Future phytoplankton diversity in a changing climate
Nature Communications, 2021 Phytoplankton form the base of the marine ecosystem but current ocean models used for climate change projections are too simple to assess potential changes in plankton community structure.

Oikos, EarlyView.The origins of ecosystem stability have long intrigued ecologists. Recent theoretical advancements highlight three primary mechanisms driving stability: dominance, asynchrony and averaging. While plant community stability has been extensively studied, our understanding of marine community stability remains limited. Plankton, as key components of marine

Temperature and species richness effects in phytoplankton communities [PDF]
Oecologia, 2012 Phytoplankton play an important role as primary producers and thus can affect higher trophic levels. Phytoplankton growth and diversity may, besides other factors, be controlled by seasonal temperature changes and increasing water temperatures. In this study, we investigated the combined effects of temperature and diversity on phytoplankton growth.

Frontiers in Marine ScienceWarming is a key factor influencing the function of the structure and function of phytoplankton communities. However, the impacts of temperature on phytoplankton resource use efficiency (RUE) in mountain rivers remain poorly understood.

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 ...

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.

Identification of environmental factors affecting the abundance and distribution of phytoplanktons in Shamil Dam Lake [PDF]
بومشناسی آبزیان, 2019 Microscopic suspended algae, or phytoplankton, are the prime source of organic matter supporting food webs in freshwater ecosystems. Studying the distribution of their population and understanding the interactions between environmental factors and the ...

Warming modifies trophic impacts of invading shrimp with impact varying among primary producers
Oikos, EarlyView.Environmental change drivers, such as climate change and species invasions, can disrupt biological networks and weaken ecosystem stability. Acting together, these drivers may interact and alter the effects on the ecosystem. However, few studies have examined the interactive effects of climate change and species invasions, particularly in aquatic ...
