This file contains one line per individual; one column per encounter occasion (from column 1 to 20 were code “0” indicate that the individual was not observed in a particular year; code “1” is used for individuals detected (marked at capture or resighted) with both coloured and steel metal butt-end rings; code “2” is used for individuals detected (marked at capture or resighted) with coloured and steel metal lock-on rings; code “3” is used for individuals resighted only retaining their coloured rings, code “4” is used for individuals resighted only retaining steel metal butt-end rings; and code “5” is used for individuals recovered freshly dead. There are six further columns (21 to 26) indicating the group (starting age at marking form 1-year-old to ≥6 year-old) for each individual., No

Solar radiation is an important driver of animal coloration, not only because of the effects of coloration on body temperature but also because coloration may protect from the deleterious effects of UV radiation. Indeed, dark coloration may protect from UV, but may increase the risk of overheating. In addition, the effect of coloration on thermoregulation should change with egg size, as smaller eggs have higher surface-volume ratios and greater convective coefficients than larger eggs, so that small eggs can dissipate heat quickly. We tested whether the reflectance of eggshells, egg spottiness and egg size of the ground-nesting Kentish plover Charadrius alexandrinus are affected by maximum ambient temperature and solar radiation at breeding sites. We measured reflectance, both in the UV and human visible spectrum, spottiness and egg size in photographs from a museum collection of plover eggshells. Eggshells of lower reflectance (darker) were found at higher latitudes. However, in southern localities where solar radiation is very high, eggshells are also of dark coloration. Eggshell coloration had no significant relationship with ambient temperature. Spotiness was site-specific. Small eggs tended to be light-coloured. Thermal constraints may drive the observed spatial variation in eggshell coloration, which may be lighter in lower latitudes to diminish the risk of overheating as a result of higher levels of solar radiation. However, in southern localities with very high levels of UV radiation, eggshells are of dark coloration likely to protect embryos from more intense UV radiation. Egg size exhibited variation in relation to coloration, likely through the effect of surface area-to-volume ratios on overheating and cooling rates of eggs. Therefore, differential effects of solar radiation on functions of coloration and size of eggshells may shape latitudinal variations in egg appearance in the Kentish plover., Peer reviewed

Horizontal velocities were screened for errors greater than 20cm/s following Gilcoto et al., 2009. Afterwards, each of the 55 current-velocity vertical levels (75 cm bin size) were averaged every 5 minutes. Finally, the MATLAB tidal analysis package t-tide (Pawlowicz et al., 2002) was applied, level by level, to the vectorial combined horizontal velocity components. A database of ellipse parameters for the 55 levels and 53 tidal constituents (selected with a Rayleigh criteria of 1) was obtained. The length of the time series allowed us for the first time to separate S1 and K1, Funding for this study was provided by the Spanish Ministry of Economy and Competitiveness under the STRAMIX (CTM2012-35155) research project., No

Disentangling the influence of demographic parameters and the role of density dependence on species’ population dynamics may be challenging, especially when there are fractions of the population that are unobservable (e.g. dispersers, non-breeders). Additionally, due to the difficulty of gathering data at large spatial scales, most studies ignore the global dynamic of a species, which would integrate heterogeneity in local dynamics and remove the noise of dispersal. We developed a global scale, integrated population model (IPM), to disentangle the main demographic drivers of population dynamics in a long-lived colonial seabird. We used 28 years of Audouin’s gull demographic data encompassing 69 local patches (90% of the world population). Importantly, we took into account the unobservable fraction of non-breeders and also assessed the strength of density dependence for this fraction of the population. As predicted by life histories of long-lived organisms, temporal random variation in survival was highest for immatures (), and lowest for adults (). Large temporal fluctuations in the probability of taking a sabbatical from reproduction would partly explain constancy in adult survival, adults probably refraining from breeding when environmental conditions were harsh. Thus, skipping breeding would be a bet hedging strategy for long-lived organisms having many reproductive chances during their lifespan. Immature survival and fertility were the main drivers of population dynamics during the study period (r2= 0.83 (0.77-0.87) and 0.73 (0.63-0.79) respectively). We found strong evidence of density dependence, not only due to the number of breeders (r2= -0.34 (-0.43 -0.24)) but also to that of sabbaticals (r2= -0.18 (-0.33 -0.01)). Even though population dynamics of long-lived organisms are very sensitive to changes in adult survival, we show here that in the absence of strong environmental perturbations affecting this life history trait, fluctuations in population density in those species may be driven by variations of immature survival and fertility. The species is showing a 5% of annual global decrease during the last ten years, and we propose an updated species conservation status. Integrated models based on long term monitoring at a global scale may enhance our ecological and evolutionary understanding of how demographic drivers influence population dynamics., No

