The envenomation of general physiology throughout the last century. [PDF]

open access: yes, 2017
Toxins are the poisonous products of organisms. Toxins serve vital defensive and offensive functions for those that harbor them: stinging scorpions, pesticidal plants, sanguinary snakes, fearless frogs, sliming snails, noxious newts, and smarting spiders.

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

open access: yesThe Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment

open access: yesThe Anatomical Record, EarlyView.
Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

Animal suicide: An account worth giving? Commentary on Peña-Guzmán on Animal Suicide [PDF]

open access: yes, 2018
Peña-Guzmán (2017) argues that empirical evidence and evolutionary theory compel us to treat the phenomenon of suicide as continuous in the animal kingdom.

The Morphology and Histology of New Sex Pheremone Glands in Male Scorpionflies, Panorpa and Brachypanorpa (Mecoptera: Panorpidae and Panorpodidae) [PDF]

open access: yes, 2017
The n~orphology and histology of a previously undescribed sex pheromone gland in male scorpionflies of the genus Panorpa (Mecoptera: Panorpidae) and a morphologically similar gland in Brachypanorpa (Mecoptera: Panorpodidae) are described and discussed ...

Arthroscopic One‐to‐One Anchor, Double‐Row Rotator Cuff Repair

open access: yesArthroscopy Techniques, EarlyView.
Abstract Rotator cuff repair aims to achieve stable tendon‐to‐bone healing while restoring the anatomic footprint and minimizing tension. Although single‐row and double‐row constructs are widely used, double‐row repairs have showed biomechanical advantages, including broader footprint coverage, improved force distribution, and reduced gap formation ...

SCORPIONS, SCORPIONISM, LIFE HISTORY STRATEGIES AND PARTHENOGENESIS

open access: yesJournal of Venomous Animals and Toxins, 1995
Recently public health problems resulting from scorpion stings have shown an alarming increase in various tropical and subtropical countries such as Brazil, Mexico, Tunisia and Morocco. In some regions of Brazil, particularly in the States of Minas Gerais, Sao Paulo, Bahia, Goias and the Federal District, more than 6000 scorpion stings with over 100 ...

Autologous Palmaris Longus Tendon Augmentation for Large to Massive Rotator Cuff Tears

open access: yesArthroscopy Techniques, EarlyView.
Abstract This technical note describes an arthroscopic technique that utilizes the autologous palmaris longus (PL) tendon to augment large to massive rotator cuff tears when complete repair is not feasible. The PL tendon is harvested through a minimal wrist incision and delivered intramuscularly into the supraspinatus and/or infraspinatus using a ...

Phosphorescent Animal Forms of Arkansas [PDF]

open access: yes, 1971
Two phosphorescent animal forms, Euryurus sp. and Centruroides vittatus, were collected with a black light in an attempt to collect phosphorescent spiders. Both the millipede and the scorpion were easily observed by the bright phosphorescent yellow color

A neuro‐behavioural model of neophobia

open access: yesBiological Reviews, EarlyView.
ABSTRACT Fear can be defined as the internal neurological state that releases a repertoire of behaviours an animal performs to reduce the effect of an aversive factor. Neophobia, the fear of novelty, is a fundamental behavioural trait observed across a wide range of species from arthropods to humans.
