Genetic structure of the threatened West-Pannonian population of Great Bustard (Otis tarda)
The genetic diversity, population structure and gene flow of the Great Bustards (Otis tarda) living in Austria-Slovakia-West Hungary (West-Pannonian region), one of the few populations of this globally threatened species that survives across the Palaearctic, has been assessed for the first time in this study. Fourteen recently developed microsatellite loci identified one single population in th...
متن کاملHabitat Suitability Modeling of Great Bustard, Otis tarda, using ENFA and GIS
During the last century, the global population of the Great Bustard (Otis tarda) has decreased and this species is now considered vulnerable. In Iran, the status of this species is much more critical and its distribution is limited to a few areas of Bukan county. We modeled the suitability of habitat for Great Bustards in Bukan County with the goal of determining the most important of distribut...
متن کاملEffects of great bustard (Otis tarda) gut passage on black nightshade (Solanum nigrum) seed germination
Birds are important seed dispersers for fleshy fruits through their transportation of ingested seeds. The seeds of many species germinate faster and in greater proportions after passing through a digestive tract, although the effects of this passage vary amongst bird and plant species. Many factors determine the germination success of ingested seeds, such as seed scarification during the digest...
متن کاملMeta‐barcoding insights into the spatial and temporal dietary patterns of the threatened Asian Great Bustard (Otis tarda dybowskii) with potential implications for diverging migratory strategies
Food resources are often not sufficient to satisfy the nutritional and energetic requirements during winter conditions at high latitudes. Dietary analysis is a prerequisite to fully understanding the feeding ecology of a species and the nature of trophic interactions. Previous dietary studies of Asian Great Bustard (Otis tarda dybowskii) relied on behavioral observations, resulting in categoriz...

Resumen.—Otis tarda es el ave con mayor dimorfismo sexual y una de las de mayor peso entre las que conservan la capacidad de vuelo. Los machos adultos capturados en España fueron 2.48 veces más pesados que las hembras y sus medidas lineales un 18–30% mayores que las de las hembras. Entre finales del invierno y la estación reproductiva el peso medio aumentó en un 16% en las hembras y en un 20% e...
