“…It is important to consider human influence on ecological connectivity and biodiversity conservation. Human influence is one of the main drivers of landscape change and loss of biodiversity [48,49]. Nighttime light pollution caused by humans has influenced the physiological and behavioral pattern of organisms, and thus threatened biodiversity, but it has been persistently ignored in macroecology and ecological connectivity research [50,51].…”

Anthropic pressure is one of the main drivers of landscape change and biodiversity loss. Artificial nighttime light, which can affect species behavior, is an important human-induced threat to biodiversity, but it is often ignored in ecological connectivity research. To mitigate the adverse impacts of artificial lighting on biodiversity, this study integrates artificial nighttime light in landscape ecology and analyzes the influence of artificial nighttime light on landscape connectivity. A quantitative approach integrating nighttime light brightness from a Visible Infrared Imaging Radiometer Suite (VIIRS) with a normalized difference vegetation index (NDVI) from a Moderate-resolution Imaging Spectroradiometer (MODIS) is proposed to estimate the matrix resistance, which can identify the sensitive areas that are disrupted by nighttime light. It was found that the nightscape in the study area is significantly disrupted by nighttime light and the matrix resistance in the center of the study area significantly increases. Compared to the least-cost routes from the NDVI, the “dark” least-cost ecological corridors constructed using our approach apparently change in both location and distance. The corridors moved to the outer suburbs and rural areas, and the maximum increase in distance of the least-cost paths was 37.94%. Due to less disturbance from human activity and the maintenance of a pristine nightscape, “dark” ecological corridors can reduce the adverse effects of night lights and contribute to biodiversity. However, natural habitats have been greatly affected by nighttime light with the increase in global illumination, and it is essential that we improve public awareness of light pollution and formulate light-reduction policies and legislation.

“…The analysis of human disturbance in the ecological environment based on the classification of land cover can comprehensively evaluate the cumulative results of various artificial effects and can accurately show the spatial distribution and gradient change characteristics of artificial influences. Based on previous research, the existing classification standards of human disturbance, and the actual situation of the study area, the corresponding hemeroby index (HI) was assigned to different types of LULC [24,36], and the assigned LULC types were divided into three categories: undisturbed, partially disturbed, and completely disturbed (Table 3). Then, we used the Create Fishnet function in ArcGIS 10.3 to create grid units and a grid of 1 km × 1 km with a total of 2732 as the evaluation unit was constructed for sufficient sample size and accuracy.…”

The wetland ecosystem along a river in a coastal region has great significance in purifying water bodies, regulating climate, and providing habitat for animals and plants. Studying the effects of human disturbances on the landscape patterns of wetlands is of great significance to the protection and management of an ecosystem. This study used Guannan County and Guanyun County, two counties in China that are located on both banks of the Xinyi River as the study area. The spatiotemporal characteristics of the landscape pattern evolution of wetlands and their relationship with human interference from 2009 to 2020 were analyzed by the landscape dynamic rate, landscape conversion matrix, landscape indices, human disturbance index, and the quadratic regression equation. The results showed that: (1) Except for the increase in the area of beach and paddy fields, the area of other landscape types decreased; (2) the changes in wetlands were heterogeneous and showed different trends in different regions; (3) the boundary shape’s complexity and the landscape pattern’s fragmentation showed a decreasing–increasing trend and the connectivity and the diversity of the landscape decreased; and (4) the human disturbance index increased from 2009 to 2014 and then decreased from 2014 to 2020, declining outward from the places where towns and construction land aggregated. Moreover, there was an inverted U-type relationship with the landscape pattern indices. The findings provide direct, specific, and explicit information and theoretical guidance for the protection of wetlands along the river in the coastal region as well as for the restoration of wetland ecosystem function and the improvement of wetland biodiversity in relevant regions.

“…Essa preocupação/utilização surge devido aos significados que a perda de naturalidade da paisagem indica para todos aqueles que dela dependem (Machado, 2004). Dentre estas acepções, a qualidade da relação humana com a biodiversidade e os serviços ecossistêmicos no espaço aparece frequentemente como objeto de pesquisa, principalmente, em estudos que estimam os resultados de sua sucessiva intervenção na composição e estrutura da paisagem (Chi et al, 2018;Zhou et al, 2018;Han et al, 2020;Yang & Song, 2021).…”

“…Diversos estudos relacionados à Ecologia da Paisagem utilizam esta tipologia de índices para monitorar e avaliar as pressões humanas na paisagem (Walz & Stein, 2014;Szilassi et al, 2017;Yi et al, 2021;Gusmão et al, 2021). Estes autores conseguiram indicar as particularidades de cada região por meio de intervalos de classificação de hemerobia (maior pressão, menor naturalidade) para suas áreas de estudo.…”

Resumo - Este estudo avalia o trade-off de desenvolvimento econômico e conservação em dois municípios, Pirapora/MG e Buritizeiro/MG, com o objetivo de identificar e quantificar as principais pressões antrópicas sobre o Cerrado da área de estudo e seus serviços ecossistêmicos usando métricas da paisagem. A pesquisa utilizou a abordagem de índices de hemerobia a partir dos mapas de uso e cobertura do MAPBIOMAS de 1985 a 2021 para caracterizar a composição e configuração da paisagem e as possíveis ameaças ao bioma do Cerrado. Entre os anos de 2014 e 2021, as transições de uso da terra, antes mais suscetíveis às outras lavouras temporárias e silvicultura, foram mais presentes para as classes de outras lavouras perenes, de soja e de citrus, indicando algumas das transformações produtivas no mosaico. Nossos resultados também quantificaram o impacto humano moderado sobre a paisagem no corte temporal avaliado. O índice hemerobiótico alterou de 2.461 em 1985 para 2.737 em 2021. As alterações percebidas nos registros indicam transformações do uso da terra para a sedimentação de um modelo agroexportador. Deste modo, a região pode estar numa nova fronteira agrícola para a instalação/fortalecimento de culturas voltadas para a exportação. Palavras-chave: Meio Ambiente. Desenvolvimento Econômico. Conservação. Cerrado. Norte de Minas. Abstract - This study assesses the economic development and conservation trade-off in two municipalities, Pirapora/MG and Buritizeiro/MG, with the objective of identify and quantify the main anthropogenic pressures on the Cerrado of the study area and its ecosystem services using landscape metrics. This research used the hemeroby indices approach from the MAPBIOMAS use and coverage maps from 1985 to 2021 to characterize the composition and configuration of the landscape and possible threats to the Cerrado biome. Between the years 2014 and 2021, land use transitions, previously more susceptible to other temporary crops and forest plantation, were more present for the classes of other perennial crops, soybean and citrus, indicating some of the productive transformations in the mosaic. Our results also quantified the moderate human impact on the landscape in the evaluated temporal cut. The hemobiotic index changed from 2.461 in 1985 to 2.737 in 2021. The changes perceived in the records indicate transformations in land use for the sedimentation of an agro-export model. In this way, the region may be on a new agricultural frontier for the installation/strengthening of export-oriented crops. Keywords: Environment. Economic Development. Conservation. Cerrado.
