Abstract:
Twenty sponge species (totalling 190 individuals) were collected during the 1938, 1994 and 2004/5 expeditions to the remote island of Clipperton in the East Pacific Ocean. Seven species are widespread Indo-Pacific sponges; nine species comprise sponges new to science; four species were represented only by small thin patches insufficient for proper characterization and could be only determined to genus. The new species may not be necessarily endemic to the island, as several show similarities with species described from elsewhere in the East and West Pacific. Four species: Tethya sarai Desqueyr

Abstract:
Sponges interact with most other organisms in marine systems as competitors, symbionts, hosts of symbionts, consumers, and prey. Considerable creative energy has been required to study and describe the amazing variety of sponge interactions, as sponges can hide symbionts deep inside, rapidly regenerate wounds from grazers, carry on important associations with unculturable microscopic organisms, and otherwise foil attempts to determine how they are interacting with other organisms. This review of sponge interactions covers (i) competition among sponge species, and between sponges and other sess

Abstract:
Pregnancy rate and prolificacy were studied in ewes after cycle synchronisation by either progestagen sponges plus equine chorionic gonadotrophin (eCG) or by three injections of prostaglandin (PG). We also tested whether there was any advantage in treating the sponges with antibiotic before insertion. In Experiment 1, 207 Corriedale ewes were treated with intravaginal sponges for 14 days and given 250 IU eCG at sponge withdrawal. For half of the ewes, the sponges had been sprayed with chlortetracycline whereas the other half received untreated sponges. Ewes were ranked within each group based

Abstract:
Abstract The chemical ecology and chemical defenses of sponges have been investigated for decades; consequently, sponges are among the best understood marine organisms in terms of their chemical ecology, from the level of molecules to ecosystems. Thousands of natural products have been isolated and characterized from sponges, and although relatively few of these compounds have been studied for their ecological functions, some are known to serve as chemical defenses against predators, microorganisms, fouling organisms, and other competitors. Sponges are hosts to an exceptional diversity of micr

Abstract:
Abstract Sponges perceive and respond to a range of stimuli. How they do this is still difficult to pin down despite now having transcriptomes and genomes of an array of species. Here we evaluate the current understanding of sponge behavior and present new observations on sponge activity in situ. We also explore biosynthesis pathways available to sponges from data in genomes/transcriptomes of sponges and other non-bilaterians with a focus on exploring the role of chemical signaling pathways mediating sponge behavior and how such chemical signal pathways may have evolved.

Abstract:
The fossil record of sponges is a very old one, and begins in the Precambrian, but is rather incomplete. Only those sponges with a rigid skeleton, i.e., Hexactinosida and Lychniscosida (both hexactinellids), lithistids (demosponges with desmas), and sponges with a massive calcareous skeleton (polyphyletic demosponges and Calcarea) have a more or less continuous fossil record that is, however, inadequately studied, especially from the Tertiary. The beginning of sponge diversification during the Cambrian is relatively well known thanks to their very good preservation, from the Chengjiang fauna i

Abstract:
Sponges secrete a variety of mineral skeletons consisting of calcite, aragonite, and (or) amorphous silica that confer strength and protect them from physical perturbations. Calcification takes place in a solution of bicarbonate and calcium ions, which is supersaturated with respect to both calcite and aragonite. In contrast, siliceous spicules are formed from an environment that is undersaturated with respect to silicon. Silification is the predominant process of biomineralization in extant sponges (92% of the species). The number of axes of symmetry in the large skeletal elements (megasclere

Abstract:
The diversity of animal social strategies has interested evolutionary biologists since the time of Darwin. Eusociality—the apex of animal sociality—traditionally characterized by cooperative offspring care, overlapping generations and reproductive division of labor, was until recently known only in insects and a few vertebrate species. The independent evolution of eusociality in shrimps in the genus Synalpheus offers a unique opportunity to test the generality of social evolution theories that are based mainly on insects and social vertebrates. The genus Synalpheus is particularly ideal for co

Abstract:
Many antrophic activities release pollutants to the marine environment. Among them heavy metals are of great importance, since they are conservative pollutants, which can be accumulated through trophy chains. Sometimes, the liberation to the marine waters is acute and drastic, leading to massive mortalities. However, more often, the liberation is by means of low and chronic concentrations. The main objective of the present thesis is to analyze the sponge responses in face to sublethal concentrations of heavy metals and to determine, if it is possible, whether they can be used as biomonitors of
