Assessing the complex sponge microbiota: core, variable and species-specific bacterial communities in marine sponges
TLDR
This global analysis represents the most comprehensive study of bacterial symbionts in sponges to date and provides novel insights into the complex structure of these unique associations. Expand
Climate-driven regime shift of a temperate marine ecosystem
TLDR
It is shown that extreme warming of a temperate kelp forest off Australia resulted not only in its collapse, but also in a shift in community composition that brought about an increase in herbivorous tropical fishes that prevent the reestablishment of kelp. Expand
The Biogeography and Phylogeny of Unicellular Cyanobacterial Symbionts in Sponges from Australia and the Mediterranean
TLDR
The distribution, host associations, and phylogenetic relationships of the unicellular cyanobacterial symbionts of selected marine sponges were investigated and one symbiont was found in diverse sponge genera in the Mediterranean Sea and the Indian, Pacific, and Southern oceans, whereas others were apparently more restricted in host association and distribution. Expand
Marine sponges of the Dampier Archipelago, Western Australia: patterns of species distributions, abundance and diversity
TLDR
The number of species found at only one location was high, supporting previous findings that northwestern Australia has high sponge endemism, andEstimations of diversity based on non-parametric modelling suggests that there are potentially more species than presently recorded in the archipelago. Expand
Reproductive biology of three sponge species of the genus Xestospongia (Porifera: Demospongiae: Petrosida) from the Great Barrier Reef
TLDR
Three species of the Petrosida, Xestospongia bergquistia, X. exigua, and X. testudinaria, were monitored for four years on a fringing reef at Orpheus Island, Great Barrier Reef, Australia and all were oviparous and female reproductive activity began prior to males becoming active. Expand
Immunolocalization of the Plasma Membrane H+ -ATPase in Minor Veins of Vicia faba in Relation to Phloem Loading
TLDR
Results show that the plasma membrane infoldings of transfer cells possess the proton-pumping machinery required to energize an efficient uptake of photosynthates from the phloem apoplast and an efficient retrieval of nitrogenous compounds from the vascular sap. Expand
A new species of cyanobacterial symbiont from the marine sponge Chondrilla nucula
TLDR
Results indicate that the unicellular cyanobacterial symbionts of the sponge species Chondrilla nucula and C. australiensis are the same, and comprise a unique species of cyanobacterium belonging to the genus Synechococcus, and occurs in the surface tissues of these sponges. Expand
Deceptive Desmas: Molecular Phylogenetics Suggests a New Classification and Uncovers Convergent Evolution of Lithistid Demosponges
TLDR
This study provides a framework for further detailed investigations of this important demosponge group and corroborates some previous weakly-supported hypotheses, and provides novel insights into the evolutionary relationships of the previous ‘order Lithistida’. Expand
Descriptions of species of the Haplosclerida (Porifera: Demospongiae) occurring in tropical waters of the Great Barrier Reef
TLDR
The taxonomic study reported in this paper concerns tropical Australian marine sponges assigned to the order Haplosclerida, and fourteen species studied, six are described as new to science, and four are new species records for the region. Expand
Sponges as important sources of nitrate on an oligotrophic continental shelf
TLDR
Observations and measurements of nitrogen release rates from sponges are consistent with the hypothesis that primary production in the region depends on wave-induced mixing at the seabed for resupply of remineralized nitrogen to a nutrient-impoverished water column and that spongees make an important contribution to these fluxes.
