Summary: A new genus and species of brown algae, Setoutiphycus delamareoides gen. & sp. nov., was described in this study. This species, similar to Delamarea but distinct in certain aspects, was found in the Seto Inland Sea. It is suggested that the species may have survived in refugia in southern Japan during the last glacial maximums, rather than evolving within the Seto Inland Sea itself.

Summary: Colpomenia borea sp. nov. was described based on morphological observations and molecular analyses using mitochondrial cox3 and chloroplast rbcL genes. It is distinguished from other Colpomenia species by its small globular to ovoidal thallus and thin thallus membrane. C. borea is epiphytic on the brown alga Stephanocystis in protected areas. The phylogenetic analysis showed that C. borea is a distinct species, closely related to C. peregrina.

Summary: This study aimed to identify dermatophyte isolates through phenotypic and genotypic methods and determine their phylogenetic relationships. The isolates were classified into different genera based on their morphological characteristics, and genotypic analysis revealed the most frequent species. The study demonstrated the usefulness of genotypic markers for phylogenetic analysis of dermatophytes.

Summary: The study found that flocking in bird species can be reasonably predicted by a set of ecological and life history variables related to food distribution and abundance, and predation risk. Flocking is more prevalent in species with a plant diet, aquatic species, and species with fast life histories.

Summary: This study reports the first occurrence of Sporochnus dotyi Brostoff, a brown algal species, in Kushimoto, Kii Peninsula, Japan. The genetic analysis showed that this alga has an identical partial rbcL sequence to S. dotyi from Hawaii, indicating they belong to the same species.

Summary: A new species Lobophora tsengii is described from Bach Long Vy (Bailongwei) Island, Haiphong Province, Vietnam, with morphological similarities to plants from Hainan Island, China. Molecular phylogenetic analyses show that the specimens from the island form a clade separated from other Lobophora species.

Summary: Understanding local-scale patterns of species persistence or extirpation in the Anthropocene is a challenge in conservation ecology. This study examined mammal species in the Neotropical realm and found that habitat loss was the main driver of local extinctions, while hunting also had a significant impact on many species. Additionally, body size played an important role in local extinctions.

Summary: A new species of Pristionchus was isolated from wood-decaying fungus Trametes orientalis in Kyoto, Japan. Despite similarities to P. elegans and P. bucculentus, the new species can be distinguished by its characteristic stomatal morphology and male and female tail characters. Phylogenetic analysis suggests a close relationship between the new species and the aforementioned species.

Summary: Research shows that under limited resources, most bacterial taxa can survive, with a wide range of extinction times. Despite the lack of exogenous resources, bacterial populations continue to evolve and acquire numerous mutations. While adapting to environmental pressures, bacterial lifespan is extended through scavenging dead cells.

Summary: The taxonomic status and species diversity of the brown algal genus Padina were assessed based on DNA sequences and morpho-anatomy, revealing the presence of four distinct new species. The phylogenetic analyses provided insights into the biogeographic characteristics of Padina, with species in the Pacific Ocean showing shared distributions. Molecular time trees indicated an estimated divergence time for the genus Padina in the mid-Cretaceous.

Summary: The molecular phylogeny study shows that Pilinia rimosa is phylogenetically distant from the Ectocarpales. Cultures of P. rimosa exhibit a direct type of life history with reproduction by characteristic unilocular zoidangia. The establishment of a new family Piliniaceae for Pilinia and its placement in Ishigeales is proposed.

Summary: Understanding the factors driving diversification of taxa is important in macroevolutionary research. Although the relationship between molecular evolution and diversification has received less attention, correlations between rates of molecular evolution and diversification rate have been observed in various taxa. This correlation has implications for evolutionary theories and could impact evolutionary rate and timescale inference.
