During the late 1960s, larvae of the flightless midge Eretmoptera murphyi Schaeffer were accidentally transferred from the sub-Antarctic island of South Georgia to Signy Island in the maritime Antarctic. Higher insects are rare in the Antarctic and the introduction and establishment of a new species is an unusual event. The fly has overcome the two major barriers to colonization of the Antarctic by new species: the geographical isolation of the region and its severe climate. Larvae of the flightless midge overwinter in the surface layers of soil on Signy Island where the temperature may fall to below -10 degrees C, compared with as little as -1.5 degrees C on South Georgia. This suggests the possession of a level of pre-adaption to colder conditions. Summer-collected larvae have a supercooling point (SCP or whole body freezing point) of approximately -5.0 degrees C but survive experimental exposure to -13 degrees C, giving them a level of freeze tolerance. After acclimation at -4 degrees C for 4 days, the SCP changes little but the temperature at which 50% of the population would die decreases to lower than -19 degrees C. Larvae are also resistant to dehydration. Under experimental conditions of 88% relative humidity at 5 degrees C, larvae lose water linearly (0.42% h-1) over the first 30 h but resist further water loss once their water content decreases to approximately 1.4 g g-1 dry weight. All larvae survive these conditions for the duration of the experiment (55 h). Eretmoptera murphyi is well adapted to survive on Signy Island, and these studies suggest that it has the ability to survive at more extreme locations at higher latitudes if it were to be inadvertently transferred to a suitable habitat.

Ironically, 91 percent of single women say they would marry for love over money.“It is ironic that women place more weight on love than money, yet won’t marry if they or their potential suitor is unemployed,” said Meghan Casserly, Reporter, ForbesWoman. “A job can make or break the longevity of a relationship and the results of the survey demonstrate just what an important role careers play in romance.”YourTango CEO & founder Andrea Miller pointed out that the 9.1% unemployment rate means nearly a tenth of the US population is battling a job loss–and all the love life repercussions that accompany it. One unemployed senior executive and mother of two admitted to YourTango that her job loss was wreaking havoc on her marriage: “I find myself picking fights that I never would. I just feel like a failure, like I’m letting everyone down… I have an amazing husband and a very strong marriage, but this event has effectively changed the DNA of our relationship.”While there are no doubt some benefits to dating the unemployed, there’s no denying the struggles job loss can create in a relationship–foundling and founded alike.by YourTango.com Share Sharing is caring!
AFTER an intense month of footballing action, Fruta Conquerors FC can call themselves Kings of the LIMACOL football tournament.The team overcame their rivals, Santos FC, 2-0 in the final of the tournament on Sunday evening at the Ministry of Education ground, Carifesta Avenue.The match, touted as the grudge match of the best two youth teams in Georgetown, lived up to expectation, with fans petering on the edge of their seats when the ball went into either of the final thirds.Still, both sides were kept in the game during the early stages by their respective shot-stoppers, both men pulling off saves that left the crowd in awe.Not for the want of trying, as each team had more than 10 attempts on the other’s goal, the game had to go the route of extra time as no-one could find the back of the net at the end of 90 minutes.It would take a captain’s effort from Nicholas Mc Arthur to let Fruta surge ahead, his timing in the air proving impeccable as he headed pass the flailing Santos keeper for the first goal of the tournament.The Fruta captain was not finished there; he capitalized on a sensational through ball from Ryan Hackett and slipped it slyly by the keeper for his second of the match and the tournament sealer.For his efforts, the team carted of $400,000 with Santos taking $200,000.In the third place playoff, Riddim Squad edged out Pele with a lone goal in the closing minutes of their game to cop the $100,000 prize. Pele received $50,000.Mc Arthur picked up the most-goals award for his twelve goals, inclusive of two hat-tricks, along with the most valuable player award. Joel Yhap, his team was given the best goalkeeper award.
The City of Miami is included among twenty-one cities and counties, several of which are sanctuary cities, that have pledged to make one million US immigrants American citizens by the end of 2017.These cities are involved in the Naturalize Now initiative. The initiative aims at preventing illegal immigrants from deportation under the Trump administration immigration policy. Although President Trump is not against legal immigration, he has promised to crack down on illegal residency in the U.S. The focus of his administration is deporting undocumented immigrants who are criminals.The other cities/counties Other municipalities in the initiative include: Atlanta, GA; Boston, MA; Cleveland, OH; Charlotte, NC; Chicago, IL; Dallas, TX; Dayton, OH; Jersey City, NJ; Knoxville, TN; Los Angeles, CA; Montgomery County, MD; Paterson, NJ; Pittsburgh, PA; New York City, NY; Salt Lake County, UT; San Francisco, CA; Seattle, CA; South Gate, CA & Tucson, AZ.Mayor Eric Garcetti of Los Angeles and other progressive elected officials have joined in the path to citizenship effort.“We celebrate our independence on July 4, and honor the values of freedom, justice, unity, and equality that make us who we are,” Garcetti said.Stronger US laws The House of Representatives passed two immigration bills June 29, “Kate’s Law” and the No Sanctuary for Criminals Act. The bills exact harsher penalties on those who re-enter the US after being deported. They also put pressure on local governments to cooperate with feds on immigration enforcement.According to the Washington Examiner, the groups and elected officials behind the Naturalize Now initiative are tieing their campaign to patriotic American holidays like the Fourth of July.Miami, Miami-Dade County not official sanctuary cities Neither the City of Miami or Miami-Dade County are formerly designated as sanctuary cities. These cities are so designated because they offer sanctuary to undocumented residents against deportation. The mayors of Miami and Miami-Dad County are dedicating themselves to ensuring documented immigrants have access to becoming citizens by year’s end,Copyright 2017 – Caribbean National Weekly News
