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 ...

Species diversity and ecological studies Euglenophyta in the Zayandeh Rood lake dam

تاکسونومی و بیوسیستماتیک, 2010
Zayandeh Rood Lake, as the largest Isfahan natural Lake, is located in the west of Isfahan city with the area of about 48 km2. Sampling of Euglenophyta was done in four stations from August 2005 through June 2006.

Euglenophyta, Xanthophyta, Chloromonadophyta

, 1973
This class comprises mainly motile unicells, although there is one small group of palmelloid, non-flagellated species. The organisms lack a cellulose cell wall but there is an external semi-rigid pellicle or periplast. This appears under the electron microscope as a well-differentiated layer of proteinaceous strips with helical symmetry, which in many ...

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.

Abteilung Euglenophyta (Euglenen, „Augentierchen“)

, 1987
Die Euglenophyta, eine relativ einheitliche Gruppe, umfassen eine einzige Klasse. Sie leben zum grosten Teil limnisch, kommen aber auch im Meer und auf feuchter Erde vor. Unter ungunstigen Bedingungen gehen die meisten Arten in ein Dauerstadium, das Palmella-Stadium, uber.

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.

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 ...

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
