Abstract Fish exhibit complex social behaviours that can influence their stress levels and well-being. However, little is known about the link between interactions in wild fish, especially running water environments. While many studies have explored axis most focused on specific contexts, leaving gaps understanding responses to changes. Our study investigated collective behaviour Italian riffle dace ( Telestes muticellus ) a controlled experimental setup simulating natural river system....

Living in extreme environments, marine organisms face constant exposure to a range of stressors, such as high radiation levels, fluctuations temperature, and oxidative stress. Understanding extremophile fishes is crucial because it gives us valuable insights into the biochemical, physiological, developmental processes that govern life, by observing how they operate under natural stressors. Among most fascinating adaptations existence specialised enzymes compounds function potent...

Metal bioaccumulation and metallothionein (MT) expression were investigated in the gills liver of red-blooded Antarctic teleost Trematomus hansoni to evaluate possibility for this species face, with adequate physiological responses, an increase copper cadmium concentrations its tissues. Specimens fish collected from Terra Nova Bay (Ross Sea) used a metal exposure experiment controlled laboratory conditions. The two treatments led significant accumulation both metals increased gene...

In recent decades, the interest in PFAS has grown exponentially around world, due to toxic effects induced by these chemical compounds humans, as well other animals and plants. However, current knowledge related antistress responses that organisms can express when exposed substances is still insufficient and, therefore, requires further investigation. The present study focuses on antioxidant Squalius cephalus Padogobius bonelli, significant levels of an area Veneto Region subjected a...

Antarctica is the continent with lowest local human impact; however, it susceptible to pollution from external sources. Emerging pollutants such as perfluoroalkyl substances pose an increasing threat this environment and therefore require more in-depth investigations understand their environmental fate biological impacts. The present study focuses on expression analysis at transcriptional level of genes coding for four antioxidant enzymes (sod1, sod2, gpx1, gpx4) in liver kidney Antarctic...

Given the pervasive detection of perfluoroalkyl substances (PFAS) in several environmental matrices and their known toxicological effects, it is imperative to investigate impact on physiological responses freshwater organisms. This research crucial for developing effective strategies protect aquatic ecosystems by directly addressing how PFAS influences species' health survival. In this study, we conducted a biomonitoring analysis evaluate effects naturally occurring PFAS, specifically...

Light pollution poses significant ecological challenges for nocturnal animals reliant on natural light migration, orientation, and circadian rhythms. The physiological effects of abrupt exposure to artificial at night (ALAN) migratory fish, such as the experienced passing near illuminated infrastructures, remain poorly understood. This study investigates responses brown trout (Salmo trutta) smolts low-intensity (0.02 lx) short-term (30 seconds) ALAN, simulating migration conditions bridges....

Stress granules (SGs) are cytoplasmic foci lacking membranes, comprising non-translating messenger ribonucleoproteins, translational initiation factors, and additional proteins. Their formation is crucial for rapidly modulating gene expression in response to adverse environmental conditions, such as pollution infections. Limited research has focused on investigating the molecular components of SGs fish, with minimal exploration Antarctic fish. This study characterises first time transcript...

Metallothioneins (MTs) are low-molecular weight sulfur-rich proteins, widely distributed in nature. They play a homeostatic role the control and detoxification of metal ions. Previous studies indicated that MTs also have capacity to scavenge reactive oxygen species. This study aimed investigate evolution protein notothenioid fish, evolved under selective pressure relatively high partial pressures, characteristics cold Antarctic seawaters, concentrations ions, Cd Cu particular. The cDNA...

This work aimed to evaluate the effects of zinc (Zn) relating cadmium (Cd)-induced toxicity and role played by MTF-1. transcription factor regulates expression genes encoding metallothioneins (MTs), some Zn transporters heavy chain γ-glutamylcysteine synthetase. For this reason, two cell lines mouse fibroblasts were used: a wild-type strain knockout study effects.

Antarctica is the continent with lowest local human impact, yet it still vulnerable to contaminants coming from external sources. Emerging pollutants, like PFAS, pose an increasing threat this environment and therefore require more in-depth investigations understand their environmental fate biological impacts. The present study, part of AntaGPS project, focuses on expression analysis at transcriptional level genes coding for 4 antioxidant enzymes (sod1, sod2, gpx1, gpx4) in different organs...

The present work consists in an experimental research based on the teaching and learning of Biology primary school.The aims this are two.The first is to support current scientific evidence that underlines effectiveness laboratory didactics.The second prove method makes it possible deal with several topics which not currently mentioned Italian Guidelines.Nowadays, demonstrates didactics has a stronger impact lifelong than traditional didactic approaches, frontal lessons only.The...

A topic that receives much attention, not only according to the main Italian (Italian Guidelines for Curriculum in Primary School - 2012 Edition) and European law documents (Recommendation of Parliament Council, 18 December 2006), is animals. This a vast subject can be addressed single school cycle. Hence emerges need consider aspects characterize One these concerns their morphology, different from species but which maintains common traits on it necessary focus attention. Furthermore,...
