Advancing Texture Metrics to Model Landscape Heterogeneity [PDF]

open access: yesIGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
We advance methods to study landscape heterogeneity and assess the suitability of these methods to detect boundary regions between land cover types. We employ 2nd-order texture metrics on continuous and on discrete vegetation data in North Eurasia and on a smaller region therein.

Effects of compositional heterogeneity and spatial autocorrelation on richness and diversity in simulated landscapes

open access: yesEcology and Evolution, 2023
Landscape structure plays a key role in mediating a variety of ecological processes affecting biodiversity patterns; however, its precise effects and the mechanisms underpinning them remain unclear.

Comparison of Various Annual Land Cover Datasets in the Yellow River Basin

open access: yesRemote Sensing, 2023
Accurate land cover (LC) datasets are the basis for global environmental and climate change studies. Recently, numerous open-source annual LC datasets have been created due to advances in remote sensing technology.

Biodiversity as spatial insurance in heterogeneous landscapes [PDF]

open access: yesProceedings of the National Academy of Sciences, 2003
The potential consequences of biodiversity loss for ecosystem functioning and services at local scales have received considerable attention during the last decade, but little is known about how biodiversity affects ecosystem processes and stability at larger spatial scales.

Selecting Graph Metrics with Ecological Significance for Deepening Landscape Characterization: Review and Applications

open access: yesLand, 2022
The usual approaches to describing and understanding ecological processes in a landscape use patch-mosaic models based on traditional landscape metrics. However, they do not consider that many of these processes cannot be observed without considering the

Assessment of the quality of the terrestrial habitat of the threatened dragonfly, Sympetrum depressiusculum (Odonata: Libellulidae)

open access: yesEuropean Journal of Entomology, 2016
The majority of the conservation strategies for threatened dragonflies are designed to protect only their aquatic habitats. Sympetrum depressiusculum is a species threatened not only by the destruction of its aquatic habitats but also by its association ...

Land-use diversity within an agricultural landscape promotes termite nutrient cycling services in a southern African savanna

open access: yesGlobal Ecology and Conservation, 2020
Soil macrofauna provide key supporting ecosystem services by transporting nutrients against physical and chemical gradients. In the semi-arid savannas of southern Africa, termites are the dominant macrofauna whose foraging activities increase nutrient ...

Why Do Agroforestry Systems Enhance Biodiversity? Evidence From Habitat Amount Hypothesis Predictions

open access: yesFrontiers in Ecology and Evolution, 2022
Considering the present ecological crisis, land use-biodiversity relationships have become a major topic in landscape planning, ecosystem management and ecological restoration.

Landscape variation in soil carbon stocks and respiration in an Arctic tundra ecosystem, west Greenland

open access: yesArctic, Antarctic, and Alpine Research, 2018
The magnitude and acceleration of carbon dioxide emissions from warming Arctic tundra soil is an important part of the Region’s influence on the Earth’s climate system.

Heterogeneity in African savanna elephant distributions and their impacts on trees in Kruger National Park, South Africa

open access: yesEcology and Evolution, 2021
Though elephants are a major cause of savanna tree mortality and threaten vulnerable tree species, managing their impact remains difficult, in part because relatively little is known about how elephant impacts are distributed throughout space.
