Abstract Current levels of Ultraviolet Radiation (UVR) represent a significant threat to many fish species. The first studies on the effects UVR organisms were performed at beginning twentieth century, and topic has been progressing continuously until present. Here, we review reported harmful ultraviolet B (UVB) A (UVA) radiations in different lifecycle stages, including embryo, larvae, juveniles adults. most evident negative during early development stages are an increase mortality incidence developmental malformations, with skin gills affected tissues larvae. Growth reduction, loss body condition, behavioral, physiological metabolic changes juveniles/adults occur under short- or long-term UVB exposure. undergoes profound morphological functional changes, even after acute exposure UVR. Impairment molecular cellular processes was evidenced all by increasing DNA damage, apoptosis changing tissues’ antioxidant status. photo-protective mechanisms cope excessive also revised. Currently, stratospheric ozone dynamics climate change interact strongly, enhancing potential water. Due these environmental exposed new complex interactions between stressors, which potentially affects growth survival. Understanding ability adapt will be essential evaluate impact fisheries mitigate ecological problems.

Abstract. In recent years, airborne microplastics have been identified in a range of remote environments. However, data throughout the Southern Hemisphere, particular Antarctica, are largely absent to date. We collected snow samples from 19 sites across Ross Island region Antarctica. Suspected microplastic particles were isolated and their composition confirmed using micro-Fourier transform infrared spectroscopy (µFTIR). all Antarctic at an average concentration 29 L−1, with fibres most common morphotype polyethylene terephthalate (PET) polymer. To investigate sources, backward air mass trajectories run time sampling. These indicate potential long-range transportation up 6000 km, assuming residence 6.5 d. Local sources also as inputs into environment polymers consistent those used clothing equipment nearby research stations. This study adds growing body literature regarding ubiquitous pollutant establishes presence

The oceans take up over 1 million tons of anthropogenic CO2 per hour, increasing dissolved pCO2 and decreasing seawater pH in a process called ocean acidification. At the same time greenhouse warming surface results enhanced stratification shoaling upper mixed layers, exposing photosynthetic organisms dwelling here to increased visible UV radiation as well decreased nutrient supply. In addition, eutrophication reduce concentration O2 seawater, contributing spread hypoxic zones. All these global changes interact affect marine primary producers. Such interactions have been documented, but much smaller extent compared responses each single driver. combined effects could be synergistic, neutral or antagonistic depending on species physiological processes involved experimental setups. For most calcifying algae, impacts acidification, solar and/or elevated temperature clearly their calcification; for diatoms, light levels enhance growth at low, inhibit it high sunlight. nitrogen fixers (diazotrophs), acidification associated with may N2 fixation activity, other environmental variables such trace metal availability neutralize even reverse effects. Macroalgae, hand, either juveniles adults, appear benefit from rates tolerance lowered pH.

Overall, change biology studies used double stressors laboratory tests. This overview examines features warming, deoxygenation, focussing

Abstract This assessment by the Environmental Effects Assessment Panel (EEAP) of United Nations Environment Programme (UNEP) provides latest scientific update since our most recent comprehensive (Photochemical and Photobiological Sciences, 2019, 18, 595–828). The interactive effects between stratospheric ozone layer, solar ultraviolet (UV) radiation, climate change are presented within framework Montreal Protocol Sustainable Development Goals. We address how these global environmental changes affect atmosphere air quality; human health; terrestrial aquatic ecosystems; biogeochemical cycles; materials used in outdoor construction, energy technologies, fabrics. In many cases, there is a growing influence from seasonality extreme events due to change. Additionally, we assess transmission severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which responsible for COVID-19 pandemic, context linkages with UV radiation Protocol.
