Assessment Information Red List Category & Criteria: Least Concern ver 3.1 Year Published: 2013 Date Assessed: April 29, 2009 Justification: Myrtillocactus schenckii is considered to be Least Concern due to relatively abundant populations, lack of threats and its occurrence in protected areas. Geographic Range Range Description: This species occurs in the Mexican States of Chiapas, Oaxaca and Puebla (Arias et al. 1997) and in Guatemala. It grows at elevations of 1,300 to 2,000 m asl. Country Occurrence: Native: Guatemala; Mexico (Chiapas, Oaxaca, Puebla) © The IUCN Red List of Threatened Species: Myrtillocactus schenckii – published in 2013. 1 http://dx.doi.org/10.2305/IUCN.UK.2013-1.RLTS.T152217A611008.en Population This species is abundant and the subpopulations are stable. Current Population Trend: Stable Habitat and Ecology (see Appendix for additional information) The species occurs in tropical deciduous forest and xerophyllous scrub (Arias et al. 1997). The seeds are dispersed by birds, bats and humans. Systems: Terrestrial Use and Trade (see Appendix for additional information) The fruit is eaten locally. Threats (see Appendix for additional information) There are no major threats. However, traditional agro-silvicultural systems that enhances the maintenance of diversity are being substituted by practices that eliminate the vegetation cover, which does not benefit the species (Casas et al. 2006). Conservation Actions (see Appendix for additional information) The species is distributed within the Tehuacán-Cuicatlán Bisphere Reserve (Méndez-Larios et al. 2006). Monitoring populations and the process of domestication are research priorities. Credits Assessor(s): Arias, S. & Zavala-Hurtado, A. Reviewer(s): Superina, M. & Goettsch, B.K.

In situ management includes let standing, encouraging growing and protection of individual plants of useful Downloaded from species during clearance of vegetation, which in some cases may involve artificial selection.

However, there are few scientific studies regarding its characterization and use. For these reasons, in this study we carried out a chemical characterization of the juice of four-color variants as well as determine the antihyperglycemic capacity of seed. Physical and chemical characterization were carried out in juice of fruits of Stenocereus after a preselection based on pulp color. Total soluble solids, pH, titratable acidity, organic acid and betalains were quantified in juice and antihyperglycemic capacity was measured in seed.

  • Cacti Are Particularly Plentiful in Mexico's Arid, Warm, Dry
    EcoLOGY CACTI Salvador Arias Montes . acti are particularly plentiful in Mexico's arid, warm, dry regions. Over the last several de- cades, important floristic, systematic and eco logical studies, and others which look into Csustainable management of natural resources, have made cacti one of their research priorities. Because of their strange shapes and colorful flowers, many cacti are also used for decoration. This has made them increasingly important items on the ornamental plant market, which has expanded considerably in recent years. WHAT Is A CACTUS? Cacti are distinguished from other groups of plants or botanical families by the particular morphology of their stems and flowers. Without going into great technical detail, they are practically without leaves, although there are some notable exceptions like the Pereskia lychnidiflo- ra (matiare) and the Pereskiopsis aquosa (water prickly pear). They usually have spines (there are exceptions to this also, such as the Lophophora wilüamsü [peyote]), and their fleshy stocks take many different shapes. For example, some are flat and shaped like tennis rackets, the Botanical Ganien's Cacti Labotatoty at the UNAM *Researcher in Cacti come in a myriad of shapes and sizes.

  • (CACTACEAE) Teresa Terrazas Perforated Ray Cells Are
    IAWA Journal, Vol. 21 (4), 2000: 457–462 OCCURRENCE OF PERFORATED RAY CELLS IN GENERA OF PACHYCEREEAE (CACTACEAE) by Teresa Terrazas Programa de Botánica, Colegio de Postgraduados, Montecillo, Estado de México 56230, Mexico SUMMARY Perforated ray cells are reported for the first time for 16 species of seven genera of Pachycereeae. The perforated ray cells are shorter than vessel elements and have simple perforation plates and small alternate intervas- cular pits. Among Cactaceae these specialised cells seem to be related with splitting of the tall rays. Key words: Perforated ray cells, Pachycereeae, columnar cacti, Cacta- ceae. INTRODUCTION Perforated ray cells, or ray cells of the same dimensions or larger than the adjacent cells, but with perforations, have been recorded in a number of unrelated families (Chalk & Chattaway 1933; Carlquist 1988). Carlquist (1961) noted that perforated ray cells are derived from ray initials and possess either simple or scalariform perfo- ration plates, matching the other vessel elements in the species. McLean and Richardson (1973) suggested that perforated ray cells may function as a part of the vertical con- ducting system of the xylem and named them vascular ray cells. Although perforated ray cells are commonly confined to exclusively uniseriate rays or uniseriate exten- sions of tall multiseriate rays (Carlquist 1988; Nagai et al. 1994; Eom & Chung 1996), they occasionally occur in the multiseriate portion of wide rays (Bottoso & Gomes 1982; Dayal et al. 1984; Rao et al. 1984). The diagnostic value of these cells has been questioned by several authors (Rudall 1985; Carlquist 1988; IAWA Committee 1989). However, based on ontogeny Otegui (1994) argued in favour of their diagnostic value among species of Rapanea (Myrsinaceae).

Additionally, geographical distribution, endemism and conservation status of the species were analyzed based on a compiled data matrix with 2326 georeferenced records. Cactaceae comprises 137 species and 29 genera in Durango, which represent a high proportion of the Mexican cactus flora: 46−58% at the generic level and 20−23% at the specific level. The estimated richness according to Chao-2 and Jackknife-1 is 143 and 151 species respectively, which means that the inventory we present here for the Cactaceae of Durango is complete in 91 to 96%. Since no herbarium specimens nor registers in reliable data bases were found to support their presence in the area, 46 taxa were excluded; even so, this inventory increases by 30% the cacti richness previously reported for Durango and provides new information on the distribution range of many species.

Silvicultural management consists in sparing and enhancing selectively, in disturbed areas, individual trees producing fruits of the better quality for consumption and commercialisation. Fruits of trees in silviculturally managed populations are generally larger (27.23 6 0.39 cm) and heavier (11.10 6 0.44 g), with a higher amount of pulp (4.84 6 0.27 g), and more (532.72 6 15.60) and heavier (0.78 6 0.013 mg) seeds than in wild non-manipulated populations (22.62 6 0.31 cm, 6.44 6 0.22 g, 2.33 6 0.11 g, 407.63 6 20.67, and 0.62 6 0.015 mg, respectively).

Wild and managed populations were compared in morphology and reproductive biology to analyse if human selection has influenced phenotypic divergence, if it has modified breeding systems and if reproductive isolation exists between them. Fruits from managed populations were larger (6?3670?17 cm3), heavier (19?6271?32), sweeter (9?0770?25 1Brix), and with thinner peel (2?0970?13 mm) than those from wild populations (5?7770?18 cm3,15?7370?85 g, 8?2370?31 1Brix, and 2?5870?14 mm, respectively). Both population types bloom synchronically, show diurnal anthesis, with bees as the most likely pollinators, and have breeding system predominantly self-incompatible. Spatial and temporal barriers to pollen exchange between wild and managed populations are unlikely, and morphological differences would be related with an ongoing process of artificial selection. # 2002 Elsevier Science Ltd.
