Mind the gap, exploring the expectation gap in political leadership in disasters: An Australian case study 注意差距——探究灾害中政治领导力的期望差距:澳大利亚案例研究 Cuidado con la brecha, exploración de la brecha de expectativas en el liderazgo político en desastres: Un estudio de caso australiano

Risk, Hazards &Crisis in Public Policy, Volume 16, Issue 1, March 2025.
Abstract This article uses expectation gap theory to explore news coverage of the leadership performance of a national political leader in a major bushfire disaster in Australia. It does so to identify the types of behaviors and leadership that leader enacted and embodied during these events and what fire‐affected communities expected that politician ...

Global drivers of mangrove loss in protected areas

Conservation Biology, Volume 38, Issue 6, December 2024.
Abstract Despite increasing efforts and investment in mangrove conservation, mangrove cover continues to decline globally. The extent to which protected area (PA) management effectively prevents mangrove loss globally across differing management objectives and governance types is not well understood.

Tracking Small Animals in Complex Landscapes: A Comparison of Localisation Workflows for Automated Radio Telemetry Systems

Ecology and Evolution, Volume 14, Issue 10, October 2024.
Automated radio telemetry grids provide the possibility of studying movement of small animals at very fine spatial scales, but the influence of rugged terrains and vegetation on localisation error curtails the applicability of this technology. In this study, we present a comparative workflow to reduce error and show how selecting higher radio signal ...

Cattle and nurse trees shape subtropical forest–grassland ecotones

Journal of Applied Ecology, Volume 61, Issue 10, Page 2430-2443, October 2024.
Tree cover can potentially expand on the subtropical South American grasslands. Reductions in cattle densities and increases in rainfall levels associated with climate change could facilitate forest expansion in this region. Abstract South American subtropical landscapes are dominated by open grasslands and mosaics of forest–grassland formations ...

Land use history and landscape forest cover determine tropical forest recovery

Journal of Applied Ecology, Volume 61, Issue 10, Page 2365-2381, October 2024.
Both a higher land use intensity and fragmented forest landscape decreases the speed of forest recovery, indicating that human actions and landscape transformation shape the course of succession. Restoration in fragmented forest landscapes through natural regeneration is more suitable in areas with low previous land use intensity, higher forest ...

Humedad y almacenamiento de agua en el suelo en cuatro tipos de cobertura vegetal

Ciencia y Tecnología, 2022
El presente trabajo tuvo como objetivo evaluar la humedad del suelo en cuatro ambientes: bosque nativo (Cerrado nativo de Mata Atlântica), pastizal, plantación de pino y suelo con cultivo. Para análisis de humedad y contenido de agua en el suelo fue necesario colectar mensualmente 20 muestras indeformadas por cada tipo de cobertura, en cinco franjas de
