Effects of preservatives and poisons on the elemental and isotopic composition of freshwater particulate organic matter

Limnology and Oceanography: Methods, EarlyView.
Abstract Sediment traps, often used in tandem with preservatives or poisons, are widely used for the collection of particulate organic matter (POM), providing insight into the source to sink mechanisms that shape major biogeochemical cycles and sedimentary carbon sequestration.

Microbially driven organic carbon cycling at the land−sea interface: Advances and an integrated study framework

mLife, EarlyView.
Abstract The land−sea interface is a vital component of global biogeochemical cycles, where microorganisms drive the cycling of carbon, nitrogen, and sulfur. This review synthesizes the research progress from representative land−sea interfaces to elucidate how the microbial community structure and metabolic function influence the mobilization ...

Benthic megafauna and the functioning of macroalgal forests and urchin barrens

Oikos, EarlyView.
Two temperate rocky reef food‐web models, representing the trophic diversity of the Mediterranean rocky reef communities, were built for the two stable states: macroalgal forests and barren grounds, which are characterized by opposite amounts of erect macroalgal biomass.

Multitrophic alpha and beta diversity of lake plankton across Canada

Oikos, EarlyView.
Anthropogenic environmental changes impact freshwater biodiversity globally. While biodiversity assessments in freshwater environments have traditionally focused on individual groups of organisms or trophic levels, considering patterns of ‘multitrophic biodiversity' across the food web provides a more comprehensive view of anthropogenic impacts and ...

Drivers of metabolic density‐dependence: how resource availability and conspecific cues affect phytoplankton metabolism

Oikos, EarlyView.
Metabolism is density‐dependent from unicellular to multicellular organisms. Understanding what drives metabolic suppression is important to explain population growth given the link between metabolism and biomass production. In the simplest scenario, metabolic suppression is caused by a reduction in resource availability with increasing population ...

Calibrating p‐values in ecology: a practical framework for integrating prior plausibility into statistical inference

Oikos, EarlyView.
Misinterpretation of p‐values, coupled with insufficient consideration of the prior plausibility of ecological hypotheses, leads to overconfident and often unreliable inference in ecological research. To address this issue, we present a methodological framework for p‐value calibration that reinterprets conventional p‐values through minimum Bayes ...

Role of hydraulic residence time in shaping phytoplankton community assembly in the upper yellow river cascade reservoirs

Frontiers in Environmental Science
Introduction: Cascade hydropower development significantly alters the structure and function of river ecosystems. Phytoplankton, as primary producers, are highly sensitive to environmental changes, and their diversity and community structure reflect the ...

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

High-resolution observations on fine-scale spatial and temporal heterogeneity of phytoplankton communities using FlowCAM

, 2019
To understand the fine-scale spatio-temporal phytoplankton dynamics with reference to the environmental properties of the water column, high-frequency samplings every 4 h, at 0.5-2 m depth intervals using a submersible pump was conducted in Tateyama Bay,

Examining the Role of Economic Complexity and Climate Readiness in the Climate‐Fishing Nexus

Sustainable Development, EarlyView.
ABSTRACT This paper investigates the climate‐fisheries association in Gulf Cooperation Council (GCC) nations from 1999 to 2022. A key objective is to explore the role of both the economic complexity index (ECI) and the climate readiness factor (READ) in the climate‐fishing nexus.
