During 2015–2020, we carried out a series of field studies of zoogenic relief in the Oster River floodplain. In the process, the method of field route observations, polls, photography, morphological and morphometric analyses were actively used. Mathematical methods and computer technologies were used to process and summarize the obtained data. Based on the field research data, it was established that the natural conditions of the Oster River floodplain are favourable for the emergence of zoogenic relief forms. Zoogenic landforms are common here, and their size and location depend on the animal species which live in the area or constantly migrate through it. The influence of individual representatives of the animal world on the formation of the surface of the studied area is presented. It was shown that some of them simultaneously create both accumulative and negative forms of biogenic relief. Accumulative zoogenic landforms are represented in the Oster floodplain by individual small dams and beaver huts; muskrat huts; earthen anthills and anthills formed from dry grass and twigs; molehills; mice’s soil nano-strands; hamster mounds; pico-humps formed by worms and beetles. Among the negative landforms of zoogenic origin there are burrows and burrow nests; underground galleries of animals and insects; nano-basins of forest and field mice; livestock trails and wildlife migration trails; burrowing of wild pigs; footprints of various animals. Beavers, moles, wild boars and ants are found to cover the highest proportion of landform creation activity within the Oster River floodplain. It was also found that the size of most zoogenic landforms in the studied area have the rank of pico- and nano-relief. Relief microforms are much less common. The lifespan of zoogenic landforms can range from tens or even hundreds of years to several hours. It is discovered that fires significantly affect the landforms of zoogenic origin. As a result of the flames, many of the forms change their shape and size, and some even cease to exist.

Natural Settings

A constraint in the development of laboratory animal models of human disease conditions is their applicability to the natural environment in which a given animal species evolved. The range of behavioral patterns that can be carefully assessed and quantified in the laboratory is sometimes limited. Although field studies reflect behavioral responses in natural settings, they may also have methodological limitations. Laboratory techniques are not applicable to wild species since natural conditions cannot be brought into a laboratory in an inexpensive or reliable way. However, it is possible to create near-natural settings which may not fulfill all the criteria of the actual context of evolution, but which can be controlled by the experimenter. We recommend an integrative style of approach considering laboratory constraints and, at the same time, the ecological niche in which a given behavioral pattern evolved. This type of ethological assessment may be useful when carrying out toxicological studies on both wild and laboratory mammals.

The report shows the results of the Russian-Ethiopian historic and ethnographic expedition – a joint scientific project of two countries, successfully implemented in the early 1990s. Advanced results achieved by this expedition were much owed to participation of several leading Russian and Ethiopian scientific centers and universities – the Institute for African Studies, the Institute of Asian and African Countries at Lomonosov Moscow State University, Addis Ababa University and Institute for Ethiopian Studies, The Primakov Institute of World Economy and International Relations, and others. The participants of the expedition gathered and summarized a large body of data acquired during opinion polls, held in the course of the visits to a number of educational, medical, economic and manufacturing centers and organizations, including workshops, agricultural farms, banks, scientific centers. The collected scientific data has allowed, based on multi-factor analysis, to specify the nature of evolutionary processes in communal relations, efficiency of various aspects of federalism policy in a cosmopolitan country. Its value is reflected by applicability and sharp demand for a scientific view on one of the most troubled sides of social and political life of many African countries, and of the modern world. Based on the field research, a high number of articles and monographs have been prepared and published in the Russian Federation. They include “Report on Field Studies of Ethiopia Carried Out by Russian Historical, Ethnic, Sociological, Expedition, 1990–1992”, “Ethiopia: History, Culture and Ethnicity”, “Ethiopia: the Particular Features of Federalism”, “Drama in Modern Ethiopian Literature and Theatre”, “Mission in Ethiopia. African Policy of the USSR in the eyes of the Soviet Diplomat. 1956–1982”, two volumes of “Africa” encyclopedia and others.

