Conservation International, the MacArthur Foundation, and others used the hotspots concept for a period of some eight years, based mainly no Myers two original papers (1988, 1990) and the map-based update by Conservation International. However, given the growing importance and acceptance of this concept in global biodiversity conservation planning and the fact that Conservation International intended to base a major fund-raising campaign on the hotspots, we felt that a reanalysis and reassessment of the hotspots was timely and appropriate. With this in mind, we organized a mini-workshop in the Washington, D. C. offices of Conservation International for a three-day period in March, 1996. The purpose of this exercise was to review the hotspots concept, reevaluate its validity, identify criteria for what constitutes a hotspot, add or subtract areas as appropriate, and begin a detailed data analysis to serve as an underpinning for future use of the concept. Some 20 experts were involved in this preliminary exercise, including the originator of the concept, Norman Myers... |

Avian infectious bronchitis virus (IBV) isolates have been widely characterized by reverse transcription followed by polymerase chain reaction and DNA sequencing. In present study, these techniques were applied to three viral genomic regions comprising the complete and/or a partial S1 segment, S2 and nucleocapsid genes. DNA sequences from viral isolates obtained from 1972 to 1989 and from 2006 to 2008 were compared. High similarity (>90%) was observed among some of the genomic segments, including S1 hypervariable region, which could suggest a common origin or ancestry. DNA sequences from S2 and N protein genes obtained from different infected tissues of the same flock were analyzed, and a clear segregation between respiratory and intestinal tract was observed. Therefore, these data suggest cocirculation of more than one viral strain in the same flock. 57.1% of DNA sequences from the S1 complete segment samples, 53.3% from the S2 fragment and 62.5% from the partial N gene were found to be different from analyzed sequences from reference strains leading to the conclusion that parte of viral isolates included in this study may be considered region specific. Considering the simultaneous analysis of the three genes, a large IBV genetic profile was observed in both old and recent isolates groups. However, most prominent diversity between viral isolates was obtained in the period from 1972 and 1989, showing the presence of a large number of variants in the state of Minas Gerais before the official approval of vaccination (1980).
