OUADRAMACULATUS (HOLBROOK) AT WHITETOP MOUNTAIN, VIRGINIA
Eugene V. Gourley and Charles M. Meal Department of Biology Radford University Radford, VA 24142
Leurognathus marmoratus Moore occurs from northeastern Georgia and the northwestern tip of South Carolina into the Great Smoky Mountains of Tennessee and North Carolina and in to southwestern V irg in ia . Three lo c a litie s have been reported fo r V irg in ia ; the Blue Ridge Parkway in Floyd County (Conant, 1975a, 1975b); Rig Branch, Smyth County (Hoffman and Hoffman, 1956); and Daves Branch, Smyth County (Gourley, 1979) (Figure 1).
Desmognathus guadramaculatus (Holbrook) has a distribution similar to U marmoratus but the northern edae of the range extends into southern West V irg in ia (Conant, 1975a) (Figure 2 ).

Solid in the southern Appalachian circle indicates location of Mountains. Solid circle study area. -4- indicates location of study area. The local distributions and extent of these two species are not v/ell known. This is o f p a rtic u la r concern fo r L. marmoratus because its status is currently listed as "of special concern*'1'n Virginia (Hoffman, 1979).
The study areas included 30 meter by 1 meter sections of Daves Branch north o f and adjacent to State Route 600. Both streams are tributaries of Big Laurel Creek and are swift mountain streams with rocky stubstrates located at an altitude of approximately 3600 fe e t. These streams seem to provide ideal hahitats for U marmoratus and CL guadramaculatus as described by Martof (1962).
M aterials and Methods
Adult Leurognathus marmoratus and Pesmognathus guadramaculatus were co lle cte d at weekly in te rv a ls between June 27 and July 26, 1981. Large and small rocks in the streams were turned quickly by hand and' salamanders were captured with a wire screen pressed closely to the substrate. Captured adults were identified to species and snout- vent length was determined by placing the salamanders in a test tube and measuring w ith a V ernier c a lip e r. In d ivid u a ls were marked by toe clipping and were released as close to the capture site as possible.
Population estimates (N) were determined usinq the weighted mean method, a modification of the Lincoln index for multiple mark, release and recapture (Regon, 1979). The equation for this calculation is:
N = ^ ^ i n i______Rm1-)+ 1
where n. = to ta l captures
m. = total caught and previously marked
M. = r . - m. i i i r . = number released
SE = N / \ 2 „ 6 . / J n . t l + (£m + l ) 1- + (X m1 + l ) 3
Results
During the study period a total of 30 Leurognathus marmoratus were marked and released in Daves Branch w ith fo u r recaptures*! Ten Pesmognathus guadramaculatus were recaptured out of 58 individuals marked and released. The weighted mean estimate of the Daves Branch L_. marmoratus population was 81 + S.E. 46. The D. guadramaculatus populations were estimated at 127 + S.E. 38. F ifte e n L. marmoratus were marked and released In Big Branch w ith five recaptures. The U marmoratus population was estimated at 22 + S.E. 11. Twenty seven D. quadramaculatus were marked and released w ith 13 recaptures. The Big Branch population of D_. quadramaculatus was estimated at 55 + S.E. 16. p The density of L. marmoratus was 2.7 individuals/meter In Daves Branch and 0.7 indivTduals/meter^ in Bin Branch. Desmognathus quadra maculatus 'had a density of 4.2 individuals/ meter2 in Daves Branch, and 1.8 individuals/ meter? in Rin Branch.
Snout-vent lengths of captured and marked salamanders are presented in Figure 3.

SNOUT-VENT LENGTH IN MM
Figure 3. Snout-vent lengths of Leurognathus marmoratus Moore In Big Branch (s o lid c irc le s ) and Daves Branch (open c irc le s ) and Desmognathus quadramaculatus (Holbrook) in Biq Rranch (s o lid squares) and Daves Branch (open squares). Conclusions
The snout-vent lengths of Desmognathus guadramaculatus and Leurognathus marmoratus were not s ig n ific a n tly d iffe re n t from the ranges given by Organ (1961) and Martof (1962, 1963).
The population estimates for Oesmognathus guadramaculatus were con sistently greater than the population estimates of L_. marmoratus in both streams, the greater number of D_. guadramaculatus may be due to the low stream levels a t the time o f th is in v e s tig a tio n . Desmognathus guadramac ulatus seems to prefer the edges of sw ift mountain streams where J-. marmoratus prefers rapids and ra p id ly moving water. For th is reason, dry periods seem to be more critica l for U marmoratus due to decreases in suitable habitat and the f). guadramaculatus population is favored when the salamanders are brought into increased competition with one another. When rainfall is more normal, competition is almost non existent (Martof, 1962).
The density of U marmoratus in both streams was lower than the density reported by Martof (1962) for Georgia streams. The low numbers o f L_. marmoratus may be due to increased com petition by f). guadramaculatus or may be due to location of these populations at the northernmost known lim it of their range. Additional field work is needed to determine the full extent, distributions, population dynamics and interactions of these two species.

