Antibiotic-resistant bacterial infections are on the rise and pose a serious threat to society. The influence of genetic resistance mechanisms on antibiotic therapy is well described. However, other factors, such as epigenetic resistance or the impact of the environment on antibiotic therapy, are less well understood. Here, we describe and characterize a mechanism of noninherited antibiotic resistance that enables the survival and outgrowth of genetically susceptible bacteria during antibiotic therapy.

Despite the rapid increase in the use of unmanned aerial vehicles (UAVs) in marine mammal research, knowledge of the effects of UAVs on study animals is very limited. We recorded the in-air and in-water noise from two commonly used multi-rotor UAVs, the SwellPro Splashdrone and the DJI Inspire 1 Pro, to assess the potential for negative noise effects of UAV use. The Splashdrone and Inspire UAVs produced broad-band in-air source levels of 80 dB re 20 μPa and 81 dB re 20 μPa (rms), with fundamental frequencies centered at 60 Hz and 150 Hz.

This article aims to examine the use pattern and potentiality of livestock farming in the Uttarakhand Himalaya, India. We collected and compared data on livestock population and production in 13 districts of Uttarakhand (2001–14) and noted that number of milching livestock, improved hen and milk production increased during the period. Meanwhile, population of sheep, goat, lamb and indigenous hen has decreased. The study reveals that livestock farming, including cattle, milching animals, goat and sheep has high potential in livelihood sustainability.

Changes in temperature and rainfall patterns have introduced numerous problems across India, particularly among the poor and those heavily dependent on agriculture and forest for livelihood. This article examines the perception of the Maltos, a tribal community living in Sahibganj district, Jharkhand, about climate change, its impacts, and the coping mechanisms it has adopted.

Welcoming the debate on the assumptions underpinning water resource monitoring in India triggered by the Mihir Shah Committee report, the authors suggest that the proposed National Water Commission should focus on providing integrated data and science to help water managers and policymakers, avoiding getting directly involved in planning or regulation.

This critique assesses if the National Water Framework Bill 2016 and the Mihir Shah Committee report are truly interdisciplinary and based on the principles of integrated water systems governance. The question still remains whether the recommendations are enough to bridge existing gaps and address future challenges in water governance.

The Aadhaar-linked Direct Benefit Transfer scheme for reducing leakages in Liquified Petroleum Gas (LPG) subsidies has been widely advertised as a phenomenal success and has been used to promote Aadhaar and DBT in other spheres by prominent government officials. However, an analyses of various studies and data shows that the government’s tall claims of savings cannot be confirmed and leaves much to be questioned.

Impacts of climate change on individual species are increasingly well documented, but we lack understanding of how these effects propagate through ecological communities. Here we combine species distribution models with ecological network analyses to test potential impacts of climate change on >700 plant and animal species in pollination and seed-dispersal networks from central Europe. We discover that animal species that interact with a low diversity of plant species have narrow climatic niches and are most vulnerable to climate change.

rVSV-ZEBOV is a recombinant, replication competent vesicular stomatitis virus-based candidate vaccine expressing a surface glycoprotein of Zaire Ebolavirus. We tested the effect of rVSV-ZEBOV in preventing Ebola virus disease in contacts and contacts of contacts of recently confirmed cases in Guinea, west Africa.

In this study we evaluated CO2 emissions during composting of green wastes with clay and/or biochar in the presence and absence of worms (species of the genus Eisenia), as well as the effect of those amendments on carbon mineralization after application to soil.
