This dataset compiles information obtained during the cruise BOCATS 2016, This dataset gathers discrete measurements of CO2 (pH and alkalinity) and hydrographic variables (salinity, temperature, dissolved oxygen, nitrate, phosphate and silicate) obtained during the cruise BOCATS carried out along the OVIDE section from 17 June to 31 July 2016.
pH was measured spectrophotometrically following the Clayton and Byrne (1993). This method consists on adding a dye solution to the seawater sample, so that the ratio between two absorbances at two different wavelengths is proportional to the sample pH.
Alkalinity was measured using an automatic potentiometric titrator Titrando 809 Metrohm, with a Metrohm 6.0232.100 combination glass electrode and a Pt-1000 probe for temperature measurement following the methodology given by Pérez and Fraga (1987).
Dissolved oxygen was analyzed following the widely applied Winkler method.
Determinations of nitrate, phosphate and silicate were carried out following methods described by Hansen and Grassoff (1983)
Salinity and Temperature were recorded with a CTD probe, BOCATS (CTM2013-41048-P), No

SEMILLAS DE RICINUS COMUNIS RECOGIDAS EN DOCE POBLACIONES EN TÚNEZ
- Saadaoui, Ezzeddine
- Martín Gómez, José Javier
- Cervantes, Emilio
Images of the seeds were obtained with a scanner ScanJet 5300 C (HP). A list attached includes exact locations where seeds were gathered. This dataset is under a Creative Commons Attribution-Non commercial 4.0 International License., Castor bean (Ricinus communis L.) is the unique species of the genus Ricinus in the family Euphorbiaceae. Traditionally used in agriculture, the seeds are a source of lipid reserves, secondary metabolites and fuels in the pharmaceutic and oil industry. The first mention of Ricinus communis as a laxative can be traced back to 3500 year-old Egyptian papyrus scrolls. The seeds are poisonous containing 2.8–3% toxic substances such as ricin, a potent inhibitor of protein synthesis, and agglutinin-1.
Seed morphology may give information useful in the phenotypic characterization and phylogenetic relationships between varieties and cultivars. The seeds are characterized by high variability essentially in colour, size, weight and shape. Colour varies from red, white, grey, faint chocolate to purple and high variation is exhibited by the surface area, hundred-seed weight showed a wide range of variation from 11.6 to 59.1 g.
Accurate geometric description of seeds requires the comparison with geometric figures that resemble seed images. The approach has been developed in the model plant (Arabidopsis thaliana) as well as in the model legumes, Lotus japonicus and Medicago truncatula. In Capparis spinosa the comparison of seed images with the cardioid curve was helpful to describe differences between two subspecies.
In R. communis, high phenotypical variability is observed in the seeds, that also represent the interesting part of plant, as oil source. In the analysis of seed shape, the model applied for the geometric description has been an ellipse., Funded through a cooperation between IRNASA-CSIC and National Institute of Research in Rural Engineering, Waters and Forests (INRGREF), University of Carthage, Tunisia., Peer reviewed

The ecological role of species can vary among populations depending on local and regional differences in diet. This is particularly true for top predators such as the bottlenose dolphin (Tursiops truncatus), which exhibits a highly varied diet throughout its distribution range. Local dietary assessments are therefore critical to fully understand the role of this species within marine ecosystems, as well as its interaction with important ecosystem services such as fisheries. Here, we combined stomach content analyses (SCA) and stable isotope analyses (SIA) to describe bottlenose dolphins diet in the Gulf of Cadiz (North Atlantic Ocean). Prey items identified using SCA included European conger (Conger conger) and European hake (Merluccius merluccius) as the most important ingested prey. However, mass-balance isotopic mixing model (MixSIAR), using δ13C and δ15N, indicated that the assimilated diet consisted mainly on Sparidae species (e.g. seabream, Diplodus annularis and D. bellottii, rubberlip grunt, Plectorhinchus mediterraneus, and common pandora, Pagellus erythrinus) and a mixture of other species including European hake, mackerels (Scomber colias, S. japonicus and S. scombrus), European conger, red bandfish (Cepola macrophthalma) and European pilchard (Sardina pilchardus). These contrasting results highlight differences in the temporal and taxonomic resolution of each approach, but also point to potential differences between ingested (SCA) and assimilated (SIA) diets. Both approaches provide different insights, e.g. determination of consumed fish biomass for the management of fish stocks (SCA) or identification of important assimilated prey species to the consumer (SIA)., The study was funded by Fundación Loro Parque, CEPSA (Compañía Española de Petroleos S.A.), EcoCet Project [CGL2011-25543] J.G. and R.dS. were funded by the Spanish Ministry of Economy and Competitiveness through the Severo Ochoa Programme for Centres of Excellence in R+D+I [SEV-2012-0262].

