Sustained Heatwaves Reshape the Phytoplankton-Zooplankton Community Structure in Freshwater Ecosystems: A Case Study of Shengjin Lake. [PDF]

Ecol Evol
The sustained heatwave has shaped the plankton community structure and led to high‐temperature domestication of some of the plankton. Plankton communities have the ability to resist heatwave stress. The sustained heatwave has altered the interrelationships between plankton.

New Approaches to Assess Food Web Stability in Aquatic Ecosystems: A Case Study on Baiyangdian Lake. [PDF]

Ecol Evol
A method for calculating the interaction strength of a phytoplankton‐based and a detritus food web. A geometric mean ratio of predator‐to‐prey biomass BCBPt$$ {\left(\frac{B_C}{B_P}\right)}_t $$ as an alternative indicator for food web stability. The changes in the stability of the BYD Lake from the 1950s to the 2010s indicate that two steady‐state ...

Recurrent Heatwaves Slow Down the Recovery of a Phytoplankton Community. [PDF]

Ecol Evol
Our study evaluates how repeated heatwaves affect the ecological resilience of freshwater communities. It shows that repeated heatwaves result in a critical slowing down of phytoplankton communities and underscore potential for reduced overall resilience due to repeated heatwave events.

Divergent Response of Host-Specific Driven Gut Microbial Stability in Freshwater Gastropods to Cyanobacterial Blooms. [PDF]

Ecol Evol
In this study, two freshwater gastropods (Bellamya aeruginosa and Pomacea canaliculata) were used as controls to study the differences in the effects of cyanobacteria on their gut microbial communities in ponds with the absence of cyanobacterial blooms. Cyanobacterial blooms cause distinct differences in the diversity, community structure, and assembly

Seasonal Variation in the β-Diversity of Periphytic Algae and Its Response to Landscape Patterns in the Chishui River, a Naturally Flowing Tributary of the Upper Yangtze River. [PDF]

Ecol Evol
Landscape fragmentation and complexity were key determinants of β‐diversity in algal communities. Effective biodiversity conservation requires comprehensive conservation efforts throughout the Chishui River basin. Ensuring a balanced distribution of habitat patch numbers and patch sizes is critical to maintaining the aquatic environment in the Chishui ...

An extended phylogenetic analysis reveals ancient origin of "non-green" phosphoribulokinase genes from two lineages of "green" secondary photosynthetic eukaryotes: Euglenophyta and Chlorarachniophyta

BMC Research Notes, 2011
Background Euglenophyta and Chlorarachniophyta are groups of photosynthetic eukaryotes harboring secondary plastids of distinct green algal origins. Although previous phylogenetic analyses of genes encoding Calvin cycle enzymes demonstrated the presence ...

Phagotrophic algae in a wastewater stabilization pond

International Journal of Aquatic Biology, 2018
In the course of evolution, phagotrophic euglenoids developed before the phototrophic species. Most phagotrophic euglenoids have a robust feeding apparatus.
