Grasslands ecosystems, endangered species, and sustainable ranching in the Mexico-U.S. borderlands: Conference proceedings. RMRS-P-40. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 126 p. Abstract The semi-arid grasslands in the Mexico-United States border region are relatively intact and provide one of the best opportunities in North America to preserve and nurture an extensive series of grassland ecosystems. The conference was organized to increase appreciation for the importance of the remaining semi-arid grasslands and to create a platform for expanding the integration of natural and social sciences among individuals and organizations. The conference was attended by ranchers, environmentalists, academics, and agency personnel from both nations. Main topics include grassland ecology and biodiversity, management and conservation, and sustainable borderland ranching. Endangered species management, especially of black-tailed prairie dogs (Cynomys ludovicianus), was an important topic. Oral presentations were in English or Spanish, with simultaneous translations, and the papers have been printed in both languages. The conference revealed the ties between ecological processes and environmental conditions in the Borderland grasslands and the cultural and economic priorities of the human communities who depend on them. This recognition should enable interested people and groups to work together to achieve satisfactory solutions to the challenges of the future.

  • The Vegetation of Robinson Crusoe Island (Isla Masatierra), Juan
    The Vegetation ofRobinson Crusoe Island (Isla Masatierra), Juan Fernandez Archipelago, Chile1 Josef Greimler,2,3 Patricio Lopez 5., 4 Tod F. Stuessy, 2and Thomas Dirnbiick5 Abstract: Robinson Crusoe Island of the Juan Fernandez Archipelago, as is the case with many oceanic islands, has experienced strong human disturbances through exploitation ofresources and introduction of alien biota. To understand these impacts and for purposes of diversity and resource management, an accu­ rate assessment of the composition and structure of plant communities was made. We analyzed the vegetation with 106 releves (vegetation records) and subsequent Twinspan ordination and produced a detailed colored map at 1: 30,000. The resultant map units are (1) endemic upper montane forest, (2) endemic lower montane forest, (3) Ugni molinae shrubland, (4) Rubus ulmifolius­ Aristotelia chilensis shrubland, (5) fern assemblages, (6) Libertia chilensis assem­ blage, (7) Acaena argentea assemblage, (8) native grassland, (9) weed assemblages, (10) tall ruderals, and (11) cultivated Eucalyptus, Cupressus, and Pinus. Mosaic patterns consisting of several communities are recognized as mixed units: (12) combined upper and lower montane endemic forest with aliens, (13) scattered native vegetation among rocks at higher elevations, (14) scattered grassland and weeds among rocks at lower elevations, and (15) grassland with Acaena argentea. Two categories are included that are not vegetation units: (16) rocks and eroded areas, and (17) settlement and airfield. Endemic forests at lower elevations and in drier zones of the island are under strong pressure from three woody species, Aristotelia chilensis, Rubus ulmifolius, and Ugni molinae. The latter invades native forests by ascending dry slopes and ridges.

SUMMARY In Chile’s Mediterranean region, over 18% of plant species are alien. This is particularly noteworthy in some agrosilvopastoral systems such as the espinales, which are functionally very similar to the Spanish dehesas and are of great ecological and socioeconomic interest. In the present paper we analyse Chile’s non-native flora, considering three scales of analysis: national, regional (the central region, presenting a Mediterranean climate) and at community level (the espinales within the central region). We compare this flora with that recorded in areas of the Iberian Peninsula with similar lithological and geomorphological characteristics, and land use. We discuss possible mechanisms that might have been operating in the floristic colonisation from the Mediterranean Basin to Chile’s Mediterranean region. Key words: Alien plants, biogeography, Chile, life cycle, Spain. INTRODUCTION Historically, the transit of goods, domestic animals and people has favoured the flow of wild organisms around the planet (Lodge et al., 2006), a fact that is often associated with the introduction of cultural systems, which have contributed to generating new environmental and socioeconomic scenarios (Le Houérou, 1981; Hobbs, 1998; Grenon and Batisse, 1989).

  • Chromosome Numbers in Compositae, XII: Heliantheae
    SMITHSONIAN CONTRIBUTIONS TO BOTANY 0 NCTMBER 52 Chromosome Numbers in Compositae, XII: Heliantheae Harold Robinson, A. Michael Powell, Robert M. King, andJames F. Weedin SMITHSONIAN INSTITUTION PRESS City of Washington 1981 ABSTRACT Robinson, Harold, A. Michael Powell, Robert M. King, and James F. Weedin. Chromosome Numbers in Compositae, XII: Heliantheae. Smithsonian Contri- butions to Botany, number 52, 28 pages, 3 tables, 1981.-Chromosome reports are provided for 145 populations, including first reports for 33 species and three genera, Garcilassa, Riencourtia, and Helianthopsis. Chromosome numbers are arranged according to Robinson’s recently broadened concept of the Heliantheae, with citations for 212 of the ca. 265 genera and 32 of the 35 subtribes. Diverse elements, including the Ambrosieae, typical Heliantheae, most Helenieae, the Tegeteae, and genera such as Arnica from the Senecioneae, are seen to share a specialized cytological history involving polyploid ancestry. The authors disagree with one another regarding the point at which such polyploidy occurred and on whether subtribes lacking higher numbers, such as the Galinsoginae, share the polyploid ancestry. Numerous examples of aneuploid decrease, secondary polyploidy, and some secondary aneuploid decreases are cited. The Marshalliinae are considered remote from other subtribes and close to the Inuleae. Evidence from related tribes favors an ultimate base of X = 10 for the Heliantheae and at least the subfamily As teroideae.

