The redclaw crayfish: A prominent aquaculture species with invasive potential in tropical and subtropical biodiversity hotspots

Reviews in Aquaculture, Volume 13, Issue 3, Page 1488-1530, June 2021., 2021
Abstract The redclaw crayfish (Cherax quadricarinatus; hereafter redclaw), native to northern Australia and southern New Guinea, is among the largest freshwater decapods. It matures early and is considered highly prolific as females may lay over one thousand eggs in a single clutch.

How To Quantify a Genetic Firewall? A Polarity‐Based Metric for Genetic Code Engineering

ChemBioChem, Volume 22, Issue 7, Page 1268-1284, April 6, 2021., 2021
Quantifying the distance: If two organisms operate under different genetic codes, how likely is that they could still properly interpret each other's genes? We introduce a versatile metric to quantify the distance between the different genetic codes.

Functional Ecology of Two Contrasting Freshwater Ciliated Protists in Relation to Temperature

Journal of Eukaryotic Microbiology, Volume 68, Issue 1, January/February 2021., 2021
Abstract We conducted microcosm experiments with two contrasting freshwater ciliates on functional traits (FTs) related to their growth rate (numerical response, NR) and ingestion rate (functional response, FR) over a range of ecologically relevant temperatures.

Comparative genomics of a vertically transmitted thiotrophic bacterial ectosymbiont and its close free-living relative. [PDF]

Mol Ecol Resour
Abstract Thiotrophic symbioses between sulphur‐oxidizing bacteria and various unicellular and metazoan eukaryotes are widespread in reducing marine environments. The giant colonial ciliate Zoothamnium niveum, however, is the only host of thioautotrophic symbionts that has been cultivated along with its symbiont, the vertically transmitted ectosymbiont ...

Morphometric study of a Brazilian strain of Carchesium polypinum (Ciliophora: Peritrichia) attached to Pomacea figulina (Mollusca: Gastropoda), with notes on a high infestation

Zoologia (Curitiba), 2010
During an ecological study of the epibiotic relationship between ciliate protists and Pomacea figulina (Spix, 1827) (Gastropoda, Ampullariidae), originating from an urban stream in southeast Brazil, a high infestation by the peritrich ciliate Carchesium ...

Swimming of peritrichous bacteria is enabled by an elastohydrodynamic instability [PDF]

Scientific Reports, 2018
AbstractPeritrichously-flagellated bacteria, such as Escherichia coli, self-propel in fluids by using specialised motors to rotate multiple helical filaments. The rotation of each motor is transmitted to a short flexible segment called the hook which in turn transmits it to a flagellar filament, enabling swimming of the whole cell.

PERITRICHOUS FLAGELLA IN MESOPHILIC STRAINS OF AEROMONAS

Japanese Journal of Medical Science and Biology, 1985
A total of 186 mesophilic strains of Aeromonas, comprising 151 A. hydrophila and 35 A. caviae, were tested for peritrichous flagella by Leifson's staining method. When incubated on solid medium for 18 hr at 22 C, peritrichous flagella were demonstrated in 28 (18.5%) of the 151 strains of A. hydrophila and in 6 (17.1%) of the 35 strains of A.

Structure and dynamic of planktonic ciliate community in a large Neotropical river: the relevance of the pluviosity and tributaries in the biodiversity maintenance

Acta Limnologica Brasiliensia, 2017
Aim: We investigated the spatial and temporal patterns of abundance and diversity of planktonic ciliate community, in the last undammed stretch of the Upper Paraná River, Brazil.

Naturally Occurring Microbiota Associated with Mosquito Breeding Habitats and Potential Parasitic Species against Mosquito Larvae: A Study from Gampaha District, Sri Lanka

BioMed Research International, Volume 2020, Issue 1, 2020., 2020
A mosquito species has its own favourable requirements of abiotic and biotic characteristics including microbiota, in a breeding habitat. Some of the microbiota may cause parasitic or pathogenic effects to mosquito larvae such as species of viruses, parasitic bacteria, fungi, protists, entomopathogenic nematodes, and filamentous fungi.

Wall entrapment of peritrichous bacteria: a mesoscale hydrodynamics simulation study [PDF]

Soft Matter, 2020
Microswimmers such as E. Coli bacteria accumulate at walls. Mesoscale hydrodynamic simulations show an intriguing dynamics due to the interplay of hydrodynamic and steric interactions, and a pronounced wobbling motion.
