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

open access: yesWildlife 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]

Estimation of weed distribution for site-specific weed management—can Gaussian copula reduce the smoothing effect?

open access: yesPrecision Agriculture
Creating spatial weed distribution maps as the basis for site-specific weed management (SSWM) requires determining the occurrence and densities of weeds at georeferenced grid points. To achieve a field-wide distribution map, the weed distribution between

The Consequences of Soil Organic Carbon for Crop Yield, Farm Productivity and Profit

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Crop choices affect soil organic carbon (SOC) stocks, allowing farmers to manipulate the amount of carbon sequestered in the soil over time. This paper examines the private and public benefits of crop rotations that sequester additional carbon across the province of Saskatchewan, Canada using a novel field‐level dataset from the Saskatchewan ...

Imagination in Critical Theory: Utopia, Ideology, Aesthetics

open access: yesConstellations, EarlyView.
ABSTRACT This article explores the role of imagination in critical theory, addressing its conceptual ambiguity and its synthesis of three distinct but interrelated strands. The first, rooted in Freud's theory, sees imagination as wish‐fulfillment—necessarily unreal yet foundational to utopian thought.
