Spatial change and scale dependence of built-up land expansion and landscape pattern evolution—Case study of affected area of the lower Yellow River

Ecological Indicators, 2022
Land use change are essential for sustaining human wellbeing, but empirical studies have shown that the urban development requires built-up land, yet, the disorderly expansion of built-up land poses a threat to sustaining the stability of landscape ...

Characterising three decades of evolution of forest spatial pattern in a major coal-energy province in northern China using annual Landsat time series

International Journal of Applied Earth Observations and Geoinformation, 2021
The analysis of change processes in relation to spatial patterns is gaining increasing attention in landscape ecology. Forest spatial pattern change is a critical process in landscape dynamics, and has a significant impact on the biodiversity, habitat ...

Predicting Ecosystem Pattern across Landscapes

Oikos, 2022
Predictive modelling is fundamental to ecology and essential for objective biodiversity assessment. However, while predictive biodiversity models are generally well-developed, models for predicting patterns within and among ecosystems have not been adequately operationalized.

Venous Thromboembolism in Pediatric Bone Sarcoma Patients: A 10‐Year, Single‐Institution Experience Encompassing the COVID‐19 Pandemic

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Osteosarcoma (OS) and Ewing sarcoma (EWS) are the most common primary bone cancers in children, but acute thrombosis is poorly characterized in this population. Our study evaluated the rates of venous thromboembolism (VTE) and associated risk factors in pediatric patients with bone sarcomas treated over a 10‐year period encompassing

Fragmentation of Araucaria araucana forests in Chile: quantification and correlation with structural variables

iForest - Biogeosciences and Forestry, 2016
Landscape fragmentation is one of the main threats to South American temperate forests due to population growth, conversion of native forests to plantations of exotic species and non-sustainable timber harvesting.

Time Toxicity in Wilms Tumor: Quantifying the Burden of Healthcare Interaction in the First Year After Diagnosis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...

Landscape Environmental Monitoring [PDF]

, 2011
Landscape pattern is of primary interest to landscape ecologists and landscape metrics are used to quantify landscape pattern. Calculation of landscape metrics is commonly conducted on completely mapped areas based on remotely sensed data.
