Temporal changes in nutrients in a deep oligomictic lake: the role of external loads versus internal processes

Journal of Limnology, 2021
The impact of climate change on stratification and mixing patterns has important effects on nutrient availability and plankton dynamics in deep lakes.

The invasive appearance of Eudiaptomus gracilis (G.O. Sars 1863) in Lago Maggiore

Journal of Limnology, 2010
Large, deep, subalpine Lago Maggiore has been regarded as an example of stability and resilience: while changes in zooplankton taxa composition were mainly recorded with introduction of allochthonous fish in the 1950s, eutrophication and ...

Model simulations of the ecological dynamics induced by climate and nutrient load changes for deep subalpine Lake Maggiore (Italy/Switzerland)

Journal of Limnology, 2020
Climate warming affects lake ecosystems both through its direct effect on the phenology of species and through the alteration of the physical and chemical environments, which in turn affect community composition. In deep lakes, stratification enhancement

Population Space–Time Patterns Analysis and Anthropic Pressure Assessment of the Insubric Lakes Using User-Generated Geodata

ISPRS International Journal of Geo-Information, 2022
Human activities are one of the main causes of lake-water pollution and eutrophication. The study of human pressure around lakes is of importance to understand its effects on the lakes natural resources.

Fisheries impacts on lake ecosystem structure in the context of a changing climate and trophic state

Journal of Limnology, 2017
Through cascading effects within lake food webs, commercial and recreational fisheries may indirectly affect the abundances of organisms at lower trophic levels, such as phytoplankton, even if they are not directly consumed.

Mechanisms underlying recovery of zooplankton in Lake Orta after liming

Journal of Limnology, 2016
The goal of this study was to improve the understanding of the large-scale mechanisms underlying the recovery of the zooplankton of Lake Orta from historical contamination, following reduced input of ammonia and metals and the subsequent 1989/90 liming ...

Nitrogen budget of Lago Maggiore: the relative importance of atmospheric deposition and catchment sources

Journal of Limnology, 2001
Hydrological and chemical data of 1996 and 1997 are used to evaluate the relative contributions of atmospheric deposition and urban/industrial wastewaters to the nitrogen budget of Lago Maggiore.

Why bacteria are smaller in the epilimnion than in the hypolimnion? A hypothesis comparing temperate and tropical lakes

Journal of Limnology, 2012
Bacterial size and morphology are controlled by several factors including predation, viral lysis, UV radiation, and inorganic nutrients. We observed that bacterial biovolume from the hypolimnion of two oligotrophic lakes is larger than that of bacteria ...

Hydraulic paths and estimation of the real residence time of the water in Lago Maggiore (N. Italy): application of massless markers transported in 3D motion fields

Journal of Limnology, 2012
This study, conducted using the TRIM_LM model, is a continuation of work on the movement of the water mass at different depths in Lago Maggiore, and thus on the estimation of the real residence time of the water in the lake.
