This study explores the composition and structure of species communities associated with the native Azorean tree species Laurus azorica (Seub) Franco (Magnoliophyta, Magnoliopsida, Laurales, Lauraceae). Communities were sampled in six Islands covering the occidental (Flores), central (Faial, Pico, Terceira) and eastern (São Miguel, Santa Maria) groups of Azores Archipelago during the BALA project, using standardised sampling protocols for surveying canopy arthropod fauna. In addition, the study characterises the distribution of species regarding their colonisation status and feeding modes and, finally, compares communities of different Islands. Ninety-four arthropod species totalling 10,313 specimens were collected on L. azorica. The Arthropod community was dominated by Hemiptera species, most of them being herbivores. Endemic and native species showed a very high abundance representing about 94% of the total species abundance. However, despite introduced species being represented by few individuals (6% of the total abundance), their diversity was remarkable (28 species and no significant difference with diversity found in endemic and native species communities). Analysis of rarity patterns revealed a stable community of endemic species (alpha gambin SAD model approaching a log-normal shape), intermediate stable community of native species (alpha SAD gambin model approaching a poisson log-normal) and a less stable community of introduced species (alpha SAD gambin model approaching a log-series shape). A dissimilarity analysis revealed high similarity between communities of Terceira and Pico and high dissimilarity between Flores and Faial communities. We observed a clear individualisation of the different islands when considering endemic species, whereas we observed high overlap when considering native and introduced species groups. Canopy community distribution confirms the results obtained in a previous study which suggest the stability of native and endemic arthropods species communities over introduced species community in native forests fragments. Arthropod species were richer than bryophytes, lichens and vascular plants species. We found that L. azorica serve as the substrate for very few vascular plants species (four epiphytes species), which were present in all Islands, except Elaphoglossum semicylindricum, which does not occur in Santa Maria. L. azorica shelters a significant number of bryophytes and lichens species. Thirty-two lichens and 92 bryophyte species, including 57 liverworts and 35 mosses, are referred to this phorophyte. Five bryophyte species, all Azorean endemics, are considered Endangered by IUCN Criteria. L. azorica harbours a poor community of epiphyte vascular plant species and all of them were ferns, but the community of bryophytes and lichens are not negligible although very low compared to the community found on other previously studied Azorean trees, the Azorean cedar Juniperus brevifolia. The present study shows that most islands present particular species distribution patterns without geographical correlation and that conservation programmes should be adapted to each Island. The study, therefore, calls for a specialisation of conservation programmes for each of the Islands.

Halophytic Clonal Plant Species: Important Functional Aspects for Existence in Heterogeneous Saline Habitats

Plant modularity-related traits are important ecological determinants of vegetation composition, dynamics, and resilience. While simple changes in plant biomass resulting from salt treatments are usually considered a sufficient indicator for resistance vs. susceptibility to salinity, plants with a clonal growth pattern show complex responses to changes in environmental conditions. Due to physiological integration, clonal plants often have adaptive advantages in highly heterogeneous or disturbed habitats. Although halophytes native to various heterogeneous habitats have been extensively studied, no special attention has been paid to the peculiarities of salt tolerance mechanisms of clonal halophytes. Therefore, the aim of the present review is to identify probable and possible halophytic plant species belonging to different types of clonal growth and to analyze available scientific information on responses to salinity in these species. Examples, including halophytes with different types of clonal growth, will be analyzed, such as based on differences in the degree of physiological integration, ramet persistence, rate of clonal expansion, salinity-induced clonality, etc.

“…Elias et al 2016). However, apart from some native shrubs of Morella faya , still found in PPV and PPCP, the main native species found in the area include species typical of humid zones, namely Juncus ( J. acutus , J. maritimus , J. effusus ) and Ruppia maritima (Elias et al 2019). Presently, most of the area is covered with exotic and invasive species, with the giant cane ( Arundo donax ), being especially abundant in PBJ, and the sticky snakeroot ( Ageratina adenophora ) in PPCP.…”

“…The three coastal wetlands of Praia da Vitória municipality are a case in point, well worth restoration and habitat protection. The areas, studied during the LIFE-CWR Project – Paul da Praia da Vitória (PPV), Paul do Belo Jardim (PBJ) and Paul da Pedreira do Cabo da Praia (PPCP) – are best known for their birds (Barcelos et al 2015; Dias 2018; Goulart et al 2019); however, they harbour other important and interesting biological groups, such as molluscs and arthropods (Martins and Borges 2019), plants and lichens (Elias et al 2019).…”

During the LIFE-CWR project "Ecological Restoration and Conservation of Praia da Vitória Coastal Wet Green Infrastructures", there was the opportunity to undertake a systematic record of bryophytes at Paul da Praia da Vitória (PPV), Paul do Belo Jardim (PBJ) and Paul da Pedreira do Cabo da Praia (PPCP), three coastal wetland areas of Praia da Vitória (Terceira, Azores, Portugal). The objective of the study was to perform a biodiversity assessment, comparing the three sites at two different moments, before and after the implementation of several conservation measures. This project also contributed to improve the knowledge of Azorean bryophyte diversity at both local and regional scales, including the recording of two new taxa for the Azores and three new taxa for Terceira Island. This paper reports the results of the first extensive survey of bryophyes of the three coastal wetland areas of Praia da Vitória (Terceira Island, Azores, Portugal). The identification of a total of 504 samples, 240 collected in 2013 and 2016 (before the LIFE-CWR intervention) and 265 in 2017 and 2018 (after the intervention), resulted in a list of 58 species of bryophytes (one hornwort, eight liverworts and 48 mosses). These include two new records for the Azores (Bryumklinggraeffii, Ptychostomumbornholmense), three new records for Terceira Island (Bryumtenuisetum, Dicranellahowei, Trichostomumcrispulum) and at least 15 new records for the municipality of Praia da Vitória (e.g., Cephaloziellahampeana). Some species that had not been recorded on the island since 1937 (e.g., Fissidenscrispus) were collected during this study, as well as a Macaronesian endemic liverwort (Radulawichurae), an Iberian-Macaronesian liverwort (Frullaniaazorica) and a moss species with European distribution (Ptychomitriumnigrescens). From the recorded species, only one moss (Leptophascumleptophyllum), of subtropical origin, is considered invasive in Europe.
