The chances of an individual washing ashore or being carried by wind are greater for larger than for smaller islands, and greater for islands that are closer to other land (sources). Landscape ecology is the study of the structure, function, and changes in heterogeneous land areas composed of interacting organisms. Scott M. Pearson, in Encyclopedia of Biodiversity (Second Edition), 2013. These are a few of the emerging issues, but the socioecological complexity of land use decision-making should not be underestimated (Fischer et al., 2008). Thus seabed sediments that were previously stable under the prevailing current regime may become unstable, resulting in higher water turbidity and bedload sediment movement, forming ripples and dunes. Landscape ecology has been defined in various ways partly because the word, “landscape,” means quite different things to people with different scientific and cultural backgrounds. The average shape and size of patches can be assessed using the perimeter/area (P/A) ratio, a standard technique in landscape ecology (Pullin, 2002). Wide-ranging foraging species that feed preferentially within the original habitat will focus on the remaining patches in the fragmented habitat; this will tend to increase competition and predation within the patches of original habitat. All photos by Jianguo Wu. Thus, relatively small patches of unusual soils (i.e., edaphic islands) that are far from similar patches would be expected to have fewer species than large patches close to other areas of similar soils. Heterogeneity, scale, pattern–process relationships, hierarchy, disturbance, coupled ecological–social dynamics, and sustainability are among the key concepts in landscape ecology. Mosaics are highly suited to farmers engaged in marketing a range of products, in high rainfall areas, with access to sufficient land. Comments (0) Add to wishlist Delete from wishlist. The study of the distribution and abundance of elements within landscapes, the origins of these elements, and their impacts on organisms and processes. One of the main reasons for this lag is likely the paucity of disaggregate spatially explicit social science data. The diversity of perspectives can often be related to the philosophical underpinnings of reductionism versus holism. The study of the exchange of energy, organisms, materials, and other products of ecosystems is termed as the Landscape Ecology. Thus, landscape metrics have been widely used as crucial indicators, in studying sustainable planning and development. Landscape ecology is an emerging discipline that aims to understand the environmental processes and patterns influencing habitats and species beyond the site level. ‘Hierarchical’ refers to the multiplicity of organizational levels, spatiotemporal scales, and degrees of cross-disciplinarity in landscape ecological research. These data are necessary to test empirically the hypotheses derived from the theoretical constructs of individual human behavior. In their pioneering study, MacArthur and Wilson (1967) found that on a logarithmic plot, the number of species present on an island (S) is proportional to island area (A), given by: where “C” is the intercept of the Y-axis and “Z” is the slope of the line. Landscape ecology focuses on distribution and changes in the horizontal plane, whereas Critical Zone research appears to focus more on vertical distributions and changes. Rather, information on habitat condition and naturalness is also required to make an assessment. ScienceDirect ® is a registered trademark of Elsevier B.V.

These fields have had a rich history. Figure 2.17. In multifunctional landscape management many concerns can be taken on board in an approach based on landscape ecology, although there are criticisms that, because it is focused primarily on biodiversity issues, it currently fails to elaborate or model fully socioeconomic and cultural issues. Landscape metrics quantify the composition and configuration of ecosystems across a landscape (e.g., patch size, shape, nearest-neighbor distance, proximity index, etc.) In landscapes in which habitat is highly fragmented, isolated populations in small patches face a number of problems ranging from loss of genetic diversity to edge effects. Ecosystem Ecology It is the study of the entire ecosystem which includes the study of living and non-living components and their relationship with the environment. Landscape ecology provides many insights into the impact of land use structure and the function of agricultural systems (Wojtkowski, 2003). The persistent influence of land-use history and natural disturbance on contemporary ecosystems has become apparent. For example, land cover information derived from remotely sensed data, combined with other qualitative assessment data, can serve as a useful tool to evaluate human impacts on the landscape and, hence, on ecosystem sustainability (Burkhard et al., 2009). How can the knowledge of spatial heterogeneity help improve biodiversity conservation, planning, and management? Figure 1. At this level of ecological scale, the pattern of soil types on a landscape may have important ecological consequences. Even small changes in management, e.g., from conventional to minimum farm tillage, have implications for ecological outcomes such as carbon sequestration, runoff, soil loss, and habitat. What is landscape ecology? Landscape Ecology It deals with the exchange of energy, materials, organisms, and other products of ecosystems. One of these consequences is diversity (species richness, evenness). In China, the recycling of nutrients through dredging and hauling soil from water ways to fields was historically a primary nutrient cycling pathway, one that required considerable labor but was highly effective. Once spatial information on landscapes has been derived from remotely sensed data, pattern analysis can take place considering each landscape unit (e.g., land use/cover type) as part of a discrete patch mosaic. The Andes has been an ideal location to develop highly complex cropping systems that utilize diverse altitude