  • A Tale of Two Cacti –The Complex Relationship Between Peyote (Lophophora Williamsii) and Endangered Star Cactus (Astrophytum Asterias)
    A Tale of Two Cacti –The Complex Relationship between Peyote (Lophophora williamsii) and Endangered Star Cactus (Astrophytum asterias). 1 2 2 TERRY, M. , D. PRICE , AND J. POOLE. 1Sul Ross State University, Department of Biology, Alpine, Texas 79832. 2Texas Parks and Wildlife Department, Wildlife Diversity Branch, 3000 S. IH-35, Suite 100, Austin, Texas 78704. ABSTRACT Astrophytum asterias, commonly called star cactus, is a federally listed endangered cactus endemic to the Tamaulipan thornscrub ecoregion of extreme southern Texas, USA, and Tamaulipas and Nuevo Leon, Mexico. Only three metapopulations totaling less than 4000 plants are presently known in Texas. Star cactus, known locally as “star peyote”, is highly sought by collectors. This small, dome-shaped, spineless, eight- ribbed cactus is sometimes mistaken for peyote (Lophophora williamsii), which grows in the same or adjacent habitats. Peyote is harvested from native thornscrub habitats in Texas by local Hispanic people and sold to peyoteros, licensed distributors who sell the peyote to Native American Church members. Annual peyote harvests in Texas approach 2,000,000 “buttons” (crowns). Although the peyoteros do not buy star cactus from harvesters, they cultivate star cactus in peyote gardens at their places of business and give star cacti to their customers as lagniappe. If even 0.1% of harvested “peyote” is actually star cactus, the annual take of this endangered cactus approaches the total number of wild specimens known in the U.S. This real but unquantifiable take, together with information from interviews with local residents, suggests the existence of many more star cactus populations than have been documented.

  • The Chaparral Vegetation in Mexico Under Nonmediterranean Climate: the Convergence and Madrean-Tethyan Hypotheses Reconsidered1

The comparison considered ¯oristic composition, plant-community struc- ture, and plant characters as adaptations to mediterranean climates and analyzed them by means of a correspondence analysis, considering a tropical spiny shrubland as the external group. We made a species register of the number of species that resprouted after a ®re occurred in 1995 and a distribution map of the evergreen sclerophyllous vegetation in Mexico (mexical) under nonmediterranean climates. The TehuacaÂn mexical does not differ from the evergreen sclerophyllous areas of Chile, California, Australia, and the Mediterranean Basin, according to a correspondence analysis, which ordinated the TehuacaÂn mexical closer to the mediter- ranean areas than to the external group. All the vegetation and ¯oristic characteristics of the mexical, as well as its distribution along the rain-shadowed mountain parts of Mexico, support its origin in the Madrean-Tethyan hypothesis of Axelrod. Therefore, these results allow to expand the convergence paradigm of the chaparral under an integrative view, in which a general trend to aridity might explain ¯oristic and adaptive patterns detected in these environments.

  • The Three Mediterranean Climates
    Middle States Geographer, 2005, 38:52-60 THREE CONFLATED DEFINITIONS OF MEDITERRANEAN CLIMATES Mark A. Blumler Department of Geography SUNY Binghamton Binghamton, NY 13902-6000 ABSTRACT: "Mediterranean climate" has in effect three different definitions: 1) climate of the Mediterranean Sea and bordering land areas; 2) climate that favors broad-leaved, evergreen, sclerophyllous shrubs and trees; 3) winter-wet, summer-dry climate. These three definitions frequently are conflated, giving rise to considerable confusion and misstatement in the literature on biomes, vegetation-environment relationships, and climate change. Portions of the Mediterranean region do not have winter-wet, summer-dry climate, while parts that do, may not have evergreen sclerophylls. Places away from the Mediterranean Sea, such as the Zagros foothills, have more mediterranean climate than anywhere around the Sea under the third definition. Broad-leaved evergreen sclerophylls dominate some regions with non-mediterranean climates, typically with summer precipitation maximum as well as winter rain, and short droughts in spring and fall. Thus, such plants may be said to characteristize subtropical semi-arid regions. On the other hand, where summer drought is most severe, i.e., the most mediterranean climate under definition 3, broad-leaved evergreen sclerophylls are rare to absent. Rather than correlating with sclerophyll dominance, regions of extreme winter-wet, summer-dry climate characteristically support a predominance of annuals, the life form best adapted to seasonal rainfall regimes. Given the importance of useful forecasting of vegetation and climate change under greenhouse warming, it is imperative that biome maps begin to reflect the complexities of vegetation-climate relationships. INTRODUCTION literature also is replete with inaccurate statements about mediterranean regions.
