The Police in Berbice have arrested a man in connection to Tuesday’s stabbing of a security guard in New Amsterdam, Berbice, Region Six (East Berbice/Corentyne).The man is said to be the brother-in-law of the now dead security guard and also shared the same home with him.NKomo LaRoseActing on information, investigators went to a house situated at Lot 46 Stanleytown, and nabbed the suspect. The home is owned by a friend of the suspect.According to a source close to the investigation, the suspect has been cooperating with the investigation and has since confessed to the crime.The body of NKomo LaRose called ‘Komo’ 29, of Lot 54 Stanleytown, New Amsterdam was discovered lying in a drain at Lot 41 Stanleytown at about 06:30h on Tuesday.The body had one stab wound to the chest.Meanwhile, the suspect was taken back to the scene on Wednesday afternoon where he provided investigators with details of how the alleged murder was committed. However, the murder weapon was not found.The two brothers-in-law were allegedly involved in a heated argument on Monday afternoon which escalated later that evening.The dead security guard’s wife, Asha Bailey, who is also the sister of the suspect, had reported that she had called the Police after both men had armed themselves with a cutlass and a knife.It was after she had left the home and went to her grandmother’s home about a quarter mile away, that her brother turned up carrying two knives claiming that he was there to kill his sister.However, his grandmother Silvya Moolyneaux instructed him to leave the yard.She had told this publication that at the time the gate was padlocked, and she was not sure whether her grandson jumped over the gate or the fence.Meanwhile, at the scene on Wednesday, the suspect told investigators that it was after he jumped out of his grandmother’s yard that he saw LaRose approaching.He detailed that he ran at LaRose while holding the knife in his hand. LaRose made an attempt to run but this proved futile.The man confessed that he plunged the knife into LaRose’s stomach and fled the scene.Blood stains on the road suggests that the injured man attempted to get to his grandmother-in-law’s yard.Police are continuing their investigations. A post mortem is expected this week. read more
© 2016 Phys.org (Phys.org)—A small team of researchers has found evidence that suggests that as the oceans acidify due to increased carbon dioxide levels, some fish larvae may become lost while looking for a home. In their paper published in the journal Biology Letters, Tullio Rossi, Ivan Nagelkerken, Jennifer Pistevos and Sean Connell, all with The University of Adelaide describe their study of a natural environment that mimics oceans of the future and their experiments with larvae exposed to increased acidification levels This document is subject to copyright.

Credit: Wikimedia / Alessandro Duci Many studies have been done with the goal of better understanding what will happen in the ocean as acidification occurs, but few if any have looked into the possible impact due to changes in sound dispersal. Prior research has shown that fish larval dispersion and then the subsequent finding of a home, is tied very closely to sound—marine life living on a coral reef makes a lot of noise and can serve as a beacon. Fish larvae have evolved an ability to use the noise to find their way home after riding currents for days, weeks or months. But, the researchers wondered, what will happen if the reefs become quieter due to the existence of less marine life in a more acidic ocean?To find out, they ventured first to an undersea carbon dioxide vent off the coast of New Zealand where acidification levels are close to what many believe will become the norm over the next hundred years—they sank microphones and recorded underwater sounds and found that there was much less natural noise than in nearby areas where acidification levels were normal. That suggested that an increase in acidification would indeed mean a quieter underwater world.Next, the researchers went back to their lab and tested mulloway fish larvae responding to changes in acidification—first they exposed a test group to high levels of carbon dioxide for nearly a month, then they put them in a tank to see if they would make their way using acoustic cues, to what should be their natural environment. They did not, they instead avoided them—larvae reared in a normal environment responded positively, as expected. The team also tried putting the damaged larvae in a tank where the conditions were similar to that around the natural carbon dioxide vent and found that they tried to avoid that environment as well. Their simple experiments indicate, the team suggests, that some fish larvae in the future might have to find another way home, or perish.

Sound plays an important role in this process because for larvae of various species, it acts as an orientational cue towards suitable settlement habitat. Because marine sounds are largely of biological origin, they not only carry information about the location of potential habitat, but also information about the quality of habitat. While ocean acidification is known to affect a wide range of marine organisms and processes, its effect on marine soundscapes and its reception by navigating oceanic larvae remains unknown. Here, we show that ocean acidification causes a switch in role of present-day soundscapes from attractor to repellent in the auditory preferences in a temperate larval fish. Using natural CO2 vents as analogues of future ocean conditions, we further reveal that ocean acidification can impact marine soundscapes by profoundly diminishing their biological sound production. An altered soundscape poorer in biological cues indirectly penalizes oceanic larvae at settlement stage because both control and CO2-treated fish larvae showed lack of any response to such future soundscapes. These indirect and direct effects of ocean acidification put at risk the complex processes of larval dispersal and settlement. Baby fish will be lost at sea in acidified oceans read more
