Ground‐truthing of satellite imagery to assess seabird colony size: A test using Adélie penguins

Remote Sensing in Ecology and Conservation, EarlyView.
Adélie penguin colony size can be estimated from space using very high‐resolution (VHR; 0.3–0.6 m resolution) satellite imagery due to the contrast between their guano stain and the surrounding terrain. Our study assessed the utility of VHR imagery for making indirect assessments of changes in colony size.

Two‐Stage Isothermal Transformation of Austenite into Nanobainite in a Chemically Inhomogeneous Medium‐Alloy Steel Containing 0.5 wt% C

steel research international, EarlyView.
The effect of chemical inhomogeneity on the microstructure and properties of nanobainitic steel is investigated. A two‐stage isothermal heat treatment that produced a more uniform microstructure is designed. The first‐stage temperature is higher than the MS of depleted bands; conversely, the second‐stage temperature is lower than the first‐stage ...

Spraying drones: efficacy of integrating an avian repellent with drone hazing to elicit blackbird flock dispersal and abandonment of sunflower fields

Wildlife Biology, EarlyView.
Multiple management strategies exist to combat bird damage to agriculture. We explored combining two tools, drones as frightening devices and an avian repellent, to assess effectiveness of an integrated method to deter large flocks on complex landscapes. We evaluated the ability of a spraying drone (DJI Agras MG‐1P) deploying Avian Control (i.e. active

Evaluation of drones as a tool for multi‐species nest surveys on linear rights‐of‐way

Wildlife Society Bulletin, EarlyView.
This paper examines the use of drones with infrared cameras as a tool in the detection of bird nests on linear rights‐of‐way, in comparison to standard ground‐based nest surveys. Abstract The varying application of drone use in wildlife research has expanded in recent years. With the ability to utilize a variety of different sensors (e.g., infrared [IR]

Interspecific variation in leaf phenology and its relationship with plant traits in a seasonal tropical forest

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Leaf phenology plays an important role in plant life‐history strategies and in determining ecosystem‐level fluxes of carbon and water. In seasonal tropical forests, leaf phenology is highly variable among tree species, but limited quantitative data have hindered our ...

Harvesting benefits: Exploring the effects of second‐best policies on enhancing soil organic carbon stocks in agriculture

American Journal of Agricultural Economics, EarlyView.
Abstract Agricultural subsidies can be an effective policy tool to enhance soil organic carbon sequestration. This paper assesses the effectiveness of a second‐best hypothetical policy which subsidizes additional canola hectares optimally for each soil zone in Saskatchewan in an effort to increase soil organic carbon.

Arianna's Palette: A Diagnostic Study of the Painting Walls of the Domus of Arianna in Pompeii

Archaeometry, EarlyView.
ABSTRACT The House of Arianna, also known as the House of Colored Capitals, represents, with its 1700 m2 of floor space, one of the most majestic examples of a residence within the Pompeii archaeological site. The research developed within the project “Cultural Heritage Active Innovation for Sustainable Society—CHANGES” reports the outcomes of the ...

Linear-time algorithms for weakly-monotone polygons

Computational Geometry, 1993
Triangulating a simple polygon is possible in linear time. But the corresponding algorithm is too complex to be considered practical. Simple optimal algorithms for special classes of polygons are interesting. The author studies a new class of so-called weakly-monotone polygons which contains the monotone class.

Drones: Emergence of a transformative technology for island rodent eradications

Conservation Science and Practice, EarlyView.
Drones have emerged as a potentially powerful tool to address an ongoing need for alternative rodent eradication solutions on remote islands. This potential has now been demonstrated in a diverse set of operations across the Pacific. In the coming decades, this novel toolset also offers the possibility to step beyond existing paradigms and imagine a ...
