“…Recently, the availability of food at rubbish dumps has been shown to drive sedentary behavior in previously migratory European white stork Ciconia ciconia [38] and brown bear Ursus arctos in Turkey and Romania [39], contributing to increases in the abundance of the stork and fragmentation of bear populations. There is strong policy pressure for the closure or covering of open landfill sites in the European Union (under the Landfill Directive 1993/31/EC), Turkey, and other parts of the world.…”

We present the results of our eighth annual horizon scan of emerging issues likely to affect global biological diversity, the environment, and conservation efforts in the future. The potential effects of these novel issues might not yet be fully recognized or understood by the global conservation community, and the issues can be regarded as both opportunities and risks. A diverse international team with collective expertise in horizon scanning, science communication, and conservation research, practice, and policy reviewed 100 potential issues and identified 15 that qualified as emerging, with potential substantial global effects. These issues include new developments in energy storage and fuel production, sand extraction, potential solutions to combat coral bleaching and invasive marine species, and blockchain technology. Aims of Horizon ScanningWe have conducted an annual horizon scan of global conservation issues since 2010 with the aim of highlighting, by consensus, emerging topics that are not yet widely known in the conservation community but could have substantial effects on biological diversity worldwide in the medium to long term. Our iterative, transferable process of horizon scanning, which is designed to be both transparent and democratic, is carried out by a team with a wide range of experiences and areas of expertise.Our aim has been to focus attention and stimulate debate about these subjects, potentially leading to new research foci, policy developments, or business innovations. These responses should help to facilitate better-informed forward-planning. It is difficult to gauge the direct effects of our horizon scans on the research, policy, or business communities, except through personal communication and hearsay. However, several topics recognized in our previous horizon scans Trends This is the eighth such annual horizon scan.An international team with expertise in horizon scanning, science communication, and conservation research, practice, and policy identified 15 issues, following widespread consultation and a Delphi-like scoring process to identify the most important.The issues were wide ranging, and include sand extraction, blockchain technology, use of robotics to combat invasive species, and new developments in energy storage and fuel production. There is now substantial action on this issue internationally, with several governments, including those of the USA and the UK, introducing legislative bans on microbeads in cosmetics and detergents, and many cosmetics companies voluntarily committing to halt their use of microplastics by 2020 [2,3]. New research on the effects of microbeads has revealed biological responses in both terrestrial and aquatic environments, with evidence demonstrating that microplastics reduce the survival and fitness of earthworms Lumbricus terrestris [4] and facilitate the accumulation of sorbed organic pollutants in fish [5]. Discussion of the use of gene editing to control invasive species or disease vectors, raised in our 2014 horizon scan [6], has increased...

“Closer‐to‐home” strategy benefits juvenile survival in a long‐distance migratory bird

Human‐induced changes in the climate and environment that occur at an unprecedented speed are challenging the existence of migratory species. Faced with these new challenges, species with diverse and flexible migratory behaviors may suffer less from population decline, as they may be better at responding to these changes by altering their migratory behavior. At the individual level, variations in migratory behavior may lead to differences in fitness and subsequently influence the population's demographic dynamics. Using lifetime GPS bio‐logging data from 169 white storks (Ciconia ciconia), we explore whether the recently shortened migration distance of storks affects their survival during different stages of their juvenile life. We also explore how other variations in migratory decisions (i.e., time, destination), movement activity (measured using overall body dynamic acceleration), and early life conditions influence juvenile survival. We observed that their first autumn migration was the riskiest period for juvenile white storks. Individuals that migrated shorter distances and fledged earlier experienced lower mortality risks. In addition, higher movement activity and overwintering “closer‐to‐home” (with 84.21% of the tracked individuals stayed Europe or North Africa) were associated with higher survival. Our study shows how avian migrants can change life history decisions over only a few decades, and thus it helps us to understand and predict how migrants respond to the rapidly changing world.

“…Por otro lado, el uso frecuente que las cigüeñas hacen de los vertederos supone a su vez una fuente potencial de contaminantes (Muñoz-Arnanz et al, 2011;de la Casa-Resino et al, 2014). Por ello, sería interesante estudiar el uso que la población navarra hace de los vertederos durante todo el año (ver Gilbert et al, 2016) y los efectos que ello pudiera tener sobre la salud de la población. Finalmente, entre las causas naturales de muerte detectadas en este y otros estudios cabe mencionar la muerte de pollos en nido por inclemencias meteorológias, sobre todo cuando ocurren periodos de fuertes lluvias durante las primeras semanas de vida de los pollos (abril y mayo) (Jovani & Tella, 2004).…”

ResumenEn las últimas décadas, la población reproductora de cigüeña blanca Ciconia ciconia L., 1758 en Navarra ha aumentado exponencialmente. La abundancia de comida predecible en vertederos, que proporcionan uno de los recursos tróficos más utilizados por la especie, parece haber tenido influencia tanto a nivel demográfico como en la distribución espacio-temporal en el conjunto de la península ibérica. Con el objetivo de estudiar los patrones de dispersión, movimientos y usos del hábitat de la población de cigüeñas en Navarra, durante el periodo 2012-2015 se anillaron 243 pollos en 9 colonias de cría del sur de Navarra. De todos ellos, el 16% de los individuos (n = 37) fue observado con posterioridad, tanto vivos y en buen estado (i.e., avistamientos) como muertos (i.e., recuperaciones, en su mayoría por electrocución). Todos los avistamientos, excepto tres, se realizaron en vertederos (n = 64), en donde el esfuerzo de muestreo fue considerablemente mayor. Dos avistamientos correspondieron a cigüeñas observadas en humedales, así como otro ejemplar que se observó dos años después en la colonia donde nació (i.e., reclutamiento). La distancia promedio de avistamiento en relación a la colonia de anillamiento fue de 48 km (distancia máxima, 410 km). La mayoría de avistamientos/recuperaciones se realizó durante la primavera y verano, con independencia de la edad. Todas las aves que se hallaron muertas (n = 7) fueron jóvenes encontrados en la proximidad de sus colonias de nacimiento.Palabras clave: Colonias, dispersión, electrocución, hábitat, vertederos. AbstractIn recent decades, the breeding population of White Stork Ciconia ciconia L., 1758 in Navarre has increased exponentially. The abundance of predictable food in landfills, providing one of the most used food resources for the species, seems to have influenced both demographically and spatiotemporal distribution in the whole Iberian Peninsula. In order to study dispersal patterns, movements and habitat use of the White Stork population in Navarre, during the period 2012-2015, we ringed 243 chicks in 9 breeding colonies in southern Navarre. Of these, 16% of the individuals (n = 37) were observed afterwards both alive and in good condition (i.e., sightings) and dead (i.e., recoveries), mostly by electrocution. All the sightings, except three, were made in landfills (n = 61), where the sampling effort was considerably higher. Two sightings corresponded to storks observed in wetlands, and another individual was observed two years after at the colony where it was born (i.e., recruitment). The average sighting distance in relation to the colony was 48 km (maximum distance, 410 km). Most sightings/recoveries were obtained during the spring and summer, regardless of age. All dead birds (n = 7) were fledglings found in the vicinity of the colonies where they were born.Key words: Colonies, dispersion, electrocution, habitat, landfills.
