S Heiser, CD Amsler, S Stoeckel… - Journal of …, 2023‏ - Wiley Online Library
Meiosis and syngamy generate an alternation between two ploidy stages, but the timing of
these two processes varies widely across taxa, thereby generating life cycle diversity. One …

founder effects and enhanced tolerance towards environmental stresses. However, the …

Stable demographic ratios of haploid gametophyte to diploid sporophyte abundance in macroalgal populations

K Bessho - Plos one, 2024‏ - journals.plos.org
Macroalgal populations often consist of free-living haploid (gametophyte) and diploid
(sporophyte) stages. Various ecological studies have been conducted to examine the …
