GPS and Time-Depth Recorder tracking of common and Brunnich's guillemots from five colonies around Iceland, June-July 2019-2021

Norman Ratcliffe & Anne-Sophie Bonnet-Lebrun
We tracked 94 common and 50 Brunnich's guillemots from five colonies around Iceland (Latrabjarg, Grimsey, Langanes, Skrudur and Papey) during late incubation and chick rearing from June to July 2019. We also tracked 5 common and 3 Brunnich's guillemots from Langanes during chick-rearing in July 2020 (GPS only). We used Pathtrack nanoFix GPS loggers to record locations every 3min and Cefas G5 TDR loggers to record depth every second. The tags recorded the birds' behaviour...

Diversification patterns in Boeckella

Claudia Maturana
Aim: We investigated evolutionary relationships and biogeographical patterns within the genus Boeckella to evaluate: 1) whether its current widespread distribution in the Southern Hemisphere is due to recent long-distance dispersal or long-term diversification; and 2) the age and origin of sub-Antarctic and Antarctic Boeckella species, with particular focus on the most widely distributed species: B. poppei. Location: South America, sub-Antarctic islands, maritime Antarctica, continental Antarctica and Australasia. Methods: To reconstruct phylogenetic patterns of Boeckella, we...

Evidence for an Allee effect in a declining fur seal population

Rebecca Nagel, Claire Stainfield, Cameron Fox-Clarke, Camille Toscani, Jaume Forcada & Joseph Hoffman
Allee effects play an important role in the dynamics of many populations and can increase the risk of local extinction. However, some authors have questioned the weight of evidence for Allee effects in wild populations. We therefore exploited a natural experiment provided by two adjacent breeding colonies of contrasting density to investigate the potential for Allee effects in an Antarctic fur seal (Arctocephalus gazella) population that is declining in response to climate-change induced reductions in...

Electron Electromagnetic Ion Cyclotron diffusion coefficients calculated from Van Allen Probe observations

Johnathan Ross & Sarah Glauert
Electromagnetic Ion Cyclotron (EMIC) wave are important for the losses of ultra-relativistic electrons from the Earth's radiation belts. In this work, statistical EMIC diffusion coefficients are calculated from Van Allen Probe A observations of EMIC waves from the entire mission. The diffusion coefficient calculations include the observed L* and activity dependent distributions in plasma density and wave spectra so that the wave-particle interactions modelled are representative of those in the radiation belts. These diffusion coefficients...
