| The present study compares fish species composition, dominance, and size-structure patterns at an open sand beach area (32°15'S, 52°46'W) in Mirim Lake, RS, Brazil, estimated from samples collected with two distinct beach seine nets. The BS-9m net is 9 m long and 1.5 m high, and is made with a 5 mm multifilament mesh on its central portion and 12 mm on the side wings. The BS-30m net is 30 m long and 1.8 m high, with a 12 mm monofilament nylon mesh all over the net, except for a 30 cm strip made with a 12 mm multifilament mesh on the lower portion. Thirty hauls were performed with both nets resulting in a total of 849 fish captured, comprising 34 species. BS-9m was selective for individuals smaller than 60 mm TL and BS-30m for individuals larger than 60 mm... |

| There are few studies on the zooplankton from the northwestern region of São Paulo State, Brazil, compared to other regions of the State. Cladocerans are a very representative zooplankton group with high species diversity. Most of this diversity can be found at littoral zones of lakes and reservoirs, especially those occupied by macrophytes. This study was part of a thematic project FAPESP/BIOTA Program - The Virtual Institute of Biodiversity (www.biotasp.org.br), and its aim is to catalogue and analyze the distribution of cladoceran species (Crustacea, Anomopoda and Ctenopoda) in pelagic and littoral zones from small reservoirs in the northwest of the São Paulo State, in dry and rainy seasons. Zooplankton samplings were carried out in littoral and pelagic... |

| В прибрежных наносах линии уреза северного побережья Севастопольской бухты впервые определено содержание белков, аминокислот и углеводов. Установлено преобладание количества белков над углеводами, в то время как в море в целом преобладают углеводные соединения. Если в целом в Севастопольской бухте наблюдаются сезонные колебания концентрации органических веществ, то в условиях наносов, постоянно омывающихся морской водой, сезонная динамика не наблюдается. Отношение концентрации углеводов к белку в наносах составляет десятые и сотые доли, что в десятки раз ниже, чем в поверхностном слое грунтов как открытого моря, так и бухт. Средняя концентрация белков и углеводов в наносах выше, чем в грунтах того же механического состава. |
