Week 5: Populations That Slither!

Scholars!

With the recent approval of our Herpetological Survey by our beloved principal Ms. Bryan, I got excited about finding some of our slithering friends. For this weeks post, post the link to a study that has done a similar survey and describe their population sampling methods.

Happy Hunting

Mr. D

    This survey was completed under very specific conditions. The cloud cover was not at or over fifty percent, there was less than 15 mph wind, also the temperature was fifty to eighty degrees farenheight. The board was lifted with a snake hook for safety reasons. THis survey found new species of snakes the surveyers are actually monetoring the eastern massasauga rattlesnake.

    A Herpetological Survey was conducted at the University of Missouri at Columbia. The buffer zones that surround wetlands and riparian habitats are critical to the management of natural resources. These terrestrial areas that surround wetlands are core habitats for many semi-aquatic species. Local breeding populations define these core habitats. This survey provides an estimate of how many amphibians and reptiles reside in the wetlands and buffer zones. The data collected indicates that the habitats are important because they provide reptiles and other slippery friends with a place to feed and nest.

    Sampling Method Results:
    19 frog and 13 salamander species represent 1363 individuals.
    5 snake and 28 turtle species represent more than 2245 individuals.
    Core terrestrial habitat: 159 to 290 m for amphibians and 127 to 289 m for reptiles.

    There has been evidence that the native Okinawan Tree Frog, Rhacophorus viridis, has been disappearing on Yoronjima Island of the Ryukyu Archipelago.

    there was a herpetological survey conducted in the Yawkee wildlife park, the people conducting the survey were trying to get a better idea of the types of species on the islands, and how many of those species they found. The survey was conducted on three small islands. After one year of sampling at the Yawkey Wildlife Center 33 total species have been found on the property. 32 were found on Cat Island and 7 on South Island, using a variety of sampling techniques.

    They use a variety of standard herpetological survey such as drift fences, quadrats, calling surveys, visual encounter surveys, road cruises, and turtle traps.

    They found northern leopard frogs (Rana pipiens).

  9. In 1999, three groups,The Savannah River Ecology Lab, the United States Forest Service and the South Carolina Department of Natural Resources began a Herp study of the Sumpter National Forest. Fourteen sites were set up around the site along streams and ten metal and ten tarpaper coverboards were set up at each site. Once a month the boards were checked for herpetofauna samples as well as rocks, logs and other objects around the streams. In the end, a total of 287 organisms from 27 different species were collected, and it was found that more of the organisms were found within five meters of the stream.

  10. Robert C. Jadin, who works in the department of ecology and evolutionary biology at University of Colorado at Boulder, decided to conduct a herpetological survey with fellow graduates from varies colleges. He used methods such as using line and strip transects, drift fences, placing tin and cover boards, and hand capture of specimens to retrieve his results. By conducting this survey he hoped not only to find out what varies types of fauna thrives in his testing site, but also what types of predation might occur.

    A group of four scholars teamed up to conduct a herpetological survey in Southern Africa back in 2006. On the first day, a Mfezi, also known as Mozambique Spitting Cobra, was captured by one their funnel traps. By the end of their trip, the whole crew recorded 21 species of lizard, 15 species of snake, 3 species of chelonians, a crocodile, and 7 species of frogs. It didnt necessarily say what traps they used to capture these reptiles and amphibians but it does give a great detail of their experience through out their wildlife journey.

    There was a herpetological survey at the Wind Cave National Park. For this study they surveyed all the types of amphibous and reptilian species present in the Park. These included turtles, snakes, frogs, and others. Also there were many techniques used other than the kind of survey technique we are using. They are using drift fences, quadrats, calling surveys, visual encounter surveys, road cruises, and turtle traps.

    The purpose this herpetological survey at the Yawkey Wildlife Center is to identify all species of reptiles and amphibians that occur on the property. According to range maps, 101 reptile and amphibian species' ranges include the area of the Yawkey Wildlife Center. During the course of this survey it is important to utilize methods that cover broad areas, diverse habitats, as well as uncover as many species as possible. Due to the diversity of species that could occur on the Yawkey Wildlife Center property it is important to sample using a variety of techniques to discover the highest percentage of species. After one year of sampling at the Yawkey Wildlife Center 33 total species have been found on the property. 32 were found on Cat Island and 7 on South Island, using a variety of sampling techniques.

    This group used the pitfall method to trap their studies. They camoflouged a hole and the reptile would fall in and get trapped.

    This company, Stuart Spray, conducts herpetological surveys. An excerpt from what they do exactly as far as reptiles go is: "Reptiles

    To determine presence or likely absence of reptile species, there should be a minimum of seven survey visits between mid/late March and late June and/or between late August and late September during appropriate weather conditions.

    Adult reptiles should be located by searching under potential refugia such as stones, logs and debris such as sheets of metal.
    Corrugated tin sheets should be placed in suitably sunny areas of the site and regularly checked over the survey period looking for basking reptiles on top of the tin sheets and resting adder under the tin sheets."

    Thia site shows many different snakes from all over america. i chose this snake because of there way to lure the snake in. the snake is apart of the kingsnake family. they eat other snakes and dominate most of the territroy they are in. these biologists brought in other snakes that would attract the kingsnake to the site. these intoduced snakes were mostly prey to the kingsnake.

    Abstract;A survey of the population of the black howler monkey (Alouatta pigra) present at the Mayan site of Palenque was conducted during 2000. A total of 911 man/hours, spread over 112 days were spent surveying the 600ha area of pristine forest at the site for howler troops. We detected the presence of 136 individuals of which 131 were members of 20 troops, the rest were 3 solitary adult males and 2 adult males travelling as a pair. Ecological density was estimated at 23 individuals/km2. Mean troop size was 7.0 individuals and it ranged from 2-12 individuals; 60% of the troops were multimale. All sighting of howler monkeys were in evergreen rain forest and 75% were in trees .GEQ.20min height. The reported densities and mean troop size are higher than those reported for the species in Guatemala and in central Quintana Roo, Mexico. The vegetation of the forest contains tree species reported to be used by species of Alouatta in the Moraceae, Sapotaceae, Leguminosae, and Lauraceae plant families. Protection of a large perimeter area (ca 1700ha) around the archeological site by the Mexican government ensures the conservation of the forest and of the black howler monkey population present at the site.

    For over ten years, Cabrillo National Monument has been involved in a cooperative effort to monitor the health and population status of “herps.” Sampling occurs once a month for four survey nights per session with the help of volunteers. In addition to the pitfall traps and funnel traps used for snake capture as referenced in the USGS report, boards approximately three-foot square are placed near each array arm. These are checked each day in association with the pitfall traps to check specifically for California legless lizards (Anniella pulchra) and smaller snakes.

    Data is collected and recorded in the field using handheld “Palm” personal computers and associated datasheets.

    To evaluate their
    sampling efficiency they measured the time, in men hours (m/h) looking for amphibians at a
    certain place. More time for investigation was spent in complex and larger habitats, than in
    small and uniform ones. Tab. 1 and 2 summarize sampling time and date for all habitats
    investigated. Reptiles were recorded opportunistically while monitoring amphibians. A few
    voucher specimens, from both amphibians and reptiles, were collected. All vouchers were
    anesthetized and killed in a chlorbunatol solution and thereafter preserved in 70 % ethanol.
    Vouchers will be deposited in the collection of the Staatliches Museum für Naturkunde
    Stuttgart.
