A seasonally varying biotope at Signy Island, Antarctic: implications for meiofaunal structure

first_imgUnder the typical high-latitude conditions of temperature, productivity and settlement of chlorophyll and phaeophytin to the sediment, many benthic organisms in the Antarctic show strong seasonal variation. Although meiofauna comprise an important component of the southpolar benthic ecosystem, our knowledge of them is limited. The metazoan meiofauna and the surrounding sediments were studied fortnightly for 18 mo in a shallow bay at Signy Island (Factory Cove, South Orkneys, Antarctica) to test whether and how the temporal variability of the environment influenced meiobenthos dynamics. By examination of the distribution of the abundance and biomass of the total community, the density of higher taxonomic groups, and of individual dominant nematode genera and feeding categories, we assessed changes in faunal structure. Short-term variations were often effective, and several correlations were observed between temperature and food availability (chlorophyll and its derivatives and bulk organic matter, C and N, in both sediment and water column). However, complex temporal patterns characterised the otherwise fairly predictable seasonal variations of the Antarctic ecosystem. The results suggest that variations in meiobenthic population density and structure were primarily regulated by the input and availability of organic matter and less so by water temperature, which was constantly low. The virtual lack of a Œwinter stop¹ also leads to the conclusion that food was not limiting in the Antarctic coastal sediment.last_img read more

Les Miz Flag-Waver Kyle Scatliffe on Why He’d Make a Terrible Ninja

first_img Age: 27Hometown: Westwood, NJCurrent Role: Waving the flag as Enjolras, student revolutionary, in the Broadway revival of Les Miserables.Stage Cred: Coalhouse Walker in Ragtime in Austin, Jud Fry in Oklahoma! in Seattle and Haywood Patterson in the London premiere of The Scottsboro Boys, a role that just earned him an Olivier Award nomination.“I grew up around Italians, so I talk with my hands all the time. If I’m talking and I start getting passionate about what I’m saying, my hands just start flying around. Big hand talker.”“People in high school would tell me they can hear me coming down the hallway. I have a big laugh. They’d be like, ‘Is Kyle here?’ and you’d hear ‘HAHAHA’ and they’d be like, ‘Kyle’s here.’ It’s like a warning signal. I’d be a terrible ninja.”“I’m 6’5″. When I was a kid, I was 5’7” and I played basketball. But I stopped ’cause it’s not the best height for basketball. Then, out of nowhere, I grew over the summer to six feet and then 6’1” by 11th grade. Everyone was like, ‘Hey, you should come back and play basketball!’ And I was like, ‘I think I like theater more so I’ll see you guys later!”“I was leaving on a Disney cruise when I got cast in The Scottsboro Boys. I would play villains in their Villains Tonight! show. I’d do Hades from Hercules, Jafar from Aladdin… But the best to play was Scar, because The Lion King is my favorite.”“A black kid in Hawaii messaged me after I got the part of Enjolras. He played the role there and was really happy to see that someone could play the part on this scale. It was surreal for me and I thought, ‘This is what Barack Obama must have felt like,’ because when he was voted President, all black people said, ‘Wow, a black person can be President!’”“I stopped moving when I first saw the Enjolras vest and just went ‘Ooh!’ I ran into the boys dressing room and was like, ‘The vest! The vest!’ I was very excited to put it on!” Related Shows Kyle Scatliffe Kyle Scatliffe photographed at the Paramount Hotel for Broadway.com by Caitlin McNaney Star Filescenter_img View Comments Show Closed This production ended its run on Sept. 4, 2016 Les Miserableslast_img read more
