Land managers must find a compromise between rapidly changing landscapes and biodiversity conservation through ecological networks. Estimating networks is key approach to enhance or maintain functional connectivity by identifying the nodes links of graph, which represent habitats their corresponding corridors, respectively. To understand current state biodiversity, it necessary consider dynamic landscape while relying on relevant land cover maps. Although map relatively easy produce using existing data, this challenging for past landscapes. Here we investigated impact changes in an urban at fine scale habitat availability two bird species: tree pipit Anthus trivialis short-toed treecreeper Certhia brachydactyla. These species, exhibiting different niche ecologies, have shown contrasting population trends medium-term scale. The occurrences C. brachydactyla were better correlated with resistance values that maximise use whereas A. fitted intermediate values. statistical indirectly highlighted information about ecology capacity both species habitats. Landscape increased over 24-year study period may implications local abundances, could explain, national scale, increase populations brachydactyla, but not decrease trivialis. Thus, more attention be paid rural associated are impacted human activities, efforts also achieved areas especially highly corridor-dependent species. Studying essential estimating future impacts networks, reconcile concerns management.

Public Vitality-Driven Optimization of Urban Public Space Networks—A Case Study from Nanjing, China

Smart Cities, Journal Year: 2025, Volume and Issue: 8(1), P. 18 - 18

Published: Jan. 24, 2025

Spontaneous recreational activities in public spaces are a vital source of vitality. Given the similarity between walking patterns crowds and movement electrons on two-dimensional circuit surface, this study combines big data from various sources to create an “electrical conductivity surface” that attracts aggregates crowds. Using current flow simulation, we generate path selection preferences people as they move across spaces. The results reveal uneven distribution Nanjing’s main urban area, with high-vitality areas mostly concentrated center. core demand for enhancing vitality lies is improving connectivity multiple Based this, space plan area emphasizes overall by aligning natural landscape, thus linking city’s green gray infrastructure. In study, have assessed services their development potential number different angles, developing digital approach optimizing layout. We aim provide human-centric, bottom-up perspective complement top-down city planning management approach. This will enable planners make informed decisions creating managing more vibrant cities.

Dynamic connectivity assessment for a terrestrial predator in a metropolitan region

Frontiers in Ecology and the Environment, Journal Year: 2024, Volume and Issue: 22(4)

Protecting wildlife movement corridors is critical for species conservation. Urban planning often aims to create animal through conservation initiatives. However, research on connectivity urban limited. Here, we assessed coyotes ( Canis latrans ) dynamically across temporal scales and demographic traits, parametrized using the habitat selection of 27 global positioning system (GPS)‐collared in city Toronto, Canada. The models accounted human population density, impervious area, vegetation distance different linear features. Results indicated that (1) vegetation‐dense areas were key areas; (2) riverbanks, railways, below power lines predicted as corridors; (3) commercial industrial clusters strongly disrupted connectivity. Spatiotemporal differences associated with time day coyote social status but not climate biological seasonality or age sex. Residential roads pivotal dynamism maintenance enhancement plant structural complexity along infrastructure (for example, highways, waterways, parking lots) should be considered when managing cities.

Nature-based solutions for urban biodiversity: Spatial targeting of retrofits can multiply ecological connectivity benefits

Landscape and Urban Planning, Journal Year: 2024, Volume and Issue: 251, P. 105169 - 105169

Published: July 18, 2024

Protecting and enhancing biodiversity in urban areas is critical for meeting international conservation commitments, has a vital role to play the health wellbeing of city residents. Yet, urbanisation can have devastating impacts on biodiversity, with development typically delivering landscapes which habitat remains only as small, fragmented patches, surrounded by an inhospitable matrix. As cities begin plan alongside other land use considerations, planners leverage ecological knowledge planning concepts aid decision making deliver benefits nature people. Here we demonstrate how targeted green infrastructure placement potentially increase delivery landscape level improving connectivity native species. We measure change when parking spaces are converted small across City Melbourne, Australia. test three reallocation scenarios varying levels space conversion spatial prioritisation connectivity. While scenario that maximised number performed best, show greening delivered strongest outcomes per unit area converted. Improvements were two times higher effort was towards locations identified important barriers landscape-level movement.

Urban landscapes are rapid changing ecosystems with diverse urban forms that impede the movement of organisms. Therefore, designing and modelling ecological networks to identify biodiversity reservoirs their corridors crucial aspects land management in terms population persistence survival.

Abstract The western-European hedgehog ( Erinaceus europaeus ) is an insectivore with a wide distribution in Portugal and potential tool for biomonitoring relevant One Health hazards, including heavy metal(loid)s’ pollution. aim of this study was to positively contribute the current knowledge about metal(loid) pollution Portugal. Forty-six hedgehogs (from rescue centres; known provenance) were necropsied. Sex, age category weight determined. Spines, liver kidney collected, metalloid concentrations determined by inductively coupled plasma mass spectrophotometry (ICP-MS). In general, results did not present alarming concentrations, exception cadmium (Cd) (in kidneys) copper (Cu). Hedgehogs from Viana do Castelo Viseu showed elevated arsenic (As) Branco presented concerning values (Cd). Adult heavier tended higher levels metal(loid)s. Sex does seem significantly affect concentrations. Further analysis would be needed prioritize areas detail allow application necessary mitigation strategies.
