Article
Full-text available
Clonal plants can reproduce sexually and clonally, expressing different proportions of these different life histories in distinctive environments. In seagrass meadows, light attenuation hinders marine plant colonization in deeper areas of its vertical distribution. Therefore it is expected that the fluorescence maximum quantum yield of seedlings wi...

Some of the major challenges in seagrass restoration on exposed open coasts are the choice of transplant design that is optimal for coastlines periodically exposed to high water motion, and understanding the survival and dynamics of the transplanted areas on a long time-scale over many years. To contribute to a better understanding of these challen...

Marine flowering plants can reproduce sexually and clonally, and the relative contribution of these two modes can be dependent on the environmental conditions. Zostera marina, a seagrass widely distributed in the northern hemisphere, can form annual and perennial meadows with different proportions of sexual versus clonal propagation depending on th...
Article
The present study was carried out in the marine area of Stratoni, Greece, where two seahorse species are present (Hippocampus hippocampus and H. guttulatus). Two surveys were conducted (September 2016, May 2019) to gather information regarding seahorse species' abundance, distribution and habitat characteristics. Four different seahorse natural and...
Preprint
The accurate delimitation of species boundaries in non-bilaterian marine taxa is notoriously difficult, with consequences for many studies in ecology and evolution. Anthozoans are a diverse group of key structural organisms worldwide, but the lack of reliable morphological characters and informative genetic markers hampers our ability to understand...
Article
Seagrass meadows in São Tomé and Príncipe, eastern Atlantic Ocean, are described here for the first time. Specifically, we quantified the biomass and density of seagrasses, characterized the plant morphology and measure their nutrient content as a proxy of the nutrient environmental conditions where the meadows develop. The seagrass Halodule wright...

The westernmost occurrence of Caulerpa prolifera on the Atlantic European coast has been accepted in recent decades, to be Huelva province, southern Spain. In April 2011, this species was found in Ria Formosa, southern Portugal, extending its westernmost limit along the Iberian Peninsula coastline. In the course of research into this species it was...

The general aim of this project was to address the current lack of knowledge on the biodiversity, ecology and conservation status of deep (>30 m) rocky marine habitats in Portugal, a subject that was poorly addressed previously. A PhD thesis was developed within the scope of project Deep Reefs (ww.deepreefs.com), initially developed by volunteer divers in 2010, later with funding support (see Acknowledgements), to survey, compile and consolidate knowledge on rocky reef assemblages occurring at mesophotic depths, to provide scientific information that will help conservation efforts and to extend the marine European Natura 2000 network below 30 m depth in Portugal. The specific aims of the thesis are to: 1. Address methodologies available to study the circalittoral/mesophotic assemblages assemblages and identify the benefits and constraints of two video sampling techniques (paper 1, Chapter 2); 2. Describe a deep red coral, Corallium rubrum, assemblage off the southern coast of Portugal with conservation implications and indicate conservation priorities (paper 2, Chapter 3); 3. Identify the environmental factors controlling the suitable habitat map for an octocoral occurring at mesophotic depths, Paramuricea clavata, with conservation concerns (paper 3, Chapter 4); 4. Study the genetic connectivity patterns of the vulnerable octocoral, P. clavata, at broad (Mediterranean-Atlantic) and local (Portugal) scales (paper 4, Chapter 5).

The project will deliver a first assessment of the distribution and extent of seagrass meadows in São Tomé and Príncipe and implement a seagrass monitoring and conservation program. Results will contribute to the conservation of healthy seagrass beds in the archipelago with benefit for local communities.
