Ecological systems are exposed and are influenced by various natural and anthropogenic disturbances. They produce various effects and states seeking response symmetry to a state of global phase coherence or stability and balance of their food webs. This research project addresses the development of a computational methodology for modeling plankton food webs. The use of algorithms to establish c...

“Big data” are becoming common in biological oceanography with the advent of sampling technologies that can generate multiple, high-frequency data streams. Given the need for “big” data in ocean health assessments and ecosystem management, identifying and implementing robust, and efficient processing approaches is a challenge for marine scientists. Using a large plankton imagery data set, we pr...

The mangrove ecosystem is one of the ecosystems in estuary area that unique and very sensitive to environmental changes. large number aquaculture businesses around Cemare Hamlet, West Lombok Regency have resulted many areas being converted into pond cultivation locations. This will an impact on life such as plankton. study aims determine abundance plankton species ??Dusun Cemare, Sheet Selatan ...

Using the field sampling data obtained in November 2012, the aquatic ecosystem health of river network in Hangzhou Bay New District in Ningbo was assessed with Plankton Index of Biology Integrity (P-IBI). In these samples, 125 species of phytoplankton and 19 species of zooplankton were identified and the dominant phytoplankton species of each sampling sites were almost pollution indicator speci...

Uptake of ["C] glycine by various size fractions of natural plankton communities was measured to determine if phytoplankton can compete effectively with other members of the plankton community for the free amino acids in seawater. The simultaneous occurrence of glycine uptake, plant pigments, and photosynthetic activity in the same size fractions, as well as autoradiography of the plankton samp...

The thesis analyses effects of pollutants on natural plankton communities on the basis of three independent mesocosm experiments and a series of laboratory experiments performed in Denmark and Greenland. The work focus on integrating functional and structural measures of community responses to reveal indirect effects and co-effects with the abiotic environment on three trophic levels, namely ba...

Most studies of biodiversity focus on either macroscopic or microbial communities, with little or no simultaneous study of eukaryotes and prokaryotes. We tested whether a universal metabarcoding approach could be used to study the total diversity and temporal dynamics of aquatic picoto mesoplankton communities in a shallow temperate lake. The approach revealed significant changes in the relativ...