The data acquisition contract was awarded to GECO-PRAKLA and took place in August-September 1993 aboard M/V Geco Sigma. Seismic data was successfully collected along the Cantabrian Margin, Galicia Margin, Iberian Abyssal Plain, the continental platform of Western Iberia, Tagus Abyssal Plain, the Gorringe Bank and Gulf of Cadiz. Data for the 240 km long line IAM-12 was acquired in February 1993 by SEISQUEST vessel of GECO-PRAKLA. The total amount of seismic reflection data collected was 3808.175 km in 19 track lines offshore. Technical specifications of the profiles: Streamer length 4800 m, Number of channels 192, Group interval 25 m, Shotpoint interval 75 m (100 m and 150 m on line IAM-2W), Source 7424 in3 (Record length 25 seconds), Sample rate 4 ms. Contact person: Torne, M., mtorne@ictja.csic.es., The Iberian Atlantic Margins (IAM) project is a multinational research programme, coordinated by the Institute of Earth Sciences of Barcelona, CSIC (Spain). It involves different academic institutions of Britain (University of Oxford and University of Durham), France (IFREMER), Portugal (University of Lisbon and Institute of Meteorology of Lisbon) and Spain (Institute of Earth Sciences of Barcelona, CSIC) and more than 40 associated scientists of European institutions attached to the main contractors. The project, financed by the European Community within its JOULE-Programme (Contract# JOU2-CT92-0177), aims to explore the deep continental and oceanic Atlantic margins of Iberia for a better understanding of the formation and evolution of Atlantic type margins, outstanding structural features and potential location of hydrocarbons and other natural resources. The project was designed to acquire deep seismic multichannel data and onshore recording of wide angle and refraction data along the North Iberian margin; the West Iberia margin, including the Galicia margin, the Iberia and Tagus abyssal plain, and the continental shelf off Portugal; and the Gorringe Bank region and Gulf of Cadiz. The experimental part of the study consisted of the acquisition of over 3700 km of near vertical incidence deep seismic multichannel reflection data. This together with wide angle reflection and refraction data recorded by land stations and OBS (Ocean Bottom Seismometers) has resulted in a full coverage in terms of crustal structure and velocity information of the study region., Peer reviewed

Several models predict changes in the distributions and incidences of diseases associated with climate change. However, studies that investigate how microclimatic changes may affect host–parasite relationships are scarce. Here, we experimentally increased the temperature in blue tit Cyanistes caeruleus nest boxes during their breeding season to determine its effects on the parasitic abundance (i.e. of nest-dwelling ectoparasites, blood-sucking flying insects and hemoparasites) in nests and the host condition of nestlings and adults. The temperature was increased using heat mats placed underneath the nest material, which resulted in an average temperature increase of 3ºC and a reduction in relative humidity of about six units. The abun¬dance of mites Dermanyssus gallinoides and blowfly pupae Protocalliphora azurea was significantly reduced in heated nest boxes. Although not statistically significant, a lower prevalence of flea larvae Ceratophyllus gallinae was also found in heated nests. However, heat treatment did not affect hemoparasite infection of adult blue tits or the body condition of adult and nestling blue tits. In conclusion, heat treatment in blue tit nests reduced nest-dwelling ectoparasites yet without any apparent benefit for the host., Sponsorship: CGL2015-67789- C2-1-P (MINECO/FEDER)., Peer reviewed

Between 30 June and 10 July 2013 we conducted a field experiment in central Spain to investigate the suitability of different plant species to attract ants as a tool used by European Honey buzzards (Pernis apivorus) in anting behaviour, under the assumption that buzzards would prefer easy-to-collect twigs from plants that effectively attract ants to perform anting behaviour. First, we estimated the strength needed to break 30 fresh twigs from the species that the buzzard used most frequently (maple tree), as well as from other abundant plants in the community, including rock rose, hawthorn, and Pyrenean oak. Second, we conducted a selection experiment at 23 random points to compare the effectiveness of ant attraction by these four species, measured as the total number of ants attracted, Peer reviewed
