Vegetation Survey of Mount Gorongosa
VEGETATION SURVEY OF MOUNT GORONGOSA Tom Müller, Anthony Mapaura, Bart Wursten, Christopher Chapano, Petra Ballings & Robin Wild 2008 (published 2012) Occasional Publications in Biodiversity No. 23 VEGETATION SURVEY OF MOUNT GORONGOSA Tom Müller, Anthony Mapaura, Bart Wursten, Christopher Chapano, Petra Ballings & Robin Wild 2008 (published 2012) Occasional Publications in Biodiversity No. 23 Biodiversity Foundation for Africa P.O. Box FM730, Famona, Bulawayo, Zimbabwe Vegetation Survey of Mt Gorongosa, page 2 SUMMARY Mount Gorongosa is a large inselberg almost 700 sq. km in extent in central Mozambique. With a vertical relief of between 900 and 1400 m above the surrounding plain, the highest point is at 1863 m. The mountain consists of a Lower Zone (mainly below 1100 m altitude) containing settlements and over which the natural vegetation cover has been strongly modified by people, and an Upper Zone in which much of the natural vegetation is still well preserved. Both zones are very important to the hydrology of surrounding areas. Immediately adjacent to the mountain lies Gorongosa National Park, one of Mozambique's main conservation areas. A key issue in recent years has been whether and how to incorporate the upper parts of Mount Gorongosa above 700 m altitude into the existing National Park, which is primarily lowland. [These areas were eventually incorporated into the National Park in 2010.] In recent years the unique biodiversity and scenic beauty of Mount Gorongosa have come under severe threat from the destruction of natural vegetation. This is particularly acute as regards moist evergreen forest, the loss of which has accelerated to alarming proportions. -

Pericarp Ultrastructure of Salvia Section Hemisphace (Mentheae; Nepetoideae; Lamiaceae) Ahmet KAHRAMAN1, *, Hatice Nurhan BÜYÜKKARTAL2, Musa DOĞAN3

(sage), which belongs to the tribe Mentheae of the subfamily Nepetoideae within the family Lamiaceae, is well-known for its medicinal, ornamental, culinary and hallucinogenic uses. The section Hemisphace Benth. of this genus is respresented in Turkey by three species. The present study is conducted on two morphologically similar Salvia species belonging to this section: Salvia napifolia Jacq. and S. russellii Benth. (excluding S. verticillata L.). For this purpose, the pericarp ultrastructure of these species is investigated in detail with the help of light and transmission electron microscopy (TEM). Morphometric characters are analyzed using one-way Analysis of Variance (ANOVA) with Tukey’s honestly significant difference (HSD) post-hoc test for multiple comparisons. The taxonomic potential of pericarp characteristics is discussed. The most prominent traits are the thickness of the pericarp, mesocarp and sclerenchyma region that permit the separation of the species studied. Myxocarpy (mucilage formation) is recognized on the surface of the wetted mericarps of both species. Mucilaginous cells reveal a moderate reaction but S. -
933 the Field of Molecular Phylogenetics Has Progressed Tremen
American Journal of Botany 99(5): 933–953. 2012. P HYLOGENETICS, BIOGEOGRAPHY, AND STAMINAL EVOLUTION IN 1 THE TRIBE MENTHEAE (LAMIACEAE) B RYAN T . D REW 2,3 , AND K ENNETH J. SYTSMA 2 2 Department of Botany, University of Wisconsin, Madison, Wisconsin 53706 USA • Premise of the study: The mint family (Lamiaceae) is the sixth largest family of fl owering plants, with the tribe Mentheae containing about a third of the species. We present a detailed perspective on the evolution of the tribe Mentheae based on a phylogenetic analysis of cpDNA and nrDNA that is the most comprehensive to date, a biogeographic set of analyses using a fossil-calibrated chronogram, and an examination of staminal evolution. • Methods: Data from four cpDNA and two nrDNA markers representing all extant genera within the tribe Mentheae were ana- lyzed using the programs BEAST, Lagrange, S-DIVA, and BayesTraits. BEAST was used to simultaneously estimate phylog- eny and divergence times, Lagrange and S-DIVA were used for biogeographical reconstruction, and BayesTraits was used to infer staminal evolution within the tribe. • Key results: Currently accepted subtribal delimitations are shown to be invalid and are updated. The Mentheae and all fi ve of its subtribes have a Mediterranean origin and have dispersed to the New World multiple times. The vast majority of New World species of subtribe Menthinae are the product of a single dispersal event in the mid-late Miocene. At least four transitions from four stamens to two stamens have occurred within Mentheae, once in the subtribe Salviinae, once in the subtribe Lycopinae, and at least twice in the subtribe Menthinae. -
Constitutive and Facultative Crassulacean Acid Metabolism (CAM) in Cuban Oregano, Coleus Amboinicus (Lamiaceae)
CSIRO PUBLISHING Functional Plant Biology, 2021, 48, 647–654 https://doi.org/10.1071/FP20127 Constitutive and facultative crassulacean acid metabolism (CAM) in Cuban oregano, Coleus amboinicus (Lamiaceae) Klaus Winter A,C, Aurelio Virgo A, Milton GarciaA, Jorge ArandaA and Joseph A. M. Holtum A,B ASmithsonian Tropical Research Institute, PO Box 0843-03092, Balboa, Ancón, Republic of Panama. BCollege of Science and Engineering, James Cook University, Townsville, Qld 4811, Australia. CCorresponding author. Email: [email protected] Abstract. Plants exhibiting the water-conserving crassulacean acid metabolism (CAM) photosynthetic pathway provide some of the most intriguing examples of photosynthetic diversity and plasticity. Here, a largely unnoticed facet of CAM-plant photosynthesis is highlighted: the co-occurrence of ontogenetically controlled constitutive and environmentally controlled facultative CAM in a species. Both forms of CAM are displayed in leaves of Coleus amboinicus Lour. (Lamiaceae), a semi-succulent perennial plant with oregano-like flavour that is native to southern and eastern Africa and naturalised elsewhere in the tropics. Under well-watered conditions, leaves assimilate CO2 predominantly by the C3 pathway. They also display low levels of CO2 uptake at night accompanied by small nocturnal increases in leaf tissue acidity. This indicates the presence of weakly expressed constitutive CAM. CAM expression is strongly enhanced in response to drought stress. The drought-enhanced component of CAM is reversible upon rewatering and thus considered to be facultative. In contrast to C. amboinicus, the thin-leaved closely related Coleus scutellarioides (L.) Benth. exhibits net CO2 fixation solely in the light via the C3 pathway, both under well- watered and drought conditions. -
