Temporal shifts in kelp forest structure and distribution largely reflect recent ocean warming trends

open access: yesEcography, EarlyView.
Ocean warming is driving the redistribution of species at a global scale. Biogeographic transition zones are hotspots of species range shifts, as both warm‐ and cold‐adapted species are found toward contrasting range edges. While anecdotal evidence suggests some distributional shifts have occurred in the northeast Atlantic, the empirical evidence base ...

Study on the influence of fine particle spatial distribution on the undrained shear properties of coral sand from reef island

open access: yesShuiwen dizhi gongcheng dizhi
Coral sand is a crucial geotechnical material for the construction of islands and reefs in the South China Sea. In many reclamation areas, the particle size distribution of coral sand spans a wide range, encompassing sizes from sand particles to fine ...

Change Detection of Coral Reef Habitat Using Landsat Imagery in Morotai Island North Maluku Province [PDF]

open access: yes, 2014
Scientific information on coral reef habitat changes of Morotai island is very limited to none. This study aimed to detect the change of coral reef habitats between 1996 and 2013, using Landsat imagery integrated with field data in 2012. The research was

Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

open access: yesFlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

Stress-strain model and deformation parameters of K0-consolidated coral sand

open access: yesYantu gongcheng xuebao, 2023
The stress path followed by soil consolidation in the hydraulic filling site where the coral sand is used as the filling materials is characterized by K0-consolidation. In order to investigate the stress-strain behaviors of the K0-consolidated coral sand,

Biogeographic analysis of the Tortugas Ecological Reserve: Examining the refuge effect following reserve establishment [PDF]

open access: yes, 2004
Almost 120 days at sea aboard three NOAA research vessels and one fishing vessel over the past three years have supported biogeographic characterization of Tortugas Ecological Reserve (TER).

Investigating shellfish deposition and landscape history at the Natia Beach site, Fiji [PDF]

open access: yes, 2008
The relationship between environmental variation and subsistence practices is a central point of discussion in much Oceanic archaeology. While human predation can significantly reduce prey populations, environmental variation also contributes to ...

Evaluating the Air Respiratory Capacity of Awaous (Chonophorus) tajasica (Gobiiformes: Oxudercidae): A Morpho‐Functional Study

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
We demonstrated that Awaous tajasica performs facultative air breathing under experimental conditions of dissolved oxygen limitation, retaining air bubbles in the buccal cavity during gill ventilation. Morpho‐functional evidence indicates the use of atmospheric oxygen as a respiratory support under conditions of low water oxygenation.

Performance of a Subgrade-Embankment-Seawall System Reinforced by Drainage PCC Piles and Ordinary Piles Subjected to Lateral Spreading

open access: yesGeofluids, 2023
Coral sand is widely distributed in coastal areas and used as a soil foundation in an increasing number of projects. Historical records show that the liquefaction and lateral spreading of coral sand foundations occurred many times during earthquakes ...
