Bdelloid rotifers revisited [PDF]

open access: yesProceedings of the National Academy of Sciences, 2004
Sexual reproduction is one of the most striking features of the biological world. The great majority of the animals and plants with which we are most familiar reproduce at least part of the time by means of sexual reproduction with meiosis, recombination, and fertilization.

A Checklist of Turkish Rotifers

open access: yesTurkish Journal of Zoology, 2012
In a book chapter containing the first checklist and distribution of Turkish rotifers, published in 1999, were listed 167 taxa. The second checklist, published in 2004, reported 229 rotifer taxa in Turkey. During the 7 years since this checklist process, many studies have been carried out and we have prepared a new checklist of Turkish rotifers in the ...

Rotifers: Exquisite Metazoans [PDF]

open access: yesIntegrative and Comparative Biology, 2002
Rotifers comprise a modestly sized phylum (≈1,850 species) of tiny (ca. 50-2,000 μm), bilaterally symmetrical, eutelic metazoans, traditionally grouped within the pseudocoelomates or Aschelminthes. These saccate to cylindrically shaped protostomes possess three prominent regions (corona, trunk, foot).

Effects of Different Co-Feeding Protocols on the Early Weaning of Flathead Grey Mullet (Mugil cephalus) Larvae

open access: yesAnimals, 2023
The sustainable expansion of aquaculture relies on a sufficient supply of eggs and larvae, which are the first step of life cycle management. However, marine fish larval rearing generally depends on live feed production, which needs additional facilities

L-carnitine can promote the growth performance of rotifers (Brachionus rotundiformis) by improving their feeding behavior and nutrient composition

open access: yesAquaculture Reports
Rotifer are important food resources in aquaculture hatcheries, and several studies have shown that L-carnitine (LC) can promote the growth performance of rotifers.

Dietary Value of Waste-Fed Rotifer Brachionus rotundiformis on the Larval Rearing of Japanese Whiting Sillago japonica [PDF]

open access: yesE3S Web of Conferences, 2020
Live food resources are useful for larval fish rearing. However, production of sufficient live food resources is expensive. This study employed a cost-effective rotifer culture technique using fish waste diet (FWD) and investigate the effect of the FWD ...

The Impact of Two Different Cold-Extruded Feeds and Feeding Regimens on Zebrafish Survival, Growth and Reproductive Performance

open access: yesJournal of Developmental Biology, 2018
Zebrafish (Danio rerio) is one of the top model organisms used in biomedical research. Therefore, it is fundamental that zebrafish facilities continuously improve husbandry methods to provide fish with the best physiological and welfare conditions that ...

Zebrafish inversin mutants develop scoliosis in the absence of laterality defects

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Human mutations in INVERSIN are associated with nephronophthisis, variable penetrance of situs inversus and congenital heart disease. Inversin has been shown to localize to cilia and many of the patient phenotypes are attributed to disrupted cilia function.

Growth and toxicity of Halomicronema metazoicum (Cyanoprokaryota, Cyanophyta) at different conditions of light, salinity and temperature

open access: yesBiology Open, 2019
Cyanobacteria may live in the water column and in the benthos of aquatic environments, or be symbionts of other organisms, as in the case of Phormidium-like cyanobacteria, known to influence the ecology of freshwater and marine ecosystems.

Warming modifies trophic impacts of invading shrimp with impact varying among primary producers

open access: yesOikos, EarlyView.
Environmental change drivers, such as climate change and species invasions, can disrupt biological networks and weaken ecosystem stability. Acting together, these drivers may interact and alter the effects on the ecosystem. However, few studies have examined the interactive effects of climate change and species invasions, particularly in aquatic ...
