Seed bank dynamics in five Panamanian forests
Many tropical pioneer species depend on the presence of highseeddensities inthesoil forsuccessful recruitment following canopy disturbance (Cheke et al. 1979, Dalling & Hubbell 2002, Guevara Sada & Gómez Pompa 1972, Whitmore 1983). However determinants of variation in the composition and abundance of soil seed banks remain poorly understood. Seed bank densities can be affected by rates of seed ...
متن کاملEstimating soil seed bank characteristics in Ponderosa Pine Forests using vegetation and forest-floor data
Soil seed banks are important for vegetation management because they contain propagules of species that may be considered desirable or undesirable for site colonization after management and disturbance events. Knowledge of seed bank size and composition before planning management activities facilitates proactive management by providing early alerts of exotic species presence and of abilities of...
متن کاملDirectly and Indirectly Acting Cholinomimetics
Cholinomimetic drugs can elicit some or all of the effects that acetylcholine (ACh) produces. This class of drugs includes agents that act directly as agonists at cholinoreceptors and agents that act indirectly by inhibiting the enzymatic destruction of endogenous ACh (i.e., cholinesterase inhibitors).The directly acting cholinomimetics can be subdivided into agents that exert their effects pri...
متن کاملRhizopogon spore bank communities within and among California pine forests.
In this study we examine the distribution of Rhizopogon species in spore banks from five California pine forests. Four of the forest sites were discontinuous populations of Pinus muricata and a fifth was a Pinus ponderosa stand in Sierra National Forest. Rhizopogon species were retrieved by bioassaying the soils with pine seedlings followed by isolation of axenic cultures from individual root t...
