Fig. 3 in Identification guide to Nordic aphids associated with mosses, horsetails and ferns (Bryophyta, Equisetophyta, Polypodiophyta) (Insecta, Hemiptera, Aphidoidea)
Fig. 3. Dioecious one-year holocycle (Rhopalosiphum padi). The inner zone represents the primary host (bird cherry, Prunus padus and allies), the outer zone the secondary (usually graminoids). The fundatrix gives birth to apterae, which in turn give birth to alatae, most of which migrate to the secondary hosts. In autumn males and gynoparae (viviparae giving birth to oviparae) migrate to the primary host, where mating and egg-laying take place. A small fraction of the viviparae may remain on the primary host
Fig. 2 in Identification guide to Nordic aphids associated with mosses, horsetails and ferns (Bryophyta, Equisetophyta, Polypodiophyta) (Insecta, Hemiptera, Aphidoidea)
Fig. 2. Monoecious one-year life cycles. In the outer zone an ordinary monoecious holocycle in Aphididae. The fertilized egg overwinters and in spring the first viviparous parhenogenetic generation, the fundatrix (stem-mother) hatches. Upon the fundatrix follows a variable number of viviparous females (viviparae), apterous and/or alate. In autumn (sometimes earlier) sexuparae are born and in turn give birth to oviparous (sexual) females (ovipara) and males, which mate, and the oviparae lay eggs. The inner zone shows an anholocycle, with only parthenogenetic females (viviparous in Aphididae, oviparous in Adelgidae).
Data from: An update and reassessment of fern and lycophyte diversity data in the Japanese Archipelago
The fern and lycophyte flora of Japan comprising 721 native taxa (including subspecies and varieties) plus 371 combinations of interspecific hybrids was reassessed using a nearly comprehensively sampled distribution map at 10 km resolution vouchered by 216,687 specimens, up-to-date cytotaxonomic information covering 74 % of the taxa, and an rbcL sequence dataset covering 97.9 % of the taxa. Distribution of diversity was visualized by species richness and phylogenetic diversity. Apomixis was observed in 11.0 % of the native taxa whose reproductive modes are known. The number of sexually reproducing polyploid taxa (n = 199) is less than sexual diploids (n = 241), and 30 of them are evidently allopolyploid, in contrast with the low number of possible autopolyploids (n = 4). A morphological character dataset in Lucid format is provided for taxonomic identification of the native taxa.
Goniopteris ×tico (Thelypteridaceae), a new hybrid fern from Costa Rica
<p><em>Goniopteris</em> ×<em>tico</em>, a new hybrid fern from La Selva Biological Station in Heredia Province, Costa Rica, is described based on morphology and analysis of target-capture DNA sequence data. The hybrid co-occurs with its two putative progenitors, <em>Goniopteris</em> <em>mollis</em> and <em>Goniopteris</em> <em>nicaraguensis</em>, and is readily recognizable by its intermediate leaf dissection and venation. It is also intermediate in pinnae size and shape and presents irregularly lobed pinnae. Despite the broad overlap in the geographic distribution of its parental taxa, <em>Goniopteris</em> ×<em>tico</em> is only known from two collections from a single area of the La Selva Biological Station, highlighting the importance of close observation of ferns from even well-collected areas.</p>

Plant–insect interactions from the mid-Cretaceous at Puy-Puy (Aquitaine Basin, western France) indicates preferential herbivory for angiosperms amid a forest of ferns, gymnosperms, and angiosperms
<p>The nine in-text figures and table below (Appendices S1–S10), and the additional text and excel files attached, provide the raw data, summaries of the raw data, rarefaction analyses, and nonmetric multidimensional scale analyses (NMDS) that support the discussions of the main text. The raw data and their summaries of provide for each plant species or morphotype values important for assessment of their herbivory: percentage of specimens herbivorized, damage type (DT) richness, DT frequency, DT host-plant specificity, herbivorized surface area as a proportion of total surface area, and feeding event occurrences. The rarefaction analyses furnished evaluations of whether the number of samples was sufficient, given the surface area covered by those samples. For comparison, the number of samples was rarified to the number of DTs in those samples. Lastly, two NMDS analyses produced the relationships between the plant orders present in the plant assemblage and their interactive functional feeding groups (FFGs). A separate NMDS analysis shows the association between the three most herbivorized species and their FFGs.</p>
