Currently I am working as a curator and researcher at the Marine Biological Reference Collections at the ICM-CSIC, Barcelona, Spain. My research interest is the gelatinous zooplankton: jellyfish, siphonophores, hydromedusae, salps and pyrosoms. I am specialised on morphological species identification: TAXONOMY, which is (nowadays) an old fashion and slow science but the first and basic step in many other disciplines (ecology, evolution, medicine, assessment of living resource stocks, …).
January 2007 - December 2008
- Gelatinous zooplankton and oceanography studies.
August 2004 - August 2005
- Biologist trainee
- Jellyfish culture and feeding behavior studies.
Presentation of the Marine Biological Reference Collections of the ICM-CSIC, Barcelona, Spain. The Marine Biological Reference Collections (CBMR) are specialized mainly in Chordata (fish), Arthropoda and Mollusca, mostly from the Mediterranean Sea, but also with important contributions from the Atlantic Ocean and the rest of the world’s oceans (see...
A review of all reliable worldwide records (from literature and other sources) for the species Bathyphysa conifera has been carried out in order to gain a better knowledge of the present known distribution of this species, both geographical and bathymetric.
The rarely observed cystonect siphonophore Bathyphysa conifera was recorded for the first time in shallow depth water (- 16 m) as a live specimen, at the entrance to the Mediterranean Sea by SCUBA divers. It is a delicate oceanic species, with earlier records coming mostly from deep water, where it readily adheres to deep sea fishing cables and net...
The marine Biological Reference Collections (CBR) are located at the Institute of Marine Sciences (ICM-CSIC) in Barcelona, Spain. The CBR are a Unit of Service where around 15000 referenced species are preserved, catalogued and maintained for their study. The most represented groups at the CBR are fish, crustaceans, molluscs and echinoderms, but al...
Two beaching events of the calycophoran siphonophore Abylopsis tetragona (Otto, 1823) were observed in two different areas of the Strait of Gibraltar during the cold season. The first was discovered on November 2014, on Getares Beach (Algeciras Bay, Mediterranean part of the Strait of Gibraltar), where more than 700 colonies were found deposited al...
In the present work, possible long-term changes in the planktonic cnidarian community were investigated by analyzing (1) species and community spatial distribution patterns, (2) variations in abundance and (3) changes in species richness during three mesoscale surveys representative of the climatic and anthropogenic changes that have occurred durin...
Knowing the variations of planktonic cnidarians under climate change conditions is of importance due to the key role of carnivorous gelatinous zooplankton in the pelagic ecosystem. We investigated the abundance, spatial distribution, species richness and community structure of planktonic cnidarians in a temperate area, the NW Mediterranean, during...
Planktonic cnidarians are those species or their life stages in the phylum Cnidaria that spent their life in the water column and, therefore, are tightly linked to oceanographic dynamics and water mass structures, such as fronts, and environmental gradients. The objective of this thesis is to understand the variability of the planktonic cnidarian c...
We investigated the variability in the mesoscale distribution of the siphonophore Muggiaea atlantica and the hydromedusa Aglaura hemistoma in relation to the rapid spatial oscillations of the shelf-slope front off the Catalan coast (NW Mediterranean). Three extensive surveys were carried out in spring at ten-day intervals. High variability in the p...
Pirosomatida, the only colonial order within the class Thaliacea, is still a little-known group of marine gelatinous animals inhabiting warm and temperate waters of all oceans that may form immense swarms. Pyrosoma atlanticum is the most widespread and common species of pyrosomid between 50º N and 50º S and the only species recorded so far in the M...
Two mass stranding events of the calicophoran siphonophore Abylopsis tetragona (Otto, 1823) were detected in two different areas of the Strait of Gibraltar during the cold season. This case is a good example of citizen science and jellyfish scientific knowledge outreach in schools, thanks to that we received the warning of the event and collaborate...
Salps are pelagic tunicates with high feeding, growth and fecal pellet production rates. These features allow them to efficiently graze on algal blooms, rapidly developing dense populations which mediate significant fluxes of organic matter to the bottom. Their complex life cycle, ephemeral appearance and patchy distribution make them difficult to...
The "Biogeographic Atlas of the Southern Ocean" is a legacy of the International Polar Year 2007-2009 (www.ipy.org) and of the Census of Marine Life 2000-2010 (www.coml.org), contributed by the Census of Antarctic Marine Life (www.caml.aq) and the SCAR Marine Biodiversity Information Network (www.scarmarbin.be; www.biodiversity.aq). The "Biogeograp...
One of the most important weakness in the analyses of the interannual mesoscale shifts in planktonic communities is that the studies have rarely been done at the same spatial scale, have not covered the same area or have not used the same sampling methodology. To solve this problem, the Institute of Marine Sciences (ICM-CSIC) have been conducting c...
The order Siphonophora, free-swimming colonial pelagic hydrozoans (Cnidaria), has the greatest degree of polymorphism and functional specialization and the most complex organization of all colonial animals. For those reasons and their fragility, they are very difficult to study, and many of described earlier species require a complement or expansio...
The ctenophore Mnemiopsis leidyi, a species native to estuaries and coastal regions of the western Atlantic Ocean, was first introduced into the Black Sea in the early 1980s, where it negatively affected zooplankton biodiversity and biomass, and commercial fisheries. This invasive ctenophore was first reported along the Spanish Mediterranean coast...
The special location (40?42°S in the Southwestern Atlantic Ocean) and the hydrodynamic regime (limited water exchange with open ocean) in San Matías Gulf (Argentina) seem to produce a particular fauna of planktonic cnidarians whose their abundances are mainly shaped by the Gulf circulation. Four oceanographic cruises, covering 93 stations in three...
Specific richness, abundance and distribution of planktonic cnidarians from San Matías Gulf (SMG; 40° 50' ‐ 42° 15' S and 63° 05' ‐ 65° 10' W) and adjacent areas (San Jose Gulf and Argentine continental shelf contiguous to SMG) were studied over a seasonally cycle. SMG is a semi‐enclosed area with an important seasonally oceanographic influence fro...
Congratulations for your interesting project. I wonder if you include the study of Siphonophores (Cnidaria) and/or other gelatinous zooplankton in your project? I would be very interested in knowing which gelatinous groups you study.
I also offer my collaboration as a gelatinous zooplankton taxonomist with more than 19 years of experience analyzing zooplankton samples.
All the best,
The Biological Reference Collections (CBR) of the ICM-CSIC are formed by specimens of marine organisms, properly identified, organized, preserved and guarded, with referential purposes, available to the international scientific community. In studies of taxonomy, biodiversity, biogeography or population genetics, they constitute a reference for research and publications, and are a tool of diffusion of the generated knowledge. http://cbr.icm.csic.es/en
