All collected data will be made freely available. The launch of an online crowdsourcing database for seagrass hopes to breathe new life into efforts to conserve the underwater flowering plants, which act as both important habitats for marine species and a major store of carbon dioxide.Patchy mapping of seagrass meadows has hampered efforts to protect the plants (which are distinct from seaweed) from threats such as coastal development, sedimentation, coral farming and sand mining, according to Richard Unsworth, a marine biologist at Swansea University in the U.K. and co-founder of environmental charity Project Seagrass.The group on June 4 launched SeagrassSpotter, a collaborative initiative that allows anyone with a camera to upload images of seagrass sightings and tagged locations from anywhere in the world. The online tool also provides species information to help ordinary users identify the seagrass they find. The platform is accessible via website or mobile app for Android and iOS.“We’re asking people visiting the coast or going out to sea — for diving, fishing, kayaking — to keep their eyes out for seagrass so that they can take a picture [to] upload to our website,” Unsworth told Mongabay. “The more people that get involved the more likely we are to develop a better understanding of the world’s seagrass.”Seagrass meadows are often ignored in marine conservation efforts, but they are important ecosystems for marine animals.

Previous reports suggest that more than 600 species of fish in Southeast Asia alone rely on these meadows for their growth and development. Seagrass beds are also an important home for marine invertebrates, such as sea cucumbers, prawns and crabs.Some seagrass meadows also serve to store large quantities of so-called blue carbon, the carbon dioxide absorbed by the world’s oceans and coastal ecosystems. It’s been estimated that seagrass meadows may be able to store more CO2 in their roots than all the world’s rainforests.The online tool SeagrassSpotter aggregates reported sightings of seagrass ecosystems from around the world to help in the effort to conserve the underwater plants.

Good effort trying to be objective in this article. I would like to give a constructive feedback which could help in clearing things up.1. It is mentioned that planting trees in village common lands will have negative affects socially and ecologically. There is no need to even have to agree or disagree with it, because, you also mentioned the fact that Cauvery Calling aims to plant trees only in the private lands of the farmers. So, plantation in the common lands doesn’t come into the picture.2.I don’t see that the ecologists are totally against this project, but just they they have some concerns, mainly in terms of what species of trees will be planted. And because there was no direct communication between the ecologists and Isha Foundation, it was not possible for them to address the concerns. As you seem to have spoken with an Isha spokesperson, if you could connect the concerned parties, it would be great, because I see that the ecologists are genuinely interested in making sure things are done the right way.May we all come together and make things happen.Rare Amazon bush dogs caught on camera in BoliviaCarrot1 Feba very good iniciative to be fallowed by the ranchers all overSponsored The platform also provides information on seagrass species to help with identification. Image courtesy of SeagrassSpotter.Seagrasses are disappearing at rates that rival those of coral reefs and tropical rainforests, losing as much as 7 percent of their area each year, according to the IUCN. More than 70 species of seagrass worldwide cover a global area estimated at up to 600,000 square kilometers (about 232,000 square miles) — an area larger than the island of Madagascar.“We increasingly know how seagrasses support biodiverse fauna but we know little about how to manage them to be resilient into the future and how to restore these systems once they’ve been lost,” Unsworth said.He pointed to Indonesia as an example of a seagrass hotspot, where the dearth of knowledge about the plants could potentially lead to the extinction of these underwater gardens across the archipelago.Indonesia is widely considered an important country for seagrass conservation. In 1994, researchers estimated the country was home to 30,000 square kilometers (11,600 square miles) of seagrass, perhaps the world’s largest concentration of the plant. But in June 2017, the Indonesian Institute of Sciences (LIPI), a government-funded research agency, put the country’s seagrass cover at just 1,507 square kilometers (582 square miles).“Having worked extensively on seagrass in Indonesia since 2003, I see that seagrass is largely not on the conservation radar,” Unsworth said.