Journal of Limnology, 2015 Zooplankton assemblages in neighboring ponds can show important spatial and temporal heterogeneity. Disentangling the influence of regional versus local factors, and of deterministic versus stochastic processes has been recently highlighted in the ...

FINE STRUCTURE OF THE CILIA OF ROTIFERS [PDF]
The Journal of Cell Biology, 1961 The fine structure of the coronal cilia of the rotifer Philodina citrina has been studied in detail. Specimens were fixed with OsO4 and embedded in butyl—methyl methacrylate, Epon 812, or Vestopal and sectioned with a Porter-Blum microtome. The details of structure of the rootlets, basal bodies, basal plates, and free cilia are described.

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state
Journal of Animal Ecology, EarlyView.The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Diversity, 2021 During a survey in 2015, an impressive assemblage of organisms was found in a hypersaline pond of the Messolonghi saltworks. The salinity ranged between 50 and 180 ppt, and the organisms that were found fell into the categories of Cyanobacteria (17 ...

The FEBS Journal, EarlyView.DNA damage in the tardigrade Hypsibius exemplaris elicits distinct cellular outcomes depending on replication status. While non‐replicating cells tolerate genotoxic stress, constitutively replicating cells undergo irreversible replication failure upon DNA damage, leading to loss of tissue homeostasis, fat depletion, sterility, and organismal death ...

Extremely high abundances of Prasiola crispa-associated micrometazoans in East Antarctica
Polar Research, 2022 To elucidate poorly known aspects of the microscopic metazoan distribution in ice-free parts of the Antarctic, we examined samples of the multicellular terrestrial alga Prasiola crispa, collected over the last decade in different parts of continental ...

NIPPON SUISAN GAKKAISHI, 1979 The sterol components of the rotifer, Brachionus plicatilis, the marine type of Chlorella, Chlorella saccharophila, and the baker's yeast, Saccharomyces cerevisie, were investigated by using combined gas-liquid chromatography and mass spectrometry. The rotifer contained 24-methylcholesta-7, 22-dienol as a major sterol (61% of total sterols), and other ...

Journal of Fish Biology, EarlyView.Abstract High‐latitude ecosystems are simultaneously warming and acidifying under ongoing climate change. Arctic cod (Boreogadus saida) are a key species in the Arctic Ocean and have demonstrated sensitivity to ocean warming and acidification as adults and embryos, but their larval sensitivity to the combined stressors is unknown. In a laboratory multi‐

Early‐life temperature drives recruitment success in Eurasian perch (Perca fluviatilis) populations
Journal of Fish Biology, EarlyView.Abstract Interannual fluctuations in the abundance of young‐of‐the‐year (YOY) European perch (Perca fluviatilis) were studied in two large French peri‐alpine lakes using a 12‐year dataset of late summer hydroacoustic surveys. Previous research has highlighted the importance of temperature.

The Desiccation of Rotifers [PDF]
The American Naturalist, 1908 THE general statement of ten found in text-books that "Adult rotifers can survive prolonged desiccation and resume active life when again placed in water," seems to have been mnade without sufficient warrant. While working with the rotifer, Asplancha briiyltizvell ii, my attention was repeatedly called to the fact that when the water became ...
