Differential Contribution of Subunit Interfaces to α 9 α 10 Nicotinic Acetylcholine Receptor Function [PDF]

open access: yes, 2017
Nicotinic acetylcholine receptors can be assembled from either homomeric or heteromeric pentameric subunit combinations. At the interface of the extracellular domains of adjacent subunits lies the acetylcholine binding site, composed of a principal ...

How do parasites and predators choose their victim? A trade‐off between quality and vulnerability across antagonistic interactions

open access: yesBiological Reviews, Volume 100, Issue 5, Page 2099-2115, October 2025.
ABSTRACT From blood‐sucking lice and food‐stealing gulls to pandemic‐inducing viruses and egg‐eating snakes: parasites and predators are ubiquitous in shaping ecology and evolution. Fundamental to these interactions is the way in which parasites and predators choose their victim. Here, I argue that a trade‐off between host quality and vulnerability can

Effects of Ingestion of Lithic Particles on Growth of the Apple Snail Pomacea canaliculata (Caenogastropoda, Ampullariidae) [PDF]

open access: yes, 2016
Lithic particles are a common feature in the digestive tract of freshwater snails. Their role in the digestive processes has been demonstrated in some microphytophagous and detritivorous species, as they enhance growth, assimilation and reproduction.

Diplostomum‐Induced Sac Formation in Lenses of Ameiurus Bullheads: A Host Defence Response?

open access: yesJournal of Fish Diseases, Volume 48, Issue 10, October 2025.
ABSTRACT Trematodes of the genus Diplostomum (Diplostomidae) are widely distributed and significant fish pathogens known for causing a range of negative effects. Any mechanism that protects the host from the parasite thus represents an evolutionary advantage.

Warming strengthens food web effects of predator phenotypic variation

open access: yesFunctional Ecology, Volume 39, Issue 9, Page 2284-2299, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Intraspecific variation modifies ecological processes and ecosystem functioning. Still, we know relatively little of how the nature and strength of ecosystem effects caused by intraspecific variation may interact with climate change.

Sensibilité de Lymnaea natalensis à quelques extraits de plantes, à l'âge de deux semaines

open access: yesRevue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1989
Le pouvoir molluscicide de 17 extraits de plantes nigérianes a été évalué sur des Lymnaea natalensis Krauss de 2 semaines (méthode par extraction aqueuse sans évaporation). Cinq extraits ont été inactifs ; en revanche les extraits de Balanites aegytiaca,

Menin: a tumor suppressor that mediates postsynaptic receptor expression and synaptogenesis between central neurons of Lymnaea stagnalis. [PDF]

open access: yesPLoS ONE, 2014
Neurotrophic factors (NTFs) support neuronal survival, differentiation, and even synaptic plasticity both during development and throughout the life of an organism. However, their precise roles in central synapse formation remain unknown.

Spatio-temporal co-occurrence of alien and native molluscs : a modelling approach using physical-chemical predictors [PDF]

open access: yes, 2017
The invasion of alien species can have serious economic and ecological impacts. Ecologically, invasions often lead to an increased rate of native species replacement and decreased biodiversity.
