    Samudra Report No.88, December 2022 (2023)
    International Collective in Support of Fishworkers (ICSF) | India
    Details
    Publication Date: 2023-04-07
    Description: The International Collective in Support of Fishworkers (ICSF) has released the latest edition of its popular fisheries publication – SAMUDRA Report, its triannual journal on fisheries, communities and livelihoods. SAMUDRA Report No. 88, dated December 2022, has a special focus on the International Year of Artisanal Fisheries and Aquaculture (IYAFA 2022), with reports from several regions of how the year was celebrated as well as the ICSF Statements made at the IYAFA 2022 Asia Workshop. The editorial Comment points to how the abiding message of IYAFA 2022 should be that the social pillar of sustainable development ought to be strengthened to protect the future of lives and livelihoods in the small-scale fisheries subsector. A report from the United Nations Oceans Conference 2022 details how representatives of small-scale fishing communities – the most numerous ocean users –launched a Call to Action in a conerence that brought together two main protagonists: those clamouring for reforms in ocean governance to ‘Save Our Ocean’, and those clamouring for reforms to open up the ‘Blue Economy’. The article from Taiwan says that securing the rights of migrant workers in the nation’s fisheries is an ongoing and evolving process...

    Eight new Halophytophthora species from marine and brackish-water ecosystems in Portugal and an updated phylogeny for the genus (2022)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 48, pp. 54-90
    Details
    Publication Date: 2024-03-24
    Description: During an oomycete survey in December 2015, 10 previously unknown Halophytophthora taxa were isolated from marine and brackish water of tidal ponds and channels in saltmarshes, lagoon ecosystems and river estuaries at seven sites along the Algarve coast in the South of Portugal. Phylogenetic analyses of LSU and ITS datasets, comprising all described Halophytophthora species, the 10 new Halophytophthora taxa and all relevant and distinctive sequences available from GenBank, provided an updated phylogeny of the genus Halophytophthora s.str. showing for the first time a structure of 10 clades designated as Clades 1–10. Nine of the 10 new Halophytophthora taxa resided in Clade 6 together with H. polymorphica and H. vesicula. Based on differences in morphology and temperature-growth relations and a multigene (LSU, ITS, Btub, hsp90, rpl10, tigA, cox1, nadh1, rps10) phylogeny, eight new Halophytophthora taxa from Portugal are described here as H. brevisporangia, H. celeris, H. frigida, H. lateralis, H. lusitanica, H. macrosporangia, H. sinuata and H. thermoambigua. Three species, H. frigida, H. macrosporangia and H. sinuata, have a homothallic breeding system while the remaining five species are sterile. Pathogenicity and litter decomposition tests are underway to clarify their pathological and ecological role in the marine and brackish-water ecosystems. More oomycete surveys in yet undersurveyed regions of the world and population genetic or phylogenomic analyses of global populations are needed to clarify the origin of the new Halophytophthora species.

    Multiple new Phytophthora species from ITS Clade 6 associated with natural ecosystems in Australia: evolutionary and ecological implications (2011)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 26 no. 1, pp. 13-39
    Details
    Publication Date: 2024-01-12
    Description: During surveys of dying vegetation in natural ecosystems and associated waterways in Australia many new taxa have been identified from Phytophthora ITS Clade 6. For representative isolates, the region spanning the internal transcribed spacer region of the ribosomal DNA, the nuclear gene encoding heat shock protein 90 and the mitochondrial cox1 gene were PCR amplified and sequenced. Based on phylogenetic analysis and morphological and physiological comparison, four species and one informally designated taxon have been described; Phytophthora gibbosa, P. gregata, P. litoralis, P. thermophila and P. taxon paludosa. Phytophthora gibbosa, P. gregata and P. taxon paludosa form a new cluster and share a common ancestor; they are homothallic and generally associated with dying vegetation in swampy or water-logged areas. Phytophthora thermophila and P. litoralis are sister species to each other and more distantly to P. gonapodyides. Both new species are common in waterways and cause scattered mortality within native vegetation. They are self-sterile and appear well adapted for survival in an aquatic environment and inundated soils, filling the niche occupied by P. gonapodyides and P. taxon salixsoil in the northern hemisphere. Currently the origin of these new taxa, their pathogenicity and their role in natural ecosystems are unknown. Following the precautionary principle, they should be regarded as a potential threat to native ecosystems and managed to minimise their further spread.

    Baffling shades of blue: Addressing the impacts of the blue economy on small-scale fisheries in Latin America (2024)
    International Collective in Support of Fishworkers (ICSF) | India
    Details
    Publication Date: 2024-01-08
    Description: The incessant noise over ‘Blue Economy’ and ‘Blue Growth’ leaves artisanal and small-scale fishers dazed and confused. This report works through that confusion. It draws on scholarship from the trenches and the research centres across ten Latin American countries. From extensive interviews, policy reviews, analyses of finances and online datasets. In granular detail, it examines how Blue Growth affects artisanal fishers and their need for equity and justice. Through the baffling shades of blue—conflicts, priorities, the politics of managing our coasts and seas—this report finds clear light. It lays down the agenda for fishworkers and organizations working for them.

