Distribution and species diversity of freshwater crabs of the family Pseudothelphusidae in Colombia (Crustacea: Decapoda: Brachyura)

open access: yesNauplius, 2020
The study of Colombian freshwater crabs has advanced significantly, but species records are scattered across different museums and research institutions. Assuming that museum collections incorporate valuable information in estimating species diversity, a

Endemic Species Of Flora Kuhitang Ridge

open access: yesThe American Journal of Agriculture and Biomedical Engineering, 2020
The article says that of the 25 endemic species of the Kugitang flora, 18 species are found in the eastern part of the ridge, i.e. within Uzbekistan. All endemic to the Uzbek part are protected by the Surkhan reserve. This indicator indicates the great importance of the Surkhan reserve in the gene pool of the Kugitang plant diversity.

Enhanced Sensitivity of a Modified Quaking‐Induced Conversion Diagnostic Test for the Broad Detection of Sporadic and Inherited Prion Diseases: A Retrospective Study

open access: yesAnnals of Neurology, EarlyView.
Objective Quaking‐induced conversion (QuIC) tests, which detect prion‐seeding activity in cerebrospinal fluid (CSF), have markedly advanced the antemortem diagnosis of prion diseases such as Creutzfeldt‐Jakob disease (CJD). These tests provide high diagnostic accuracy and enable timely differentiation from other rapidly progressive neurodegenerative ...

Reinstatement of the Chinese endemic species Styrax zhejiangensis [PDF]

open access: yesPhytoKeys, 2019
Styrax zhejiangensis has been treated as a synonym of S. macrocarpus. Examination of herbarium specimens and observation of wild living plants demonstrates that S. zhejiangensis is a distinct species and is clearly distinguishable from S. macrocarpus through its flowering phenology in which leaves and flowers open simultaneously, its smaller corolla ...

A Multiepitope‐Based Lateral Flow Assay for Leprosy Antibodies

open access: yesAnalysis &Sensing, EarlyView.
An innovative lateral flow assay for leprosy diagnosis is based on gold nanoparticles and synthetic Mycobacterium leprae epitopes conjugated to keyhole limpet hemocyanin protein to enhance antibody detection. This strategy provides a rapid, accurate, and low‐cost approach for resource‐limited settings, enabling the early detection of infection. Leprosy

Variation in parrot jaw musculature

open access: yesThe Anatomical Record, EarlyView.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

Invasibility and species richness of island endemic arthropods: a general model of endemic vs. exotic species [PDF]

open access: yesJournal of Biogeography, 2005
AbstractAim This paper has two objectives. First, we examine how a variety of biotic, abiotic and anthropogenic factors influence the endemic and introduced arthropod richness on an oceanic island. Second, we look at the relationship between the endemic and introduced arthropod richness, to ask whether areas with high levels of endemic species richness
