Zerconella (Zerconella) Balkanica Sp. Nov., A New Species Of Zerconidae (Acari: Mesostigmata) From Central Albania, Zsolt Ujvári

Turkish Journal of Zoology

One new species, Zerconella (Zerconella) balkanica sp. nov., is described as the second species of the subgenus Zerconella (Zerconella) Willmann, 1953 on the basis of 5 specimens collected in the Dejë Mountains in central Albania. The new species shows a close morphological relationship to Zerconella (Zerconella) leitnerae Willmann, 1953, but can be distinguished from the latter by the absence of setae J4, the position of setae J5, and the size of the dorsal cavities. Geographic distribution of the subgenus Zerconella (Zerconella) is presented.

Diversity Indices Of Pelagic Rotifers In Camp Balloki Water Park, Lahore, Pakistan, Abdul Qayyum Khan Sulehria, Muhammad Anwar Malik

Turkish Journal of Zoology

This work attempted to evaluate the rotifer species diversity indices of Camp Balloki Water Park and infer the state of the water according to rotifers and physicochemical parameters. The diversity indices, species richness, and evenness were assessed every month. The Shannon–Weaver index indicated that this habitat had great diversity of rotifers throughout the year. These results were supported by the Simpson dominance, diversity, and reciprocal indices. Water and plankton samples were taken monthly from January 2006 to December 2006. In total, 38 rotifer species of 20 genera and 13 families were identified. Brachionus, Lecane, and Trichocerca dominated the locality. Rotifer …


Using Digital Images In The Study Of Fluctuating Asymmetry In The Spur-Thighed Tortoise Testudo Graeca, Gabriel Buica, Dan Cogalniceanu Jan 2013

Using Digital Images In The Study Of Fluctuating Asymmetry In The Spur-Thighed Tortoise Testudo Graeca, Gabriel Buica, Dan Cogalniceanu

Turkish Journal of Zoology

Fluctuating asymmetry has been proposed as a useful noninvasive tool for detecting the influence of the environment on body development. In the present study, we used digital images to estimate the fluctuating asymmetry of the plastron in an isolated Testudo graeca population in Dobrogea, Romania. We extracted data from the photos regarding the area, height, and width of 3 plastron scutes. A total of 155 adult tortoises analysed showed reduced variation in plastron asymmetry and no significant relationship was detected between fluctuating asymmetry and sex or body size. We suggest that fluctuating asymmetry may be an individual trait, with no …

A Reassessment Of The Conservation Status Of A Critically Endangered Neotropical Frog, Mannophryne Olmonae, Using Occupancy Modeling Techniques, Jessica Mcquigg Jan 2013

A Reassessment Of The Conservation Status Of A Critically Endangered Neotropical Frog, Mannophryne Olmonae, Using Occupancy Modeling Techniques, Jessica Mcquigg

Senior Independent Study Theses

Amphibian species worldwide are threatened with decline and extinction, making species monitoring an important scientific endeavor. The Bloody Bay Poison Frog, Mannophryne olmonae, a Tobago island endemic, was identified as critically endangered by the IUCN in 2004. Recent evidence suggests that a less severe conservation status may be appropriate for M. olmonae. This study employs acoustic calling surveys, land-use information, and multi-year (2011 and 2012) occupancy modeling techniques to propose an appropriate conservation status for this species. This study suggests that M. olmonae occupies a larger geographic range than was previously thought, and is not experiencing population declines. …

Chemical Defense Of An Asian Snake Reflects Local Availability Of Toxic Prey And Hatchling Diet, D. A. Hutchinson, A. H. Savitzky, G. M. Burghardt, C. Nguyen, J. Meinwald, F. C. Schroeder, A. Mori

Biological Sciences Faculty Publications

Species that sequester toxins from prey for their own defense against predators may exhibit population-level variation in their chemical arsenal that reflects the availability of chemically defended prey in their habitat. Rhabdophis tigrinus is an Asian snake that possesses defensive glands in the skin of its neck (nuchal glands'), which typically contain toxic bufadienolide steroids that the snakes sequester from consumed toads. In this study, we compared the chemistry of the nuchal gland fluid of R.tigrinus from toad-rich and toad-free islands in Japan and determined the effect of diet on the nuchal gland constituents. Our findings demonstrate that captive-hatched juveniles …


Exploring The Sulfide Tolerance Of Ectosymbiotic Niphargus Amphipods From The Frasassi Caves, Central Italy, Jan Bauermeister, Karoline Assig, Sharmishtha Dattagupta Jan 2013

Exploring The Sulfide Tolerance Of Ectosymbiotic Niphargus Amphipods From The Frasassi Caves, Central Italy, Jan Bauermeister, Karoline Assig, Sharmishtha Dattagupta

International Journal of Speleology

Two species of the crustacean amphipod genus Niphargus inhabit the sulfidic groundwaters of the Frasassi caves in central Italy, and both harbor filamentous, sulfide-oxidizing Thiothrix ectosymbionts. As sulfide is toxic to most aerobic organisms, it appeared possible that the ectosymbionts could help their Niphargus hosts with detoxification processes. In this study, mortality due to sulfide was compared between Niphargus individuals with ectosymbionts and individuals whose ectosymbionts had been killed by antibiotic treatment. Both Frasassi-dwelling Niphargus species revealed exceptionally high tolerances to sulfide compared to other amphipod species studied so far. Niphargus individuals without viable ectosymbionts tolerated sulfide levels exceeding those …
