Sponge Mass Mortalities in a Warming Mediterranean Sea: Are Cyanobacteria-Harboring Species Worse Off?
Mass mortality events are increasing dramatically in all coastal marine environments. Determining the underlying causes of mass mortality events has proven difficult in the past because of the lackExpand
Siliceous spicules and skeleton frameworks in sponges: Origin, diversity, ultrastructural patterns, and biological functions
Silica deposition is a fundamental process in sponges. Most sponges in the Classes Demospongiae and Hexactinellida secrete siliceous elements, which can subsequently fuse, interlock with each other,Expand
Decline in Mesozoic reef-building sponges explained by silicon limitation
Several unrelated clades of siliceous sponges proliferated on the shelves of the Jurassic Tethys Sea, becoming prominent builders in reefs and near-shore mounds. Many of these builders areExpand
Clearance rates and aquiferous systems in two sponges with contrasting life‐history strategies
The clearance rates and microarchitecture of the aquiferous systems of two sympatric sponge species, Crambe crambe (Schmidt) and Dysidea avara (Schmidt), are compared. We performed a filtrationExpand
Growth dynamics and mortality of the encrusting sponge Crambe crambe (Poecilosclerida) in contrasting habitats : correlation with population structure and investment in defence
1. A trade-off was predicted between investment in defence and growth rate in the encrusting sponge Crambe crambe (Schmidt), while survival rates were expected to correlate positively with theExpand
The Sponge Population of the Cabrera Archipelago (Balearic Islands): Characteristics, Distribution, and Abundance of the Most Representative Species
. The abundance, distribution, and species richness of the littoral sponges (0–55 m) from the Cabrera Archipelago (Balearic Islands) were studied along light gradients from the surface to the seaExpand
Biogeography of sponge chemical ecology: comparisons of tropical and temperate defenses
Examples from both marine and terrestrial systems have supported the hypothesis that predation is higher in tropical than in temperate habitats and that, as a consequence, tropical species haveExpand
Benthic assemblages in two Mediterranean caves: species diversity and coverage as a function of abiotic parameters and geographic distance
Benthic assemblages of two Mediterranean submarine caves were compared. Species coverage and number of species were lower in internal (dark) communities than external. This feature was speciallyExpand
Sponges as biomonitors of heavy metals in spatial and temporal surveys in northwestern mediterranean: multispecies comparison.
Contamination by heavy metals has increased drastically in the coastal Mediterranean during the last 20 years. A comparative study on metal bioaccumulation by four widespread sponge species (CrambeExpand
Silica deposition in Demosponges: spiculogenesis in Crambe crambe
Abstract. Transmission electron-microscopy images coupled with dispersive X-ray analysis of the species Crambe crambe have provided information on the process of silica deposition in Demosponges.Expand
