Abstract

Climate change and increasing nutrient concentrations are two major threats to lake ecosystems. Furthermore, warming is exacerbating the symptoms of eutrophication in freshwaters. Facing both environmental challenges simultaneously is more urgent than ever to preserve and recover water quality and protect the remaining biodiversity. Here, we used long-term observational data to investigate the phytoplankton response to the interaction between temperature and nutrient variations in a deep mesotrophic subalpine lake (L. Iseo, Italy). Despite the existing management programs, we observed a deterioration of the physicochemical status of the lake between 1993 and 2021 in the water column. The average rate of temperature increase was 0.02 °C y-1 across the studied period and accelerated after the last complete mixing events (2005 and 2006), particularly during the last decade (0.08 °C y-1). Water warming caused severe impacts on nutrient cycling, reflected by the overall increase in nutrient concentrations. The direct effect of warming was of great importance for phytoplankton, leading to an increase in total biovolume and a loss of diversity and promoting the dominance of Cyanobacteria. Nutrient variations, especially TN and the DSi:TP ratio, considerably structured the community composition. The modification of physicochemical parameters caused by the last complete mixing events led to a remarkable, long-term taxonomical and functional reorganization of the phytoplankton community. This study illustrates that phytoplankton in deep subalpine lakes will experience severe changes in the upcoming years, and that complete mixing events may constitute a threshold for community transformation. Our results stress the importance of using powerful interpretative models with multifaceted long-term datasets to disentangle the pathways by which temperature and nutrients could regulate the phytoplankton community. Our conclusions will help to integrate climate cha

9. Hierarchy and Polysynchrony in an adaptive network

Abstract

We describe a simple adaptive network of coupled chaotic maps. The network reaches a stationary state (frozen topology) for all values of the coupling parameter, although the dynamics of the maps at the nodes of the network can be non-trivial. The structure of the network shows interesting hierarchical properties and in certain parameter regions the dynamics is polysynchronous: nodes can be divided in differently synchronized classes but contrary to cluster synchronization, nodes in the same class need not be connected to each other. These complicated synchrony patterns have been conjectured to play roles in systems biology and circuits. The adaptive system we study describes ways whereby this behaviour can evolve from undifferentiated nodes., Comment: 13 pages, 17 figures

10. Families of piecewise linear maps with constant Lyapunov exponent

Nonlinear Sciences - Chaotic Dynamics, 37E05, 37B40
Abstract

We consider families of piecewise linear maps in which the moduli of the two slopes take different values. In some parameter regions, despite the variations in the dynamics, the Lyapunov exponent and the topological entropy remain constant. We provide numerical evidence of this fact and we prove it analytically for some special cases. The mechanism is very different from that of the logistic map and we conjecture that the Lyapunov plateaus reflect arithmetic relations between the slopes., Comment: 26 pages, 13 figures

11. Emergence of hierarchical networks and polysynchronous behaviour in simple adaptive systems

Author

Subjects
Nonlinear Sciences - Adaptation and Self-Organizing Systems
Abstract

We describe the dynamics of a simple adaptive network. The network architecture evolves to a number of disconnected components on which the dynamics is characterized by the possibility of differently synchronized nodes within the same network (polysynchronous states). These systems may have implications for the evolutionary emergence of polysynchrony and hierarchical networks in physical or biological systems modeled by adaptive networks., Comment: 4 pages, 4 figures

14. Dynamics of a map with power-law tail

Subjects
Nonlinear Sciences - Chaotic Dynamics
Abstract

We analyze a one-dimensional piecewise continuous discrete model proposed originally in studies on population ecology. The map is composed of a linear part and a power-law decreasing piece, and has three parameters. The system presents both regular and chaotic behavior. We study numerically and, in part, analytically different bifurcation structures. Particularly interesting is the description of the abrupt transition order-to-chaos mediated by an attractor made of an infinite number of limit cycles with only a finite number of different periods. It is shown that the power-law piece in the map is at the origin of this type of bifurcation. The system exhibits interior crises and crisis-induced intermittency., Comment: 28 pages, 17 figures

Abstract

Freshwaters constitute a fundamental and extremely limited resource for atoll islands' population. The interplay of climatic and human-driven processes, which affect both the quantity and the quality of freshwater resources, may exacerbate the problem of water security and availability. This work evaluated the effects of good spectrum of anthropic impacts on groundwater quality in a typical and representative native inhabited island (c.a. 850 people) of Maldives, analyzing and interpreting hydrological and hydrochemical data, collected during a specific field survey on 51 sampling points after a rainy season. The island groundwater is constituted by a thin asymmetric lens, periodically recharged by rain. The lifestyle of people and water exploitation seem to be sustainable, even if groundwater resources are already experiencing moderate contamination and, limited to some areas, heavy pollution. The sources of impacts have been identified in diffuse organic matter contamination due to a poor domestic wastewater treatment, farming (poultry) and gardening activities. To face these impacts, it is essential to build a sewer system paired with a possibility to recycle wastewater reducing water over-exploitation. The collaborative and educational initiatives organization, at different levels, can increase the capacity for planning a sustainable development. Our results provide useful information for sustainable management plans to preserve freshwater resources of the island, which conservation is especially important considering the context of the future lifestyle changes and climatic scenarios for the Maldives. These findings can be extended by analogy to others atoll islands.

Abstract

Recent studies have highlighted an increase of chloride in many lakes worldwide, with negative effects on chemical and physical properties of inland waters and freshwater biota. In this study, we assessed the long-term trend (1993–2017) of chloride in Lake Iseo, located in the midlatitudes, and analyzed its relationship with discharge data of the inflows and hydrological and hydroclimatic changes. Additionally, we performed a specific annual survey, collecting water samples at a biweekly frequency in tributaries, calculating chloride load, and comparing the result with the chloride increase observed in lacustrine water. The combined use of Geographic Information System (GIS) and multivariate analyses allowed identification of possible sources of chloride and their seasonal dynamic within the mixed-land-use watershed: impervious surface and deicing salt, population and sewage effluents, livestock, and rainwater. Their potential contribution to total mass balance was assessed, cross-checking the results between chloride source evaluation and load estimation. Chloride load from wastewater treatment plants played an important role, albeit we highlighted that the main source was the road deicing salt, with a primarily winter contribution. The increased anthropization in the watershed was likely the main cause of the chloride enhancement. This study demonstrates that the problem of salinization can also affect lakes located in the midlatitude areas and provides a reproducible method for the identification and quantification of the different sources. Our results will help to better understand the potential sources of salinity in rivers that may reveal processes controlling the salinization of freshwater systems, with implications for future management practices.
