[Introduction] One of the most influential theories of scientific explanation to have emerged in the past two decades is Salmon's causal/mechanical theory (Salmon 1984). According to this account, scientific explanations describe a network of causal processes and interactions. In this paper, I will use an example from evolutionary biology to argue

Snail “metabolic hormone” and snail parasite metabolism
Comparative Biochemistry and Physiology, 1970Abstract 1. 1. An acetone extract of the liver of the snail Biomphalaria sudanica and tryptamine stimulate oxygen uptake in the daughter sporocysts of an unknown plagiorchioid cercariae. 2. 2. The same extract stimulates oxygen uptake Schistosoma mansoni but does not affect lactic acid production or glucose uptake in these worms. 3.

Snails and snail farming: an introduction for the veterinary profession.
The Veterinary record, 1991In the past veterinary interest in snails has been confined to their role in the transmission of disease; nowadays the trend to keep these animals in captivity--for food, for study, as 'companion animals'--means that the profession is increasingly likely to be consulted about their health, welfare or conservation.

Schistosomiasis from a Snail’s Perspective: Advances in Snail Immunity
Trends in Parasitology, 2017The snail's immune response is an important determinant of schistosome infection success, acting in concert with host, parasite, and environmental factors. Coordinated by haemocytes and humoral factors, it possesses immunological hallmarks such as pattern recognition receptors, and predicted gastropod-unique factors like the immunoglobulin superfamily ...

Fresh water snails as bioindicator for some heavy metals in the aquatic environment
, 2013The aim of this investigation is to study some freshwater snails as bioindicator for heavy metals Cd, Cu and Pb by determining the concentration of these metals in the field water samples and in whole snail tissues.

Peptide neurotoxins from fish-hunting cone snails.
Science, 1985To paralyze their more agile prey, the venomous fish-hunting cone snails (Conus) have developed a potent biochemical strategy. They produce several classes of toxic peptides (conotoxins) that attack a series of successive physiological targets in the ...
