Download The Biology of Camel-Spiders: Arachnida, Solifugae by Fred Punzo PDF

By Fred Punzo

My preliminary curiosity within the Solifugae (camel-spiders) stems from an incident that happened in the summertime of 1986. i used to be learning the behavioral ecology of spider wasps of the genus Pepsis and their interactions with their huge theraphosid (tarantula) spider hosts, within the Chihuahuan wilderness close to substantial Bend nationwide Park, Texas. i used to be tracking a selected tarantula burrow one evening whilst i realized the resident woman move slowly up into the burrow front. Hoping to take a few images of prey catch, I put a cricket close to the doorway and waited for the spider to pounce. without warning, out of the comer of my eye seemed a wide, swiftly relocating yellowish shape which siezed the cricket and speedy ran off with it till it disappeared underneath a close-by mesquite bush. So without notice and speedy had the series of occasions happened, that i discovered myself momentarily startled. as a result of a headlamp I quickly positioned the intruder, a solifuge, who was once already busy at paintings macerating the insect with its huge chelicerae (jaws). while i tried to nudge it with the sting of my forceps, it quick moved to a different situation underneath the bush. whilst I repeated this maneuver, the solifuge dropped the cricket and lunged on the forceps, gripping them tightly in its jaws, refusing to liberate them till they have been forcefully pulled away.

A Textbook of Agricultural Entomology

A whole realizing of the biology and lifestyles histories of pest species is essential for all these concerned with crop construction and crop safety. this crucial new identify presents complete assurance of significant insect and mite pest species, essentially in Northern Europe. Textbook of Agricultural Entomology is extensively divided into elements.

Insect Conservation: A Handbook of Approaches and Methods (Techniques in Ecology and Conservation)

With as much as 1 / 4 of all insect species heading in the direction of extinction over the following few a long time, there's now a urgent have to summarize the strategies to be had for measuring insect variety so as to advance powerful conservation techniques. Insect Conservation outlines the most equipment and methods on hand to entomologists, delivering a entire synthesis to be used through graduate scholars, researchers and working towards conservationists around the world.

A Survey of the Lepidoptera, Biogeograhy and Ecology of New Caledonia

I spent 4 months in New Caledonia in 1971 with the item of constructing a quantitative survey of the night-flying macrolepidoptera with light-traps and an evaluate of the Rhopalocera and microlepidoptera. This fieldwork was once financed by way of a central authority Grant-in-Aid for clinical Investigations adminis­ tered by means of the Royal Society, and by way of a supply from the Godman Fund.

In Galeodes , this rather small ganglion gives rise to five pairs of nerves that innervate the posterior six abdominal segments (Bernard, 1896; Babu, 1985). With respect to the solifuge stomatogastric nervous system (SNS), studies have indicated that its degree of development can vary considerably. Morphological analyses conducted by Junqua (1966) on Othoes saharae, showed that the paired SNS was absent in this species. However, in Eremobates purpusi (Henry, 1954), an unpaired SNS is formed by a rostral nerve (nerve of segment 1, labrum) and a recurrent nerve (Figure 3-4).

Some of the neurosecretory cells associated with the SNS (Figure 3-5) are active during the intermolt cycle in O.

This suggests that solifuges may exhibit more advanced gas exchange capabilities than other arachnids. It is well known that solifuges are typically fossorial and spend a great deal of time in burrows and other refugia that are frequently characterized by hypoxic or hypercapnic conditions (Schmidt-Nielsen, 1964; Edney, 1977; Heatwole, 1995). In such environments, discontinuous gas exchange would represent a reasonable respiratory strategy. Lighton and Fielden (1996) conducted a detailed study on the gas exchange dynamics of two eremobatid solifuges from the Mojave Desert in California.
