Bruce Parry returns form the rainforest with the secret to love, peace and harmony

Award winning documentary maker Bruce Parry has raised the money to direct his first independent film. He wants to tell the story of the Penan indigenous tribe – so we can learn the secret of interconnected living. But should we believe him, asks BRENDAN MONTAGUE in Part II of this exclusive interview.

Circles in the sand reveal boating damage to marine biodiversity

The findings of a study by Swansea and Cardiff University scientists highlights the need for boating activities along the UKs beautiful coastlines to be conducted in a more environmentally friendly manner.

Seagrass meadows are an important marine habitat in support of our fisheries and commonly reside in shallow sheltered embayments typical of the locations that provide an attractive option for mooring boats. Research led by scientists at Swansea University provides evidence for how swinging boat moorings have damaged seagrass meadows throughout the UK (and globally) and create lifeless halos within the seagrass. The creation of these halos devoid of seagrass fragments the meadow and reduces its support for important marine biodiversity.

On International Day, UN spotlights threatened coastal mangrove ecosystems

Coastal mangroves are among the most imperiled ecosystems on earth, with current estimates indicating that up to 67 per cent have been lost to date – according to the United Nations science wing.

“The stakes are high, because mangrove ecosystems provide benefits and services that are essential for life,” said Irina Bokova, Director-General of the UN Educational, Scientific and Cultural Organization (UNESCO) in a message on the International Day for the Conservation of the Mangrove Ecosystem.

Atomic Movies May Help Explain Why Perovskite Solar Cells Are More Efficient

In recent years, perovskites have taken the solar cell industry by storm. They are cheap, easy to produce and very flexible in their applications. Their efficiency at converting light into electricity has grown faster than that of any other material – from under four percent in 2009 to over 20 percent in 2017 – and some experts believe that perovskites could eventually outperform the most common solar cell material, silicon. But despite their popularity, researchers don’t know why perovskites are so efficient.

Now experiments with a powerful “electron camera” at the Department of Energy’s SLAC National Accelerator Laboratory have discovered that light whirls atoms around in perovskites, potentially explaining the high efficiency of these next-generation solar cell materials and providing clues for making better ones.

Seawalls: Ecological Effects Of Coastal Armoring In Soft Sediment Environments

Ocean Leadership ~

For nearly a century, the O’Shaughnessy seawall has held back the sand and seas of San Francisco’s Ocean Beach. At work even longer: the Galveston seawall, built after America’s deadliest hurricane in 1900 killed thousands in Texas.

(From ScienceDaily / by Julie Cohen) — These are just two examples of how America’s coasts — particularly those with large urban populations — have been armored with humanmade structures.

These structures essentially draw a line in the sand that constrains the ability of the shoreline to respond to changes in sea level and other dynamic coastal processes. While the resulting ecological effects have been studied more in recent years, the research largely has been conducted in specific settings, making it difficult to generalize these effects across ecosystems and structure types.

A new study by a team of UC Santa Barbara marine scientists and colleagues from three coastal sites in the National Science Foundation’s Long-Term Ecological Research (LTER) network provides a key first step toward generalizing ecological responses to armoring across the wide diversity of coastal settings where these structures are used. The team’s findings appear online and will be published this fall in a special issue of the journal Estuaries and Coasts, “Impacts of Coastal Land Use and Shoreline Armoring on Estuarine Ecosystems.”

Comparing Notes

The type of armoring structure varies widely with the environmental setting, ranging from massive seawalls and revetments along the wave-exposed open coast to smaller bulkheads and humanmade oyster reefs in tidal marshes and estuaries. “The size and shape of these humanmade structures often result in the loss of intertidal habitats,” said lead author Jenifer Dugan, a research biologist at UCSB’s Marine Science Institute. “The extent of that loss is a function of environmental setting, structure type and how far seaward and along the shore the structure extends.”

Scientists from three very different LTER programs were already working on the ecological impact of coastal armoring at their respective sites. At the Santa Barbara Coastal LTER, studies of the effects of seawalls on open coast beaches had revealed significant ecological impacts extending up to birds. The Georgia Coastal Ecosystems (GCE) project conducted studies of the effects of small-scale armoring in salt marshes. Studies at the Virginia Coast Reserve LTER focused on the use of constructed oyster reefs and living shorelines as coastal protection strategies.

“What was novel about this cross-site collaboration was putting these site-specific studies into perspective by making comparisons across a broad range of habitats,” said co-author Merryl Alber, a marine science professor at the University of Georgia and principal investigator of the GCE LTER project.

The collaborative study synthesizes the findings of existing literature examining different types of armoring across a variety of soft sediment ecosystems. The scientists used that data to evaluate a new conceptual model they created during two LTER cross-site workshops.

Canada top court rules for aboriginals on seismic testing permits

OTTAWA (Reuters) – Canada’s top court on Wednesday handed aboriginals a partial victory on the need to be consulted on resource projects, throwing out permits to conduct seismic testing for oil and gas in the north but dismissing a separate attempt to quash changes to an Enbridge Inc pipeline.
