Cactus Growth Changes As an Effect of Wind in Baja California Sur, México
BRIEF NOTE Cactus Growth Changes as an Effect of Wind in Baja California Sur, Mexico1 ALFREDO ORTEGA-RUBIO, HEIDI ROMERO-SCHMIDT, AND FERNANDO VEGA-VILLASANTE, Centro de Investigaciones Biologicas del Noroeste, A.P. 128, La Paz 23000, Baja California Sur, Mexico ABSTRACT. At Natividad Island, Baja California Sur, Mexico, we sampled a Ferocactus fordii var. grandi- florus population. All 50 individuals recorded in the northeast part of the island exhibited different degrees of prostration, directly related to their size and the direction of prevailing winds. Prostration was always oriented away from the direction of the dominant winds blowing over the island. There are essentially no previous publications of the effects of wind on the cactus growth form. OHIO J. SCI. 95 (5): 337-338, 1995 INTRODUCTION fringed by detached rocks and kelp; several reefs extend Ferocactus fordii (Ore.) Britt. & Rose var. grandiflorus off the NW side of the island (Lewis and Ebeling 1971). Lindsay is an endemic variety from the Vizcaino Desert The island vegetation is sarcophilous desert, mainly of the Baja California Peninsula, Mexico (Lindsay 1956) composed of annual herbs {Ambrosia sp., Atriplex sp.), (Fig. 1). Because of its endemic status there have been no small shrubs {Acacia sp.), and some cacti like "Cardon" previous studies concerning ecological aspects of this {Pachycereus pringlei), "Chollas" (Opuntia spp.), and variety. There exist only references to taxonomic aspects "Viejitos" (Mammillaria spp.). (Wiggins 1980, Innes and Glass 1991). Ferocactus fordii (Ore.)

Larger fruits with more seeds are ob- germination responses of freshly matured seeds of five species of served for F. histrix, whereas smaller fruits with less weight and Cacteae (Coryphantha bumamma, C. clavata, C. cornifera, Fero- fewer seeds are seen for C. clavata. Seed germination is a rapid cactus histrix and Mammillaria uncinata) were studied at room process and usually starts on the third day. High percentages of temperature under laboratory conditions. The aim of the study germination (>80%) are observed on the sixth day in F. histrix was to record the macro- and micro-morphology of fruits and and M. uncinata. It is concluded that some morphological cha- seeds of these species and to investigate specific requirements racteristics of fruits and seeds can be used to support further for germination. Variance analysis detected significant differen- systematic studies of Cactoideae genera and will contribute new ces (p<0.05) for several variables: number of seeds per fruit, knowledge for their potential use and conservation. -

Myxomycetes associated with dryland ecosystems of the Tehuacán-Cuicatlán Valley Biosphere Reserve, Mexico. Fungal Diversity 36: 17-56. The results of a biodiversity survey of a xeric Mexican Biosphere Reserve are presented. This survey represents the first intensive study of cacti and succulent plants ever carried out for myxomycetes. The results include 104 species and one variety, identified from 1200 records from field and moist chamber culture collections. Two new species (Didymium tehuacanense and Perichaena stipitata), found on decayed remains of succulent plants, are described. Eleven species (Comatricha reticulospora, Cribraria lepida, Didymium clavodecus, D. eremophilum, D. orthonemata, D. sturgisii, D. subreticulosporum, Licea belmontiana, Macbrideola oblonga, M. synsporos and Perichaena quadrata) are new records for the Neotropics, and seven others taxa have not been recorded previously from Mexico. Taxonomic comments, data on distribution and SM, LM and SEM micrographs of selected species are included. An analysis of the relationships that exist between myxomycetes and the substrates on which they develop confirms the presence of a distinct assemblage of myxomycetes associated with specific plants from arid environments. Hypotheses are proposed for the patterns of species distribution and the ecological requirements of this specialised myxobiota. -
Abstract Alelopatía Diferencial Entre Los Géneros De
MARCELA AVENDAÑO-GONZÁLEZ1, ERNESTO I. BADANO1,3, JORGE E. RAMÍREZ- ALBORES1, JOEL FLORES1, JORGE A. FLORES-CANO2 Abstract The Peruvian peppertree (Schinus molle) is a dioecious species from South America that was introduced into central Mexico fve centuries ago. This tree has invaded abandoned agricultural felds from semiarid regions, where it can be found with several native succulent plants that have recolonized these areas. Al- though peppertrees have negative allelopathic effects on crops, their effects on these native plants remain unknown. Indeed, the allelopathy of peppertrees has only been tested for female individuals, while the allelopathic potential of male peppertrees has not been assessed yet. This study focused on these issues and assessed whether peppertrees affect germination of succulent plants from the Chihuahuan Desert and whether these effects differ between male and female trees. For this we conducted a series of germina- tion bioassays where seeds of native species were watered with aqueous extracts of staminate fowers and leaves produced by male peppertrees, and with aqueous extracts of fruits and leaves produced by female peppertrees. Additionally, we conducted experiments where seeds of native species were sowed on soils collected beneath the canopy of both tree genders. The results of all these experiments indicated that both peppertree genders can reduce germination of native species, but also suggested that male peppertrees would have stronger allelopathic effects than female peppertrees. To our best knowledge, this is the frst study reporting allelopathic effects of peppertrees on native plants from Mexico, but this is also the frst study indicating differential gender effects for invasive dioecious species with allelopathic potential. -

