Abstract Late in summer 2003, extensive mass mortality of at least 25 rocky benthic macro‐invertebrate species (mainly gorgonians and sponges) was observed the entire Northwestern (NW) Mediterranean region, affecting several thousand kilometers coastline. We were able to characterize event by studying six areas covering main regions NW basin. The degree impact on each study area quantified 49 sites estimating proportion colonies affected populations gorgonian compared with reference data...
Summer conditions in the Mediterranean Sea are characterized by high temperatures and low food availability. This leads to “summer dormancy” many benthic suspension feeders due energetic constraints. Analysis of most recent 33-year temperature time series demonstrated enhanced stratification global warming, which produced a ≈40% lengthening summer conditions. Many biological processes expected be affected this trend, culminating such events as mass mortality invertebrates. Climatic anomalies...
Accurate measurement of clonal genotypes, mutational processes, and replication states from individual tumor-cell genomes will facilitate improved understanding tumor evolution. We have developed DLP+, a scalable single-cell whole-genome sequencing platform implemented using commodity instruments, image-based object recognition, open source computational methods. Using we generated resource 51,926 matched cell images diverse types including lines, xenografts, diagnostic samples with limited...

Summary Most marine sponges establish a persistent association with wide array of phylogenetically and physiologically diverse microbes. To date, the role these symbiotic microbial communities in metabolism nutrient cycles sponge‐microbe consortium remains largely unknown. We identified quantified associated three common Mediterranean sponge species, Dysidea avara , Agelas oroides Chondrosia reniformis ( Demospongiae ) that cohabitate coralligenous community. For each we uptake release...
Coral-excavating sponges are the most important bioeroders on Caribbean reefs and increase in abundance throughout region. This is commonly attributed to a concomitant food availability due eutrophication pollution. We therefore investigated uptake of organic matter by two coral-excavating Siphonodictyon sp. Cliona delitrix tested whether they capable consuming dissolved carbon (DOC) as part their diet. A device for simultaneous sampling water inhaled exhaled was used directly measure...
This study describes in vivo cell turnover (the balance between proliferation and loss) eight marine sponge species from tropical coral reef, mangrove temperate Mediterranean reef ecosystems. Cell was determined through the incorporation of 5-bromo-2′-deoxyuridine (BrdU) measuring percentage BrdU-positive cells after 6 h continuous labeling (10 for Chondrosia reniformis). Apoptosis identified using an antibody against active caspase-3. loss shedding studied quantitatively by collecting...
Marine sponges host bacterial communities with important ecological and economic roles in nature society, yet these benefits depend largely on the stability of host-symbiont interactions their susceptibility to changing environmental conditions. Here, we investigated temporal complex host-microbe symbioses a temperate, seasonal environment over three years, targeting across range symbiont density (high low microbial abundance, HMA LMA) taxonomy (six orders). Symbiont profiling by terminal...
Sponges are the oldest known extant animal-microbe symbiosis. These ubiquitous benthic animals play an important role in marine ecosystems cycling of dissolved organic matter (DOM), largest source on Earth. The conventional view DOM through microbial processing has been challenged by interaction between this efficient filter-feeding host and its diverse abundant microbiome. Here we quantify, for first time, cells symbionts sponge heterotrophy. We combined stable isotope probing nanoscale...
Sponges play an important ecological function in many benthic habitats. They filter large volumes of water, retain suspended particles with high efficiency, and process dissolved compounds. Nevertheless, the factors that regulate sponge pumping rate its relation to environmental have been rarely studied. We examined, situ, variation rates for five Mediterranean species relationship temperature, particulate food abundance size over two annual cycles. Surprisingly, temperature concentration...
Marine animal forests (MAFs) are benthic ecosystems characterised by biogenic three-dimensional structures formed suspension feeders such as corals, gorgonians, sponges and bivalves. They comprise highly diversified communities among the most productive in world's oceans. However, MAFs decline due to global local stressors that threaten survival growth of their foundational species associated biodiversity. Innovative scalable interventions needed address degradation increase resilience under...
Paramuricea clavata (Risso, 1826) is a typical gorqonian species of sublittoral communities found on rocky substrates in the Mediterranean Sea.The reproductive biology this was studied from 1990 to 1992 off Medes Islands (northwestern Mediterranean).P. dioecious.The sex ratio 1:l.Oogenesis lasted 13 and 18 mo, beginning between February July culminating release (SD = 2.2) mature eggs per polyp during summer (June July) following year.Maximum egg diameter vaned 400 500 urn.Male gonads...
Coastal marine protected areas (MPAs) are usually established with an aim to protect of special ecological value. However, tend attract more tourism and associated recreational activities, thereby exposing the biota new risks such as high diving activity. The effects these drawbacks still little known for low‐dynamic systems one most characteristic fragile Mediterranean communities, coralligenous community. Mortality rates were assessed in both heavily dived lightly evaluate effect on...
We evaluated rates of carbon and nitrogen ingestion from particulate organic matter dissolved inorganic excretion by six common sponge species Mediterranean sublittoral rocky bottom habitats. Clearance varied 4 cm 3 dry weight (dry wt) −1 min to 41 , depending on cell type species. Carbon picoplankton the different sponges ranged 0.17 µg C g wt 1.5 2 nmol N 13 . Although compounds between species, most exhibited ability excrete significant amounts nitrate with nitrification 3–13 Only one (...
Abstract Sponges are commonly divided into high (HMA) and low (LMA) microbial‐abundance species according to the bacterial biomass in their tissue. These two groups reflect distinct aquiferous structures feeding strategies. In NW Mediterranean coralligenous community, HMA LMA sponges often packed dense, multispecies assemblages that cover many pinnacles overhangs. We investigated metabolism of cohabitate community by sampling situ inhaled exhaled water. consumed plankton, dissolved organic...
Ocean acidification is increasing and affects many marine organisms. However, certain sponge species can withstand low-pH conditions. This may be related to their complex association with microbes. We hypothesized that greater microbial diversity develop functional redundancy could enable the holobiont survive even if particular microbes are lost at evaluated effects of on growth associated three ubiquitous Mediterranean sponges by exposing them present pH level predicted for year 2100....
