Summary: The study reveals that density dependence can impact size-structured interactions among larval salamanders, with earlier-arriving species negatively affecting later-arriving species through predation and competition. Density-dependent effects reinforce asymmetric interactions among larval salamanders, with the intensity of the interactions also mediated by the arrival time and size of conspecifics.

Summary: The larval development of Pachypops fourcroi from the lower Amazon River was described in this study, focusing on morphological, meristic, and morphometric features. The larvae have an initially terminal mouth, which becomes subterminal with three barbels in the mentonian region throughout development. They can be differentiated from other Sciaenidae in the Amazon basin by their pigmentation pattern, presence of barbels, head depth, body depth and diameter, and shape of the eye.

Summary: Developmental maturation in larval zebrafish is associated with slow swimming behavior, particularly in older larvae who can maintain head stability during slow swimming. The MCoD neurons play a role in coordinating trunk muscle activities to produce the stable head and S-shaped swimming form. The ablation of MCoD neurons results in a change in swimming form and increased yaw displacement of the head.

Summary: A solid basis for addressing conservation challenges in amphibians requires increased knowledge of their natural history and biology. Recent research has found that reproductive modes in amphibians are more complex and varied than previously believed, but remain understudied. Detailed information on reproductive history is particularly important for filling current knowledge gaps.

Summary: This study assessed the effects of temperature on various aspects of early development in rainbow trout, including hatching, yolk-sac absorption, larval metamorphosis, post-metamorphic growth, developmental morphology, and muscle cellularity. The results showed that incubating the embryos at 16°C yielded synchronized hatching but smaller and less developed individuals compared to incubating them at 8°C. Shifting the post-hatch larvae to different temperatures affected the length and weight of the fish, with an immediate and temporary effect on length and a persistent effect on weight. Different temperature regimes also influenced the hypertrophy of red and white muscles. Overall, this study provides new insights into the temperature-dependent changes in developmental morphology, muscle cellularity, and larval growth in rainbow trout.

Summary: This study assesses the otolith growth and microstructural features of Sinogastromyzon wui larvae and juveniles. It finds that the lapilli otolith is the most suitable for age determination and increment deposition rate confirmation. The shape changes of the sagittae otolith are closely related to fish ontogenesis. The findings support the use of lapillus increment deposition rate and the timing of the first daily increments for age determination of wild larval and juvenile S. wui.

Summary: The study analyzed muscle development in pikeperch during its developmental stages and investigated the transcriptomic regulation of muscle tissue. Three different phases of myogenic gene expression were observed during embryonic and larval development. This research contributes to a better understanding of pikeperch myogenesis and can aid in the rearing of pikeperch in aquaculture.

Summary: Understanding the biology of early life stages of marine fish is crucial for revealing factors affecting survival and recruitment strength. This study described the embryonic and larval development of the Peruvian anchovy under captive conditions, showing significant temperature effects on size-at-hatch. Larvae began feeding on small dinoflagellates at 3 days post-hatch, transitioning to zooplankton at 7 days post-hatch, with increased activity and schooling observed at 31 days post-hatch. Temperature influenced size-at-age, but not body shape.

Summary: Understanding the early life histories of keystone marine herbivores, such as the long-spined sea urchin, can provide valuable insights into population dynamics and ecosystem functioning. This study characterized the morphological attributes preceding metamorphosis of feeding larvae and examined the factors influencing the development of these attributes. The results revealed the role of nutritious microalgae in promoting metamorphic competence and the influence of different cues on settlement. These findings improve our understanding of habitat selection and recruitment potential in the long-spined sea urchin, and can be applied to enhance population dynamics models and aquaculture production methods.

Summary: This study investigated the taxonomy of the crustose lichen genus Calvitimela using molecular phylogenetics and morphological observations. The results revealed evolutionarily old and deeply divergent lineages within Calvitimela, with overlapping morphological characters between different subgenera. Chemical characters were informative at the level of subgenera but often homoplastic at the species level. A practical taxonomy of Calvitimela was proposed based on these findings.

Summary: This study investigates the evolutionary history and speciation mechanisms of montane potamids in the Hengduan Mountains Region. The results suggest that the vicariance events of these crabs are correlated with the emergence of sky islands due to the uplift of the mountains. The mountain ridges provided corridors for their dispersal and past climatic conditions played a crucial role in their evolutionary history. The mechanisms isolating sky islands are reinforced by the climatic features of dry-hot valleys and continue to affect local diversification.

Summary: Species delimitation of European blind mole rats is challenging due to their small morphological differences and complex chromosomal evolution. This study provides a comprehensive framework to improve understanding of their evolutionary history and revise their taxonomy. The results reveal the presence of multiple superspecies and species, with distinct geographic patterns and rapid chromosomal evolution.

Summary: This study investigates the phylogenetic relationships among patellogastropod families using mitochondrial and phylogenomic data. The results show that the mitochondrial phylogeny recovers monophyly of most families, but the relationships among families are still contentious. However, a more robust family-level topology consistent with morphology is achieved by phylogenomics. Additionally, the mainly deep-water families are found to be monophyletic, suggesting a single colonization of the deep water during the Jurassic.

Summary: Despite numerous studies on hybrid speciation, our understanding of this process remains limited. In this study, we conducted an 18-year systematic investigation on Populus taxa on the Qinghai-Tibet Plateau and discovered three new taxa that originated from distant hybridization between two different sections. These hybrid taxa demonstrate greater ecological adaptability than their ancestral species due to heterosis. We propose a hybrid speciation process model that can explain important evolutionary concerns.

Summary: Unlike conspicuous ochrophytes, many small and overlooked flagellates belonging to basally branching stramenopiles remain poorly characterized at the cellular or genomic level. This study describes four new species, including two new genera, of sediment-dwelling MAST-6 and provides updated phylogenomic tree of stramenopiles. The characterization of these flagellates is important due to their phylogenetic diversity and abundance in various environments.

Summary: Phylogenomic conflicts are widespread among genomic data, with most previous studies primarily focusing on nuclear datasets instead of organellar genomes. In this study, we investigated the phylogenetic conflicts within and between plastid and mitochondrial genomes using Potentilla as a case study. We found that both plastid and mitochondrial genomes divided Potentilla into eight highly supported clades, with two newly identified clades. Our results demonstrate that mitochondrial genes can fully resolve phylogenetic relationships among major clades of Potentilla and are not always linked with plastomes in evolutionary history.

Summary: Traditionally, differences between species have been associated with morphological variation. However, the discovery of cryptic diversity suggests that the evolution of distinct lineages can occur without morphological differences. Through genetic analysis, we found that a tropical montane plant lineage is composed of numerous unrecognized genetic groups that are not morphologically distinct. Geographic distance and topography play a crucial role in determining the genetic divergence of these groups.
