Most of Earth's terrestrial carbon is stored in the soil and can be released as carbon dioxide (CO2) when disturbed. Although humans are known to exacerbate soil CO2 emissions through land‐use change, we know little about the global carbon footprint of invasive species. We predict the soil area disturbed and resulting CO2 emissions from wild pigs (Sus scrofa), a pervasive human‐spread vertebrate that uproots soil. We do this using models of wild pig population density, soil damage, and their…

In this study models were used to estimate global wild boar abundance and postulated additional CO2 emissions due to wild Boar bioturbation, but the authors ignored experimental evidence about the effects ofWild boar on SOC that points in a completely different direction altogether.

Invasive wild pigs (Sus scrofa) as a human‐mediated source of soil carbon emissions: Uncertainties and future directions

A great deal of uncertainty is revealed that points to potential wide-ranging consequences of their management on CO2 emissions, including food security, loss of native plants and animals, and jeopardise cultural resources.

Environmental drivers of seasonal shifts in abundance of wild pigs (Sus scrofa) in a tropical island environment

Background Non-native wild pigs ( Sus scrofa ) threaten sensitive flora and fauna, cost billions of dollars in economic damage, and pose a significant human–wildlife conflict risk. Despite growing

Do Invasive Mammal Eradications from Islands Support Climate Change Adaptation and Mitigation?

Climate change represents a planetary emergency that is exacerbating the loss of native biodiversity. In response, efforts promoting climate change adaptation strategies that improve ecosystem

Social identity and acceptability of wild pig (Sus scrofa) control actions: A case study of Texas hunters

ABSTRACT Wild pigs (Sus scrofa) pose significant challenges to wildlife managers. This research explored Texas hunters’ acceptability of wild pig control actions, and whether acceptability varied



Soil carbon debt of 12,000 years of human land use

A machine learning-based model was fitted using a global compilation of SOC data and the History Database of the Global Environment land use data in combination with climatic, landform and lithology covariates, demonstrating that there are identifiable regions which can be targeted for SOC restoration efforts.

The role of soil carbon in natural climate solutions

Mitigating climate change requires clean energy and the removal of atmospheric carbon. Building soil carbon is an appealing way to increase carbon sinks and reduce emissions owing to the associated

The global impact of wild pigs (Sus scrofa) on terrestrial biodiversity

It is shown that wild pigs threaten 672 taxa in 54 different countries across the globe and that island endemics and taxa throughout the non-native range of wild pigs are particularly vulnerable.

Effects of biological invasions on forest carbon sequestration

There has been a rapidly developing literature on the effects of some of the major drivers of global change on carbon (C) sequestration, particularly carbon dioxide (CO2) enrichment, land use change,

Grubbing by wild boars (Sus scrofa L.) and its impact on hardwood forest soil carbon dioxide emissions in Switzerland

Wild boars considerably increased the small-scale heterogeneity of soil properties and suggest that boars will have little effect on large-scale emissions unless their numbers increase and their range expands dramatically.

Soil Carbon Sequestration Impacts on Global Climate Change and Food Security

The carbon sink capacity of the world's agricultural and degraded soils is 50 to 66% of the historic carbon loss of 42 to 78 gigatons of carbon. The rate of soil organic carbon sequestration with

Soil and human security in the 21st century

Recent advances in understanding global soil resources, including how carbon stored in soil responds to anthropogenic warming are reviewed, reveal the severity of soil-related issues at stake for the remainder of this century and the need to rapidly regain a balance to the physical and biological processes that drive and maintain soil properties.

Negative effects of cattle on soil carbon and nutrient pools reversed by megaherbivores

This field study finds that wild megaherbivores, such as elephants, increased soil carbon and nitrogen, and hence soil fertility, normally lost when only cattle are present.

Impact of wild boar (Sus scrofa) in its introduced and native range: a review

This review found that most of the published literature examines boar effects in their introduced range and little is available from the native distribution, and identified research gaps and urged the need to lower wild boar densities.
