Impact of Domestication on Floral Traits and Rewards: A Comparison Between Wild and Domesticated Squash (<i>Cucurbita</i>). [PDF]

Ecol Evol
Plant domestication primarily targets traits of direct human interest, but also indirectly affects other traits. We investigated the effect of domestication on floral traits and floral rewards of species of the genus Cucurbita. Multivariate Principal Component Analysis shows that floral morphological traits differ between domesticated and wild species (

Transplanting naturally regenerated tree seedlings for tropical forest restoration: a case study of Calophyllum brasiliense and Vochysia guatemalensis in Mexico

Restoration Ecology, Volume 31, Issue 8, November 2023., 2023
Plant species produce far more seedlings than those surviving to adulthood. It would seem reasonable to take advantage of that excess production, by relocating seedlings to desired restoration sites. There is, however, little information available on this issue.

Nichima gen. nov. (Alismataceae) based on reproductive structures from the Oligocene‐Miocene of Mexico

American Journal of Botany, Volume 110, Issue 10, October 2023., 2023
Abstract Premise Alismataceae, a sub‐cosmopolitan family with ca. 17 genera and 113 species, is a large group of aquatic plants. Compression/impressions and bioinclusions of reproductive parts in amber support the documentation of the lineage in low‐latitude North America. In Mexico, fossil aquatic plants have been infrequently documented.

Electron density and its reduced density gradient in the study of π–π interactions

International Journal of Quantum Chemistry, Volume 123, Issue 18, September 15, 2023., 2023
The intermolecular electron density extracted from DFT calculation describes correctly the energetic trends in π−π interactions, although the densities are underestimated. Unexpectedly, signλ2ρ, used in the Non‐Covalent Interaction (NCI) method to estimate attraction or repulsion, shows the wrong trend for π−π stacking systems.
