“…Although several studies show niche divergence between allopolyploids and at least one of their progenitors (Glennon et al., , ; Theodoridis et al., ; Harbert et al., ; Han et al., ; López‐Alvarez et al., ; Marchant et al., ), other studies show allopolyploid lineages have intermediate or non‐divergent ecological niches (Oberprieler et al., ; Glennon et al., ; Harbert et al., ; Boucher et al., ; Marchant et al., ; Casazza et al., ). For autopolyploids, some studies have found significant ecological segregation between polyploids and their ancestors (Schönswetter et al., ; Stahlberg, ; Thompson et al., ; Hülber et al., ; Zozomová‐Lihová et al., ; Lazaroff et al., ; Mandák et al., ; Mered'a et al., ; Sonnleitner et al., ; Visger et al., ), and yet other studies find no ecological divergence between cytotypes (Godsoe et al., ; Hanzl et al., ). Most of the reported studies are limited to evaluating if niches are conserved but do not investigate how the niches of the two cytotypes differ in aspects such as optima and breadths (but see Kirchheimer et al., ).…”
