Description of Bothriurus mistral n. sp., the highest-dwelling Bothriurus from the western Andes (Scorpiones, Bothriuridae), using multiple morphometric approaches. [PDF]
PLoS ONE, 2023 We describe Bothriurus mistral n. sp. (Scorpiones, Bothriuridae) from the Chilean north-central Andes of the Coquimbo Region. This is the highest elevational discovery for Bothriurus in the western slopes of the Andes.

Morphometric study and sexual dimorphism analyses in an Iranian population of Scorpio maurus (Arachnida: Scorpionidae). [PDF]
Ecol Evol, 2021 Scorpio maurus was collected and evaluated for morphometric study and sexual dimorphism analyses for the first time in Iran. 53 morphological characters of 15 specimens of each sex of S. maurus were studied. Sexual dimorphism was observed in 21 morphological characters of S. maurus based on statistical analyses.

End of the Season Blues: Senescence and Reproductive Trade-Offs in Male Scorpions [PDF]
InsectsSeasonal reproductive dynamics and senescence have profound impacts on male fertility, yet these processes remain understudied in scorpions. This study investigates how reproductive parameters—such as testicular mass, sperm quantity, and viability—change

Free Pasture of Exotic Goats Reduces Diversity and Negatively Affects Body Condition in Scorpions (Arachnida: Scorpiones) Assemblage From Brazilian Seasonal Dry Tropical Forest. [PDF]
Ecol EvolFree goat grazing impacts the Caatinga vegetation. Negatively affecting the scorpion assemblage. Furthermore, it presents context‐dependent effects on the body traits of these arachnids. ABSTRACT Extensive grazing carried out freely by exotic goats represents an important source of anthropogenic degradation in seasonally dry tropical forests of Brazil.

Comparative cytogenetics among populations of two Bothriurus species (Scorpiones, Bothriuridae) [PDF]
Comparative CytogeneticsBothriurus Peters, 1861 is one of the most diverse genera within the family Bothriuridae. However, to date, only five species have been analyzed using a cytogenetic approach.

The role of bromeliad structural complexity on the presence, spatial distribution and predator avoidance in <i>Tityus neglectus</i> (Scorpiones: Buthidae). [PDF]
Ecol EvolDue to remarkable architectural design featuring rosette‐like leaf arrangements, bromeliads serve as habitats for various species. Bromeliad architecture is a key factor in the spatial distribution and occurrence of the Tityus neglectus scorpion. Furthermore, T.

The male sexual apparatus in the order Scorpiones (Arachnida): a comparative study of functional morphology as a tool to define hypotheses of homology [PDF]
Frontiers in Zoology, 2017 Background Insemination in scorpions is carried out by means of a partly sclerotized structure, the spermatophore, which is composed of two separate halves, the hemispermatophores. In most genera these reproductive structures can be used to differentiate

Testes mass, but not sperm length, increases with higher levels of polyandry in an ancient sex model. [PDF]
PLoS ONE, 2014 There is strong evidence that polyandrous taxa have evolved relatively larger testes than monogamous relatives. Sperm size may either increase or decrease across species with the risk or intensity of sperm competition.

Untangling the web: dynamics of Australia's online terrestrial invertebrate trade
Austral Entomology, Volume 62, Issue 3, Page 372-387, August 2023., 2023 Abstract The trade and keeping of exotic pets has serious implications for both biosecurity and biodiversity conservation. In Australia, the online trade of live invertebrates is an understudied and unregulated issue, with almost non‐existent monitoring. It is uncertain what species are being traded, whether they are being identified correctly, and how

Biological Reviews, Volume 98, Issue 3, Page 942-981, June 2023., 2023 ABSTRACT Acoustic and substrate‐borne vibrations are among the most widely used signalling modalities in animals. Arthropods display a staggering diversity of vibroacoustic organs generating acoustic sound and/or substrate‐borne vibrations, and are fundamental to our broader understanding of the evolution of animal signalling.
