Status and Distribution of Chihuahuan Desert Grasslands in the United States and Mexico Grasslands comprise a small part of the Chihuahuan Desert but are vital to the biological diversity of the ecoregion. Characteristic grasses of the Chihuahuan Desert are tobosa (Pleuraphis mutica) and black grama (Bouteloua eriopoda) but other common species include alakali sacaton (Sporobolus airoides), big alkali sacaton (S. wrightii), mesa dropseed (S. flexuosus), blue grama (B. gracilis), sideoats grama (B. curtipendula ), hairy grama (B. hirsuta), slender grama (B. filiformis), chino grama (B. brevista), spruce top grama (B. chondrosioides), bush muhly (Muhlenbergia porteri), several three awns (Aristida spp.), and fluff grass (Dasyochloa pulchela) (Johnson 1974, Dinerstein et al. 2000). Many of the sites discussed...

One hundred people were surveyed amongst livestock producers (both from private ranches and from communal ejidos), and students and researchers at regional institutions involved in agricultural sciences in different states of Mexico: Coahuila, Durango, San Luis Potosí, and Jalisco. The objective of the survey was to determine aspects of stakeholders’ interpretation of the condition of grasslands in their region under conditions of extensive grazing, such as soil condition, harvest efficiency, vegetation condition, openness to community organizing of grazing, capacity...

Sevilleta LTER research includes studies in desert grassland and shrubland communities, and riparian and mountain forests emphasizing pulse driven processes in space and time. Key drivers (e.g., climate, fire, water, resource availability) govern dynamics in each landscape component. Our focus on how biotic and abiotic drivers affect spatial and temporal dynamics of aridland ecosystems allows us to conduct long-term research that addresses important basic theories and yet has significant relevance to regional, national and international priorities.

Dada la importancia del tema, el Instituto Nacional de Ecología, como parte de su misión de generar y difundir información científica y técnica sobre problemas ambientales prioritarios solicitó a un grupo de especialistas de diversas disciplinas que contribuyeran a este libro aportando y compartiendo sus conocimientos y experiencias sobre los aspectos científicos, sociales, económicos e institucionales del cambio climático....

Se ejerce actualmente en México, una elevada presión de uso de los recursos naturales de estas...

To address this need, researchers will use climate model data to predict and map future changes in fire frequency for Texas, Oklahoma, and New Mexico. Researchers will then examine species and ecosystem distribution data to understand the relationship between climate, fire frequency, and species occurrence. This analysis will enable researchers to identify potential future distributions of woody ecosystems and species such...

IRMA (Integrated Resource Management Applications) is the name given to the project that has guided this transformation, and to the web portal that is its end result. View or download the IRMA project brief (.pdf). IRMA is a portfolio of tools and applications, and the beginnings of a "one-stop" for data and information on park-related resources. From IRMA you can search for, view, and download documents, reports, publications, data sets, and park species lists. You can get information on park visitor numbers, park projects, and apply for a park research permit. Park staff can navigate to certain internal...
