The concentrations of some essential (Cu, Zn, Se) and some toxicelements (Hg, As) were determined in tissues (liver, kidneys, integument, and muscle) of the endemic cave salamander, Proteus anguinus Laurenti 1768 and Proteus anguinus parkelj ssp.n. captured in the Planina Cave, Kompolje Cave, and Jelševnik, all situated within the Dinaric Karst in Slovenia. The highest amounts of selenium and mercury were found in the liver of Proteus anguinus specimens from all three localities. Some of the… 
Cd, Cu, Zn, Se, and Metallothioneins in Two Amphibians, Necturus maculosus (Amphibia, Caudata) and Bufo bufo (Amphibia, Anura)
TLDR
The results indicate low Cd storage in liver with almost undetectable Cd in liver MT fractions, and associations of selenium observed with Cd and/or Cu (on the tissue and cell level) point to seenium involvement in the detoxification of excessive cadmium and copper through immobilization.
Is trace element concentration correlated to parasite abundance? A case study in a population of the green frog Pelophylax synkl. hispanicus from the Neto River (Calabria, southern Italy)
TLDR
Correlating parasitological and ecotoxicological data showed a strong positive correlation between prevalence and number of parasites with some trace elements such as Mn, Co, Ni, As, Se, and Cd.
Hepatic Alteration of the Egyptian Toad Amietophrynus Regularis, as Biomarker to Environmental Deterioration
TLDR
It is revealed that deterioration of natural habitat of the selected amphibian produced manifested biochemical and histopathological changes in the liver, which confirmed the adequacy of the studied animals as appropriate bioindicator in their habitat.
Heavy metal accumulation in aquatic animals around the gold mine area of Loei province, Thailand
ABSTRACT This research was conducted to assess the water quality and the contamination of heavy metals in water, sediment, fish, and frogs, as well as bioaccumulation factors (BAFs) in fish and frogs
Composition of the cutaneous bacterial community of a cave amphibian, Proteus anguinus
TLDR
The results provide a baseline for future studies on other endangered neotenic salamanders, and despite an indicated functional redundancy, the cutaneous bacteriome of P. anguinus presumably provides protection against invading microbes by occupying the niche, and thus could serve as an indicator of health status.
Environmental DNA in subterranean biology: range extension and taxonomic implications for Proteus
TLDR
A quantitative real time polymerase chain reaction-based environmental DNA (eDNA) approach to detect the presence of Proteus using water samples collected from karst springs, wells or caves is introduced and shows that the eDNA approach is suitable and efficient in addressing questions in biogeography, evolution, taxonomy and conservation of the cryptic subterranean fauna.
High anoxia tolerance in the subterranean salamander Proteus anguinus without oxidative stress nor activation of antioxidant defenses during reoxygenation
TLDR
A high anoxia tolerance in an amphibian at high temperature is described and uncoupling protein (UCP) transcript was for the first time detected, partly sequenced and quantified in amphibian muscles and liver.
Long‐term starvation in cave salamander effects on liver ultrastructure and energy reserve mobilization
TLDR
Biochemical analysis revealed the utilization of stored metabolic reserves in the liver during food deprivation, and in the Proteus liver carbohydrates are maintained in appreciable amounts and this constitutes a very important energy depot, invaluable in the subterranean environment.

TLDR
The paleogeographical and paleoclimatological data, in combination with the physiological requirements of Proteus, strongly suggest that these animals invaded the caves, at least in the NW parts of their ranges, only after the last glaciations within the last 10,000 years.

Studies have been made of the distribution of mercury and its occurrence as methylmercury in the organs of amphibia collected from different sites mainly in Slovenia, Yugoslavia, including the area

TLDR
An allozyme analysis over 40 loci has shown the new dark pigmented taxon to be genetically similar to a white and troglomorphic neighbouring population from Sticna and genetically dissimilar to a geographically more distant population from Postojna.

TLDR
In these patients greatly increased hepatic copper concentrations, approaching 2,000 µg/g dry tissue, cause degeneration of hepatocytes, necrosis and ultimately cirrhosis2,3.

TLDR
It was found that selenium exerted a protective effect against the toxicity of cadmium and mercury through mechanisms still to be unveiled.
