Summary: The study evaluates the impact of coarse graining on the fit and accuracy of scaling functions for downscaling/prediction. The results show that the power law consistently fits all compositions/configurations, and configuration has a greater effect on downscaling accuracy. Majority rules aggregation preserves information better with dispersed land covers, and downscaling accuracies are highest around power law exponents of -0.5.

Summary: This study evaluates the change of urban growth pattern and the land use policies that caused this change in Ankara, the capital of Turkey. The results show that different land use decisions at different scales affect the urban growth trend, and spatial metrics can help determine the urban growth pattern and landscape change dynamics. The findings provide important insights for the development of urban land use strategies.

Summary: The land surface temperature (LST) of urban areas plays a crucial role in urban environmental monitoring, and thermal infrared remote sensing has proven to be an effective method for obtaining LST. However, the traditional thermal radiance transfer model assumes a flat land surface, which does not hold true for the complex urban landscape. This study proposes a new ultrahigh spatial resolution urban thermal radiance transfer model (UHURT) that successfully quantifies multiple scattering and adjacent effects, leading to improved LST retrieval results and reduced errors in the urban landscape.

Summary: Urbanization in India is causing negative impacts on the environment and human health due to the expansion of built-up areas and the decline of vegetation and water bodies. To address this issue, the study examines urban expansion processes in English Bazar Municipality. The study identifies an increase in built-up areas accompanied by decreased vegetation and increased fragmentation over time. To promote sustainable urban development, stakeholders and the government should prioritize the conservation and creation of green and blue spaces through the incorporation of green infrastructure, smart city principles, community engagement, and partnerships with local businesses.

Summary: ContextPattern metrics derived from image processing and remote sensing are used as descriptors of landscape gradient texture. These metrics measure different aspects of texture by examining the frequencies of co-occurring pixel values on a map. In order to improve their interpretation and application in landscape ecology, several of these metrics are reformulated and interpreted using analogies to traditional metrics for categorical data.

Summary: This study proposes a scientific definition and conceptual connotation of Sustainable Landscape Pattern (SLP) and summarizes its application status in spatial planning. The results show that SLP effectively supports spatial planning by helping determine planning targets, analyze spatial patterns, and compare and select schemes. Future research directions include exploring frontier concepts like spatial resilience and applying SLP to ecological restoration and urban development.

Summary: The study analyzes the impact of disturbances in the ecological landscape on the spatial distribution of a population evolving according to the nonlocal FKPP equation. It characterizes the three types of stationary profiles that can develop near abrupt spatial variations in environmental conditions, and discusses how heterogeneities can reveal hidden information in a flat landscape through mapping between induced wrinkles and the shape of the interaction kernel.

Summary: Intensive human activities induced by urban development can alter the air quality of the urban area and its surrounding regions. The composition of the urban landscape is found to be associated with air pollutant concentrations, but different studies have yielded conflicting results. As a result, uncertainties arise, making it challenging to determine optimized urban landscapes for policy implementation.

Summary: Sahelian landscapes in northern Burkina Faso have undergone rapid changes in the past decades, influenced by population growth, climate hazards, and land degradation. This research analyzed land use/land cover patterns, assessed seasonal vegetation dynamics, and predicted future changes using remote sensing and neural network modeling. The results indicate a significant increase in cultivated areas by 2030 and 2050, emphasizing the need for sustainable land management practices to balance agricultural production and natural resource conservation.

Summary: A novel approach based on multispectral remote sensing techniques was developed to evaluate the ecological status and disturbances of Iranian mangroves. The approach involved calculating a spatial disturbance index (SDI) using landscape metrics and principal component analysis (PCA). The results showed that the selected metrics could effectively quantify the SDI and identify different levels of disturbances. This approach enables the detection and management of disturbances in mangrove ecosystems.

Summary: Bayesian methods have been developed to infer the true year of extinction of a species by considering both certain and uncertain sighting records. By relaxing the constant rate assumption in the homogeneous Poisson process, the model can accurately identify changes in sighting rates leading up to extinction. Applied to the black-footed ferret and the ivory-billed woodpecker species, the results of the method indicate extinction years in 1988 and 1956 respectively.

Summary: Misunderstandings regarding species' ecological preferences hinder conservation efforts. In areas where humans and elephants coexist, conflicts arise in various forms, posing a significant threat to the endangered Asian elephant. The study in Peninsular Malaysia revealed distinct habitat preferences between female and male elephants, with conflicts occurring in highly suitable habitats, especially for females. Mitigation strategies for human-elephant conflicts should take into account the ecological and social dimensions to promote coexistence.

Summary: Joint species distribution models (JSDMs) that explicitly account for imperfect detection can accurately estimate intrinsic correlation between species with sufficient survey sites and replications. However, reducing the number of survey sites decreases precision of estimates, while reducing the number of survey replications can lead to biased estimates. For low detection probabilities, a large number of survey replications may be required to remove bias from estimates. JSDMs not explicitly accounting for detection have limited ability to disentangle detection from occupancy, reducing their ability to accurately infer species distribution spatially.

Summary: The Tasmanian Midlands, a privately-owned agricultural region with significant land degradation and loss of biodiversity, has been the focus of conservation efforts since the 1980s. Over the past four decades, relationships of trust and collaboration between local farmers and conservation planners have been crucial for the success of conservation planning and implementation, which has evolved from site-level to landscape-scale approaches incorporating ecological restoration in its broadest sense.

Summary: Large-scale reforestation under future climates has both positive and negative impacts on the water cycle. In most water-insecure regions in the Asia-Pacific, reforestation increases evapotranspiration and precipitation, resulting in higher water yield and reduced probability of extreme dry months. However, some regions may experience declines in net water yield due to increased evapotranspiration or decreases in soil moisture and advected precipitation.
