Anticancer and Antioxidant Activities of Rhizospheric Soil Bacteria of <i>Lophocereus marginatus</i>. [PDF]

Int J Microbiol
Identification of new sources of compounds with anticancer and antioxidant potential is essential for cancer treatment. Rhizospheric bacteria have emerged as a promising source of these agents. This study is aimed at investigating the anticancer and antioxidant properties of bacteria isolated from the rhizosphere of Lophocereus marginatus.

Living Away From Specialized Pollinators: The Pollination System of Cieba Pentandra in the Yucatan Peninsula. [PDF]

Ecol Evol
The pollination system of C. pentandra was addressed. This system was highly generalized. ABSTRACT Plant‐pollinator systems can exist along the gradient from extreme specialization to extreme generalization. Theoretical work predicts that high pollinator reliability may lead to specialized pollination systems, while pollinator unpredictability may ...

Establishment patterns of saguaro cactus (Carnegiea gigantea) at the microsite scale help explain saguaro regeneration and distributions in heterogenous, regional habitats. [PDF]

Am J Bot
Abstract Premise Establishment of long‐lived perennial plants is a pivotal event that often leads to reproductive maturity. The population dynamics of the giant saguaro cactus (Carnegiea gigantea) have been investigated over large spatial areas, but establishment patterns have not been studied at the microsite (1 m) scale.

An updated phylogeny and adaptive evolution within Amaranthaceae s.l. inferred from multiple phylogenomic datasets. [PDF]

Ecol Evol
Our results strongly demonstrated that Amaranthaceae s.l. was clustered with monophyletic traditional Chenopodiaceae (Clades I and II) and Amaranthaceae s.s. based on multiple phylogenomic datasets. Phylogenetic analysis of adaptive evolution showed that positively selected genes played a driving role in the evolutionary direction of Amaranthaceae s.l.

Nesting resource availability for cavity adopter birds in a tropical dry forest of Central Mexico

Revista Mexicana de Biodiversidad, 2022
Nesting resources for cavity-adopter birds commonly have spatial aggregation patterns within tropical dry forests. Spatial aggregation occurs because large trees, carrying large cavities, are restricted within small semideciduous forest areas.

Variability in mating strategies in a widespread cactus in the Chihuahuan Desert

Nordic Journal of Botany, Volume 2022, Issue 12, December 2022., 2022
Opuntia is the most diverse and widespread genus in the Cactaceae; several species have broad distribution ranges and have successfully adapted to distinct habitats. One explanation for their success is the diversity of their reproductive systems. Opuntia macrocentra is one of the most common widespread species in North American deserts.

Coalescent‐based species delimitation in North American pinyon pines using low‐copy nuclear genes and plastomes

American Journal of Botany, Volume 109, Issue 5, Page 706-726, May 2022., 2022
Abstract Premise Accurate species delimitation is essential for evolutionary biology, conservation, and biodiversity management. We studied species delimitation in North American pinyon pines, Pinus subsection Cembroides, a natural group with high levels of incomplete lineage sorting.