SEASONAL AND CIRCADIAN BIASES IN BIRD TRACKING WITH SOLAR GPS-TAGS [DATASET]
- Silva, Rafa
- Afán, Isabel
- Gil, Juan A.
- Bustamante, Javier
Global Positioning System (GPS) tags are nowadays widely used in wildlife tracking. This geolocation technique can suffer from fix loss biases due to poor satellite GPS geometry, that result in tracking data gaps leading to wrong research conclusions. In addition, new solar-powered GPS tags deployed on birds can suffer from a new “battery drain bias” currently ignored in movement ecology analyses. We use a GPS tracking dataset of bearded vultures (Gypaetus barbatus), tracked for several years with solar GPS tags, to evaluate the causes and triggers of fix and data retrieval loss biases. We compare two models of solar GPS tags using different data retrieval systems (Argos vs GSM-GPRS), and programmed with different duty cycles. Neither of the models was able to accomplish the duty cycle programed initially. Fix and data retrieval loss rates were always greater than expected, and showed non-random gaps in GPS locations. Number of fixes per month of tracking was a bad criterion to identify tags with smaller biases. Fix-loss rates were four times higher due to battery drain than due to poor GPS satellite geometry. Both tag models were biased due to the uneven solar energy available for the recharge of the tag throughout the annual cycle, resulting in greater fix-loss rates in winter compared to summer. In addition, we suggest that the bias found along the diurnal cycle is linked to a complex three-factor interaction of bird flight behavior, topography and fix interval. More fixes were lost when vultures were perching compared to flying, in rugged versus flat topography. But long fix-intervals caused greater loss of fixes in dynamic (flying) versus static situations (perching). To conclude, we emphasize the importance of evaluating fix-loss bias in current tracking projects, and deploying GPS tags that allow remote duty cycle updates so that the most appropriate fix and data retrieval intervals can be selected., No

HOW WILL CLIMATE CHANGE AFFECT ENDANGERED MEDITERRANEAN WATERBIRDS?
- Ramírez Benítez, Francisco
- Rodríguez, Carlos

- Figuerola, Jordi
- Bustamante, Javier
Global warming and direct anthropogenic impacts, such as water extraction, are largely affecting water budgets in Mediterranean wetlands, thereby increasing wetland salinities and isolation, and decreasing water depths and hydroperiods (duration of the inundation period). These wetland features are key elements structuring waterbird communities. However, the ultimate and net consequences of these dynamic conditions on waterbird assemblages are largely unknown. We combined a regular sampling on waterbird presence through the 2008 annual cycle with in-situ data on these relevant environmental predictors of waterbird distribution to model habitat selection for 69 individual species in a typical Mediterranean wetland network in south-western Spain. Species association with environmental features were subsequently used to predict changes in habitat suitability for each species under three climate change scenarios (encompassing changes in environment that ranged from 10% to 50% change as predicted by climatic models). Waterbirds distributed themselves unevenly throughout environmental gradients and water salinity was the most important gradient structuring the distribution of the community. Environmental suitability for the guilds of diving birds and vegetation gleaners will be reduced according to future climate scenarios, while most small wading birds will benefit from changing conditions. Resident species and those that breed in this wetland network will be also more impacted than those using this area for wintering or stopover. We provide here a tool that can be used in a horizon-scanning framework to identify emerging issues on waterbird conservation and to anticipate suitable management actions, Peer reviewed

