesia’s Mount Toba blew its top some 74,000 years ago, an apocalyptic scenario ensued: Tons of ash and debris entered the atmosphere, coating the planet in ash for 2 weeks straight and sending global temperatures plummeting. Despite the worldwide destruction, humans survived. Sarah Crespi talks with Online News Editor Catherine Matacic about how life after Toba was even possible—were humans decimated, or did they rally in the face of a suddenly extra hostile planet? Next, Julia Buck of the University of California, Santa Barbara, joins Sarah to discuss her Science commentary piece on landscapes of disgust. You may have heard of a landscape of fear—how a predator can influence an ecosystem not just by eating its prey, but also by introducing fear into the system, changing the behavior of many organisms. Buck and colleagues write about how disgust can operate in a similar way: Animals protect themselves from parasites and infection by avoiding disgusting things such as dead animals of the same species or those with disease.
