Summary: DNA barcoding and metabarcoding are widely used for species discovery and biodiversity assessments, but high error rates can inflate estimates. The debar package utilizes a hidden Markov model to denoise COI sequences, reducing indel errors and being sensitive to true COI variation in the animal kingdom. This results in more accurate sequences and aids in characterizing species diversity.

Summary: This study explores the species boundaries and phylogeny of Phrynarachne spiders in China, identifying six species and providing insights into their evolution and divergence times. The results show that Phrynarachne spiders in China have a monophyletic relationship and belong to the higher 'Thomisus group'. The estimated crown age of this genus in China is in the middle Miocene.

Summary: Two new species of aphids were described, Aphis (Toxoptera) fafuensis and Aphis (Toxoptera) sennae, which feed on Adinandra millettii and Senna bicapsularis, respectively, in China. Morphological and molecular data supported the taxonomic classification of these new species within the subgenus Aphis (Toxoptera). A key for identifying apterous viviparous females of this subgenus was provided.

Summary: The current research effort used DNA barcode analysis to confirm and authenticate the identity and interrelationship of Morus species. Chloroplast DNA of specimens were evaluated through PCR, sequence homology, and NJ clustering. The results showed that rbcL and matK markers can efficiently distinguish between species, and the research could be useful for identifying other species of Morus and contribute to the taxonomy of the genus.

Summary: This study aimed to provide genetic data of Mansonia, a mosquito species that is an important vector of viruses and other parasites. The morphological identification of this species is difficult, and the DNA sequences obtained in this study can be used for molecular identification. The cytochrome c oxidase subunit I (COI) DNA barcode region is considered a valuable and reliable tool for mosquito species recognition. This research provides tools for the genetic identification of species that play a significant role in pathogen transmission.

Summary: Taxonomic studies based on molecular markers led to the description of a new species, Hypnea pseudomusciformis, which accommodates three morphologically divergent species with identical DNA barcode sequences found on the coast of Brazil. Further phylogeographic studies showed that H. pseudomusciformis is divided into three distinct haplotype groups related to different floristic provinces along the Brazilian coast.

Summary: This study analyzed the effects of increased temperature and salinity on two species of macroalgae. The research found that both temperature and salinity increase can cause a decrease in algal growth. Additionally, the macroalgae synthesized proteins, carbohydrates, and antioxidants to adapt to detrimental temperatures and salinities. The study also revealed that the macroalgae adjusted their pigment contents under thermal and saline stress.

Summary: DNA sequence analysis reveals that the current classification of Gelidium is not monophyletic, with three distinctive lineages. A new genus, Gelidiorariphycus, is described to accommodate one of these lineages. The species in this genus have similar morphologies and primarily grow on shallow subtidal rocky shores.
