From 25 to 28 September 2012, an inventory of the bryoflora was carried out on Terceira Island (Azores) along an elevational transect, starting at the Serreta (38.76658 Latitude; -27.37539 Longitude; 40 m a.s.l), and culminating on Santa Bárbara (38.73064 Latitude; -27.32164 Longitude; 1000 m a.s.l). The primary objective was to systematically inventory the bryophytes inhabiting the preserved areas of native vegetation environments. Six sites were selected, each spaced at 200 m elevation intervals. Within each site, two 10 m x 10 m plots were established in close proximity (10-15 m). Within these plots, three 2 m x 2 m quadrats were randomly selected and sampled for bryophytes using microplots measuring 10 cm x 5 cm, which were then collected into paper bags. Six substrates were surveyed in each quadrat (rock, soil, humus, organic matter, tree bark, and leaves/fronds). Three replicates were obtained from all substrates available and colonised by bryophytes, resulting in a total of 636 records (eventID) of a maximum of 824 (3 replicates * 3 quadrats * 2 plots * 6 elevations). The events yielded a grand total of 3677 specimens (occurrenceID), with 38 families, 60 genera, 92 identified species and subspecies, including 34 mosses (Phylum Bryophyta) and 58 liverworts (Phylum Marchantiophyta). Of these 92 taxa, two were Azorean endemic species, five were Macaronesian endemic species, 11 were European endemic species, and 74 were native, non-endemic species. The altitudes with the highest species richness, and highest number of endemic species, spanned between 600-1000 m a.s.l above sea level, coinciding with the most preserved forests at the highest altitudes. This study contributed to expanding knowledge about the diversity and distribution of the Azorean Bryoflora, both on a local and regional scale.Sampling Description
Study Extent
This study covers six sites, each including two plots of 100 m2 each, placed along an elevation gradient, with a 200 m elevation step, from 40 m to 1000 m a.s.l., within the limits of the Terceira Natural Park (Terceira Island, Azores, Portugal). The transect starts in Serreta (Lighthouse), at 40 m a.s.l., and ends at Santa Bárbara Mountain, at 1000 m. a.s.l., along the western side of the Island.Sampling
The inventory was conducted in September 2012, under the responsibility of Rosalina Gabriel, with the participation of Débora S.G. Henriques, Márcia C.M. Coelho, Raquel Hernández-Hernández and Fernando Pereira. Bryophytes were sampled along the elevation gradient using a modified BRYOLAT standardised method in order to include taxonomic information on phorophytes and environmental data (Ah-Peng et al., 2012; Gabriel et al., 2014; Borges et al., 2018). At each site, two plots of 10 m x 10 m were set 10-15 m apart. Each plot was divided into 25 quadrats (2 m x 2 m), from which three were randomly selected for further inspection. Each quadrat was carefully examined to collect three microplots of 50 cm2 (10 cm x 5 cm) for the substrates colonized by bryophytes: rock, soil, humus, organic matter, tree bark, and leaves/fronds. The microplots collected from tree bark were sampled in a stratified way, at the lowest (1-50 cm), medium (51-100 cm), and higher (101-200 cm) spots. Environmental data for each microplot was obtained in ordinal scales for Light, Evaporation, Humidity, and Rugosity, using the scales proposed by Gabriel & Bates (2005).Quality Control
FIELD: Plots were placed within homogeneous areas of the most representative native vegetation found at each sampled elevation. Sampling was made by experienced bryologists, who ensured the samples were properly collected, while avoiding the excessive removal of material. STORAGE: After collecting the microplots for paper bags, these were left open and separated in a darkened room until complete dehydration. After identification, every sample was transferred to herbarium envelopes properly identified. All these envelopes were stored in the Herbarium of the University of the Azores (AZU), Section Bryophytes, under the name “MOVECLIM – AZORES project: Bryophytes from Terceira Island (2012)”. TAXONOMY: All efforts were made to achieve accurate identification of the specimens: (i) the most updated keys and floras were used by/under the supervision of experienced bryologists; (ii) challenging samples were sent to specialists for confirmation/identification; (iii) identification of extremely small or etiolated specimens was not pursued to the species level. Mosses were identified using the floras of Smith (2004) and Casas et al. (2006); liverworts were identified using the floras of Paton (1999) and Casas et al. (2009) and the taxonomic key of Schumacker and Váňa (2005). Visual guides (e.g. Atherton et al. 2010; Lüth, 2019) were also consulted, as well as the online pages of the British Bryological Society and the Bildatlas der Moose Deutschlands. Nomenclature follows Gabriel et al. (2010) and adaptations available on the Azorean Biodiversity Portal (2024). Species identification was mainly performed by Débora S.G. Henriques and Rosalina Gabriel. In 2023-2024, all the Frullania specimens were reviewed by Leila Nunes Morgado under the supervision of Rosalina Gabriel.Method steps
- Initially, field and laboratory work were completed in order to have herbarium records fully identified (Henriques et al., 2017): 1. Conceptualize an adequate research design to improve the knowledge of the bryoflora of native habitats in Terceira Island (Azores, Portugal); 2. Select six sites along an elevational transect in Terceira Island, using areas with the highest cover of native vascular plant species; 3. Select two study plots (10 m x 10 m) per site, separated by 10-15 m within a homogeneous vegetation area; 4. In each plot, randomly select three quadrats (2 m x 2 m) for further inspection; 5. In each selected quadrat, examine all available substrates, including rock, soil, humus, organic matter, bark, and leaves/fronds. Collect three samples, replicates or microplots (10 cm x 5 cm) from each substrate; 6. Dry the material in an airy and darkened room; 7. Identify the species present in each microplot; 8. Store samples in the Herbarium of the University of the Azores – Section Bryophytes (AZU-B). Secondly, data files were prepared to share information regarding Terceira Island bryophytes with GBIF and other platforms, using Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. 1. Prepare a core data table (events), containing the 636 records, corresponding to each microplot of 10 cm x 5 cm; 2. Prepare one data table extension (occurrence), with 3686 records, corresponding to the inventory of all bryophytes found in the microplots.
