Anthropogenic landscape changes and avian diversity at Los Tuxtlas, Mexico
Biodiversity & Conservation, 1997Faced with rapid and extensive conversion of tropical rain forests to a landscape consisting of pasture lands, and with the need to preserve the avian diversity of tropical regions, it is imperative to determine how different species have responded to anthropogenic alterations of their natural habitats.

Geochemistry, petrogenesis, and tectonic setting of the Los Tuxtlas Volcanic Field, Mexico
Geological Journal, 2020We present new major and trace element geochemical data, including the rare‐earth elements (REE), platinum group elements and Au, and combine them with the published information to constrain the highly debated origin of magmas in the Los Tuxtlas Volcanic Field (LTVF) of the Late Miocene to historic age.

Rates of Deforestation in Los Tuxtlas, a Neotropical Area in Southeast Mexico
Conservation Biology, 1992Abstract: On the basis of ground surveys, aerial photographs (for 1967 and 1976), and satellite imagery (for 1986), maps of rain forest distribution were developed for the northern part of the Sierra de Los Tuxtlas (Veracruz, southeast Mexico).

Glomeromycota associated with Mexican native maize landraces in Los Tuxtlas, Mexico
Applied Soil Ecology, 2015Abstract Many native maize landraces are still cultivated by different ethnic groups in Mexico as part of traditional polyculture systems (milpas). However, these systems and landraces are being steadily replaced by fertilized monocultures of genetically improved varieties or maize hybrids.

Formative Period Settlement Patterns in the Sierra de los Tuxtlas
Abstract The Sierra de los Tuxtlas, located in Southern Veracruz, Mexico, exhibits a pre-Columbian sequence that includes a substantial Formative Period (ca. 2000 cal BC–cal AD 300) presence. In fact, studies of ancient settlements in and immediately around the Tuxtlas provided an initial impetus for investigations that came to ...Lourdes Budar, Philip J. Arnold

Lessons from Los Tuxtlas: 30 Years of Research into Primates in Fragments
2013The region of Los Tuxtlas in the state of Veracruz, southeast Mexico, represents the northernmost limit of tropical rainforest in the Americas and is home to populations of two primate species, the Mexican howler monkey (Alouatta palliata mexicana) and the Mexican spider monkey (Ateles geoffroyi vellerosus).

Structure and floristic composition of the lowland rain forest of Los Tuxtlas, Mexico
Vegetatio, 1988Physiognomy, structure and floristic composition of one hectare of lowland tropical rain forest was studied in detail at Los Tuxtlas, Mexico. Physiognomically, the Los Tuxtlas forest should be classified as ‘lowland tropical high evergreen rain forest’. The forest showed a closed canopy at 30–35 m.

Journal of Parasitology, 2004
A total of 76 adult individuals of Rana vaillanti were collected in Laguna Escondida, Los Tuxtlas, Veracruz, Mexico, and their helminth infracommunity structure was determined. Among the 21 helminth taxa collected (10 digeneans, 8 nematodes, and 3 acanthocephalans), the digenean Langeronia macrocirra reached the highest prevalence (64.4%), mean ...

Native bradyrhizobia from Los Tuxtlas in Mexico are symbionts of Phaseolus lunatus (Lima bean)
Systematic and Applied Microbiology, 2013Los Tuxtlas is the northernmost rain forest in North America and is rich in Bradyrhizobium with an unprecedented number of novel lineages. ITS sequence analysis of legumes in polycultures from Los Tuxtlas led to the identification of Phaseolus lunatus and Vigna unguiculata in addition to Phaseolus vulgaris as legumes associated with maize in crops ...

Seed rain from forest fragments into tropical pastures in Los Tuxtlas, Mexico
Plant Ecology, 1999Deforestation has resulted in the fragmentation of forests. Remnant fragments are widely assumed to be sources of seeds for forest regeneration in abandoned pastures. The seed rain in 12 pastures at Los Tuxtlas, Mexico, their relationship with riparian vegetation adjacent to them, and their closeness to the reserve is described.