niches (Fig. The patch–matrix–corridor model of describing spatial heterogeneity is a useful conceptual model that is directly applicable to populations. How can sustainable landscapes be developed and maintained? On the other hand, extinction is more likely to occur on small islands, where the diversity of habitats is less and resources are more limited than on larger islands. In Europe the challenge is often to mitigate the effects of development, but landscape ecology can be used more proactively to design for conservation and related benefits. Landscape ecology studies are characterized by spatially explicit methods in which spatial … Landscape ecology and population biology are exemplary. Thus, a landscape ecology of riparia is underpinned by two key ideas: Spatial configuration influences the relationships developed by living beings between themselves and their environment, requiring one to understand how spatial organization of the environment shapes processes that drive the dynamics of populations, communities and ecosystems (Turner et al. An understanding of population structure reveals the conservation challenges facing many species. “Nature” cannot be divorced from “man and society,” requiring one to be open to other disciplines often better qualified to study spatial organizations and humans (such as geography, history, anthropology, economy, and sociology). Landscape ecology is the science of studying and improving relationships between ecological processes in the environment and particular ecosystems. 2.7). Landscape ecology has been defined in various ways partly because the word ‘landscape’ means quite different things to people with different scientific and cultural backgrounds. Figure 1. Landscape ecology is the study of variation within and among landscapes at a variety of spatial and temporal scales. Over the past several years, interest in the field has burgeoned, resulting in an increasing number of published studies. How does landscape pattern affect the spread of disturbances such as pest outbreaks, diseases, fires, and invasive species? For example, geographical space is reduced to distance in a transportation cost model of location. Landscapes are spatial mosaics of interacting biophysical and socioeconomic components (Figure 1). However, productivity will vary greatly over a mosaic of widely varying plant types and mixtures. The natural sciences are further advanced than the social sciences in their theoretical developments of models of spatial processes. Landscape ecology is concerned with the causes and consequences of spatial pattern in nature at multiple spatial scales. In this case the heterogenous, disturbed, patchy habitat has a greater biodiversity than homogenous, undisturbed habitat. Ecology (from Greek: οἶκος, "house", or "environment"; -λογία, "study of") is the branch of biology which studies the interactions among organisms and their environment. 2.1 Theory: Landscape Modelling 2.2 Case Study: Oil Exploration and Rare Plant Conservation 2.3 Theory: Landscape Metrics Understanding the complexity of natural systems is a common goal of a variety of diverse disciplines in the Earth sciences and interdisciplinarity is a must. Ecosystem Ecology. This landscape-level pattern (i.e., the landscape structure) determines how populations are organized in local breeding groups and how frequently individuals move between these groups. No single paradigm exists that adequately defines how landscape models should be designed and tested. Some frameworks have been proposed to use the landscape approach to advance the integrated research of sustainable development, such as the principles of defining terms and concepts (e.g., Axelsson et al., 2011). Fig. The further offshore the island is located, the poorer the island species richness. These facilitate colonization and related mechanisms that help prevent species becoming extinct (Perfecto and Vandermeer, 2010). Landscape Ecology. Thus, the landscape ecology of populations is related to conservation. The patch–matrix–corridor model of describing spatial heterogeneity is a useful conceptual model that is directly applicable to populations. Landscapes are spatial mosaics of interacting biophysical and socioeconomic components (Fig. The advances in spatial analysis in the natural sciences, compared with the social sciences, are fairly straightforward to explain. Simmons, in Encyclopedia of Forest Sciences, 2004. Landscape Ecology draws together expertise from both biophysical and socioeconomic sciences to explore basic and applied research questions concerning the ecology, conservation, management, design/planning, and sustainability of landscapes as coupled human-environment systems. Our primary mission is to promote global collaborations, among our various chapters and with international policymakers. It is the study of the interaction between landscape patterns and ecological processes, especially the influence of landscape on the flows of water, energy, nutrients, and biota (Bourgeron and Jensen, 1994). The goal of landscape ecology is to understand the relationships between landscape pattern and ecological process; the role of humans and other forces of landscape change on these pattern-process relationships; and the principles required to make informed decisions in natural resource management. Landscape structure, in combination with life-history traits of a species, determines whether that species exists as a single large population, as a metapopulation of demes connected by movement of individuals, or as a collection of separate isolated populations. The power of landscape ecology is that its principles can apply at vastly different scales, depending on the landscape or the research question. Landscape ecology is not only a field of study, but also represents a new scientific perspective or paradigm that is relevant to a range of ecological, geophysical, and social sciences. We also serve as a platform for discussion and interactions across the disciplines. In addition, landscape ecology involves the application The International Association for Landscape Ecology (IALE) is the world wide organization of landscape ecologists. 