Summary: This study investigates the importance of skull and jaw shape in animal feeding and explores the genetic basis of facial variation. The researchers found that changes in craniofacial structure, especially in the lower jaw and throat region, impact how animals perform suction feeding and biting. They also identified genetic regions that regulate these facial shapes, suggesting the involvement of sensory evolution in facial evolution. Despite facial shapes being controlled by distinct genetic regions, cichlids with similar feeding methods exhibit similar facial shapes, indicating that jaw movement function imposes limits on facial evolution in these fishes.

Summary: This study compared the shape of viscerocranial bones among different Tropheus populations and found significant morphological differences between sympatric and non-sympatric populations, as well as extensive variation within and among species. Sexual dimorphism was also evident in the viscerocranial bones analyzed. The study suggests that differences in ecologically relevant traits, such as bones of the preorbital region, play an important role in the process of niche separation and cichlid fishes diversification.

Summary: The research found that plasticity is generally integrated across a range of ecologically relevant traits, with traits that have overlapping functions responding in a coordinated manner. Genetic data suggest a compromise between global genetic regulators and integration across traits for plasticity.

Summary: Lake Malawi cichlid fishes exhibit extensive phenotypic diversity despite low sequence divergence. The study reveals substantial methylome divergence among closely-related cichlid fishes, with differentially methylated regions associated with transcription changes of ecologically-relevant genes. This research provides insights into the role of epigenetics in species diversification.

Summary: This study compared two closely related Neotropical cichlid fish lineages using 40 resequenced genomes and two de novo assembled genomes. Despite inhabiting similar ecological environments, the evolutionary outcomes of the two lineages were markedly different.

Summary: This study explored the response capabilities of a Geophagini cichlid to changes by exposing it to different substrate types. Significant differences were found in shape and disparity, except for the epibranchial lobe which exhibited more modular variation. This research offers insights into how Geophagini cichlids may respond to environmental change and further contributes to our understanding of the functional morphology of winnowing foraging behaviors.

Summary: Cichlid fishes exhibit rapid, extensive, and replicative adaptive radiation in feeding morphology. Plasticity of the cichlid jaw has also been well documented, and the crocc2 gene is identified as a novel mediator of bone formation, plasticity, and evolution. The fixation of environmentally sensitive genetic variation drives evolutionary divergence along a phenotypic axis established by the initial plastic response.

Summary: In this study, a method for quantifying rice panicle organ distribution patterns was developed and integrated into a QTL analysis, revealing that the major QTL for organ number, Gn1, is not associated with distribution pattern. This study provides insight into rice panicle organ distribution patterns that will help improve breeding targeting rice panicle architecture.

Summary: This study examines the impact of intersexual niche differentiation on multiple morphological structures in roundfin Telmatherina, the first case where such differentiation was demonstrated in an adaptive fish radiation. The results show that sexual dimorphism in two out of three morphospecies affects several components of the head, likely for adaptive purposes. These differences are linked to species-specific ecology and influence various axes of variation. The study suggests that intersexual variation contributes to the adaptive diversity of roundfins and may play a key role in minimizing intersexual competition in emerging radiations.

Summary: In this study, newly discovered evolutionarily significant populations of Korogwe tilapia from southern Tanzania are threatened by hybridization with invasive Nile tilapia. Genetic analysis shows distinct differences between southern and northern populations of O. korogwe, with evidence of hybrids in southern lakes. This highlights the need for conservation interventions to protect these unique genetic resources.

Summary: This study presents an updated time-calibrated phylogenomic hypothesis to investigate the diversification of pythons in the Australo-Papuan region. The results show that pythons experienced sudden speciation rates and accelerated phenotypic evolution following their invasion of this region, providing evidence for adaptive radiation theory. This study highlights the importance of studying diverse adaptive diversification systems in understanding biodiversity generation.

Summary: The study utilized a landmark-free method to characterize the craniofacial skeletal phenotype of two mouse models and found dysmorphologies in one model and variation attributed to size and sexual dimorphism in another. The landmark-free method outperformed the landmark-based method in pinpointing local differences and structural reductions, making it suitable for wider application, especially in developmental mutant phenotype characterization.

Summary: This study constructed two F-2 populations using the DM-resistant accession PI 442177 and mapped QTLs conferring DM resistance. A high-density genetic map was generated and a major QTL DM9.1 was consistently detected at different growth stages. QTL-seq analysis validated the presence of DM9.1 and a KASP marker co-segregating with DM9.1 was successfully developed, providing valuable information for DM-resistant gene cloning and melon DM-resistant breeding programs.

Summary: This text provides a detailed examination of the adaptive radiation of cichlid fishes in Lake Tanganyika, demonstrating empirical support for two theoretical predictions of how adaptive radiations proceed and revealing a positive correlation between species richness and per-individual heterozygosity. The study highlights the rapid morphological diversification through trait-specific pulses of accelerated evolution within the confines of the lake.

Summary: This study evaluates the accuracy of a statistical method for estimating missing shape data. The results indicate that the method can accurately estimate the original anatomical data, especially when the damage is small, but the error increases significantly with increasing damage size.