    Phylogeography of the Sponge Suberites diversicolor in Indonesia: insights into the evolution of marine lake populations (2013)
    In:  PLoS ONE vol. 10 no. 8
    Details
    Publication Date: 2024-01-12
    Description: The existence of multiple independently derived populations in landlocked marine lakes provides an opportunity for fundamental research into the role of isolation in population divergence and speciation in marine taxa. Marine lakes are landlocked water bodies that maintain a marine character through narrow submarine connections to the sea and could be regarded as the marine equivalents of terrestrial islands. The sponge Suberites diversicolor (Porifera: Demospongiae: Suberitidae) is typical of marine lake habitats in the Indo-Australian Archipelago. Four molecular markers (two mitochondrial and two nuclear) were employed to study genetic structure of populations within and between marine lakes in Indonesia and three coastal locations in Indonesia, Singapore and Australia. Within populations of S. diversicolor two strongly divergent lineages (A & B) (COI: p = 0.4% and ITS: p = 7.3%) were found, that may constitute cryptic species. Lineage A only occurred in Kakaban lake (East Kalimantan), while lineage B was present in all sampled populations. Within lineage B, we found low levels of genetic diversity in lakes, though there was spatial genetic population structuring. The Australian population is genetically differentiated from the Indonesian populations. Within Indonesia we did not record an East-West barrier, which has frequently been reported for other marine invertebrates. Kakaban lake is the largest and most isolated marine lake in Indonesia and contains the highest genetic diversity with genetic variants not observed elsewhere. Kakaban lake may be an area where multiple putative refugia populations have come into secondary contact, resulting in high levels of genetic diversity and a high number of endemic species.

    Malassezia vespertilionis sp. nov.: a new cold-tolerant species of yeast isolated from bats (2018)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 41, pp. 56-70
    Details
    Publication Date: 2024-01-12
    Description: Malassezia is a genus of medically-important, lipid-dependent yeasts that live on the skin of warmblooded animals. The 17 described species have been documented primarily on humans and domestic animals, but few studies have examined Malassezia species associated with more diverse host groups such as wildlife. While investigating the skin mycobiota of healthy bats, we isolated a Malassezia sp. that exhibited only up to 92 % identity with other known species in the genus for the portion of the DNA sequence of the internal transcribed spacer region that could be confidently aligned. The Malassezia sp. was cultured from the skin of nine species of bats in the subfamily Myotinae; isolates originated from bats sampled in both the eastern and western United States. Physiological features and molecular characterisation at seven additional loci (D1/D2 region of 26S rDNA, 18S rDNA, chitin synthase, second largest subunit of RNA polymerase II, \xce\xb2-tubulin, translation elongation factor EF-1\xce\xb1, and minichromosome maintenance complex component 7) indicated that all of the bat Malassezia isolates likely represented a single species distinct from other named taxa. Of particular note was the ability of the Malassezia sp. to grow over a broad range of temperatures (7\xe2\x80\x9340 \xc2\xb0C), with optimal growth occurring at 24 \xc2\xb0C. These thermal growth ranges, unique among the described Malassezia, may be an adaptation by the fungus to survive on bats during both the host\xe2\x80\x99s hibernation and active seasons. The combination of genetic and physiological differences provided compelling evidence that this lipid-dependent yeast represents a novel species described herein as Malassezia vespertilionis sp. nov. Whole genome sequencing placed the new species as a basal member of the clade containing the species M. furfur, M. japonica, M. obtusa, and M. yamatoensis. The genetic and physiological uniqueness of Malassezia vespertilionis among its closest relatives may make it important in future research to better understand the evolution, life history, and pathogenicity of the Malassezia yeasts.

    Six new Phytophthora species from ITS Clade 7a including two sexually functional heterothallic hybrid species detected in natural ecosystems in Taiwan. (2017)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 38, pp. 100-135
    Details
    Publication Date: 2024-01-12
    Description: During a survey of Phytophthora diversity in natural ecosystems in Taiwan six new species were detected. Multigene phylogeny based on the nuclear ITS, \xc3\x9f-tubulin and HSP90 and the mitochondrial cox1 and NADH1 gene sequences demonstrated that they belong to ITS Clade 7a with P. europaea, P. uniformis, P. rubi and P. cambivora being their closest relatives. All six new species differed from each other and from related species by a unique combination of morphological characters, the breeding system, cardinal temperatures and growth rates. Four homothallic species, P. attenuata, P. flexuosa, P. formosa and P. intricata, were isolated from rhizosphere soil of healthy forests of Fagus hayatae, Quercus glandulifera, Q. tarokoensis, Castanopsis carlesii, Chamaecyparis formosensis and Araucaria cunninghamii. Two heterothallic species, P. xheterohybrida and P. xincrassata, were exclusively detected in three forest streams. All P. xincrassata isolates belonged to the A2 mating type while isolates of P. xheterohybrida represented both mating types with oospore abortion rates according to Mendelian ratios (4\xe2\x80\x9333 %). Multiple heterozygous positions in their ITS, \xc3\x9f-tubulin and HSP90 gene sequences indicate that P. xheterohybrida, P. xincrassata and P. cambivora are interspecific hybrids. Consequently, P. cambivora is redescribed as P. xcambivora without nomenclatural act. Pathogenicity trials on seedlings of Castanea sativa, Fagus sylvatica and Q. suber indicate that all six new species might pose a potential threat to European forests.
