Seagrasses under stress: Independent negative effects of elevated temperature and light reduction at multiple levels of organization

Limnology and Oceanography, EarlyView.
Abstract Seagrasses are important foundation species, which support coastal biodiversity and provide socioeconomic benefits. However, seagrasses are threatened by anthropogenic changes, including the elevated temperature associated with marine heatwaves (MHWs) and light limitation from eutrophication or increased sedimentation.

Gross oxygen production and microbial community respiration in the oligotrophic ocean

Limnology and Oceanography, EarlyView.
Abstract Uncertainties in the temporal and spatial patterns of marine primary production and respiration limit our understanding of the ocean carbon (C) cycle and our ability to predict its response to environmental changes. Here we present a comprehensive time‐series analysis of plankton metabolism at the Hawaii Ocean Time‐series program site, Station

Dynamics of surface accretion and surface elevation differ between river and tide dominated settings in tropical mangroves

Limnology and Oceanography, EarlyView.
Abstract The maintenance of soil surface elevation in mangroves supports the persistence of mangroves with sea level rise. The processes contributing to soil surface elevation have rarely been assessed in the humid tropics, despite most mangroves occurring in river deltas and tidal estuaries within this climate zone. Using surface elevation table (SET)

Seasonality modulates coral trophic plasticity in an extreme, multi‐stressor environment

Limnology and Oceanography, EarlyView.
Abstract Corals with high trophic plasticity, i.e., the ability to change the relative contribution of heterotrophic and autotrophic nutrition to their mixotrophic diet, can have increased tolerance to individual stressors, but it is poorly understood how trophic strategies shift in response to combined global (e.g., warming, acidification) and local ...

Stratification stability of tropical lakes and their sensitivity to climate

Limnology and Oceanography, EarlyView.
Abstract Tropical lakes experience less thermal convection than temperate lakes and can be stably stratified by temperature gradients alone. Deep tropical lakes are often presumed meromictic, but conditions for sustained meromixis are poorly constrained. Here, we investigate the stratification stability of a deep (200 m) tropical Lake Towuti (Indonesia)

Increasing acidification does not affect sexual reproduction of a solitary zooxanthellate coral transplanted at a carbon dioxide vent

Limnology and Oceanography, EarlyView.
Abstract The absorption of atmospheric carbon dioxide is causing significant changes to the carbonate chemistry of the ocean, in a phenomenon called ocean acidification. The latter makes it potentially more difficult for marine calcifiers like corals, to build their calcium carbonate structures, thus affecting their ability to survive and reproduce ...

Seasonal and spatial transitions in phytoplankton assemblages spanning estuarine to open ocean waters of the tropical Pacific

Limnology and Oceanography, EarlyView.
Abstract Islands in the tropical Pacific supply elevated nutrients to nearshore waters that enhance phytoplankton biomass and create hotspots of productivity in otherwise nutrient‐poor oceans. Despite the importance of these hotspots in supporting nearshore food webs, the spatial and temporal variability of phytoplankton enhancement and changes in the ...

Continental‐scale seston stoichiometry reveals fundamental constraints on the elemental composition of particles transported by streams

Limnology and Oceanography, EarlyView.
Abstract Suspended particulate matter, or seston, represents an understudied flux of carbon (C), nitrogen (N), and phosphorus (P) in river networks. Here, we summarize riverine seston C : N : P stoichiometry data from 27 streams and rivers sampled regularly from 2014 to 2022 across the United States by the National Ecological Observatory Network (NEON).

Heterotrophy of particulate organic matter subsidies contributes to divergent bleaching responses in tropical Scleractinian corals

Limnology and Oceanography, EarlyView.
Abstract Heterotrophic feeding on plankton and particulate organic matter (POM) by tropical Scleractinian corals is known to aid in the resistance and recovery from thermally induced bleaching. However, the relative importance of heterotrophy in promoting bleaching resistance and recovery is likely to vary based on ecological context and the severity ...
