Parasitic Infections of Freshwater Fish in Kenya: Prevalence Patterns, Ecological Drivers, and Implications for Aquaculture Sustainability. [PDF]

J Parasitol Res
Fish parasitic infections present a growing threat to freshwater aquaculture in Kenya, affecting fish health, reducing productivity, and limiting the economic potential of small‐scale and commercial farms. This review provides the first consolidated national checklist of freshwater fish parasites in Kenya, synthesizing evidence from lakes, rivers, and ...

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.

Medicinal and Aromatic Plant Oils in Aquafeeds: Mechanistic Perspectives on Growth Promotion, Immunomodulation, and Stress Resilience. [PDF]

Aquac Nutr
The aquaculture industry is increasingly transitioning toward sustainable aquafeeds, driven by the economic and environmental necessity to replace marine‐derived fishmeal and fish oil with plant‐ and insect‐based alternatives. This nutritional shift introduces physiological challenges, accelerating the search for natural, sustainable functional ...

Diversity of ‘simple’ multicellular eukaryotes: 45 independent cases and six types of multicellularity

Biological Reviews, Volume 98, Issue 6, Page 2188-2209, December 2023., 2023
ABSTRACT Multicellularity evolved multiple times in the history of life, with most reviewers agreeing that it appeared at least 20 times in eukaryotes. However, a specific list of multicellular eukaryotes with clear criteria for inclusion has not yet been published.

Diseases of the giant river prawn Macrobrachium rosenbergii: A review for a growing industry

Reviews in Aquaculture, Volume 15, Issue 2, Page 738-758, March 2023., 2023
Abstract The giant river prawn, Macrobrachium rosenbergii, is a major focus of aquaculture in tropical and sub‐tropical regions around the globe. Over the last 30 years, culture of M. rosenbergii has increased exponentially as demand has risen both for domestic consumption and for international export trade.

A global review of problematic and pathogenic parasites of farmed tilapia

Reviews in Aquaculture, Volume 15, Issue S1, Page 92-153, February 2023., 2023
Abstract Over the past 80 years, tilapia have been translocated globally for aquaculture; active production is recorded in >124 countries. Of 7 million tonnes of tilapia produced in aquaculture, 79% is from 79 countries outside the natural range of tilapia.

CARD‐FISH and prey tracer techniques reveal the role of overlooked flagellate groups as major bacterivores in freshwater hypertrophic shallow lakes

Environmental Microbiology, Volume 24, Issue 9, Page 4256-4273, September 2022., 2022
Summary Heterotrophic nanoflagellates (HNF) and ciliates are major protistan planktonic bacterivores. The term HNF, however, describes a functional guild only and, in contrast to the morphologically distinguishable ciliates, does not reflect the phylogenetic diversity of flagellates in aquatic ecosystems.

On the move: sloths and their epibionts as model mobile ecosystems

Biological Reviews, Volume 96, Issue 6, Page 2638-2660, December 2021., 2021
ABSTRACT Sloths are unusual mobile ecosystems, containing a high diversity of epibionts living and growing in their fur as they climb slowly through the canopies of tropical forests. These epibionts include poorly studied algae, arthropods, fungi, and bacteria, making sloths likely reservoirs of unexplored biodiversity.

A Reassessment of Phylogenetic Relationships in Class Oligohymenophorea (Protista, Ciliophora) Based on Updated Multigene Data. [PDF]

Ecol Evol
We report 97 new sequences, including SSU‐rRNA, ITS1‐5.8S‐ITS2 rRNA, LSU‐rRNA, mitochondrial cytochrome oxidase c subunit I, and mitochondrial small subunit ribosomal RNA genes of 30 oligohymenophorean populations. A comprehensive analysis of class Oligohymenophorea is conducted, encompassing 250 populations.
