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...

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 (−...
Competitive exclusion of the pioneer species and of the climax species are both possible depending on the relative strength of competition. Stable coexistence of both species may also occur; in two cases, a coexistence state is destabilized through a Neimark–Sacker bifurcation, and an attracting ...
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...
In certain species, such as Brassica campestris, the plant is normally self-sterile and can only be cross-pollinated. In self-pollinating species, such as soybeans and cotton, the male and female plants are anatomically juxtaposed. During natural pollination, the male reproductive organs of a gi...
