Summary: Red algal parasites are highly host specific organisms that are morphologically reduced with decreased pigmentation. Molecular data have repeatedly demonstrated that red algal parasites often resolve within the same genus as their hosts, rather than forming a monophyletic parasitic genus.

Summary: This study addresses the taxonomic delimitation issue in the Monostroma and Gayralia genera of monostromatic green algae using morphology and DNA analysis. The findings suggest that the genetic distance between Monostroma and Gayralia is smaller than the genetic distance within the Monostroma genus. The specimens share similar morphology but differ in thallus thickness and size.

Summary: This study analyzed the floral variation of Vanilla pompona collections from different localities in Mexico and found significant differences among collections and localities. Six morphotypes were identified, and the variation was associated with factors such as environment, geographic barriers, and pollinator pressure. The study also observed variation in flowering periods in one locality.

Summary: This study examined populations of Dendrobium kingianum across different regions using field observations, morphometric analysis, and nrITS sequences. It identified morphological variations within D. kingianum, suggesting a single species with clinal variation. The nrITS gene tree revealed two subgroups within D. kingianum subsp. kingianum, as well as the disjunct subsp. carnarvonense in central west Queensland. The study provided regional descriptions documenting clinal variation and clarified the relationship between different varieties within D. kingianum.

Summary: The study isolated Alternaria fungi from infected tomato fruits using baiting technique and confirmed their species through morphological identification and gene sequencing. It was found that four out of five Alternaria species produced mycotoxins, with Alternaria alternata being the most active species, producing three types of toxins.

Summary: This study analyzed the infraspecific variation of the ITS rDNA region of brown Parmeliae in Poland and compared it with non-molecular characters. Haplotype networks were used to illustrate variability within the species. The research found no geographical correlation locally or worldwide, and no correlation between molecular, morphological, anatomical, and chemical characters.

Summary: Identifying jellyfish species can be challenging, but a combination of DNA barcoding and morphological characters can aid in the process. In this study, a jellyfish collected from the Mumbai coast was identified as belonging to the genus Rhopilema through morphological and molecular analysis. The analysis of the nuclear Internal Transcribed Spacer 1 gene showed a 99% similarity to Rhopilema hispidum, confirming the species identity.

Summary: Solanum genus is economically important and consists of 1245 accepted species and several major crops. This study provides an overview of the evolution of key morphological traits in Solanum using a recently published phylogeny. The results show that traits related to plant structure, herbivore defence, pollination, and dispersal are highly variable in the genus. The study also reveals convergent traits and unexpected pathways of trait evolution in Solanum.

Summary: The microbial diversity in serofluid dish is mainly influenced by pH, with lactobacillus and related genera, pediococcus, and acetobacter being driven by the variability of pH. The results indicate that the microbial diversity pattern in serofluid dish can be better understood through the pH conditions.

Summary: This study evaluates the monophyly and internal relationships of ten genera under the subfamily Spintharinae. The results support the monophyly of Spintharinae and identify Stemmops as the sister group to the other genera. The study also describes new species and reassignments of certain species.

Summary: The genus Cenophengus LeConte (1881) consists of 27 species distributed mainly in the Americas. A cladistic analysis based on morphological characters confirmed Cenophengus as a monophyletic group, with species primarily found in the Nearctic and Neotropical regions.

Summary: This study provides the first record of Prosthogonimus cuneatus infection in Indian peafowl. The trematode was identified in the bursa of the peafowl through morphological and molecular methods, and histopathological evaluation revealed the changes in the bursal tissue induced by the parasite. The study confirms Indian peafowl as a natural host of P. cuneatus and provides detailed pathological and molecular analysis of the infection.

Summary: This study evaluates the diversity of Pluteus sect. Pluteus and Volvopluteus in Turkey using morphological features and phylogenetic approaches. Four new species are reported as records for Turkey, and the occurrence of Volvopluteus earlei is reported for the first time in the country. The detailed descriptions, color photographs, and microscopic drawings of the newly recorded species are provided, along with comparisons with morphologically and phylogenetically similar species.

Summary: This study conducted both morphological and molecular characterizations of Paramphistomes to ensure the reliability of DNA information for Calichophoron raja species. Through morphological and molecular analysis, it was found that adult flukes from black wildebeest and waterbuck in South Africa matched the previously described Ca. raja, and a new host record of Co. gnou was reported.