Рассматривается состояние эндемичных байкальских амфипод в р. Енисей, приводятся результаты экспедиционных исследований. Отмечается факт многоразового увеличения количества амфипод в Енисее после зарегулирования плотиной Красноярской ГЭС. Данные гидробиологического мониторинга оформлены в виде геопространственной базы данных на геопортале, который предоставляет возможности визуализации результатов исследований в виде интерактивных тематических карт, прямого доступа к данным через картографические веб-сервисы из современных ГИС. The purpose. The purpose of the work is the theoretical and practical studies of the possibilities for using the geoinformation web-system modern technologies for improving the efficiency of hydrobiological monitoring, and design of software tools of data presentation and analysis for field research. Methods. The technologies for development of distributed information systems in multi-tier architecture, along with software interfaces and protocols, information exchange standards are considered. The possibilities for using of geoinformation and cartographic modelling methods for searching the relationship between the spatial distributions of Baikal amphipods in the Yenisei river with different environmental factors are investigated. Results. The technologies and related software are developed for the considered problem. The geospatial database is generated and filled with the results of own longterm hydrobiological field studies, it has become an integral part of the geoportal of ICM SB RAS, which was formed by the separate thematic section. The focus is on the results of extensive field studies of the Yenisei implemented in 2015 and 2016. As to database content, the information about the quantitative distribution of zoobenthos (animals inhabiting the ponds bottom), in particular endemic Baikal amphipods, in the area from Yenisei river headwaters to its delta was used. It was revealed that the amphipods — the endemics of the Baikal lake — spread far beyond its limits not only downward, but also upstream the Yenisei river. After the commissioning of the Krasnoyarsk hydroelectric power station, their share in the total zoobenthos biomass is increased by 10 times. Gmelinoides fasciatus crustacean is especially active; it has massively populated the area of the Upper Yenisei river below the Sayano-Shushensky reservoir. The density and the fraction of crustaceans in the zoobenthos in the area of the Angara — Podkamennaya Tunguska has increased over the last 15 years. Conclusions. Creation of a geospatial database alongside with the results of expeditionary research and the introduction of a GIS web-system for information-analytical support of hydrobiological monitoring significantly expands opportunities for the analysis and presentation of geodata, forms the basis for interdisciplinary research.

Abstract The results of the conducted pilot research indicated the basic local problems of the residents of Zabrze city. The purpose of the next research was to answer the question: how to improve the quality of life of residents in a city with significant air pollution. Activities aimed at this goal are inscribed in the idea of "smart city". The article presents the results of pilot measurements of air pollution with toxic gases in the Zabrze city in the Silesian agglomeration (Poland). Field studies at selected locations in the city concerned measurements of nitrogen dioxide, sulphur dioxide and carbon dioxide. The aim of these studies was to identify areas of the city with significant air pollution with toxic gases in order to plan further detailed research. Made measurements showed the appearance of the local problem of accumulation of pollutants in several areas of the city. The results obtained were compared with surveys conducted among residents of the Zabrze city. The aim of the survey was to examine the respondents' awareness of: the location of areas with noticeable air pollution and health problems resulting from air pollution in the place of residence. The article also presents a plan of possible actions for the city of Zabrze within the framework of the "smart city" idea to improve the quality of life of the local city community in conditions of increased emission of gas pollution in the city.

This chapter assesses survey and measurement execution problems in field research. Until recently, the vast majority of surveys in development field studies were done the old-fashioned way, on clipboards with pen and paper. The past five years have seen a huge shift toward electronic data collection using laptops, personal digital assistants (PDAs), or even smartphones. This has several advantages but also poses risks. It requires electricity to charge devices, often a challenge in rural areas of developing countries. Still, even as laptops, tablets, PDAs, and other technologies are incorporated, surveying remains a very human process. On the upside: surveyors can adapt, interpret, and problem-solve when necessary. On the downside: surveyors can adapt, interpret, and problem-solve whenever they want, which can substantially impact respondents' answers. Meanwhile, some researchers prefer to use measurement tools that capture data directly, without asking questions. The problem with measurement tools is that they do not always work as advertised.

A new approach to community-based nutritional surveillance has potential for improving programmes for growth promotion by focusing on the children at greatest risk and increasing the capacity for appropriate action. First, cross-sectional surveys can help to identify where malnutrition is distributed in the community so that high-risk groups can be targeted for intensive monitoring. Second, field studies can be conducted in parallel with general implementation to help define causal factors influencing local patterns of growth faltering and guide selection of an appropriate mix of interventions and methods to suit local conditions. This information can provide a better basis for training mothers, volunteers, and service personnel. Cultural, ecological, and economic constraints need to be identified as part of stimulating self-reliant community action. Demonstration of locally relevant and simplified procedures by a field research unit in each region should be linked with systematic extension to all parts of that region. These field research units should themselves be linked in a mutually supportive national and international network. Feedback of information from community-based surveillance can assist policy and administrative decisions for programme correction. These methods may provide our most direct means of introducing and measuring “adjustment with a human face.”

