Freshwater green algal biofouling of boats in the Kabul River, Pakistan
Oceanological and Hydrobiological Studies - Tập 43 - Trang 329-336 - 2015
Izaz Khuram, Nadeem Ahmad, Samin Jan, Sophia Barinova
Freshwater green algal biofouling of boats refers to the accrual of freshwater green algae on boats immersed in water. The current research focused on the morphological characteristics of the isolates, species ecology, and the physicochemical properties of the water at the sampling sites. Two localities, Haji Zai and Sardaryab, were sampled at the Kabul River in the district of Charsadda, Pakistan...... hiện toàn bộ
Identification of water quality and benthos characteristics in Daya Bay, China, from 2001 to 2004
Oceanological and Hydrobiological Studies - Tập 40 - Trang 82-95 - 2011
You-Shao Wang, Cui-Ci Sun, Zhi-Ping Lou, Haili Wang, B. Greg Mitchell, Mei-Lin Wu, Zong-Xun Sun
Physicochemical and benthos data were collected from 12 marine monitoring stations in Daya Bay, during 2001-2004. 12 stations in Daya Bay could be grouped into three clusters: cluster I consisted of stations in the southern part of Daya Bay (stations S1, S2 and S6); cluster II consisted of stations in the cage culture areas (stations S3, S4, S5 and S8); cluster III consisted of stations in the sou...... hiện toàn bộ
Tích lũy đồng thời của anatoxin-a và microcystins ở ba loài cá bản địa sống trong các hồ bị ảnh hưởng bởi sự nở hoa tảo lam Dịch bởi AI
Oceanological and Hydrobiological Studies - Tập 41 Số 4 - Trang 53-65 - 2012
Barbara Pawlik‐Skowrońska, Magdalena Toporowska, Jacek Rechulicz
Tóm tắt Một nghiên cứu trong bốn năm được thực hiện tại một hồ nước có hiện tượng nở hoa tảo kéo dài do Planktothrix agardhii (Oscillatoriales) và Anabaena lemmermanii, Anabaena flos-aquae, Anabaena spp. và Aphanizomenon issatchenkoi (Nostocales) gây ra đã chỉ ra rằng cá sinh sống dưới hồ bị đe dọa bởi sự tiếp xúc đồng thời với microcystins (MCs) nội...... hiện toàn bộ
Four small-celled Planothidium species from Central Europe proposed as new to science
Oceanological and Hydrobiological Studies - Tập 43 - Trang 346-359 - 2015
Małgorzata Bąk, Horst Lange-Bertalot
Four small-celled taxa are presented and described — Planothidium werumianum, P. pumilum, P. rhombiculum and P. rostratoholarcticum. Planothidium werumianum, P. pumilum and P. rhombiculum are proposed as new to science and P. rostratoholarcticum as a new name for Achnanthes lanceolata var. rostrata Hustedt 1911. The latter, coming from Germany, is transferred to Planothidium in the species rank. T...... hiện toàn bộ
The story of one clam. Probably the oldest location of the Chinese pond mussel Sinanodonta woodiana (Lea, 1834) (Bivalvia, Unionidae) in Poland
Oceanological and Hydrobiological Studies - Tập 41 - Trang 41-45 - 2011
Maria Urbańska, Andrzej Łakomy, Wojciech Andrzejewski, Jan Mazurkiewicz
The discovery of a shell of the Chinese pond mussel in 1998 and further confirmation of this species indicate that a reservoir with natural thermal conditions is the oldest species location in Poland. Growth increments of an archival shell do not fall within the ranges obtained by this species in Konin lakes. They are, however, close to population ranges from Hungary. In contrast to other specimen...... hiện toàn bộ
Species density obtained for fish sampled with three seine nets hauled individually towards a stop net or a bank
Oceanological and Hydrobiological Studies - - 2013
T. Penczak
Abstract Researchers continuously search for adequate and inexpensive fish sampling methods and, as such, it is worth remembering the quantitative seine method with three identical nets hauled individually towards a stop net or a bank. A sample obtained by three nets is the absolute minimum for any accurate estimate employing a removal technique, and...... hiện toàn bộ
Effects of coastal upwelling on picophytoplankton distribution off the coast of Zhanjiang in South China Sea
Oceanological and Hydrobiological Studies - Tập 43 - Trang 283-291 - 2014
Mei-Lin Wu, You-Shao Wang, Dong-Xiao Wang, Jun-De Dong
Coastal upwelling occurred along the west coast of Guangdong in the northern South China Sea during the summer of 2006. The effects of upwelling on the vertical and horizontal distributions of Prochlorococcus and Synechococcus were investigated. A distinct vertical temperature difference between the surface water and water at a depth of 30 m was observed in the coastal upwelling region. There was ...... hiện toàn bộ
The structure of psammic rotifer communities in two boreal lakes with different trophic conditions: Lake Võrtsjärv and Lake Saadjärv (Estonia)
Oceanological and Hydrobiological Studies - Tập 43 Số 1 - Trang 49-55 - 2014
Külli Lokko, Taavi Virro
Abstract Psammon communities are still poorly studied worldwide. The aim of the present study was to establish the structure of psammic rotifer communities including their diversity and quantitative parameters. A total of 41 rotifer taxa were found in hydro-, hygro-, and euarenal zones of eutrophic Lake Võrtsjärv and mesotrophic Lake Saadjärv during ...... hiện toàn bộ
Inventory of the taxonomical composition of the plankton ciliates in the Curonian Lagoon (SE Baltic Sea)
Oceanological and Hydrobiological Studies - Tập 40 - Trang 86-95 - 2011
Evelina Grinienė, Stasė Mažeikaitė, Zita Rasuolė Gasiūnaitė
Species composition of plankton ciliates was studied in the Curonian Lagoon in 2007–2008 and compared to long term investigations dating back to the 1980th. In total, 152 taxa were identified at the level of species or genera. More species (76 species/higher taxa) was found in the estuarine part of the Lagoon due to temporally unstable salinity and the presence of both freshwater and brackish/mari...... hiện toàn bộ
Comparison of gastrotrich fauna on elodeids and in bottom sediments of lakes of different trophic status (the region Polesie Lubelskie, Eastern Poland)
Oceanological and Hydrobiological Studies - Tập 40 Số 2 - Trang 13-21 - 2011
Teresa Nesteruk
Abstract Species diversity of gastrotrich communities on elodeids and in bottom sediments of lakes of different trophic status was compared. Thirty-eight species of Gastrotricha (34 in bottom sediment and 21 on elodeids) were found, which belong to the only family of Chaetonotidae Zelinka, 1889. Species diversity of both habitats was reflected in the...... hiện toàn bộ
