Chemical communication in cichlids: A mini-review.
TLDR
The aim of this mini-review is to persuade those working with cichlids to consider the involvement of chemical communication, and those working in chemical communication to consider using cichLids.
Identity of a Tilapia Pheromone Released by Dominant Males that Primes Females for Reproduction
TLDR
The identified urinary steroids prime the female endocrine system to accelerate oocyte maturation and possibly promote spawning synchrony and identify a male Mozambique tilapia urinary sex pheromone as two epimeric (20α and 20β-) pregnanetriol 3-glucuronates.
Genomic Insights into Aquimarina sp. Strain EL33, a Bacterial Symbiont of the Gorgonian Coral Eunicella labiata
ABSTRACT To address the metabolic potential of symbiotic Aquimarina spp., we report here the genome sequence of Aquimarina sp. strain EL33, a bacterium isolated from the gorgonian coral Eunicella…
Bioactive Secondary Metabolites from Octocoral-Associated Microbes—New Chances for Blue Growth
TLDR
To extend knowledge and foster the near-future laboratory production of bioactive compounds from (cultivatable and currently uncultivatable) octocoral symbionts, optimal blending between targeted metagenomics, DNA recombinant technologies, improved symbiont cultivation, functional genomics, and analytical chemistry are required.
Muscular hypertrophy of urinary bladders in dominant tilapia facilitates the control of aggression through urinary signals
TLDR
The results suggest that the larger, more muscular bladder of dominant males is an adaptation, facilitating higher urination frequency, post-renal modulation and storage of larger urine volumes for longer.
Evidence for Selective Bacterial Community Structuring in the Freshwater Sponge Ephydatia fluviatilis
TLDR
This study supports the contention that the composition and diversity of bacteria in E. fluviatilis is partially driven by the host organism and ascertained the status of two alphaproteobacterial lineages as freshwater sponge-specific phylogenetic clusters.
Metagenomic insights into the taxonomy, function, and dysbiosis of prokaryotic communities in octocorals
TLDR
It is argued that host-symbiont recognition, abiotic-stress response, micronutrient acquisition, and an antiviral defense arsenal comprising multiple restriction endonucleases, CRISPR/Cas systems, and phage lysogenization regulators are signatures of prokaryotic communities in octocorals.
Genomic blueprints of sponge-prokaryote symbiosis are shared by low abundant and cultivatable Alphaproteobacteria
TLDR
A low-carbon based strategy is used to cultivate low-abundance bacteria from Spongia officinalis that possesses several genomic attributes common to dominant, presently uncultivatable sponge symbionts, potentially contributing to host fitness through detoxification mechanisms and nutritional exchange.
The gorgonian coral Eunicella labiata hosts a distinct prokaryotic consortium amenable to cultivation
TLDR
The E. labiata microbiome is diverse, distinct from seawater and enriched in (gorgonian)‐specific bacterial phylotypes, opening new avenues to study coral‐microbe interactions.
A Multi-Component Pheromone in the Urine of Dominant Male Tilapia (Oreochromis mossambicus) Reduces Aggression in Rivals
TLDR
It is concluded that P3Gs alone have no reducing effect on aggression and that the urinary signal driving off male competition is likely to be a multi-component pheromone, with components present in both the polar and non-polar urine fractions.