“When you visit marine parks and places with seagrass, its conservation is commonly not included or just there as a token inclusion. The focus is always on coral reefs, even though often the majority of the fishing effort is on nearshore shallow seagrass.”At least two studies by researchers in Indonesia have attempted to map seagrass meadows in certain locations, but both noted that nationwide mapping efforts were practically non-existent.A handful of seagrass meadow sightings in Indonesia have been submitted to SeagrassSpotter. Image courtesy of SeagrassSpotter.According to Unsworth, LIPI now runs a seagrass monitoring program, but it’s only on seagrass meadows in marine parks where threats aren’t as prevalent and widespread as in other, unprotected, coastal regions in Indonesia.“Funding for projects by NGOs largely ignores seagrass or when budgets are stretched, they always pull the seagrass component first,” he said. “Having met with fisheries officers, park managers and local government officials over many years, my overwhelming opinion is that seagrass is not considered to be of much importance.”A search of the academic literature on coral reefs versus seagrass in Indonesia reveals that five times as many studies published about the former than the latter in the period between 1970 and 2018, Unsworth said.He also pointed to dataset compiled by the U.N. Environment Programme’s World Conservation Monitoring Centre showing huge gaps where seagrass has been mapped.“The gaps are places where the environmental conditions suggest seagrass should be prevalent,” Unsworth said. “This includes many areas where I personally have observed extensive seagrass, such as Buton, Selayar, Central Sulawesi.”The latest figures from LIPI indicate that only 40 percent of seagrass in Indonesia is considered in healthy condition. Coastal land development, sedimentation, waste pollution, coral aquaculture and sand mining are the top threats to Indonesia’s seagrass.Unsworth and his team of researchers published a report in April that indicates 90 percent of the seagrass meadows they examined in Indonesia had been extensively damaged and degraded over the past five years.“Seagrasses in some parts of Indonesia are very well mapped, but across the nation knowledge is very poor and this comes at an important time given what we know about the losses of seagrass,” he said.Other countries, like Australia, have also reported findings of extensive seagrass meadows in seabeds deeper than 20 meters (66 feet), but “next to no deepwater seagrass has ever been documented in Indonesia,” Unsworth said.“This is probably because no one has ever looked for it,” he said.To date, SeagrassSpotter has collected more than 1,000 records of seagrass around the U.K. and northern Europe. Globally, the group hopes to obtain at least 100,000 records by engaging people from around the world to collect data about seagrass in their locality. All collected data will be freely available to the public.“If people don’t know where seagrass is and why it’s of value,” Unsworth said, “then they won’t take action to preserve it.”Healthy seagrass on the ocean floor.

The brown hyena – prime suspect in theancient whodunnit. (Image: Richard DuToit, Nature Picture Library) Electron microscope scans of fivefossilised human hairs.(Image: Born Animal – Discovery News) Gladysvale has yielded thousands of fossilsof man and beast, with millions more stillin place. (Image: Gladysvale)Janine ErasmusThe World Heritage Cradle of Humankind site has yielded another important archaeological find, with the discovery of what is very probably strands of ancient human hair in a fossilised piece of hyena dung – dating back to around 200 000 years ago.The strands are the oldest examples of their kind, surpassing the previous oldest known specimens of human hair by 191 000 years. The latter were found on a 9 000-year-old Chinchorro mummy from Arica, Chile.The Chinchorro culture was prevalent in northern Chile and southern Peru between 5 000 and 3 000 BC. Mummies from this epoch are the oldest examples of mummified human remains, much older than even the Egyptian mummies. However, the new find makes the hair from the Chinchorro mummies seem positively youthful.The strands were found in a hyena latrine – typically used by a single animal – embedded within a fossilised clump of dung known as a coprolite. Appearing to the untrained eye to be nothing more than a group of round white rocks, the coprolites each measured roughly 2 cm in diameter.The high calcium content in such biological objects, and the calcium-imbued drip from the cave roof, facilitated the fossilisation and preservation of the hairs. After carefully extracting the delicate specimens with tweezers, researchers placed them under an electron microscope. Scans revealed external wavy scale patterns that are characteristic of primates – these, and the size and shape of the hairs suggest that they are human in origin.The hyena species in question is the brown hyena (Parahyaena brunnea), a canny opportunist that derives most of its nourishment from scavenging, although it has been known to occasionally hunt small mammals.Although they consider it most likely that the animal stumbled upon its last meal, scientists have not ruled out the possibility that a hyena attack was the cause of death. Brown hyenas are found in the area still today.Rich source of fossilsThe exciting discovery was made at Gladysvale Cave in Gauteng, located