The system, developed in massive Mesozoic limestone, has two distinct resur- gences. Despite relatively limited sampling, its subterranean fauna is rich, composed of a number of local endemics, terrestrial as well as aquatic, including two remarkable relictual species, Arbasus cae- cus (Simon, 1911) and Tritomurus falcifer Cassagnau, 1958. With 38 stygobiotic and troglobiotic species recorded so far, the Coume Ouarnède system is the second richest subterranean hotspot in France and the first one in Pyrenees. This species richness is, however, expected to increase because several taxonomic groups, like Ostracoda, as well as important subterranean habitats, like MSS (“Milieu Souterrain Superficiel”), have not been considered so far in inventories. Similar levels of subterranean biodiversity are expected to occur in less-sampled karsts of central and western Pyrenees.

  • A New Cavernicolous Species of the Pseudoscorpion Genus Roncus L
    Int. J. Speleol. 5 (1973), pp. 127-134. A New Cavernicolous Species of the Pseudoscorpion Genus Roncus L. Koch, 1873 (Neobisiidae, Pseudoscorpiones) from the Balkan Peninsula by Bozidar P.M. CURtlC * The range of the pseudoscorpion subgenus Parablothrlls Beier 1928 (from the genus Roncus L. Koch 1873) extends over the northern Mediterranean, covering a vast zone from Catalonia on the west as far as Thrace on the east. The northern limit of distribution of these false scorpions is situated within the Dolomites and the Alps of Carinthia; the most southern locations of the subgenus were registered on the island of Crete. Eight species of Parablothrus are known to inhabit the Balkan Peninsula which represents an impo;:tant distribution centre of the subgenus (Beier 1963, Helversen 1969); of them, six were found in the Dinaric Karst. The caves of Carniola are thus populated by R. (F:) stussineri (Simon) 1881, and R. (P) anophthalmus (Ellingsen) 1910, R. (P.) cavernicola Beier 1928 and R. (P) vulcanius Beier 1939 are known from Herzegovina. The last species was also collected on some Dalmatian islands. Both Adriatic and Ionian islands are inhabited by two other members of Parablo- thrus, namely R. (P.) insularis Beier 1939 (which was found on the isle of Brae) and R. (P) corcyraeus Beier 1963, the latter living on Corfu. Except for the Dinaric elements of Parablothrus, the Balkan representatives of the subgenus have not been sufficiently studied. In spite of this, one may assume that the differentiation of cave living species of Roncus took place both east and north of the peninsula.

Apnroximately 1450 specimens were collected by the author. Around 500 additional snecimens were made available for this survey from institutional and nersonal collections. Records published prior to this study list four species of pseudoscorpions in the state. With the nresent survey the list has been increased to include twelve species, ten genera, five families, and three suborders. Three of the four previously recorded species were taken at new locali- ties. An accurate species determination could not be made for six specimens. They appear to demonstrate the presence of three or four additional genera and species. Pseudoscorpions have varied habitat preferences. Four species were found in the leaf litter and ground cover of deciduous forests: ghfhonius tetraghelgtus, pactvlocheljfer cooiosus, Microbisium confusum, and Fselanhochernes oarvus. The latter two were taken also in rotten loss and wood de- bris. Microbisium brunneum_was collected from Sphagnum moss ”no -—-—.—_ and bog debris.

  • Section IV – Guideline for the Texas Priority Species List
    Section IV – Guideline for the Texas Priority Species List Associated Tables The Texas Priority Species List……………..733 Introduction For many years the management and conservation of wildlife species has focused on the individual animal or population of interest. Many times, directing research and conservation plans toward individual species also benefits incidental species; sometimes entire ecosystems. Unfortunately, there are times when highly focused research and conservation of particular species can also harm peripheral species and their habitats. Management that is focused on entire habitats or communities would decrease the possibility of harming those incidental species or their habitats. A holistic management approach would potentially allow species within a community to take care of themselves (Savory 1988); however, the study of particular species of concern is still necessary due to the smaller scale at which individuals are studied. Until we understand all of the parts that make up the whole can we then focus more on the habitat management approach to conservation. Species Conservation In terms of species diversity, Texas is considered the second most diverse state in the Union. Texas has the highest number of bird and reptile taxon and is second in number of plants and mammals in the United States (NatureServe 2002). There have been over 600 species of bird that have been identified within the borders of Texas and 184 known species of mammal, including marine species that inhabit Texas’ coastal waters (Schmidly 2004). It is estimated that approximately 29,000 species of insect in Texas take up residence in every conceivable habitat, including rocky outcroppings, pitcher plant bogs, and on individual species of plants (Riley in publication).

  • Pseudoscorpions
    Colorado Arachnids of Interest Pseudoscorpions Class: Arachnida Order: Pseudoscorpiones Identification and Descriptive Features: Pseudoscorpions are tiny arachnids (typically Figure 1. Pseudoscorpion ranging from 1.25-4.5 mm body length). They possess pedipalps modified into pincers in a manner similar to scorpions. However, they differ in other features, notably possessing a broad, flattened abdomen that lacks the well developed tail and stinger. Approximately 200 species of pseudoscorpions have been described from North America. A 1961 review of pseudoscorpions within Colorado listed 30 species; however, these arachnids have only rarely been subjects for collection so their occurrence and distribution within Colorado is poorly known. The pseudoscorpion most often found within buildings is Chelifer cancroides, sometimes known as the “house pseudoscorpion”. It is mahogany brown color with a body length of about 3-4 mm and long pedipalps that may spread 8 mm across. Distribution in Colorado: Almost all pseudoscorpions that occur in Colorado are associated with forested areas although a few prairie species do occur. Conifer forests, including scrublands of pinyon and juniper, support several species. Others occur in association with Gambel oak and aspen. The house pseudoscorpion has an unusually broad distribution and is found associated with human dwellings over wide areas of North America and Europe. Life History and Habits: Pseudoscorpions usually occur under rocks, among fallen leaves or needles, under bark or similar moist sites where they hunt mites, springtails and small insects. Typically they wait in ambush within small crevices and grab passing prey with the pincers. In most species, connected to the movable “finger” of the pincer is a venom gland.

We examined 110 papers (from 1967 to 2018) to: (i) understand how cave-dwelling invertebrates have been sampled; (ii) provide a summary of techniques most commonly applied and appropriateness of these techniques, and; (iii) make recommendations for sampling design improvement. Of the studies reviewed, over half (56) were biological inventories, 43 ecologically focused, seven were techniques papers, and four were conservation studies. Nearly one-half (48) of the papers applied systematic techniques. Few papers (24) provided enough information to repeat the study; of these, only 11 studies included cave maps. Most studies (56) used two or more techniques for sampling cave-dwelling invertebrates. Ten studies conducted ≥10 site visits per cave. The use of quantitative techniques was applied in 43 of the studies assessed.
