Ecological Niche Modeling Of Two Scorpion Species Mesobuthus Eupeus (C. L. Koch, 1839) And M. Phillipsii (Pocock, 1889) From The Iranian Plateau And Zagros Region (Arachnida: Scorpiones), Omid Mirshamsi

Euscorpius

Ecological niche modeling has allowed several advances in the process of species delimitation. In the present study, I used this method to evaluate the climatic divergence between two scorpion species, Mesobuthus eupeus and M. phillipsii. The ecological niche models (ENMs) were created based on presence-only data with the maximum entropy method. The created models, results of spatial analysis (PCA and Hotelling discriminant), and an identity test suggested that the divergence between these two species is associated with significant divergence in their ecological niches. The results of this study provide additional support for the taxonomic validity the studied species.

A New Species Of Tityus C. L. Koch, 1836 (Scorpiones: Buthidae) From Dominican Amber, Wilson R. Lourenço

Euscorpius

Tityus azari sp. n., a new species of fossil scorpion belonging to the genus Tityus C. L. Koch, 1836 is described based on a specimen in amber from the Dominican Republic. Although the new species can be associated with the extant fauna of the Neotropical region, it presents some particular morphological features such as the presence of sharp denticles on the edge of pedipalp fingers. Due to the incompleteness of the specimen it cannot be assigned to any precise extant subgenera. Once again, this discovery attests to a considerable degree of diversity in the Dominican amber-producing forests.

Horses were domesticated from the Eurasian steppes 5,000–6,000 years ago. Since then, the use of horses for transportation, warfare, and agriculture, as well as selection for desired traits and fitness, has resulted in diverse populations distributed across the world, many of which have become or are in the process of becoming formally organized into closed, breeding populations (breeds). This report describes the use of a genome-wide set of autosomal SNPs and 814 horses from 36 breeds to provide the first detailed description of equine breed diversity. F_ST calculations, parsimony, and distance analysis demonstrated relationships among the breeds that largely …

On The Morphology And Taxonomy Of Griphobilharzia Amoena Platt And Blair, 1991 (Schistosomatoidea), A Dioecious Digenetic Trematode Parasite Of The Freshwater Crocodile, Crocodylus Johnstoni, In Australia [Critical Comment], Thomas R. Platt, Eric P. Hoberg, Leslie A. Chisholm

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Griphobilharzia amoena Platt and Blair, 1991 was originally described was originally described as a dioecious trematode, parasitic in the circulatory system of the Australian freshwater crocodile, Crocodylus johnstoni, with the female completely enclosed in a gynecophoric chamber of the male and the two worms orientated anti-parallel to each other. A recent publication questions the original description, arguing that G. amoena is monoecious and, as a consequence, the species was transferred to Vasotrema Stunkard, 1928 (Spirorchiidae) as Vasotrema amoena n. comb. We provide photomicrographic evidence that the original description of G. amoena is correct and that Griphobilharzia Platt and Blair, …

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. …

How The Leopard Hides Its Spots: Asip Mutations And Melanism In Wild Cats, Alexsandra Schneider, Victor A. David, Warren E. Johnson, Stephen J. O'Brien, Gregory S. Barsh, Marilyn Menotti-Raymond, Eduardo Eizirik

Biology Faculty Articles

The occurrence of melanism (darkening of the background coloration) is documented in 13 felid species, in some cases reaching high frequencies at the population level. Recent analyses have indicated that it arose multiple times in the Felidae, with three different species exhibiting unique mutations associated with this trait. The causative mutations in the remaining species have so far not been identified, precluding a broader assessment of the evolutionary dynamics of melanism in the Felidae. Among these, the leopard (Panthera pardus) is a particularly important target for research, given the iconic status of the ‘black panther’ and the extremely …
