“…On the other hand, fire on grasslands affects biodiversity, ecosystem services and soil cover (Loydi, Funk, & García, 2020). After fire, only species with deep roots resprout, leaving most of the soil bare, exposed to the erosive action of rain and strong winds, which are aggravated by the rugged, steep slope of the Andean mountain range (Ribeiro et al, 2020). Likewise, soils lose much of the surface organic matter and many of the microorganisms that maintain soil life (Crespo, 2011;Oliver et al, 2017), and their function of supporting the development of the plant community (Zhao et al, 2020).…”

The tall grass vegetation in the Andean grassland ecosystems covers the largest area compared to other types of vegetation such as Puna grass, wetland and others. The grasslands are frequently set on fire by livestock farmer, seriously affecting the ecosystem. One way to mitigate this problem is to use these species as a source of plant fibre, which can be economically useful to the interests of the livestock family without affecting the ecosystem. To advance in this approach, it is necessary to know the functional characteristics of the plants; therefore, we evaluated the aerial primary productivity, plant density per m 2 , basal cover, aerial cover and leaf height, whose data were analysed using the generalised linear mixed model and the correlation between these variables with the physical-chemical characteristics of the soil, by means of principal component analysis and canonical correlation, in seven species of grassland and seven control plots, located between 3860 and 4333 metres above sea level. The results showed significant differences for p=0.001 between species, and between plots, and a canonical correlation grouped in two clusters that showed the differentiated importance of soil elements with the phytomass produced

“…The LMW PAH fraction of these mixtures accounts for ~70% of the total PAHs. These PAHs are also present in other environmental settings, such as detected in bivalve tissues from the Fjords in Canada [57] to soil sediments along rivers in the Czech Republic to China [30,58,59], to wildfires from California to Portugal [60,61], as just a few examples to further support the prevalence of these ubiquitous PAHs. This is not including those workers exposed occupationally, for which there are many, in occupations such as asphalt, coal, coke and steel industry workers [1,17,[26][27][28][29][30].…”

The Carcinogenic Properties of Overlooked yet Prevalent Polycyclic Aromatic Hydrocarbons in Human Lung Epithelial Cells

The WHO classified air pollution as a human lung carcinogen and polycyclic aromatic hydrocarbons (PAHs) are components of both indoor (e.g., tobacco smoke and cookstoves) and outdoor (e.g., wildfires and industrial and vehicle emissions) air pollution, thus a human health concern. However, few studies have evaluated the adverse effects of low molecular weight (LMW) PAHs, the most abundant PAHs in the environment. We hypothesized that LMW PAHs combined with the carcinogenic PAH benzo[a]pyrene (B[a]P) act as co-carcinogens in human lung epithelial cell lines (BEAS-2B and A549). Therefore, in this paper, we evaluate several endpoints, such as micronuclei, gap junctional intercellular communication (GJIC) activity, cell cycle analysis, anti-BPDE-DNA adduct formation, and cytotoxicity after mixed exposures of LMW PAHs with B[a]P. The individual PAH doses used for each endpoint did not elicit cytotoxicity nor cell death and were relevant to human exposures. The addition of a binary mixture of LMW PAHs (fluoranthene and 1-methylanthracene) to B[a]P treated cells resulted in significant increases in micronuclei formation, dysregulation of GJIC, and changes in cell cycle as compared to cells treated with either B[a]P or the binary mixture alone. In addition, anti-BPDE-DNA adducts were significantly increased in human lung cells treated with B[a]P combined with the binary mixture of LMW PAHs as compared to cells treated with B[a]P alone, further supporting the increased co-carcinogenic potential by LMW PAHs. Collectively, these novel studies using LMW PAHs provide evidence of adverse pulmonary effects that should warrant further investigation.

“…The effects of forest fires are known in flora [53], in fauna [54], in water [55], in the socio-economy [56], and in soil [57,58]. The use of fire as a management tool by rural communities has also been studied [59,60], being considered a negative element and penalizing these actions by the forest administrations considering it as negative for the resilience of ecosystems.…”

Different Strategies for Resilience to Wildfires: The Experience of Collective Land Ownership in Galicia (Northwest Spain)

et al. 2021

Resilience is not a particularly novel concept, but it has recently become frequently used as a measurement indicator of adaptation capacity under different approaches depending on the field of study. Ideally, for example, forest ecosystems would be resilient to wildfires, one of the most serious types of perturbation they are subjected to. In areas such as the northwest of Spain, a region with one of the most severe records of wildfire occurrence in western Europe, resilience indicators should be related with changes in land planning aimed to minimize the effects of forest fires. This article aimed to analyze the fire resilience strategies of a selected group of forest communities in northwest Spain. More specifically, the perceived risk of wildfires was compared with the actual record of fire events in these communities and the presence or absence of adaptive changes in management practices to reduce risk and improve recovery capacity. A mixed quantitative–qualitative approach was used to gather information about good practices, innovative solutions, and major obstacles for forest fire resilience in Galician common lands. The results suggest that while there is no single form of successful management, a key characteristic of resilient communities is the integration of fire as a management tool.
