Accounting for animal movement during aerial imaging surveys

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Animals are not stationary during aerial surveys; if their movements are related to the movement of the aerial platform, then bias can be introduced into subsequent population count estimates. We sought to establish a framework for assessing the impacts of animal movement on count error and platform bias by comparing aggregated counts and relative ...

A Comparison of Mobile Laser Scanning Data Acquisition Methods in Closed Forest, Open Woodland and Sub‐Alpine Woodland Ecosystems

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that the mobile laser scanning (MLS) sampling density required to reliably characterise vegetation structure increases with a site's structural complexity. Applying a five‐level acquisition framework across open woodland, closed forest and sub‐alpine woodland ecosystems, we found that longer scanning paths increased the ...

From Green Strategy to Sustainable Development: Corporate Efforts Toward SDG 12 and SDG 13

open access: yesSustainable Development, EarlyView.
ABSTRACT Firms are increasingly integrating United Nations Development Goals 12 (Responsible consumption and production) and 13 (Climate action) as a part of their sustainability strategies. However, prior research has rarely examined how these SDGs interact as a unified capability rather than as isolated practices.

Understanding Interactions Between Sustainable Development Goals Within and Between Policy Programmes: The Case of Kenya's Dairy Sector

open access: yesSustainable Development, EarlyView.
ABSTRACT Achieving Agenda 2030 depends on addressing interactions between the sustainable development goals (SDGs). In this paper, we conceptualize SDG interactions as synergies or trade‐offs, incoming or outgoing, and internal or external, and analyze how SDG 2 (Zero Hunger) interacts with other SDGs within and across policy programmes that support ...

Translocation of Florida Sandhill Cranes to Georgia

open access: yes, 2001
Wild Florida sandhill cranes (Grus canadensis pratensis) were captured in Florida during 3 years and translocated to Grand Bay Wildlife Management Area (GBWMA), Georgia, in an attempt to establish a resident population of Florida sandhill cranes in a ...

From Proxies to System State: Defining Sustainability Management Against Symbolic Progress

open access: yesSustainable Development, EarlyView.
ABSTRACT Sustainability in management is often measured through scores, ratings, and disclosure narratives that can reward symbolic progress while leaving underlying social‐ecological conditions unchanged. This perspective paper offers a definition of Sustainability Management as how organizations plan, organize, lead, and control (four management ...
