The success of invasive species can be measured by invasiveness, which depicts intrinsic characteristics that enable them to thrive in new environments. In invasive seaweeds, for example, the persistence of multiple overlapping cohorts throughout the year plays a key role in increasing plant cover and exerting unrelenting pressure on invaded areas....
The deep-water species Sargassum trichocarpum J. Agardh is reported in the province of Malaga, and drifted material has been found in the province of Cadiz. These finding highlights that the species is still present on the western Mediterranean coasts despite the threats affecting its populations, which are in a state of decline.
COVID-19 lockdown measures have impacted the environment with both positive and negative effects. However, how human populations have perceived such changes in the natural environment and how they may have changed their daily habits have not been yet thoroughly evaluated. The objectives of this work were to investigate (1) the social perception of...
As the commercial use of seaweed for natural product extraction calls for abundant,
uniform biomass, this study focused on the production and the variability of the
harvested biomass of valuable compounds produced by a commercially relevant red
algal species, Asparagopsis armata . Its tetrasporophyte stage was retrieved from
two Irish localities we...
Asparagopsis (Bonnemaisoniaceae, Rhodophyta) species are distributed in most temperate and tropical waters of the world,
where they are considered an iconic invader. Despite a low number of species in the genus, Asparagopsis armata and A.
taxiformis are considered species complexes, revealing remarkable genetic diversity in native and introduced...
Se detallan las especies de macroalgas invasoras en las costas andaluzas.
Se expone el caso del modelo de distribución realizado para la especie invasora Rugulopteryx okamurae, y se destaca su papel como herramienta para la prevención y gestión

The green invasive macroalgae Ulva ohnoi and U. pertusa are known for their capacity to form Green Tides across many geographic regions. Given their global ecological and economic impact, photosynthetic responses of both Ulva spp. were tested in laboratory experiments using short-term (3 h, 5 h) exposure to different temperatures (27-36 °C) and lig...
Primary production of a population of the red invasive seaweed A. taxiformis from southern Spain was assessed using a demography-based approach and studied in relation to environmental conditions. In-depth analysis of shoots biomass of different size classes revealed a population dynamic characterized by six cyclic cohorts that followed consecutive...
The mitochondrial genetic diversity, distribution and invasive potential of multiple cryptic OTUs of the red invasive seaweed Asparagopsis were assessed by studying introduced Mediterranean and Hawaiian populations. Invasive behavior of each Asparagopsis OTU was inferred from phylogeographic reconstructions, past historical demographic dynamics, re...
Asparagopsis taxiformis is a rhodophycean species composed of six genetic lineages, one of which is considered a relevant invasive component of the Mediterranean flora. In the present study we describe seasonal changes of the structure and biomass of the native community associated to Asparagopsis taxiformis in Granada (Southern Spain). Native comm...
Can the reproductive traits of Asparagopsis taxiformis contribute to its success as an invader? We present the reproductive phenology of a population located in southern Spain and a quantitative study of gametophyte reproductive structures. Reproductive allocation (the proportion of biomass allocated to reproductive tissue) in different size classe...
In this study we present basic population data of the red macroalga Asparagopsis taxiformis, widely recognized as invasive in the Mediterranean Sea. A 13-month field study was carried out on a population located in southern Spain, addressing its phenology, population dynamics and demography. We further tested whether biomass variations were related...
Molecular phylogeography has for decades been a frequently used approach to delineate novel evolutionarily significant units (ESUs) and to study the dynamics of invasive species. Next-generation sequencing technology (NGS) and the use of environmental DNA (eDNA) have the potential to revolutionize our way of understanding biodiversity and to establ...
The red seaweed Asparagopsis taxiformis embodies five cryptic mitochondrial lineages (lineage 1 to 5) introduced worldwide as a consequence of human mediated transport and climate change. We compared globally collected mitochondrial cox2-3 intergenic spacer sequences with sequences produced from multiple Australian locations and South Korea to iden...
Three different species of Caulerpa (Caulerpaceae, Chlorophyta) cooccur in the Mediterranean Sea: two of them are found at the centraleastern basin and are typically considered non aggressive components of the Lessepsian flora [(C. chemnitzia (Esper) J.V. Lamouroux and C. racemosa var. lamourouxii (Turner) Weber-van Bosse f. requienii (Montagne) We...
New records and geographical additions to the benthic marine flora of the Atlantic Iberian Peninsula:
In this work, we provide new records and geographical distribution data for 22 species (10 Rhodophyta, 9 Ochrophyta and 3 Chlorophyta) of seaweeds inhabiting from the intertidal to the deep subtidal of the Atlantic Iberian. Ulva australis is a new...
Three macroalgal species belonging to Chlorophyta (Ulva rigida), Rhodophyta
(Ellisolandia elongata) and Phaeophyceae (Heterokontophyta; Cystoseira tamariscifolia), naturally
growing at the same shore level and representing 3 morpho-functional groups, were exposed
to short-term changes in temperature under different carbon and nitrogen regimes. Expe...
Invasive species display remarkable levels of ecophysiological plasticity, which supports colonization, population establishment and fitness across their introduction range. The red seaweed genus Asparagopsis comprises genetically homogeneous invasive species (A. armata) and cryptic species complexes (A. taxiformis sensu lato) consisting of invasiv...
Alien species are a major cause of extinctions worldwide and are considered as the second threat in order of importance to the planet’s diversity. Macroalgae represent the 20% of the world’s marine introduced species. They directly affect native ecosystems by monopolizing space and modify the composition of local communities.
Asparagopsis taxiform...
This work reports the first record of Desmarestia dudresnayi (Phaeophyceae,
Desmarestiaceae) for Cádiz province (Southern Spain),
representing the southernmost record of this deep habitat species
on the North Atlantic coast. Morphological description of the specimen
is provided.
Rapid identification of introduced seaweeds is crucial to support management and conservation decisions, especially when multiple cryptic lineages of high-profile invasive taxa occur sympatrically. The red seaweed genus Asparagopsis (Bonnemaisoniales, Rhodophyta) comprises two recognised morpho-species characterised by heteromorphic life cycles and...
f Biological invasions are an important element of global change, and represent the second threat in order of importance for global biodiversity. Marine macroalgae are an important component of alien species, ranging between 10 and 40% of total species (Schaffelke et al. 2006). It is known that climate change impacts on many ecological factors such...
