Comparing the Last Interglacial (MIS 5e) with the present interglacial period (MIS 1) using a multidimensional functional diversity analysis: The marine molluscs from Santa Maria Island (Azores Archipelago, central Atlantic) as a case study

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Marine fossil records hold outstanding importance for ecological, evolutionary and biogeographical studies. Santa Maria Island in the Azores Archipelago (central Atlantic) features a remarkable marine fossil record spanning from the Pliocene to recent times.

Comparing non‐staining methods with Mutvei's solution to visualize growth increments in short‐lived intertidal marine gastropod shells

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Mutvei's solution is a widely utilized standard staining method for revealing growth increments in biogenic carbonates; however, it is a slightly toxic, destructive approach with varying success across species groups. Therefore, there has been growing interest in finding non‐toxic, less destructive, and straightforward alternative techniques ...

Comparison of optical and digital techniques for light microclimate assessment in the Paneveggio Forest, Trentino, Italy

open access: yesForest@, 2006
Hemispherical photography is a widely used tool for the indirect estimation of forest light environment and quantification of canopy openness, LAI, and direct and diffuse canopy light transmittance.

Perforation resistance of aluminum/polyethylene sandwich structure [PDF]

open access: yes, 2016
© 2016 Elsevier Ltd. Ballistic tests were performed on two types of polyethylene core sandwich structures (AA6082/LDPE/AA6082 and AA6082/UHMWPE/AA6082) to investigate their perforation resistance.

Highly Durable and Uniform Structural Coloration via Spray‐Coated Organic Mie Resonators Randomly Distributed in Three Dimensions

open access: yesLaser &Photonics Reviews, EarlyView.
This study demonstrates uniform, durable non‐iridescent structural coloration using polystyrene nanoparticles randomly embedded in a thick sodium silicate with absorptive additives. By suppressing the effects of the structure factor and multiple scattering, this approach achieves uniform coloration from the backscattering.

Veronica paczoskiana is no more than a pine forest ecotype of V. spicata that evolved independently in forest‐steppes of Ukraine and the Altai region

open access: yesNordic Journal of Botany, EarlyView.
The Eurasian steppe area has been a dynamic vegetation biome during the Pleistocene with its repeated cycles of forest advances and retreats. Such a scenario allows the evolution of ecotypes at the ecotone with the potential for parallel evolution in different parts of the distribution area.

Usage of LiDAR data for leaf area index estimation [PDF]

open access: yes, 2014
Leaf area index (LAI) can be measured either directly, using destructive methods, or indirectly using optical methods that are based on the tight relationship between LAI and canopy light transmittance.

Micromorpho‐anatomical studies on the leaves and woods of Turkish Daphne (Thymelaeaceae) taxa

open access: yesNordic Journal of Botany, EarlyView.
The identification of Daphne taxa is difficult because of the lack of available morphological characteristics. Here, we aimed to describe leaf and wood micromorpho‐anatomical characteristics of native Turkish Daphne taxa (D. glomerata, D. gnidioides, D. mezereum, D. mucronata, D. oleoides subsp. kurdica, D. pontica and D.
