Seawater carbonate chemistry and community structure and function of phytoplankton community

, 2022
The rise of atmospheric pCO2 has created a number of problems for marine ecosystem. In this study, we initially quantified the effects of elevated pCO2 on the group-specific mortality of phytoplankton in a natural community based on the results of ...

Learning Seasonal Phytoplankton Communities with Topic Models

CoRR, 2017
In this work we develop and demonstrate a probabilistic generative model for phytoplankton communities. The proposed model takes counts of a set of phytoplankton taxa in a timeseries as its training data, and models communities by learning sparse co-occurrence structure between the taxa.

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 ...

[Phytoplankton community in a recreational fishing lake, Brazil].

Revista de saude publica, 2004
OBJETIVO: A avaliação da qualidade da água e da comunidade fitoplanctônica em ambientes destinados à recreação permite estabelecer formas de manejo desses sistemas, evitando possíveis problemas à saúde humana. Assim, realizou-se estudo com objetivo de analisar a variação sazonal do fitoplâncton de um sistema lacustre natural, e sua relação com a ...

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.

Using optimized dimensionality reduction and machine learning to explain driving processes of phytoplankton community assembly in large mountain rivers

Ecological Indicators
Large mountain rivers create unique aquatic habitats and become one of biodiversity hot spots within ecosystems. Since phytoplankton constitutes a crucial component of primary productivity in aquatic ecosystems, understanding its community assembly ...
