Variation in ploidy level and phenology can result in large and unexpected differences in demography and climatic sensitivity between closely related ferns.
de Groot GA, Zuidema PA, de Groot H, During HJ. de Groot GA, et al. Am J Bot. 2012 Aug;99(8):1375-87. doi: 10.3732/ajb.1100482. Epub 2012 Aug 1. Am J Bot. 2012. PMID: 22859655 Free article.
We compared the demography and climatic sensitivity of two closely related ferns: the tetraploid Polystichum aculeatum and one of its diploid parents, Polystichum setiferum. ...KEY RESULTS: Projected population growth rate (lambda) was much higher for the tet …

Calorimetric properties of water and triacylglycerols in fern spores relating to storage at cryogenic temperatures.
Ballesteros D, Walters C. Ballesteros D, et al. Cryobiology. 2007 Aug;55(1):1-9. doi: 10.1016/j.cryobiol.2007.03.006. Epub 2007 Apr 14. Cryobiology. 2007. PMID: 17553480
We used differential scanning calorimetry (DSC) to monitor enthalpy and temperature of water and TAG phase transitions within spores of five fern species: Pteris vittata, Thelypteris palustris, Dryopteris filix-mas, Polystichum aculeatum, Polystichum setiferu …

Diverse spore rains and limited local exchange shape fern genetic diversity in a recently created habitat colonized by long-distance dispersal.
De Groot GA, During HJ, Ansell SW, Schneider H, Bremer P, Wubs ER, Maas JW, Korpelainen H, Erkens RH. De Groot GA, et al. Ann Bot. 2012 Apr;109(5):965-78. doi: 10.1093/aob/mcs013. Epub 2012 Feb 9. Ann Bot. 2012. PMID: 22323427 Free PMC article.
METHODS: Microsatellite markers were used to analyse the amount and distribution of genetic diversity in young populations of four widespread calcicole ferns (Asplenium scolopendrium, diploid; Asplenium trichomanes subsp. quadrivalens, tetraploid; Polystichum setiferum, di …

Inter-and intraspecific variation in fern mating systems after long-distance colonization: the importance of selfing.
de Groot GA, Verduyn B, Wubs ER, Erkens RH, During HJ. de Groot GA, et al. BMC Plant Biol. 2012 Jan 4;12:3. doi: 10.1186/1471-2229-12-3. BMC Plant Biol. 2012. PMID: 22217252 Free PMC article.
RESULTS: We examined intra-and interspecific variation in potential for self-fertilization among four rare fern species, of which two were diploids and two were tetraploids: Asplenium scolopendrium (2n), Asplenium trichomanes subsp. quadrivalens (4n), Polystichum setiferum …
