Summary: Fish are affected by environmental variables and show physiological responses to maintain homeostasis. Xiphophorus maculatus can acclimatize and reproduce in saltwater, with offspring surviving when adults are gradually acclimatized to different salinities. Abrupt exposure to high salinity can be a stressor causing mortality.

Summary: Genetic and morphological variation within Xiphophorus hellerii populations are influenced by geographic and environmental factors, with body shape variations possibly linked to temperature. The study suggests that X. hellerii from different basins and hydrological regions have followed independent evolutionary routes.

Summary: The acute exposure of swordtail fish to microplastics was found to have adverse effects on their liver, leading to changes in metabolic profiles involving multiple metabolic pathways and metabolites. Microplastics affected oxidative stress, immune function, energy metabolism, sugar metabolism, lipid metabolism, and other physiological processes, as well as feed utilization, growth performance, nutrient metabolism, and animal growth. Additionally, a dose-effect relationship was observed between the quantity of microplastics and the number of affected amino acids.

Summary: During mate choice, receivers can respond to signals non-linearly, for example through proportional processing. This study on female green swordtail fish demonstrated that preferences for larger males were better predicted by the proportional difference between males rather than the absolute difference. This suggests that receiver perception of visual signals may play a role in selecting against the evolution of ever-larger signalling traits.

Summary: The aim of this study was to evaluate the impact of different concentrations of canthaxanthin on the red colour of the blood swordtail fish. Six concentrations of canthaxanthin were used and fish were evaluated using photographs and imaging applications. No significant differences were observed in productive performance. The red pigmentation of the swordtail fish did not increase significantly regardless of canthaxanthin dosages, possibly due to the storage capacity of carotenoids.

Summary: The study investigated the effects of different light sources and carotenoid levels on ornamental fish swordtail, with results showing better performance in fish fed with astaxanthin and reared under artificial light. The interaction between carotenoid dosage, type, and light source also played a significant role in the growth and reproductive performance of the fish.

Summary: The mating behavior of Alfaro cultratus, a knife livebearer, is described in detail. The male swims above the female and repeatedly touches the dorsal part of female head with the pelvic fin tips during rubbing. This courtship behavior, involving pelvic fin male-female contact, is reported for the first time in poecilids. Based on preliminary evidence, it is proposed that a sensory bias mechanism may play a role in the evolution of signal design/mate choice in this species, which needs further testing.

Summary: This study revealed the presence of a self-sustained population of X. hellerii in Bulgaria and Europe, indicating that climate change and warmer winters are facilitating its acclimatization and increasing the potential for colonizing new habitats, posing a high risk of becoming the next new invasive species in Southern Europe.

Summary: This study investigated parasitic infections in variable platyfish and eastern mosquitofish from earthen ponds in west central Florida. The researchers identified Huffmanela cf. huffmani as the parasite infecting the swim bladder, gonad, and visceral peritoneum. They found that the nucleotide sequences of H. cf. huffmani were identical in both fish species. Pathological changes were observed, including inflammation and tissue necrosis, which could impact the organ function of the swim bladder.

Summary: This study analyzes the genetic characteristics and phylogeographic relationships of Goodea, a widely distributed and environmentally tolerant genus of goodeids. The research reveals low genetic differentiation and shared haplotypes in some regions, as well as geographic segregation and isolated groups. Additionally, Bayesian Skyline Plot analysis indicates recent population expansion in certain regions for Goodea atripinnis.

Summary: Among fishes in the family Poeciliidae, visual signals are crucial for mate choice and male-male competition. While anatomical acuity appears similar in male and female green swordtails, behavioral assays demonstrate a significant difference in acuity, with females displaying higher acuity than males.

Summary: The study found that females from high-predation environments of Alfaro cultratus have significantly lower reproductive allotment compared to females from low-predation environments, but there are no significant differences in terms of offspring number or size at maturity for both males and females. Additionally, the species exhibits isometric patterns of allocation for clutch dry mass in relation to female dry mass in both high-predation and low-predation environments.

Summary: The studies reviewed in this article show that roads have the strongest negative effect on connectivity resistance for anurans in temperate regions. Urbanization, fragmentation, and land cover change into agriculture and grasslands also provide resistance to connectivity for anurans worldwide. In both temperate and tropical regions, rivers are the most important natural element negatively affecting connectivity, while streams and forests cover promote connectivity in all regions. This highlights the importance of considering landscape genetics in conservation plans for anuran species.

Summary: The study found that dewlap colors of Amazon Slender Anoles vary among populations, but are not segregated in environmental space and show no support for optimized signal transmission at a local scale. Certain phenotypes are negatively associated with sympatric Anolis species with similar dewlap color attributes, suggesting interactions with closely related species promoted dewlap divergence among A. fuscoauratus populations.

Summary: The study aims to uncover convergent and divergent patterns of diversification in Anolis lizards on the Greater Antillean islands and in Central and South America. It found that mainland Anolis exhibit similar ecologies and morphologies to those on the islands, suggesting exceptional morphological convergence between the island and mainland faunas. However, regional differences and historical contingencies can lead to replicate yet variable radiations, indicating that replicated radiations occur more frequently beyond island settings than previously recognized.

Summary: Structural variations, including changes in copy number, orientation, or location, play a significant role in genetic hearing loss, with copy number variants (CNVs) comprising a substantial proportion of cases. This review summarizes methods for detecting CNVs in genes associated with hearing loss and compiles data on CNVs in hearing loss genes, emphasizing their importance in diagnosis and potential gene therapies.

Summary: Gene flow and reticulation play important roles in the diversification of taxonomic groups. In this study on Anolis lizards, we discovered a reticulated species and inferred the phylogeny of the group. Our findings suggest that the genomic data violate assumptions of the coalescent model, and the reticulation event may have facilitated adaptive evolution.

Summary: This retrospective case review evaluated the rate of preserved vestibular function in pediatric cochlear implant surgery. The results showed a higher rate of preservation of vestibular function in children after cochlear implantation, possibly due to contemporary, less traumatic electrodes and insertion techniques. Further study is needed to explore the impact of different cochlear implant electrode designs and insertion approaches on post-operative vestibular preservation.
