Wide ranges of functional traits in the flora from the central region of Sonora: A diversity to be explored

Publications Posted on: September 16, 2013
Although the Sonoran Desert does not have the highest plant species richness, it has been documented with the highest growth form diversity from the North American deserts. It is not known if this high growth form diversity could also harbor a high functional diversity.

Ecosystems and diversity of the Sierra Madre Occidental

Publications Posted on: September 16, 2013
The Sierra Madre Occidental (SMO) is the largest continuous ignimbrite plate on Earth. Despite its high biological and cultural diversity and enormous environmental and economical importance, it is yet not well known. We describe the vegetation and present a preliminary regionalization based on physiographic, climatic, and floristic criteria.

Biogeography and diversity of pines in the Madrean Archipelago

Publications Posted on: September 16, 2013
Pines are important dominants in pine-oak, pine and mixed-conifer forests across the Colorado Plateau, southern Rocky Mountains, Sierra Madre Occidental, and in the intervening Sky Islands of the United States-Mexico borderlands. All 17 native species of pines in the Sky Islands region or their adjacent mountain mainlands reach the northern or southern margins of their geographic ranges and most (12) have Madrean vs. Petran affinities.

Preliminary assessment of species richness and avian community dynamics in the Madrean Sky Islands, Arizona

Publications Posted on: September 16, 2013
The Sky Island mountain ranges of southeastern Arizona contain a unique and rich avifaunal community, including many Neotropical migratory species whose northern breeding range extends to these mountains along with many species typical of similar habitats throughout western North America.

Bird list of San Bernardino Ranch in Agua Prieta, Sonora, Mexico

Publications Posted on: September 16, 2013
Interest and investigation of birds has been increasing over the last decades due to the loss of their habitats, and declination and fragmentation of their populations. San Bernardino Ranch is located in the desert grassland region of northeastern Sonora, México. Over the last decade, restoration efforts have tried to address the effects of long deteriorating economic activities, like agriculture and livestock, that used to take place there.

Sand dune of Ruby, Arizona, an anthropogenically created biodiversity hotspot for wasps and their velvet ant parasitoids

Publications Posted on: September 16, 2013
A large artificial sand dune composed of finely crushed mine tailings was produced by deep mining operations at Ruby, Arizona. Today, the ghost town of Ruby is an important historical location and biodiversity refuge, with the newly formed dune forming the core of the refuge.

Preliminary assessment of the moth (Lepidoptera: Heterocera) fauna of Rincon de Guadalupe, Sierra de Bacadehuachi, Sonora, Mexico

Publications Posted on: September 16, 2013
The Sierra de Bacadéhuachi is a poorly sampled extension of the Sierra Madre Occidental (SMO) located in east-central Sonora near the town of Bacadéhuachi. Sampling of moths using mercury vapor and ultraviolet lights occurred in summer and fall 2011, and spring 2012 at Rincón de Guadalupe, located in pine-oak forest at 1680 m elevation. Approximately 400 taxa of moths were identified from this locality.

Introduction to the Arizona Sky Island Arthropod Project (ASAP): Systematics, biogeography, ecology, and population genetics of arthropods of the Madrean Sky Islands

Publications Posted on: September 16, 2013
The Arizona Sky Island Arthropod Project (ASAP) is a new multi-disciplinary research program at the University of Arizona that combines systematics, biogeography, ecology, and population genetics to study origins and patterns of arthropod diversity along elevation gradients and among mountain ranges in the Madrean Sky Island Region.

Preliminary survey of bee (Hymenoptera: Anthophila) richness in the northwestern Chihuahuan Desert

Publications Posted on: September 16, 2013
Museum records indicate that the peak number of bee species occurs around the Mediterranean Sea and in the warm desert areas of North America, whereas flowering plants are most diverse in the tropics. We examine this biogeographic pattern for the bee species known from a limited area of northeastern Chihuahuan Desert, Mexico/United States.

Preliminary assessment of biogeographic affinities of selected insect taxa of the state of Sonora, Mexico

Publications Posted on: September 16, 2013
The biogeographic affinites of butterflies (Lepidoptera: Papilionoidea and Hesperidae), damsel and dragonflies (Odonata), and ants (Hymenoptera: Formicidae) reported from the State of Sonora, Mexico were analyzed using published species lists.
