A Vegetation Map of Carlsbad Caverns National Park, New Mexico 1
______________________________________________________________________________ A Vegetation Map of Carlsbad Caverns National Park, New Mexico ______________________________________________________________________________ 2003 A Vegetation Map of Carlsbad Caverns National Park, New Mexico 1 Esteban Muldavin, Paul Neville, Paul Arbetan, Yvonne Chauvin, Amanda Browder, and Teri Neville2 ABSTRACT A vegetation classification and high resolution vegetation map was developed for Carlsbad Caverns National Park, New Mexico to support natural resources management, particularly fire management and rare species habitat analysis. The classification and map were based on 400 field plots collected between 1999 and 2002. The vegetation communities of Carlsbad Caverns NP are diverse. They range from desert shrublands and semi-grasslands of the lowland basins and foothills up through montane grasslands, shrublands, and woodlands of the highest elevations. Using various multivariate statistical tools, we identified 85 plant associations for the park, many of them unique in the Southwest. The vegetation map was developed using a combination of automated digital processing (supervised classifications) and direct image interpretation of high-resolution satellite imagery (Landsat Thematic Mapper and IKONOS). The map is composed of 34 map units derived from the vegetation classification, and is designed to facilitate ecologically based natural resources management at a 1:24,000 scale with 0.5 ha minimum map unit size (NPS national standard). Along with an overview of the vegetation ecology of the park in the context of the classification, descriptions of the composition and distribution of each map unit are provided. The map was delivered both in hard copy and in digital form as part of a geographic information system (GIS) compatible with that used in the park. -
Native Trees of Mexico: Diversity, Distribution, Uses and Conservation

ABSTRACT Background. Mexico is one of the most floristically rich countries in the world. Despite significant contributions made on the understanding of its unique flora, the knowledge on its diversity, geographic distribution and human uses, is still largely fragmented. Unfortunately, deforestation is heavily impacting this country and native tree species are under threat. The loss of trees has a direct impact on vital ecosystem services, affecting the natural capital of Mexico and people's livelihoods. Given the importance of trees in Mexico for many aspects of human well-being, it is critical to have a more complete understanding of their diversity, distribution, traditional uses and conservation status. We aimed to produce the most comprehensive database and catalogue on native trees of Mexico by filling those gaps, to support their in situ and ex situ conservation, promote their sustainable use, and inform reforestation and livelihoods programmes. Methods. A database with all the tree species reported for Mexico was prepared by compiling information from herbaria and reviewing the available floras. Species names were reconciled and various specialised sources were used to extract additional species information, i.e. -

Grasses of the Texas Hill Country: Vegetative Key and Descriptions
Hagenbuch, K.W. and D.E. Lemke. 2015. Grasses of the Texas Hill Country: Vegetative key and descriptions. Phytoneuron 2015-4: 1–93. Published 7 January 2015. ISSN 2153 733X GRASSES OF THE TEXAS HILL COUNTRY: VEGETATIVE KEY AND DESCRIPTIONS KARL W. HAGENBUCH Department of Biological Sciences San Antonio College 1300 San Pedro Avenue San Antonio, Texas 78212-4299 [email protected] DAVID E. LEMKE Department of Biology Texas State University 601 University Drive San Marcos, Texas 78666-4684 [email protected] ABSTRACT A key and a set of descriptions, based solely on vegetative characteristics, is provided for the identification of 66 genera and 160 grass species, both native and naturalized, of the Texas Hill Country. The principal characters used (features of longevity, growth form, roots, rhizomes and stolons, culms, leaf sheaths, collars, auricles, ligules, leaf blades, vernation, vestiture, and habitat) are discussed and illustrated. This treatment should prove useful at times when reproductive material is not available. Because of its size and variation in environmental conditions, Texas provides habitat for well over 700 species of grasses (Shaw 2012). For identification purposes, the works of Correll and Johnston (1970); Gould (1975) and, more recently, Shaw (2012) treat Texas grasses in their entirety. In addition to these comprehensive works, regional taxonomic treatments have been done for the grasses of the Cross Timbers and Prairies (Hignight et al. 1988), the South Texas Brush Country (Lonard 1993; Everitt et al. 2011), the Gulf Prairies and Marshes (Hatch et al. 1999), and the Trans-Pecos (Powell 1994) natural regions. In these, as well as in numerous other manuals and keys, accurate identification of grass species depends on the availability of reproductive material. -

An Updated Infrageneric Classification of the North American Oaks
Article An Updated Infrageneric Classification of the North American Oaks (Quercus Subgenus Quercus): Review of the Contribution of Phylogenomic Data to Biogeography and Species Diversity Paul S. Manos 1,* and Andrew L. Hipp 2 1 Department of Biology, Duke University, 330 Bio Sci Bldg, Durham, NC 27708, USA 2 The Morton Arboretum, Center for Tree Science, 4100 Illinois 53, Lisle, IL 60532, USA; [email protected] * Correspondence: [email protected] Abstract: The oak flora of North America north of Mexico is both phylogenetically diverse and species-rich, including 92 species placed in five sections of subgenus Quercus, the oak clade centered on the Americas. Despite phylogenetic and taxonomic progress on the genus over the past 45 years, classification of species at the subsectional level remains unchanged since the early treatments by WL Trelease, AA Camus, and CH Muller. In recent work, we used a RAD-seq based phylogeny including 250 species sampled from throughout the Americas and Eurasia to reconstruct the timing and biogeography of the North American oak radiation. This work demonstrates that the North American oak flora comprises mostly regional species radiations with limited phylogenetic affinities to Mexican clades, and two sister group connections to Eurasia. Using this framework, we describe the regional patterns of oak diversity within North America and formally classify 62 species into nine major North American subsections within sections Lobatae (the red oaks) and Quercus (the Citation: Manos, P.S.; Hipp, A.L. An Quercus Updated Infrageneric Classification white oaks), the two largest sections of subgenus . We also distill emerging evolutionary and of the North American Oaks (Quercus biogeographic patterns based on the impact of phylogenomic data on the systematics of multiple Subgenus Quercus): Review of the species complexes and instances of hybridization. -
