Sex-specific effects of fisheries and climate on the demography of sexually dimorphic seabirds

first_img1.Many animal taxa exhibit sex‐specific variation in ecological traits, such as foraging and distribution. These differences could result in sex‐specific responses to change, but such demographic effects are poorly understood.2.Here, we test for sex‐specific differences in the demography of northern (NGP, Macronectes halli) and southern (SGP, M. giganteus) giant petrels – strongly sexually size‐dimorphic birds that breed sympatrically at South Georgia, South Atlantic Ocean. Both species feed at sea or on carrion on land, but larger males (30% heavier) are more reliant on terrestrial foraging than the more pelagic females. Using multi‐event mark‐recapture models, we examine the impacts of long‐term changes in environmental conditions and commercial fishing on annual adult survival and use two‐sex matrix population models to forecast future trends.3.As expected, survival of male NGP was positively affected by carrion availability, but negatively affected by zonal winds. Female survival was positively affected by meridional winds and El Niño–Southern Oscillation (ENSO), and negatively affected by sea ice concentration and pelagic longline effort. Survival of SGPs did not differ between sexes; however, survival of males only was positively correlated with the Southern Annular Mode (SAM).4.Two‐sex population projections indicate that future environmental conditions are likely to benefit giant petrels. However, any potential increase in pelagic longline fisheries could reduce female survival and population growth.5.Our study reveals that sex‐specific ecological differences can lead to divergent responses to environmental drivers (i.e. climate and fisheries). Moreover, because such effects may not be apparent when all individuals are considered together, ignoring sex differences could underestimate the relative influence of a changing environment on demography.last_img read more

The impact of temperature and crystal orientation fabric on the dynamics of mountain glaciers and ice streams

first_imgStreaming ice accounts for a major fraction of global ice flux, yet we cannot yet fully explain the dominant controls on its kinematics. In this contribution, we use an anisotropic full-Stokes thermomechanical flow solver to characterize how mechanical anisotropy and temperature distribution affect ice flux. For the ice stream and glacier geometries we explored, we found that the ice flux increases 1–3% per °C temperature increase in the margin. Glaciers and ice streams with crystallographic fabric oriented approximately normal to the shear plane increase by comparable amounts: an otherwise isotropic ice stream containing a concentrated transverse single maximum fabric in the margin flows 15% faster than the reference case. Fabric and temperature variations independently impact ice flux, with slightly nonlinear interactions. We find that realistic variations in temperature and crystallographic fabric both affect ice flux to similar degrees, with the exact effect a function of the local fabric and temperature distributions. Given this sensitivity, direct field-based measurements and models incorporating additional factors, such as water content and temporal evolution, are essential for explaining and predicting streaming ice dynamics.last_img read more

Game 3, 8:30 p.m. MDT, ESPN.NEED TO KNOW: Adversity, meet the Rockets. A team that had winning streaks of 11, 14 and 17 games in the regular season has now ceded home-court advantage to the Jazz. It’s not panic time for the NBA’sNo. 1 overall seed yet – it’s only 1-1 – but Houston must expect Mitchell to shoot better at home in Game 3 than he did on the Rockets’ home floor in Game 2.KEEP AN EYE ON: Jazz F Joe Ingles. He has been superb in these playoffs, with three 20-point games already (as compared to having only two in the final two months of the regular season). The Aussieis playing with enormous confidence right now.INJURY UPDATE: Jazz PG Ricky Rubio (hamstring) remains out.PRESSURE IS ON: Utah. The Jazz know all they’ve done is win one game. Giving the series lead back to Houston in Game 3 would make the challenge of knocking off the Rockets incredibly daunting.

