1. Data for maximum colonization depth ( Z c ) of five groups submerged macrophytes and light attenuation were collected forty‐five Danish lakes 108 non‐Danish lakes. The macrophyte bryophytes, charophytes, caulescent angiosperms, rosette‐type angiosperms Isoetes spp. 2. data showed systematic differences among the in relationship to water transparency. In with low transparency (Secchi disc s less than 7 m) charophytes penetrated deepest followed by bryophytes more transparent grew deepest,...
Abstract Environmental DNA (eDNA) is increasingly used for monitoring marine organisms; however, offshore sampling and time lag from to results remain problematic. In order overcome these challenges a robotic sampler, 2nd generation Sample Processor (ESP), was tested autonomous analysis of eDNA four commercial fish species in 4.5 million liter mesocosm. The ESP enabled situ analysis, consisting water collection, filtration, extraction qPCR which allowed real-time remote reporting archival...
1200 measurements of eelgrass ( Zostera marina ) biomass, shoot density and cover along 19 depth gradients in Øresund, located between Denmark Sweden, were analysed to characterise growth relation depth. The large data set allowed analyses boundaries distribution as well average trends. Natural variability is shallow water where populations are disturbed by wave action other physical parameters. Models based on values, therefore, did not adequately describe regulation resources, only...
Abstract There are many spatial issues associated with aquaculture which must be understood in order to support sustainable development and mitigate other potential issues. Geographic Information Systems (GIS) used for investigation, analysis modelling of there have been a considerable number studies since the late 1980s. However, despite range applications, GIS is still often underutilized stakeholders requested more GIS‐based tools management regulation sector. Consequently, need establish...
Plant communities utilize available irradiance with different efficiency depending not only on their photosynthetic characteristics but also the canopy structure and density. The importance of are well studied in terrestrial plant poorly aquatic communities. objective this study was to evaluate macroalgal community photosynthesis artificial constructed one four species morphologies along a range leaf (i.e.=thallus) area densities. In laboratory set‐up we measured net dark respiration...
Abstract The maximum final pHs reached during extended photosynthesis were 8.83 for the red algae Delesseria sanguinea and 10.19 brown Fucus vesiculosus, as long concentrations of exceeded 1 mmol l−1, suggesting existence an upper pH limit macroalgal photosynthesis. In experiments initiated with low inorganic carbon, decreased reduced initial pH, indicating that carbon became limiting. Effects high O2 could be ruled out a contributing factor in drift at or above 7.5. growth rates both...
Long-term studies of the composition marine macroalgal communities are rare because lack quantitative investigations in past. In Denmark, a single study was performed 1941–1943 nontidal estuary Isefjord–Roskilde Fjord, at several sites variable salinity (10–22 ‰) and nutrient availability. This used as reference for evaluating changes richness relative abundance species from different taxonomic groups functional forms experiencing increasing concentrations nitrate light attenuation during 50...
The decline of species diversity benthic macroalgae in estuaries has been explained mainly by the physiological restrictions imposed reduced salinity, although a complex factors is likely to influence distribution. A comprehensive distributional index for 422 marine 22 districts Kattegat-Baltic brackish region provided an opportunity analyze detail regulating number and composition. Kattegat source area predominantly algal flora Baltic Sea. narrow Danish straits are main barriers exchange...
We analyzed species number of macroalgae in relation to environmental variables at two spatial levels comprising 202 individual sites and 26 entire estuaries Denmark. The increased with salinity declined nutrient concentrations both the estuaries. Availability hard substratum was associated higher richness sites. macroalgal mean depth longer coastline, suggesting that vertical horizontal extension colonization area are important for maximum representation species. Mean explained as a single...
Abstract Monitoring, understanding, and communicating the impact of offshore oil gas exploration production (E&P) activities on marine mammal (MM) biodiversity can be challenging. Here, we share methods, results, experiences accumulated during seven years monitoring MM underwater sound in a mature E&P activity area North-East Atlantic. We collected data distribution behaviour MM, their prey changes associated with impulsive (e.g., seismic) continuous platform) generated by...
Traditional marine monitoring can be a resource-intensive process that often covers network of sampling stations where data are collected manually by divers, or discretely using in situ water samples at different depths fixed positions followed laboratory analysis. As such, environmental status is reported after delay months years. However, things set to change for the better. Recent advances technologies, such as remote sensing, machine learning techniques, modeling non-experts, acoustic...
An 18 km long immersed tunnel is going to be built between Denmark and Germany. The construction works include dredging for the trench reclamation of areas in coastal zone. paper discusses baseline conditions potential impacts on aquatic environment works.
