Ecological benefits of consistent expression of posterolateral spines in Brachionus calyciflorus

open access: yesJournal of Freshwater Ecology, 2022
Plasticity of spine morphology is a universal phenomenon in rotifers. Some Brachionus calyciflorus clones consistently develop two posterolateral spines (PS) with similar length (Type A), but others (Type B) not. The underlying mechanisms remain unknown.

Recent Trends in Live Feeds for Marine Larviculture: A Mini Review

open access: yesFrontiers in Marine Science, 2022
In marine larviculture, farmed larvae mainly rely on the alimentation of a group of small-sized phytoplankton and zooplankton referred to as live feed. Under the diversifying demands of human consumption and ornamental aquarium industry, new species of ...

Automated system of tubular filtration for rotifer production

open access: yesJournal of the World Aquaculture Society, 2022
This study developed an automated filtration system for a selected rotifer, Brachionus ibericus. This system is controlled by a programmable logic controller, and it enables the high‐density cultivation of marine rotifers and the selection of rotifers ...

Whole tissue imaging of cellular boundaries at sub‐micron resolutions for deep learning cell segmentation: Applications in the analysis of epithelial bending of ectoderm

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background To understand cellular morphology, biologists have relied on traditional optical microscopy of tissues combined with tissue clearing protocols to image structures deep within tissues. Unfortunately, these protocols often struggle to retain cell boundary markers, especially at high enough resolutions necessary for precise cell ...
