Reddell and Robert W. Mitchell Department of Biology Texas Tech University Lubbock, Texas INTRODUCTION In view of the ever-increasing interest in all studies relating to the water resources of Texas, we have found it timely to prepare this guide to the fauna and biological literature of our subterranean waters. The value of such a guide has already been demonstrated by Clark (1966) in his "Publications, Personnel, and Government Organizations Related to the Limnology, Aquatic Biology and Ichthyology of the Inland Waters of Texas". This publication dea ls primarily with inland surface waters, however, barely touching upon the now rather extensive literature which has accumulated on the biology of our subterranean waters. To state a n obvious fact, it is imperative that our underground waters receive the attention due them. They are one of our most important resources. Those subterranean waters for which biological data exi st are very un­ equally distributed in the state. The best known are those which are acces­ sible to collection and study via the entrances of caves. Even in cavernous regions there exist inaccessible deep aquifers which have yielded little in­ formation as yet. Biological data from the underground waters of non-cave rn­ ous areas are virtually non-existant.

  • SQUIRREL CHIMNEY CAVE SHRIMP Palaemonetes Cummingi
    SQUIRREL CHIMNEY CAVE SHRIMP Palaemonetes cummingi (Photo unavailable) FAMILY: Palaemonidae STATUS: Threatened (Federal Register, June 21, 1990) DESCRIPTION: The Squirrel Chimney Cave shrimp, also known as the Florida cave shrimp, is approximately 1.2 inches (3O millimeters) long. Its body and eyes are unpigmented; the eyes are smaller than those of related surface-dwelling species of Palaemonetes. RANGE AND POPULATION LEVEL: This cave shrimp is known only from a single sinkhole (Squirrel Chimney) in Alachua County, Florida. No more than a dozen individuals have been seen near the surface of the sinkhole water table, but more individuals may exist at greater depths. HABITAT: Squirrel Chimney is a small, deep sinkhole that leads to a flooded cave system of unknown size. The sinkhole is known to support one of the richest cave invertebrate faunas in the nation. Other cave invertebrates found in this sinkhole include McLane's cave crayfish (Troglocambarus maclanei); the light-fleeing cave crayfish (Troglocambarus lucifugus); the pallid cave crayfish (Procambarus pallidus); and Hobb's cave amphipod (Crangonyx hobbsi). These species are found in the shallower portions of a pool in the fissure leading off the sinkhole. They usually cling bottom-side-up to limestone just beneath the water table. These species are adapted for survival in a nutrient-poor, detritus-based ecosystem. REASONS FOR CURRENT STATUS: The Squirrel Chimney Cave shrimp is endemic to a single sinkhole. Any changes in the sinkhole or cave system could eliminate the species. The site is privately owned and the owners are currently protecting the site from trespassers. Urban development associated with the growth of Gainesville, Florida are expected to continue and will most likely alter land use practices in the vicinity of Squirrel Chimney Cave.

  • Influence of Starvation on the Larval Development of Hyas Araneus (Decapoda, Majidae)*
    HELGOL~NDER MEERESUNTERSUCHUNGEN Helgol~inder Meeresuntersuchungen 34, 287-311 (1981) Influence of starvation on the larval development of Hyas araneus (Decapoda, Majidae)* K. Anger I & R. R. Dawirs 2 I Biologische Anstalt Helgoland (Meeresstation); D-2192 Helgoland, Federal Republic of Germany 2 Zoologisches Institut der Universit~t Kiel; Olshausenstral]e 40-60, D-2300 Kiel 1, Federal Republic of Germany ABSTRACT: The influence of starvation on larval development of the spider crab Hyas araneus (L.) was studied in laboratory experiments. No larval stage suffering from continual lack of food had sufficient energy reserves to reach the next instar. Maximal survival times were observed at four different constant temperatures (2°, 6 °, 12 ° and 18 °C). In general, starvation resistance decreased as temperatures increased: from 72 to 12days in the zoea-1, from 48 to 18 days in the zoea-2, and from 48 to 15 days in the megalopa stage. The length of maximal survival is of the same order of magnitude as the duration of each instar at a given temperature. "Sublethal limits" of early starvation periods were investigated at 12 °C: Zoea larvae must feed right from the beginning of their stage (at high food concentration) and for more than one fifth, approximately, of that stage to have at least some chance of surviving to the next instar, independent of further prey availability. The minimum time in which enough reserves are accumulated for successfully completing the instar without food is called "point-of-reserve-saturation" (PRS). If only this minimum period of essential initial feeding precedes starvation, development in both zoeal stages is delayed and mortality is greater, when compared to the fed control.

