Abstract
Reproduction involves multiple complex behaviours, and the effects of familiarity on such social interactions are seldom described in fish. This is particularly true for sound production and communication within aggressive or non-aggressive context. This study explores the effects of a common garden rearing without parental care of two closely related cichlid species (Nile tilapia Oreochromis niloticus and black-chinned tilapia Sarotherodon melanotheron) on their sound production features and social interactions. After 9 months in common garden rearing, from embryonic stage to first maturity, sound production and associated behaviours were recorded on specimens of the two species in intraspecific and interspecific pairings. The authors found that fish were able to produce the same kind of sounds as those recorded in similar context for their parents. Drum sounds were associated to chasing, lateral attack and courtship in O. niloticus and only to fleeing or avoidance in S. melanotheron. Specific grunts were produced in chasing, after biting and in nest building by O. niloticus, and specific rolling sounds were associated to courtship in S. melanotheron. Sound production and behaviours were not correlated to sex steroid levels, but the number of sounds recorded in aggressive context was correlated to dominance in O. niloticus. The authors conclude that one generation of common garden rearing does not modify sound features, which remain specific and innate in the two cichlids. Despite the familiarity, O. niloticus remained dominant on S. melanotheron, but the aggressiveness between the two species decreased.

Abstract
In ancient freshwater lakes, an abnormally large species diversity is observed. The mechanisms that generated
extremely high biodiversity in the ancient lakes have not been sufficiently studied and remain only partially
known. Sequences of environmental changes in highly complex ecosystems such as Lake Baikal, may induce sophisticated
combinations of microevolutionary processes. These processes are likely to result in unusual “patterns” of
genetic variability of species. The most unusual patterns include the ones when speciation is followed by incomplete
lineage sorting as well as mitochondrial or nuclear introgression. All these phenomena are diagnosed by comparing
the topologies of phylogenetic trees inferred from molecular markers of evolution located in mitochondria and
nuclei. Mitochondrial and nuclear introgression is a particularly interesting and complex case, which is the process of
incorporating the gene alleles of one species into the gene pool of a sister species due to interspecific hybridization
(introgressive hybridization). In many cases, existing methods for molecular phylogenetic analysis do not automatically
allow the observed patterns of polymorphism to be explained and, therefore, cannot provide hypotheses that
would explain the mechanisms which resulted to these patterns. Here we use adaptive dynamics models to study
neutral molecular evolution under various scenarios of interaction between sister species and the environment. We
propose and justify a set of criteria for detecting how two evolutionary trees may differ, with a special focus on comparing
a tree inferred from nuclear DNA to one from mitochondrial DNA. The criteria react to branching pattern and
branch lengths, including relative distances from ancestral lineages. Simulations show that the criteria allow fast and
automated detection of various types of introgression, secondary breaches of reproductive barriers, and incomplete
lineage sorting.

Neurogenomic Profiling Reveals Distinct Gene Expression Profiles Between Brain Parts That Are Consistent in Ophthalmotilapia Cichlids. Front Neurosci 2018; 12:136.

Abstract
The detection of external and internal cues alters gene expression in the brain which in turn may affect neural networks that underly behavioral responses. Previous studies have shown that gene expression profiles differ between major brain regions within individuals and between species with different morphologies, cognitive abilities and/or behaviors. A detailed description of gene expression in all macroanatomical brain regions and in species with similar morphologies and behaviors is however lacking. Here, we dissected the brain of two cichlid species into six macroanatomical regions. Ophthalmotilapia nasuta and O. ventralis have similar morphology and behavior and occasionally hybridize in the wild. We use 3′ mRNA sequencing and a stage-wise statistical testing procedure to identify differential gene expression between females that were kept in a social setting with other females. Our results show that gene expression differs substantially between all six brain parts within species: out of 11,577 assessed genes, 8,748 are differentially expressed (DE) in at least one brain part compared to the average expression of the other brain parts. At most 16% of these DE genes have |log2FC| significantly higher than two. Functional differences between brain parts were consistent between species. The majority (61–79%) of genes that are DE in a particular brain part were shared between both species. Only 32 genes show significant differences in fold change across brain parts between species. These genes are mainly linked to transport, transmembrane transport, transcription (and its regulation) and signal transduction. Moreover, statistical equivalence testing reveals that within each comparison, on average 89% of the genes show an equivalent fold change between both species. The pronounced differences in gene expression between brain parts and the conserved patterns between closely related species with similar morphologies and behavior suggest that unraveling the interactions between genes and behavior will benefit from neurogenomic profiling of distinct brain regions.
