Biodiversidad En Campeche Reino Vegetal
Biodiversidad en Campeche Reino Vegetal Macroalgas INTRODUCC I ÓN Las macroalgas son organismos eucariontes multicelulares, fotoau- tótrofos, de arquitectura clonal y estrategia de crecimiento modular, marinos y asociados al sustrato (son bentónicos). Los grupos prin- cipales son las algas verdes (Chlorophyta), las pardas o café (Hete- rokontophyta) y las rojas (Rhodophyta). Constituyen junto a Cyano- bacteria y Eubacteria (Prokaria) grupos evolutivamente ancestrales en Abel Sentíes G. relación, por ejemplo, con las plantas terrestres (quienes comparten y Kurt M. Dreckmann un ancestro común con Chlorophyta). En el mismo tenor, ancestros del tipo rhodophyta, cyanobacteria y eubacteria, a lo largo de eventos endosimbióticos, dieron lugar a la actual organización eucarionte (el primer eucarionte conocido es un fósil del tipo rhodophyta encontrado en rocas de 2.1 billones de años (Brodie y Lewis, 2007). Si bien son grupos morfo-anatómicamente sencillos, las macroalgas despliegan fisiologías y comportamientos reproductivos y ecológicos altamente complejos. DI VERS I DAD El grupo de las algas, en general, puede ser categorizado de acuerdo a su tamaño, en micro y macroalgas. Aquellas que van desde menos de 10 hasta 100 micrometros son consideradas microalgas (forman parte del fitoplancton), y son el objeto de estudio de la microficología, aquellas que van desde las 100 micras (visibles porque miden más de 1 milímetro) a varias decenas de centímetros (como el caso de Macro- 198 La Biodiversidad en Campeche cystis piryfera o kelps que llega a medir más de 30) son categorizadas como macroalgas y son el objeto de estudio de la ficología marina. Al- rededor de 350 000 especies de algas han sido descritas en los últimos 200 años (Brodie y Zucarello, 2007). -
Floristic and Ecological Characterization of Habitat Types on an Inselberg in Minas Gerais, Southeastern Brazil
Acta Botanica Brasilica - 31(2): 199-211. April-June 2017. doi: 10.1590/0102-33062016abb0409 Floristic and ecological characterization of habitat types on an inselberg in Minas Gerais, southeastern Brazil Luiza F. A. de Paula1*, Nara F. O. Mota2, Pedro L. Viana2 and João R. Stehmann3 Received: November 21, 2016 Accepted: March 2, 2017 . ABSTRACT Inselbergs are granitic or gneissic rock outcrops, distributed mainly in tropical and subtropical regions. Th ey are considered terrestrial islands because of their strong spatial and ecological isolation, thus harboring a set of distinct plant communities that diff er from the surrounding matrix. In Brazil, inselbergs scattered in the Atlantic Forest contain unusually high levels of plant species richness and endemism. Th is study aimed to inventory species of vascular plants and to describe the main habitat types found on an inselberg located in the state of Minas Gerais, in southeastern Brazil. A total of 89 species of vascular plants were recorded (belonging to 37 families), of which six were new to science. Th e richest family was Bromeliaceae (10 spp.), followed by Cyperaceae (seven spp.), Orchidaceae and Poaceae (six spp. each). Life forms were distributed in diff erent proportions between habitats, which suggested distinct microenvironments on the inselberg. In general, habitats under similar environmental stress shared common species and life-form proportions. We argue that fl oristic inventories are still necessary for the development of conservation strategies and management of the unique vegetation on inselbergs in Brazil. Keywords: endemism, granitic and gneissic rock outcrops, life forms, terrestrial islands, vascular plants occurring on rock outcrops within the Atlantic Forest Introduction domain, 416 are endemic to these formations (Stehmann et al. -

He was not in mourning from the Crows loss. Margaret and I were giving the main talk on a visit to northern NSW and these days when we do such visits we are often asked for advice on names, never on culture. I wonder why? As such the meeting was on a querying note, where members had to have their brains in gear. -

Bromeliads Bromeliads Are a Family of Plants (Bromeliaceae, the Pineapple Family) Native to Tropical North and South America
A Horticulture Information article from the Wisconsin Master Gardener website, posted 19 March 2012 Bromeliads Bromeliads are a family of plants (Bromeliaceae, the pineapple family) native to tropical North and South America. Europeans fi rst found out about bromeliads on Columbus’ second trip to the New World in 1493, where the pineapple (Ananas sp.) was being cultivated by the Carib tribe in the West Indies. The commercial pineapple (Ananas comosus) is native to southern Brazil and Paraguay. After the colonization of the New World it was rapidly transported to all areas of the tropics, and now is widely grown in tropical and sub- tropical areas. The only A collection of bromeliads placed on a tree at Costa Flores, Costa Rica. bromeliad to occur north of the tropics is Spanish “moss” (Tillandsia usneoides). It is neither Spanish nor a moss, but an epiphytic bromeliad. It doesn’t look much like a typical Commercial pineapple, Ananas comosus, bromeliad, though, with its long scaly stems and reduced in the fi eld. fl owers. Bromeliads are monocots, many of which, like their grass relatives, have a special form of photosynthesis that uses a variation of the more usual biochemical pathways to allow them to use water more effi ciently. Even though they come from the tropics, this helps those that are epiphytes contend with life in the treetops where there is limited water and a real danger of drying out. There are about 2500 species Many bromeliads are tropical and several thousand hybrids epiphytes. and cultivars. Many have brightly colored leaves, fl owers or fruit, and range in size from moss-like species of Tillandsia to the enormous Puya raimondii from the Andes which produces a fl owering stem up to 15 feet tall. -
BOH: a Unique Chemical for the Induction of Flowering in Bromeliads
BOH: A Unique Chemical for the Induction of Flowering in Bromeliads Héctor R. Cibes and A. Santiago Nieves1 INTRODUCTION The pineapple family, Bromeliaceae, is composed of stemless herbs native to tropical America whence they have been disseminated to other areas of the world. They have stiff and sometimes spiny leaves. Their flowers are borne in panicles. Perhaps the most important genus of the family is Ananas, to which the commercial pineapple varieties belong. Other members of the family are noted for the fiber obtained from their leaves. Bromelia pinguin L., or wild pineapple, a native of the West Indies, is widely used as a hedge plant and its fruit is also known to contain a proteolytic enzyme. The genus Bromeha was named after the Swedish botanist, Olaf Bromelius. Bromeliads are becoming increasingly important as ornamental plants, both locally and in the United States. Not only the plants themselves are showy, because of their color, shape, and variegation, but also their flowers are beautiful. An important characteristic among bromeliads is that their flowers are long-lasting on the plants. Some will last, attached to the mother plant, for months without losing their beautiful appear ance. FLOWER INDUCTION However, flowering is not uniform in this group of plants. For instance, a pineapple field may flower sporadically 10 to 15 times throughout the year, after attaining the proper age. Thus, flower-forcing during a con venient time along the growing season is imperative in commercial plant ings. This is attainable through the use of suitable concentrations of either calcium carbide (CaC2), naphthalene acetic acid (NAA), or /3-hydroxyethyl hydrazine (BOH). -
