“…The search for the most accurate representation of landscape functionality to guide biodiversity conservation and landscape connectivity planning remains relevant to science and a bottleneck for governmental agencies and decision-makers in general. Despite the difficulties in acquiring data in loco, the use of functional connectivity metrics, even if based on secondary data, as observed in other studies [1,2,39], was more accurate when comparing areas than applying simple structural metrics. However, the applicability of this measure faces dilemmas, such as the transposition of information from a local to a global scale, for example, data on the dispersal of species [103].…”

“…The analysis of the landscape structure was performed using a set of metrics usually applied in the studies of landscape ecology for biological conservation [35,[39][40][41] (Table 1, Equations ( 1)-( 6)). Forest patches were assessed for their Optimal Resource Availability (ORA), calculated in ArcGIS ® (extension V-Late) using information on shape (Fsh), their size coefficients (CS), and the physiognomic importance of the forest patches (CF), an adaptation of the literature [39,42] with the inclusion of CF. Weighting CF was performed to enhance the natural habitat of the Cerrado species used in the functional analysis of this study, some of which are exclusive to this Biome.…”

Landscape connectivity can be assessed based on the physical connection (structural connectivity) or the maintenance of flow among habitats depending on the species (functional connectivity). The lack of empirical data on the dispersal capacity of species can lead to the use of simple structural measures. Comparisons between these approaches can improve decision-making processes for the conservation or restoration of habitats in fragmented landscapes, such as the Cerrado biome. This study aimed to understand the correspondence between the measures of landscape structural and functional connectivity for Cerrado plants. Three landscapes with cerradão patches in a pasture matrix were selected for the application of these metrics based on the functional connectivity of four profiles of plant dispersal capacity. The results showed divergent interpretations between the measures of landscape structural and functional connectivity, indicating that the assessment of biodiversity conservation and landscape connectivity is dependent on the set of metrics chosen. Structurally, the studied landscapes had the same number of cerradão patches but varied in optimal resource availability, isolation, heterogeneity, and aggregation. Functional connectivity was low for all profiles (based on the integral index of connectivity—IIC) and null for species with a low dispersal capacity (based on the connectance index—CONNECT), indicating that species with a medium- to long-distance dispersal capacity may be less affected by the history of losses and fragmentation of the Cerrado in the pasture matrix. The functional connectivity metrics used allowed a more robust analysis and, apparently, better reflected reality, but the lack of empirical data on dispersal capacity and the difficulty in choosing an indicator organism can limit their use in the management and planning of conservation and restoration areas.

“…According to principles of landscape ecology, the processes associated with environmental conservation can be inferred from patterns of vegetation composition and distribution and land uses (Turner et al, 2001). Based on this approach, structural patterns can be assessed by using landscape metrics or indexes (McGarigal and Marks, 1995), such as quality of the forests based on size, shape, isolation, succession stage, and anthropic boundaries (Zeng and Wu, 2005;Hardt et al, 2013aHardt et al, , 2014.…”

The clearing of native vegetation in water source areas and its effects on water supply availability have become a major concern in large metropolises. This study examined the spatial and temporal changes in land use and cover and their effects on the conservation of Atlantic Forest in a water source area in the Metropolitan Region of São Paulo that is the second most densely populated territory in Brazil, the municipality of Diadema. Historical maps and trend scenarios were developed by applying the Markov chain in association with cellular automata. Forest conservation was assessed based on a set of landscape metrics of resource availability, fragment isolation, and trends of forest fragmentation. Our findings revealed an increase in urban growth of 37% in the last five decades directly associated to the clearing of 50% of forests in intermediate/advanced stages and 40% in early stages. The main drivers of landscape change were human-modified fields (41%) and net roads (54%). Optimal resource availability was drastically reduced (75%) while isolation increased (361.5%) among existing forest fragments. Therefore, future trends indicate that, without changes in the management of the area, deforestation may occur rapidly and continuously until 10% of forest remains, leading to potential adverse effects on water availability and quality of the Billings Reservoir and the local biodiversity.

“…Conforme já apontado na introdução desta pesquisa, o conceito passou a ser reconhecido após a Avaliação Ecossistêmica do Milênio (Millenium Ecosystem Assessment, MEA), reconhecido pela Convenção da Diversidade Biológica (CBD) e pelo setor empresarial(WRI, 2012, CEBDS, 2013. Destacam-se ainda os pesquisadores que trouxeram consistência ao assunto, conforme apontado porMunk (2015): botânico Walter Westman (na década de 70),Fisher et al (2009),Santos (2014) e Paul e Anne Ehrlich (1981). A Tabela 1 a seguir (segundoMunk, 2015), mostra um histórico do conceito sobre SE, o que demonstra o avanço perante as resistências e fragilidades da área temática.…”

The way of life established on the planet depends on the natural resources and the benefits they offer. Human transformations in natural systems intensified in the twentieth century and numerous protection strategies were developed and proposed in the scientific and institutional field. Ecosystem services emerged in this movement and aim to identify the carrying capacity of natural capital stocks in relation to the needs and benefits associated with human beings and their resilience of the system, which is pointed as a cascade of interconnected processes. Since the 1980s, the concepts of ecosystem services have been discussed, considering their nature and their monetization in the areas of environmental and ecological economics. In general terms are considered Ecosystem Services what ecosystems produce for human well-being and the maintenance of quality of life, and the service does not exist without the need for well-being, which does not necessarily mean preserving nature. A milestone on the subject was the Millennium Ecosystem Assessment (2005) document, which referred to the assessment of the state of degradation, trends and priorities of ecosystem protection. Through a bibliographical review about Ecosystem Services, the objective of this dissertation was to search how the aspects of the physical environment are approached in this area of knowledge. Two weaknesses accompany the knowledge on this topic: (i) the differentiation of concepts and methodologies, where applications vary according to the purpose of each study and / or research and (ii) the gaps between interactions of ecosystem functions including aspects of environment within the Ecosystem Services scenario. It was observed that the variables and methods applied use the aspects of the physical environment if so pointed in the demands for ecosystem services. Considering that ecosystems are the interaction between biotic and abiotic factors, and that ecosystem functions integrate aspects of the physical, biotic, socioeconomic and cultural environments, it is important to consider the aspects of the physical environment in relation to processes of surface dynamics. in the Ecosystem Services scenario, facing the vectors of change, in different spatial and temporal scales, aiming at the maintenance of environmental quality and life in the medium and long term. In this context, it was understood that the definition of landscape units could collaborate in the evaluation of ecosystem services in an integrated way. Defining in this case that the landscape unit would be constituted of a physiographic territorial base and its associated environmental and cultural attributes. The physiographic basis as a system with physical delimitation constituted by the aspects of the physical environment and their susceptibilities to the processes of surface dynamics, interconnected and interdependent internal and external characteristics, including the laterality, horizontality and verticality flows, could evidence the organization of attributes in space in a set that den...
