Saving endangered species: New AI method counts manatee clusters in real time      (via sciencedaily.com)     Original source 

Accurately counting manatee aggregations within a region is crucial yet challenging. Harnessing the power of AI, researchers are using a deep learning-based crowd counting approach to automatically count the number of manatees in a designated region, using images captured from CCTV cameras, which are readily available, as input. The pioneering study not only addresses the technical challenges of counting in complex outdoor environments but also offers potential ways to aid endangered species.

Aquatic insects in restored streams need more rocks to lay their eggs      (via sciencedaily.com)     Original source 

Likening it to providing more runways at busy airports, researchers at North Carolina State University found in a new study that adding protruding rocks to restored streams can help attract female aquatic insects that lay their eggs on the rock bottoms or sides.

National policy aimed at reducing U.S. greenhouse gases also would improve water quality      (via sciencedaily.com)     Original source 

A climate policy that raises the price of carbon-intensive products across the entire U.S. economy would yield a side benefit of reducing nitrate groundwater contamination throughout the Mississippi River Basin. The Gulf of Mexico, an important U.S. fishery, also would see modest benefits from the nitrate reductions.

Zapping manure with special electrode promises an efficient method to produce fertilizers, other chemicals      (via sciencedaily.com)     Original source 

An interdisciplinary team has developed a new technique that could help farmers extract useful nutrients such as ammonia and potassium from livestock manure to efficiently make fertilizer and other useful chemical products. While the strategy still needs to be scaled up beyond a proof-of-concept stage, the group's preliminary analyses show it could offer considerable benefits by cutting water and air pollution while simultaneously creating products that farmers could use or sell.

New study sheds light on how much methane is produced from Arctic lakes and wetlands      (via sciencedaily.com)     Original source 

New study looked at lakes in the Arctic, including those at Alaska's Yukon Flats National Wildlife Refuge, to shed light on how much methane is produced from Arctic lakes and wetlands. Small unmapped lakes in the Arctic are far less abundant than previously thought, greatly reducing the cumulative methane emissions they were thought to contribute to Earth's atmosphere.

Extreme rainfall increases ag nutrient runoff, conservation strategies can help      (via sciencedaily.com)     Original source 

Nutrient runoff from agricultural production is a significant source of water pollution in the U.S., and climate change that produces extreme weather events is likely to exacerbate the problem. A new study looks at how extreme rainfall impacts runoff and suggests possible mitigation strategies.

New geophysical technique enhances imaging of fluid-filled rocks finding connections with microearthquakes      (via sciencedaily.com)     Original source 

Scientists have recently introduced a new method called ambient noise differential adjoint tomography, which allows researchers to visualise rocks with fluids better, leading to potential advancements in the discovery of water and oil resources, as well as applications in urban geologic hazard and early warning systems for tsunamis and the understanding of the water cycle.

Have researchers found the missing link that explains the mysterious phenomenon known as fairy circles?      (via sciencedaily.com)     Original source 

Fairy circles, a nearly hexagonal pattern of bare-soil circular gaps in grasslands, initially observed in Namibia and later in other parts of the world, have fascinated and baffled scientists for years. New research suggests that all theories to date have overlooked the coupling between two robust mechanisms essential for understanding ecosystem response: phenotypic plasticity at the level of a single plant, and spatial self-organization in vegetation patterns at the level of a plant population.

Polyethylene waste could be a thing of the past      (via sciencedaily.com)     Original source 

Experts have developed a way of using polyethylene waste (PE) as a feedstock and converted it into valuable chemicals, via light-driven photocatalysis. PE is the most widely used plastic in the world including for daily food packaging, shopping bags and reagent bottles, and the researchers say that while recycling of PE is still in early development, it could be an untapped resource for re-use.

Adapting to hypoxia: Zooplankton influence the efficiency of the biological carbon pump in the Humboldt Current off Peru      (via sciencedaily.com)     Original source 

Marine organisms play a crucial role in the global carbon cycle. Phytoplankton absorb carbon dioxide from the atmosphere and sequester it in organic matter that sinks to the deep ocean where it can be stored for long periods of time. Until now, this process -- the biological carbon pump -- was thought to be particularly efficient in oxygen-poor areas. A new study suggests that the influence of certain zooplankton species on the biological carbon pump has been underestimated.

Sister climate cities, utility data predict future water, electricity demands      (via sciencedaily.com)     Original source 

Modern-day Ciudad Mante, Mexico, could help Tampa, Florida, plan for shifting water and electricity demands due to climate change, according to an international team of researchers. Researchers used utilities data and climate analogs -- contemporary cities with climates close to what other cities are predicted to experience in the future -- to assess how climate change may impact residential water and electricity use across 46 cities in the United States.

Researchers develop grassroots framework for managing environmental commons      (via sciencedaily.com)     Original source 

A team of sustainability scientists recently announced that they have developed a community-based framework, founded on extensive local and traditional knowledge, to help assess and respond to the kinds of ecological threats that are widely dispersed across a varied landscape and whose solutions are not immediately obvious. The framework, which was developed to address watershed issues in Honduras's Lake Yojoa, is widely applicable to a broad range of threats facing ecological commons wherever they may occur around the world.

Harvesting water from air with solar power      (via sciencedaily.com)     Original source 

Researchers have developed a promising new solar-powered atmospheric water harvesting technology that could help provide enough drinking water for people to survive in difficult, dryland areas: They synthesized a super hygroscopic gel capable of absorbing and retaining an unparalleled amount of water. One kilogram of dry gel could adsorb 1.18 kilograms of water in arid atmospheric environments and up to 6.4 kilograms in humid atmospheric environments. This hygroscopic gel was simple and inexpensive to prepare and would consequently be suitable for large-scale preparation.
