Learning processes in elementary nervous systems§ [PDF]

open access: yesJournal of Integrative Neuroscience, 2020
Invertebrate animal models show simple behaviors supported by neural circuits easily accessible for experimentation and yet complex enough to provide necessary information on the cellular and molecular mechanisms that govern the vertebrate nervous system'

Assessing Magnesium Chloride as a Chemical for Immobilization of a Symbiotic Jellyfish (Cassiopea sp.)

open access: yesFrontiers in Marine Science, 2022
Immobilization of marine invertebrates for research purposes has been commonly used and is often necessary to obtain high-quality findings. Despite these approaches being standard procedures, they can affect the specimens, and their responses as well ...

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 ...

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.

Single-cell RNA sequencing analysis of shrimp immune cells identifies macrophage-like phagocytes

open access: yeseLife, 2022
Despite the importance of innate immunity in invertebrates, the diversity and function of innate immune cells in invertebrates are largely unknown. Using single-cell RNA-seq, we identified prohemocytes, monocytic hemocytes, and granulocytes as the three ...

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.

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

Using citizen science to survey the invertebrate communities on reclaimed collieries [PDF]

open access: yes, 2011
Public participation in scientific research, or ‘citizen science’, is becoming more widely used, as the benefits of this research model are realised. This study recruited and trained volunteers to survey invertebrates using a modified citizen science ...
