His interest is to study the organization of landscapes and how organisms perceive the surrounding complexity. Recently AF has incorporated the principles of biosemiotic into the ecological domain developing the eco-field hypothesis and elaborated the General Theory of Resources. During the last ten years, he has worked on the fundaments of ecoacoustics. He published more than 290 reports, articles and books on zoology, eco-ethology, bird community ecology, landscape ecology, landscape changes, rural landscape modification, eco-semiotics, code biology, and ecoacoustics.
Principles and methods of landscape ecology are intensively used to model and to manage disturbed landscapes and menaced pristine areas as well. Students and professionals can find a new version of "Principles and Methods in Landscape Ecology" firstly published in 1998 by Chapman & Hall (London).
The Landscape and Seascape Ecology Team are ecologists, earth and water scientists, and geographers working to elucidate the linkages between habitat and anadromous fish that spawn in California. Our approach to this uses principles and methods from fish and stream ecology and biology, landscape, ecosystem, community, and population ecology with climatology, oceanography, hydrology, and geomorphology. One aspect of our research is documentation of spatial and temporal patterns in biota and the environment. We use field surveys, remote sensing, GIS, field experiments, tagging, capture-recapture studies, and statistical and process-based modeling in various combinations. Our work seeks to explain how and why fish populations have declined and recovered in the past, identify resilient and sensitive habitats, and guide habitat restoration and species recovery efforts in the future.
Today, theory and application of landscape ecology continues to develop through a need for innovative applications in a changing landscape and environment. Landscape ecology relies on advanced technologies such as remote sensing, GIS, and models. There has been associated development of powerful quantitative methods to examine the interactions of patterns and processes.[5] An example would be determining the amount of carbon present in the soil based on landform over a landscape, derived from GIS maps, vegetation types, and rainfall data for a region. Remote sensing work has been used to extend landscape ecology to the field of predictive vegetation mapping, for instance by Janet Franklin.
Some research programmes of landscape ecology theory, namely those standing in the European tradition, may be slightly outside of the "classical and preferred domain of scientific disciplines" because of the large, heterogeneous areas of study. However, general ecology theory is central to landscape ecology theory in many aspects. Landscape ecology consists of four main principles: the development and dynamics of spatial heterogeneity, interactions and exchanges across heterogeneous landscapes, influences of spatial heterogeneity on biotic and abiotic processes, and the management of spatial heterogeneity. The main difference from traditional ecological studies, which frequently assume that systems are spatially homogenous, is the consideration of spatial patterns.[33]
A main concept in landscape ecology is scale. Scale represents the real world as translated onto a map, relating distance on a map image and the corresponding distance on earth.[36] Scale is also the spatial or temporal measure of an object or a process,[33] or amount of spatial resolution.[6] Components of scale include composition, structure, and function, which are all important ecological concepts. Applied to landscape ecology, composition refers to the number of patch types (see below) represented on a landscape and their relative abundance. For example, the amount of forest or wetland, the length of forest edge, or the density of roads can be aspects of landscape composition. Structure is determined by the composition, the configuration, and the proportion of different patches across the landscape, while function refers to how each element in the landscape interacts based on its life cycle events.[33] Pattern is the term for the contents and internal order of a heterogeneous area of land.[17]
A landscape with structure and pattern implies that it has spatial heterogeneity, or the uneven distribution of objects across the landscape.[6] Heterogeneity is a key element of landscape ecology that separates this discipline from other branches of ecology. Landscape heterogeneity is able to quantify with agent-based methods as well.[37]
Patch, a term fundamental to landscape ecology, is defined as a relatively homogeneous area that differs from its surroundings.[6] Patches are the basic unit of the landscape that change and fluctuate, a process called patch dynamics. Patches have a definite shape and spatial configuration, and can be described compositionally by internal variables such as number of trees, number of tree species, height of trees, or other similar measurements.[6]
Developments in landscape ecology illustrate the important relationships between spatial patterns and ecological processes. These developments incorporate quantitative methods that link spatial patterns and ecological processes at broad spatial and temporal scales. This linkage of time, space, and environmental change can assist managers in applying plans to solve environmental problems.[5] The increased attention in recent years on spatial dynamics has highlighted the need for new quantitative methods that can analyze patterns, determine the importance of spatially explicit processes, and develop reliable models.[33] Multivariate analysis techniques are frequently used to examine landscape level vegetation patterns. Studies use statistical techniques, such as cluster analysis, canonical correspondence analysis (CCA), or detrended correspondence analysis (DCA), for classifying vegetation. Gradient analysis is another way to determine the vegetation structure across a landscape or to help delineate critical wetland habitat for conservation or mitigation purposes (Choesin and Boerner 2002).[41]
Landscape ecology has been incorporated into a variety of ecological subdisciplines. For example, it is closely linked to land change science, the interdisciplinary of land use and land cover change and their effects on surrounding ecology. Another recent development has been the more explicit consideration of spatial concepts and principles applied to the study of lakes, streams, and wetlands in the field of landscape limnology. Seascape ecology is a marine and coastal application of landscape ecology.[48] In addition, landscape ecology has important links to application-oriented disciplines such as agriculture and forestry. In agriculture, landscape ecology has introduced new options for the management of environmental threats brought about by the intensification of agricultural practices. Agriculture has always been a strong human impact on ecosystems.[18]
In forestry, from structuring stands for fuelwood and timber to ordering stands across landscapes to enhance aesthetics, consumer needs have affected conservation and use of forested landscapes. Landscape forestry provides methods, concepts, and analytic procedures for landscape forestry.[49] Landscape ecology has been cited as a contributor to the development of fisheries biology as a distinct biological science discipline,[50] and is frequently incorporated in study design for wetland delineation in hydrology.[39] It has helped shape integrated landscape management.[51] Lastly, landscape ecology has been very influential for progressing sustainability science and sustainable development planning. For example, a recent study assessed sustainable urbanization across Europe using evaluation indices, country-landscapes, and landscape ecology tools and methods.[52]
