| Strains of Xylella fastidiosa from several hosts (coffee, citrus, grape, almond, oleander, peach, plum, etc.) were characterized by analyzing the content of the nucleotide sequences of 16S-23S rDNA (coding for a small subunit ribosomal RNA) spacer region (ITS). Current methods for sequencing the ITS region yields partial sequences that do not contribute with significant information. According to this fact, new primers have been designed in order to obtain a complete sequence and facilitate the sequencing. The complete 16S-23S sequences from 08 strains were amplified through PCR using the primers designed in our lab. The 16S-23S sequences obtained were compared with 52 others sequences entries in GenBank database. The results revealed a higher level of... |

| A novel thermoacidophilic iron and sulfur-oxidizing archaeon, strain YN25, was isolated from an in situ enriched acid hot spring sample collected in Yunnan, China. Cells were irregular cocci, about 0.9-1.02 µm×1.0-1.31 µm in the medium containing elemental sulfur and 1.5-2.22 µm×1.8-2.54 µm in ferrous sulfate medium. The ranges of growth and pH were 50-85 (optimum 65) and pH 1.0-6.0 (optimum 1.5-2.5). The acidophile was able to grow heterotrophically on several organic substrates, including various monosaccharides, alcohols and amino acids, though the growth on single substrate required yeast extract as growth factor. Growth occurred under aerobic conditions or via anaerobic respiration using elemental sulfur as terminal electron acceptor. Results of... |

| In certain times of the year, Actinote butterflies can be vastly abundant in Southeastern Brazil, thus representing conspicuous denizens of our fauna. Their wing coloration allows for the recognition of five major patterns, which probably resulted from mimicry. Furthermore, examination of series of field-collected and reared specimens clearly demonstrates a high intra-specific variation in wing color pattern. In concert, inter-specific resemblance (mimicry) and intra-specific variation make it difficult to discriminate Actinote species from each other. This key aims at providing a tool for identification of male Actinote. To that effect, we provide diagnostic characters and illustrations of wings and male genitalia for 22 species. We hope that the clear... |

| To investigate the feasibility of application of digital images of the palatal rugae in forensic identification. One hundred patients, consisting of 50 males and 50 females, who received treatment between January 2015 and June 2015 at Shanxi Medical University Stomatological Hospital, China, were included in this study. High-resolution digital image of the palatal rugae was taken from each patient using a digital SLR camera and then processed using a digital image recognition system, including noise reduction, contrast enhancement, image segmentation, feature extraction, edge detection and information matching. Using an MATLAB software system, match results and the time taken by each operator for information matching were recorded. The digital image... |

| Periodicamente o Brasil é visitado por milhares de aves que realizam movimentos sazonais da América do Norte para a América do Sul e vice-versa (Sick 1983, Morrison et al. 1989, Chesser 1994). Dentre as aves que visitam o território nacional, destacam-se aquelas que migram com a proximidade do inverno boreal (Antas 1994). Os migrantes vêm ao Brasil à procura de locais de invernada, onde encontram alimentação farta, propiciando-lhes a continuidade do seu ciclo de vida (Telino Jr. et al. 2003). Estas aves apresentam extraordinária capacidade de percorrer longas distâncias (Hayman et al. 1986; Antas 1989; Morrison et al. 1989; Sick 1983, 1997; Azevedo Jr. et al. 2002, Alerstan et al. 2003). No período de inverno, a baixa oferta de recursos alimentares aliada... |

| The NAHMS Beef '97 Study was designed to provide both participants and the industry with information on the nation's cow-calf population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically-valid sample yielding 2,713 producers from 23 states. The 23-state target population represented 85.7 percent of U.S. beef cows on January 1, 1997, and 77.6 percent of U.S. beef operations. NASS enumerators collected data for this report via a questionnaire administered on-farm from December 30, 1996, through February 3, 1997. Contact for this paper: David Dargatz |

| Section 1 of this report shows demographic changes of the U.S. beef cow-calf industry from a historical perspective from data provided by the National Agricultural Statistics Service (NASS) and Census of Agriculture. Results of two NAHMS national studies in Section II complete the overview of change in the U.S. beef cow-calf industry during the 5-year period from 1993 to 1997. NAHMS, CHAPA Phase I included data collected from 2,539 cow-calf operations in the 48 continental states via telephone during the fall of 1992. Subsequent data collection was done on operations in 18 states and from producers with five or more beef cows and 50 percent or more of their calf crop born between January 1 and June 30 (spring calving) The 18 states represented 70... |
