Molecular phylogeny and evolution of Parabasalia with improved taxon sampling and new protein markers of actin and elongation factor-1α [PDF]

, 2012
Background: Inferring the evolutionary history of phylogenetically isolated, deep-branching groups of taxa—in particular determining the root—is often extraordinarily difficult because their close relatives are unavailable as suitable outgroups.

The invertebrate Caenorhabditis elegans biosynthesizes ascorbate. [PDF]

, 2015
l-Ascorbate, commonly known as vitamin C, serves as an antioxidant and cofactor essential for many biological processes. Distinct ascorbate biosynthetic pathways have been established for animals and plants, but little is known about the presence or ...

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

The FEBS Journal, EarlyView.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

The Influence of Region, Sex, and Age on the Prevalence of Gastrointestinal Parasites in Alpacas (Vicugna pacos) in Poland

Animals
The aim of the study was to determine the extent and intensity of gastrointestinal parasite infections in alpacas (Vicugna pacos) in Poland, considering factors such as region, gender, age, and season.

Synchrony of Eukaryotic and Prokaryotic Planktonic Communities in Three Seasonally Sampled Austrian Lakes

Frontiers in Microbiology, 2018
Freshwater systems are characterized by an enormous diversity of eukaryotic protists and prokaryotic taxa. The community structures in different lakes are thereby influenced by factors such as habitat size, lake chemistry, biotic interactions, and ...

Differences in soil micro-eukaryotic communities over soil pH gradients are strongly driven by parasites and saprotrophs [PDF]

, 2016
A recent large-scale assessment of bacterial communities across a range of UK soil types showed that bacterial community structure was strongly determined by soil pH.

Houses made by protists [PDF]

Current Biology, 2011
What kind of structures are we talking about? Portable protective cases, known as tests, made by single-celled organisms out of collected building materials.What are the organisms that can do this? There are two distinct types of single-celled eukaryotes with this ability.

Compound‐Specific Stable Isotope Analysis Reveals Population‐Specific Differences in Chinook Salmon Trophic Level and Basal Resource Use in the Northeast Pacific

Fisheries Oceanography, EarlyView.
ABSTRACT Chinook salmon exhibit far‐flung and disparate population‐specific marine migrations that have made it difficult to assess their trophic ecology. In this study, we collected returning and resident subadult Fraser River Chinook salmon in 2018 and 2019 from population groups with different known run‐timings (spring, summer, and fall) and marine ...
