Macrofungi of Mata da Margaraca (Portugal), a relic from the Tertiary Age.

ABSTRACT: Mata Nacional da Margaraça represents a rare example where the Atlantic climate influences the perpetuity of a small enclave of a previously widespread laurel forest. The higher relative humidity values (> 80%), which are almost constant all year long and the mild temperatures, rarely exceeding 30°C, even in the dry season (June to September), create an insular-like effect. The biological communities of Margaraça exhibit a transitory character. The forest is dominated by Quercus robur and Castanea sativa, yet Quercus suber, although less frequent, can also be found. The laurel species, such as Viburnum tinus, Ilex aquifolium, Laurus nobilis and the Portuguese endemic Prunus lusitanica ssp. lusitanica, relics from the ancient Portuguese Tertiary, comprise the understorey. The present work represents, to the best of our knowledge, the first regional macrofungal species list of the Mata da Margaraça published to date. The recent fires that occurred in the area have provided the opportunity to study the post-fire communities. The surveys were carried out in 2004 and later in 2018-2019. A total of 271 species were registered as belonging to Basidiomycota (? 80%) and Ascomycota (? 20%). The most represented Basidiomycota families were Russulaceae, Mycenaceae and Agaricaceae and the most represented Ascomycota families were Pyronemataceae and Pezizaceae. The new records to Portugal add up to a total of 88 species and another 116 species are new records to the province of Beira Litoral. Post-fire fungi account for 17 of the total of 271 species registered in these studies and most of these species are new to Portugal.

Project description:BackgroundDuring a LIFE research project aiming at the implementation of the conservation of the habitats and restoration of coastal wetland areas of Praia da Vitória (Terceira, Azores, Portugal), there was the opportunity undertake a systematic record of several groups of arthropods in three wetland areas: Paul da Praia da Vitória (PPV), Paul do Belo Jardim (PBJ) and Paul da Pedreira do Cabo da Praia (PPCP). The objective of the study was to perform a rapid biodiversity assessment, comparing the three sites in two different years, before and after the implementation of several conservation measures. This project also contributed to improve the knowledge of Azorean arthropod diversity at both local and regional scales, including new taxa for Terceira island and new records for Azores. Taking into consideration those aims, a set of standardised sampling methods were performed, inspired by the COBRA protocol originally developed for spiders.New informationA total of 15,810 specimens belonging to 216 arthropod species and subspecies were collected. Beetles (Insecta, Coleoptera) and spiders (Araneae) dominated, with 81 and 51 taxa, respectively. Two beetle families dominated, Staphylinidae and Curculionidae with, respectively, 22 and 17 species and subspecies. Exotic species were also dominant (132 species and subspecies), the Azorean endemics being restricted to only eight taxa. The remaining 76 species and subspecies are native non-endemic. Two rare endemic species were found with relatively sustainable populations, the Azores Cone-head Conocephalus chavesi (Orthoptera, Tettigoniidae) and the true weevil Drouetius oceanicus oceanicus (Coleoptera, Curculionidae). A total of six species are novel for the Azores, five exotic (Bledius unicornis, Carpelimus zealandicus, Oenopia doublieri, Sitona hispidulus, Trichiusa immigrata) and one possibly native (Pyrrhocoris apterus). An additional 15 taxa are novel for Terceira island, ten exotic (Cheiracanthium mildei, Cylindroiulus latestriatus, Eumodicogryllus bordigalensis, Nemobius sylvestris, Pissodes castaneus, Psyllipsocus ramburi, Trachyzelotes lyonneti, Trigonnidium cicindeloides, Tychius cuprifer, Zelotes tenuis) and five native (Aegialia arenaria, Oxypoda lurida, Platycleis sabulosa, Plinthisus brevipennis, Tachyura diabrachys).
