  Title Dynamically triggered slip on a splay fault in the Mw 7.8, 2016 Kaikoura (New Zealand) earthquake Type Journal
  Year (down) 2017 Publication Geophysical Research Letters Abbreviated Journal  
  Volume 44 Issue 8 Pages 3517-3525  
  Keywords correlation earthquake New Zealand rupture seismology slip inversion  
  Abstract Abstract We investigate the Mw 7.8, 2016 Kaikoura (New Zealand) earthquake by using optical satellite imagery and seismology to reveal the main features of the rupture process. Correlation of Landsat8 images reveals a 30?40?km surface rupture on the Kekerengu Fault and Jordan Thrust, with up to 12?m of right?lateral slip. A previously unrecognized conjugate strike?slip fault, the Papatea Fault, also slipped coseismically (3?4?m). The global centroid moment tensor (gCMT) centroid indicates both thrust and right?lateral slip and is located ~100?km NE of the main shock epicenter. The significant non?double?couple component of the gCMT (25%) suggests that the main shock is not well represented by a single planar fault. Back projection of teleseismic P waves reveals two main bursts of seismic radiation: (1) at 10?20?s, near the main shock epicenter, and (2) at ~70?s, close to the observed surface ruptures. We determine a finite source kinematic model of the rupture from the inversion of seismic waveforms. We use two faults in our model, defined to match the observed slip on the Kekerengu Fault, and a deeper offshore fault with a lower dip angle to satisfy the long period seismological observations. We compute the equivalent moment tensor from our finite source model and find it to be remarkably consistent with the gCMT solution. Although little is known about the geometry of these faults at depth, if the Kekerengu Fault splays from the deeper thrust, then it provides a rare example where the contribution of slip on a splay fault can be clearly isolated in the seismological waveforms.

  Title Modeling of ground albedo neutrons to investigate seasonal cosmic ray?induced neutron variations measured at high?altitude stations Type Journal
  Year (down) 2017 Publication Journal of Geophysical Research: Space Physics Abbreviated Journal  
  Volume 121 Issue 12 Pages 12,186-12,201  
  Keywords albedo neutron cosmic ray spectrometer  
  Abstract Abstract This paper investigates seasonal cosmic ray?induced neutron variations measured over a long?term period (from 2011 to 2016) in both the high?altitude stations located in medium geomagnetic latitude and Antarctica (Pic?du?Midi and Concordia, respectively). To reinforce analysis, modeling based on ground albedo neutrons simulations of extensive air showers and the solar modulation potential was performed. Because the local environment is well known and stable over time in Antarctica, data were used to validate the modeling approach. A modeled scene representative to the Pic?du?Midi was simulated with GEANT4 for various hydrogen properties (composition, density, and wet level) and snow thickness. The orders of magnitudes of calculated thermal fluence rates are consistent with measurements obtained during summers and winters. These variations are dominant in the thermal domain (i.e., En??20?MeV) is weakly impacted. The role of hydrogen content on ground albedo neutron generation was investigated with GEANT4 simulations. These investigations focused to mountain environment; nevertheless, they demonstrate the complexity of the local influences on neutron fluence rates.

  Title Around the pole: evolution of sub?Antarctic Ranunculus Type Journal

  Keywords dispersal divergence time estimates ecomorphology historical biogeography phylogenetic biogeography Ranunculus sub?Antarctic islands  
  Abstract Abstract Aim Despite an improved understanding of Southern Hemisphere plant biogeography, the origins and evolution of sub?Antarctic floras remain poorly studied. Here, we investigate the historical biogeography of sub?Antarctic representatives of the genus Ranunculus. We aimed to establish when and from where the sub?Antarctic ranunculi originated as well as to examine the extent to which ecomorphological traits explain contemporary biogeographical patterns. Location Southern temperate and sub?Antarctic zones. Methods We first estimated a dated phylogeny for Ranunculus using combined chloroplast and nuclear data for 53 accessions; divergence times were inferred based on three temporal calibrations. We then used non?parametric multidimensional scaling to evaluate the ecomorphological diversity of 67 austral ranunculi representing a combination of sub?Antarctic species and those restricted to lower latitude landmasses. Results Phylogenetic analyses indicated that several Ranunculus lineages have colonized the sub?Antarctic islands. Divergence time estimates suggest recent arrival from source areas in Australia, New Zealand or South America. Species exhibiting two distinct ecomorphological trait combinations occur in both sub?Antarctic and lower latitude habitats; the proportions of each combination differed significantly between these areas. Main conclusions Ranunculus has colonized the sub?Antarctic on several occasions, most often arriving from the lower latitude landmasses prior to the Last Glacial Maximum. Taken together our analyses suggest that chance effects are likely to have influenced species arrival. However, following arrival trait?environment interactions appear to have been important for the subsequent establishment and persistence of ranunculi in sub?Antarctic habitats.

  Title Reproductive effort and oxidative stress: effects of offspring sex and number on the physiological state of a long?lived bird Type Journal
  Year (down) 2017 Publication Functional Ecology Abbreviated Journal  
  Volume 31 Issue 6 Pages 1201-1209  
  Keywords black?legged kittiwake cost of reproduction hypothesis malondialdehydes oxidative cost of reproduction parental care Rissa tridactyla: superoxide dismutase sex allocation  
  Abstract Summary Individuals must trade?off between energetically costly activities to maximize their fitness. However, the underlying physiological mechanism remains elusive. Oxidative stress, the imbalance between reactive oxygen species production and antioxidant and/or repair activities, has been suggested to underlie life?history trade?offs: greater investment in reproduction supposedly generating higher oxidative damage, thus reducing life span. While most studies used natural or experimental variation in offspring number to examine how reproduction affects oxidative stress, none studied the impact of offspring sex, although it could influence physiological costs and fitness, if the sexes differ in terms of energetic cost. Here, we aim at further understanding how reproduction (in terms of offspring sex, experimentally manipulated and number, not manipulated) influences oxidative stress in a wild seabird, where sons are energetically costlier than daughters. We did so by conducting a chick fostering experiment (to disentangle foster and produced sex ratio) and using four oxidative stress markers plus baseline corticosterone. First, the results suggest that individual physiological state before laying modulates upcoming reproductive effort. Individuals with higher pre?laying baseline corticosterone and lower antioxidant activity, estimated by their superoxide dismutase activity, subsequently invested more in reproduction, estimated by the cumulative number of days spent rearing chicks. Hence, it seems that only individuals that could afford to invest heavily in reproduction did so. Then, we examined the effects of reproductive effort on individual physiological state at the end of the breeding season. Higher reproductive effort seemed to imply higher physiological costs. Oxidative stress, estimated by the ratio of oxidized over reduced glutathione, increased with more male?biased foster sex ratio among mothers but not among fathers, whereas baseline corticosterone did so in both sexes. Similarly, lipid oxidative damage to red blood cells increased with increasing cumulative number of days spent rearing chicks. Our study provides the first evidence that brood sex ratio variation can affect oxidative balance, potentially in a sex?specific way, although more studies are needed to understand whether the observed physiological costs could lead to fitness costs. It also highlights the need to consider sex ratio in future studies investigating the role of oxidative stress in life?history trade?offs. A lay summary is available for this article.
