Potential use of remote sensing to assess effects of wave action on plant re-establishment

Evaluation of the potential for remote sensing to detect a relationship between wave action factors and plant re-establishment after a habitat enhancement at Lake Kissimmee, Florida. Using Geographic Information Systems (GIS) and remote sensing, wave action factors were found to be inversely related to the probability of plant re-establishment. However, correlation of wave action factors with areal coverage of aquatic plants based on field measurements, were unable to detect a significant relationship. Other factors aside from wave action, including littoral slope and the presence of offshore vegetation, may have influenced plant re-establishment in these sites. Remote sensing techniques may be useful to detect large changes in plants communities, however small changes in plant coverages may not be detectable using this technique

Repeating boundaries – repertoires of landscape regulations in southern Scandinavia in the Late Bronze Age and Pre-Roman Iron Age

Towards the end of the Late Bronze Age, linear boundaries such as enclosed farmsteads, field divisions, and pit zone alignments emerged and gradually permeated the landscapes of southern Scandinavia on multiple scales. This article suggests the concept of a ‘repertoire’ as a way of approaching this phenomenon. The repertoire consisted of different topological operations (e.g. plot definition, demarcation, and enclosure), constructed by different materials (e.g. fences, pit zones, and earthen banks) on different scales (e.g. farmstead, settlement, and landscape). Such linear boundaries were applied as technological solutions to the new social and economic problems that occurred at this time in prehistory. A number of chronological and regional preferences can be demonstrated within this repertoire, and during the Late Bronze Age and Pre-Roman Iron Age, a range of new applications and combinations were developed in a creative exploration of the repertoire of linear boundaries
