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

This dataset supports the article “Productivity is related to nest site protection and nesting substrate in a German Osprey population” published in Journal of Ornithology. In this article, during the years 2000-2009, we investigated the productivity in relation to the nesting substrate (artificial structures or trees) and the protection status of the nest location (inside or outside protected areas) in the eastern German population of Ospreys. The readme text file attached provides information about the header cells in the dataset., Peer reviewed

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

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
