Ramsar site designation is an acknowledgment of a wetland’s importance. In this study, we conducted biodiversity survey around Natuna to examine its eligibility as the next in Indonesia. This was through sampling for biological resources, using either transect, trapping, or visual observation. We surveyed 32 stations endangered and vulnerable fish, water birds, wetland-dependent species. Sample...
Seagrasses around the world are threatened by human activities that degrade water quality and reduce light availability. In this study, light requirements were determined for four common and abundant seagrasses along the Gulf coast of peninsular Florida using a threshold detecting algorithm. Light requirements ranged from 8% to 10% of surface irradiance for Halophila engelmannii to 25-27% of su...
Photoactive yellow protein (PYP) is involved in the negative phototactic response towards blue light of the bacterium Halorhodospira halophila. Here, we report nearly complete backbone and side chain (1)H, (13)C and (15)N resonance assignments at pH 5.8 and 20 °C of PYP in its electronic ground state.
The east coast of Bintan Island is an area that has a wide distribution seagrass with good conditions for the association Strombus sp in ecosystem. This research aims to identify coverage and abundance golden snails (Strombus sp) study sp.) ecosystems on Island. was conducted East Coast from June until July 2021 (Teluk Bakau Village, Malang Rapat Village Berakit Village). tools materials used t...
Novel species of fungi described in this study include those from various countries as follows: Antarctica: Cadophora antarctica from soil. Australia: Alfaria dandenongensis on Cyperaceae, Amphosoma persooniae on Persoonia sp., Anungitea nullicana on Eucalyptus sp., Bagadiella eucalypti on Eucalyptus globulus, Castanediella eucalyptigena on Eucalyptus sp., Cercospora dianellicola on Dianella sp...
A molecular genetic approach was used to elucidate the phylogeographic relationships of clover grass (Halophila baillonii Asch.) from three key regions within its current distributional range. Halophila is a small seagrass that has historically been only found in few locations Caribbean and Atlantic coast Brazil. In past decades H. also observed Eastern Tropical Pacific (ETP). Very little known...
Seagrass beds are the largest organism-built marine habitat in Dominica, yet have only been surveyed since 2007. Standardized examinations along a depth gradient between 0 and 24 m, focusing on magnoliophyte species composition and benthic cover of shoots at 17 seagrass bed sites, were carried out between September 10 and December 7, 2008. The Cymodoceaceae Syringodium filiforme (Kuetzing 1860)...
The molecular structure of a high potential iron-sulfur protein (HiPIP) isolated from the purple photosynthetic bacterium, Ectothiorhodospira halophila strain BN9626, has been solved by x-ray diffraction analysis to a nominal resolution of 2.5 A and refined to a crystallographic R value of 18.4% including all measured x-ray data from 30.0- to 2.5-A resolution. Crystals used in the investigation...
The high-potential iron-sulfur protein (iso-form II) isolated from Ectothiorhodospira vacuolata has been crystallized and its three-dimensional structure determined by molecular replacement procedures and refined to 1.8-A resolution with a crystallographic R factor of 16.3%. Crystals employed in the investigation belonged to the space group C222(1) with unit cell dimensions of a = 58.4 A, b = 6...
