Distinção de espécies de Amphimedon Duchassaing & Michelotti, 1864 (Niphatidae, Haplosclerida, Demospongiae) da costa brasileira por estudos de diversidade genética e morfológica
The taxonomy of Amphimedon is complicated due to its wide distribution and abundance of morphotypes. The objective of this work was to characterize the species of Amphimedon from the Brazilian Coast by the combined study of morphology and DNA polymorphisms. The samples utilized were derived from …

Towards a molecular approach for the identification of fungal taxa that contain psilocybin
… are based primarily on morphological traits. If the mushroom specimens are dried or pulverized, the morphological characteristics are frequently disguised or no longer apparent. Included among these fungi are known to produce psilocybin, which are hard to identify by their macroscopic …

Coevolution of Heliconius spp. and Passiflora spp. : a phylogenetic comparison
… was based on combined sequence data from rRNA ITS 2 and partial EF-1a gene regions. For the Passifloraceae, 17 host plant species were utilized to establish a phylogeny based on tRNALeucine and ITS 1/5.8S1 ITS 2 sequence data. The phylogenies for both groups were largely in agreement with …

Molecular Population Genetics of the Atlantic Sand Fiddler Crab, Uca Pugilator, Along the Atlantic Coast
… and the nuclear internal transcribed spacer 1 (ITS1) genes of these individuals. The ITS1 marker did not prove to be informative when screened by SSCP for this study. The 16S marker revealed a moderate amount of population structure (FST = 0.292) between populations. The results of this study …

T-RFLP analysis of bacterial 16S rRNA gene sequences isolated from river otter (Lontra canadensis) scat and parasite screening for the presence of Toxoplasma gondii
… nested PCR primer set for the detection of the ITS 1 region of Toxoplasma gondii. Scat samples used in the T-RFLP analysis were also tested for the presence ofT. gondii using the same nested primer set. Neither the river otter tissue samples nor any of the scat samples used in this analysis …

Phylogenetic Study of Apocynaceae Juss. And Aspidosperma Mart. And Zucc
… of morphological variation to establish basic units which were interpreted as species. A preliminary monograph of that genus Aspidosperma provides descriptions, exsiccatae, and distribution information for the thirty-six species that were recognized. The cladistic part of the systematic analysis …

Techno-economic assessment of jet fuel naphthalene removal to reduce non-volatile particulate matter emissions
… black carbon (BC) emissions. Given its 1-2 vol% concentration in jet fuel, there are several refining processes that may be used to remove naphthalene without impacting its ability to meet specification. This study evaluates the economic feasibility of jet fuel naphthalene removal …

Species-level phylogenetic reconstruction of the African cycad genus Encephalartos (Zamiaceae)
… of cycads. Sequences of the trnL intron, rpoC1, ITS 1, ITS 2, and AFLP profiles from two sets of selective primers were used to reconstruct the phylogenetic relationships within the genus using maximum parsimony methods. As in earlier studies, unresolved polytomies were recovered from the …

Distribution, Genetic Characterization, and Life History of the James spinymussel, Pleurobema collina (Bivalvia: Unionidae), in Virginia and North Carolina
… P. collina resides in VA and what the extent of its range is within the state. An informal preliminary survey design for P. collina was used during the summer of 2002 and simple random sampling was deployed in 2003-2004 surveys to provide a good basis for comparison to gauge the efficiency of the …
