RELATIONS BETWEEN NERVES AND CILIA IN CTENOPHORES [PDF]

open access: yesAmerican Zoologist, 1965
Waves of excitation, visible as ciliary waves, pass along the elongated cells of the ciliated grooves to the comb plates. The frequency of waves is controlled by the loading of the statolith on the balancer cilia, which stand at the head of the grooves. They are primitive mechanoreceptor cilia.

Long-term changes of physicochemical parameters and benthos in Lake Qarun (Egypt): Can we make a correct forecast of ecosystem future?

open access: yesKnowledge and Management of Aquatic Ecosystems, 2016
Biotic changes and a salinity increase (from 13 to 40 g.L-1) occurred in Lake Qarun (Egypt) since 1901. Was salinity increasing a cause of observed biotic changes? To answer this question we used benthos as a model group.

Diverse RNA interference strategies in early-branching metazoans

open access: yesBMC Evolutionary Biology, 2018
Background Micro RNAs (miRNAs) and piwi interacting RNAs (piRNAs), along with the more ancient eukaryotic endogenous small interfering RNAs (endo-siRNAs) constitute the principal components of the RNA interference (RNAi) repertoire of most animals.
