	Keywords	Corticosterone stress response Defensive behavior Offspring stress sensitivity Parental presence
	Abstract	In altricial species, parents brood their chicks constantly before leaving them unattended sometimes for extended periods when they become thermally independent. During this second phase, there is sometimes important inter-individual differences in parental attendance and the fitness costs and benefits of parental strategies have previously been extensively investigated. However, the impact of parental presence on offspring behaviors and stress physiology has been overlooked. Here, we examined the influence of parental presence on offspring hormonal and behavioral stress sensitivities in snow petrel chicks. We demonstrated for the first time in a wild bird species that attended chicks had lower stress-induced corticosterone levels and a lower probability to show defensive behavior compared to the alone chicks. This reduced stress sensitivity is certainly explained by the well-known link between corticosterone and nutritional status, and by the recent delivery of meals to the attended chicks and the improvement of their nutritional status. It may also be explained by the parental protection against predators or inclement weather, or/and by the psychosocial comfort of parental presence for the offspring. Overall, these results suggest that the presence of a parent in the nest reduces offspring stress sensitivity in wild birds. Further studies would now be required to disentangle the impact of nutritional status and parental presence on stress sensitivity and to better understand the potential impact of parental presence and circulating corticosterone levels on growth and cognitive development in wild birds.

	Title	Experimental stress during molt suggests the evolution of condition-dependent and condition-independent ornaments in the king penguin			Type	Journal
	Year	2018	Publication	Ecology and Evolution	Abbreviated Journal
	Volume	8	Issue	2	Pages	1084-1095
	Keywords	Corticosterone honest signal Immunity sexual selection social selection
	Abstract	Sexual selection and social selection are two important theories proposed for explaining the evolution of colorful ornamental traits in animals. Understanding signal honesty requires studying how environmental and physiological factors during development influence the showy nature of sexual and social ornaments. We experimentally manipulated physiological stress and immunity status during the molt in adult king penguins (Aptenodytes patagonicus), and studied the consequences of our treatments on colourful ornaments (yellow-orange and UV beak spots and yellow-orange auricular feather patches) known to be used in sexual and social contexts in this species. Whereas some ornamental features showed strong condition-dependence (yellow auricular feather chroma, yellow and UV chroma of the beak), others were condition-independent and remained highly correlated before and after the molt (auricular patch size and beak UV hue). Our study provides a rare examination of the links between ornament determinism and selection processes in the wild. We highlight the coexistence of ornaments costly to produce that may be honest signals used in mate choice, and ornaments for which honesty may be enforced by social mediation or rely on genetic constraints.

	Title	Do glucocorticoids mediate the link between environmental conditions and telomere dynamics in wild vertebrates? A review			Type	Journal
	Year	2018	Publication	General and Comparative Endocrinology	Abbreviated Journal
	Volume	256	Issue		Pages	99-111
	Keywords	Corticosterone Cortisol HPA axis Oxidative stress Stress Telomerase Telomere
	Abstract	Following the discoveries of telomeres and of their implications in terms of health and ageing, there has been a growing interest into the study of telomere dynamics in wild vertebrates. Telomeres are repeated sequences of non-coding DNA located at the terminal ends of chromosomes and they play a major role in maintaining chromosome stability. Importantly, telomeres shorten over time and shorter telomeres seem to be related with lower survival in vertebrates. Because of this potential link with longevity, it is crucial to understand not only the ecological determinants of telomere dynamics but also the regulatory endocrine mechanisms that may mediate the effect of the environment on telomeres. In this paper, we review the relationships that link environmental conditions, glucocorticoids (GC, the main hormonal mediator of allostasis) and telomere length in vertebrates. First, we review current knowledge about the determinants of inter-individual variations in telomere length. We emphasize the potential strong impact of environmental stressors and predictable life-history events on telomere dynamics. Despite recent progress, we still lack crucial basic data to fully understand the costs of several life-history stages and biotic and abiotic factors on telomere length. Second, we review the link that exists between GCs, oxidative stress and telomere dynamics in vertebrates. Although circulating GC levels may be closely and functionally linked with telomere dynamics, data are still scarce and somewhat contradictory. Further laboratory and field studies are therefore needed not only to better assess the proximate link between GC levels and telomere dynamics, but also to ultimately understand to what extent GCs and telomere length could be informative to measure the fitness costs of specific life-history stages and environmental conditions. Finally, we highlight the importance of exploring the functional links that may exist between coping styles, the GC stress response, and telomere dynamics in a life-history framework. To conclude, we raise new hypotheses regarding the potential of the GC stress response to drive the trade-off between immediate survival and telomere protection.

