Exploring species diversity and abundance of scorpions (Arachnida: Scorpiones) in certain regions of Khyber Pakhtunkhwa, Pakistan

open access: yesBrazilian Journal of Biology, 2022
Despite scorpion diversity has long been acknowledged, the mystery of how it develops remains unresolved. The geographical distribution, species abundance and biodiversity of scorpions fauna in Khyber Pakhtunkhwa is poorly explored with many aspects like

Bacterial Adaptation to Venom in Snakes and Arachnida

open access: yesMicrobiology spectrum, 2022
Notwithstanding their 3 to 5% mortality, the 2.7 million envenomation-related injuries occurring annually—predominantly across Africa, Asia, and Latin America—are also major causes of morbidity.

On the life expectancy of a male Chilean rose tarantula, Grammostola rosea (Walckenaer, 1837) (Araneae: Theraphosidae) reared in captivity

open access: yesRevista Chilena de Entomología, 2022
Here we present the case of a male Chilean rose tarantula Grammostola rosea (Walckenaer,1837) (Araneae: Theraphosidae) reared in captivity, whose life expectancy has been dated at 8.5 years. The specimen spent the last three as an adult. Both records are

A Bio-Inspired Method for Mathematical Optimization Inspired by Arachnida Salticidade

open access: yesMathematics, 2021
This paper proposes a new meta-heuristic called Jumping Spider Optimization Algorithm (JSOA), inspired by Arachnida Salticidae hunting habits. The proposed algorithm mimics the behavior of spiders in nature and mathematically models its hunting ...

Comprehensive Species Sampling and Sophisticated Algorithmic Approaches Refute the Monophyly of Arachnida

open access: yesbioRxiv, 2021
Deciphering the evolutionary relationships of Chelicerata (arachnids, horseshoe crabs, and allied taxa) has proven notoriously difficult, due to their ancient rapid radiation and the incidence of elevated evolutionary rates in several lineages.
