Retrospective image analysis for long‐term demography using Google Earth imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...

Ground‐based robotic remote sensing for standardized biodiversity monitoring in coastal habitats

Remote Sensing in Ecology and Conservation, EarlyView.
Illustrated workflow of the proposed citizen‐to‐robot monitoring pipeline: (i) expert‐validated citizen observations are translated into AI models, (ii) deployed on a ground‐based robotic platform for proximal sensing of coastal dune habitats, (iii) enabling standardized detection of ecological targets (e.g., Pancratium maritimum & Brithys crini), and (

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

Behavior of manufactured sand and recycled coarse aggregate concrete‐filled steel tubular stub columns with circular section

Structural Concrete, EarlyView.
Abstract Accelerated urbanization has intensified environmental concerns due to excessive natural resource consumption and construction waste generation. Circular concrete‐filled steel tube (CFST) columns incorporating manufactured sand recycled coarse aggregate (MS‐RCA) concrete have emerged as an innovative composite element offering notable ...

Fungal endophyte and nitrogen enrichment alter functional traits and productivity in a dominant grass

Ecosphere
Global change factors, such as anthropogenic nitrogen (N) enrichment, have been shown to have diverse and widespread effects on plants and ecosystem functioning, including effects on intraspecific trait variation.

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Vegetated dunes and barchan dune fields

, 2007
Desertifikation steht in enger Beziehung zu aeolischem Sedimenttransport, einschliesslich der Bildung, Evolution und Bewegung von Sanddünen. Sandduenen bewegen sich in riesigen Clustern von tausenden von Dünen unter einer komplexen internen Dynamik, welche ihre Größe und räumliche Verteilung bestimmt.

Shrub encroachment influences root traits and mycorrhization in subalpine grasslands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Shrub encroachment into grasslands modifies ecosystem functions, species composition and soil properties. However, knowledge about its detailed below‐ground effects and specifically on concurrent changes in root traits and mycorrhizal associations is missing. We studied

Fine Sediment in Mixed Sand‐Silt Environments Impacts Bedform Geometry by Altering Sediment Mobility

Water Resources Research
Geometric characteristics of subaqueous bedforms, such as height, length and leeside angle, are crucial for determining hydraulic form roughness and interpreting sedimentary records.

Population structure of Clusia criuva Cambess. (Clusiaceae) and spatial relationship to bromeliads at Parque Municipal das Dunas da Lagoa da Conceição, Florianópolis, SC [PDF]

Biotemas, 2008
“Restinga” habitats present many stressful conditions for plant establishment. Clusia criuva occurs in these habitats, including dune fields, and for this reason the Parque Municipal das Dunas da Lagoa da Conceição, Florianópolis, Santa Catarina State ...
