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.

Diversification across a heterogeneous landscape

open access: yesEvolution, 2016
Adaptation to contrasting environments across a heterogeneous landscape favors the formation of ecotypes by promoting ecological divergence. Patterns of fitness variation in the field can show whether natural selection drives local adaptation and ecotype formation.

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

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.

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.

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.

Seasonality and Landscape Composition Drive the Diversity of Pollen Collected by Managed Honey Bees

open access: yesFrontiers in Sustainable Food Systems, 2022
The western honey bee, Apis mellifera, is the most important and widespread managed pollinator species. Honey bee diet is based on nectar and pollen, and pollen diversity and composition, in particular, affect colony health and fitness.

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 ...

Eye-tracking analysis in landscape perception research : influence of photograph properties and landscape characteristics [PDF]

open access: yes, 2013
The European Landscape Convention emphasises the need for public participation in landscape planning and management. This demands understanding of how people perceive and observe landscapes.
