Summary: This study explores the evolution, ancestral ranges, and distributions of tarantulas, revealing a dual colonization of Asia by two distinct lineages at least 20 million years apart, as well as confirming a Gondwanan origin for the group. The current distributions of tarantulas are attributed to a combination of Gondwanan vicariance, continental rafting, and geographic radiation.

Summary: Research on the biogeographic history of mesic Australian fauna with Gondwanan origins is limited. This study focused on the burrowing clade of Australian freshwater crayfish to analyze their origin, distribution, and diversification patterns. The results suggest that the clade originated during the early fragmentation of Gondwana in southern Australia, with divergence between extant taxa likely a result of both short- and long-distance dispersal events, influenced by fluctuating sea levels and changing climate into the Eocene.

Summary: By sequencing nuclear genes and chloroplast regions of all species in the genus Paeonia, this study reveals that Paeoniaceae separated from Saxifragales in the late Cretaceous, diverged into woody and herbaceous clades in the late Oligocene, and dispersed from the Pan-Himalaya to East Asia, North America, Central Asia, and Europe. Multiple glacial cycles in Europe facilitated the hybridization and formation of allotetraploid species. A new taxonomic system with two subgenera and seven sections is suggested based on the phylogeny of Paeonia L.

Summary: Gerbillinae is the second largest subfamily in the Muridae family, consisting of approximately 16 genera and more than 100 species. Through genetic analysis, the phylogenetic placement of Ammodillus, a monotypic genus, has been elucidated for the first time, providing the most complete tribal phylogeny of Gerbillinae to date. The results support Ammodillus as a sister taxon to all other gerbillines and suggest its separation dates back to approximately 11.7 million years ago. The subfamily is divided into four tribes.

Summary: The disjunct distribution of plant clades between the southern and tropical Andes has not been well studied, with the hypothesis being that the global cooling trend in the Miocene and the concomitant aridification of certain regions played a crucial role in shaping this pattern. The climatic niches of these clades have shifted in different directions over time, rejecting the idea of niche conservatism.

Summary: The origin of anaerobic ammonium oxidation bacteria possibly dates back to the early Proterozoic era, and the Great Oxidation Event may have played a significant role in their emergence. The rising levels of atmospheric oxygen, making nitrite increasingly available, are believed to be the potential driving force behind the evolution of anaerobic ammonium oxidation bacteria.

Summary: Sengis are small mammals endemic to Africa, but their taxonomy and phylogeny have been difficult to resolve. This study generated the first phylogeny of all extant species using nuclear and mitochondrial DNA. Different parameters, such as the type of DNA and the inclusion or exclusion of fossil calibration points, were explored to assess their impact on age estimates. The findings showed that using mitochondrial DNA along with nuclear DNA or alone resulted in older ages and different branch lengths compared to using nuclear DNA alone. The study also highlighted the importance of considering the dataset used when interpreting dated phylogenies.

Summary: This study aims to investigate the origins and dispersal pathways of typhlopoids in India. Results indicate that Gerrhopilus is an ancient lineage, while the other three genera are more recent arrivals from Africa and Asia. Biogeographic reconstructions suggest an East Gondwanan origin for typhlopoids, with India harboring a combination of ancient and more recently dispersed lineages.

Summary: Recent transcriptomic studies of myriapod phylogeny have provided insights into the systematics and evolutionary relationships of myriapods. These studies support the division of myriapods into two major clades, Symphyla + Pauropoda and Chilopoda + Diplopoda, which contradicts traditional morphological groupings. Additionally, the relationships within chilopods and diplopods are largely consistent with morphology-based classifications, with some exceptions.

Summary: This study reconstructed the evolutionary history of Native American hawkweeds using molecular markers. It found that Chionoracium is a subgenus of the mainly Eurasian genus Hieracium, which originated from Eastern Europe about 1.58-2.24 million years ago. Chionoracium species colonized the New World through Beringia and formed distinct lineages in North and South America, contradicting traditional sectional classifications. Further taxonomic revision is recommended to elucidate speciation patterns.

Summary: Endozoochory, a mutualistic interaction between plants and frugivores, plays a key role in maintaining tropical biodiversity. A study comparing plant-seed disperser communities on a tropical island and mainland found that the island community was more asymmetric, connected, and nested. The interactions between plants and frugivores were not explained by phylogenetic relationships or functional traits, indicating the diffuse nature of these interactions.

Summary: This study aims to investigate the drivers of intra-specific genetic diversity in centipedes. By analyzing 1245 mitochondrial COI sequences from 128 centipede species, it was found that centipedes have high genetic diversity compared to other arthropods. Genetic diversity is associated with factors such as body size, geographic location, maternal care, and geographic distance among conspecifics.

Summary: The Western Ghats is a biodiversity hotspot with high diversity and endemicity of woody plants. The southern region of the Western Ghats acts as both a museum and cradle of evolutionary diversity, with a higher proportion of old and young lineages restricted to this area. The high geo-climatic stability and moist climate in the south contribute to the diversity gradient in this region.

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: 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.
