Understanding microbe communities could improve wetland wastewater treatment systems

COLUMBIA, Mo. – Wetlands serve as the Earth’s kidneys. They filter and clean people’s water supplies while serving as important habitat for many species, including iconic species like cattails, cranes and alligators. Conventional ecosystem health assessments have focused on populations of these larger species. However, the tiny, unseen creatures in the wetlands provided crucial indicators of the ecosystems’ health in a study by University of Missouri Associate Professor of Engineering Zhiqiang Hu and his team. Using analysis of the microbiological health of wetlands is cheaper and faster than traditional assessments, and could lead to improvements in harnessing natural processes to filter humans’ wastewater.

“During road and building construction, engineers must sacrifice wetlands to development, but laws dictate that these lost wetlands be compensated for by establishing a wetland somewhere else,” said Hu. “Our research could be applied to both monitor the success of these compensation wetlands and guide conservationists in inoculating new engineered ecosystems with the correct types of microorganisms.” (more…)

Size of Lunch Dictates Force of Crunch

Even in the same animal, not all bites are the same. A new study finds that because the force in a muscle depends on how much it is stretched, an animal’s bite force depends on the size of what it is biting. The finding has direct implications for ecology and evolution.

PROVIDENCE, R.I. [Brown University] — Many animals prefer food — snails, nuts, etc. — that must be cracked and crushed. Scientists have measured the maximum force of their impressive bites before, but a new study introduces a significant subtlety: bite force depends not only on the size and strength of the eater, but also the size of the eatee. That insight has important implications in the lives of predators and prey. (more…)

Invasive species among marine science subjects in Cayman Islands study abroad program

With a spiky fringe of venomous barbs and bold brown-and-white stripes, the exotic lionfish invaded Florida waters several decades ago and expanded its range widely from the Caribbean to New York. Native to the Indo-Pacific, the invasive species has no natural predators in this part of the world and readily feasts on small fish and shrimp.

UD students have the opportunity to observe these intruders — up-close and underwater — in a new study abroad program offered in the Cayman Islands through the School of Marine Science and Policy (SMSP). (more…)

Study Finds Severe Climate Jeopardizing Amazon Forest

PASADENA, Calif. – An area of the Amazon rainforest twice the size of California continues to suffer from the effects of a megadrought that began in 2005, finds a new NASA-led study. These results, together with observed recurrences of droughts every few years and associated damage to the forests in southern and western Amazonia in the past decade, suggest these rainforests may be showing the first signs of potential large-scale degradation due to climate change.

An international research team led by Sassan Saatchi of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., analyzed more than a decade of satellite microwave radar data collected between 2000 and 2009 over Amazonia. The observations included measurements of rainfall from NASA’s Tropical Rainfall Measuring Mission and measurements of the moisture content and structure of the forest canopy (top layer) from the Seawinds scatterometer on NASA’s QuikScat spacecraft.

Cloud computing enhances control of “Internet of Things” in the home to help manage heating, lighting, security and more via multiple user interfaces including gestures and voice recognition

LAS VEGAS, CES – 08 Jan 2013: IBM, STMicroelectronics and Shaspa today announced a collaboration to tap cloud and mobile computing for manufacturers and service providers to provide innovative ways for consumers to manage and interact with their homes’ functions and entertainment systems using multiple user interfaces such as voice recognition and physical gestures for a smarter home.

A “smart home” brings networking functions together, creating a gateway that connects a television, computer or mobile device with smart meters, lights, appliances, plugs and sensors within the home as well as services from outside. Parks Associates forecasts that more than 8 billion devices will be connected on the home network by year-end 2015.[1] (more…)

Asteroid that Killed the Dinosaurs also Wiped out the ‘Obamadon’

The asteroid collision widely thought to have killed the dinosaurs also led to extreme devastation among snake and lizard species, according to new research — including the extinction of a newly identified lizard Yale and Harvard scientists have named Obamadon gracilis.

“The asteroid event is typically thought of as affecting the dinosaurs primarily,” said Nicholas R. Longrich, a postdoctoral associate with Yale’s Department of Geology and Geophysics and lead author of the study. “But it basically cut this broad swath across the entire ecosystem, taking out everything. Snakes and lizards were hit extremely hard.” (more…)

Blanket Bogs Need Protection from Climate Change

Blanket bogs, which provide vital habitats for a unique range of plants, birds, small mammals, reptiles and amphibians, are at risk of declining as a result of climate change.

Research by the Universities of Exeter and Bristol in the UK and Macquarie University in Australia, published in the journal Nature Climate Change, shows for the first time how rising temperatures will threaten these sensitive ecosystems.

The study highlights the urgency of developing a plan to protect these important habitats.

Found in wet, coastal areas of high latitude regions, blanket bogs cover around 700,000 hectares of land in the UK, much of it designated as a Site of Special Scientific Interest (SSSI). Blanket bogs are found in the north and west of the UK, extending from Devon in the south to Shetland in the north, and it has been estimated that 10 to15 per cent of the world’s blanket bog occurs in Britain. As well as being crucial in supporting wildlife, blanket bogs also capture and store large amounts of carbon, helping to mitigate against climate change, and reduce the risk of flooding, by slowing down water flow. With some blanket peat being over 9,000 years old, they also hold historically-significant archaeological material. (more…)
