Vol. 55, No. 3 May - June 2018 Mammilaria Ginsa Maru www.hcsstex.org by Rachel McKellar 1 Vol. 55, No. 3 May - June 2018 Membership Kathy Fewox The HCSS meeting scheduled for March 28, 2018 was canceled earlier that day due to predicted torrential thunderstorms and possible flooding throughout Houston. After our experience with Hurricane Harvey, I’m sure none of us wanted to risk being caught in high water, so canceling the meeting was a good call. Our April 25, 2018 meeting was attended by twenty-three members, including two new members who joined at the meeting. Please welcome Angeles and Edward Rojas to the club! Also attending the meeting were three guests: Carolina Paez, Lynne Schafer, and Suzanne Siegel. Several members donated some wonderful door prizes. Dave Thomas brought in a Euphorbia “Briar Patch,” which was quickly snapped up by Milton Pierson. Karla Halpaap-Wood provided a very nice Golden Barrel cactus pup, which went home with Cindy Gray. Liliana Cracraft donated a set of beautiful beaded cactus coasters, which was won by Imtiaz Bangee. Cindy Gray was extra generous – she brought in two Gasteraloe “Green Ice” plants, which went home with Karla Halpaap-Wood and Edward Rojas. Cindy also donated two Huernia scheideriana plants, which were won by Ray Gonzalez and Bruce Moffett. It is my sad duty to report the loss of Paul Stricklin’s mother, Rae Milton, who passed away on March 24, 2018. Rae was also a long-time member of HCSS. Our thoughts and prayers are with Paul and their family. As always, please send any news of HCSS members and their families to [email protected]. -

Ecological Niche Modeling Meets Phylogeography to Unravel Hidden Past History of Key Forest Genera in Plant Geography: Podocarpus and Nothofagus
Research Letters Natureza & Conservação 10(2):160-168, December 2012 Copyright© 2012 ABECO Handling Editor: José Alexandre F. Diniz-Filho Brazilian Journal of Nature Conservation http://dx.doi.org/10.4322/natcon.2012.036 Ecological Niche Modeling Meets Phylogeography to Unravel Hidden Past History of Key Forest Genera in Plant Geography: Podocarpus and Nothofagus Andrea Cecilia Premoli*, Maria Paula Quiroga, Paula Mathiasen & Thomas Kitzberger Laboratorio Ecotono, CRUB Universidad Nacional del Comahue – INIBIOMA CONICET, Bariloche, Argentina Abstract Phylogeographical methods and ecological niche modeling of cold-tolerant taxa, Podocarpus parlatorei a montane tropical conifer and Nothofagus pumilio inhabiting temperate areas of the southern Andes, were used as case studies to test if present populations are the result of local survival during cooling. Samples collected along their ranges were analyzed by nuclear isozymes and uniparentally inherited chloroplast DNA sequences. Modern and past last glacial maximum (LGM) ecological niche modeling (ENM) was developed using current climate data based on 19 bioclimatic variables and topography. Populations of the subtropical of P. parlatorei shared most haplotypes, southern populations were genetically distinct, and ENM yielded range expansion during the LGM. Latitudinally extreme populations of the temperate N. pumilio shared isozyme variants which was consistent with ENM showing suitable northern and southern areas. In contrast cpDNA yielded an ancient phylogeographic structure. Cold-hardy trees locally persisted along their ranges through ice periods without major range shifts in tropical and temperate regions. Key words: Chloroplast DNA, Cold-tolerant Trees, Distribution Modeling, Montane Subtropical, Temperate Andes. Introduction Phylogeographical analyses based on conserved molecular the long distance migration process yet they will also be markers are being widely used for biogeographic genetically similar to source populations due to shared reconstructions and to understand past history. -

