Electrophysiological Organization of the Eye of Aplysia [PDF]

open access: yes, 1969
The eye of Aplysia californica was studied by electrophysiological and histological methods. It has a central spheroidal lens which is surrounded by a retina composed of several thousand receptor cells which are replete with clear vesicles, pigmented ...

Taxonomy and palaeoecology of continental Gastropoda (Mollusca) from the Late Pleistocene mammoth-bearing site of Bullendorf in NE Austria [PDF]

open access: yes, 2018
We present a taxonomic and palaeoecological analysis of a continental mollusc fauna from a mammoth-bearing succession near Bullendorf in Lower Austria.

Reversal of age-related learning deficiency by the vertebrate PACAP and IGF-1 in a novel invertebrate model of aging: the pond snail (Lymnaea Stagnalis) [PDF]

open access: yes, 2014
With the increase of life span, nonpathological age-related memory decline is affecting an increasing number of people. However, there is evidence that age-associated memory impairment only suspends, rather than irreversibly extinguishes, the intrinsic ...

Nociceptive Biology of Molluscs and Arthropods: Evolutionary Clues About Functions and Mechanisms Potentially Related to Pain

open access: yesFrontiers in Physiology, 2018
Important insights into the selection pressures and core molecular modules contributing to the evolution of pain-related processes have come from studies of nociceptive systems in several molluscan and arthropod species.

Effect of cadmium on cytosine hydroxymethylation in gastropod hepatopancreas [PDF]

open access: yes, 2017
5-Hydroxymethylcytosine (5hmC) is an important, yet poorly understood epigenetic DNA modification, especially in invertebrates. Aberrant genome-wide 5hmC levels have been associated with cadmium (Cd) exposure in humans, but such information is lacking ...

Students' knowledge on the African giant mollusk Achatina fulica in a public school in the Recife metropolitan region [PDF]

open access: yesBiotemas, 2007
The African giant mollusk Achatina fulica Bowdich, 1822 was introduced into Brazil in 1988 as a substitute for the European escargot Helix sp. This action did not induce the expected results and the gastropod has become an invasive species according to ...

Octopamine increases the excitability of neurons in the snail feeding system by modulation of inward sodium current but not outward potassium currents [PDF]

open access: yes, 2005
Background: Although octopamine has long been known to have major roles as both transmitter and modulator in arthropods, it has only recently been shown to be functionally important in molluscs, playing a role as a neurotransmitter in the feeding network

From sea to land and beyond : new insights into the evolution of euthyneuran Gastropoda (Mollusca) [PDF]

open access: yes, 2008
Background The Euthyneura are considered to be the most successful and diverse group of Gastropoda. Phylogenetically, they are riven with controversy.

Pressurized plankton observatory offers a new window into deep‐sea larval behavior

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract The High‐Pressure Plankton Observatory (HiPPO) is designed to quantify motions of zooplankton for behavioral study, including swimming and metabolic responses to environmental perturbations. It builds on prior chamber designs while filling gaps in capability for resolving orientation of small (< 1 mm) plankton, tracking their movements over ...

Evolution der Cephalic Sensory Organs innerhalb der Opisthobranchia [PDF]

open access: yes, 2008
Das Ziel der vorliegenden Doktorarbeit war es, die Evolution der Kopfsinnesorgane der Opisthobranchia zu rekonstruieren. Bei den Opisthobranchia handelt es sich um eine äußerst diverse Gruppe überwiegend mariner Gastropoden innerhalb der Euthyneura.
