Rested elephants make more babies
New study shows rested mother elephants produce longer-lived offspring Unique dataset from 1948-2000 spanning five generations of elephants Baby elephants have a greater chance of survival if they are born at certain times of the year, according to experts from the University of Sheffield. Elephants live in a seasonal environment, but unlike a lot of species do not have a single breeding season.

Jurassic jaws: how ancient crocodiles flourished during the age of the dinosaurs
New research has revealed the hidden past of crocodiles, showing for the first time how these fierce reptiles evolved and survived in a dinosaur dominated world. While most modern crocodiles live in freshwater habitats and feed on mammals and fish, their ancient relatives were extremely diverse - with some built for running around like dogs on land and others adapting to life in the open ocean, imitating the feeding behaviour of today's killer whales.

Stay healthy during pregnancy to keep lead levels low
New research from the Children of the 90s study at the University of Bristol shows that mothers who drank alcohol and coffee, smoked and had a coal fire in their home during pregnancy were likely to have higher levels of lead in their blood than women who didn't. Dietary calcium and iron seemed to have a protective effect.

Moss growth in Antarctica linked to climate change
Increases in temperature on the Antarctic Peninsula during the latter part of the 20th century were accompanied by an acceleration in moss growth, scientists have learned. Writing in the journal Current Biology they describe the activity as unprecedented in the last 150 years.

Mega-canyon discovered beneath Greenland ice sheet
Mega-canyon discovered beneath Greenland ice sheet
A previously unknown canyon hidden beneath two kilometres of ice covering Greenland has been discovered by a group of scientists, led by a team from the University of Bristol. The canyon is at least 750km long and in places as much as 800m deep and is on the same scale as parts of the Grand Canyon in Arizona, USA.

New research offers insight into marine life’s ability to adapt to climate change
A study into marine life around an underwater volcanic vent in the Mediterranean, might hold the key to understanding how some species will be able to survive in increasingly acidic sea water should anthropogenic climate change continue. Researchers have discovered that some species of polychaete worms are able to modify their metabolic rates to better cope with and thrive in waters high in carbon dioxide (CO2), which is otherwise poisonous to other, often closely-related species.

Significant levels of iron found in South Atlantic ocean
Significant levels of iron found in South Atlantic ocean
Research by the University of Liverpool has found significant levels of iron and other micronutrients flowing from a hydrothermal vent in the South Atlantic ocean. A team of scientists took samples from a range of depths as they travelled across the South Atlantic from Brazil to Namibia.  Analysis of the samples revealed a distinct plume rich in iron and micronutrients above the mid-Atlantic ridge stretching for more than 1000km.

Plants can change greenhouse gas emissions after warming
Plants can change greenhouse gas emissions after warming
19 Aug 2013 Different moorland plants, particularly heather and cotton grass, can strongly influence climate warming effects on greenhouse gas emissions, researchers from Lancaster University, The University of Manchester and the Centre for Ecology & Hydrology have discovered. The findings, published this week in leading journal Ecology Letters, show valuable carbon stores, which lie deep below peaty moorlands, are at risk from changes in climate and from land management techniques that alter plant diversity.

Soil biodiversity crucial to land management and response to climate change
13 Aug 2013 Research by scientists at The University of Manchester shows maintaining healthy soil biodiversity can play an important role in optimising land management programmes to reap benefits from the living soil. The findings, published in the latest edition of the journal PNAS, extend the understanding about the factors that regulate soil biodiversity.

Melting water’s lubricating effect on glaciers has only ’minor’ role in future sea-level rise
Concerns that melting water would speed up the decline of Greenland's ice sheet have been allayed by new research which shows the lubricating effect of water beneath glaciers will not significantly add to sea-level rise. Scientists had feared that melt-water which trickles down through the ice could dramatically speed up the movement of glaciers as it acts as a lubricant between the ice and the ground it moves over.

Global investigation reveals true scale of ocean warming
Warming oceans are causing marine species to change breeding times and shift homes with expected substantial consequences for the broader marine landscape, according to a new global study. The three-year research project, funded by the National Centre for Ecological Analysis and Synthesis in California, has shown widespread systemic shifts in measures such as distribution of species and phenology – the timing of nature’s calendar – on a scale comparable to or greater than those observed on land.

Climate forecasts shown to warn of crop failures
The research showed that in about one-third of global cropland, temperature and soil moisture has a strong relationship to the yield of wheat and rice at harvest. And, for those two key crops, the model could predict crop failures three months in advance for about 20 per cent of global cropland, according to the study, published on 21 July .

New study indicates need for continuous satellite monitoring of ice sheets to better predict sea-level rise
The length of the satellite record for the Greenland and Antarctic ice sheets is currently too short to tell if the recently reported speed-up of ice loss will be sustained in the future or if it results from natural processes, according to a new study led by Dr Bert Wouters from the University of Bristol.

Solar tsunami used to measure Sun's magnetic field
Solar tsunami used to measure Sun’s magnetic field
A solar tsunami observed by NASA's Solar Dynamics Observatory (SDO) and the Japanese Hinode spacecraft has been used to provide the first accurate estimates of the Sun's magnetic field. Solar tsunamis are produced by enormous explosions in the Sun's atmosphere called coronal mass ejections (CMEs). As the CME travels out into space, the tsunami travels across the Sun at speeds of up to 1000 kilometres per second.

How greenhouse gases affect ocean's foodchain
How greenhouse gases affect ocean’s foodchain
Research by the University of Liverpool has found that climate change is affecting the tiny bacteria - cyanobacteria -  that form the foundation of the ocean's food chain. The study found that rising temperatures and levels of atmospheric carbon dioxide is leading to certain strains of nitrogen-fixing cyanobacteria being eliminated.

New research suggests economic stagnation is no excuse for climate inaction
Policymakers should be paying more, rather than less, attention to tackling climate change in economically tough times, a new study suggests. As economies have stagnated major emitters of CO2 seem unwilling to accept binding emissions reduction targets. But findings, published this week in Nature Climate Change , show the social cost of carbon dioxide is higher in a low economic growth world.

Bat maps: The conservation crusade
Conservation efforts have taken an important step forward, thanks to observations of bats - creatures that make up a quarter of all of the UK's native mammal species. In a paper published today, researchers at the University of Leeds describe how they recorded the echolocation calls of more than 15,000 bats during 120 walks in the Lake District to create maps that show the suitability of areas for bat habitation.

Boat noise stops fish finding home
Boat noise disrupts orientation behaviour in larval coral reef fish, according to new research from the Universities of Bristol, Exeter and Liège. Reef fish are normally attracted by reef sound but the study, conducted in French Polynesia, found that fish are more likely to swim away from recordings of reefs when boat noise is added.
