Content in nine minerals and seven vitamins of rotifers (Brachionus plicatilis) fed commercial diets and two forms of Nannochloropsis oculata

Journal of the World Aquaculture Society
The objective of the present study was to determine the effects of spray‐dried and fresh forms of the microalgae Nannochloropsis oculata and other commonly used commercial diets on vitamin and mineral compositions of rotifer produced under commercial ...

Environmental Risk Assessment and Anti‐Corrosion Efficacy of Safe‐by‐Design Nitrite‐Based Nanomaterials for Maritime Applications

Nano Select, EarlyView.
The environmental behavior and impact of anti‐corrosion nanoadditives, ZnAl‐NO2 and MgAl‐NO2 layered double hydroxides (LDH), are assessed under marine conditions. These nanomaterials show instability in water but exhibit no or low toxicity to most tested marine species.

Larval condition and growth of Sardinella brasiliensis (Steindachner, 1879): preliminary results from laboratory studies [PDF]

, 2003
Brazilian sardine, the most important resource along the southeastern Brazilian coast, presented great variations and declines in its stocks. The main factors contributing to this are: oceanographic structure changes; recruitment failures; excessive ...

Resource quantity affects infection success and impacts of a microsporidian on hosts

Oikos, EarlyView.
Resource quantity in the environment often changes over time and influences the nutritional status of hosts that may encounter parasites. If resource availability significantly alters both infection success and within‐host growth of a parasite, fluctuations in resources may underlie the seasonal disease outbreaks that have been observed for some ...

The enrichment of rotifers (Brachionus plicatilis) and Artemia franciscana with taurine liposomes and their subsequent effects on the larval development of California yellowtail (Seriola lalandi)

, 2016
Taurine is an essential or conditionally essential nutrient for many species of marine fish, especially during early development. There is growing evidence that marine fish larvae benefit from taurine-enriched rotifers; however, it is unknown if larvae ...

Ecosystem size reverses the effect of the spatial coupling between autotrophic and heterotrophic ecosystems

Oikos, EarlyView.
The flow of non‐living resources between autotrophic and heterotrophic ecosystems can impact their ecosystem function. However, ecosystem size is similarly known to influence ecological properties and it is uncertain how the size of coupled ecosystems mediates the effect of resource flows.

Zooplankton-fish interactions in the littoral zone of Nyanza Gulf, Lake Victoria [PDF]

, 1999
Samples of zooplankton and fish were collected from six sampling points in Nyanza Gulf, Lake Victoria in Kenya from June to December 1998, using 76 mu m memo-filament mesh size strainer and an 80 mu m mesh size plankton net.

Factors affecting methylmercury biomagnification by a widespread aquatic invertebrate predator, the phantom midge larvae Chaoborus [PDF]

, 2012
MeHg biomagnification by the phantom midge Chaoborus in relation to MeHg concentrations in their prey and its migratory behavior was investigated in two Canadian Precambrian Shield lakes.

Seasonal variations in planktonic food web structure affect stability by shifting the distribution of energy fluxes

Oikos, EarlyView.
Seasonality in temperate ecosystems shapes species phenology, influencing interactions and food web structure. Variations in species richness and biomass affect trophic interaction strength, a crucial factor for community stability, which can be assessed through energy fluxes – an essential indicator of ecosystem function.

A georeferenced dataset for occurrence records of the phylum Rotifera in Africa

Journal of Limnology, 2023
We report a dataset of all known and published occurrence records of animals of the phylum Rotifera, including Bdelloidea, Monogononta, and Seisonacea (with the exclusion of Acanthocephala) for Africa and surrounding islands and archipelagos.
