Cones and consequences: the false dichotomy of conifers vs broad-leaves has critical implications for research and modelling. [PDF]
New PhytolSummary In plant science research and modelling, particularly from the northern hemisphere, the terms ‘needle‐leaved’ and ‘conifer’ along with ‘broad‐leaved’ and ‘angiosperm’ are often used synonymously, creating the false dichotomy that conifers are needle‐leaved and angiosperms are broad‐leaved.

Chemical ecology of symbioses in cycads, an ancient plant lineage. [PDF]
New PhytolSummary Cycads are an ancient lineage of gymnosperms that maintain a plethora of symbiotic associations from across the tree of life. They have myriad morphological, structural, physiological, chemical, and behavioral adaptations that position them as a unique system to study the evolution, ecology, and mechanism of symbiosis.
