We present results and first epoch parsec-scale images from a monitoring program on five γ–ray loud blazars selected on the basis of their total flux density variability. We observed 0048−097, 0235+164, 0954+658, 1510−089 and 1749+096 with the Very Long Baseline Array simultaneously at 8.4 GHz and 22 GHz. Comparison between our high quality images and previous results from the literature sugges...
MAGIC has been performing optically triggered Target of Opportunity observations of flaring blazars since the beginning of its scientific operations. The alerts of flaring blazars originate from Tuorla blazar monitoring program, which started the optical monitoring of the candidate TeV blazars in 2002 and has now collected up to six years of data on 30 blazars. These Target of Opportunity obser...
Can Wide Consultation Help with Setting Priorities for Large-Scale Biodiversity Monitoring Programs?
Climate and other global change phenomena affecting biodiversity require monitoring to track ecosystem changes and guide policy and management actions. Designing a biodiversity monitoring program is a difficult task that requires making decisions that often lack consensus due to budgetary constrains. As monitoring programs require long-term investment, they also require strong and continuing su...
The Buck Creek-Boreas River Adirondack Watershed Monitoring Program, located in the region of New York State, United States, combines monitoring headwater streams, soils, and vegetation based on a watershed design. Continuous six watersheds is linked to sampling more than 400 additional streams between 2003 2019 for chemical analysis 14 constituents throughout highly valued ecoregion that cover...
Networks of marine reserves are increasingly a major component of many ecosystem-based management plans designed to conserve biodiversity, protect the structure and function of ecosystems, and rebuild and sustain fisheries. There is a growing need for scientific guidance in the design of network-wide monitoring programs to evaluate the efficacy of reserves at meeting their conservation and mana...
NICMOS foci are known to vary across detector's field of view. These variations must be taken into account when determining ''best'' focus from a particular stellar image. Focus field variations (FFV) may introduce substantial positional dependence in aperture corrections , thus they may also be important for high precision stellar photometry. In this report, we present empirical results of a s...
Transgenic cotton, Gossypium hirsutum L., lines expressing both Cry1F and Cry1Ac insecticidal proteins from Bacillus thuringiensis (Bt) have been commercially available in the United States since 2005. Both Bt proteins are highly effective against tobacco budworm, Heliothis virescens (F.), and other lepidopteran pests of cotton. Although CrylAc has been available in Bt cotton since 1996, the Cr...
A 3D marine seismic survey of the Odoptu license area off northeastern Sakhalin Island, Russia, was conducted by DalMorNefteGeofizika (DMNG) on behalf of Exxon Neftegas Limited and the Sakhalin-1 consortium during mid-August through early September 2001. The key environmental issue identified in an environmental impact assessment was protection of the critically endangered western gray whale (E...
Conceptual models are a key element of environmental monitoring programs. They integrate current understanding of system dynamics, identify important processes, facilitate communication of complex interactions, and illustrate connections between indicators and ecological states or processes. Well-constructed conceptual models provide a scientific framework for the monitoring program and justifi...
