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...
2. One who opens up new areas of thought, research, or development: a pioneer in aviation. 3. A soldier who performs construction and demolition work in the field to facilitate troop movements. 4. A species that is typically among the first to become established in a bare, open, or dist...

Each population is subject to inter- and intraspecific competition; population growth is dependent on the combined densities of both species. Nine different geometric cases, corresponding to different orientations of the zero-growth isoclines, are possible for this system. We fully characterize the ...
There are a small number of weed species, however, for which resistance to multiple herbicides now leaves growers with few viable options for control (Table 1). Multiple Herbicide Resistance - Definition Resistance to several herbicides resulting from two or more distinct resistance mechanisms ...
Biomorphology, metric characters, and seed germination have been studied in 17 pioneer plant species overgrowing friable erupted materials in the Kamchatka Peninsula. The diversity of pathways of adaptation to stressful growing conditions is discussed. The response of seeds to ultralow temperature (−...
Here we have determined high-resolution structures of three FoxH1 proteins (from human, frog and fish species) and four DNAs to clarify the way in which FoxH1 binds to these sites. We found that the protein-DNA interactions extend to both the minor and major DNA grooves and are thus ...
Of course, we cannot turn back [the clock] on the loss of species. That’s a finite, terminal loss, which is really damaging. But [for the] functions of ecosystems, it’s not too late to now turn back and move towards a safe space and build resilience into both food systems and ec...
