The distinction between pioneer and nonpioneer life histories is difficult to delineate as traits such as growth or mortality rate, or shade-tolerance vary continuously among species. Nonetheless, a life-history tradeoff determined by growth in high light and survival in the shade limits the habitat...
Biology definition:Pioneer speciesis the first ones to colonize a bare substrate in primary succession while first to colonize a destroyed habitat in secondary succession.Examples:(1) a pioneer species of lyme grass (Leymus arenarius) on a barren land of sand, (2) pioneer species ofplants(e.g...

another. In some cases, more than one species can be a pioneer species. Sometimes, a group of species inhabits a barren area at the same time. When this occurs, apioneer communityis created. A pioneer community relies on one another as they learn to live and interact in this new area....

A pioneer–climax species model with migration is presented. It is shown that the system can present a variety of configurations which represent competitive exclusion scenarios and coexistence scenarios, including coexistence under sustained oscillation scenarios. We analyze all the possible configurations ...
Many rare plant species occur in Dutch wet dune slacks, particularly in the Junco baltici-Schoenetum nigricantis. For nature management it is important to understand the processes controlling the presence of these basiphilous early succe... Karle V. Sýkora,Jeroen C.J.M. van den Bogert,F...