Grau1, 3 P. G. Aceñolaza1 A.D. Brown1 Abstract Floristic composition and tree size distribution of different forest patches were studied between 1600 and 1800 m altitude in the Subtropical Montane Forests of Parque Biológico Sierra de San Javier, Argentina. Quadrats (20 x 20 m) were sampled in 12 sites. Sites were ordered using correspondence analysis. The first ordination axis was clearly associated to a gradient in complexity and diversity. The less complex forests were dominated by Alnus acuminata, Podocarpus parlatorei, and Crinodendron tucumanum. Richest and most complex forests were dominated by Myrtaceae species such as Blepharocalyxsalicifolius, Myrcianthes mato and Myrcianthes pseudomato, accompanied by Cedrela lilloi, Ilex argentina, Prunus tucumanensis, and others. Intermediate values of diversity and complexity were found in mature forests of A. acuminata and P. parlatorei, and in forests dominated by the treelets Dunalia lorentzii, Sambucus peruviana and Solanum grossum. Sites were grouped using the Twinspan software package. Within each cluster, diameter distribution of the most important species was used to describe regeneration trends. Myrtaceae species showed an "inverted-J" distribution of diameter, suggesting a continous regeneration mode. On the other hand, species which dominate simple forests such as A. acuminata, P. parlatorei, and C. tucumanum showed bell-shaped diameter distribution, suggesting lack of regeneration under the canopy. These conclusions were also supported by seedling and sapling densities. -

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. -
Morphology and Anatomy of Pollen Cones and Pollen in Podocarpus Gnidioides Carrière (Podocarpaceae, Coniferales)
1 2 Bull. CCP 4 (1): 36-48 (6.2015) V.M. Dörken & H. Nimsch Morphology and anatomy of pollen cones and pollen in Podocarpus gnidioides Carrière (Podocarpaceae, Coniferales) Abstract Podocarpus gnidioides is one of the rarest Podocarpus species in the world, and can rarely be found in collections; fertile material especially is not readily available. Until now no studies about its reproductive structures do exist. By chance a 10-years-old individual cultivated as a potted plant in the living collection of the second author produced 2014 pollen cones for the first time. Pollen cones of Podocarpus gnidioides have been investigated with microtome technique and SEM. Despite the isolated systematic position of Podocarpus gnidioides among the other New Caledonian Podocarps, it shows no unique features in morphology and anatomy of its hyposporangiate pollen cones and pollen. Both the pollen cones and the pollen are quite small and belong to the smallest ones among recent Podocarpus-species. The majority of pollen cones are unbranched but also a few branched ones are found, with one or two lateral units each of them developed from different buds, so that the base of each lateral cone-axis is also surrounded by bud scales. This is a great difference to other coniferous taxa with branched pollen cones e.g. Cephalotaxus (Taxaceae), where the whole “inflorescence” is developed from a single bud. It could be shown, that the pollen presentation in the erect pollen cones of Podocarpus gnidioides is secondary. However, further investigations with more specimens collected in the wild will be necessary. Key words: Podocarpaceae, Podocarpus, morphology, pollen, cone 1 Introduction Podocarpus gnidioides is an evergreen New Caledonian shrub, reaching up to 2 m in height (DE LAUBENFELS 1972; FARJON 2010). -

Read Full License Page 1/23 Abstract This study aims to investigate the phylogenetic relationships within the Juglandaceae family based on the Internal Transcribed Spacer's primary sequence and secondary structures (ITS2). Comparative analysis of 51 Juglandaceae species was performed across most of the dened seven genera. The results showed that the ITS2 secondary structure's folding pattern was highly conserved and congruent with the eukaryote model. Firstly, Neighbor-joining (N.J.) analysis recognized two subfamilies: Platycaryoideae and Engelhardioideae. The Platycaryoideae included the Platycaryeae (Platycarya+ (Carya+ Annamocarya)) and Juglandeae (Juglans-(Cyclocarya + Pterocarya)). The Engelhardioideae composed the (Engelhardia+Oreomunnea+Alfaroa)). The Rhoiptelea genus was generally regarded as an outgroup when inferring the phylogeny of Juglandaceae. However, it is clustered into the Juglandaceae family and showed a close relationship with the Platycaryoideae subfamily. Secondly, the folded 3-helices and 4-helices secondary structure of ITS2 were founded in the Juglandaceae family. Therefore, these ITS2 structures could be used as formal evidence to analyze Juglandaceae's phylogeny relationship.
