The Relationships of the Euphorbieae (Euphorbiaceae)

open access: yesAnnals of the Missouri Botanical Garden, 1994
The Euphorbieae and Hippomaneae, though both usually placed in subfamily Euphorbioideae, differ in many inflorescence details and can be linked unambiguously only by one cryptic character: the rod-shaped starch grains in the latex. While the Hippomaneae have inflorescences very similar to those of many other members of the Euphorbiaceae, the ...

A survey of selected coastal vegetation communities of Florida [PDF]

open access: yes, 1977
A survey of coastal vegetation around Florida was conducted during 1973 and 1974. Seventeen sites were selected and sampled using the transect method to determine species occurrence, relative densities, and habitat development and structure.

Variation in root hair traits in 75 xerophytic species: Constraints of phylogeny, trait trade‐offs and environment

open access: yesFunctional Ecology, Volume 39, Issue 6, Page 1594-1605, June 2025.
Abstract Root hairs play an important role in the acquisition of soil resources by increasing the absorptive surface area. Yet, key factors driving the variation of root hair traits across different species along biogeographic gradients are still poorly quantified, limiting our understanding of the functional relevance of root hairs.

Across 33 broad‐leaved deciduous woody species, silicon enhances leaf lamina stiffness but not tensile strength whereas cellulose enhances both

open access: yesNew Phytologist, Volume 246, Issue 5, Page 2075-2083, June 2025.
Summary Silicon (Si) has been hypothesized to be a metabolically cheaper substitute for carbon‐based cell wall components to support leaves. However, how the biomechanical function of Si, deposited as amorphous silica, differs from cell wall components remains untested. Here, we tested the hypothesis that species with higher leaf Si concentrations have

Germination responses of a dry sclerophyll forest soil-stored seedbank to fire related cues [PDF]

open access: yes, 2013
Fire is an integral component of many ecosystems worldwide. Many plant species require fire-related cues, primarily heat and smoke, to trigger germination. Despite the importance of this process, the responses of many Australian species to these cues are

Mexican Lepidoptera biodiversity [PDF]

open access: yes, 2002
Being among the most habitat diverse countries in the world (and plant diversity is about 22,000 sp.), Mexico has a Lepidoptera fauna recorded at about 14,385 species but is estimated to be over 22,000 species, if not much higher (some estimates go to 35,
