Temperate rainforests near the South Pole during peak Cretaceous warmth

Posted On May 9 2021 by

first_imgThe mid-Cretaceous period was one of the warmest intervals of the past 140 million years1,2,3,4,5, driven by atmospheric carbon dioxide levels of around 1,000 parts per million by volume6. In the near absence of proximal geological records from south of the Antarctic Circle, it is disputed whether polar ice could exist under such environmental conditions. Here we use a sedimentary sequence recovered from the West Antarctic shelf—the southernmost Cretaceous record reported so far—and show that a temperate lowland rainforest environment existed at a palaeolatitude of about 82° S during the Turonian–Santonian age (92 to 83 million years ago). This record contains an intact 3-metre-long network of in situ fossil roots embedded in a mudstone matrix containing diverse pollen and spores. A climate model simulation shows that the reconstructed temperate climate at this high latitude requires a combination of both atmospheric carbon dioxide concentrations of 1,120–1,680 parts per million by volume and a vegetated land surface without major Antarctic glaciation, highlighting the important cooling effect exerted by ice albedo under high levels of atmospheric carbon dioxide.last_img read more

The Main Squeeze Perform “Circle Of Life” In Honor Of Harambe The Gorilla [Watch]

Posted On Mar 2 2021 by

first_imgLast night, The Main Squeeze performed at the Madison Theatre in Covington, KY. Video evidence suggests that they absolutely destroyed the place with their rocking grooves and belting vocals. Being so close to Cincinnati, the Chicago-bred, LA-based quintet decided to pay their respects to Harambe, a 17-year-old Western lowland gorilla that was shot-dead earlier this year at the Cincinnati Zoo.The incident occurred after a three-year-old boy fell into the Zoo’s gorilla enclosure. Taking the child into his own hands, Harambe was shot after showing signs of agitation and disorientation. The event drew nationally controversial reactions regarding the zoo’s handling of the situation. Experts of primatology later concluded that the zoo had no choice under the circumstances, and that the event highlighted the danger of animals in close proximity to humans – but even more, the need for better standards and overall understanding of care and consideration of life.In honor of Harambe’s life, The Main Squeeze performed “The Circle of Life”, delivering an emotionally-charged, yet celebratory tribute to the late gorilla. The band had this to say about the incident: “We wanted to pay our respects to the memory of a majestic creature as well as all of the animals of the animal kingdom. We wished to shed light on the fact that this earth does not revolve around us, and it serves as a reminder to respect the other beings of this great planet and to understand we are just cogs in a much greater circle of life. RIP Harambe.”Watch a clip of the performance below:On a lighter note, the band also shared this recap video from last night’s performance:If you haven’t already, catch The Main Squeeze at a live show near you.

Saint Mary’s announces reentry testing procedures for spring semester

Posted On Jan 26 2021 by

first_imgCollege vice president for enrollment management Mona Bowe and vice president for college relations Shari Rodriguez gave an overview of their plans for spring semester reentry testing in a email to students Friday.According to the message, all students taking classes on campus will be required to submit a negative COVID-19 test result before they move into their residence hall or go to their first class.The College has partnered with Global 7 Diagnostics to provide qualifying students with at-home PCR saliva test kits. Students are exempt from the testing requirement if they test positive for COVID-19 12 weeks or less before the beginning of the semester or plan to complete their semester entirely online, the email said.Bowe and Rodriguez asked all students to complete a survey to determine their eligibility for the PCR test, so they can register for the kit promptly.“If it is determined that you need an at-home test, we ask that you register for your Global 7 test kit as soon as possible,” the email said. “Once your kit is received, you must wait to collect and send in your sample closer to your move-in date.”The test, as well as shipping to and from the student, will cost $107, according to the form students are prompted to fill out. If a student’s insurance does not cover the $75 cost of the test, the College will add the charge to a student’s account. Students will need a credit card when registering for the test to cover the $32 shipping costs.If a student is not able to pay for the test, they can apply for emergency funds through the College.“In early January, watch for an email with details on the move-in process, as well as what to expect for the spring semester,” the email said. “Know that we’re thinking of you and look forward to welcoming you back, particularly those joining us for the first time.”Tags: COVID testing, COVID-19, Mona Bowe, Saint Mary’s College, Shari Rodriguez, Spring 2021last_img read more


