The growing recognition that spatial scale and heterogeneity affect ecological processes has focused heightened attention over the last decade on principles from the field of landscape ecology. Landscape ecologists, drawing on principles from a diverse array of disciplines and fields, including physical and human geography, focus explicitly on the interrelation between landscape structure (i.e., pattern) and landscape function (i.e., processes). In this article, I discuss the application of landscape ecological principles to a specific and pressing issue: nature reserve design and functioning. To do so, I outline and review five landscape ecological themes with relevance to reserve design and management: reserve distribution, reserve shape, landscape corridor design and functioning, boundary dynamics, and reserve functioning. I particularly stress: 1) the role that landscape ecological theories may have in integrating existing principles from applied biogeography and population biology, and 2) the unique insights provided by a landscape ecological approach. Finally, I argue that biogeographers, because of our distinct skills, need to be more active in the development and advancement of landscape ecological theory.

Abstract Context The 25th anniversary of the founding of the UK chapter of the International Association for Landscape Ecology (ialeUK) was marked in 2017. Objectives To assess trends in UK landscape ecology research over ialeUK’s first 25 years, to compare these trends to changes elsewhere in the world, and to consider how ialeUK can continue to support landscape ecology research and practice. Methods A database of conference abstracts was compiled and examined in combination with a questionnaire that surveyed existing and former active members of ialeUK. Results Across 1992–2017 we observe noticeable trends including the declining roles of statutory bodies, the development of the ecosystem services concept, and a decrease in use of empirical methods. Analysis of questionnaire results highlighted four key areas: Developing new researchers; Facilitating conferences for networking, learning and discussion; Linking policy with practice; and Driving the continued growth of landscape ecology as a discipline. Challenges were also noted, especially regarding the adoption of a wider understanding of landscape ecological principles in management. Conclusions Increases in qualitative research, decreases in studies explicitly examining connectivity/fragmentation and an absence of landscape genetics studies in the UK are seemingly distinct from US landscape ecology and elsewhere around the world, based on published accounts. ialeUK has had success in increasing the role of landscape ecology in policy and practice, but needs to continue to aim for improved collaboration with other landscape-related professional bodies and contributions to wider sustainability agendas.

Abstract Context:The impulse to write this contribution was the effort of co-authors to bring the European landscape ecologist closer to the development, research & didactic approaches and possible future development of landscape ecology in Mexico from the theoretical, metascientific and applied point of view. Purpose: The purpose of the metascientific approach, in this case meta-landscape ecological approach, is to increase the degree of generalization of existing empirical-methodological, theoretical-application and didactic knowledge and results of landscape-ecological research, so that generally valid landscapeecological regularities and principles can be determined The aim was to acquire new generalizing and holistic qualities and perspectives in the field of landscape ecology in Mexico at this level. Methods: The two-step methodical procedure was elaborated, using metascientifically oriented landscape ecological and ecological Mexican literature, complemented by our studies and personal experience. Results: In this way, new knowledge, representing the added value and meaning of landscape ecologicalevolution, research, education and future development in Mexico was gained. It will serve also to Mexican landscap ecologists. Conclusiones: Mexican landscape ecology, lying at the intersection of European and American landscape ecology, can be described as integrative, idiographic-nomothetic at the spatial level of the landscape in the contact zone of European and American research approaches and principles.

<em>Abstract</em>.—Traditional approaches to fish conservation have focused on the protection of small habitat patches or on individual species at risk of extinction. These strategies have been important yet largely have been too little and too late for widespread protection of aquatic faunas. Such small-scale and reactive approaches also are costly in terms of recovery programs and aggressive in terms of regulatory controls. Further, the linear nature of streams and the networked configuration of drainage systems suggest that a fundamentally different approach to reserve design and protected areas is necessary for effective conservation of freshwater communities when compared to terrestrial systems. Larger-scale, multispecies approaches to native fish conservation offer a more efficient and effective conservation strategy because entire fish communities and the ecological processes that support maintenance of habitat diversity can be sustained before the status of individual species deteriorates to critical levels. Protecting entire communities and watersheds also offers some resistance to climate change impacts, which rapidly are altering flow regimes and disturbance dynamics in aquatic systems. Identification and protection of high-value aquatic communities will provide an important supplement to current conservation strategies during times of increasing threats and future uncertainty.

Heterogeneity is a defining characteristic of landscapes and therefore central to the study of landscape ecology. Landscape ecology investigates what factors give rise to heterogeneity, how that heterogeneity is maintained or altered by natural and anthropogenic disturbances, and how heterogeneity ultimately influences ecological processes and flows across the landscape. Because heterogeneity is expressed across a wide range of spatial scales, the landscape perspective can be applied to address these sorts of questions at any level of ecological organization, and in aquatic and marine systems as well as terrestrial ones. Disturbances—both natural and anthropogenic—are a ubiquitous feature of any landscape, contributing to its structure and dynamics. Although the focus in landscape ecology is typically on spatial heterogeneity, disturbance dynamics produce changes in landscape structure over time as well as in space. Heterogeneity and disturbance dynamics are thus inextricably linked and are therefore covered together in this chapter.

Ecosystem and Landscapes - A Critical Comparative AppraisalEcosystems and landscapes are the two major spatial units for ecological research and practice, but their definitions and meanings are vague and ambiguous. Examining critically the meaning and complexity of both terms from a holistic landscape ecological systems view, the confusing applications of the ecosystem concept could be avoided by conceiving ecosystems as functional interacting systems, characterized for the flow of energy, matter and information between organisms and their abiotic environment. As functional systems they are intangible with vaguely defined borders. On the other hand, landscapes should be recognized as tangible, spatially and temporally well defined ecological systems of closely interwoven natural and cultural entities of the Total Human Ecosystem. Ranging from the smallest discernable landscape cell or ecotope to the global ecosphere, they serve as the spatial and functional matrix and living space for all organisms, including humans, their populations and their ecosystems. Both are medium-numbered complex ecological systems. However, the organized complexity of ecosystems is based solely on the monodimensional complexity of material processes of flow of energy/matter and biophysical information. But the organized complexity of landscapes is multidimensional and multifunctional, dealing not only with the functional dimensions of natural bio-ecological processes and the natural biophysical information, but also with the cognitive mental and perceptual dimensions, transmitted by cultural information and expressed in the closely interwoven natural and cultural landscape.

Many agricultural landscapes are characterized by a high degree of heterogeneity and fragmentation. Landscape ecology focuses on the influence of habitat heterogeneity in space and time on ecological processes. Landscape epidemiology aims at applying concepts and approaches originating from landscape ecology to the study of pathogen dynamics at the landscape scale. However, despite the strong influence that the landscape properties may have on the spread of plant diseases, landscape epidemiology has still received little attention from plant pathologists. Some recent methodological and technological progress provides new and powerful tools to describe and analyse the spatial patterns of host–pathogen interactions. Here, we review some important topics in plant pathology that may benefit from a landscape perspective. These include the influence of: landscape composition on the global inoculum pressure; landscape heterogeneity on pathogen dynamics; landscape structure on pathogen dispersal; and landscape properties on the emergence of pathogens and on their evolution.
