The energy expenditure of free-ranging black-browed albatrosses


first_imgAs heart rate (f$_{text{H}}$) can be used to determine the energy expenditure of black-browed albatrosses (Diomedea melanophrys) (Bevan et al. 1994), data loggers – recording f$_{text{H}}$ and abdominal temperature (T$_{text{ab}}$) – were implanted into free-ranging black-browed albatrosses breeding at South Georgia. Five birds also had salt water switches (sws) attached to one leg to record when the birds were on the water, and two others had satellite transmitters attached to their back to determine the birds’ position at sea. The birds were released into their natural environment and recaptured, on average, 23 days later when the data loggers were removed. The f$_{text{H}}$ data were then converted into estimates of energy expenditure (EE) using a previously derived equation. The mean EE during incubation and brooding were 2.22 and 2.42 W kg$^{-1}$, respectively. When the birds were foraging at sea, EE increased to between 4.63 and 5.80 W kg$^{-1}$, depending on the phase of the reproductive cycle. As the birds spent approximately the same length of time at the nest and at sea during incubation and brooding, the overall mean EE during these phases were 3.63 and 3.54 W kg$^{-1}$ respectively. These rates are significantly lower than that during the chick-rearing phase when a high level of foraging EE is maintained almost continuously. By combining information from the sws with the f$_{text{H}}$ data, it was possible to determine the EE of the birds when on the water (5.77 W kg$^{-1}$) and when flying (6.21 W kg$^{-1}$). These values are approximately twice the estimated basal metabolic rate (BMR) for the species. The energy costs of flight are half previous values, estimated using the doubly labelled water technique, because of the previous assumption that birds on the water have an EE equivalent to BMR. When the birds were on the nest, T$_{text{ab}}$ was 39.3 $pm $ 0.4 degrees C and this changed very little with time. However, when they were at sea, T$_{text{ab}}$ showed large variations, depending on the behaviour of the bird. Information from the sws indicated that all large drops (> 0.5 degrees C) in T$_{text{ab}}$ occurred when the birds were on water. The mean minimum value reached was 32.5 $pm $ 2.0 degrees C. It is likely that ingestion of prey or water are the major causes of this decrease. This is the first study to have used f$_{text{H}}$ extensively to determine the EE of a free-ranging marine bird. The advantages of using this technique are that data can be obtained over long durations with high resolution, permitting the EE of different activities to be estimated.last_img read more

USC prepares for Thursday night game


first_imgThursday’s football game against the University of Arizona Wildcats marks the first non-bowl game to be held on a Thursday at the Los Angeles Memorial Coliseum and with it will bring new gameday procedures.The reason behind the schedule change this year is because USC is required to host a Thursday night game twice every three years as a member of the Pac-12 Conference, USC Associate Athletic Director Jose Eskenazi said.“It’s a mandated thing from the conference,” Eskenazi said. “It’s obviously not our preference to host a Thursday night game, but we have to do it, and were excited to do it in the sense that we’ll tackle it head-on and hopefully it’ll be a great game experience for all those that attend.”For the Thursday night game, no on-campus parking for the game or on-campus tailgating will be allowed.Captain David Carlisle said the university made the decision to ban campus activities to ensure that academics on campus will not be interrupted.“This being the first Thursday night game ever for USC, it’s going to be a challenge in that there will be no tailgating allowed on campus,” Carlisle said. “That is a decision that the university has made because it is going to be considered a normal academic day.”Since no on-campus parking will be available to those attending the game, other options will be made available.“Parking will be available down in L.A. Live and several lots will be open that folks can park there, and there will be a shuttle service to and from the Coliseum,” Eskenazi said.Tailgating opportunities have also been added at the Galen Center and the Coliseum.“To make up for the lack of tailgating on campus, the Galen Center will have an open tailgate that you can walk up to and pay to attend, and also the Cardinal and Gold Picnic at the Coliseum has opened up spaces for the general public,” Eskenazi said.Thursday classes will be held on their regular schedules.“Some schools cancel classes if they host a weekday football game,” Eskenazi said. “At USC, it was the administration’s decision not to do that. USC is an academic institution first and foremost, so classes are regularly scheduled and all ongoing regular campus activities will go on.”Both DPS and the Athletic Department have been preparing for months to make sure that the night goes smoothly.“We’ve been planning this for a good eight to nine months,” Eskenazi said. “It all started with getting all groups on campus together to talk about what the plans should be and what the communications would be, and making sure we adhere to the university policy that classes would still be in session and find alternatives for people to be able to attend the game.”Gian Johl, a graduate student studying business administration who plans to attend the game, said that his midterm was rescheduled as a result of the football game.“The class voted to take the midterm early because of logistics,” Johl said.Ronan Young, a freshman majoring in business administration who regularly attends USC football games, said he thinks the Thursday night date will negatively affect student attendance.“I feel like the student attendance won’t quite be the same because a lot of people that would say, go on a Saturday because it’s the only thing to do, now have work to do or schoolwork to do, and now they’re going to choose not to go,” Young said.Sean Lee, an undecided freshman who is choosing not to go to the game, also believes the date will hinder attendance.“I have the student section tickets, but I’m selling mine because I can’t make it,” Lee said. “I have a 9 a.m. class and a lot of stuff going on Friday.”Others students, however, said that the usual schedule will not stop them from going to the game.“I will definitely be attending,” said Paul Samaha, a freshman majoring in public relations. “Most people I know are still going.”The Athletic Department said they are aware of the effect that the new date could have on game attendance.“Everyone is used to it being on a Saturday so it’s a change-up from the traditional college football attending experience,” Eskenazi said. “Obviously work and school schedules will affect your ability to attend.”Nevertheless, the department is excited for this new opportunity.“It’s the first time we’ve had this sort of ‘week night under the lights’ kind of game,” Eskenazi said. “Coach [Orgeron] is pretty excited about it and he really wants the students’ support, sort of this renewed energy of the team with his leadership. I think it could be a pretty fun deal for students.”last_img read more


