Effects of flow restoration on mussel growth in a Wild and Scenic North American RiverSpringer Science and Business Media LLC - Tập 9 - Trang 1-11 - 2013
Brandon J Sansom, Daniel J Hornbach, Mark C Hove, Jason S Kilgore
Freshwater mussels remain among the most imperiled species in North America due primarily to habitat loss or degradation. Understanding how mussels respond to habitat changes can improve conservation efforts. Mussels deposit rings in their shell in which age and growth information can be read, and thus used to evaluate how mussels respond to changes in habitat. However, discrepancies between metho...... hiện toàn bộ
Community solar salt production in Goa, IndiaSpringer Science and Business Media LLC - Tập 8 - Trang 1-8 - 2012
Kabilan Mani, Bhakti B Salgaonkar, Deepthi Das, Judith M Bragança
Traditional salt farming in Goa, India has been practised for the past 1,500 years by a few communities. Goa’s riverine estuaries, easy access to sea water and favourable climatic conditions makes salt production attractive during summer. Salt produced through this natural evaporation process also played an important role in the economy of Goa even during the Portuguese rule as salt was the chief ...... hiện toàn bộ
Hematodinium sp. and its bacteria-like endosymbiont in European brown shrimp (Crangon crangon)Springer Science and Business Media LLC - Tập 8 - Trang 1-10 - 2012
Grant D Stentiford, Kelly S Bateman, Hamish J Small, Michelle Pond, Anette Ungfors
Parasitic dinoflagellates of the genus Hematodinium are significant pathogens affecting the global decapod crustacean fishery. Despite this, considerable knowledge gaps exist regarding the life history of the pathogen in vivo, and the role of free living life stages in transmission to naïve hosts. In this study, we describe a novel disease in European brown shrimp (Crangon crangon) caused by infec...... hiện toàn bộ
Molecular analysis of bacterial diversity in mudflats along the salinity gradient of an acidified tropical Bornean estuary (South East Asia)Springer Science and Business Media LLC - Tập 10 - Trang 1-13 - 2014

The Brunei River and Bay estuarine system (BES) in the northwest of Borneo is acidic and highly turbid. The system supports extensive intertidal mudflats and presents a potentially steep salinity and pH gradient along its length (45 km). Temporal variation in physical parameters is observed diurnally due to seawater flux during tidal forcing, and stochastically due to elevated freshwater inflow af...... hiện toàn bộ
Analysis of β-N-methylamino-L-alanine (BMAA) in spirulina-containing supplements by liquid chromatography-tandem mass spectrometrySpringer Science and Business Media LLC - Tập 10 - Trang 1-7 - 2014
Pearse McCarron, Alan C Logan, Sabrina D Giddings, Michael A Quilliam
Over the last decade the amino acid beta-N-methylamino-L-alanine (BMAA) has come under intense scrutiny. International laboratory and epidemiological research continues to support the hypothesis that environmental exposure to BMAA (e.g., through dietary practices, water supply) can promote the risk of various neurodegenerative diseases. A wide variety of cyanobacteria spp. have previously been rep...... hiện toàn bộ
Bacterial diversity of the rock-water interface in an East Antarctic freshwater ecosystem, Lake Tawani(P)†Springer Science and Business Media LLC - Tập 9 - Trang 1-10 - 2013

Schirmacher Oasis is one of the few ice-free plateaus in East Antarctica that maintains a unique distribution of over 120 microbial-rich, dynamic freshwater lakes, most of which are unexplored. In this study, we describe the bacterial diversity of the rock-water interface in Lake Tawani(P) using culture-independent Bacterial Tag Encoded FLX Amplicon Pyrosequencing (bTEFAP), clone library construct...... hiện toàn bộ
Kinetics of arsenite removal by halobacteria from a highland Andean Chilean SalarSpringer Science and Business Media LLC - Tập 9 - Trang 1-11 - 2013

The purpose of this study was to identify arsenite-oxidizing halobacteria in samples obtained from Salar de Punta Negra, II Region of Chile. Seven bacterial isolates, numbered as isolates I to VII, grown in a culture medium with 100 ppm as NaAsO2 (As (III)) were tested. Bacterial growth kinetics and the percent of arsenite removal (PAR) were performed simultaneously with the detection of an arseni...... hiện toàn bộ