Mitchell and Conley pairing could give Jazz offense a lift

first_img Tags: Donovan Mitchell/Mike Conley/NBA/Utah Jazz/Utah Jazz Media Day Associated Press FacebookTwitterLinkedInEmailSALT LAKE CITY (AP) Utah changed the entire dynamic of its backcourt after acquiring veteran point guard Mike Conley from the Memphis Grizzlies in July. Will it be enough to turn the Jazz into an NBA championship contender?That’s what Utah is banking on heading into the 2019-20 season. Conley joins rising star Donovan Mitchell to form what could be one of the league’s more potent backcourt duos in the season ahead.Mitchell averaged 23.8 points and 4.2 assists in his second season, but struggled at times with his scoring efficiency. Conley promises to relieve some of the playmaking burden that Mitchell felt at times as an NBA sophomore.”Mike Conley is an elite point guard,” Quin Snyder said at the team’s media day on Monday. ”When I say elite that manifests in a lot of different ways. Certainly on the court, some of the things he does and the feel he has for the game and for players around him is really unique. He impacts the game.”Conley is one of the league’s most efficient point guards in the pick-and-roll and a reliable shooter. He scored a career-best 21.1 points per game in his final season in Memphis while also averaging 6.4 assists per game.Mitchell anticipates seeing Utah’s offense open up thanks to Conley’s patience and court vision.”He’s a guy who goes at his own pace and that’s one of the things I’m really starting to learn,” Mitchell said. ”It’s not really always about getting in there and scoring. He’s creating and finding guys who are open.”For his part, Conley is savoring the potential of joining Mitchell in the backcourt and playing with a talent-laden roster that also includes two time NBA Defensive Player of the Year Rudy Gobert.”We have a team, with our depth and guys who play both sides of the ball, that allows us to get into a lot of different schemes that the other team might not be able to do, which is exciting,” Conley said. ”It’s exciting when you have that versatility.”Other things to know about the Utah Jazz heading into the 2019-20 season:INTERNATIONAL FLAVOR:Six of the 20 players on Utah’s training camp roster come from outside the United States. Two of those players, Gobert (France) and Joe Ingles (Australia), played key roles in driving their national teams to success in the 2019 FIBA World Cup.Gobert credits the NBA with making big strides in growing the game globally with the influx of international players playing for the Jazz and other teams in the league. The league plans to broadcast multiple games during prime time in Europe this season, including three Utah games.”Twenty years ago, it was harder for those kids to think they were going to be NBA players,” Gobert said. ”Now, anywhere in the world, you can have that goal and I think it’s great for the game.”VETERAN PRESENCEThe Jazz signed multiple veteran free agents to help boost their offense and defense during the offseason. Bojan Bogdanovic was the highest profile free agent to join Utah, signing a four-year, $73.1 million deal in July. Bogdanovic averaged a career-best 18.0 points for Indiana last season and shot 42.5% from 3-point range.Utah also added Jeff Green, Ed Davis, and Emmanuel Mudiay on shorter deals in July. Davis gives the Jazz a defensive specialist who can spell Gobert in the middle when needed. Green adds additional scoring punch on the wing.”We have it all on paper,” Green said. ”We have to translate it on court when the season starts.”HEALTHY AGAINMitchell was limited in his offseason training last summer when he suffered a foot injury at the end of his rookie season. The third-year guard had no such issues this summer, playing for Team USA in the 2019 FIBA World Cup and getting plenty of time in the gym to workout with teammates like Conley and Royce O’ Neale.”I could go to the gym whenever I wanted to shoot,” Mitchell said. ”That’s one of the things you really miss when you get hurt.”PROVING GROUNDGreen signed a one-year deal with the Jazz in July – his fourth consecutive year on a one-year contract. He is with his sixth team in five seasons after posting 12.3 points per game on 47.5% shooting for Washington last season. Utah views him as a potential starter or sixth man.For Green, joining Utah is equally about playing for a championship contender and proving his value to the rest of the league.”I’m never satisfied,” Green said. ”I think when you are, that’s when you have an early exit.” Written by October 1, 2019 /Sports News – Local Mitchell and Conley pairing could give Jazz offense a liftlast_img read more