	Title	Dynamically triggered slip on a splay fault in the Mw 7.8, 2016 Kaikoura (New Zealand) earthquake			Type	Journal
	Year	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	Solar Energetic Particle Events in the 23rd Solar Cycle: Interplanetary Magnetic Field Configuration and Statistical Relationship with Flares and CMEs			Type	Journal Article
	Year	2013	Publication	SOLAR PHYSICS	Abbreviated Journal
	Volume	282	Issue	2	Pages	579-613-
	Keywords	Coronal mass ejections, interplanetary, Energetic particles, Magnetic fields, interplanetary,
	Abstract	We study the influence of the large-scale interplanetary magnetic field configuration on the solar energetic particles (SEPs) as detected at different satellites near Earth and on the correlation of their peak intensities with the pa\-rent solar activity. We selected SEP events associated with X and M-class flares at western longitudes, in order to ensure good magnetic connection to Earth. These events were classified into two categories according to the global interplanetary magnetic field (IMF) configuration present during the SEP pro\-pagation to 1~AU: standard solar wind or interplanetary coronal mass ejections (ICMEs). Our analy\-sis shows that around 20\% of all particle events are detected when the spacecraft is immersed in an ICME. {\bf The correlation of the peak particle intensity with the projected speed of the SEP-associated coronal mass ejection is similar in the two IMF categories of proton and electron events, $\sim 0.6$.} The SEP events show stronger correlation of the peak proton intensity with the soft X-ray flux of the associated solar flare, $r=0.67^{\pm 0.13}$, compared to the SEP events propagating in the standard solar wind, $r=0.36^{\pm 0.13}$. {\bf The difference is more pronounced for near-relativistic electrons. The main reason for the different correlation behaviour seems to be the larger spread of the flare longitude in the SEP sample detected in the solar wind as compared to SEP events within ICMEs. We discuss to which extent observational bias, different physical processes (particle injection, transport, etc.) and the IMF configuration can influence the relationship between SEPs and coronal activity

	Title	Seismic visibility of melt at the core-mantle boundary from PKKP diffracted waves			Type	Journal
	Year	2022	Publication	Earth and Planetary Science Letters	Abbreviated Journal
	Volume	595	Issue		Pages	117768
	Keywords	core-mantle boundary lower mantle melt PKKP diffracted seismic visibility
	Abstract	The core-mantle boundary (CMB) is a complex and poorly understood region of the Earth. The existence of melt or partial melt at the CMB is strongly debated with evidence coming from a range of sources. While partial melt has been inferred in specific locations using seismology, often as an explanation for ultra-low velocity zones (ULVZs), no global layer of melt has been observed despite evidence that such melt should accumulate at the CMB. Using high frequency synthetic seismograms we have systematically examined the effect of a one-dimensional melt layer at the CMB on the global seismic wavefield. We find that PKKP diffracted waves are an extremely sensitive, robust and previously underutilised seismic phase for studying the CMB and, in synthetic testing, could resolve very thin melt layers. We have constructed a global data set of PKKP diffracted observations to attempt to observe or exclude melt at the CMB. We find that within the bounds of our data, we are unable to robustly exclude or observe a melt layer at the CMB on the order of single kilometres thick. The presence of a thin layer of unobservable melt at the CMB would have profound impacts for the internal dynamics of the Earth.
