Vorticella sp: Prospective Mosquito Biocontrol agent

Journal of Arthropod-Borne Diseases, 2016
Background: Considering the disadvantages of chemical insecticides, we aimed to evaluate Vorticella parasites for control of mosquito larvae of Anopheles stephensi and Aedes aegypti at different larval stages.

Peritrichs (Ciliophora, Peritrichia) in the Danube: Keystone Organisms in the Formation of Diverse Protist Biofilms. [PDF]

Environ Microbiol Rep
Colonial peritrichs act as physical ecosystem engineers in middle Danube biofilms, generating three‐dimensional structures during 1–28 days of colonisation. Their surfaces host filter feeder epibionts (choanoflagellates, other peritrichs, rotifers), expanding filtration capacity and promoting functional group establishment including swimming and ...

From Mud to Meat: Comparative Metabarcoding Reveals Two Different Evolutionary Paths to Carnivory in a Group of Meiofaunal Annelids. [PDF]

Mol Ecol
ABSTRACT Evolutionary transitions to carnivory represent profound shifts in feeding mode that are often accompanied by widespread changes in organismal function, behaviour and ecology. Such transitions have evolved numerous times among animals, and predator–prey interactions have been major drivers of animal evolution.

Self-Oscillating Helix Showing Amplified Winding and Unwinding Motions. [PDF]

Adv Mater
The hydrogel helix exhibits autonomous oscillation synchronized with the Ru(bpy)32+/3+ redox cycle in the Belousov–Zhabotinsky reaction. Periodic winding–unwinding accompanies magnified motion along one direction within the gel phase. ABSTRACT Helical architectures in nature amplify motion via winding–unwinding.

Widespread Association of Ciliates Colonizing Gills of Shrimps Inhabiting Vents and Seeps Across the Pacific Ocean. [PDF]

J Eukaryot Microbiol
ABSTRACT Bacterial symbiosis is well‐documented in chemosynthesis‐based ecosystems, but associations with microeukaryotes remain overlooked. In this study, using scanning electron microscopy and 18S rDNA barcoding, we investigate the presence, diversity, and biogeographic patterns of ciliate epibionts associated with two deep‐sea caridean families ...

DNA Metabarcoding as a Tool to Study Plankton Responses to Warming and Salinity Change in Mesocosms. [PDF]

Ecol Evol
To assess the impact of future climate change on Baltic Sea plankton communities, we conducted a mesocosm experiment manipulating temperature and salinity, using both microscopy‐based and DNA metabarcoding for plankton identification. Our results show that warming primarily influenced lower trophic levels, increasing community evenness and favouring ...

A Pilot Investigation of the Hidden Communities Associated With Dryas octopetala L. (Rosaceae) in Svalbard Using DNA Metabarcoding. [PDF]

Environ Microbiol Rep
A single marker revealed a considerable diversity of organisms associate with Dryas octopetala. The rhizosphere contains more taxa than the phyllosphere. Some taxa are cited for the first time in the Svalbard Archipelago. The use of different DNA marker will increase diversity data in the Svalbard Archipelago.

Evaluation of Yellow Mealworm (<i>Tenebrio molitor</i>) Larvae Meal as a Carbon Source in Biofloc System for Dwarf Crayfish (<i>Cambarellus montezumae</i>) Culture. [PDF]

Aquac Nutr
The aim of this study was to evaluate the use of Tenebrio molitor larvae meal as a carbon source in a biofloc system (BFT) to optimize the culture of C. montezumae. A trial was conducted for 24 weeks, 500 T. molitor larvae were reared with wheat bran as substrate, and hydration once a week; at the end, 9000 T.

Prevalence and intensity of ectoparasites in giant freshwater prawn: Implications for aquaculture [PDF]

Iraqi Journal of Veterinary Sciences
The giant freshwater prawn (GFP) is highly susceptible to ectoparasite infestations, particularly under suboptimal management conditions. This study investigates the prevalence and intensity of ectoparasites on various prawn body parts, including the ...
