The Circadian Rhythm and Visual Elements in Scorpions: a Review
Arthropods, 2013, 2(4): 150-158 Article The circadian rhythm and visual elements in scorpions: A review M. R. Warburg Dept. of Biology, Technion-Israel Institute of Technology, Haifa 32000, Israel E-mail: [email protected] Received 12 August 2013; Accepted 15 September 2013; Published online 1 December 2013 Abstract The purpose of this paper is to review the state of research in this field and to outline future ways how to proceed. The term: "Zeitgeber", implies ‘time giver’ meaning: synchronizer when an external entrainment factor synchronizes the endogenous rhythm. Is this ‘time’, the chronological date in the sense that it is related to the time of day as reflected in the natural light-dark cycles? Or does it mean cyclic phases of activity as demonstrated in the laboratory? Moreover, is it totally independent of the animal's physiological condition? This subject was studied largely in buthid species (15) of a total of only 30 scorpion species. Moreover, many (over 25%) of the studies (19) were done on a single buthid species: Androctonus australis. Species diversity was observed only by one author’s work who studied eye structure in seven species. Since he found variability in eye structure it would not be advisable to generalize. The fact that experimenting was carried out irrespective of species diversity, gender, ecological or physiological conditions, and was usually done on animals kept in captivity for some time before the experimenting had started, is a major drawback to this kind of study. The diurnal rhythms is triggered either directly through spontaneous arrhythmic activity in the central nervous system, or by neurosecretory material. -

Box 78, Bamaga, QLD 4876, Australia; [email protected] 3 Department of Entomology, Tree Fruit Research and Extension Center, Washington State University, Wenatchee, WA 98801, USA; [email protected] * Correspondence: [email protected]; Tel.: +61-7-4232-1707 Received: 30 June 2020; Accepted: 28 July 2020; Published: 31 July 2020 Abstract: Despite scorpion stings posing a significant public health issue in particular regions of the world, certain aspects of scorpion venom chemistry remain poorly described. Although there has been extensive research into the identity and activity of scorpion venom peptides, non-peptide small molecules present in the venom have received comparatively little attention. Small molecules can have important functions within venoms; for example, in some spider species the main toxic components of the venom are acylpolyamines. Other molecules can have auxiliary effects that facilitate envenomation, such as purines with hypotensive properties utilised by snakes. In this study, we investigated some non-peptide small molecule constituents of Hormurus waigiensis venom using LC/MS, reversed-phase HPLC, and NMR spectroscopy. We identified adenosine, adenosine monophosphate (AMP), and citric acid within the venom, with low quantities of the amino acids glutamic acid and aspartic acid also being present. -

Sexual Dimorphism in the Asian Giant Forest Scorpion, Heterometrus Laoticus Couzijn, 1981
NU Science Journal 2007; 4(1): 42 - 52 Sexual Dimorphism in the Asian Giant Forest Scorpion, Heterometrus laoticus Couzijn, 1981 Ubolwan Booncham1*, Duangkhae Sitthicharoenchai2, Art-ong Pradatsundarasar2, Surisak Prasarnpun1 and Kumthorn Thirakhupt2 1Department of Biology, Faculty of Science, Naresuan University, Phitsanulok 65000 Thailand 2Department of Biology, Faculty of Science, Chulalongkorn University, Bangkok 10400 Thailand *Corresponding author. E-mail address: [email protected] ABSTRACT Morphological characters of adult male and adult female giant forest scorpions, Heterometrus laoticus, in a mixed deciduous forest at Phitsanulok Wildlife Conservation Development and Extension Station showed sexual dimorphism. Among the observed characters, carapace width, chela length, chela width, telson length and shape of movable finger of adult male and female scorpions were obviously different. The pectines of males were also significantly longer, and the number of sensilla-bearing teeth in male scorpions was more than in females. Moreover, males had higher density of sensilla on the pectinal teeth than females. During the breeding season, mature males were mobile while mature females were mainly at their burrows. Keywords: Heterometrus laoticus, sexual dimorphism INTRODUCTION Sexual dimorphism is the difference in form between males and females of the same species. Sexual dimorphism, particularly sexual size dimorphism (SSD) has been observed in a large number of animal taxa (Blanckenhorn, 2005; Brown, 1996; David et al., 2003; Esperk and Tammaru, 2006; Herrel et al. 1999; Ozkan et al., 2006; Ranta et al. 1994; Shine, 1989; Walker and Rypstra, 2001 and Wangkulangkul, et al., 2005). Under the influence of natural and sexual selections, males and females often differ in costs and benefits of achieving some particular body sizes (Crowley, 2000; Gaffin and Broenell, 2001; Kladt, 2003; Mattoni, 2005). -

Ask-a-Biologist Transcript – Vol 018 – (Guests: Conrad Storad, Michael Quinlan) Ask-a-Biologist Vol 018 (Guests: Conrad Storad, Michael Quinlan) Stinging Mystery - It's a mystery, at least until you try to guess what animal children book author Conrad Storad is describing at the beginning of this episode. Joining Conrad is physiologist Michael Quinlan. Together they give us all the gory details behind this desert dwelling animal. Transcript Dr. Biology: This is Ask-a-Biologist, a program about the living world, and I'm Dr. Biology. We have a special show today on an animal that will remain nameless until one of our two guests reads from a book he has written about the animal. In the studio, we have Conrad Storad, who's the editor of ASU Research Magazine and a great children's magazine called "Chain Reaction." He's also a well-known children's book author. Our other guest is researcher, Michael Quinlan, who's an adjunct professor in the School of Life Sciences, and also a professor of Physiology at Midwestern University in Glendale, Arizona. Thank you both for joining me today. Conrad Storad: Thank you, Dr. Biology. Michael Quinlan: Well, thanks for having us. Dr. Biology: To begin, I thought it'd be fun to have Conrad read from one of his books where he writes about the animal that's a mystery at the moment, and what I want everyone to do is to try and guess what animal he has written about. Now, we've modified this a little bit because otherwise, we would give away what the animal is. -
