“…Afterwards, when the availability of nutrients in rock mass matrix is improved, conditions are created for the growth and development of higher plants such as herbs, and these higher plants further decompose and break minerals and further change the properties of minerals by root adhesion, interlotting and peeling (Fukami and Nakajima, 2013;Tamura et al, 2017;Tian et al, 2019). The decomposition and stock of organic matter and the synthesis of humus during the growth and diffusion of higher plants could also promote the stocks of organic matter and nutrients (Castellano et al, 2015;Kjaer et al, 2018;Vilmundardóttir et al, 2018). This process is actually an evolution of the "food chain".…”

The accumulation of soil organic matter and nutrients is an important pathway in effectively understanding the mechanisms of plant settlement and rock weathering, while the characteristics of soil organic carbon (C), nitrogen (N) and phosphorus (P) under different vegetation remain unclear. In this study, the stocks and stoichiometry of soil organic C, N and P were determined in different positions and types of vegetation on the surface of the Leshan Giant Buddha. We found that the total stocks of soil organic C, N and P were 1689.77, 134.6 and 29.48 kg, respectively, for the Buddha. The stocks of soil organic C, N and P under vascular plants were higher than those under other vegetation, with highest values observed under herb. Higher stocks per unit area (m 2 ) of soil organic C, N and P were found on the left and right arms, shoulders, and two platforms. These results provide a full primary picture in understanding soil organic C, N and P accumulation and distribution on the surface of the Buddha, which could supply the fundamental data on weathering management of the Buddha and other similar open-air stone carvings.

“…Global modelling suggests a considerable hydrological influence of bryophytes (and lichens) on rainfall interception (Porada et al 2018), and soil hydraulic conductivity (Voortman et al 2014) but also highlights the absence of empirical data for much of the globe. These impacts of bryophytes are fundamental to primary succession in many modern contexts (Mueller-Dombois & boehmer 2013, Arróniz-Crespo et al 2014, Vilmundardóttir et al 2018. because of their deep geological history, early terrestrial environments are also likely to have been shaped by bryophytes (Lenton et al 2016).…”

Since the late Cambrian era, bryophytes have been shaping terrestrial ecosystems through unique and diverse suites of anatomical, physiological, and morphological traits. In this review we highlight historical and recent work in bryophyte functional ecology, with an emphasis on knowledge gaps and opportunities for future work. While we cannot always avoid the temptation to contrast with tracheophyte (especially angiosperm) studies, our aim is to de-center that perspective in favor of a more universal understanding of functional land plant ecology. We therefore center our description on three core aspects of bryophytes that are poorly represented in tracheophyte studies: (I) dynamic water content (including poikilohydry and desiccation tolerance), (II) multiple scales of interaction with environment, and (III) reproduction and life history. We also highlight the diverse and wide-ranging influence bryophytes have on ecosystem processes, including primary productivity, nutrient cycling, hydrology, and ecological interactions with other species. Furthermore, while the study of bryophyte functional traits has rapidly grown in the past decade, important gaps in phylogenetic and geographic coverage persist and constrain the development of a more universal land plant functional ecology theory.

“…In Hekla eruptions during the 20th century the lava flow volumes make up between 80-100% of the entire erupted volume (Pedersen et al, 2018) indicating that lava yield is very important for assessing the productivity of the Hekla volcano. However, there are few studies focused on the effusive history of Hekla, and few attempts have been made to provide a detailed map of the historical activity (Kjartansson, 1945;Thorarinsson, 1967;Jakobsson, 1979a;Montalvo, 2013;Kaldal et al, 2018).…”

Historical lava flow fields at Hekla volcano, South Iceland

Hekla volcano is known to have erupted at least 23 times in historical time (last 1100 years); often producing mixed eruptions of tephra and lava. The lava flow volumes from the 20th century have amounted 80\% to almost 100\% of the entire erupted volume. Therefore, evaluating the extent and volume of individual lava flows is very important when assessing the historical productivity of Hekla volcano. Here we present new maps of the historical lava flow fields at Hekla in a digital format. The maps were produced at a scale of 1:2000–10000 using a catalogue of orthophotos since 1945, acquired before and after each of the last five eruptions, combined with field observation of stratigraphy, soil profiles, tephra layers and vegetation cover. The new lava flow maps significantly improve the historical eruptive history of Hekla, prior to the 1947 eruption. The historical lava flow fields from Hekla cover ∼233 km² and the lavas reach up to 16 km from Hekla volcano. Flow lengths up to 20 km are known, though lava flows only travelled up to 8–9 km from Hekla in the last 250 years. Identified historical vents are distributed between 0 and 16 km from Hekla volcano and vents are known to have migrated up to 5 km away from Hekla during eruptions. We have remapped the lava flow fields around Hekla and assigned the identified flow fields to 16 eruptions. In addition, ca. 60 unidentified lava units, which may be of historical age, have been mapped. It is expected that some of these units are from known historical Hekla eruptions such as the 1222, 1341, 1510, 1597, 1636 and potentially even from the previously excluded eruptions such as 1436/1439.
