Integrated Biomarker Response in Signal Crayfish Pacifastacus Leniusculus Exposed to Diphenhydramine

SSRN Electronic Journal, 2022
Diphenhydramine (DPH) is a pharmaceutical with multiple modes of action, primarily designed as an antihistamine therapeutic drug. Among antihistamines, DPH is a significant contaminant in the environment, frequently detected in surface waters, sediments, and tissues of aquatic biota.

Signal crayfish as vectors in crayfish plague in Britain

Aquaculture, 1990
Abstract An outbreak of crayfish plague (caused by the fungus Aphanomyces astaci) is described in white-clawed crayfish, Austopotamobius pallipes, in enclosed pond culture in an area of England from which no disease outbreaks have yet been reported.

Visceral Afferent Signals in the Crayfish Stomatogastric Ganglion

Journal of Experimental Biology, 1966
ABSTRACT The crayfish stomatogastric ganglion (SG) contains about twenty-five neurone somata; it supplies motor innervation for the anterior gut, and receives afferent input from mechanoreceptors associated with the stomach. Its proximal branches respond to normal stomach contractions with a complex, patterned, centrally directed ...

Brain Electrical Signals in Unrestrained Crayfish

2002
The electrical activity from the brain of vertebrates and some mollusks (octopus and cuttlefish; Bullock 1984) is dominated by slow components in the range 0 to 30 Hz and fast events such as spikes are seen by special effort. In contrast, electrical activity from the brain of several invertebrates such as crayfish, earthorm, slug and grasshopper, is ...

Properties of glutaminase of crayfish CNS: implications for axon–glia signaling

Neuroscience, 2002
Glutaminase of crayfish axons is believed to participate in recycling of axon-glia signaling agent(s). We measured the activity and properties of glutaminase in crude homogenates of crayfish CNS, using ion exchange chromatography to separate radiolabeled product from substrate.

Signal crayfish, Pacifastacus leniusculus, as a vector for Psorospermium haeckeli to noble crayfish, Astacus astacus

Aquaculture, 1996
Abstract As part of investigations of the ecological impact and transmission of the crayfish parasite Psorospermium haeckeli , a laboratory experiment was performed where noble crayfish, Astacus astacus , and signal crayfish, Pacifastacus leniusculus , from populations in which P.

Does the introduced signal crayfish occupy an equivalent trophic niche to the lost native noble crayfish in boreal lakes?

Biological Invasions, 2014
The introduced North-American signal crayfish (Pacifastacus leniusculus) has become widespread throughout Europe where it has often replaced the native noble crayfish (Astacus astacus). The impact of this replacement on ecosystem processes in boreal lakes is still largely unknown. We compared the trophic niches of these two crayfish species in 16 small

Numerous population crashes of wild signal crayfish (Pacifastacus leniusculus) in southern Finland

Freshwater Crayfish, 2014
The alien signal crayfish (Pacifastacus leniusculus) was introduced into Finland, and then more broadly in Europe, with the expectation that it would be a suitable substitute for the native crayfish that was eradicated by crayfish plague (Aphanomyces astaci) epidemics.
