genetics of sprouting: effects of long-term persistence in fire-prone ecosystems. | fire functional traits (postfire resprouting and seeding) are considered to be adaptations for persisting in fire-prone environments. although ecological and evolutionary consequences of sprouting have been extensively discussed, within-species genetic variability and structure are unknown. here we report levels and distribution patterns of genetic polymorphisms in postfire stands of the predominant sprouter nothofagus antarctica. fresh foliage of 50 individuals was collected following a spatial ... | 2008 | 18662228 |
lachancea nothofagi sp. nov., a yeast associated with nothofagus species in patagonia, argentina. | six strains of a novel yeast species were isolated from nothofagus species trees in native forests in patagonia, argentina. the strains were isolated from bark, fluxes and the ectomycorrhizospheric soil fraction of nothofagus antarctica, nothofagus nervosa and nothofagus pumilio. analysis of the d1/d2 large-subunit rdna sequences indicated that the novel species belonged to the genus lachancea and is closely related to lachancea meyersii. the name lachancea nothofagi sp. nov. is proposed to acco ... | 2010 | 19837734 |
permanent genetic resources added to molecular ecology resources database 1 october 2009-30 november 2009. | this article documents the addition of 411 microsatellite marker loci and 15 pairs of single nucleotide polymorphism (snp) sequencing primers to the molecular ecology resources database. loci were developed for the following species: acanthopagrus schlegeli, anopheles lesteri, aspergillus clavatus, aspergillus flavus, aspergillus fumigatus, aspergillus oryzae, aspergillus terreus, branchiostoma japonicum, branchiostoma belcheri, colias behrii, coryphopterus personatus, cynogolssus semilaevis, cy ... | 2010 | 21565039 |
ecology of cultivable yeasts in pristine forests in northern patagonia (argentina) influenced by different environmental factors. | environmental factors influencing the occurrence and community structure of soil yeasts in forests are not well studied. there are few studies dedicated to southern hemisphere soil yeasts populations and even fewer focused on temperate forests influenced by volcanic activity. the present work aimed to study the ecology of soil yeast communities from pristine forests influenced by different environmental factors (precipitation, physicochemical properties of soil, tree species, soil region, and se ... | 2014 | 24849380 |
heavy metal and trace elements in riparian vegetation and macrophytes associated with lacustrine systems in northern patagonia andean range. | vegetation associated with lacustrine systems in northern patagonia was studied for heavy metal and trace element contents, regarding their elemental contribution to these aquatic ecosystems. the research focused on native species and exotic vascular plant salix spp. potential for absorbing heavy metals and trace elements. the native species studied were riparian amomyrtus luma, austrocedrus chilensis, chusquea culeou, desfontainia fulgens, escallonia rubra, gaultheria mucronata, lomatia hirsuta ... | 2016 | 27255321 |
