Long-term monitoring of data ambient mercury (Hg) on a global scale to assess its emission, transport, atmospheric chemistry, and deposition processes is vital understanding the impact Hg pollution environment. The Global Mercury Observation System (GMOS) project was funded by European Commission (http://www.gmos.eu) started in November 2010 with overall goal develop coordinated observing system monitor scale, including large network ground-based stations, ad hoc periodic oceanographic...
Abstract. The atmospheric deposition of mercury (Hg) occurs via several mechanisms, including dry and wet scavenging by precipitation events. In an effort to understand the cycling seasonal depositional characteristics Hg, samples were collected for approximately 5 years at 17 selected GMOS monitoring sites located in Northern Southern hemispheres framework Global Mercury Observation System (GMOS) project. Total (THg) exhibited annual patterns Hg samples. Interannual differences total are...
Abstract Terrestrial inputs of dissolved organic matter ( DOM ) make a significant contribution to the carbon pool headwaters and reactivity this depends on its source diagenetic state, being influenced by photochemical biological processes. The main goal study was characterise composition soil leaf litter from native forest Nothofagus pumilio (Nothofagaceae), natural stream water, evaluating effect degradation Photo‐ biodegradation laboratory experiments were conducted using leached litter,...
Disturbances fundamentally alter ecosystem functions, yet predicting their impacts remains a key scientific challenge. While the study of disturbances is ubiquitous across many ecological disciplines, there no agreed-upon, cross-disciplinary foundation for discussing or quantifying complexity disturbances, and consistent terminology methodologies exist. This inconsistency presents an increasingly urgent challenge due to accelerating global change threat interacting that can destabilize...
Abstract This study analyses the effects of interplay between climate seasonality and hydrogeomorphic (HGM) lake features on dissolved organic matter (DOM) properties in two neighbouring shallow lakes Andean Patagonia with different connectivities. The survey was conducted over three years at end wet dry seasons, assessing seasonal interannual variation carbon (DOC) concentration, whole‐lake DOC mass, DOM quality, through chromophoric fluorescent (CDOM FDOM, respectively) properties. During...
Abstract Estimating organisms' responses to environmental variables and taxon associations across broad spatial scales is vital for predicting their climate change. Macroinvertebrates play a major role in wetland processes, but studies simultaneously exploring both community structure trait gradients are still lacking. We compiled global dataset (six continents) from 756 depressional wetlands, including the occurrence of 96 macroinvertebrate families, phylogenetic tree, 19 biological traits....
Abstract Background Crohn’s disease(CD) is a chronic inflammatory bowel disease, characterized by progressive course that leads to structural damage(SBD).There no clear definition of SBD.However, the presence detectable complications through imaging techniques, such as strictures, fistulas or abscesses widely accepted describe SBD.Therefore, reversing damage an emerging medical goal in time biological treatments Methods The main objective this study was assess ability reverse monitored...
Inland waters are hotspots for biogeochemical activity, but the environmental and biological factors that govern transformation of organic matter (OM) flowing through them still poorly constrained. Here we evaluate data from a crowdsourced sampling campaign led by Worldwide Hydrobiogeochemistry Observation Network Dynamic River Systems (WHONDRS) consortium to investigate broad continental-scale trends in OM composition compared localized events influence transformations. Samples two...

Photoprotective compounds (PPCs), such as carotenoids and mycosporine-like amino acids (MAAs), confer photoprotection to aquatic organisms against harmful ultraviolet-B (UVB) radiation. The natural variability of these in zooplankton has been related temperature, radiation diet, but the ultimate mechanisms regulating observed patterns field are still unclear. In this study, we analysed MAAs a population calanoid copepod Boeckella antiqua shallow pond located Northern Patagonia (Argentina)....
Abstract North‐western Patagonia contains a variety of glacially formed mountain lakes located at different positions from the treeline in Andean Patagonian forest region. Water chemistry six North an altitudinal gradient, above, and below (~41°S) were analysed this study. The relative importance allochtonous to autochthonous carbon inputs along marked catchment vegetation gradient encompassing altoandino Nothofagus forests was addressed. dissolved organic ( DOC ) concentration varied among...
Abstract We addressed the influence of bioclimatic variables (precipitation, temperature and vegetation) on physicochemical properties, carbon (C) nutrients dynamics in shallow temperate lakes northern Patagonian Andes. Four (mean depth < 15 m) located along Andean gradient, characterised by a west‐to‐east decrease precipitation, increase changes vegetation type, were studied during wet dry periods. Physicochemical variables, total nitrogen phosphorus (TN TP) particulate dissolved organic...
