Iurus populations from the Aegean area are studied, including the Greek islands of Crete, Karpathos, Kythira, Rhodes, and Samos. A new genus, Protoiurus gen. nov., and two new species, Protoiurus rhodiensis sp. nov. and P. stathiae sp. nov., are described. The two genera, Iurus and Protoiurus, are diagnosed by their hemispermatophore structure; a cladistic analysis based on this structure is presented. Genus Iurus Thorell, 1876 includes three species: I. dekanum, I. dufoureius, and I. kinzelbachi; genus Protoiurus includes five species: P. asiaticus comb. nov., P. kadleci comb. nov., P. kraepelini comb. nov., P. rhodiensis sp. nov., and P. stathiae sp. …
Evolution Of Scorpion Orthobothriotaxy: A Cladistic Approach, Michael E. Soleglad, Victor Fet
Evolution Of Scorpion Orthobothriotaxy: A Cladistic Approach, Michael E. Soleglad, Victor Fet
Victor Fet
This study presents a cladistic analysis of the derivation of orthobothriotaxic patterns in scorpions. Included in this analysis are the original three orthobothriotaxic patterns defined by Vachon (1972, 1974), the pattern of the unique scorpion Pseudochactas ovchinnikovi Gromov, 1998, and two trichobothrial patterns of fossil scorpions, the Upper Carboniferous palaeopisthacanthids and the Lower Cretaceous archaeobuthids. An overview of all fossil scorpion material where trichobothria are reported is presented in detail. The approach used in this analysis is to model the existence of an individual trichobothrium, adopting the ‘absence of’, ‘petite size’ and ‘full size’ as incremental stages of a trichobothrium’s …
Morphology Analysis Supports Presence Of More Than One Species In The “Euscorpius Carpathicus” Complex (Scorpiones: Euscorpiidae), Victor Fet, Michael E. Soleglad
Morphology Analysis Supports Presence Of More Than One Species In The “Euscorpius Carpathicus” Complex (Scorpiones: Euscorpiidae), Victor Fet, Michael E. Soleglad
Victor Fet
We investigate a number of scorpion populations from southern and central Europe, commonly classified under a “catch-all” name of Euscorpius carpathicus (L., 1767). This species includes a high number of described subspecies but its composition is not resolved. The detailed morphology analysis in the present paper includes a number of new characters, in particular individually mapped external patellar accessory trichobothria. It suggests that several clearly separated lineages are present. E. carpathicus (L.) is restricted here to geographically marginal populations from Romania (terra typica), which exhibit loss of one trichobothrium in the patellar series em (= 3). Another lineage (Austria, Croatia, …
Etudes On Iurids, Ii. Revision Of Genus Calchas Birula, 1899, With The Description Of Two New Species (Scorpiones: Iuridae), Victor Fet, Michael E. Soleglad, František Kovařík
Etudes On Iurids, Ii. Revision Of Genus Calchas Birula, 1899, With The Description Of Two New Species (Scorpiones: Iuridae), Victor Fet, Michael E. Soleglad, František Kovařík
Victor Fet
The relict, phylogenetically important scorpion genus Calchas Birula, 1899 (Iuridae) remained monotypic since its description. Its sole species, Calchas nordmanni Birula, 1899, was known only from northeastern Turkey until Kinzelbach (1980) published first records from southern and southeastern Turkey. A few more localities have been reported from Turkey; the species was also found on two Greek islands, Samos and Megisti. We analyzed significant material (63 specimens, including a previously unpublished large series from Naturhistorisches Museum Wien), and concluded that three distinct, disjunct species exist rather than one widespread species as previously thought. Two new species are described: Calchas birulai sp. …

A new species of Hottentotta Birula, 1908 is described from the Kabul area in Afghanistan; this addition represents the fifth species of this genus confirmed for this Middle East country. It is a member of the “Indian group” of the genus (the first one recorded from Afghanistan), and is most closely related to Hottentotta jabalpurensis Kovařík, 2007, Hottentotta stockwelli Kovařík, 2007, Hottentotta tamulus (Fabricius, 1798) and Hottentotta songi (Lourenço, Qi et Zhu, 2005) n. comb., which is herein demonstrated to be a member of Hottentotta and is thus formally transferred to this genus.

