LANDER STEPHEN A. HARRIS DAVID H. BOSHIER Biología Chile landuse Syrphid Gomortega pollination This study was undertaken to discover whether patterns of flower and fruit production for Gomortega keule , an endangered Chilean tree, differ between exotic pine plantation, agricultural and native forest environments. A pilot study was also undertaken to identify the primary pollinators of G. keule . Although similar proportions of G. keule trees flowered in the agricultural and native forest areas, more trees in the agricultural sites produced fruit compared to trees in the native forest sites. Flowering and fruiting of G. keule was extremely rare in the exotic pine plantations. Our data show that G. keule flowers are predominantly visited by syrphid flies in March-April, and that syrphids carry a greater proportion of G. keule pollen than the other insects collected. Native forest and low intensity agricultural systems appear to provide habitat in which syrphids forage and G. keule is able to produce fruit successfully, but exotic pine plantation does not; suggesting that a landscape made up of a mosaic of different landuse types is not necessarily inimical to the continued reproduction of G. keule , but that the combination and types of landuses and intensity of management must be carefully considered. 2009 artículo científico 0716-078X https://www.redalyc.org/articulo.oa?id=369944291007 en http://www.redalyc.org/revista.oa?id=3699 Revista Chilena de Historia Natural application/pdf Sociedad de Biología de Chile Revista Chilena de Historia Natural (Chile) Num.3 Vol.82 |