2). As such, much may be learned by considering the techniques and findings of research conducted on other cat species such as leopards and cougars, as well as other large carnivores. “Pluralistic” indicates the necessity to recognize the values of different perspectives and methods in landscape ecology dictated by its diverse origins and goals. Concisely, landscape ecology can be described as the science of landscape diversity as the synergetic result of biodiversity … Landscape ecology is not only a field of study, but also represents a new scientific perspective or paradigm that is relevant to a range of ecological, geophysical, and social sciences. What is Landscape Ecology? Ecology deals with living organisms in the context of their natural environment. Further research is urgently needed into the role of mosaics and land sparing approaches in resilient rural landscapes. Nishanta Rajakaruna, Robert S. Boyd, in Encyclopedia of Ecology (Second Edition), 2019. landscape ecology. Landscape ecology is a search for patterns in ecological process as well as the causes and consequences of those patterns, often at landscape scales. These concepts form the basis of the Theory of Island Biogeography (Fig. In a similar manner, perennial and annual plantings of different age structures in an agricultural landscape can be planned, as strategies to both reduce risk and enhance returns. In multifunctional landscape management many concerns can be taken on board in an approach based on landscape ecology, although there are criticisms that, because it is focused primarily on biodiversity issues, it currently fails to elaborate or model fully socioeconomic and cultural issues. Landscape ecology is the study of patterns and processes of species assemblages and their interactions within landscapes. The theory of island biogeography predicts that untrawled patches that are small and isolated from other patches will (after the relaxation time) only support a subset of the original species diversity. How can ecological information be translated from fine to broad scales and vice versa? Also, until recently, there has been much more spatially explicit natural science data than social science data available for modeling and hypotheses testing, resulting in delayed response in the social sciences to spatially explicit problem solving (NRC 1997). Small islands that are far away from the mainland have the smallest number of species (S1), followed by large, far-away islands (S2), small, nearby islands (S3), and large, nearby islands have the largest number of species (S4). The intellectual thrust of this highly interdisciplinary enterprise is to understand the causes, mechanisms, and consequences of spatial heterogeneity, while its ultimate goal is to provide a scientific basis and practical guidelines for developing and maintaining ecologically, economically, and socially sustainable landscapes (Figure 2). "the study of … The power of landscape ecology is that its principles can apply at vastly different scales, depending on the landscape or the research question. They combined intellectual forces in the International Association of Landscape Ecology (IALE), formed in 1982. This field is highly cross-disciplinary, with people approaching landscape ecology from a number of perspectives, ranging from landscape architecture to energy conservation. 4.3B). In order to explain and predict these spatial processes, theoretical and empirical models must be developed to address where, when, and why these processes happen (Bockstael 1996). Example showing (A) undisturbed habitat; (B) effects of trawling disturbance removing parts of the original habitat; (C) changed conditions alters the composition of original habitat along exposed edges; (D) expansion of edge effects causes smaller patches (or elongated patches with a large P/A ratio) to contain only a subset of the original community. Edaphic islands of serpentine outcrops in the Klamath Siskiyou Mountain range in northern California. Landscape Ecology. Thus, a landscape ecology of invasive spread involves understanding how spatial pattern, such as habitat fragmentation or resource distributions, affects the various stages of the in-vasion process. The evidence is still out regarding whether management for high yield on one portion of land is associated with reduced pressure on other land, and subsequently, on enhanced opportunities for wildlife conservation and environmental service generation. This landscape-level pattern (i.e., the landscape structure) determines how populations are organized in local breeding groups and how frequently individuals move between these groups. Development of pattern metrics has largely stabilized, and they are widely used … Figure 4.3. Abstract Landscape ecology focuses on the reciprocal interactions between spatial pattern and ecological processes, and it is well integrated with ecology. Each of us was involved in the ‘‘birth’’ of these two fields. 2001, Farina 2006). This population structure in turn affects population dynamics. High productivity is common at the boundaries of different land uses, such as the interface of perennial trees and annual fields. In these studies, numerical landscape metrics derived from land cover maps were made available for analyzing landscape planning as well as ecosystem management. Thus, relatively small patches of unusual soils (i.e., edaphic islands) that are far from similar patches would be expected to have fewer species than large patches close to other areas of similar soils. This strategy is particularly important for clonal propagation materials, such as potato tubers, for seed. ‘Pluralistic’ indicates the necessity to recognize the values of different perspectives and methods in landscape ecology dictated by its diverse origins and goals. The explanation for the relationship between island area and species richness is that the number of species present on an island is governed by the rates of colonization and extinction.
