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>
TWO DRAFT GENOMES OF FUNGAL leaf endophytes from tropical gymnosperms
<p>Two ascomycetes, <em>Neofusiccocum sp. </em>Z2 and<em> Xylaria sp. </em>Z50<em>, </em>were isolated from healthy leaves of the tropical gymnosperms <em>Zamia pseudoparasitica</em> (Z2) and <em>Z. nana</em> (Z50) from Panama. The two draft genomes possess a broad repertoire of predicted carbohydrate degrading CAZymes, peptidases, secondary metabolites with more secondary metabolite clusters in the <em>Xylaria</em> isolate.</p>

The global distribution and drivers of wood density across angiosperms and gymnosperms and their impact on forest carbon stocks
<p>Abstract:</p> <div>The density of wood is a key indicator of trees’ carbon investment strategies, impacting productivity and carbon storage. Despite its importance, the global variation in wood density and its environmental controls remain poorly understood, preventing accurate predictions of global forest carbon stocks. Here, we analyze information from 1.1 million forest inventory plots alongside wood density data from 10,703 tree species to create a spatially-explicit understanding of the global wood density distribution and its drivers. Our findings reveal a pronounced latitudinal gradient, with wood in tropical forests being up to ~30% denser than that in boreal forests. In both angiosperms and gymnosperms, hydrothermal conditions represented by annual mean temperature and soil moisture emerged as the primary factors influencing the variation in wood density globally. This indicates similar environmental filters and evolutionary adaptations among distinct plant groups, underscoring the essential role of abiotic factors in determining wood density in forest ecosystems. Additionally, our study highlights the prominent role of disturbance, such as human modification and fire risk, in influencing wood density at more local scales. Factoring in the spatial variation of wood density notably changes the estimates of forest carbon stocks, leading to differences of up to 21% within biomes. Therefore, our research contributes to a deeper understanding of terrestrial biomass distribution and how environmental changes and disturbances impact forest ecosystems.</div> <div> </div> <p>This repository only provides the tif data of this paper.
