Chemical variations in Quercus pollen as a tool for taxonomic identification: implications for long-term ecological and biogeographical research

Aim Fossil pollen is an important tool for understanding biogeographic patterns in the past, but the taxonomic resolution of the fossil-pollen record may be limited to genus or even family level. Chemical analysis of pollen grains has the potential to increase the taxonomic resolution of pollen, but present-day chemical variability is poorly understood. This study aims to investigate whether a phylogenetic signal is present in the chemical variations of Quercus L. pollen and to assess the prospects of chemical techniques for identification in biogeographic research. Location Portugal Taxon Six taxa (five species, one subspecies) of Quercus L., Q. faginea, Q. robur, Q. robur ssp. estremadurensis, Q. coccifera, Q. rotundifolia and Q. suber belonging to three sections: Cerris, Ilex, and Quercus (<a href="https://www.biorxiv.org/content/10.1101/761148v2#ref-13">Denk, Grimm, Manos, Deng, & Hipp, 2017</a>) Methods We collected pollen samples from 297 individual Quercus trees across a 4° (∼450 km) latitudinal gradient and determined chemical differences using Fourier-transform infrared spectroscopy (FTIR). We used canonical powered partial least-squares regression (CPPLS) and discriminant analysis to describe within- and between-species chemical variability. Results We find clear differences in the FTIR spectra from Quercus pollen at the section level (Cerris: ∼98%; Ilex: ∼100%; Quercus: ∼97%). Successful discrimination is based on spectral signals related to lipids and sporopollenins. However, discrimination of species within individual Quercus sections is more difficult: overall, species recall is ∼76% and species misidentifications within sections lie between 18% and 31% of the test-set. Main Conclusions Our results demonstrate that subgenus level differentiation of Quercus pollen is possible using FTIR methods, with successful classification at the section level. This indicates that operator-independent FTIR approaches can surpass traditional morphological techniques using the light microscope. Our results have implications both for providing new insights into past colonisation pathways of Quercus, and likewise for forecasting future responses to climate change. However, before FTIR techniques can be applied more broadly across palaeoecology and biogeography, our results also highlight a number of research challenges that still need to be addressed, including developing sporopollenin-specific taxonomic discriminators and determining a more complete understanding of the effects of environmental variation on pollen-chemical signatures in Quercus.

Spiny tails and clades: A fully sampled phylogeny of hoplocercine lizards (Iguanidae/Hoplocercinae) and its taxonomic and nomenclatural implications

Hoplocercine lizards (Enyalioides, Morunasaurus, and Hoplocercus) form a clade of ca. 20 currently recognized species. The phylogenetic relationships among hoplocercine lizards, whose members exhibit striking differences in morphology (e.g., spiny vs. non-spiny tails), have not been clearly resolved by previous molecular phylogenetic studies. We generated a considerably larger dataset including 130 new DNA sequences from one mitochondrial and four nuclear loci for all named and two unnamed species of Hoplocercinae. We analyzed the data under concatenated maximum likelihood (RAxML) and Bayesian (MrBayes) as well as summary coalescent (ASTRAL) approaches. While our phylogenetic hypotheses strongly supported the monophyly of Hoplocercinae, neither Enyalioides nor Morunasaurus was supported as monophyletic. Instead, M. groi was inferred with strong support to form a clade with E. heterolepis and E. laticeps. This clade was in turn the sister taxon to other species of Morunasaurus (M. annularis, M. peruvianus). The remaining species of Enyalioides formed a separate clade with a basal split between western (3 species) and eastern (13 species) subclades. Tree topology tests rejected the monophyly of Enyalioides but failed to reject monophyly of Morunasaurus, suggesting that further study is needed to resolve its taxonomic status. Based on our results, we establish the converted clade names Hoplocercinae, Hoplocercus, Enyalioides, and Morunasaurus, as well as the new clade name Zimiamviasaurus.
