AI Article Synopsis

  • This study evaluates how urban expansion affects landscape patterns in coastal cities of Türkiye over 30 years, using various geospatial indices.
  • Analyzing six cities, it identifies two main types of landscape fragmentation: disconnected and perforated patterns, largely due to leapfrog development.
  • The findings provide insights for improving urban sustainability and can guide national strategies for urban planning in coastal regions of Türkiye.

Article Abstract

This study aims to evaluate the impact of urban spatial expansion on the landscape patterns of coastal cities in Türkiye through the use of spatio-temporal indices. To this end, temporal samples covering a period of approximately 30 years (1986-2000 and 2000-2015) were analyzed for six selected coastal cities in Türkiye. The urban spatial growth patterns in these cities were characterized using 17 geospatial indices, and Pearson's correlation coefficient and principal component analysis were employed to assess the quantitative relationships between urban spatial development and the fragmentation of landscape networks. The results of the study demonstrated that the patterns of landscape fragmentation caused by the spatial growth patterns of the selected coastal cities can be divided into two categories: disconnected landscape connections and perforated landscape patterns. Leapfrog development was identified as a major factor in the fragmentation of landscape continuity, leading to the formation of perforated green structures. The findings of this research can serve as spatial guidelines for addressing disconnected landscapes, a crucial factor in enhancing urban sustainability in Türkiye's coastal cities. Furthermore, the outcomes of this study may be useful for informing the national well-being strategy for urban planning and natural mitigating policies in Türkiye's coastal regions.

Due to their architectural and hydrodynamic properties, mangrove forests are emerging as global hotspots for plastic sequestration. Mangroves encroached by coastal cities contain up to two orders of magnitude more plastic than their non-urban counterparts. In urban mangroves, plastic substrata are often used as microhabitats, but the consequences of this interaction for the degradation process of plastics in the environment are unknown.

Tropical deforestation was found to cause large reductions in precipitation using a range of observation-based datasets. However, the limitations of satellite-based space-for-time statistical analysis have hindered understanding of the roles of reshaped mesoscale atmospheric circulation and regional precipitation recycling at different scales. These effects are considered nonlocal effects, which are distinct from the local effects governed by deforestation-induced reductions in evapotranspiration (ET).

Microplastics (MPs) are critical vectors for the dissemination of antibiotic resistance genes (ARGs); however, the prevalence and ecological risks of high-risk ARGs in mangrove ecosystems-globally vital yet understudied coastal habitats-remain poorly understood. To address this gap, this study investigated polyethylene, polystyrene, and polyvinyl chloride incubated in mangrove sediments for one month, focusing on high-risk ARGs, virulence gene (VGs), and pathogenic antibiotic-resistant bacteria within the mangrove plastisphere. High-throughput PCR and metagenomic analyses revealed that high-risk ARGs, VGs, and mobile genetic elements (MGEs) were significantly enriched on MPs compared to surrounding sediments.

Introduction: With rising urbanization and global climate change, sustainable city development has become an urgent challenge. Emerging mobility services provide innovative solutions for sustainable city governance, bridging the gap between transportation demand and supply, alleviating city travel and reducing carbon emissions. However, further investigation is needed to ascertain the specific roles and potential enhancements that emerging mobility services could contribute to reducing carbon emissions.

The benefits to humans of living by the ocean have led many coastal settlements to grow into large, densely populated cities. Large coastal cities have had considerable environmental effects on marine ecosystems through resource extraction, waste disposal, coastal development, and trade and travel routes. While our understanding of the ecological and evolutionary consequences of urbanisation for wildlife in terrestrial systems has received considerable recent attention, the consequences of urbanisation in marine systems are not well known.