about 45km north-west of Johannesburg. The cave, which sits in the John Nash Nature Reserve within the boundaries of the Cradle of Humankind, has been a prolific source of fossilised specimens since the first fossil, that of a baboon, was found in 1946.The complex consists of three underground caves containing a substantial amount of breccia – that is, a clastic (fragmentary) rock composed of angular gravel-size fragments in a matrix or cementing material. Sediments in the cave date from as ancient as three million years to as recent as 250 years ago.Since 1946, thousands of fossils have been recovered from the Gladysvale deposits, both inside and outside the cave, including rare remains of hominids. The first hominid remains – two teeth of the early human species Australopithecus africanus – were discovered in 1991.The famous fossils of the Taung Child and Mrs Ples are both fine examples of A. africanus. The good news for the scientific community is that there are still millions of ancient bones in place in the cave, waiting to be unearthed.International collaborationPaleoanthropologist Dr Lucinda Backwell of the School of Geosciences at the University of the Witwatersrand headed the study, together with a team of South African and international colleagues from Switzerland and the UK.Their findings are due to be published shortly in the print version of the Journal of Archaeological Science, but for those who can’t wait, the article has been available on the journal’s website since 31 January 2009.The owner of the hair has not yet been established but, said Backwell, the hyena dung falls within the period of existence in Africa of early species of humans such as Homo heidelbergensis. This period, which spans 195 000 to 257 000 years in the past, also saw the emergence of the first anatomically modern humans.“The hairs could belong to either of them or, of course, to a species not yet recognised,” explained Backwell.Although there are no hairs from early human species to use for comparison, and DNA sampling from the hairs was not possible, there is a plethora of coprolite material in the cave. Further analysis of the fossilised dung may well lead to a better understanding of the environment in which our ancestors lived, and their interactions with the creatures around them.Significant findThe hairs are significant in a number of ways. They represent a soft tissue find from a period, said Backwell, which rarely even yields skeletal material.Furthermore, commented biological anthropologist Pat Shipman of Penn State, “The hair is an especially exciting find because it raises the possibility that there are other coprolites with other hairs, which would give us a new and quite accurate means of looking at the composition of ancient animal communities.”Hyenas search for food in their immediate surroundings, she added, so at that time a human lived, or at least died, close to Gladysvale cave.This also raises the possibility that at that time humans were preyed upon or scavenged by hyenas, or that they competed with them for food resources.Do you have queries or comments about this article?

In LP Magazine‘s November-December 2015 issue, Mike Silveira, vice president of loss prevention at CVS Health, discusses how he began his career as a store detective at Ames Department Store. Working his way up the career ladder with Home Depot before moving to CVS gave him a great appreciation for all levels of the organization, which to this day makes him want to stay connected to the field even as he heads the LP function at corporate headquarters.“Despite our very effective field structure, I also think it’s important for me to personally get out in the field regularly to keep close tabs on what’s happening in the stores and what’s happening in the market,” he told James Lee, LPC, LP Magazine’s executive editor. “I’m the kind of leader that likes to be involved, likes to understand the details, and knows the importance of sticking close to the stores.”What advice does Silveira give young people about moving forward in their careers? “I think what’s most important is to have a good work ethic. And that includes the professional life of a driven person balanced with home life,” Silveira said. “There’s a tremendous amount that you need to learn before you take on a leadership role. It’s very important to be patient. Learn as much as you can about the industry – the roles, strategies, techniques, organizational structures, and the business side of the house. Understand budgeting, forecasting, and shrink budgeting for the front of the store as well as for anything specialized the company does, such as the pharmacy in my case and the many facets of the Caremark side of the business.”- Sponsor – He added, “I think being innovative and reinventing yourself every years is also a key component. Being an outstanding leader, who is fearless and willing to take risks, is also an extremely important attribute that helps you succeed in this industry.”Read more of Lee’s interview with Silveira as they take a close look at the challenges and opportunities inside the drug-store retail segment.
