“…The differences in LMA can be attributed to LT and density, which constitute the two components that define LMA (Poorter et al, 2009) and can vary independently in ferns (Vasheka et al, 2016). In this sense, HH fronds were both the thickest, mainly due to very thick palisade mesophyll, and the densest (Table 1).…”

Allopolyploidy is a common speciation mechanism in plants; however, its physiological and ecological consequences in niche partitioning have been scarcely studied. In this sense, leaf traits are good proxies to study the adaptive capacity of allopolyploids and diploid parents to their respective environmental conditions. In the present work, leaf water relations (assessed through pressure–volume curves) and structural and anatomical traits of the allotetraploid fern Oeosporangium tinaei and its diploid parents, Oeosporangium hispanicum and Oeosporangium pteridioides, were studied under controlled conditions in response to a water stress (WS) cycle. O. hispanicum showed the lowest osmotic potential at turgor loss point (πtlp) and leaf capacitance, together with higher leaf mass per area (LMA), leaf thickness (LT), leaf density (LD), and leaf dry matter content (LDMC), whereas O. pteridioides presented the opposite set of traits (high πtlp and capacitance, and low LMA, LT, LD, and LDMC). O. tinaei showed an intermediate position for most of the studied traits. The responsiveness (osmotic and elastic adjustments) to WS was low, although most of the traits explained the segregation of the three species across a range of drought tolerance according to the rank: O. hispanicum > O. tinaei > O. pteridioides. These trait differences may underlie the niche segregation among coexisting populations of the three species in the Mediterranean basin.

“…The fronds are dark green, leathery, bare, and intact, which is rare among ferns; their length is 10-60 cm, and their width is 3-6 cm. The petioles are shorter than the frond blade [44,45] (Figure 1 B). On the abaxial surface of the fronds, along the lateral veins, the sori are arranged parallel to each other and covered with two indusia.…”

Asplenium scolopendrium Sporophyte Adapts to Winter Conditions by Changing its Lipid Fatty Acid Composition

Ferns are one of the oldest land plants. Among them, there are species that, during the course of evolution, have adapted to living in temperate climates and under winter conditions. Asplenium scolopendrium is one such species whose fronds are able to tolerate low subzero temperatures in winter. It is known that the resistance of ferns to freezing is associated with their prevention of desiccation via unique properties of the xylem and effective photoprotective mechanisms. In this work, the composition of A. scolopendrium lipid fatty acids (FAs) at different times of the year was studied by gas-liquid chromatography with mass spectrometry to determine their role in the resistance of this species to low temperatures. During the growing season, the polyunsaturated FA content increased significantly. This led to increases in the unsaturation and double-bond indices by winter. In addition, after emergence from snow, medium-chain FAs were found in the fronds. Thus, it can be speculated that the FA composition plays an important role in the adaptation of A. scolopendrium to growing conditions and preparation for successful wintering.

“…En cuanto a los atributos anatómicos, los más estudiados en el género han sido de carácter cualitativo, por ejemplo: la organización del mesofilo de la hoja y la vascularización de los pecíolos y rizomas, teniendo en cuenta el número, forma y configuración de las meristelas (Roux, 2004;Vasheka et al, 2017). Además, los tipos de estomas y los aeróforos, comunes en Dryopteridaceae, pueden aportar información útil para distinguir taxones en Polystichum (Lin & DeVol, 1977, 1978Shah et al, 2018).…”

Introducción y objetivos: Polystichum en Argentina y Chile, comprende 11 especiesoriginadas de los linajes: Sudamericano Austral y Andino. La taxonomía del géneroes conflictiva debido a la frecuente hibridación, asociada a patrones de especiación reticulada. El presente estudio tiene como objetivos: definir caracteres morfo-anatómicos que contribuyan a la diferenciación de los linajes y a la delimitación de nueve de los taxones que comprenden.M&M: Se realizaron mediciones exomorfológicas y análisis de la anatomía defrondes y rizomas de nueve especies de Polystichum (siete del clado AustralSudamericano y dos del Andino), usando microscopía óptica. En las especiesAustrales Sudamericanas se estudiaron 13 caracteres cuantitativos empleando 77especímenes de herbario, mediante análisis multivariados.Resultados: Los caracteres morfológicos que separan el clado SudamericanoAustral de Polystichum de las especies Andinas analizadas, son: los indusios, lasespínulas foliares y el margen de las escamas de rizomas y pecíolos. La formay división de la lámina, el número de pares de pinnas y la cantidad de ellas consoros, la longitud de las pinnas basales y características anatómicas como: pelosglandulares del indusio, banda circumendodermal y número de meristelas del pecíolo, son rasgos informativos a nivel específico del clado Sudamericano Austral.Conclusiones: Por primera vez, una combinación de atributos anatómicos,morfológicos y morfométricos han permitido separar de manera confiable los nueve Polystichum estudiados, demostrando su valor taxonómico.
