AltresBulwer's petrel Capture-Mark-Recapture data(2021-01-04) Cruz Flores, Marta; Pradel, Roger; Bried, Joël; González-Solís, Jacob; Ramos i Garcia, RaülBulwer’s petrel captures from 2007 to 2018 specifying the reproductive performance/status of the individuals (1=unknown reproductive performance, 2=successful breeder, 3=failure at incubation, 4=failure at chick-rearing, 5=non-breeder and 6=breeder with unknown reproductive performance), their colony (Vila or Montaña Clara) and their sex (0=not sexed, 1=male and 2=female). Data from Vila islet in Azores Islands were collected from 2007 to 2012 and in 2016; data from Montaña Clara islet in Canary Islands were collected from 2010 to 2018.- AltresSexual segregation in the foraging behaviour of a slightly dimorphic seabird: influence of the environment and fishery activity (Raw data)(2020-11) Reyes-González, José Manuel; Felipe, Fernanda de; Morera Pujol, Virginia; Soriano Redondo, Andrea; Navarro Herrero, Leia; Zango, Laura; García Barcelona, Salvador; Ramos i Garcia, Raül; González-Solís, JacobDades d'isòtops estables referents a la recollida de sang (plasma) de l'espècie Scopoli's shearwater Calonectris diomedea, durant l'època de cría dels anys 2012, 2014, 2014 i 2015 a la colònia de Cala Morell, Menorca, Illes Balears
- ArticleCrossing the Pillars of Hercules: Understanding transoceanic migrations of seabirds throughout their breeding range(John Wiley & Sons, 2019-02-28) Ramos i Garcia, RaülVariability in long‐distance migration strategies is still poorly understood due to the fact that individuals are often tracked from a single colony/population. Transoceanic migrations of Scopoli's shearwaters (Calonectris diomedea) across the Strait of Gibraltar (SoG) have been tracked from several breeding colonies isolatedly, and factors related to the variability in phenological schedules among different populations remain, therefore, not well‐understood. Using light‐level geolocator data, I examined the autumn (postbreeding) and spring (prebreeding) migratory passage dates through SoG of four populations of Scopoli's shearwater spread along the longitudinal breeding range of the species. Additionally, I also estimated the at‐sea activity patterns (from immersion data) during both migratory passages, as well as the body size (from morphometric data) of the individuals of these populations. On average, Scopoli's shearwaters leave the Mediterranean (cross SoG) on 31 October ± 1.8 days on its autumn migrations and return on 03 March ± 1.6 days on its spring migrations. At the population level, there was a clear gradient in the timing of crossing SoG: birds from the westernmost populations (Murcia, SE Spain) were the first ones in leaving the Mediterranean while easternmost breeders (Paximada, Crete) were the last ones. In spring, only birds from the largest breeding population (Zembra, Tunisia) seemed to advance their return and crossed SoG significantly earlier than birds tracked at the remaining populations. In both passages, shearwaters from central and eastern populations spent more time flying than their conspecifics from the western Mediterranean. Scopoli's shearwater populations display a differential phenology and behavior in their migratory passages through SoG. The longitudinal gradient in body size already reported for the species could be an evolutionary response to an obvious trade-off between sharing common wintering grounds in the Atlantic Ocean and the temporal constraints of restoring physiological condition in those grounds.
- AltresDoes sexual segregation occur during the non-breeding period?: A comparative analysis in spatial and feeding ecology of three Calonectris shearwaters (Raw data)(2019-07-10) Felipe, Fernanda de; Reyes-González, José Manuel; Militão, Teresa; Neves, Verónica C.; Bried, Joël; Oro, Daniel; Ramos i Garcia, Raül; González-Solís, JacobWe evaluated the degree of sexual segregation (SS) in the feeding ecology, in the choice of main non-breeding areas, in behaviour and in migratory phenology of three closely related shearwaters: Scopoli’s, Cory’s and Cape Verde shearwaters (Calonectris diomedea, C. borealis and C. edwardsii, respectively) during the non-breeding period in relation to the conditions of their different life strategies. The main objective of the study is to better understand the ecological and evolutionary role of sex on the spatial, behavioural and feeding ecology of birds during the non-breeding period, since most studies on birds have focused on the breeding period. The referred issues were addressed through a multidisciplinary approach combining geolocation and stable isotope data.
