The paper presents the preliminary results of investigations on the process of degeneration of some field phytocoenoses of winter cereals and flax in central Poland, occurring under the mechanical, chemical and biotic influence of anthropopression (Tables 1-6). It is endeavoured to present, on the basis of analysis of the relations between degeneration symptoms in phytocoenoses of some associations characteristic for this part of Poland and the effect of human activity on the agroecosystem, the mechanism and consequences of this degeneration and to establish the trends and extent of this process (Table 6). This might be useful in: - appropriate management and protection of the field environment, - rational organisation of agricultural production. At the same time it was undertaken to distinguish, define and separate the forms of degeneration within the phytosociologicol units analysed. This may be of importance for: – a correct evaluation of the interrelations between the field phytocoenosis and the habitat, – evaluation and cartographic presentation of the productive values of field habitats.

The work is a monograph of the regional vegetation accompanying crop plants in one of the most interesting mesoregions of central Poland. The standing phytosociological and ecological characteristic is given of 18 communities of segetal weeds against the natural conditions and changes in soil cultivation. On the basis of ecological and floristic analyses some regularities were established concerning: the structure and floristic composition of segetal communities, their dynamics distribution and spread, and the directions and extent of the contemporary transformations of these communities, due to the activity of man.

AbstractFollowing a brief discussion of the literature and intellectual history of Rome’s river port, this article presents preliminary results from a mechanized coring survey of the Forum Boarium valley. Conducted in 2015, this survey produced empirical evidence on prehistoric human activity Rome’s floodplain and acquired substantial data on the paleolandscape of the region, including the shifting position of the Tiber River and the discovery of lacustrine deposits in the valley. Additionally, consideration is given to the advantages and limitations posed by the natural landscape during the origins of settlement and early urban development at Rome.

Agriculture is one of the major anthropogenic contributors to climate changes and, at the same time, the one that can be seriously affected by the results of these changes, extreme weather conditions in particular. This paper presents the perception of climate change and its potential influence on the agricultural holdings of farmers, based on the survey conducted in łęczyński county (125 respondents). According to the survey, 39% of farmers believe that both human activity and natural environmental processes are equally responsible for climate changes. 37% of respondents claimed that climate changes are caused by human activity, while 24% of the surveyed farmers attributed those changes to natural environmental processes only. The vast majority of respondents is concerned that a possible consequence to the occurring changes may be increased costs of agricultural production (69%) and lowered standards of living (61%). The conducted survey proved high awareness of the need to protect the environment and soil among the farmers. 73% of them considers environmental regulations to have a positive impact on the agriculture and its future, but also to increase the work input of farmers and reduce their incomes.

Abstract Based on palaeobotanical analyses of organic deposits, as well as geomorphological and geological studies at four sites in various geomorphological locations in relation to tributaries of the Bzura River, the presence of traces of human activity, its intensiveness, and classification to cultural levels were analysed. A pattern of later and later settlement in areas remote from the axis of the Warsaw-Berlin streamway was observed along with the gradual introduction of settlement from river valley bottoms to watershed zones.

Segetal Communities

Characteristics of the changes in the agrophytocoenoses of the Bełchatów Industrial Region are presented in this paper. The observations were conducted on permanent areas during 1977-1983. Biological (phytosociological and bioindicatorial) methods were used. The dynamics of changes in weed communities in crop rotation were anlysed. Changes in the composition and structure of agrophytocoenoses belonging to 10 syntaxonomes and changes in their habitats were found. The causes and directions of these changes were established. These processes lead to the impoverishment of segetal flora and the formation of simpler formations which are less stable and less resistant to anthropopressure. On the basis of the results obtained in this study, an evaluation of the productivity of field habitats was made, agroecological regions were discerned and ways of forming and protecting agricultural production areas of the Bełchatów Industrial Region are given.

The paper contains preliminary results of mycological research conducted in the Białaczów forest reserve, situated at the Wzgórza Opoczyńskie Upland. There are only data on macromycetes at this area. The occurrence of 167 species of macrofungi has been documented on the background of variety of tree stand and habitats. In July 2011 a heavy wind storm destroyed the tree stand and devastated the reserve. Now the area is in course of natural renovation. The data presented in the paper could be used as comparative fungal material concerning qualitative and quantitative changes.

Abstract This research note presents evidence for the oldest Middle Pleistocene Eastern Saharan human activity from the area referred to as the Eastern Desert Atbara River (EDAR), Sudan, which is currently threatened by gold mining. Preliminary results of multifaceted analyses indicate the activity of Homo sapiens during MIS 5 as well as Homo erectus during MIS 7–11 or earlier.
