Global warming is a serious world problem where earth’s temperature has been reported to increase over the years; aquatic ecosystems are also not exceptions. But, effects of this phenomenon on well understood. This study aims understand influence surface population density Limnothrissa miodon in Lake Kariba. We constructed mathematical model dynamics with nutrients, phytoplankton, zooplankton, ...

Coastal waters are dynamic because of anthropogenic activities that contribute nutrients and contaminants. These changes have the potential to alter patterns primary production thus pelagic food webs. Here, we investigated spatial variation phytoplankton community its response changing environmental variables at 84 stations along five coastal districts Tamil Nadu (TN). During present study, 85 ...

Structural changes in phytoplankton communities have large influence on marine elemental cycling, food web dynamics and carbon export. Here we used data from two field expeditions, performed spring fall, over a coast-offshore gradient to investigate structure the Southwestern Tropical Atlantic (SWTA). Results revealed predominant role of thermohaline as main driver regardless season. In thermoc...

In the intense mucilage formation observed in Sea of Marmara 2021, Phaeocystis pouchetii (Prymnesiophyceae) together with Skeletonema costatum, Cylindrotheca closterium, Thalassiosira rotula (Bacillariophyceae), and Gonyaulax fragilis (Dinophyceae) were detected foamy surface layer, Chrysoreinhardia giraudii Nematochrysopsis marina (Chrysophyceae), which are known to produce filamentous benthic...

An investigation was carried out to comprehend the altitudinal variation of phytoplankton and their distribution pattern in River Teesta. Phytoplankton were recorded at two different altitude levels river. A total 35 genera with dominated by diatoms. The differences reflected comparatively high genus richness high-altitude region. Seasonal spectrum maximum during post-monsoon (7.67 ± 13.42 ul−1...

La estructura taxonómica de la comunidad fitoplanctónica se encuentra influenciada por múltiples factores, en su mayoría integrados aspectos funcionales y del metabolismo ecosistema. Con el objetivo evaluar variación fitoplancton lagos andinos sobre un amplio espectro condiciones, realizó estudio 12 Cordillera Oriental colombiana agrupados diferentes rangos altitudinales (alta montaña tropical,...

Utilization of seluang fish (Rasbora sp.) for food and collection by the community as decorative to serve a source income. The objective research on identification plankton in digestion from Musi river downstream is determine type ingested fish, phytoplankton or zooplankton, which are fish's natural source. Prior domestication, variations can be exploited cultivation efforts knowledge. study wa...

Kakap River Estuary plays an essential role in the life organisms, but it is vulnerable to environmental changes and pollution caused by human activities. This study aims assess presence of plankton species, their abundance diversity as aquatic ecological bio-indicators Estuary. Plankton water samples were taken for three months, with a frequency one sample per month, viz. March, April June 202...

This study was carried out from December 2018 to November 2019 examine the distribution and abundance of harmful algal species (HAS) in central Bonny estuary. Seven sampling stations were established with ArcGIS tool. Microalgae sampled 20 mm mesh plankton net. Nutrients analyzed laboratory using APHA 4500 Method, while physicochemical characteristics determined situ. Results revealed that envi...

Coastal waters of Bojonegara in Banten Bay has a lot pressure from the surrounding environment, including industry and sand mining. The high intensity limited space encourage reclamation coastal areas which can trigger changes water quality. Research was conducted October to December 2019, aims analyze phytoplankton biodiversity pollution bioindicator waters. obtained through filtering 50 liter...
