Major evolutionary events in the origin and diversification . . . the genus Polystichum More than 82 different hybrid com-binations between Polystichum species have been recognized (Knobloch, 1996) As expected, most of these hybrids are to-tally sterile (Manton, 1950; Nakaike, 1973; Wagner, 1973, 1979; Daigobo, 1974; Barrington, 1985, 1990; Barrington et al , 1989) However, swarms of fertile hybrids
Ocean Discoveries Are Revising Long-Held Truths about Life For more than 50 years deep-sea exploration has been a continuous fount of discoveries that change how we think about life in the ocean, on dry land and even beyond our planet Consider the
Prepared for US Fish and Wildlife Service Prepared by - WA - DNR have higher prediction accuracy, but are more difficult to interpret than CART models due to the averaging of tree data (Franklin 2009) Our intent was to identify additional areas of suitable habitat for whitebark pine beyond the areas where the species has been documented by plot, herbarium, or observation data The modeled

Global species numbers of fungi: are tropical studies and . . . Recent estimates of the global species numbers of fungi suggest that the much-used figure of 1 5 million is low, and figures up to 5 1 million have been proposed in the last few years Data emerging from tropical studies, and from large-scale sequencing of environmental samples, have the potential to contribute towards a more robust figure Additional evidence of species richness is coming
