Gene and Genome Duplication in Spiders

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In chelicerates whole genome duplications (WGDs) were identified in distinct groups. While there is evidence that Xiphosurans/horseshoe crabs had three rounds of WGD and arachnopulmonates (e.g. spiders and scorpions) had one WGD, in many other arachnid groups no WGD was identified.

Target-Specificity in Scorpions; Comparing Lethality of Scorpion Venoms across Arthropods and Vertebrates

Toxins, 2017
Scorpions use their venom in defensive situations as well as for subduing prey. Since some species of scorpion use their venom more in defensive situations than others, this may have led to selection for differences in effectiveness in defensive ...

Surgery in Ovarian Cancer—Brazilian Society of Surgical Oncology Consensus

Journal of Surgical Oncology, EarlyView.
ABSTRACT Surgical management in epithelial ovarian cancer (EOC) has a significant impact on overall survival (OS) and progression‐free survival (PFS). The Brazilian Society of Surgical Oncology (BSSO) supported an expert‐led task force for consensus: the best EOC surgery is provided by experienced and specialized trained surgeons in cancer centers ...

Redescription of Euscorpius studentium Based on Adult Specimens; Updated Classification of Cavernicolous Euscorpiidae; and Review of Cavernicolous Scorpions in the Balkans

Diversity
Cavernicolous scorpions are difficult to collect and study due to their often inaccessible habitats. Some have evolved unique morphological adaptations, known as troglomorphies, including reduced sclerotization and pigmentation, reduction and/or loss of ...

Serrulin: A Glycine-Rich Bioactive Peptide from the Hemolymph of the Yellow Tityus serrulatus Scorpion

Toxins, 2019
Antimicrobial peptides (AMPs) are small molecules, which have a potential use as antibiotic or pharmacological tools. In chelicerate organisms, such as scorpions, these molecules constitute an alternative defense system against microorganisms. The aim of

Metabarcoding analysis of different portions of the digestive tract of scorpions (Scorpiones, Arachnida) following a controlled diet regime shows long prey DNA half‐life

Environmental DNA, 2022
Molecular analysis of gut content is one of the widest used methods to investigate diet in arthropods. Stomach content analysis in some arthropods is particularly difficult, e.g., in arachnids, because they have external digestion and a low foraging ...

Suicide of Scorpions [PDF]

Nature, 1883
SPEAEKING of scorpion suicide, Mr. G. J. Romanes in his “Animal Intelligence writes:” Still I think that so remarkable a fact unquestionably demands further corroboration before we shall be justified in accepting it unreservedly” (p. 225). Some years ago I made some experiments and observations on a smaller and a larger species of scorpion found on the
