A new species within the genus Liolaemus from southeast Argentine Patagonia is described. This new taxon, Liolaemus yatel sp. nov., presents anatomical traits shared with the Liolaemus lineomaculatus section within the Liolaemus lineo-maculatus group. However, Liolaemus yatel sp. nov. does not exhibit trifid dorsal scales, which is a diagnostic character of the L. lineomaculatus group. Moreover, this new species differs from other taxa of the L. lineomaculatus group in that dorsal and nuchal scales either completely lack keels or are slightly keeled. Additionally, the presence of trifid scales in Liolaemus magellanicus was recorded, another species included in the L. lineomaculatus section. These findings provide additional information for the study of evolutionary relationships among the species of the L. lineomaculatus section, especially the establishment of their diagnostic character status. informacion[at]ebd.csic.es: Abdala et al (2014) New Patagonian species of Liolaemus (Iguania: Liolaemidae) and novelty in the lepidosis of the southernmost lizard of the world: Liolaemus magellanicus.

A severe ecological perturbation caused by artificial lights is mass mortalities of organisms, including seabird fledglings that are attracted to lights at night on their first flights to the sea. During a 15-year period, the number of fledging short-tailed shearwaters Ardenna tenuirostris found grounded in evening and morning at Phillip Island, Australia, has been reported. Factors as date, moon phase, wind direction and speed, number of visitors and holiday periods were assessed. Light-induced mortality of seabirds is usually underestimated. More birds (dead and alive) were rescued in peak fledging, moonless and windy nights. Mortality increased through the fledging period, in the mornings and with increased traffic on holiday periods. While moon, wind and time are uncontrolled natural constraints, this study demonstrated that reduction of light pollution and better traffic management can mitigate artificial light-induced mortality. informacion[at]ebd.csic.es: Rodríguez et al (2014) Fatal attraction of short-tailed shearwaters to artificial lights.

Aerial surveys of aquatic birds at Doñana is a new publication within the CSIC book collection dedicated to outreach. The publication was prepared for the 50th Anniversary of EBD. The origin of the Doñana Biological station (EBD-CSIC) is found in the attempt to preserve the marshes of the Guadalquivir river, one of the most important wetlands in Europe. EBD is a pioneer in Spain in collecting biodiversity data, especially on fauna. Thousands of data have been accumulated in field notebooks, and their exceptional value has been revived later when they have been computerized and made public on the internet. Aerial surveys at Doñana have had a particular treatment almost from the beginning, maintaining a visit routine and a record of the locations that were surveyed, used to recover the sampling effort in retrospect and built a database covering 40 years of bird counts. informacion[at]ebd.csic.es
