Introduction
My research focus on the Phylogeny of Red Algae, especially of those involving alternation of generation between gelatinous and crustose phases. I am also interested in studying morphological and developmental features that help distinguishing the members of species-complexes. Other areas of interest are biodiversity and ecological monitoring.

Article
Scenarios constitute narratives or storylines that reasonably describe how the future is likely to unfold. The usefulness of scenarios in Maritime Spatial Planning (MSP) is now recognised within policy and research, with many institutions urging the development of likely trajectories in the future state of the marine environment and space. However,...

This paper explores how geography shapes human uses of the maritime space along the Atlantic archipelagic territories of Macaronesia, a biogeographical region that includes the archipelagos of the Azores, Madeira, Selvagens, Canary Islands and Cape Verde. The way specific geographic characteristics of these islands influence and even determine mari...
Article
The gelatinous, calciferous red alga Renouxia antillana was described in 1995 based on material from Guadeloupe, French West Indies, and accommodated in a new family and order (Rhodogorgonaceae, Rhodogorgonales) along with the genus Rhodogorgon from Belize and Caribbean Panama. For more than 20 years, Renouxia has remained monotypic, with rare repo...

This paper reports a recently discovered population of Caulerpa prolifera in the Azores (NE Atlantic), which becomes the westernmost record of this species in European waters. Morphological, anatomical and molecular characters were investigated for species recognition. The occurrence of the species in the Azores represents a northern expansion of i...

An updated list of the names of the marine macroalgae of Cabo Verde, an archipelago of ten volcanic islands in the central Atlantic Ocean, is presented based on existing reports, and includes the addition of 36 species. The checklist comprises a total of 372 species names, of which 68 are brown algae (Ochrophyta), 238 are red algae (Rhodophyta) and...
Article
Acrothamnion preissii is an invasive species in the Mediterranean Sea, and is listed among the 100 worst non-indigenous species. In July and August 2009, this non-native red macroalga was found for the first time in the Azores (on Santa Maria), and this represents the first record of this species in the Atlantic. Here, we describe the establishment...

The tropical alga previously recognized as Gibsmithia hawaiiensis (Dumontiaceae, Rhodophyta) was recently suggested to represent a complex of species distributed throughout the Indo-Pacific Ocean and characterized by a peculiar combination of hairy (pilose) gelatinous lobes growing on cartilaginous stalks. Phylogenetic reconstructions based on thre...

Gibsmithia hawaiiensis is a peculiar red alga characterized by furry gelatinous lobes arising from a cartilaginous stalk. The species has been recorded from tropical reef systems throughout the Indo-Pacific. A multilocus phylogeny (UPA, rbcL, COI-5P) of 36 specimens collected throughout the species distribution range, showed high genetic diversity...

The crustose red algal genus Peyssonnelia (Peyssonneliales, Rhodophyta) in the Azores: from five to one species. Arquipelago. Life and Marine Sciences 32: 1-9. The family Peyssonneliaceae comprises a worldwide group of non-calcified to calcified, crust-forming red algae of great ecological significance. Of the genera currently recognized in the fam...

Due to their sedentary characteristic and the sensibility of certain taxa to excessive nutrients or toxic substances, the benthic macroalgal assemblage of a given locality reflects the effects of long-term exposure to pollution. For this reason, seaweeds have been used to assess the environmental condition of coastal communities. Since the Water Fr...

In the northwestern Gulf of Mexico, beds of rhodoliths and unconsolidated rubble at 55-70 m depth are associated with unique offshore deep bank habitats known as salt domes or diapirs. Prior to the 2010 BP Deepwater Horizon oil spill these harbored the highest known seaweed diversity in the northern Gulf of Mexico. Six post-spill cruises led offsho...

