Abstract Human‐wildlife conflicts (HWCs) are one of the most critical conservation challenges worldwide. Large carnivores frequently at centre these because perceived and real threats they pose to livestock human safety. Determining social perceptions attitudes towards plays a vital role in shaping policies that ensure sustainable coexistence humans wildlife. We conducted structured interviews with ranchers proposed Torres del Paine UNESCO Biosphere Reserve (Chilean Patagonia) 2011 2018....
Competition arises when two co-occuring species share a limiting resource. Potential for competition is higher have coexisted short time, as it the case herbivores and livestock introduced in natural systems. Sheep, late 19th century Patagonia, bear great resemblance size diet to guanaco, main native herbivore Patagonia. In such circumstances, could be expected that compete one of them displaced. We investigated spatial overlap habitat selection by coexisting sheep guanaco winter summer....
Habitat partitioning is a common ecological mechanism to avoid competition among coexisting species, and the introduction of new species into existing assemblages can increase competitive pressures. However, situations in allopatry sympatry only differing presence but not environmental conditions are scarce. Thus, discerning whether niche segregation arises from or different habitat preferences usually unfeasible. Here, we analyse species’ niches an assemblage native introduced herbivores...
On 17 January 1966, an accident during a refueling operation resulted in the destruction of air force KC-135 tanker and B-52 bomber carrying four thermonuclear weapons. Two weapons, whose parachutes opened, were found intact. The others experienced non-nuclear explosion with some burning release fissile fuel at impact. Joint efforts by United States Spain remedial action long-term program to monitor effectiveness cleanup. Air concentrations 239Pu 240Pu have been continuously monitored since...
Abstract Grouping behavior of social ungulates may depend on both predator occurrence and perceived predation risk associated with habitat structure, reproductive state, density conspecifics. Over 3 years, we studied grouping guanaco (Lama guanicoe) families in Chilean Patagonia during the birthing season determined their response to variation (habitat calf/adult rate, conspecifics). We considered effect two predators, puma (Puma concolor) culpeo fox (Lycalopex culpaeus). measured common...
Scientific evidence is scarce for the antimicrobial effect of copper on bacteria characterized as more resistant. Using Mycobacterium avium subsp. paratuberculosis (MAP), a highly resistant microorganism, pathogen model, ion treatment has shown significant bactericidal effect; however, sustainability MAP against toxicity was also reported in several studies. Accordingly, present study aimed to evaluate impacts MAP. This considered physicochemical properties and concentration buffer since it...
Background: Mycobacterium avium subsp. paratuberculosis (MAP) is the causal agent of paratuberculosis. This pathogen able to survive adverse environmental conditions, including pasteurization process. Copper, a well-studied metal, considered an important antibacterial tool, since it has been shown inactivate even MAP in treated milk through unknown mechanisms. The aim present study show effect copper ions, and reactive oxygen species (ROS) generated response oxidative stress, on damage DNA...

The transition from fossil fuels to renewable energy sources is fundamental mitigate the effects of global climate change. Renewable power capacity increasing globally, and solar photovoltaic will be dominant source by 2050. Photovoltaic parks require great extensions land, usually in drylands. But both ecosystems created effect on are scarcely studied. This paper reviews current knowledge impact production arid semiarid describes structure functioning these novel ecosystems, including...
Abstract Social prey species respond to predation risk by modifying habitat selection and grouping behaviour. These responses may depend on both actual (predator probability of occurrence) and/or perceived associated with structure. Other factors like food availability co‐occurrence other also affect group formation. We analyse behaviour (group size cohesion) lesser rhea ( Rhea pennata subsp. ), a ratite endemic South America inhabiting steppe shrublands grasslands, in relation (puma...
Abstract Aim: the aim of present study is to show what effect copper ions, and ROS generated in response oxidative stress, on damage MAP DNA when exposed a ion challenge cow's milk. Methods Results: spiked milk with different bacterial loads was supplemented blocking agents. These were either chelators EDTA BCS or reactive oxygen species (ROS) quenchers D-mannitol, gallic acid quercetin. protection, viability production after exposure then measured. In load 10 4 cells mL -1 , both all...
