Phosphorus forms in the sediment of seagrass meadows affected mainly by fungi rather than bacteria: a preliminary study based on 31P-NMR and high-throughput sequencing

20 listopada 2020 Muqiu Zhao and 4 more 0

Microorganisms play an important role in the circulation of phosphorus (P) in the sediment of coastal wetland ecosystems. In this study, solution <sup>31</sup>P nuclear magnetic resonance (NMR) was used to determine different forms of P […]

Seasonal and annual variability in chlorophyll-a in the shelf region of the Northern Bay of Bengal using MODIS-Aqua data

20 listopada 2020 Muhammad Abdur Rouf and 2 more 0

Chlorophyll-a (Chl-a) concentration is an important issue in ocean ecosystem management and research. This study investigates seasonal and annual variability in Chl-a and its relationship with sea surface temperature (SST) and river discharge in the […]

First recorded bloom of Akashiwo sanguinea (Dinophyceae) from the Cochin backwaters, a tropical estuarine system along the South Eastern Arabian Sea

20 listopada 2020 Twinkle Sathish and 4 more 0

Akashiwo sanguinea, a cosmopolitan red tide-forming dinoflagellate, is reported for the first time as a bloom from the Cochin estuary along the South Eastern Arabian Sea. Monthly sampling showed the continuous presence of A. sanguinea […]

Growth parameters of invasive gibel carp Carassius gibelio (Bloch, 1782) in Lake Marmara (Turkey)

20 listopada 2020 Ali Ilhan and 2 more 0

The objective of this study was to determine growth parameters, such as age–length and length–weight relationships, as well as condition factors and sex ratio, of the Carassius gibelio (Bloch, 1782) population in Lake Marmara (western […]

Spatio-temporal variation in the distribution and abundance of marine cladocerans in relation to environmental factors in a productive lagoon (Güllük Bay, SW Aegean Sea, Turkey)

20 listopada 2020 Nurçin Killi 0

In order to understand the effects of some physical (temperature and salinity) and chemical (dissolved oxygen, nitrate and chlorophyll a) factors on the abundance and distribution of cladoceran species, zooplankton samples were seasonally collected between […]

Influence of land development on the ecological status of small water bodies

20 listopada 2020 Anna Dudzińska and 2 more 0

Small water bodies play a specific role in the landscape, as they increase the mosaic pattern of a given area, retain water and affect hydrological regime in adjacent soils. These water bodies are the most […]

Response of the rotifer community to human-induced changes in the trophic state of a reservoir

20 listopada 2020 Seong-Ki Kim and 3 more 0

Human disturbance and nutrient runoff lead to water pollution, particularly in downstream waters and reservoirs. We hypothesized that increased human activity in summer would affect the trophic state of downstream reservoirs, affecting the interannual species […]

Preliminary results on the ovarian histology of rabbitfish Siganus rivulatus (Forsskal, 1775) in the southern Aegean Sea, Turkey

9 września 2020 Serhat Engin and 3 more 0

The study aimed to determine the annual reproductive cycle of Siganus rivulatus  females based on monthly variation of the gonadosomatic index (GSI) and histological changes in gonads. A total of 240 fish samples were collected […]
