Egg Size and Reproductive Output in the Deep-Water Prawn Pandalus borealis Kroyer, 1838

first_imgThe deep-water prawn Pandalus borealis Kroyer, 1838 was sampled at six locations from Krossfjord, Spitsbergen (79⚬N, close to the known northerly limit of distribution) to Kosterfjord, Sweden (58⚬N, close to the southerly limit in the eastern north Atlantic). Both egg volume and organic content increased towards high latitudes, ranging from 0.39 μ l and 0.21 mg at Bergen, to 0.67 μ l and 0.30 mg at Isfjord, Spitsbergen. Egg volume was positively correlated with both fresh mass and organic content. Reproductive investment (estimated as mass-specific egg biomass: reproductive output, RO) also varied from site to site, but was not correlated with either latitude or egg size. In five of the six populations sampled, reproductive investment calculated on a dry mass basis increased with size (and hence age), but this relationship was statistically significant only at two sites. These data indicate that both egg size and reproductive investment vary from location to location within species, and are uncorrelated. Egg size is related to feeding and other conditions awaiting the newly hatched larva, whereas reproductive investment is dictated by feeding conditions for the adult. The different time-scales over which these two parameters vary (from season to season in RO, and over evolutionary time for egg size) mean that any general relationship between reproductive investment and egg size (and by extension, larval development mode) will be very difficult to demonstrate.last_img read more

The 600 yr eruptive history of Villarrica Volcano (Chile) revealed by annually laminated lake sediments

first_imgLake sediments contain valuable information about past volcanic and seismic events that have affected the lake catchment, and they provide unique records of the recurrence interval and magnitude of such events. This study uses a multilake and multiproxy analytical approach to obtain reliable and high-resolution records of past natural catastrophes from similar to 600-yr-old annually laminated (varved) lake sediment sequences extracted from two lakes, Villarrica and Calafquen, in the volcanically and seismically active Chilean Lake District. Using a combination of micro-X-ray fluorescence (mu XRF) scanning, microfacies analysis, grain-size analysis, color analysis, and magnetic-susceptibility measurements, we detect and characterize four different types of event deposits (lacustrine turbidites, tephra-fall layers, runoff cryptotephras, and lahar deposits) and produce a revised eruption record for Villarrica Volcano, which is unprecedented in its continuity and temporal resolution. Glass geochemistry and mineralogy also reveal deposits of eruptions from the more remote Carran-Los Venados volcanic complex, Quetrupillan Volcano, and the Huanquihue Group in the studied lake sediments. Time-series analysis shows 112 eruptions with a volcanic explosivity index (VEI) >= 2 from Villarrica Volcano in the last similar to 600 yr, of which at least 22 also produced lahars. This significantly expands our knowledge of the eruptive frequency of the volcano in this time window, compared to the previously known eruptive history from historical records. The last VEI >= 2 eruption of Villarrica Volcano occurred in 1991. Based on the last similar to 500 yr, for which we have a complete record from both lakes, we estimate the probability of the occurrence of future eruptions from Villarrica Volcano and statistically demonstrate that the probability of a 22 yr repose period (anno 2013) without VEI >= 2 eruptions is <= 1.7%. This new perspective on the recurrence interval of eruptions and historical lahar activity will help improve volcanic hazard assessments for this rapidly expanding tourist region, and it highlights how lake records can be used to significantly improve historical eruption records in areas that were previously uninhabited.last_img read more

Emerging spatial patterns in Antarctic prokaryotes

first_imgRecent advances in knowledge of patterns of biogeography in terrestrial eukaryotic organisms have led to a fundamental paradigm shift in understanding of the controls and history of life on land in Antarctica, and its interactions over the long term with the glaciological and geological processes that have shaped the continent. However, while it has long been recognized that the terrestrial ecosystems of Antarctica are dominated by microbes and their processes, knowledge of microbial diversity and distributions has lagged far behind that of the macroscopic eukaryote organisms. Increasing human contact with and activity in the continent is leading to risks of biological contamination and change in a region whose isolation has protected it for millions of years at least; these risks may be particularly acute for microbial communities which have, as yet, received scant recognition and attention. Even a matter apparently as straightforward as Protected Area designation in Antarctica requires robust biodiversity data which, in most parts of the continent, remain almost completely unavailable. A range of important contributing factors mean that it is now timely to reconsider the state of knowledge of Antarctic terrestrial prokaryotes. Rapid advances in molecular biological approaches are increasingly demonstrating that bacterial diversity in Antarctica may be far greater than previously thought, and that there is overlap in the environmental controls affecting both Antarctic prokaryotic and eukaryotic communities. Bacterial dispersal mechanisms and colonization patterns remain largely unaddressed, although evidence for regional evolutionary differentiation is rapidly accruing and, with this, there is increasing appreciation of patterns in regional bacterial biogeography in this large part of the globe. In this review, we set out to describe the state of knowledge of Antarctic prokaryote diversity patterns, drawing analogy with those of eukaryote groups where appropriate.last_img read more

