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). -

Several reference photos courtesy of “fcbs.org” September meeting from the Secretary’s desk It was a bit of a change to have Adam in the Chair while Len was trying to get home from Melbourne after a somewhat sorrowful visit. 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. -

Both hummingbirds and bats pollinate the species-rich and morphologically diverse genus Vriesea across its distribution in the Brazilian Atlantic Forest. Here, we (i) determine if floral traits predict functional groups of pollinators as documented, confirming the pollination syndromes in Vriesea and (ii) test if genetic structure in Vriesea is driven by geography (latitudinal and altitudinal heterogeneity) or ecology (pollination syndromes). -

Catalogue of the Vascular Epiphytic Flora of Uruguay
Acta Botanica Brasilica doi: 10.1590/0102-33062019abb0059 Catalogue of the vascular epiphytic flora of Uruguay Patricia Mai1* , Andrés Rossado2 , José Mauricio Bonifacino2,3 and Jorge Luiz Waechter4 Received: February 21, 2019 Accepted: June 17, 2019 . ABSTRACT We provide an updated list of the vascular epiphytic flora occurring in native environments of Uruguay based on literature review, herbarium specimens, and fieldwork throughout the country. The catalogue provides standardized information for each species, including accepted name, synonyms used within Uruguay, epiphytic category, distribution within the country, habitat, conservation status, observations, and a voucher citation. The effort documented 73 species for the epiphytic flora of Uruguay (3 % of the flora), distributed among 29 genera and 12 families. Bromeliaceae was the richest family (17), followed by Polypodiaceae (16) and Orchidaceae (12). Tillandsia stood out as the most speciose genus with 15 species. Characteristic holoepiphytes was the most diverse ecological category. More than half of the epiphytic species documented for Uruguay (53 %) reach their southernmost geographic distribution in the country, whereas only two mostly epipetric species of Tillandsia — T. arequitae and T. uruguayensis — are endemic to the country. Almost half of the epiphytic species found are presently under categories of threat of extinction, with 60 % of them occurring in national protected areas. Both the richest epiphytic families and the predominance of characteristic holoepiphytes coincide with findings from floristic and ecological studies previously carried out in humid subtropical regions. Keywords: conservation status, epiphytic category, geographic distribution, hemiepiphytes, holoepiphytes, subtropical forests, Uruguay, vascular epiphytes The most recent estimation of vascular epiphytes in the Introduction world reports 27,614 species, distributed in 73 families and 913 genera. -

However, little is known about the signalling pathway of ROS in plants with CAM metabolism, other than the knowledge that ROS production is limited in CAM plants. In the present study, we assessed the effects of drought stress on reactive oxygen species and antioxidant enzyme activities in leaf portions of Guzmania monostachia. The exposure of G. monostachia plants to 10 days of water deficit led to a decrease in the leaf relative water content (RWC) from 75% to 50% in all leaf portions (apical, middle and basal); hence, it was concluded that plants subjected to drought produced higher levels of reactive oxygen species (ROS) when compared with control plants. Significant variations to the formation of ROS were also identified in all leaf portions during the diurnal cycle. After ten days of CAM induction, H2O2 concentration increased significantly in contrast to control plants during the day-night cycle. In addition, the activity of antioxidant enzymes in processes related to the elimination of ROS was also evaluated. -
