Abstract One of the most important physical characteristics driving lifecycle events in lakes is stratification. Already subtle variations timing stratification onset and break-up (phenology) are known to have major ecological effects, mainly by determining availability light, nutrients, carbon oxygen organisms. Despite its importance, historic future global changes phenology unknown. Here, we used a lake-climate model ensemble long-term observational data, investigate lake across Northern...
An experiment in >1000 river and riparian sites found spatial patterns controls of carbon processing at the global scale.
Abstract. Empirical evidence demonstrates that lakes and reservoirs are warming across the globe. Consequently, there is an increased need to project future changes in lake thermal structure resulting biogeochemistry order plan for likely impacts. Previous studies of impacts climate change on have often relied a single model forced with limited scenario-driven projections relatively small number lakes. As result, our understanding effects fragmentary, based scattered using different data...
Abstract Recent studies have highlighted the impact of winter North Atlantic Oscillation (NAO) on water temperature, ice conditions, and spring plankton phenology in specific lakes regions Europe. Here, we use meta‐analysis techniques to test whether 18 northern, western, central Europe respond coherently climate forcing, assess persistence signal physical, chemical, biological variables during year. A approach was chosen because wished emphasize overall coherence pattern rather than...
Summary 1. Weather‐related episodic events are typically unpredictable, and their duration is often short. Abiotic biological responses missed in routine monitoring. These are, however, now of particular relevance given projected changes extreme weather conditions. 2. We present data from high‐frequency monitoring stations lakes Europe, North America Asia that illustrate two classes abiotic effects events: (i) generally short‐lived storms on lake thermal structure (ii) the more prolonged...
The assessment report of the 4th International Panel on Climate Change confirms that global warming is strongly affecting biological systems and 20–30% species risk extinction from projected future increases in temperature. It essential any measures taken to conserve individual their constituent populations against climate-mediated declines are appropriate. release captive bred animals augment wild a widespread management strategy for many but has proven controversial. Using regression model...
We report the first application of CRISPR-Cas technology to single species detection from environmental DNA (eDNA). Organisms shed and excrete into their environment such as in skin cells faeces, referred Utilising eDNA allows noninvasive monitoring with increased specificity sensitivity. Current methods primarily employ PCR-based techniques detect a given samples, posing logistical challenge for on-site potential adaptation biosensor devices. have developed an alternative method; coupling...
Lakes are significant emitters of methane to the atmosphere, and thus important components global budget. Methane is typically produced in lake sediments, with rate production being strongly temperature dependent. Local regional studies highlight risk increasing under future climate change, but a estimate not currently available. Here, we project changes bottom temperatures sediment rates from 1901 2099. By end 21st century, projected increase globally, by an average 0.86-2.60°C...
Global projections of lake evaporation are typically based on simulations using single mechanistic models. However, because its complex interactions with various physical properties, environmental and anthropogenic drivers, is highly variable sensitive to the choice model used. In this study, we present a multi-model analysis investigate differences across global during warm-season three different models driven by outputs from four general circulation (GCM) (i.e. 12 combinations in total)...
A grassroots, global network to examine lake function using sensor data?Why not?That was the perspective of Drs.
A Global Lake Ecological Observatory Network (GLEON; www.gleon.org) has formed to provide a coordinated response the need for scientific understanding of lake processes, utilising technological advances available from autonomous sensors. The organisation embraces grassroots approach engage researchers varying disciplines, sites spanning geographic and ecological gradients, novel sensor cyberinfrastructure synthesise high-frequency data at scales ranging local global. platform rigorously...
Climate projections indicate that the frequency and severity of extreme precipitation events will increase over next century. Although a large number lakes across globe are systematically monitored, it is rare to have wide range ecological indices measured at high enough sufficient time scale allow characterisation response lake ecosystem such events. We present data from Lough Feeagh, relatively oligotrophic in Ireland, which was epicentre once 250-year event July 2009 when 50 mm rain fell...
Abstract. The epilimnion is the surface layer of a lake typically characterised as well mixed and decoupled from metalimnion due to steep change in density. concept (and, more widely, three-layered structure stratified lake) fundamental limnology, calculating depth essential understanding many physical ecological processes. Despite ubiquity term, however, there no objective or generic approach for defining epilimnion, diverse number approaches prevail literature. Given increasing...
We determined relative nitrate‐nitrogen (NO 3 ‐N) loss rates in 100 north‐mid‐European lakes from late spring to summer by using the exponential function N 2 = 1 e −k(t −t ), where and are NO ‐N concentrations at beginning (t ) end of time interval, respectively, k is specific rate. found that decreased with increasing lake depth. Adjusting depth (k adj we observed was positively related concentrations, but this relationship became insignificant mean depths exceeding 12.5 m. A between...
Invasive Alien Species (IAS) are a growing threat to Europe's biodiversity. The implementation of European Union Regulation on IAS can benefit from the involvement public in recording and management through Citizen Science (CS) initiatives. Aiming tackle issues related with use CS projects topics, dedicated workshop titled "Citizen Open Data: model for Europe" was organized by Joint Research Centre (JRC) Cooperation Technology (COST Association). Fifty key stakeholders all Europe, including...
In 2018, Europe experienced the warmest May–October (Northern Hemisphere warm season) since air temperature records began. this study, we ran model simulations for 46 557 lakes across to investigate influence of heatwave on surface water temperature. We validated with satellite-derived lake temperatures 115 from 1995 2018. Using model, demonstrated that, during mean and maximum were 1.5 2.4 °C warmer than base-period average (1981–2010). A experiment average, increase in was dominant driver...

Reduction of freshwater habitat quality due to land use change can have major impacts on diadromous fish. Partitioning this impact from other potential drivers, such as changing marine conditions and climate, is hampered by a lack long-term data sets. Here, four decades were used assess the Salmo salar anadromous trutta in Burrishoole catchment, Ireland, one few index sites for fish North Atlantic. Land was found no significant survival either salmon or trout. However, climate impacted...
