This paper focus on the biodiversity assessment of Australian inland water. Checklists Spongillida are also provided with biogeographic notes together geographic range all species freshwater sponges in Australia. New discoveries reported from ephemeral habitats Kakadu National Park (Australia Northern Territory). Morphological analyses show that belong to Radiospongilla and Pectispongilla family Spongillidae. cfr. philippinensis shows a single layer radial gemmuloscleres absence tangential...
We report here the first record of five genera Spongillida (Porifera, Demospongiae) in both lentic and lotic water Madagascar discovery a new species genus Corvospongilla from Betsiboka River hydrographic basin. lemuriensis sp. n. diverges all other known its unique combination diagnostic morphotraits (a) sessile gemmules with chambered pneumatic layer within tri-layered theca enveloped by spicular cage dominant acanthostrongyles, (b) acanthostrongyles less frequent acanthoxeas-strongyloxeas...
Data on the freshwater sponge fauna of New Caledonia and Zealand (5 species, 3 genera, 2 families) order Spongillida (Porifera, Demospongiae) is reported in framework an assessment Australasian biodiversity. Literature screening a comparative study by LM SEM these poorly known taxa basis historical recent materials delineated compositions local spongillofauna. Pachyrotula raceki, Oncosclera diahoti Heterorotula caledonensis are endemic to Caledonia, as monospecific genus Pachyrotula. shares...
Abstract Growth dynamics and bioactivity variation of the Mediterranean demosponges Agelas oroides Petrosia ficiformis were investigated over 15 months at Paraggi Colombara within Marine Reserve Portofino Promontory (Mediterranean Sea, Ligurian Italy). For both species, growth rates varied between individuals unaffected by initial sponge size. The two species showed a different trend in pattern: A. did not vary significantly seasons, sites depths; contrast, some P. seasonal pattern,...
Abstract Aim Freshwater planarians may have a wide geographical range despite their assumed low vagility. Found across four continents, Dugesia either an ancient origin on large palaeo landmass, followed by colonisation in different regions before continental fragmentation, or more recent and subsequent transoceanic dispersal. We seek to resolve between these two hypotheses. Location Africa, Eurasia Australasia. Taxon Genus (Platyhelminthes: Tricladida: Dugesiidae). Methods used data from...
Despite the fact that South East (SE) Asia is considered as a biodiversity hotspot, knowledge of sessile invertebrates such freshwater sponges (Porifera: Haplosclerida: Spongillina) in this region poor and scarcely reported. For synopsis, diversity distribution SE Asian inland water reported on basis available literature recent assessment Lower Mekong basin. A diagnostic key families/genera from provided together with Light Microscopy Scanning Electron protocols to prepare basic spicular...
An overview of the reproductive patterns seven model species triclads belonging to genus Dugesia from circum-Mediterranean and Afrotropical freshwater is provided. Populations can reproduce exclusively sexually or asexually by fissiparity but coexistence both modes displayed some lineages. The comparison data on life cycles as documented in literature with new highlights a wide array potentialities shift an asexual sexual state vice versa fissiparous populations. Life are poorly diversified...
African sponges, particularly freshwater are understudied relative to demosponges in most other geographical regions. Freshwater sponges (Spongillida) likely share a common ancestor; however, their evolutionary history, during radiation into endemic and allegedly cosmopolitan groups, is unclear. of at least 58 species 17 genera four families described from Central Eastern Africa, but the diversity underestimated due limited distinguishable morphological features. The discovery additional...
The present paper describes three new species of freshwater flatworm the genus Dugesia from Madagascar, by applying an integrative approach to taxonomy, combining morphological and molecular information. Further, data uncovered a cryptic diversity, enabling taxonomic assignment several asexual populations already known thus pointing at least two more on Madagascar. redefines character state conditions in Dugesia, relating types accessory structures copulatory apparatus: penial annexes,...
Microbial drug discovery programs rely heavily on accessing bacterial diversity from the environment to acquire new specialized metabolite (SM) lead compounds for therapeutic pipeline. Therefore, knowledge of how commonly culturable taxa are distributed in nature, addition degree variation SM production within those taxa, is critical informing these front-end efforts and making overall sample collection library creation process more efficient. In current study, we employed MALDI-TOF mass...
Abstract The type material of Spongilla lacustris, recently found in the Linnean herbarium, is described. Type locality and present distribution are shown. Morphological diagnostic traits described by SEM microphotography. This single species Porifera out 12 Linnaeus 1759, with specimen known. A lectotype selected from two syntypes.
The discovery of conspicuous populations the rare species Petrobiona massiliana is reported from shallow water karstic caves Sardinia. morphological comparative analysis versus previous data entire geographic range highlights that spicular traits seem to be highly conservative in contrast with a notable plasticity growth form. Lifestyle and adaptive strategies favoured successful spread P. its persistence as extremely isolated fragmented habitat are discussed together potential environmental...
A first record of the genus Aciculites in Mediterranean Sea and description mediterranea sp. nov. are here presented from a faunistic survey dark shallow marine cave north-western Sardinian karstic area. The new species is characterized by massive cerebellum-like growth form, peculiar distribution inhalant exhalant areas, respectively, depressed elevated portions sponge surface. Oscules show long narrow atrial cavity. Ectosomal skeleton made tangential anisostrongyles on more or less...
The paper focuses on the long-term taxonomic composition and distribution of shallow-water sponge fauna from meromictic–anchialine coastal basin Faro Lake (Southern Italy), comparing recent qualitative field data with literature over a 50-year period. shallow water currently hosts 24 conspicuous species Porifera belonging to 21 genera, 18 families, eight orders, three subclasses two classes, i.e. Demospongiae (23) Calcarea (one). comparison between present past status showed high turnover,...
Thromboembolic conditions are the most common cause of death in developed countries. Anticoagulant therapy is treatment choice, and heparinoids warfarin adopted drugs. Sulphated polysaccharides extracted from marine organisms have been demonstrated to be effective alternatives, blocking thrombus formation by inhibiting some factors involved coagulation cascade. In this study, four acidic glycan fractions sponge Sarcotragus spinosulus were purified anion-exchange chromatography, their...
