Summary: Cyperaceae, the third largest monocot family, is of significant economic and ecological importance and serves as an ideal model for studying evolutionary biology. This study presents the first family-wide phylogenomic study of Cyperaceae based on targeted sequencing, providing a new classification at the tribal, subtribal, and generic levels. The research also establishes support for tribe Cryptangieae as a clade including the genus Koyamaea, and introduces five new subtribes in tribe Schoeneae.

Summary: The study explored the phylogenetic relationships within the Polypodiaceae family using plastid and nuclear genome data, revealing incongruences between some clades and along the backbone of the phylogeny. This discrepancy may be attributed to complex evolutionary histories within these clades, such as rapid radiation, incomplete lineage sorting, ancient hybridization, and recent introgression. Despite these challenges, the study identified nine major clades in Polypodiaceae that can be recognized as subfamilies, with support from both molecular and non-molecular features.

Summary: This study refines species limits in the Western Australian endemic genus Anarthria and identifies three distinct species within material historically classified as Anarthria gracilis R.Br. The use of nuclear DNA markers allowed for the recognition of a group comprising all three ligulate species of Anarthria. The discovery of previously unrecognized species underscores the need for further taxonomic research in this group of wind-pollinated plants.

Summary: The diaspores morphology of Anarthriaceae and Australian Restionaceae were studied using microscopy and the results were compared with a previously published phylogeny based on plastid genes. It was found that the fruit type of Restionaceae has evolved multiple times and the surface patterns of the seeds and the characteristics of the pericarps play an important role in classification. The weight and type of the seeds vary in different habitats. However, the association between seed type and habitat has not been extensively studied.

Summary: This study investigates the developmental morphology and anatomy of Rapateaceae, a plant family with unique inflorescence and gynoecium structures. The research found that this family lacks septal nectaries, but a bird-pollinated tribe within the family possesses a unique non-septal nectary.

Summary: This study describes two new species of Cryptanthus from Bahia State, Brazil, with one occurring in Atlantic Forest and the other in a transition area between Atlantic Forest and Caatinga. The two new species are differentiated by stem diameter, leaf sheath width, sepal and petal color, anther apex shape, ovary length and width, as well as other floral characteristics. Comparisons are made with morphologically similar species in terms of geographic distribution, habitat, conservation status, and taxonomy.

Summary: This study investigated the nutritional status of tribal and non-tribal adult people living in the rural area of Rajshahi district, Bangladesh. The results showed that the prevalence of under-nutrition was higher among tribal men and women compared to non-tribal individuals. The study also identified certain socio-economic and demographic factors as predictors of malnutrition.

Summary: This study uses molecular phylogenetic analysis of four gene fragments to assess the generic relationships within the parasitoid wasp subfamily Braconinae. The results support the recognition of existing tribes and the addition of three new tribes. The placement of Amyosoma Viereck within one of the new tribes is discussed, while a preliminary key to tribes and revised differentiation characters are presented.

Summary: Dipterocarpoideae, the largest subfamily in the Meranti family, are dominant trees in wet tropical Asia facing increasing anthropogenic pressures. They have been the focus of numerous studies due to their economic value, historical biogeographical importance, and role in the evolution of the Asian tropical forest biome. Despite persistent taxonomic and evolutionary questions, a comprehensive phylogenomic hypothesis has been proposed, revising the tribal classification of the subfamily into four main clades based on plastome and nuclear cistron data.

Summary: The study examines the heterogeneity of smallholder farms in Jharkhand, India, and proposes a methodology to classify farms based on their characteristics. By analyzing various variables, the study identifies four farm types and validates the clusters through qualitative methods. The findings suggest that categorizing farmers based on their characteristics can facilitate the targeted implementation of agricultural technologies and interventions.

Summary: This study investigated the presence and diversity of the ligule and contraligule in Cyperaceae, revealing that there are genera with ligules and a rare ligule-like structure called contraligule. These structures are absent in most species but play important roles in classification.
