ABSTRACT
The purpose of this work was to investigate the effect of pollination and insects incidence in both quality and quantity of seeds of Pseudotsuga macrolepis available for its natural regeneration in the Western portion of Sierra de Pachuca, state of Hidalgo. Pollination and insects incidence were controlled experimentally. Results appear to indicate that some seeds were developed through parthenogenesis. In addition, ineffective pollination and attack of insects can decrease the amount of potential and produced seeds. Because there are practically no seeds for natural regeneration, we conclude that an artificial repopulation of P. macrolepis is necessary.

    Decomposing coarse woody debris (CWD) is a conspicuous and important component of forest ecosystems. Seasonal temperature and precipitation patterns influence heterotroph activity, which determines the rate of CWD decomposition. We tested the hypothesis that moisture content and heterotroph...

    The article reports that the wasp, Megastigmus spermotrophus, lays its eggs into the cones of Douglas fir trees. It targets the structures that, when fertilised, will become seeds. When Patrick von Aderkas at the University of Victoria, Canada and his colleagues sealed fir cones in bags to...

    Fig trees (Ficus spp.) are pollinated by tiny wasps that enter their enclosed inflorescences (syconia). The wasp larvae also consume some fig ovules, which negatively affects seed production. Within syconia, pollinator larvae mature mostly in the inner ovules whereas seeds develop mostly in...

    Background: Insect pollinator abundance, in particular that of bees, has been shown to be high where there is a superabundance of floral resources; for example in association with mass-flowering crops and also in gardens where flowering plants are often densely planted. Since land management...
