The neuroanatomy of Barentsia discreta (Entoprocta, Coloniales) reveals significant differences between bryozoan and entoproct nervous systems

open access: yesFrontiers in Zoology, 2019
Background Entoprocta affinities within Lophotrochozoa remain unclear. In different studies, entoprocts are considered to be related to different groups, including Cycliophora, Bryozoa, Annelida, and Mollusca.

Roles of Carotenoids in Invertebrate Immunology

open access: yesFrontiers in Immunology, 2020
Carotenoids are biologically active pigments that are well-known to enhance the defense and immunity of the vertebrate system. However, in invertebrates, the role of carotenoids in immunity is not clear.

Corazonin Neurons Contribute to Dimorphic Ethanol Sedation Sensitivity in Drosophila melanogaster

open access: yesFrontiers in Neural Circuits, 2022
Exposure to alcohol has multiple effects on nervous system function, and organisms have evolved mechanisms to optimally respond to the presence of ethanol. Sex differences in ethanol-induced behaviors have been observed in several organisms, ranging from

In the sea slug Melibe leonina the posterior nerves communicate stomach distention to inhibit feeding and modify oral hood movements

open access: yesFrontiers in Physiology, 2022
The sea slug Melibe leonina is an excellent model system for the study of the neural basis of satiation, and previous studies have demonstrated that stomach distention attenuates feeding.

Synonymization of two, monotypic black-coral-commensal scale worm genera, Antipathipolyeunoa Pettibone, 1991 and Parahololepidella Pettibone, 1969 (Polynoidae, Aphroditiformia) [PDF]

open access: yesZooKeys, 2023
Parahololepidella Pettibone, 1969 is a polynoid genus commensal with the antipatharian genus Tanacetipathes Opresko, 2001. These scale worms are elongate with numerous segments and small elytra.

Benthic and hyporheic invertebrate community responses to seasonal flow recession in a groundwater-dominated stream [PDF]

open access: yes, 2010
Natural hydrological variability in lotic ecosystems can include prolonged periods of flow recession. A reduction in discharge is accompanied by abiotic changes in benthic and hyporheic habitats, often including reductions in s habitat availability ...

Improvements in operant memory of Aplysia are correlated with age and specific gene expression

open access: yesFrontiers in Behavioral Neuroscience, 2023
The transcription factor Aplysia CCAAT/enhancer binding protein (ApC/EBP) is expressed as an immediate early gene in the cAMP responsive element binding protein (CREB) mediated gene cascade, and it has essential functions in the synaptic consolidation of

Peptide Cotransmitters as Dynamic, Intrinsic Modulators of Network Activity

open access: yesFrontiers in Neural Circuits, 2018
Neurons can contain both neuropeptides and “classic” small molecule transmitters. Much progress has been made in studies designed to determine the functional significance of this arrangement in experiments conducted in invertebrates and in the vertebrate
