Effective monitoring and combatting the effect of non-indigenous seaweeds relies on a solid confirmation of the non-indigenous status of the species. We critically analysed the status of presumed non-indigenous seaweed species reported from the Mediterranean Sea, the Northeast Atlantic Ocean and Macaronesia, resulting in a list of 140 species whose non-indigenous nature is undisputed. For an additional 87 species it is unclear if they are native or non-indigenous (cryptogenic species) or their identity requires confirmation (data deficient species). We discuss the factors underlying both taxonomic and biogeographic uncertainties and outline recommendations to reduce uncertainty about the non-indigenous status of seaweeds. Our dataset consisted of over 19,000 distribution records, half of which can be attributed to only five species (Sargassum muticum,Bonnemaisonia hamifera,Asparagopsis armata,Caulerpa cylindraceaandColpomenia peregrina), while 56 species (40%) are recorded no more t...

This paper seeks to identify the pedagogical resources used by kindergarten, primary and secondary teachers in Azores Islands. Additionally, an investigation will be made into how these resources are mobilized in teachers’ pedagogical practice, with the aim of understanding to what extent digital resources, particularly learning objects, are present in schools. For this purpose, a study was developed, which included a questionnaire survey conducted online, and sent to teachers in 2021/22. A total of 426 answers allowed us to conclude that the use of pedagogical resources is still far from the current and emerging need to mobilize digital resources, particularly learning objects, as a tool to enhance meaningful learning.

The macroalgal flora of Graciosa (central group of Azores archipelago) is poorly known, with only 116 species recorded so far (authors personal data). The published information reflects occasional collections from sporadic field visits to the Island. To overcome this, a thorough investigation under the Expedition “GRACIOSA/2004”, the Campaigns “PADEL/2006”, “MACROBIOLMOL/2014” and “PIMA-BALA/2017” involving sample collecting and presence data recording, was undertaken over an area of 19 km2 encompassing littoral and sublittoral levels down to about 40 m around the Island. This paper lists the taxonomic records and provides information on species ecology and occurrence around the Island improving the knowledge of the Azorean macroalgal flora at both local and regional scales. A total of 1692 specimens belonging to 250 taxa of macroalgae (and including 55 taxa identified only at the genus level) are registered, comprising 166 Rhodophyta, 36 Chlorophyta and 48 Ochrophyta (Phaeophyceae)...

In this study we investigated <i>Ralfsia</i>-like crusts (i.e. excluding <i>Ralfsia</i> sensu stricto, <i>Stragularia</i> spp. and/or Scytosiphonaceae crustose phases) with an emphasis on the North Atlantic Ocean using molecular data (COI-5P, ITS and <i>rbc</i>L-3P) combined with morpho-anatomical comparisons of type material and contemporary specimens. Of the four species of <i>Ralfsia</i> previously reported in Europe, only <i>R. fungiformis</i> is presently recognized as belonging to <i>Ralfsia</i> sensu stricto, Ralfsiaceae, with the remaining species, <i>R. lucida, R. ovata</i> and <i>R. verrucosa</i>, of uncertain taxonomic status. Our study revealed 11 independent genetic lineages of <i>Ralfsia</i>-like taxa, which were not assignable to any of the recognized families of the Ralfsiales. To accommodate this diversity, we propose Pseudoralfsiaceae Parente, Fle...

Copyright © 2001 Academia Canaria de las Ciencias.Se relacionan las macroalgas (173 táxones) identificadas hasta el momento, como resultado de las recolecciones realizadas durante la expeditión científica MACARONESIA 2000 en el intermareal y submareal de las Ilhas Selvagens (mayo de 1999). Se citan por vez primera para estas costas 66 táxones, de ellos 53 corresponden a especies y 13 géneros. Desde el punto de vista ficogeográfico se amplía el rango de distribución de numeorsas especies. Las nuevas citas contribuyen principalmente a incrementar el número de táxones con patrones de distribución macaronésica y anfiatlántica. En este sentido, se confirma lo expuesto por Prud'homme van Reine & van den Hoek (1990) para sustentar y considerar la flora marina bentónica de los archipiélagos de Salvages, Madeira y Canarias, con características similares, desinándolos por ello como un grupo de archipiélagos que conforman la Macaronesia s.s.ABSTRACT: A total of 173 taxa of seaweeds have been identified from the Selvagens Isles as result of a recent Research Expedition (MACARONESIA 2000, May 1999), with samples from intertidal and subtidal habitats. 66 taxa (53 species + 13 génera) are new records for lhe islands. Ficogeographically, the results presented here increase the number of al11phiatlantic species anel confirmed several others species with restricted distribution in the Macaronesia s.s. archipelagos (Madeira, Selvagens and Canaries) as defined by Prud' homme van Reine & van den Hoek (1990)

ABSTRACT Trends in abundance, temporal occurrence and spatial distribution of marine and brackish non-indigenous species (NIS) are part of the indicators to assess the compliance of Good Environmental Status in the European Marine Strategy Framework Directive (EU-MSFD). European-wide regional and national databases for NIS will be useful for the implementation of the EU-MSFD but there are still spatial gaps for some regions and taxonomic groups. In 2009, Portugal was among the countries with the lowest reported numbers of NIS in Europe and a national online database on NIS was not available. This study provides an updated list of NIS registered in Portuguese coastal and estuarine waters, including mainland Portugal and the Azores and Madeira archipelagos. A list of 133 NIS was cataloged, most of which recorded in the last three decades, showing that this area of the North Atlantic is no less prone to introductions than neighboring areas. Most NIS reported in the current inventory are native in the Indo-Pacific region. Fouling and ballast water are the most likely introduction vectors of NIS in the studied area but shipping routes connecting to the NIS native regions are rare, indicating that most species are secondary introductions. The high number of NIS in the Azores and Madeira islands indicates that this ecosystem type seems to be more susceptible to invasions but these preliminary results might be biased by a higher number of studies and knowledge on the NIS occurrence on the islands.
