Title Absolute photometry and Night Sky Brightness with all-sky cameras Type Report
Year 2013 Publication e-prints Complutense Abbreviated Journal e-prints Complutense
Volume Issue 24626 Pages
Keywords Instrumentation; skyglow; measurement; modeling
Abstract All-sky cameras have proven to be powerful tools to continuously monitoring the sky in a wide range of fields in both Astrophysics and Meteorology. In this work, we have developed a complete software pipeline to analyze the night CCD images obtained with one of such systems. This let us to study typical parameters used in Astrophysics to characterize the night sky quality, such as the Sky Brightness, the Cloud Coverage and the Atmospheric Extinction, how they evolve over the time and their variability. Using our software, we analyzed a large set of data from AstMon-OT all-sky camera at Teide Observatory. Results from this work have been applied in the support to the spanish CTA site proposal at Izaña, Tenerife and are being discussed within the CTA consortium. A comparison with data from other devices that have been used in site characterization such as the IAC80 telescope is also presented. This comparison is used to validate the results of the analysis of all-sky images. Finally, we test our software with AstMon-UCM and DSLR cameras. Some general recommendations for the use of DSLR cameras are provided.

Title Responses to direct versus indirect cues of predation and competition in naϊve invasive mice: implications for management Type Journal Article
Year 2013 Publication New Zealand Journal of Ecology Abbreviated Journal NZ J. of Ecol.
Volume 37 Issue 1 Pages 33-40
Keywords Animals; Mus musculus; mice; New Zealand; foraging; moonlight; giving-up density; GUD; moon phase
Abstract Many populations of invasive mice Mus musculus in New Zealand have experienced the removal of mammalian predators and competitors, with the consequence of mouse population irruptions. The effects of these removals on mouse foraging are largely unknown, yet this information is essential for developing and implementing better mouse control. We investigated the effects of direct and indirect predatory cues on foraging of free-ranging mice at a site where mammalian predators were eradicated 5 years previously. We used 17 stations, each containing four trays of millet seeds mixed thoroughly in sand, with three unfamiliar mammalian (a predator, a competitor, and a herbivore) odour treatments and a control (water), during the four phases of the moon. We measured mouse selectivity for treatment/control trays, giving-up densities (GUDs, a measure of food consumption), and tray encounter rates. Foraging by mice was not affected by odour cues from any of the unfamiliar mammals. Moonlight intensity, however, affected mouse foraging, with higher GUDs being recorded on brighter moon phases (full and waxing > new and waning) during the first night of the trials. This effect was less pronounced during the second night. Resource encounter rates were also affected, with the proportion of trays foraged lower during the brighter phases of the moon on both the first and second nights. We suggest that coordinating management efforts according to the phases of the moon has the potential to improve mouse control and reduce bait wastage.
