The Lymnaea Cardioexcitatory Peptide (LyCEP) Receptor: A G-Protein–Coupled Receptor for a Novel Member of the RFamide Neuropeptide Family [PDF]
, 1998 A novel G-protein–coupled receptor (GRL106) resembling neuropeptide Y and tachykinin receptors was cloned from the molluscLymnaea stagnalis. Application of a peptide extract from the Lymnaea brain to Xenopus oocytes expressing GRL106 activated a calcium ...

Insect Conservation and Diversity, EarlyView.Sheep and cattle grazing significantly shape ant and ground beetle species composition in Mediterranean cork oak woodlands, promoting higher diversity by increasing habitat heterogeneity. Ground beetles and ants reflect changes in grazing regimes, with sheep‐grazed areas showing the highest diversity, highlighting their utility in ecosystem monitoring.

Electrophysiological Organization of the Eye of Aplysia [PDF]
, 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 ...

Event Timing in Associative Learning [PDF]
, 2012 Associative learning relies on event timing. Fruit flies for example, once trained with an odour that precedes electric shock, subsequently avoid this odour (punishment learning); if, on the other hand the odour follows the shock during training, it is ...

Evolutionary legacies structure the geography of seagrass traits across the world's oceans
New Phytologist, EarlyView.Summary Traits modulate species' ability to track shifts in climate, yet the extent to which traits have been shaped by the contemporary environment and/or historical processes remains poorly understood. Here, we fill this gap for the world's seagrasses, habitat‐forming species that provide critical ecosystem services.

A unified approach to model peripheral nerves across different animal species [PDF]
PeerJ, 2017 Peripheral nerves are extremely complex biological structures. The knowledge of their response to stretch is crucial to better understand physiological and pathological states (e.g., due to overstretch).

Origin and diversification of steroids: Co-evolution of enzymes and nuclear receptors [PDF]
, 2010 Recent sequencing of amphioxus and sea urchin genomes has provided important data for understanding the origins of enzymes that synthesize adrenal and sex steroids and the receptors that mediate physiological response to these vertebrate steroids ...

Boletim do Instituto Oceanográfico, 1957 De Aplysia cervina (Dall & Simpson 1901) conhecia-se, do Brasil, um exemplar de Maceio. Mais um, quase maduro, foi colhido no eulitoral da ilha de Sao Sebastiao. Enquanto vivente, tinha comprimento de 10 cm. A especie distingue-se, de A. brasiliana, pelas manchas escuras redondas (Fig. 1), pela forma das mandibulas (Fig. 4) e dos bastonetes (Fig.

Characterization of Aplysia carboxypeptidase E
FEBS Letters, 1997 Carboxypeptidase E (CPE) is involved in the biosynthesis of peptide hormones and neurotransmitters. To determine whether a recently reported Aplysia californica cDNA encodes a CPE‐like enzyme, this cDNA was expressed in the baculovirus system. The Aplysia CPE is optimal at pH 5.5–6.5 and is inhibited by chelating agents and by the sulfhydryl reagent p ...
