Morpho-anatomical Studies and Evolutionary Interpretations of the Rhizomes of Extant Dennstaedtiaceae [PDF]

open access: yesAmerican Fern Journal, 2017
Dennstaedtiaceae is a monophyletic, extant family of ferns with sub-cosmopolitan distribution and ca. 265 species. Rhizome morphology in the Dennstaedtiaceae is relatively well known, yet its anatomy has been poorly explored. We performed morpho-anatomical studies on 26 taxa from eight genera, mostly from Brazil, Japan, and New Zealand.

Native herbivore browsing alters plant physical and chemical traits in a eucalypt forest understory

open access: yesEcosphere, Volume 15, Issue 1, January 2024.
Abstract Macropods exhibit selective herbivory on plant traits within and between species and hence can alter plant trait variation. In this study, we asked what are the effects of macropod herbivory on intraspecific variation in plant traits of forest understory species?