An increasing number is escaping and naturalising, also in natural habitats in the Canary Islands (Spain). However, a detailed treatment of variously naturalised and invasive species found in the wild in the Canary Islands is not available and, as a result, species identification is often problematic. -
Cactus Island
CACTUS ISLAND AFRICA - AMERICA - MADAGASCAR AMERICA’S CACTUS ISLAND This Agave is a spectacular hybrid of green leaves with a red margin. It can be planted in full sun or in sun-shade. It should be planted in well-drained soil and watered once a month. During winter it is advisable not to water it too much to increase its resistance to cold. It is advisable to avoid that the snow accumulates between the leaves. Tª min approx -8 / -10 ºC. AGAVE ARISTOCRAT Agave salmiana var. ferox (Agave ferox) is a variety of the agave of the Salmiana species belonging to the genus Agave and family Asparagaceae. The ferox subspecies is very close to the typical subspecies in terms of description and culture. It differs by having even thicker and stiffer blades, pointed ends (up to 8 cm) and even sharper lateral spines. This is why it is called by that name. Place of origin: Mexico. AGAVE FEROX NOTES: Agaves tolerate arid and semi-desert areas well, in fact, they are usually the only survivors in abandoned gardens. Ideal for plantations that do not need care or irrigation. They prefer sunny and airy places, with well-drained soils. Very little or no watering if the plant grows in full soil. In a pot, they should be watered but very little. Agave lophantha is a plant native to the deserts of Chihuahua and Sonora. It forms a rosette of coriaceous leaves or leaves up to 45cm high and 60cm wide, with jagged edges. The flowers appear grouped in reddish-yellow inflorescences up to 4m high. -

Ecology of Old-Growth Forests in Chihuahua, México
THE TREASURE OF THE SIERRA MADRE: ECOLOGY OF OLD-GROWTH FORESTS IN CHIHUAHUA, MÉXICO By Citlali Cortés-Montaño A dissertation Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in Forest Science Northern Arizona University December 2011 Approved: Peter Z. Fulé, Ph.D., Chair Ernesto Alvarado-Celestino, Ph.D. Tina J. Ayers, Ph.D. Margaret M. Moore, Ph.D. José Villanueva-Díaz, Ph.D. Abstract THE TREASURE OF THE SIERRA MADRE: ECOLOGY OF OLD-GROWTH FORESTS IN CHIHUAHUA, MÉXICO By Citlali Cortés-Montaño Old-growth forests are valuable but declining worldwide. México still holds large areas covered by temperate forests in the mountains of the Sierra Madre Occidental, but few of these retain old-growth characteristics. These forests provide habitat for Thick- billed Parrots (Rhynchopsitta pachyrhyncha: Psittacidae; “guacamaya”), a CITES-listed endangered species. We studied four old-growth remnants in Mesa de las Guacamayas, a site in the Sierra Madre Occidental in Chihuahua, México, to assess the composition, structure, and age characteristics of the overstory, relating it to fire histories and continental and regional climatic data. We linked our findings to the habitat needs of Thick-billed Parrots reported by the literature, and we studied the β-diversity of the understory plant communities at these sites and related them to the composition, cover, density and fire regimes of the overstory. We found that frequent disturbance by surface fires appears to have contributed to maintaining open, diverse, and productive forests for at least 250 years. While climate was a historical driver of the fire regimes in this mountain range, humans appear to have played a role in the fire regime interruptions of the second half of the 20th century.