Purpose: To determine what types of EMS systems (public vs. private) are contributing to the peer reviewed field research in EMS and what type of research is being done by these agencies.Methods: A Medline literature search was conducted of all peer reviewed journals using the search terms: EMS, emergency medical services, EMT, paramedic, and ambulance. Studies published between 1976 and 1995 meeting these criteria were reviewed and classified as field or non-field studies. Studies were classified as field studies if they evaluated clinical outcomes or overall EMS system structure and performance. The type of EMS system in which the study was conducted was classified as: public (PB), private (PR), or a mixture of public and private agencies (PP). If the type of system was not evident in the paper, the primary author or EMS agency was contacted by phone. The primary affiliation of the first author was classified as being with: an educational institution, hospital, government agency, or EMS agency. Each study was also classified as being primarily clinical or evaluating EMS system structure. Review articles, editorials, and meta-analyses were excluded as were studies in which critical data elements could not be verified. Fischer's exact test was used for statistical analysis.Results: A total of 365 studies were evaluated with 66 non-field studies being excluded from analysis. 75 studies did not meet inclusionary criteria. This left 224 studies for analysis. PB systems accounted for 167 (74.5%) of field studies, with PP 44 (19.6%) and PR 13 (5.8%). Clinical studies were more commonly done by PB systems (72.5%) when compared to PR systems (38.5%), p = 0.02. System structure studies accounted for the majority of studies done by PR systems (61.5%). An affiliation with an educational institution such as a university occurred in 61.2% of the studies. The number of field studies done by PB systems has increased steadily over the last 10 years while field studies published by PR and PP systems has remained at a low level, with none published from 1992–1994.

Abstract Larval growth and survival of organisms are strongly influenced by abiotic and biotic factors, as demonstrated by experimental studies performed under controlled laboratory or semi-natural conditions. Even if they have many advantages, experiments cannot cover the full complexity of natural conditions and field studies are needed for a better understanding of how environmental variation determines growth and development rate. Fire salamander Salamandra salamandra females give birth to larvae in a variety of habitats, both epigean and subterranean. In caves, salamander larvae successfully grow and metamorphose, but their growth is more than three times longer than in epigean streams and factors determining these differences require investigation. We performed a field study to understand the factors related to the growth of fire salamander larvae in different environmental conditions, evaluating the relationship between environmental features and larval growth and differences between caves and epigean spring habitats. Both caves and epigean larvae successfully grew. Capture-mark-recapture allowed to individually track individuals along their whole development, and measure their performance. Growth rate was significantly affected by environmental variables: larvae grew faster in environments with abundant invertebrates and few conspecifics. Taking into account the effect of environmental variables, larval growth was significantly lower in caves. Food availability plays a different effect in the two environments. Larval growth was positively related to the availability of invertebrates in epigean sites only. The development rate of hypogeous populations of salamanders is slower because of multiple parameters, but biotic factors play a much stronger role than the abiotic ones.

Gene flow from imidazolinone (IMI)-resistant domestic sunflower to IMI-susceptible common sunflower and prairie sunflower was studied. Under greenhouse conditions, pollen from IMI-resistant domesticated sunflower was applied to flower heads of IMI-susceptible common and prairie sunflower. In addition, field studies were conducted in 2000 and 2001 near Manhattan, KS, to evaluate IMI-resistant gene flow from IMI-resistant domesticated sunflower to common and prairie sunflower under natural conditions. Common and prairie sunflower were planted in concentric circles at distances of 2.5, 5, 15, and 30 m around a densely planted IMI-resistant domesticated sunflower species. For both greenhouse and field studies, IMI-resistant gene flow was determined by treating the progeny of both wild species with 40 g ai ha−1of imazamox. Greenhouse crosses made by hand showed that 94% of common sunflower and 79% of prairie sunflower were resistant or moderately resistant. The resistant plants were allowed to grow in the greenhouse and were backcrossed with the corresponding susceptible wild parents. Progeny of the backcross showed a 1:1 ratio of resistant to susceptible plants. In the field, gene flow was detected up to 30 m from the pollen source for both species, and it decreased as distance from the pollen source increased. In 2000, 11 to 22% of the progeny were resistant at 2.5 m from the pollen source and 0.3 to 5% were resistant at 30 m. In 2001, the number of resistant progeny did not exceed 7 and 2% at 2.5 and 30 m from the pollen source, respectively. The results of this study showed that IMI-resistant domesticated sunflower outcrosses with common and prairie sunflower over distances typically encountered near production fields. Also, backcrosses of resistant hybrids with wild parents are successful, further increasing the potential for the spread of IMI-resistant feral sunflowers.

Applications of video in fisheries research range from simple biodiversity surveys to three-dimensional (3D) measurement of complex swimming, schooling, feeding, and territorial behaviors. However, researchers lack a transparently developed, easy-to-use, general purpose tool for 3D video measurement and event logging. Thus, we developed a new measurement system, with freely available, user-friendly software, easily obtained hardware, and flexible underlying mathematical methods capable of high precision and accuracy. The software, VidSync, allows users to efficiently record, organize, and navigate complex 2D or 3D measurements of fish and their physical habitats. Laboratory tests showed submillimetre accuracy in length measurements of 50.8 mm targets at close range, with increasing errors (mostly <1%) at longer range and for longer targets. A field test on juvenile Chinook salmon (Oncorhynchus tshawytscha) feeding behavior in Alaska streams found that individuals within aggregations avoided the immediate proximity of their competitors, out to a distance of 1.0 to 2.9 body lengths. This system makes 3D video measurement a practical tool for laboratory and field studies of aquatic or terrestrial animal behavior and ecology.
