說明
In September 2012, Pico Island was surveyed along an elevational transept starting on Manhenha, at 10 m a.s.l., and ending on the Pico Mountain caldera, at 2200 m a.s.l. to obtain a systematic inventory of the bryophytes living in natural environments. A total of twelve sites were examined, separated by 200 m elevation steps. At each site, two 10 m x 10 m plots were established within 10-15 m from each other, and within each plot, three 2 m x 2 m quadrats were randomly selected and thoroughly sampled for bryophytes using microplots of 10 cm x 5 cm, collected to paper bags. Six substrates were explored within each quadrat: rock, soil, humus, organic matter, tree bark and leaves/fronds; three replicates were made for each substrate, whenever available and colonized by bryophytes, totalling a maximum of 18 microplots per quadrat, 54 microplots per plot, 108 microplots per site and 1296 microplots on the 12 sites of Pico Island. It was possible to collect two thirds of the maximum expected number of microplots (N=878; 67,75%), resulting in 4896 specimens, the great majority of which (n=4869) were identified to the species/subspecies level. Overall, it was possible to identify 70 moss’ and 71 liverwort’ species. The elevation levels both with a greater number of microplots and higher richness of species were those between 600-1000 m a.s.l., coinciding with the native forest plots. The study contributed to improve the knowledge of Azorean bryophyte diversity and distribution at both local and regional scales, including the recording of new taxa for Pico Island and the Azores.

計畫資料
The MOVECLIM - AZORES project aimed to improve the knowledge of the bryophyte flora of the archipelago of Azores (Portugal) in a systematic way. Pico Island was the first island to be surveyed since it includes some of the best preserved natural areas of the Azores and granted the largest elevational transect, from 10 m to 2200 m a.s.l., granting the opportunity to survey 12 natural vegetation sites. The collections were made during the first week of September 2012, using BRYOLAT Protocol, adapted to the Azores' conditions and knowledge of vascular species. This paper lists the taxonomic records and provides information on each species’ ecology and substrate.

| 研究區域描述 | The Azores archipelago, located in the North Atlantic Ocean, is divided into three groups of islands, the Eastern group (Santa Maria and São Miguel Islands), the Central group (Terceira, Graciosa, São Jorge, Pico, and Faial Islands), and the Western group (Flores and Corvo Islands. The climate is temperate oceanic, with regular and abundant rainfall, high levels of relative humidity, and persistent western winds, mainly during the winter and autumn seasons. Pico Island, the third largest (area: 445 km2) and the highest point of Portugal (maximum elevation: Piquinho, at 2,350 m a.s.l.), lying roughly at 38°28′12′′N | 28°23′42′′W. The island is known for some very important pristine areas at middle-high and high elevations, most of which are included in the Pico Natural Park. Notwithstanding, vast areas, especially from 200 m to 400 m a.s.l., are heavily altered due to urbanization and agriculture. Vegetation varied along the elevation transect, including all the eight zonal vegetation types found in the Azores (Elias et al., 2016): Erica-Morella coastal woodlands (10 m a.s.l.), Picconia-Morella lowland forests (200 m a.s.l.), Laurus submontane forests (400-600 m a.s.l.), Juniperus-Ilex montane forests (800 m a.s.l.), Juniperus montane woodlands (1000 m a.s.l.), Calluna-Juniperus altimontane scrublands (1200-1400 m a.s.l.), Calluna-Erica subalpine scrubland (1600-1800 m a.s.l.) and Calluna alpine scrubland (2000-2200 m a.s.l.). |
| 研究設計描述 | The field study followed the BRYOLAT methodology (Ah-Peng et al., 2012), but incorporated some modifications according to the conditions and knowledge of the Azores flora (Gabriel et al., 2014; Borges et al., 2018). The sampling involved 12 sites, located at 200 m elevation intervals, ranging from 10 meters to 2200 meters. At each site, two plots of 10 m by 10 m were placed within a homogeneous ecosystem, 10 to 15 m apart from each other. Three quadrats measuring 2 meters by 2 meters were randomly surveyed from each plot. Three replicates (microplots) measuring 5 centimeters by 10 centimeters each, were collected from six different substrates: rock, soil, humus, organic matter, bark, and leaves/fronds, whenever available. Back in the laboratory, taxa were identified to the species/subspecies level, whenever possible, and the cover-abundance and sociability of each specimen bryophyte species from each microplot. |

The inventory was conducted during September 2012 under the responsibility of Rosalina Gabriel and Claudine Ah-Peng, with the participation of Márcia Catarina Mendes Coelho, Silvia Calvo Aranda, Débora S. G. Henriques and Fernando Pereira. Paulo A.V. Borges generally helped in the field. Bryophytes were sampled along the elevation gradient using a modified BRYOLAT standardised method in order to include taxonomic information of 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 thus divided into 25 quadrats (2 m x 2 m), from which three were randomly selected to further inspection. Each quadrat was carefully examined to collect three microplots of 50 cm2 (10 cm x 5 cm) for each of the substrates that were colonized by bryophytes: rock, soil, humus, organic matter, tree bark and leaves/fronds. The three microplots from bark were sampled in stratified way along the height of the tree, 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).
| 研究範圍 | This study covers 12 sites, each including two plots of 100 m2 each, placed along an elevation gradient, with a 200 m elevation step, from 10 m to 2200 m a.s.l. in Pico Island (Azores, Portugal). The transect starts in Manhenha, at 10 m a.s.l., and ends at the large Caldeira of Pico Mountain, at 2200 m. a.s.l., roughly following an East-West direction. |

| 品質控管 | FIELD: Plots were placed within homogeneous areas of the most representative native vegetation found at each sampled elevation. A visit made by PAVB and RG in July 2012 prospected the best sampling sites. Sampling was made by experienced bryologists, who ensured the samples were properly collected, while avoiding the excessive removal of material. STORAGE: After the collection of 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 on the Herbarium of the University of the Azores (AZU), Section Bryophytes, under the name “MOVECLIM – AZORES project: Bryophytes from Pico Island (2012)”. TAXONOMY: All efforts were made to achieve an 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), whereas liverworts were identified using the floras written by 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 BBS Field Guide online pages, the Bildatlas der Moose Deutschlands for morphological and ecological data. Nomenclature follows Gabriel et al. (2010) and adaptations available on the Azorean Biodiversity Portal (2023). Species identification was performed by Márcia Catarina Mendes Coelho, under the supervision of Rosalina Gabriel, and by Helena Hespanhol. In 2023, all the Frullania specimens were reviewed by Leila Nunes Morgado under the supervision of Rosalina Gabriel. The identification of some challenging specimens was performed by Manuela Sim-Sim and Cecília Sérgio. REPRESENTATIVENESS OF THE PICO BRYOFLORA: Species accumulation curves were generated based on a presence–absence microplot-scale matrix using Chao 2 estimator. Sampling completeness was high both for liverworts (87.5%) and mosses (94.5%) (Coelho et al., 2021). |
方法步驟描述:
- Firstly, field and laboratory work were completed in order to have herbarium records fully identified (Coelho et al., 2021): 1. Conceptualize an adequate research design to improve the knowledge of the bryoflora of native habitats in Pico Island (Azores, Portugal); 2. Select 12 sites along an elevational transect in Pico 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 Pico 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 878 records, corresponding to each microplot of 10 cm x 5 cm; 2. Prepare one data table extension (occurrence), with 4896 records, corresponding to the inventory of all bryophytes found in the microplots.
