Limnology and Oceanography, EarlyView.Abstract Despite ongoing efforts to reduce nutrient inputs, eutrophication continues to disrupt biogeochemical cycles and destabilize freshwater food webs. In this study, we examine the stoichiometric responses of the freshwater plant Myriophyllum spicatum under varied environmental conditions across lakes of differing trophic status.

Disentangling the effects of climate change in a mountain lake through community structure analysis
Limnology and Oceanography, EarlyView.Abstract Pressures of climate change may trigger regime shifts in ecosystems. Identifying signs of these pressures before the critical transition remains challenging, and it could be useful to anticipate the regime shift. In this research, while exploiting the case of a lacustrine ecosystem, which passed from an unvegetated, phytoplankton‐dominated ...

The effects of alewife (Alosa pseudoharengus) on zooplankton community structure in Depot Pond NH and a comparison of seven New Hampshire lakes [PDF]
, 1999 Physical, chemical and biological features of seven New Hampshire lakes were examined in September and October of 1997. Zooplankton communities exhibited evidence of “top-down” control in Milton Three Ponds (Depot, Norteast, and Townhouse Ponds), showing

Limnology and Oceanography, EarlyView.Abstract Regulation and water extraction change flow regimes in lowland rivers, affecting ecosystem functions and wetting patterns of riverbanks. River connectivity to lateral environments is crucial for organic matter cycling and the life cycles of diapausing microinvertebrates. While extreme hydraulic periods (floods and cease‐flow) are well‐studied,

From Headwaters to the Sea: The Journey of Creating an Immersive Museum Exhibit
Limnology and Oceanography Bulletin, EarlyView.Abstract We describe the multi‐year journey of a group of researchers co‐creating a museum exhibit with the Biosphère an environmental museum of the City of Montréal. The collaboration resulted in an immersive experience where visitors can dive into an aquatic continuum and learn about function, ecology, chemistry, and the roles of the various aquatic ...

Biogeochemical Markers to Identify Spatiotemporal Gradients of Phytoplankton across Estuaries
CoastsThe spatiotemporal distribution of phytoplankton in estuaries is indicative of processes and transport across the land–ocean aquatic continuum (LOAC). Estuaries, as biogeochemically and physically active systems, process large amounts of nutrients and ...

Discrete dynamics of phytoplankton-zooplankton systems with Holling type functional responses [PDF]
arXivIn this paper, we study discrete dynamics of phytoplankton-zooplankton system with Holling type II and Holling type III predator functional responses. The stability of positive fixed points are investigated. By finding invariant sets, the convergence of the trajectory was shown under certain conditions on the parameters.
