Ecological associations distribution modelling of marine plankton at a global scale

Marine plankton communities form intricate networks of interacting organisms at the base food chain, and play a central role in regulating ocean biogeochemical cycles climate. However, predicting community shifts response to climate change remains challenging. While species distribution models are valuable tools for changes biogeography under scenarios, they generally overlook key biotic interactions, which can significantly shape ecological processes ecosystem responses. Here, we introduce novel statistical framework, association modelling (ADM), designed model predict associations space time. Applied on Tara Oceans genome-resolved metagenomics dataset, present-day ADM-inferred marine revealed four major biogeographic biomes organized along latitudinal gradient. We predicted evolution these biome-specific scenario, highlighting differential responses environmental change. Finally, explored functional potential impacted communities, focusing carbon fixation, outlining its geographical implications function.

Spatial analysis of plankton distribution in Northern Waters of Aceh: An indicator of marine environmental quality

BIO Web of Conferences, Journal Year: 2025, Volume and Issue: 156, P. 02005 - 02005

Published: Jan. 1, 2025

Plankton, especially phytoplankton, serves as the essential building block of marine food chain. As a result, presence plankton in body water is frequently utilized measure quality and primary productivity. This study aims to determine plankton's spatial patterns Northern Aceh's waters bioindicator quality. The distribution was analyzed through sampling at several points sea Waters Aceh (NWA). Plankton analysis included abundance, diversity, community composition. Concurrently, an environmental parameters, including temperature, salinity, pH, dissolved oxygen, conducted. Information on abundance parameters then linked identify their relationships. Furthermore, understand plankton, correlated with spectral bands from satellite imagery. results indicate variation NWA due physicochemical seawater. Analysis reveals that Cyanobacteria, Bacillariophyta (diatoms), Chlorophyta, Arthropoda, Rotifera are present NWA, being most dominant. dominance (diatoms) over combined absence Pseudo-nitzschia spp., highlights good ecological health fertility NWA.

Co‐occurrence and successional patterns among diatoms, dinoflagellates, and potential parasites in a coastal upwelling experiment

Abstract Diatom‐dominated blooms in coastal upwelling systems contribute disproportionately to global primary production. The fate of carbon captured during a diatom bloom is often influenced by species‐specific ecological differences. However, successional patterns that take place are oversimplified, and the diversity adaptations different stages remains poorly characterized. To improve our understanding specificity certain conditions within bloom, we employed microscopy, 18S rRNA amplicons, biogeochemical analysis simulated mesocosm experiment. We successfully found diatoms bloomed early late phases bloom. Surprisingly, relative abundance congeneric with Thalassiosira , Chaetoceros Pseudonitzschia displayed opposing were consistent among experimental mesocosms. stage was especially interesting because some continued mixotrophic dinoflagellate genera Akashiwo Heterocapsa Prorocentrum . Additionally, Syndiniales putative parasites correlated several diatoms, initial phase novel observations rapid changes mesocosms reflect ability occupy fall outside traditional expectations. parasite co‐occurrence blooming may be important trends populations, this parasitic interaction deserves further study systems. This indicates there underlying traits biotic interactions should considered when estimating their contribution productivity cycling
