Gray–Green Spatial Structure and Nonlinear Threshold Effects on Street Crime: A CatBoost-Based Analysis of Day–Night Patterns in Shanghai

ISPRS International Journal of Geo-Information
Under rapid urbanization, street crime poses growing challenges to urban safety. Existing studies often treat gray and green spaces as independent variables, limiting the understanding of nonlinear crime patterns and spatiotemporal heterogeneity.

Beyond species loss: Community reshuffling shapes biodiversity along the urban–rural gradient

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Our results indicate that species turnover is a general ecological mechanism shaping vertebrate communities along the urban gradient, driven by taxon‐ and species‐specific responses to environmental and spatial features. Community differences primarily reflect habitat suitability rather than dispersal limitation, highlighting the potential of targeted ...

Rapid and Intense Declines of Forest Connectivity in the Amazon Arc of Deforestation Over Four Decades

Global Change Biology, Volume 32, Issue 6, June 2026.
Deforestation increased landscape fragmentation between 1990 and 2020. Ecological distance thresholds constrain gap crossing, seed dispersal, and pollen dispersal. Functional connectivity declined over time, while landscape modularity increased. ABSTRACT The Amazon Arc of Deforestation is facing a silent decline in ecological functionality.

Quantifying land use/land cover spatio-temporal landscape pattern dynamics from Hyperion using SVMs classifier and FRAGSTATS^®

Geocarto International, 2017
AbstractThis study aims to quantify the landscape spatio-temporal dynamics including Land Use/Land Cover (LULC) changes occurred in a typical Mediterranean ecosystem of high ecological and cultural significance in central Greece covering a period of 9 years (2001–2009).

Apparent Forest‐Cover Stability Conceals Structural and Functional Landscape Reorganization in a Human‐Modified Atlantic Forest–Cerrado Ecotone

Journal of Biogeography, Volume 53, Issue 6, June 2026.
ABSTRACT Aim To evaluate how long‐term forest turnover reshapes habitat structure and functional connectivity in a human‐modified Atlantic Forest–Cerrado ecotone landscape. Location Sarapuí River Basin, southeastern Brazil. Taxon Native forest vegetation and forest‐dependent taxa of the Atlantic Forest–Cerrado ecotone.

Investigation on the spatial pattern of regeneration patches in natural beech (Fagus orientalis Lipsky) forests (Case study: Gorazbon District, Kheyrud forest) [PDF]

مجله جنگل ایران, 2012
Natural processes and human activities continually change forest landscapes. Regeneration patches are one of the factors changing the forest landscapes. Knowledge of spatial patterns and structural analysis of patches are essential in sustainable forest ...

An Integrated Spatiotemporal Pattern Analysis Model to Assess and Predict the Degradation of Protected Forest Areas

ISPRS International Journal of Geo-Information, 2020
Forest degradation is considered to be one of the major threats to forests over the globe, which has considerably increased in recent decades. Forests are gradually getting fragmented and facing biodiversity losses because of climate change and ...

Análise factorial aplicada a métricas da paisagem definidas em FRAGSTATS

, 2004
Um programa de análise espacial baseado numa grelha de pixeis (FRAGSTATS 3.0) foi usado e os resultados da análise de 50 mapas de ocupação do solo usando esse programa são apresentados. Foram usadas 33 métricas da estrutura da paisagem e investigadas as propriedades das métricas para diversas paisagens (mapas de ocupação de solo de Portugal Continental)

Assessing multifunctional mountain landscape in an Eastern European framework

Geographical Research, Volume 64, Issue 2, May 2026.
The research introduces the Biocultural Resilience Index (BRI), a novel tool for assessing multifunctional landscape sustainability. By integrating biological, cultural, and socio‐economic indicators, the BRI identifies vulnerable areas and informs strategies for sustainable management.

Acoustic indices are not useful for biodiversity research

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1506-1518, May 2026.
Abstract Biodiversity assessment using passive acoustic monitoring has historically been challenging due to the limited availability of multi‐species acoustic detectors. In this context, acoustic indices were introduced as an alternative way to represent species diversity in acoustic datasets.
