Abstract:

Some octocorals (Cnidaria, Anthozoa) can produce a sub-millimeter to a millimeter-range skeleton of calcium carbonate, known as sclerites. Sclerites have diverse morphological characters, such as size, and shape features that give them relevance as taxonomic characters at different levels. Renilla Lamarck, 1816, is a genus of the order Pennatulacea (Octocorallia), in which colonies are characterized by two distinct zones: a peduncle, which anchors them to the substrate, and a rachis that supports the polyps. In the case of Renilla muelleri Kölliker, 1872, prior research established the presenc

Abstract:

Biblidinae is a subfamily of Nymphalidae with over 250 species for the Neotropical Region. All males have a modified eighth sternum, this being the hypandrium. In order to demonstrate the structural variability and to assist in species identification, the morphological variations in species of 24 genera are illustrated and analyzed. Methods traditionally applied to dissection in Lepidoptera were used. To illustrate the variations, drawings were done with the aid of a camera lucida attached to a stereomicroscope and Scanning Electron Microscopy. The sclerite showed great variation with special

The occurrence of cryptic species among economically important fruit flies strongly affects the development of management tactics for these pests. Tools for studying cryptic species not only facilitate evolutionary and systematic studies, but they also provide support for fruit fly management and quarantine activities. Previous studies have shown that the South American fruit fly, Anastrepha fraterculus, is a complex of cryptic species, but few studies have been performed on the morphology of its immature stages.

In this study, the metabolites released by the pathogenic strains of S. sclerotiorum under the axenic culture have been identified using the untargeted high-resolution UPLC-QTOF-ESI-MS/MS.

Abstract:

Abstract Ocular rosacea is a chronic inflammatory condition associated with cutaneous rosacea, affecting up to 72% of patients with the disease. Its pathophysiology involves genetic predisposition, immune dysfunction, neurovascular alterations, and microbiome dysregulation, leading to chronic ocular surface inflammation and epithelial barrier disruption. Clinically, it manifests as eyelid telangiectasias, blepharitis, meibomian gland dysfunction, and keratitis, with potential progression to scleritis or corneal neovascularization in severe cases. Despite its high prevalence, the variability in

Abstract:

Abstract Background Early Cambrian Lagerstätten from China have greatly enriched our perspective on the early evolution of animals, particularly arthropods. However, recent studies have shown that many of these early fossil arthropods were more derived than previously thought, casting uncertainty on the ancestral euarthropod body plan. In addition, evidence from fossilized neural tissues conflicts with external morphology, in particular regarding the homology of the frontalmost appendage. Results Here we redescribe the multisegmented megacheirans Fortiforceps and Jianfengia and describe Sklero

Abstract:

ABSTRACTIn the present investigation, nutlet morphological and micro‐morphological characters were analyzed using Light Microscope (LM) and Scanning Electron Microscope (SEM) in 38 taxa under 13 genera from the sub‐family Cyperoideae of Cyperaceae to find out whether these characters are taxonomically important or not. Nutlet morphology and surface characters of the representative taxa from all the possible tribes under the sub‐family Cyperoideae namely, Fuireneae, Cypereae, Cariceae, Abildgaardieae, Eleocharideae, Pseudoschoeneae, Schoenoplecteae, and Sclerieae were evaluated for their taxono
