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.

1053. Furcraea macdougallii Matuda: Asparagaceae

Curtis's Botanical Magazine, Volume 40, Issue 1, Page 25-34, March 2023., 2023
Summary Furcraea macdougallii Matuda, Falso Maguey Grande, is illustrated (Plate 1053). Its history in cultivation and distribution in Mexico are discussed. Its conservation status: probably extinct in the wild.

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.

Asynchronous flowering patterns in saguaro cacti (Carnegiea gigantea)

Ecosphere, Volume 12, Issue 12, December 2021., 2021
Abstract The saguaro cactus (Carnegiea gigantea [Engelm.] Britton & Rose) is a keystone species endemic to the Sonoran Desert of northern Mexico and the southwestern United States. The saguaro produces large white flowers near its stem apex (crown) during April–June, which bloom at night and close the following day.

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.

Human food use increases plant geographical ranges in the Sonoran Desert

Global Ecology and Biogeography, Volume 30, Issue 7, Page 1461-1473, July 2021., 2021
Abstract Aim Climate is usually regarded as the main determinant of plant species distributions. However, past human use of species for food might also have influenced distributions. We hypothesized that human‐mediated dispersal has resulted in food plants occupying more of their potential geographical range.

Expression of the KNOTTED HOMEOBOX Genes in the Cactaceae Cambial Zone Suggests Their Involvement in Wood Development [PDF]

, 2017
The vascular cambium is a lateral meristem that produces secondary xylem (i.e., wood) and phloem. Different Cactaceae species develop different types of secondary xylem; however, little is known about the mechanisms underlying wood formation in the ...

Widespread male sterility and trioecy in androdioecious Mercurialis annua: Its distribution, genetic basis, and estimates of morph-specific fitness components. [PDF]

Am J Bot
Abstract Premise Angiosperms range in sexual system from hermaphroditism through gynodioecy and androdioecy to dioecy. Trioecy, where females and males coexist with hermaphrodites, is rare. Recently, trioecy was documented in hexaploid populations of the wind‐pollinated herb Mercurialis annua in Spain.