Several new Calchas populations are studied from Turkey, including specimens from Hakkari Province, which borders the northern edge of Iraq. A new genus, Neocalchas, gen. nov., and two new species, Calchas anlasi, sp. nov. and C. kosswigi, sp. nov., are described. The two genera, Calchas and Neocalchas, are diagnosed by their hemispermatophore structure, chelal finger dentition, telson morphometrics and setation, and trichobothrial topology of the pedipalp chela. Genus Calchas Birula, 1899 includes four species: C. anlasi, sp. nov., C. birulai, C. kosswigi, sp. nov., and C. nordmanni; genus Neocalchas, gen. nov., includes one species, N. gruberi, comb. nov. New diagnoses …

Contributions To Scorpion Systematics. I. On Recent Changes In High-Level Taxonomy, Victor Fet, Michael E. Soleglad
Victor Fet
Prendini & Wheeler (2005) criticized the methods of phylogenetic analyses by Soleglad, Fet, and their coauthors, and executed an unprecedented taxonomic action: without analyzing any of these taxa, they performed a wholesale synonymization of four parvorders, eight superfamilies, one family, 11 subfamilies, eight tribes, two subtribes, and three genera (in total, 37 taxa) of scorpions, and made other taxonomic changes. No alternative new classification has been proposed (instead, they revert to a previous classification), and no results of original work on this subject by Prendini & Wheeler (2005) have been presented. Here, we reverse all taxonomic changes performed by Prendini …
Determining Winter Flounder Spawning Sites In Two Connecticut Estuaries, Eric Schultz, Jose Pereira, Peter Auster
Determining Winter Flounder Spawning Sites In Two Connecticut Estuaries, Eric Schultz, Jose Pereira, Peter Auster
Jose J Pereira
Winter flounder (Pseudopleuronectes americanus) come inshore during the late winter and early spring to lay their eggs in shallow bays and estuaries along the coast. Unlike most fish eggs, which are buoyant, these eggs are demersal and sink to the seafloor. This makes them vulnerable to burial from various types of natural and human caused disturbances (e.g., storms, mobile fishing gear, maintenance dredging). Our objective was to map spawning areas in two harbors and search for generalities among these sites that would allow us to predict where winter flounder might spawn in other areas. This would allow managers to avoid …
Population Dynamics Of Spiders In Ayya Nadar Janaki Ammal College Campus, Sivakasi, Virudhunagar District, Tamil Nadu, India, Jeyaparvathi S
Population Dynamics Of Spiders In Ayya Nadar Janaki Ammal College Campus, Sivakasi, Virudhunagar District, Tamil Nadu, India, Jeyaparvathi S
JOZS JOURNAL
Spiders play an important role in regulating insect pests in the agricultural ecosystem. There are a large number of species, many of them with high population densities. A survey was conducted in the Ayya Nadar Janaki Ammal College campus from January, 2011 - March, 2011. 29 individuals were collected representing 11 families and 21 genera. From these, 25 species were present throughout the campus; however, only 5 of these were taken in the ground, they are the ground dwellers. Peucetia viridana (Stolizcka), Oxyopes hindostanicus (Tikader), Lycosa pseudoannulata (Bosenberg) and Plexippus petersi, were common. P. viridana was the dominant species followed …

Species Distribution Modelling Using Bioclimatic Variables To Determine The Impacts Of A Changing Climate On The Western Ringtail Possum (Pseudocheirus Occidentals; Pseudocheiridae), Shaun Molloy, Robert Davis, Eddie Van Etten
Shaun W Molloy Dr
The ngwayir (western ringtail possum Pseudocheirus occidentalis) is an arboreal species endemic to south-western Australia. The range and population of this species have been significantly reduced through multiple anthropogenic impacts. Classified as vulnerable, the ngwayir is highly susceptible to extremes of temperature and reduced water intake. Ngwayir distribution was determined using three different species distribution models using ngwayir presence records related to a set of 19 bioclimatic variables derived fromhistorical climate data, overlaid with 2050 climate change scenarios.MaxEnt was used to identify core habitat and demonstrate how this habitat may be impacted. A supplementary modelling exercise was also conducted to …
Can They Dig It? Functional Morphology And Degrees Of Semifossoriality Among Some American Shrews (Mammalia, Soricidae)., Neal Woodman, Sarah A. Gaffney
Can They Dig It? Functional Morphology And Degrees Of Semifossoriality Among Some American Shrews (Mammalia, Soricidae)., Neal Woodman, Sarah A. Gaffney
Neal Woodman
Small-eared shrews (Mammalia: Soricidae: Cryptotis), exhibit modifications of the forelimb skeleton that have been interpreted as adaptations for semifossoriality. Most species inhabit remote regions, however, and their locomotory and foraging behaviors remain mostly speculative. To better understand the morphological modifications in the absence of direct observations, we quantified variation in these species by measuring 151 individuals representing 18 species and populations of Cryptotis and two species of moles (Talpidae) for comparison. From our measurements, we calculated 22 indices, most of which have been used previously to characterize substrate use among rodents and other taxa. We analyzed the indices using 1) …
