“…The mean annual rainfall is 2000 mm and temperature ranges from a summer mean of 13.5 C to a winter mean of 2.9 C (Weather Station Villa La Angostura 2016). The soils buried by the volcanic tephra were Andisols (USDA Soil Taxonomy), and had been previously studied by Satti et al (2007) who reported the following physicochemical characteristics: 6.3 of pH, 0.08 dS/m electrical conductivity, 7.3 mg/kg extractable Olsen-P, 0.48% total N and 10.8% organic C. Regarding the 30 cm of tephra that buried these soils in 2011, they presented the following characteristics: 6.5 of pH, 0.02 dS/m electrical conductivity, 0.7 mg/kg extractable Olsen-P, 0.003% total N and 0.02% organic C. In 2013, this tephra layer had already compacted to 13 cm in the roadsides and 15 cm in the forest (Ferreiro et al 2020c).…”

“…Microbial communities release hundreds of enzymes into the environment by secretion and cell lysis, however, the ones of interest in plant litter decomposition rate are those directly involved in the degradation of lignocellulose and the cycling of nitrogen, phosphorus, and sulfur (Sinsabaugh et al 1991). Enzymes mineralyzing N (leucine‐aminopeptidase) and P (acid phosphomonoesterase), and degrading lignin (phenol oxidase) and cellulose (β‐glucosidase) have previously provided information on substrate microbial and plant rhizosphere activity in “De los Siete Lagos” tephra (Ferreiro et al 2018, 2020a).…”

Topsoil and plants had been removed for the construction of the “De los Siete Lagos” road when the June 2011 Puyehue–Cordón Caulle Complex volcanic eruption deposited 30 cm of tephra. Our objective was to study the active rehabilitation of substrate on roadsides simultaneously affected by road construction and volcanic eruption by compost addition. We studied two biological communities frequently forgotten by rehabilitation measures: invertebrates (density, richness) and microorganisms (enzymatic activities); both in the surface organic matter created by compost addition and the tephra substrate. In December 2012, we installed control, biosolids compost (BC) and municipal waste compost (MC) plots on roadside exclosures. Forest reference sites were also studied. Samplings were performed in spring 2013 and summer 2014. No surface organic matter was found in control plots, and no invertebrates were detected in the tephra layer of control plots in both samplings. BC and MC promoted the formation of a surface organic matter layer that harbored invertebrate and enzymatic activity in both sampling seasons. There were no significant differences in invertebrate density among BC, MC, and forest both in the surface organic matter and the tephra substrate. However, BC and MC invertebrate communities, dominated by springtails, did not resemble the forest community, where oribatids were the most common taxa. Statistically significant differences in total (surface organic matter + tephra substrate) microbial activities indicated a treatment order of forest > BC ≥ MC > control for enzymes related with the mineralization of nitrogen (leucine‐aminopeptidase) and phosphorus (acid phosphomonoesterase).

“…There they have affected the native flora of the subantarctic Prince Edward Island which is of relatively recent volcanic origin. R. acetosella, which is native to Europe and southwestern Asia, has spread throughout many regions of the globe and is considered very invasive in several areas (Stopps et al 2011, Ferreiro et al 2020 Invasive Species Database 2022c). L. arenarius, native to Europe, has been introduced at sites by the Great Lakes in North America.…”

Since Surtsey was formed in 1963–1967, colonisation of vascular plants has been recorded by locating the f irst colonists of each species within a 1 ha (100x100 m) quadrat grid system of the island. The abundance of individual vascular plant species was further recorded within the grid in 1996-1997, 2005-2006, and 2014-2015 using a three graded abundance scale from rare to common. During 1965–2015, a total of 74 vascular plant species were found on Surtsey. The colonisation was considerable between 1965–1979 followed by a stagnation period. After the establishment of a dense seagull colony on the southern part of the island in 1986, colonisation increased greatly and peaked between 1992–1995. The colonisation differed greatly between surface types, being highest on sandy lava and barren lava, relatively low on eolian sand and coastal sediments, and none on palagonite tuff. By classification and ordination six main vegetations types were identified over the period 1996–2015, forming a gradient from scattered, species poor pioneer vegetation to a dense, lush vegetation developed under by high nutrient input from breeding seagulls. Over this period major vegetation changes occurred. Areas with pioneer vegetation have greatly decreased, while areas with Honckenya and gravel flat vegetation, and forb rich grassland have increased. The number of species per ha increased on average from 4.8 to 7.2 and 10.4 in the years 19961997, 2005-2006, 2014-2015 respectively. Despite the great influence of seabirds within their breeding colony, most of the island still has sparse vegetation cover. The colonising species differed greatly in their rate of dispersal. Species with the greatest rate were Honckenya peploides, Poa annua and Silene uniflora, followed by Sagina procumbens, Puccinellia coarctata, Cerastium fontanum, Arabidopsis petraea, Leymus arenarius and Rumex acetosella. They are either pioneers and/or ruderals and are common on the mainland of Iceland, where they grow in sparsely covered, rocky or sandy areas or on land that has been disturbed.
