Abstract. The aim of the present study was to compare preservation, staining and preparation techniques assess influence different sample treatments analyses on accuracy benthic foraminiferal assemblage data from NE Atlantic shelf seas. Replicate surface samples SE North Sea were preserved with ethanol–rose Bengal or formalin, some stained after processing, foraminifera concentrated by flotation. Coloration living specimens between treated an solution those washing. In latter case, only last...
The bright colouration of the cytoplasm in intertidal rotaliid foraminifera and their particle-gathering activity reliably reveals live specimens fresh samples, without any fixatives or dyes applied. Using this approach, we demonstrate that representatives three species, all belonging to genus Elphidium, were common on mud sand beaches. Two E. excavatum clavatum albiumbilicatum, lived close freshwater outflows, whereas williamsoni occupied beaches bathed by waters with normal salinity...
Symbiotic microorganisms may provide their hosts with abilities critical to occupation of microhabitats. Gut (intestinal) bacterial communities aid animals digest substrates that are either innutritious or toxic, as well support development and physiology. The role microbial associated sibling species in the hosts’ adaptation remains largely unexplored. In this study, we examined composition plasticity bacteriomes two intertidal gastropod species, Littorina fabalis L. obtusata, which...
The article deals with the choice of cutterheads for Geokhod in early development stages. Early stages are characterized by lack quantitative characteristics, such as cutting forces, weight, feed etc. In this case, is made on accordance requirements them. Under conditions were determined most appropriate method multi-criteria analysis – “ELECTRE III”. results use established fully meet cutter heads: a rotary, drum, and head fixed heads.
Представлены результаты исследования некоторых аспектов биологии домового и полевого воробьев в условиях города Сыктывкара. В период с января по июнь 2021 года на территории (S = 11,05 км2) результате подсчета абсолютной численности зарегистрировано 1127 особей воробья плотностью населения 101,9 ос./км2 130 11,5 ос./км2. Характер распределения птиц неравномерный. Домовый воробей преимущественно заселяет окраины города, что обусловлено сочетанием доступных источников корма, большим числом...
Glaciers in the fjords of Svalbard have been receding over last decades. Tempelfjorden, a typical glaciated fjord West Spitsbergen (78°24′06″ N, 17°02′30″ E), has sampled summer 1995 and 2001–2007 for modern benthic foraminifera. We normalized abundances unified taxonomy all these published unpublished data sets then compiled record foraminiferal assemblages changing years into comprehensive database. The includes on living dead species surface sediments (0–2 cm) downcore foraminifera (only...
The aim of R/V Alkor cruise AL438 was to investigate the assemblage composition, population density and distribution Recent benthic foraminifera in Elbe estuary southern North Sea. We focused on an assessment present state of the ecosystems a comparison with data from former decades. Our work resumed investigations Geologisch-Palaontologisches Institut Kiel University the Federal Hydrographic Office 1960s till 1980s, as well topical studies the west Helgoland. revisited same stations...
Abstract. Experimental data of pressure variations on the Earth’s surface during passage an atmospheric front recorded a network 4 microbarographs in Moscow region is used. Applying this experimental data, empirical approximations field oscillations are suggested. The obtained approximating functions used as lower boundary condition for simulating vertical propagation acoustic-gravity waves from source troposphere. Estimates amplitude temperature disturbances upper atmosphere caused by...
