AI Article Synopsis
- Eastern Brazil's mountainous regions host a rich diversity of Phytoseius species, with 11 discovered during surveys from 2010 to 2012.
- The study identifies seven new species within the plumifer species-group and emphasizes the importance of specific morphological traits for accurate taxonomic classification.
- The research proposes renaming the plumifer group to the mexicanus-species group due to discrepancies in classification and includes a key for identifying Brazilian Phytoseius species.
Article Abstract
The mountainous regions in eastern Brazil are home to an astonishing variety of Phytoseius (Mesostigmata: Phytoseiidae) species, 11 of which were collected in surveys conducted between 2010-2012. Our study revealed a great diversity in the plumifer species-group, in which we describe seven new taxa, P. maspretiosus sp. nov., P. multilunatus sp. nov., P. trisetatus sp. nov., P. itobira sp. nov., P. dasalmas sp. nov., P. bahiensis sp. nov., and P. paucipapillatus sp. nov.. This enabled us to compare close species in this group determining valid diagnostic characters, providing a critical review of the prevailing taxonomic traits and revealing unexpected patterns in important diagnostic features based on our observations and the literature. Moreover, we claim the taxonomic importance of two morphological traits usually mentioned in previous studies, but never exploited to their full potential: the female pattern of dorsal ornamentation and the shape of the male spermatodactyl. Aware of the incongruity that the exemplar species of the plumifer group, P. plumifer (Canestrini & Fanzago), belongs to the horridus species group, we propose that the group be renamed as mexicanus-species group. A key to the Brazilian species of Phytoseius is included.

The tick fauna of El Salvador is currently represented by 10 species of hard ticks (family Ixodidae) and 2 species of soft ticks (family Argasidae). This study aimed to report new and additional records of ticks and rickettsiae in El Salvador. During 2019-2021, a total of 216 specimens of ticks were collected from eight host species (domestic and wild animals) and in the environment among 15 geographic localities of El Salvador.

The clustered distribution of genes involved in metabolic pathways within the plant genome has garnered significant attention from researchers. By comparing and analyzing changes in the flanking regions of metabolic genes across a diverse array of species, we can enhance our understanding of the formation and distribution of biosynthetic gene clusters (BGCs). In this study, we have designed a workflow that uncovers and assesses conserved positional relationships between genes in various species by using synteny neighborhood networks (SNN).

The Rhipicephalus sanguineus group is an assembly of species morphologically and phylogenetically related to Rhipicephalus sanguineus sensu stricto. The taxonomy and systematics of this species group have remained obscure for a long time, but extensive research conducted during the past two decades has closed many knowledge gaps. These research advancements culminated in the redescription of R.

Background: Fruits, with their diverse shapes, colors, and flavors, represent a fascinating aspect of plant evolution and have played a significant role in human history and nutrition. Understanding the origins and evolutionary pathways of fruits offers valuable insights into plant diversity, ecological relationships, and the development of agricultural systems. Arabidopsis thaliana (Brassicaceae, core eudicot) and Eschscholzia californica (California poppy, Papaveraceae, sister group to core eudicots) both develop dry dehiscent fruits, with two valves separating explosively from the replum-like region upon maturation.

Objective: He Shi Yu Lin Formula (HSYLF) is a clinically proven prescription for treating premature ovarian insufficiency (POI), and has shown a good curative effect. However, its molecular mechanisms are unclear. This study aimed to investigate the molecular mechanisms of HSYLF and clarify how network pharmacology analysis guides the design of animal experiments, including the selection of effective treatment doses and key targets, to ensure the relevance of the experimental results.