Digna Strautmane scores career-high 19 points in Syracuse’s 72-62 win over Drexel


first_imgMegan Marecic, who scored a first-half-high 15 points for Drexel, drove to her dominant left side towards Digna Strautmane and attempted a lefty runner. Strautmane extended both her arms, blocking the shot with two hands. The ball trickled away as Strautmane immediately dove on the floor after it. She gathered the ball and drew a foul on the late-to-dive Marecic.Syracuse (10-0) trailed by eight points at halftime but took charge in the second half, in large part because of Strautmane’s play. The freshman’s career-high 19 points, 11 rebounds and four blocks helped SU come back against Drexel (6-4), 72-62, on Saturday night in the Carrier Dome. Strautmane’s rebound and block totals also matched career-highs. Nine of her points, five of her rebounds and the two-handed block came in a momentum-changing third quarter.“We were definitely trying to get the ball to her inside,” SU head coach Quentin Hillsman said. “We knew if we could get the ball inside, we could exploit some of the matchups they had.”The Orange began the second half trailing the Dragons, 41-33. SU had struggled to get the ball into the middle of Drexel’s matchup zone, meaning DU never had to worry about collapsing on an inside presence and could instead lock down the perimeter. Following a Tiana Mangakahia bucket to open the second half, Strautmane began the task of forcing Drexel’s defense to defend the interior. She caught the ball at the free throw line, moved to her right and pulled up for a fadeaway jumper that went through.“She was catching the ball in the high post and making plays,” Hillsman said.AdvertisementThis is placeholder textA few trips down the floor later and Strautmane caught the ball on the left wing, pulled up and drained a 3-pointer. Strautmane continued to showcase her versatility later in the third when she caught the ball on the left block and drop-stepped toward the baseline before extending her left arm out and scooping the ball up and into the basket.Strautmane’s third-quarter scoring concluded with an easy bucket in transition. Gabrielle Cooper stole the ball and fed it to Mangakahia, who spotted Strautmane streaking down the center of the floor. The point guards lob floated up and over Drexel defenders, letting Strautmane simply step up and finish at the basket.“I think the thing helping us the most (in the second half) was that our shots were dropping,” Mangakahia said, “and Digna running the floor so I could look up to her.”By the end of Strautmane’s nine-point third quarter, Syracuse had taken a five-point lead behind a 21-8 third quarter.Strautmane only scored once in the fourth quarter but it was an impressive finish to a career-night. She caught the ball on the right block with her back to the basket with a little more than four minutes left in the game. Using her left foot as a pivot, she stepped with her right toward the baseline and away from the basket. Simultaneously, she leaned her upper body into Drexel’s Niki Metzel, drawing a whistle. As the whistle blew, Strautmane faded away and nailed the shot. She made the free throw to complete the three-point play.“I knew that they’re strong,” Strautmane said. “I just had to put my (power) out there.”It could have been the exclamation point to her night if not for a defensive play a few minutes later.Again, Marecic tried to drive left and again Strautmane waited near the basket. This time, Marecic seemed to sense Strautmane would look to block the shot, so she faded away a bit more and leapt higher. But the Syracuse freshman just swung her right arm back and then straight down through the ball for her fourth and final block of the night.Marecic, who had scored 15 in the first half, contributed just two points to the second-half cause. When SU shut down Marecic’s opportunities to shoot the 3-ball, Strautmane made sure the shutdown continued near the basket.Syracuse needed to shut Marecic down in the second half and needed to consistently score to close the gap with Drexel. Strautmane helped plenty with both causes.“Everybody started to play hard so I just started to push myself, too,” Strautmane said.
