This analysis involves the identification and counting of these species which requires broad experience and knowledge. The automatization of these tasks is highly desirable as it would release the experts from tedious work, eliminate subjective factors, and improve repeatability. Thus, in this preliminary work, we propose to advance towards an automatic methodology for phytoplankton analysis in digital images of water samples acquired using regular microscopes. In particular, we propose a novel and fully automatic method to detect and segment the existent phytoplankton specimens in these images using classical computer vision algorithms. The proposed method is able to correctly detect sparse colonies as single phytoplankton candidates, thanks to a novel fusion algorithm, and is able to differentiate phytoplankton specimens from other image objects in the microscope samples (like minerals, bubbles or detritus) using a machine learning based approach that exploits texture and colour features.

In order to evaluate the applicability of an in situ FluoroProbe instrument, chlorophyll a (chl a) measured with this device was compared to chl a measured by a fluorometer and to algal densities and biovolumes determined by direct counts. Monthly surveys were conducted in 3 types of aquaculture ponds (tilapia, milk fish, and common orient clam) from October 2011 through April 2012 in the Cigu region of Tainan City, Taiwan. Results showed that green algae were the predominant phyto- plankton group, followed by cyanobacteria, euglenoids, and diatoms. The 3 types of aquaculture −3 ponds had wide ranges of chl a, pH, salinity, turbidity, PO4 -P, and suspended solids.

We investigated methodological (abundancemicroscopy vs. abundanceHTS, bio- massmicroscopy vs. abundanceHTS), habitat (littoral, pelagic, deep hypolimnion), and year (2014 vs. 2017) differences for phytoplankton communities of Lake Tovel (Italy) using ANOVA. Specifically, we tested the hypothesis that depending on comparing abundancemicroscopy or biomassmicroscopy to abundanceHTS different ef- fects would be indicated; we called this the metric effect. Furthermore, using samples from 2014 to 2017, we investigated environment–community relation- ships by a redundancy analysis based on abundancemicroscopy, biomassmicroscopy, and abundanceHTS, and compared the results. 3. Approximately 9 times more operational taxonomic units were reported with HTS (n2014 = 819, n2017 = 891) than algal taxa with microscopy (n2014 = 90, n2017 = 109) in 2014 and 2017. While microscopically assessed algal taxa were evenly distrib- uted among phyla, the vast majority of operational taxonomic units were attrib- uted to Chrysophyta (2014 = 54%, 2017 = 62%) and Bacillariophyta (2014 = 19%, 2017 = 17%).

  • A Review of Phytoplankton Ecology in Freshwater Rivers and Lakes of India
    IJSTE - International Journal of Science Technology & Engineering | Volume 3 | Issue 06 | December 2016 ISSN (online): 2349-784X A Review of Phytoplankton Ecology in Freshwater Rivers and Lakes of India Smruti Sohani Associate Professor Department of Botany Dr. APJ Abdul Kalam, University, Indore, India Abstract Water resource is an essential ingredient for human survival. The availability of safe drinking water is important for proper growth of human being. This is a comprehensive review of phytoplankton ecology in freshwater lakes of India. A review study was undertaken for the better understanding of the phytoplankton distribution. In broad terms, authors discussed the relations of phytoplankton with factors like lake temperature, sunlight exposure period, sunlight penetration, water pH, wind, transparency, seasonal variations, water characteristics, nutrient enrichment and prey-predator relation in the lakes of India. From the results, authors noticed that each lake habitat is different from other lake habitat. Finally, authors concluded that phytoplankton ecology is an indicator for the evaluation of impacts of influencing factors. These factors provide a suitable management plan for lakes. Phytoplankton ecology provides a ground for monitoring and assessing the strategies of the fresh water lake management. Keywords: Phytoplankton ecology, River, Lake, Seasonal fluctuation, Phytoplankton distribution ________________________________________________________________________________________________________ I. INTRODUCTION About four thousand million years ago, life initiated in an aquatic environment. Today, most of the taxonomic phyla dwell in an aquatic environment. In an aquatic environment, phytoplankton is most ubiquitous, unicellular and microscopic life form. Phytoplankton collectively accounted about half of the earth’s primary producers Manisha D.

We report fundamental chemical characteristics that may exert contrasting selective differences in size distributions of marine and freshwater diatoms, pressures on phytoplankton cell size. Although both nitrogen with marine diatoms significantly larger than freshwater species. (N) and phosphorus (P) can limit different species at different An evolutionary game theoretical model with empirical allometries times and locations, overall, N is thought to be more often of growth and nutrient uptake shows that these differences can be limiting than P in marine systems, with the reverse in freshwaters explained by nitrogen versus phosphorus limitation, nutrient fluc- (9). The mixed layer depth (MLD) is typically greater in marine tuations and mixed layer depth differences. Constant and pulsed systems than in freshwaters (10–12), thus affecting diatom phosphorus supply select for small sizes, as does constant nitrogen persistence in the water column.

WHAT IS FRESH WATER? freshwater algae fall into a large, but ecologically meaningful collection of environments: all habitats that The study of freshwater algae is really the study of are at least slightly wet, other than oceans and estuaries. organisms from many diverse habitats, some of which One reason for such a broad scope is that inland saline are not entirely “fresh.” Although the oceans are clear- lakes, snow and ice, damp soils, and wetlands are ly saline (Ϸ 35 g salts L–1) and most lakes are relatively studied by phycologists and ecologists who also exam- dilute (world average < 0.1 g L–1; Wetzel, 1983a), there ine more traditional freshwater environments.
