Holocene sea‐level and environmental changes on the Isle of Mull, Scotland

Journal of Quaternary Science, EarlyView.
ABSTRACT Sea‐level and coastal changes are reconstructed on the Isle of Mull, western Scotland, from 10 988 to 10 507 cal BP to the present. This research has produced the first SLIP for the Isle of Mull. A multiproxy approach including pollen, spore, foraminifera and diatom analyses reveals palaeoenvironmental changes from two coastal sites.

Failure in Motion: A Framework for Capability Erosion and Institutional Dysfunction

Strategic Change, EarlyView.
ABSTRACT Drawing on the literature on capability erosion and institutional dysfunction (ID), this study develops a conceptual framework that sheds new light on how the interaction between capability erosion and ID creates conditions for business failure across borders. By articulating two dimensions of heterogeneous capability and resource erosion (i.e.

Accelerating decline of wildfires in China in the 21st century

Frontiers in Forests and Global Change
Global wildfires have increased in frequency and intensity, especially in temperate regions, in the context of global warming. However, the spatiotemporal characteristics of wildfire frequency and intensity are still not well understood.

Air Quality Deterioration of Urban Areas Caused by Wildfires in a Natural Reservoir Forest of Mexico

Advances in Meteorology, 2015
Many regions of the world suffer loss of vegetation and reduced air quality due to wildfires. Studies on aerosol emissions by wildfires often discuss the negative effects of atmospheric contaminants from a regional or mesoscale perspective.

Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates

Land Degradation &Development, EarlyView.
ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...

Wildfires' Cost for Societal Welfare: Economic Evaluation of Forestry Ecosystem Services Losses in Southern Italy

Land Degradation &Development, EarlyView.
ABSTRACT Forest ecosystem services (ESs) are garnering increasing public attention as awareness grows regarding society's fundamental dependence on them for well‐being. Forest fires, one of the major disturbances of ESs, are becoming more frequent and destructive, exacerbated in part by climate change.

Human Mediation of Wildfires and Its Representation in Terrestrial Ecosystem Models

Fire
Increasing wildfires are causing global concerns about ecosystem functioning and services. Although some wildfires are caused by natural ignitions, it is also important to understand how human ignitions and human-related factors can contribute to ...

Spatiotemporal Fire Patterns and Post‐fire Forest Change in Peru (2000–2021)

Land Degradation &Development, EarlyView.
ABSTRACT Fire is increasingly more frequent and severe in many tropical regions, leading to significant forest loss, diminished biodiversity, and reduced Nature's contributions to people (NCPs). In this study, we analyzed the spatiotemporal patterns of fire in Peru and its regions, focusing on: (1) burned area, (2) size, and (3) number of fires, using ...

Data‐Based Detection of Antagonistic Agents in a Robot Swarm Solving a Dynamic Coverage Task

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Robot swarms can be deployed as moving surveillance systems, for instance, as mobile anti‐poaching systems for monitoring wildlife and detecting poaching activities. Since poachers have an interest in evading detection, robots are at risk of being hijacked and manipulated to behave antagonistically, for example, to prevent the correct ...