THE IMPORTANCE OF INCLUDING SURVIVAL RELEASE COSTS WHEN ASSESSING VIABILITY IN REPTILE TRANSLOCATIONS [DATASET]
- Bertolero, Albert
- Pretus, Joan Lluís
- Oro, Daniel
Datasets supporting the results of the article “The importance of including survival release costs when assessing viability in reptile translocations”. The readme files contain information about each data column. Questions should be addressed to Albert Bertolero (albert.bertolero@gmail.com)., Translocations to restore populations of endangered species are an important conservation tool, but a reliable diagnosis is needed to assess their success. We used capture-recapture modeling to analyze the adult apparent survival of released and resident tortoises in two translocation projects in Spain monitored for 14 and 29 years. We tested if long-term survival rates differ between released and resident individuals, if survival was lower during the phase of establishment (i.e. release cost), how long acclimation lasts and if increased density due to releases affects survival. We found lower survival of released tortoises during the phase of establishment (1 to 3 years) when residents were already present. After establishment, survival was very high and unaffected by density-dependence. Body condition before release was similar between recaptured and dead/missing tortoises, and did not predict establishment survival. Stochastic population viability analysis showed that success when releasing small numbers of individuals strongly depends upon adult long-term survival. Release of small second batches of tortoises was not sensitive to a growing population, regardless of its release timing. Our results highlight long-term survival as crucial in translocation projects of long-lived species, invalidating short-term (first year) survival assessment, when survival release cost does not match long-term survival. A release cost of different duration should be included in model estimation before modeling predictions. Releasing tortoises (for welfare of captive individuals or for mitigating human negative impacts) in an already established population is not recommended under most circumstances. Acclimation cost is followed by survival approaching wild counterparts. If this milestone is not achieved, the project needs to be carefully assessed to adopt other management options or should be stopped altogether., Field work in the Ebro Delta and Minorca was partially funded by the Ebro Delta Natural Park, the Generalitat de Catalunya, the Institut Menorquí d'Estudis (IME), the Consell Insular de Menorca and the Spanish Ministry of Science and Technology (CICYT CGL2004-0473/BOS)., Peer reviewed

- Pérez, Ricardo
- Bazaga, Pilar
This contains three Microsoft Excel files for global methylation, AFLP and MSAP data, respectively. On each file one sheet contains the information of maternal plants and the other the information of the offspring. Each row refers to individual samples. For AFLP and MSAP each column refers to specific (although anonymous) markers labeled similarly in both sheets.
Leaves from 15 adult plants were sampled along a 125-m transect in Cuevas Bermejas population (Sierra de Cazorla, Jaén Province, southeastern Spain), in October 2015. Offspring were obtained from seeds under greenhouse conditions, leaf samples were collected when they were 8-months old when only offspring of 13 mothers remained. DNA was extracted from leaves using Qiagen DNeasy Plant Mini Kit and the manufacturer protocol.
Maternal parents and greenhouse plants were genetically fingerprinted using amplified fragment polymorphism (AFLP) markers. The AFLP and MSAP analysis were performed using standard protocols involving the use of fluorescent dye-labeled selective primers. For AFLP, each plant was fingerprinted using three different EcoRI + 3 / MseI + 3 primer pair combinations. MSAP assays used four HpaII-MspI + 2 / MseI + 3 primer combinations. In the two analyses fragment separation and detection was made using an ABI PRISM 3130xl DNA sequencer, only fragments ≥ 150 base pairs in size were considered and the presence (1) or absence (0) of fragments in each sample was scored manually by visualizing electropherograms with GeneMapper 3.7 software, This dataset includes (i) global DNA cytosine methylation estimates (= percentage of all genomic cytosines that are methylated) obtained by reverse phase HPLC with spectrofluorimetric detection, (ii) the scoring (presence/absence) of individual genetic markers (AFLP), and (iii) the scoring (presence/absence) of individual epigenetic markers (MSAP) in maternal plants of the shrub Lavandula latifolia and their greenhouse-grown offspring., Peer reviewed

Genotypes (9 microsatellite loci) of breeding Common quails (Coturnix coturnix) and their offspring sampled in Northeast Spain for paternity analyses. These genotypes were studied in the article Sanchez-Donoso I, Vilà C, Puigcerver M, Rodríguez-Teijeiro JD. Mate guarding and male body condition shape male fertilization success and female mating system in the Common Quail. Animal Behaviour, in press. In this study, we investigated female mate choice and male fertilization success in the Common quail by monitoring adult quails and assigning genetic paternity of their offspring. First we described the female mating system and the factors associated with it. Second we studied the relationship between male fertilization success and pair-bond order, pair-bond duration and male body condition. Finally, we explored whether male body condition shapes the male trade-off between mate guarding or looking for new mates., Peer reviewed