The generic concepts of the crustose family Peyssonneliaceae will be critically assessed in a revised worldwide phylogeny of the family on the basis of phylogenetic analysis of chloroplast-encoded rbcL and tufA, chloroplast 23S UPA and mitochondrial cox1 sequences derived from 336 samples worldwide representing 172 species and twelve genera. Type o...

Molecular characterization (plastid-encoded tufA gene) of New Caledonian members of the Caulerpa racemosa–Caulerpa peltata complex identified five lineages, each possibly harboring multiple species-level entities. On a global scale, the complex encompassed six lineages, two of which were pantropical and the remainder seemingly were restricted to th...

Comparative rbeL. sequence analysis indicates that the species going under the name Schizymenia dubyi in the Azores should be referred to as S. apoda. Sequences of Sehizymenia specimens from China and Namibia were also identified as S. epode, of which the type locality is the Cape Province in South Africa. Sehizymenia dubyi, described from Atlantic...

Gelidium J.V. Lamouroux is an economically and ecologically important red algal genus including about 118 species worldwide. A total of 17 species are reported in Korea. We collected G. crinale, G. divaricatum, G. elegans, G. vagum, an unidentified species and studied phylogenetic relationships of the species using rbcL, psaA, and cox1 genes. Topol...

Punctaria tenuissima (Chordariaceae, Phaeophyceae) is reported for the first time from the Azores. Erect thalli were collected on the Island of Sao Miguel; they were up to 3 cm long, flattened and often twisted. The plurilocular sporangia were formed from surface cells that were quadrate or rectangular in surface view. Unilocular sporangia were not...

The red algal genus Platoma Schmitz (Schizymeniaceae, Nemastomatales) with type Platoma cyclocolpum (Montagne) Schmitz was originally described from the Canary Islands. Life history studies were conducted on P. cyclocolpum from the Azores under 10uC/8:16 light (L):dark (D), 15uC/16:8 L:D, and 23uC/natural daylight regimes in culture. Three nonrepro...

The Peyssonneliaceae Denizot comprises a worldwide group of non-calcified or calcified, crust-forming red algae found in diverse, intertidal to deep subtidal marine habitats. Eight genera have been recognized in the family, with Peyssonnelia Decaisne having the largest number of species. Both comparative morphology and rbcL and nuclear LSU rDNA seq...

Kumanoa), and the Sections Aristata, Helminthoidea and Batrachospermum of Batrachospermum. We also provide a new name, B. montagnei, for the illegitimate B. guyanense. This tax-onomic synthesis increases the level of monophyly within the Batrachospermales, but minimises taxonomic change where data are still needed.

The red algal genus Predaea (Rhodophyta, Nemastomataceae, Nemastomatales) currently comprises 20 species found in tropical to temperate waters worldwide. The species going under the name Predaea feldmannii (Nemastomataceae, Nemastomatales) in the Azores is here reduced to subspecies rank as P. feldmannii subsp. azorica on the basis of comparative m...

Gametes of the marine green alga, U. compressa, are biflagellate and pear-shaped, having one eye-spot and varying in size between different mating types. Sexuality of green algae has been defined by the cell size of gametes. However, the relative position of an eyespot and a mating structure to flagellar roots was recently found to be opposite betw...

The effect of nitrogen (N) load and irradiance on morphology, growth and photosyn- thetic performance was studied in the green macroalga Caulerpa prolifera (Forsskål) J. V. Lamouroux from the Gulf of Cádiz (south Spain). Constant growth rates were obtained for thalli growing at dif- ferent N loads, which could be fitted to tissue N using the Droop...

Pertende-se determinar o estado ambiental do meio marinho dos Açores, em específico, relativamente ao Descritor D2 – Espécies não indígenas. Para além do estudo sobre o estado do conhecimento atual sobre “non-indigenous species” (NIS) e bio-invasões marinhas registadas para as águas marinhas da Região Autónoma dos Açores (RAA), está-se a fazer um levantamento in situ destas espécies monitorizando os principais pontos de entrada nas ilhas.
