Thermal Tolerance of Honeybees (Apis mellifera L.) Changes Across an Elevation Gradient in the Mexican Transition Zone

open access: yesSociobiology
The objective of this study was to determine the critical thermal minimum [CTmin], critical thermal maximum [CTmax], and thermal tolerance range of A. mellifera at three different elevations located in the Mexican Transition Zone: 11; 1,324, and 3,304 m ...

Temperature and Precipitation Explain Bee Diversity on Flowers Along an Elevation Gradient in the Mexican Transition Zone

open access: yesSociobiology
Although ecologists have identified the key factors influencing species distribution along elevation gradients, each mountain’s distinct characteristics, including its geology and biotic colonization processes, are often overlooked.

Distribution of Phloeosinus tacubayae Hopkins, 1905 (Curculionidae, Scolytinae), the Cypress Bark Beetle, and new records from potential distribution models [PDF]

open access: yesCheck List, 2022
We evaluated the biotic and abiotic conditions related to the presence of Phloeosinus tacubayae Hopkins, 1905, to update its distribution and explore new areas to collect the species from potential distribution models and establish its host range.

Contributions of Cladistic Biogeography to the Mexican Transition Zone [PDF]

open access: yes, 2012
The Mexican Transition Zone (MTZ) was defined by Halffter (1987) as the complex area where Neotropical and Nearctic biotic elements overlap, including the southern United States, Mexico and adjacent areas of Central America. The biota of this area has received the attention of several naturalists since the mid 19th century (e.g.

A new species of Onthophagus (Scarabaeoidea: Scarabaeinae) from the Mexican Transition Zone, with remarks on its relationships and distribution

open access: yesZootaxa, 2016
A new American Onthophagus of the chevrolati species-group is described (Onthophagus bolivari sp. nov.), providing also identification keys to the aztecus complex. Dorsal habitus and genital structures of the new species are illustrated. The relationships and geographical distribution of the aztecus complex are discussed, giving particular attention to

Track analysis of the funnel-web spiders (Araneae: Agelenidae) of Mexico

open access: yesRevista Mexicana de Biodiversidad, 2018
We analyzed distributional data of 59 species of funnel-web spiders (Araneae: Agelenidae) of Mexico. We constructed individual tracks for the species analyzed, based on published and unpublished records, and based on their overlap we obtained 9 ...

The diversification of Nearctic mammals in the Mexican transition zone [PDF]

open access: yesBiological Journal of the Linnean Society, 2004
The boundary between the Nearctic and Neotropical regions has been delineated using different approaches, methods and taxa. Using a paribiogeographical approach, identification of nodes can help understand the dynamics and evolution of the boundary.

Amphibian areas of endemism: A conservation priority in the threatened Mexican cloud forest [PDF]

open access: yesVertebrate Zoology, 2022
Amphibians of the Mexican Cloud Forest have a great diversity but are highly threatened. Forest endemisms are useful for recognizing biodiversity hotspots; furthermore, the interaction of historical and current events has generated areas of endemism that

Spatial phylogenetics in Hechtioideae (Bromeliaceae) reveals recent diversification and dispersal

open access: yesBotan‪ical Sciences, 2022
Background: Hechtioideae is a group of Bromeliaceae that is distributed in Megamexico III. In recent years, evolutionary relationships within this lineage have been studied, however, the biogeography of these plants have not yet been explored from a ...
