These funds are intended at training of students with a pre-doctoral contract to conduct a PhD thesis in Centres of Excellence “Severo Ochoa”, including Doñana Biological Station (CSIC). The dissertations must be developed within research programs and human resources of the centres. The application can be done through electronic web of Ministry of Economy and Competitiveness (submission deadline September 19th). The total of 94 grants (6 for EBD) will have a duration of 4 years. This call has included the possibility to receive a full contract during the fourth year of the grant in case the student presents his/her dissertation in less than three years. informacion[at]
Climate change models predict sea level rise and increased intensity of storms and hurricanes in tropical sea turtle nesting areas. These factors could significantly increase beach inundation and erosion, thus affecting water content of sea turtle nesting beaches. A study was conducted of how sand water content is related to embryonic development and hatching success of leatherback turtle (Dermochelys coriacea) nests. However, both field and experimental studies revealed a strong negative correlation between sand water content and emergence success. Nests in wet sand suffered higher mortality, primarily in the earlier developmental stages. Eggs incubated in the driest sand lost mass, but there were no significant effects on hatchling mass or run speed compared to eggs that gained water during incubation. The results suggest that leatherback turtle nesting success should be expected to decrease. informacion[at] Patiño-Martinez et al (2014).

Counting rare and elusive animals and evaluating their demographic status, are fundamental yet challenging aspects of population ecology and conservation biology. This study has set out to estimate population size, genetic effective population size, sex ratio, and movements based on genetic tagging for the threatened Cantabrian capercaillie. Using genetic capture-mark-recapture, 93 individuals have been estimated in an area of about 500 km2, with sex ratio biased towards males. This capercaillie population is small and well within concern in terms of population viability. By genetic tagging, short movements have been mostly detected; just a few males were recaptured between contiguous display areas. Non-invasive surveys of endangered populations have a great potential, yet adequate sample size and location are key to obtain reliable information on conservation status. informacion[at] Morán-Luis et al (2014) Demographic status and genetic tagging of endangered Capercaillie in NW Spain.
