Illegal trade constitutes a major threat for a variety of wildlife. A criminology framework has been recently applied to parrot poaching in Mexico. This information has been analyzed, together with additional long-term data (1981–2005) on trade of the 22 Mexican parrot species. Parrot species widely differed in attractiveness to people, and their attractiveness strongly correlated with their prices both in the Mexican and US markets. The most attractive and valuable species (amazons and macaws) were disproportionally caught attending to the number of years they were legally trapped. The long-term cross-cultural preference for the most attractive species has led them to be among the most threatened species today. Socio-ecological work is needed to reverse the long-standing pet-keeping tradition that may decimate the most desired species in Neotropical countries. informacion[at]ebd.csic.es: Tella & Hiraldo (2014) Illegal and Legal Parrot Trade Shows a Long-Term, Cross-Cultural Preference for the Most Attractive Species Increasing Their Risk of Extinction.

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]ebd.csic.es

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]ebd.csic.es: Patiño-Martinez et al (2014).
