Identifying potential areas of expansion for the endangered brown bear (Ursus arctos) population in the Cantabrian Mountains (NW Spain)

Many large carnivore populations are expanding into human-modified landscapes and the subsequent increase in coexistence between humans and large carnivores may intensify various types of conflicts. A proactive management approach is critical to successful mitigation of such conflicts. The Cantabrian Mountains in Northern Spain are home to the last remaining native brown bear...

Patterns of wild carnivore attacks on humans in urban areas

Attacks by wild carnivores on humans represent an increasing problem in urban areas across North America and their frequency is expected to rise following urban expansion towards carnivore habitats. Here, we analyzed records of carnivore attacks on humans in urban areas of the U.S. and Canada between 1980 and 2016 to analyze the general patterns of the attacks, as well as...

Making Ostrom’s framework applicable to characterise social ecological systems at the local level

Ostrom’s framework to analyse the sustainability of social-ecological systems has attracted great interest in the last years. It was not conceived to characterise systems, but its nature and structure make it very appealing to be used with this objective. However, its use to characterise three social-ecological systems where common-pool resource management is central created some...

Subtle Gardeners: Inland Predators Enrich Local Topsoils and Enhance Plant Growth

Inland vertebrate predators could enrich of nutrients the local top soils in the area surrounding their nests and dens by depositing faeces, urine, and prey remains and, thus, alter the dynamics of plant populations. Surprisingly, and in contrast with convincing evidence from coastal habitats, whether and how this phenomenon occurs in inland habitats is largely uncertain even...

Genetic Signatures of Demographic Changes in an Avian Top Predator during the Last Century: Bottlenecks and Expansions of the Eurasian Eagle Owl in the Iberian Peninsula

The study of the demographic history of species can help to understand the negative impact of recent population declines in organisms of conservation concern. Here, we use neutral molecular markers to explore the genetic consequences of the recent population decline and posterior recovery of the Eurasian eagle owl (Bubo bubo) in the Iberian Peninsula. During the last century, the...

Population Characteristics May Reduce the Levels of Individual Call Identity

Individual variability influences the demographic and evolutionary dynamics of spatially structured populations, and conversely ecological and evolutionary dynamics provide the context under which variations at the individual level occur. Therefore, it is essential to identify and characterize the importance of the different factors that may promote or hinder individual...

Moonlight Makes Owls More Chatty

Background Lunar cycles seem to affect many of the rhythms, temporal patterns and behaviors of living things on Earth. Ambient light is known to affect visual communication in animals, with the conspicuousness of visual signals being largely determined by the light available for reflection by the sender. Although most previous studies in this context have focused on diurnal light...

La aplicación de gallinazas en sorgo forrajero como cultivo energético

Forage sorghum could be an efective alternative crop for energy purposes in areas where water irrigation are limited. The ability of regrowth after cutting of this crop can enhance biomass production. The sorghum stems sugar content could be an added value for bioethanol production. Trial was carried out in a greenhouse with forage sorghum (Sorghum bicolor (L.) Moench) cv...