  • Observations on the Biology of the Endangered Stygobiotic Shrimp Palaemonias Alabamae, with Notes on P. Ganteri (Decapoda: Atyidae)
    Subterranean Biology 8: 9-20, 2010 (2011) Stygobiotic shrimp Palaemonias alabamae 9 doi: 10.3897/subtbiol.8.1226 Observations on the biology of the endangered stygobiotic shrimp Palaemonias alabamae, with notes on P. ganteri (Decapoda: Atyidae) John E. COOPER (1,*), Martha Riser COOPER (2) (1) North Carolina State Museum of Natural Sciences, Research Lab, 4301 Reedy Creek Road, Raleigh, NC 27607, U.S.A.; e-mail: [email protected] (2) 209 Lynwood Lane, Raleigh, NC 27609, U.S.A.; e-mail: [email protected] *Corresponding author ABSTRACT Palaemonias alabamae is endemic to subterranean waters in northern Alabama. Its type locality is Shelta Cave, Madison County, and ostensibly conspecifi c shrimps have been found in Bobcat and two other caves. Pollution and other factors may have extirpated the shrimp from the type locality. In Shelta Cave the species is smaller than the shrimp in Bobcat Cave and P. ganteri in Mammoth Cave, Kentucky. Adult female P. alabamae (s.s.) and P. ganteri are larger than males. Female P. alabamae with visible oocytes or, rarely, attached ova, were observed from July through January in Shelta Cave. Each female there produces 8 to 12 large ova, whereas females of the population in Bobcat Cave produce 20 to 24 ova, and P. ganteri produces 14 to 33 ova. Plankton samples taken in Shelta and Mammoth caves yielded nothing identifi able as zoea or postlarvae. Palaemonias alabamae and P. ganteri usually feed by fi ltering bottom sediments through their mouthparts, but both sometimes feed upside down at the water’s surface. Although there is some overlap, the compositions of the aquatic communities in Shelta and Mammoth caves differ, and there are some major dif- ferences among the Alabama shrimp caves.

  • Limited Appearance Statement of Susan Woods Regarding Levy
    DOCKETED USNRC January 13, 2012 (10:15 am) OFFICE OF SECRETARY RULEMAKINGS AND ADJUDICATIONS STAFF I know you all are aware that building nuclear plants so close to the Gulf of Mexico, and on fragile coastal ecosystems, requires the utmost care in selecting sites and plans for construction. Any mistakes that result in damage to the Gulf Coast ecosystems will surely create an uproar on the scale of the BP oil spill. There are many of us here today who can comment on the science of that with more expertise than I have. My mission today is to remind all of you that you have a responsibility not only to the folks who will live within the shadow of the new nuclear plants, but also to those who cannot speak for themselves, and who are perhaps not even recognized by most of us. For this reason, I have given you copies of a paper written by Stephen J. Walsh of the US Geological Survey entitled Freshwater Macrofauna of Florida Karst Habitats. The aim of the paper is to emphasize several very important points: 1. You must understand that what affects salt water, as in the Gulf of Mexico, also affects freshwater habitats, as the water from the Gulf interacts significantly with the water of the Floridan Aquifer in the location you have chosen. 2. With the exception of those parts of Florida that have already used up freshwater resources in their area, and who have already turned to desalinization, the Floridan Aquifer is THE source of fresh water for all Floridians who live in the western half of the state.

  • An Enumeration of the Crustacea Decapoda Natantia Inhabiting Subterranean Waters
    / s £ Qtaam m !957 CTttSW^ AN ENUMERATION OF THE CRUSTACEA DECAPODA NATANTIA INHABITING SUBTERRANEAN WATERS par L.-B. HOLTHUIS Rijksmuseum van Natuurlijke Historie, Leiden, Holland The present paper provides a list of the macrurous Decapod Crustacea, belonging to the supersection Natantia, that have been found in subterranean waters. The number of such species is quite small, being somewhat more than 40 in all. Of these only part are actual troglobic forms, i.e. animals that are only known from caves and have not, or only incidentally, been found in waters that are exposed to daylight. A second group is formed by species that normally live in surface waters and only occasionally are met with in subterranean habitats. No sharp line can be drawn between these two categories, the more so as at present still extremely little is known of the biology and of the ecology of most of the species. Nevertheless it was thought useful to try and make in the present paper a distinction between these two groups, of each of which a separate list is given enumerating the species in systematic order. In the first list the true troglobic forms are dealt with, the second contains those species which must be ranged under the incidental visitors of subterranean waters. Of the species placed in list I a complete synonymy is given, while also all the localities whence the species has been reported are enumerated. Furthermore remarks are made on the ecology and biology of the animals as far as these are known. In the second list only those references are cited that deal with specimens found in subterranean waters, while also some notes on the ecology of the animals and the general distribution of the species are provided.