Deer Rut

Posted On Jan 17 2021 by

first_imgOnce again, it is that time of year when bucks start chasing does, and deer hunters hit the woods. You guessed it: It is time for the rut, or breeding, season. But the question to be answered is, “How do biologists predict when the rut is going to be?”Rut season is when bucks furiously seek to breed. During this time, buck feeding activity severely decreases, and bucks’ primary goal is to breed as many does as possible. Throughout this period, bucks become aggressively territorial. With whitetail deer, this territorial behavior is not so much about defending a particular piece of land, but rather, excluding other bucks from breeding a receptive female.Understanding the timing and triggers of the rut requires a bit of familiarity with the whitetail life history. The events that precede the rut, like foraging, antler growth, stripping velvet, sparring and fighting, all have a particular purpose. However, while all of these activities are essential to a buck’s successes or failures during the rut, the actual initiating factor that brings about the onset of the rut is much less obvious.Similar to antler growth, the rut is triggered by photoperiod. A decrease in the number of daylight hours causes an increase in melatonin production in the pineal gland within the brain, causing an increase in testosterone production. In does, the increased melatonin levels induce the onset of an estrous cycle.The oscillations in hormone levels generate a physiological response and a change in behavior. Bucks begin to make rubs and scrapes, building muscle in their necks and causing a swollen look. These rubs and scrapes are also the bucks’ calling card for does, as they lay a scent down from a scent gland located on the forehead and in the tarsal region of their hocks. Doe often locate scrapes and urinate in them, signaling that they are receptive to the buck. Bucks are often observed sparring and fighting with other bucks in shows of dominance between bucks in the same area.So now that we have a basic understanding of what the rut is and what causes it, it is time to answer the question from the beginning of the article: How do biologists predict when the rut is going to be? The answer is not as complicated as one may think. Simply put, predicting the rut is primarily done through fetal aging, a technique that has been used by cattle producers and obstetricians for years. It can be done by anyone with a fetal aging scale.To use the fetal aging method, a fetus is extracted from a harvested doe. Once removed, the fetus is laid on a flat surface next to the fetal scale. A measurement is taken from head to rump and recorded. Using this measurement, a date of conception can be determined. Fetal scales operate off of the Julian calendar. To determine when the fetus was conceived, convert the date the doe was harvested to the Julian date. For example, a deer harvested on Dec. 16 would have been harvested on day 350 of the Julian calendar. If the fetus was determined to be 52 days old, then the date of conception would be on day 298, or Oct. 25. Going one step further, had the doe lived, the delivery date would have been on day 496, or May 11.Once biologists determine the number of days from the conception of the fetus, they can take an average among several fetuses and generate an estimate of when the rut was that year. Using the past year’s collection data, a correlation can be established, and the rut window can be projected. It is important to realize that these are merely projections.For information on deer research at the University of Georgia, go to www.ugadeerresearch.org/.last_img read more


Political signs cannot be along public roadways

Posted On Jan 1 2021 by

first_imgThe Vermont Agency of Transportation today issued a reminder for political candidates and their supporters of the need to comply with Vermont’s sign control law when posting campaign signs along public roadways.The Vermont sign law prohibits off-premises signs as well as all types of signs within the limits of public highway rights-of-way, with the obvious exception of traffic-control signs.Political candidates and their supporters often place campaign signs on lawns near a roadway believing they are on private property when many times they are in the highway right-of-way. Most right-of-ways in Vermont are at least 49.5 feet wide, extending 24.75 feet on either side of the centerline and often are wider.“In many instances, placing a campaign sign too close to the road means it is located within the roadway right-of-way,” said VTrans Secretary David Dill. “Clusters of political signs, particularly at intersections, can become a safety hazard as they interfere with sight distances.”Aside from sight distance, another area of concern is the placement of campaign signs in the median or on the edge of limited access highways, entrance and exit ramps to Interstate highways, and other four-lane roads.Each campaign season, state road crews remove signs violating the law from roadway right-of-ways, and will do so again this year.“As in past years, signs that are removed will be kept for 90 days at the local District Maintenance Garage operated by VTrans,” Dill said. “Candidates and their supporters are welcome to visit the garage and retrieve their signs during that time.”Candidates and their supporters are also reminded that there may be local sign ordinances that are stricter than state law and need to be observed. Information regarding local sign ordinances generally can be obtained from the local zoning administrator or municipal clerk.In addition to prohibiting signs in the highway right-of-way, state statutes also prohibit posting any kind of sign or notice on utility poles, regardless of whether the pole is within the right-of-way or on private property.For more comprehensive information on political signs, visit the Secretary of State website at http://vermont-elections.org/elections1/political_signs.html(link is external)Source: VTrans. 6.17.2010last_img read more
