Lives of others

BEYOND USUAL SUSPECTS A case for neglected species in wildlife research and conservation For most of us wildlife is represented by large mammals like elephant, rhino, lion and tiger, may be birds like hornbill, raptors, peafowl and waterfowl and awe inspiring reptiles like marine turtles, crocodiles, python and king cobra. …

Bay in distress

The Goa government’s reluctance to scrap a controversial shipyard project has left the 200-odd families of Chicalim village distraught. In 2005, Bharti Shipyard Limited proposed to construct a Rs 250-crore shipyard on about 0.8 hectare of mudflats in the ecologically fragile Chicalim Bay in Mormugao taluka. The Goa Coastal Zone …

Sharks in soup

George and Aruldas, fishermen from near Kanyakumari, were hauling up a catch on a beach in southern Tamil Nadu. It was a warm evening and they were the only fishers on these secluded sands. The catch was special and I was privileged, as an outsider, to be invited to watch …

Fatal warming

A LAB study shows global warming that increases sea-surface temperatures would make cold-blooded creatures of the sea vulnerable. A slight increase in temperature may be conducive to growth. Above a certain temperature threshold, the metabolic demands of tissues such as supply of oxygen progressively limit the energy available for growth …

Sea’s toxic touch

IT is a neurotoxin that accumulates in marine organisms and can have serious implications on human health. The toxin, monomethylmercury, is of particular concern to people whose traditional diet consists of seafood. But the source of monomethylmercury in oceans has remained uncertain. It was till now suspected that industries were …

The noisier, the healthier

CORAL reefs that offer exotic ocean views can be surprisingly noisy places, with tiny fish and invertebrates like lobsters, sea urchins, squids and corals producing a relentless cacophony of squeaks and grunts. UK scientists recently listened to these noises and found the noisier the reef the better is its health; …

Brown oil and silvery sheen

Erika, who is a photographer, and myself, headed out in a boat from Fourchon, US state Louisi ana’s southernmost port. We had four co-travellers: Jonathan Henderson from non-profit Gulf Restoration Network, his friend Randy, who is a cameraman, and Craig, our fishing captain and guide. It was August 16, the …

An ocean of wealth

FISHERS’ folklores are full of them but the creatures of the deep sea are still a mystery. An inventory of marine species, to be released in London on October 4, would answer the age-old question— what lives in the oceans? The Census of Marine Life, a network of researchers from …

The impact of whaling on the ocean carbon cycle: Why bigger was better

Humans have reduced the abundance of many large marine vertebrates, including whales, large fish, and sharks, to only a small percentage of their pre-exploitation levels. Industrial fishing and whaling also tended to preferentially harvest the largest species and largest individuals within a population. We consider the consequences of removing these …

Nemo finds its predator

HOW do small fish survive predators lurking in the deep ocean? Nature has its way of cautioning them. Species of fish, like mackerel, clownfish and damselfish, have a heightened sense of smell to detect threats and find shelter. Not for long though. Scientists from James Cook University in Australia said …

Impact of ocean warming and ocean acidification on larval development and calcification in the sea urchin Tripneustes gratilla

As the oceans simultaneously warm, acidify and increase in PCO2, prospects for marine biota are of concern. Calcifying species may find it difficult to produce their skeleton because ocean acidification decreases calcium carbonate saturation and accompanying hypercapnia suppresses metabolism. However, this may be buffered by enhanced growth and metabolism due …

Climate change may be sparking new and bigger "dead zones"

“Wasteland” conjures up visions of dusty desolation where life is fleeting and harsh—if it exists at all. Oceans, too, have their inhospitable pockets. Scientists are discovering that climate change—and not just fertilizer from farm use—may be spurring the emergence of barren underwater landscapes in coastal waters. Expanding dead zones not …

How vulnerable is Indian coast to oil spills? Impact of MV Ocean Seraya oil spill

On 30 May 2006, a bulk carrier, MV Ocean Seraya ran aground along the Karwar coast spilling 650 tonnes of oil. Due to the rough SW monsoon, the spill spread to some beaches in south Goa. The aim of this communication is to study the immediate impact of oil spill …

Expanding oxygen-minimum zones in the tropical oceans

Oxygen-poor waters occupy large volumes of the intermediate-depth eastern tropical oceans. Oxygen-poor conditions have far-reaching impacts on ecosystems because important mobile microorganisms avoid or cannot survive in hypoxic zones. Climate models predict declines in oceanic dissolved oxygen produced by global warming. The researchers constructed a 50-year time series of dissolved-oxygen …

Wake up, before it is too late!

Over twenty years ago, Goa enjoyed the peak of its fishing industry. So abundant was the catch, many fishermen made the comment:

Oceans at risk: Many studies, little action

There is no shortage of scientific studies documenting the degradation of the world's oceans, the decline of marine ecosystems and the collapse of important fish species. Several have appeared in the last month. What is in short supply is a sustained effort by world governments and other institutions to do …

Sharks being killed: Cosmetic industry gains (Editorial)

Environmental management does not mean changing your light bulbs to use less energy. It means looking at everything you use to see what is beingdestroyed. Have you ever looked at the ingredients in your make up or lotions? Does your moisturizer or lipstick carry the word squalene in the ingredient …

Climate change to adversely impact global fish production

Climate change could adversely impact the fish production globally, a latest report by United Nation Environment Programme (UNEP) said. The report tilted

Marine animals smuggled from Lanka seized

Veterinary inspectors at Ben-Gurion Airport on Monday seized a shipment of marine animals banned for import into Israel. The contraband - eight starfish, 28 sea urchins and 15 small crustaceans - was smuggled from Sri Lanka via Jordan inside a shipment of aquarium fish and shrimp. Haartesz, Israel
