BACKGROUND Several organisms display dormancy and developmental arrest at embryonic stages. Long-term survival in the dormant form is usually associated with desiccation, orthodox plant seeds and Artemia cysts being well documented examples. Several aquatic invertebrates display dormancy during embryonic development and survive for tens or even hundreds of years in a hydrated form, raising the ...

The recent discovery of the production of anti-proliferative aldehydes in a variety of microalgal species has lead to considerable investigation into the effects of these toxins on aquatic invertebrates. Studies have, however, rarely considered the impact pollutants may have on grazer responses to algal toxins. In this study, the acute toxicities of five aldehydes to the rotifer Brachionus plic...

Bu çalışmada, rotifer Brachionus plicatilis kültüründe 2 formüle emülsiyon (Emülsiyon-I ve Emülsiyon-II) 3 farklı ticari ürün (Olio w-3, Red Pepper (n-3) Top Rich) kullanımının popülasyon artışı üzerine etkisi araştırılmıştır. Rotiferler için oluşturulan deneme grupları sırasıyla; DHA-Gold (Kontrol), + Emülsiyon-I (1. Grup), Emülsiyon-II (2. Olio w-3 (3. (4. Rich (5. Grup) olarak belirlenmiştir...

BACKGROUND Rotifers are among the most common non-arthropod animals and are the most experimentally tractable members of the basal assemblage of metazoan phyla known as Gnathifera. The monogonont rotifer Brachionus plicatilis is a developing model system for ecotoxicology, aquatic ecology, cryptic speciation, and the evolution of sex, and is an important food source for finfish aquaculture.