Photo credit: www.profootballhof.com Sad news this morning for local football fans, as longtime Wakarusa resident and Pro Football Hall of Fame Running Back Gale Sayers had died at the age of 77.Sayers has publicly been battling dementia for several years with the care of his wife. Sayers known as the “Kansas Comet” was drafted by the Chicago bears in 1965 and had his career cut short by knee injuries, but left the game widely considered one of the best to ever play the sport. He was enshrined into the Hall of Fame in 1977.His death was confirmed this morning by Pro Football Hall of Fame CEO David Baker, who released the following statement:“All those who love the game of football mourn the loss of one of the greatest to ever play this Game with the passing of Chicago Bears legend Gale Sayers. He was the very essence of a team player – quiet, unassuming and always ready to compliment a teammate for a key block. Gale was an extraordinary man who overcame a great deal of adversity during his NFL career and life.The “Kansas Comet” burst onto the scene in the National Football League and captured the attention of all of America. Despite playing only 68 NFL games because of an injury-shortened career, Gale was a clear-cut — and first-ballot — Hall of Famer for his accomplishments on the field and for the man of character he was in life.The entire Pro Football Hall of Fame family mourns the passing of Gale. Our thoughts and prayers are with his wife, Ardie, and their entire family. We will forever keep his legacy alive to serve as inspiration for future generations. The Hall of Fame flag will fly at half-staff until he is laid to rest.”Sayers, unbeknownst to some in the area, lived in the small Elkhart County city of Wakarusa with his wife for more than 20 years. His initial connection to the town can be explained here in a Chicago Sun-Time article from 2006.

Russ Liquid Test Make Waves In Their NYC Debut Performance [Review/Gallery]

first_imgLoad remaining images The Russ Liquid Test dazzled New York City’s American Beauty this past Saturday, February 18th. In the wake of their debut album release, 1984, the electro-funk, psychedelically infused live project have set the tone for a modern take on a retro sound. Russell Scott, keyboard and trumpet virtuoso, has refined his trademark electronic foundations alongside guitarist Andrew Block and drummer Deven Trusclair. Scott gracefully lays a unique electronic foundation that is caressed by sonorous brass. The live music project transcends traditional funk with the deep integration of renowned instrumentals and old-school New Orleans soul.The Russ Liquid Test marks their integration of trademark tracks with unique, live renditions. The group opened the evening with all-encompassing bass that swayed gracefully with pungent guitar riffs and penetrating drums. While Block evinced his string prowess, dazzling the crowd with enduring guitar solos, the ambiance shifted. Divine synths bubbled through the atmosphere, and Scott took an electronic-driven take on the instrumental mood.“Yo, we’re all about abrupt beginnings here,” announced Scott as a jam driven rendition of “Honesty” encompassed the room in heavy brass and trippy vocals. The crowd received Scott’s proclamation with harmonious cheers and shared embraces. The track was drawn out in a mellow tone, caressed by Block’s guitar finesse. The track in itself is beautiful; incorporating elements from each genre, while including classically retro vocals with a psychedelic feel. Its live rendition, however, surpasses that of the record itself bolstering instrumental prominence.“Honesty” was mixed into a vibrant version of “Let Me Stand,” a track that exudes the traditional Russ Liquid sound, yet is graced with the soft caress of enchanting vocals. Emily Nichols led the track into a sultry verse, crooning, “Let me stand all night.” The lyrics were penetrating in tone while they bloom in psychedelic build up. The track, flirting with bubbling synths, was drawn out by soulful and cutting guitar riffs. Graced by sonorous brass notes and light keys, leaving the room in musical entrancement.The night continued with ambient synths complemented by roaring drums and impassioned guitar. Scott introduced, “Acid for Wagner,” from his album In Love. The track held faithful to its roots in liquefying synthesis, yet was aided by the warmth of brass and drums. It was drawn out into a jam led by bubbling trumpet notes and keyboard leads, along with the beautiful guitar riffs integral to the nights’ warm vibe.The night concluded with intoxicating, trumpet-fueled jams that flooded American Beauty with a soulful groove. Each artist, in his skill, contributed extraordinarily to the music project that is now becoming a grand success. Each member provides a unique sound that is gloriously harmonic. The energy that radiates from the stage and onto the crowd is truly beautiful as fans leave beaming time and time again.All photos courtesy of Djivan Schapira and B.a.D Photography.

first_imgLoad remaining images Photo: Vic Brazen Photo: Vic Brazencenter_img On Friday, May 18, Marco Benevento headlined the 3S Artspace in Portsmouth, New Hampshire with opening support from Seacoast soul powerhouse Gretchen and the Pickpockets. Marco Benevento and his band, which features Karina Rykman on bass and Andy Borger on drums, opened the show by playing the entire side B of Marco’s latest album, The Story of Fred Short. At the end of “Stay in Line”, they did an extended tease of Led Zeppelin‘s “Living Loving Maid”. After The Story of Fred Short segment, Marco spoke about his history and love for the city of Portsmouth and why he plays there so often. He went on to give shout-outs to his longtime friend Tristan from 3S Artspace and his favorite restaurant Jumpin’ Jay’s Fish Cafe, which is mentioned in his song At the Show. When the band started back up, they played crowd favorites like “Dropkick”, “Limbs of a Pine”, “At The Show”, Harry Nilsson‘s “Jump Into The Fire”, and the Butthole Surfers‘ “Pepper”, as sung by bassist Karina Rykman. At one point, Benevento talked about the piano he tours with that’s an old ’64 key upright that he paid $100 for on Craigslist. He named it “Gibbs” and went on to play an amazing solo on it.Marco Benevento and his band put on an especially energetic performance, with each member shining on their respective instrument throughout the show. Karina made several leaps across the stage, and Marco climbed up and jumped off instruments, even joining the crowd for a dance toward the end.If you haven’t seen Marco Benevento’s live show yet, we recommend you do so immediately.