THE VIRGINIA MONGAME SPECIES PROGRAM: REPTILES AMD AMPHIBIANS
Joseoh M itch e ll U n ive rsity o f Richmond Richmond, VA 23173
The Virginia legislature recently approved a tax w riteoff box for the 1031 Virginia income tax forms. This allows a Virqinia taxpayer who receives a refund to contribute part (or all) of that refund to the newly formed nongame program beinq developed by the Virginia Game and Inland Fisheries Commission. Monies received from these c o n trib u tio n s w ill fund the in itia l phase that involves the building of an Information data base on about 25D nongame species of Virqinia fish, amphibians, reptiles, birds, and mammals. A primary purpose is to educate the public about nongame species and their role in Virginia's environment. This data base would also be used to supply Information to various government and private groups on the faunal diversity and quality of areas of in te re s t.
The data base involves the use of a computer program (Biota of Virginia = BOVA) developed at VPI for large scale information storage and retrieval. Information on various apects of each species would he accumulated. This includes detailed distributional data, historical occurrence, population size and density, food habits, reproduction, habitat types, larval and adult habitats of amphibians, etc. The lis t of 250 is the in itia l listing chosen for the firs t phase of the program. At some later time other species would be added. Criteria for choosing a species are: 1) whether the species is known, or thought to be, in need of protection; 2) whether the species could be used as an ecoloqical in d ic a to r species to detect changes in h a b ita t q u a lity ; and 3) special considerations, such as health reasons (Poisonous snakes) or if the species were indicative of major distributional patterns in Virginia. Data would be accumulated as received from specialists on the species, the literature, and from specially funded research projects (a nlan for future program functions). Since public education seems to be of para mount importance, information booklets and articles w ill probably be written and distributed.
I was asked to advise the nongame people on herps th a t should appear on the lis t. They already had a preliminary lis t and after con siderable discussion we came up with the lis t below. Obviously not all
- 11- the species that probably should be on the firs t lis t were chosen. Also, not a ll o f the species lis te d in the VP! Endangered species book wore chosen. The l i s t is the combined attemnt to produce an assemblane o f species that would, based on the criteria above, be agreeable to the nongame people and herpetolooists. I think it is a representative lis t and is a start in the right direction. If you have any questions about the nongame prooram in Virginia, write to Robert W. Duncan or William E. Neal, Commission of Dame and Inland Fisheries, Anin West Broad S tre e t, Box 11104, Richmond, VA 23230.

The Ashtons have undertaken a tremendous task in attem pting to provide a comprehensive field guide to the herpetofauna of Florida. Not since Carr and Coin nublished their 1^55 work "Guide to amphibians and fresh water fishes of Florida" has there been an attempt to cover all of the states rentiles and amphibians.
"P art I : The Snakes" includes over 100 e xce lle n t co lo r photographs, distribution maps, drawings, and species accounts for all of the species of snakes found in Florida. The authors have included descrip tions and ohotoqraphs of almost every subspecies and color phase. In addition to the popular "dot in the county" range maps, the authors have also included a very valuable tahle listing the frequency of occurence of each species in the 21 different types of habitat found in the state. The book contains a wealth of information on the different types of habitats within the state, laws pertaining to amnhibians and rentiles, natural history and many other aspects of the herpetofauna of the state.
This book is a must not only fo r those inte reste d in the snakes o f Florida, but in snakes in general. We look forward to the ouhlication of Part II: Lizards, Turtles, and Crocodilians, and Part III: The Amphibians.
ANTIFREEZE IN FROGS!
An a r tic le th a t appeared re cently in Science (Feb. 5, 1982) entitled "Survival of frogs in low temperatures" renorted results that should be of interest to all VaHS members. Several species of anurans that normally overwinter in leaf litte r have been shown to produce glycerol during the fa ll and winter months that acts .iust as antifreeze in a cars radiator. Hyla versicolor, Hyla crucifer, and Rana sylvatica a ll produced glycerol whereas two species th a t norm ally overw inter in aquatic habitats (Rana septentrional is and Rana pipiens) did not produce glycerol. The three species of terrrestrial overwintering frogs were able to survive beinq frozen fo r 5-7 days w ith body temp eratures of -6°G and over 35?, of their body water frozen! Previous research has shown that the overwintering sites occupied by these species often reach these temperatures.

Dear Herpetologist, v It has come to my notice that you have an interest in reptiles and their as sociated biology. With protective legislation now enacted in all Australian States, the emphasis on breeding captive stocks has increased markedly. The importance of the captive breeding of Australian reptiles, particularly snakes, will without doubt, increase in future. Many herpetologists, particularly those new to the field, have no readily available source of literature available on how to breed snakes. This is a surprising state of affairs considering how many times snakes have been bred in captivity in this country. It is also surprising that next to nothing has been published on the subject.
This present Australia wide Survey hopes to collect and subsequently pool as much known information on captive breeding of snakes as possible. The results will be published in a similar format to that used by Richard Ross in his popular "Python Breeding Manual", an American publication.
In order for this survey to be a success, it requires the co-operation of all herpetologists including yourself. It would be appreciated that if you have bred any kind of Australian snake in captivity you could fill out one questionnaire. These questionnaires are necessarily lengthy due to the importance of collecting all relevant data. Please report all data as accurately as possible.
Please fill out a separate questionnaire per breeding if you have been fortunate enough to have bred snakes more than once. The results of this survey will probably be published in approximately one year.
If you know of other herpetologists who have bred Australian snakes, please ask them to fill out a questionnaire also. When filled out please return each questionnaire to:
• Snake Breeding Survey, 60, Arterial Road, St. Ives, N.S.W. 2075. Australia
If more questionnaires are required, simply send a request for extra copies to the above address or phone (Sydney) 449 5771. Thanking you for your co-operation,
Yours sincerely,
Raymond I loser -IP,-
