Possible role of microtubules in vesicular transport of matrix protein during sea urchin larval biomineralization

Developmental Dynamics, EarlyView.
Abstract Background Biomineralization is a vital biological process through which organisms produce mineralized structures such as shells, skeletons, and teeth. Microtubules are essential for biomineralization in various eukaryotic species; however, their specific roles in this process remain unclear.

Developing a macroecology for human‐altered ecosystems

Ecography, EarlyView.
Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

A Multi‐Timescale EnOI‐Like High‐Efficiency Approximate Filter for Coupled Model Data Assimilation

Journal of Advances in Modeling Earth Systems, 2019
Because it uses a set of model integrations to simulate the temporally varying background probability distribution function and implement Bayes' theorem, the ensemble Kalman filter (EnKF), which produces an optimal data assimilation solution that ...

Trends in marine species distribution models: a review of methodological advances and future challenges

Ecography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Photoelectrochemical Charge Excitation Enhancement by Triboelectric Nanogenerator for High‐Efficiency Self‐Powered Anticorrosion

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The synergy of solar and mechanical energy enables a self‐powered photoelectrochemical cathodic protection system, which enhances carrier separation for efficient and sustainable anticorrosion. Harnessing the synergy of solar and mechanical energy presents a potential strategy for high‐efficiency photoelectrochemical cathodic protection.

Coupled echosounder and Doppler profiler measurements in the Strait of Gibraltar

Scientific Reports
Long time series of velocity profiles collected by up-looking acoustic profilers in the westernmost sill of the Strait of Gibraltar show an unexpected pattern in the deepest ∼80 m of the water column, consisting in an appreciable diurnal weakening of the

Lithology, monsoon and sea-surface current control on provenance, dispersal and deposition of sediments over the Andaman continental shelf

Frontiers in Marine Science, 2016
Sediments deposited on the Northern and Eastern Andaman Shelf along with a few sediments from the Irrawaddy and the Salween Rivers are studied for their elemental, Sr and Nd concentrations and their isotope composition to identify their sources ...

Projected Atlantic overturning slow-down is to be compensated by a strengthened South Atlantic subtropical gyre

Communications Earth & Environment, 2023
Large ensemble simulations project an intensification of the South Atlantic subtropical gyre with reduced water supply to the North Atlantic due to a weakening of the Atlantic meridional overturning circulation and changes in atmospheric forcing.
