The Calabrian Alpine newt (Ichthyosaura alpestris inexpectata) is a glacial relict with small and extremely localised populations in the Catena Costiera (Calabria, Southern Italy) and is considered to be “Endangered” by the Italian IUCN assessment. Climate-induced habitat loss and recent fish introductions in three lakes of the Special Area of Cons...

Climate and land cover changes are the two most important stressors causing the decline of amphibians’ populations worldwide. Within the Mediterranean area, one of the global biodiversity hotspots, the endemic Italian yellow-bellied toad (Bombina pachypus) suffered the same fate, as the decreases and local extinctions proved over time. Since the ne...

Ichthyosaura alpestris inexpectata (Dubois & Breuil, 1983) è un relitto glaciale presente con popolazioni piccole e isolate in cinque località nella Catena Costiera settentrionale (Giacoma et al., 1988; Lanza et al., 2007). Il tritone calabro rappresenta quindi un unicum di elevato valore biogeografico e conservazionistico. Tutte le località di pre...

The Calabrian Peninsula (Southern Italy) has acted as a glacial refugium and is now considered a hotspot for the genetic diversity of several species. Even if it hosts the highest diversity of many Italian endemic amphibian species, the distribution of some of these needs an update to address conservation measures. We took advantage of a vast datas...

Monograph in two volumes that contains factsheets and information on all the sites of the Natura 2000 network in Calabria, accompanied by the floristic and faunal information used for the Fourth European Report on the state of the Natura 2000 network. This work is proposed as a popularizing tool, as a basis for environmental education projects, but...

Tebuconazole (TBZ), an azole pesticide, is one of the most frequently detected fungicides in surface water. Despite its harmful effects, mainly related to endocrine disturbance, the consequences of TBZ exposure in amphibians remain poorly understood. Here, we investigated the adverse and delayed effects of TBZ chronic exposure on a native anuran sp...

Despite Calabria represents an interesting study area due to its geographic position, nothing is known of the presence of sharks and rays in this region. Data presented in this work come from nineteen years of opportunistic fishing surveys (from 2000 to 2019). Our data shows that 53 species of elasmobranchs are present in Calabrian seas: 30 of thes...

Lead is one of the most alarming toxic pollutants for the environment due to its acute toxicity and high bioaccumulation tendency. Despite legislative efforts, world lead production has more than doubled since the early 1970s to 2016. Due to extensive exploitation and human activity, the coastal and estuarine regions belong to marine environments t...

We provide comparative and updated staging tables for the larvae of three syntopic newt species–Triturus carnifex, Lissotriton italicus and Ichthyosaura alpestris inexpectatus –living in Calabria. A detailed description, stage by stage, of the full larval period until completion of metamorphosis is furnished, accompanied by photographic tables of t...

The paper confirms the presence of Alopias superciliosus in the Tyrrhenian Sea, giving useful information for a species assessed as "vulnerable" worldwide and "data deficient" for the Mediterranean Sea by IUCN. In the stomach of this shark, 25 specimens of Pseudophyllidea, 4 of Trypanorhyncha and 3 of Anisakis spp. were found. In the gut, the prese...

Amphibian habitats are easily contaminated by several pollutants, and in agricultural landscapes the likely exposure scenario is represented by pesticides. Many of these substances are known or suspected to act as endocrine disrupting chemicals (EDCs). The goal of the present study was to assess the effects of pyrimethanil, a common-used but also o...

Mercury (Hg) is a highly hazardous pollutant widely used in industrial, pharmaceutical and agricultural fields. Mercury is found in the environment in several forms, elemental, inorganic (iHg) and organic, all of which are toxic. Considering that the liver is the organ primarily involved in the regulation of metabolic pathways, homeostasis and deto...

Over the last few years, the hazards associated with the extensive use of fungicides have become an issue of great concern but, at present, the effects of these substances on amphibians remain poorly understood. The goal of the present study was to assess the effects of two commonly used fungicides, tebuconazole and pyrimethanil, on Italian Tree Fr...

We examined, from a morphological and ultrastructural point of view, the liver of the Italian newt (Lissotriton italicus), under basal conditions and after exposure to nonylphenol ethoxylates (NPEs). Nonylphenol ethoxylates are surfactants widely used in a variety of industrial and agricultural processes that may pose a significant risk to aquatic...

The nesting ecology of the slider turtle Trachemys scripta elegans was studied in Angitola Lake, a natural protected area in Calabria (Southern Italy). During 2008-2010, data were collected based on 1081 egg shells from 250 nests. The average number of egg shells per nest was 4.3 (min-max = 1-16) and the clutch size increased from 2008 to 2010. Two...

During amphibian metamorphosis, modifications of several important body systems take place involving different molecular mechanisms driving, among other, cell differentiation, cell-cell adhesion, and extracellular matrix turnover. Amphibians have been used as a classic model to investigate organs remodelling, including the skin; however, previous s...

Endosulfan is a persistent organic pollutant (POP) that has lethal and sublethal effects on non-target organisms, including amphibians. In a laboratory study, we investigated direct and post-exposure effects of endosulfan on Bufo bufo tadpoles. For this purpose we exposed the tadpoles to a single short-term contamination event (96h) at an environme...

Freshwater habitats are globally threatened by human-induced secondary salinization. Amphibians are generally poorly adapted to survive in saline environments. We experimentally investigated the effects of chronic exposure to various salinities (5%, 10%, 15%, 20%, 25%, 30% and 35% seawater, SW) on survival, larval growth and metamorphosis of tadpol...

Endosulfan is an organochlorine pesticide that was recently labeled as a persistent organic pollutant, but it is still widely employed, particularly in developing countries. The goal of this study is to evaluate the acute (LC(50)) and chronic effects (developmental and behavioural traits) of this insecticide on Rana dalmatina tadpoles after exposur...

The goal of this study is to evaluate the acute and chronic effects of this insecticide on Rana dalmatina tadpoles. To assess the sensitivity of this species, the...

Endosulfan sprayed on agricultural fields accumulates in temporary pools due to surface runoff or sediment transport and may result in high water concentrations in spring and summer, coinciding with breeding and crucial stages of amphibian larval development. In the present study, Bufo bufo tadpoles were exposed to three different concentrations of...

An investigation was conducted to determine the effects of the heavy metal, cadmium (Cd), on the gills of the teleost fish, Thalassoma pavo Linnaeus, 1758. The fishes were exposed to several sublethal concentrations of cadmium (10, 40, 60 and 120 μM (mg/L)) for a period of 48, 96 and 192 h. The value of the LC50 after 96 h of cadmium exposure, dete...

Endosulfan is a widely used organochlorine pesticide with well-documented neurotoxic effects in both humans and laboratory animals (mammals and fish). Neurotoxicity has been implied also in amphibians after short-term exposure to endosulfan. Little is known about effects of chronic exposure of endosulfan in amphibians. Previously, we examined the s...

Endosulfan is an organochlorine pesticide used in agriculture for a wide range of crops.
