The crystal structure of haemoglobin from Atlantic cod

The crystal structure of haemoglobin from Atlantic cod has been solved to 2.54 Å resolution. The structure consists of two tetramers in the crystallographic asymmetric unit. The structure of haemoglobin obtained from one individual cod suggests polymorphism in the tetrameric assembly.

The Spitzer Photo Atlas of Galactic “Train Wrecks”

Five billion years from now, our Milky Way galaxy will collide with the Andromeda galaxy. This will mark a moment of both destruction and creation. The galaxies will lose their separate identities as they merge into one. At the same time, cosmic clouds of gas and dust will smash together, triggering the birth of new stars.

Shark ‘hotspots’ and fishing activities overlap in the North Atlantic Ocean

Sharks aggregate in ‘hotspots’ in the North Atlantic Ocean and are at risk from overfishing by longliner vessels that target the same areas for fishing, a recent study has concluded. Researchers found that the shark and fishing-fleet ranges overlapped by 80% in the North Atlantic and call for international regulation of shark catches to protect at-risk shark populations.

How does drained peatland respond to wildfire?

Wildfires could release up to nine times more stored carbon from drained peatland at high latitudes than from untouched peatland in the same region, according to a recent study. As climate change is expected to both dry out peatland and increase the frequency of wildfires, the results have serious implications for the role of northern peatlands as carbon sinks or sources.

Polar and Atlantic cod share habitat, but not diet

Despite Atlantic cod and haddock extending further into Arctic waters, a new study reveals there is little competition for food between the invaders and native polar cod. However, it is uncertain whether climate change will increase competition between the species as range expansion of the Atlantic species progresses.

Environmental Scenario Planning: what if marine conservation hotspots in NE Atlantic increase under climate change?

Atlantic beaches of Europe reshaped in stormy winter of 2013–2014

Waves hitting Europe’s Atlantic coast during the winter of 2013–2014 were the most powerful in nearly 70 years, reports a new study. They caused significant coastal erosion and the study found examples of beaches which are now several metres lower. The study’s authors say that coastal planners should consider increasingly stormy conditions in the north-east Atlantic, as predicted by some climate change models.

New insights into multi-century phytoplankton decline in North Atlantic predict further decline under climate change

Phytoplankton are essential to marine food webs and fisheries. However, a new study indicates that their levels have declined in the North Atlantic since the beginning of the 19th century. This coincides with weakening ocean-circulation patterns, partly caused by melting ice caps. If the melting continues, the study warns of a dramatic fall in North Atlantic plankton levels that could have cascading effects across marine food webs, reducing the ocean’s ability to absorb carbon and threatening the supply of seafood for humans.

Laboratory-scale wetlands remove toxic veterinary drugs from wastewater

Constructed wetlands can effectively remove veterinary drugs from wastewater, preventing contamination of the environment, research suggests.

Wetland management needs a ‘human-centric’ approach

Increased concerns over fluvial carbon losses from deforested tropical peatlands

Marine protected areas increase survival of Atlantic cod

Marine protected areas (MPAs) are widely used to safeguard marine ecosystems across Europe. This study investigated the effect of a partially protected area (PPA) off the coast of Norway on a population of Atlantic cod (Gadus morhua). The PPA reduced the number of deaths due to fishing, increased survival and stimulated movement to surrounding areas. The authors say that preventing fishing altogether would increase survival even further and recommend no-take zones in areas where populations are severely reduced.

Will any wetlands survive future sea level rise?

Only wetland environments with high sediment input from rivers can keep pace with rising sea levels, according to a new study. However, human activity is destroying wetlands’ natural defences, making their survival increasingly unlikely. The researchers call for sustainable management approaches to protect wetlands under future climate change projections.

Blocking drainage ditches aids peatland restoration

Groundwater extraction for agriculture increases salt levels in Spanish coastal wetland

Around 20% of all species found in a Spanish coastal wetland could be affected by increasingly salty water as seawater intrudes into the groundwater system as a result of groundwater being withdrawn to irrigate crops.

Constructed wetlands help keep farmland soil out of rivers

Small, artificial wetlands can reduce river pollution by trapping soil and nutrients swept off agricultural land by rainfall, a recent study finds. The researchers recommend that they are used as a back-up option to soil management measures also designed to reduce runoff into rivers.

Artificial wetlands on farmland help to prevent soil loss and recapture agricultural by-products

Small field wetlands are a simple and effective way to reduce soil erosion and nutrient pollution, recent research suggests. The authors adapted Norwegian designs for the UK environment and created a series of small rectangular lakes on the edges of agricultural fields. After three years, the wetlands had prevented tonnes of soil from leaving the land, and helped alleviate some of the nutrient run-off that would have affected neighbouring waterways.

Constructed wetlands for removing human pathogens: factors affecting water safety

Constructed wetlands can remove disease-causing bacteria from wastewater, but their performance is highly dependent on the systems they use, a new study shows.

However, further research and improvement of wetland systems is required to produce water that is safe for reuse.

Wetland biodiversity is supported by temporary flooding and sustainable grazing

The preferred habitats of wetland bird species - including 12 that are endangered - have been identified by a new study. From conducting counts at 137 sites across Sweden, it was found that total species richness was highest in sites that had a tendency to flood; wet grassland areas that were grazed as opposed to mowed; and sites that were far from areas of woodland. The authors suggest this research could help determine the most suitable locations for future wetland conservation projects.
