Spatio-temporal morphological variability of a tropical barrier island derived from the Landsat collection

open access: yesFrontiers in Remote Sensing, 2023
Barrier islands are low-lying elongated, narrow sandy deposits, usually parallel to the coastline, separated from the continent by a lagoon. Due to their low elevation above sea level, barrier islands are environments susceptible to drastic morphological

Managing tourism on Green Island, Great Barrier Reef Marine Park: conservation, commerce and compromises [PDF]

open access: yes, 2011
[Introduction]: This chapter reviews the environmental management of tourism on Green Island a coral cay located 45 minutes from Cairns in Tropical North Queensland, Australia. This 12-hectare coral cay is the single most visited destination on the Great

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

A checklist of dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) associated with the Vypin-Kadamakkudy Barrier Island System, Kerala, India

open access: yesJournal of Asia-Pacific Biodiversity, 2023
Barrier islands are one of the most dynamic ecosystems that are constantly changing with waves, wind, tidal energies, and so on. These islands are placed parallel to the shore with gently sloping coastal plains and a moderate tidal range supported by ...

Controlling Grain Growth in Powder Bed Fusion of Yttria‐Stabilized Zirconia Using Femtosecond Lasers: Challenges and Methodological Insights

open access: yesAdvanced Engineering Materials, EarlyView.
Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

Deer do not affect short‐term rates of vegetation recovery in overwash fans on Fire Island after Hurricane Sandy

open access: yesEcology and Evolution, 2019
Coastal resilience is threatened as storm‐induced disturbances become more frequent and intense with anticipated changes in regional climate. After severe storms, rapid recovery of vegetation, especially that of dune‐stabilizing plants, is a fundamental ...

Melanin's Role in Balancing Mechanical Strength and Reproductive Output in Environmentally Stressed Fungal Spores

open access: yesAdvanced Functional Materials, EarlyView.
Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

Islands, Island Studies, Island Studies Journal [PDF]

open access: yes, 2006
Islands are sites of innovative conceptualizations, whether of nature or human enterprise, whether virtual or real. The study of islands on their own terms today enjoys a growing and wide-ranging recognition.

Sedimentary evolution, hydrogeology and geochemistry of a back-barrier sand island : Toorbul, Southeast Queensland [PDF]

open access: yes, 2008
Small back-barrier sand islands are poorly known in terms of hydrogeology and have been overlooked in more extensive studies of coastal groundwater systems that include larger barrier island complexes.

Advances in 3D Bioprinting for Breast Cancer Modeling: Tumor Microenvironment, Metastasis, and Drug Screening

open access: yesAdvanced Healthcare Materials, EarlyView.
Three‐dimensional bioprinting transforms breast cancer modeling from simple constructs into spatially organized, multicellular, perfused, and patient‐derived platforms. This review shows how bioinks, cellular composition, architecture, and flow govern tumor behavior and drug response, while revealing why complexity alone is insufficient without ...
