Diversity and spatial distribution of amoA-encoding archaea in the deep-sea sediments of the tropical West Pacific Continental Margin
Provedor de dados: 5
Autores: Dang, H.; Li, J.; Zhang, X.; Li, T.; Tian, F.; Jin, W.
The ecological characteristics of the deep-sea amoA-encoding archaea (AEA) are largely unsolved. Our aim was to study the diversity, structure and distribution of the AEA community in the sediments of the tropical West Pacific Continental Margin, to develop a general view of the AEA biogeography in the deep-sea extreme environment. Archaeal amoA clone libraries were constructed. Diverse and novel amoA sequences were identified, with the Bohol Sea, Bashi Strait and Sibuyan Sea harbouring the highest and the Bicol Shelf the lowest AEA diversity. Phylogenetic and statistical analyses illustrate a heterogeneous distribution of the AEA community, probably caused by the differential distribution of the terrestrial or estuarine AEA in the various sampling sites....

A Road Map to IndOOS-2: Better observations of the rapidly-warming Indian Ocean

M.; Vialard, J.; Roxy, M.k.; Li, J.; Andres, M.; Annamalai, H.; Feng, M.; Han, W.; Hood, R.; Lee, T.; Lengaigne, Matthieu; Lumpkin, R.; Masumoto, Y.; Mcphaden, M.j.; Ravichandran, M.; Shinoda, T.; Sloyan, B.m.; Strutton, P.g.; Subramanian, A.c.; Tozuka, T.; Ummenhofer, C.c.; Unnikrishnan, A.s.; Wiggert, J.; Yu, L.; Cheng, L.; Desbruyères, Damien; Parvathi, V.
The Indian Ocean Observing System (IndOOS), established in 2006, is a multi-national network of sustained oceanic measurements that underpin understanding and forecasting of weather and climate for the Indian Ocean region and beyond. Almost one-third of humanity indeed lives around the Indian Ocean, many in countries dependent on fisheries and rain-fed agriculture that are vulnerable to climate variability and extremes. The Indian Ocean alone has absorbed a quarter of the global oceanic heat uptake over the last two decades and the fate of this heat and its impact on future change is unknown. Climate models project accelerating sea level rise, more frequent extremes in monsoon rainfall, and decreasing oceanic productivity. In view of these new scientific...

Phylogenetic reassessment of the Chaetomium globosum species complex
Provedor de dados: 16
Autores: Wang, X.W.; Lombard , L.; Groenewald, J.Z.; Li, J.; Videira, S.I.R.; Samson, R.A.; Liu, X.Z.; Crous, P.W.
Chaetomium globosum, the type species of the genus, is ubiquitous, occurring on a wide variety of substrates, in air and in marine environments. This species is recognised as a cellulolytic and/or endophytic fungus. It is also known as a source of secondary metabolites with various biological activities, having great potential in the agricultural, medicinal and industrial fields. On the negative side, C. globosum has been reported as an air contaminant causing adverse health effects and as causal agent of human fungal infections. However, the taxonomic status of C. globosum is still poorly understood. The contemporary species concept for this fungus includes a broadly defined morphological diversity as well as a large number of synonymies with limited...

A taxonomic revision of Actinidiaceae of Vietnam
Provedor de dados: 16
Autores: Cuong, N.M.; Soejarto, D.D.; Li, J.
Taxonomic study of morphological variability using multivariate analysis, together with field studies and literature review clarified the status of a number of paired species of Saurauia and Actinidia of Vietnam and resolved their correct nomenclature: Saurauia tristyla is different from S. roxburghii; Saurauia petelotii is not a synonym of S. fasciculata but is a separate species; Actinidia tonkinensis is a synonym of A. latifolia; Actinidia indochinensis is a distinct species, not a variety of A. callosa; Saurauia dillenioides is a synonym of S. armata; and Saurauia griffithii var. annamica is a synonym of S. napaulensis. Four taxa of Actinidia are newly recorded for Vietnam. The results of this study will allow us to better understand the conservation...

Carbon flows through meiobenthic nematodes in the Westerschelde Estuary
Provedor de dados: 27
Autores: Li, J.; Vincx, M.; Herman, P.M.J.
A time dynamic model was used to estimate carbon flows through nematodes in an intertidal benthic ecosystem in the Westerschelde Estuary, The Netherlands. The model calibrated the nematode biomass observed from March 1991 to February 1992. The forcing functions of the model included meiobenthos biomass, macrobenthos biomass, bacterial density, chlorophyll-a concentration, and other abiotic data such as temperature and day length. We estimate that the nematode population had a low level of standing stock 249 mg C m(-2), but a high level of carbon flow. It consumed 98 mg C m(-2) d(-1) and produced 22 mg C m(-2) d(-1). Defecation was 73 mg C m(-2) d(-1). Losses in respiration, excretion and natural death were only 3 mg C m(-2) d(-1). The annual P/B was 32 for...

Vibrios associated with &lt;i&gt;Penaeus chinensis&lt;/i&gt; (Crustacea: Decapoda) larvae in Chinese shrimp hatcheries
Provedor de dados: 27
Autores: Vandenberghe, J.; Li, Y.; Verdonck, L.; Li, J.; Sorgeloos, P.; Xu, H.S.; Swings, J.
Bacteriological surveys were performed in 1995 and 1996 in three shrimp hatcheries located in the north of the People’s Republic of China. Samples were taken from routine productions of healthy &lt;i&gt;Penaeus chinensis&lt;/i&gt; larvae, their environment and from diseased larvae. A total of 186 isolates from the dominant bacterial flora was characterized by Biolog metabolic fingerprinting and identified by comparison to a database of 850 Vibrio type- and reference strains. Representative &lt;i&gt;Vibrio harveyi&lt;/i&gt; strains were further genotypically analyzed by AFLP fingerprinting of whole-genomes. An overwhelming predominance of &lt;i&gt;V. alginolyticus&lt;/i&gt; and &lt;i&gt;V. harveyi&lt;/i&gt; was observed in the larval developmental stages...

A model of nematode dynamics in the Westerschelde Estuary
Provedor de dados: 27
Autores: Li, J.; Vincx, M.; Herman, P.M.J.
We developed a time dynamic model to investigate the temporal dynamics of nematode community in the brackish zone of the Westerschelde Estuary. The biomass of four nematode feeding groups observed from March 1991 to February 1992 is used to calibrate the model. Using environmental data as the input, the model predicts the temporal modification and interrelation of four nematode feeding groups. Nematodes achieve a dominant position in the community because of their lower loss rate (in respiration, excretion and natural death). Predators which are deposit-feeding macrobenthos control the variations of dominant nematodes, such as omnivores and non-selective deposit feeders. Food availability causes modification only for rare nematodes such as epigrowth...
