Litter of woody species of NW Patagonian shrublands: composition, structure and heterogeneity. Litter is an important component of ecosystems. It influences nutrient dynamics and microsite conditions (e.g., solar radiation, soil temperature and water retention). Consequently, litter could affect plant regeneration, either positively or negatively. Our aim was to study abundance, composition, heterogeneity and annual production of the litter produced by fifteen common woody species in shrublands of NW Patagonia. Total litter varied from 347.9 to 2534.7 gm-2. Litter accumulation in these shrublands was lower than in Andean forests but similar to other shrublands of other regions. Also, annual production of litter was lower than in other ecosystems and similar to the Patagonian Monte. Litter heterogeneity was similar among species. Perennial species accumulated and produced more litter per year than deciduous species. These results could be important to understand the regeneration process and nutrient cycling at the community scale. In both functional groups we found some species with extreme values in most variables and others which intermediate values which represent a variation gradient. This provides this system with a high diversity of microsites associated with litter El mantillo es un componente importante de los ecosistemas, que afecta tanto la dinámica de nutrientes como las condiciones de micrositio (e.g., radiación, temperatura y retención de humedad del suelo) y, en consecuencia, puede tener diferentes tipos de efectos sobre la regeneración de las especies. El objetivo de este trabajo fue estudiar, bajo el dosel de 15 especies leñosas, muy frecuentes en los matorrales del NO de la Patagonia, la abundancia, composición, estructura y heterogeneidad del mantillo y la producción de material senescente/año. El mantillo total acumulado varió entre 347,9 y 2534,7 gm-2. El mantillo y la producción de material senescente/año fue baja comparada con otros ecosistemas y similar a la del monte Patagónico. La heterogeneidad del mantillo fue similar entre la mayoría de las especies. Las especies perennifolias tuvieron mayor acumulación de mantillo y producción de material senescente por año que las especies caducifolias. Esto podría tener implicancias en la regeneración y ciclado de nutrientes a escala de comunidad. En ambos grupos funcionales se encontraron especies con valores extremos y otras que representan un gradiente de variación. Esto contribuye a darle a este sistema una alta diversidad de micrositios asociada al mantillo Sociedad Argentina de Botánica 2014-06-30 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículo original application/pdf https://revistas.unc.edu.ar/index.php/BSAB/article/view/7607 10.31055/1851.2372.v48.n3-4.7607 Boletín de la Sociedad Argentina de Botánica (Journal of the Argentine Botanical Society; Vol. 48 No. 3-4 (2013): Diciembre; 525-541 Boletín de la Sociedad Argentina de Botánica; Vol. 48 Núm. 3-4 (2013): Diciembre; 525-541 Boletín de la Sociedad Argentina de Botánica; v. 48 n. 3-4 (2013): Diciembre; 525-541 1851-2372 0373-580X 10.31055/1851.2372.v48.n3-4 spa https://revistas.unc.edu.ar/index.php/BSAB/article/view/7607/8574 |
