Última Seedling recruitment of Austrocedrus chilensis in relation to cattle use, microsite environment and forest disease Ecología austral La Manna,Ludmila; Collantes,Marta; Bava,José; Rajchenberg,Mario. The forests of Austrocedrus chilensis in the Patagonian Andes suffer a disease known as "mal del ciprés". The purpose of this work was to identify the relationship between A. chilensis seedling recruitment and disturbances (i.e., disease and cattle grazing), and to identify associations between seedling recruitment and microsite characteristics related to the disturbances. Eighteen sites with "mal del ciprés" were selected for study. In each site, symptomatic and asymptomatic plots were established and characterized. Five control sites, where the disease was totally absent, were also included. Cattle use and disease were negatively associated with A. chilensis natural regeneration. Both disturbances seemed to act synergically. In control sites the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Forest decline; Mal del ciprés; Natural regeneration; Site effect.

We compile and analyze a dataset of secondary microseismic P-wave spectra that were observed by North American seismic arrays. Two distinct frequency bands, 0.13–0.15Hz and 0.19–0.21Hz, with enhanced P-wave energy characterize the dataset. Cluster analysis allows to classify the spectra and to associate typical spectral shapes with geographical regions: Low frequency dominated spectra (0.13-0.15Hz) are mostly detected in shallower regions of the North Atlantic and the South Pacific, as well as along the Central and South American Pacific coast. High frequency dominated spectra (0.19-0.21Hz) are mostly detected in deeper regions of the North-Western Pacific and the South Pacific. For a selected subset of high quality sources, we compute synthetic spectra... Tipo: Text Palavras-chave: Secondary microseisms; Body waves; Noise source spectra; Ocean waves; Site effect.
