Impacts of Global Climate Change on the Phenology of African Tropical Ecosystems
IMPACTS OF GLOBAL CLIMATE CHANGE ON THE PHENOLOGY OF AFRICAN TROPICAL ECOSYSTEMS GABRIELA S. ADAMESCU MSc by Research UNIVERSITY OF YORK Biology October 2016 1 Abstract The climate has been changing at an unprecedented rate, affecting natural systems around the globe. Its impact has been mostly reflected through changes in species’ phenology, which has received extensive attention in the current global-change research, mainly in temperate regions. However, little is known about phenology in African tropical forests. Africa is known to be vulnerable to climate change and filling the gaps is an urgent matter. In this study we assess plant phenology at the individual, site and continental level. We first compare flowering and fruiting events of species shared between multiple sites, accounting for three quantitative indicators, such as frequency, fidelity for conserving a certain frequency and seasonal phase. We complement this analysis by assessing interannual trends of flowering and fruiting frequency and fidelity to their dominant frequency at 11 sites. We complete the bigger picture by analysing flowering and fruiting frequency of African tropical trees at the site and community level. Next, we correlate three climatic indices (ENSO, IOD and NAO) with flowering and fruiting events at the canopy level, at 16 sites. Our results suggest that 30 % of the studied species show plasticity or adaptability to different environments and will most likely be resilient to moderate future climate change. At both site and continental level, we found that annual flowering cycles are dominant, indicating strong seasonality in the case of more than 50% of African tropical species under investigation. -

Towards Resolving Lamiales Relationships
Schäferhoff et al. BMC Evolutionary Biology 2010, 10:352 http://www.biomedcentral.com/1471-2148/10/352 RESEARCH ARTICLE Open Access Towards resolving Lamiales relationships: insights from rapidly evolving chloroplast sequences Bastian Schäferhoff1*, Andreas Fleischmann2, Eberhard Fischer3, Dirk C Albach4, Thomas Borsch5, Günther Heubl2, Kai F Müller1 Abstract Background: In the large angiosperm order Lamiales, a diverse array of highly specialized life strategies such as carnivory, parasitism, epiphytism, and desiccation tolerance occur, and some lineages possess drastically accelerated DNA substitutional rates or miniaturized genomes. However, understanding the evolution of these phenomena in the order, and clarifying borders of and relationships among lamialean families, has been hindered by largely unresolved trees in the past. Results: Our analysis of the rapidly evolving trnK/matK, trnL-F and rps16 chloroplast regions enabled us to infer more precise phylogenetic hypotheses for the Lamiales. Relationships among the nine first-branching families in the Lamiales tree are now resolved with very strong support. Subsequent to Plocospermataceae, a clade consisting of Carlemanniaceae plus Oleaceae branches, followed by Tetrachondraceae and a newly inferred clade composed of Gesneriaceae plus Calceolariaceae, which is also supported by morphological characters. Plantaginaceae (incl. Gratioleae) and Scrophulariaceae are well separated in the backbone grade; Lamiaceae and Verbenaceae appear in distant clades, while the recently described Linderniaceae are confirmed to be monophyletic and in an isolated position. Conclusions: Confidence about deep nodes of the Lamiales tree is an important step towards understanding the evolutionary diversification of a major clade of flowering plants. The degree of resolution obtained here now provides a first opportunity to discuss the evolution of morphological and biochemical traits in Lamiales. -

Hypoestes Aristata (Vahl) Sol
Biol Res 43: 403-409, 2010 BHATT ET AL. Biol Res 43, 2010, 403-409 B403R The foliar trichomes of Hypoestes aristata (Vahl) Sol. ex Roem. & Schult var aristata (Acanthaceae) a widespread medicinal plant species in tropical sub-Saharan Africa: with comments on its possible phylogenetic significance A. Bhatt*, Y. Naidoo and A. Nicholas School of Biological and Conservation Sciences, University of KwaZulu-Natal, Westville Campus, Private Bag X54001, Durban, KZN, 4000, South Africa ABSTRACT The micromorphology of foliar trichomes of Hypoestes aristata var. aristata was studied using stereo, light and scanning microscopy (SEM). This genus belongs to the advanced angiosperm family Acanthaceae, for which few micromorphological leaf studies exist. Results revealed both glandular and non-glandular trichomes, the latter being more abundant on leaf veins, particularly on the abaxial surface of very young leaves. With leaf maturity, the density of non-glandular trichomes decreased. Glandular trichomes were rare and of two types: long-stalked capitate and globose-like peltate trichomes. Capitate trichomes were observed only on the abaxial leaf surface, while peltate trichomes were distributed on both adaxial and abaxial leaf surfaces. Key terms: Acanthaceae, Glandular trichomes, Hypoestes aristata var. aristata, medicinal plant, Scanning electron microscope. INTRODUCTION zygomorphic flowers supported by prominent bracts and producing explosive capsular fruits. Many studies have The Family Acanthaceae is a large and diverse family of further supported the placement of Hypoestes in a smaller dicotyledonous plants comprising about 202 genera and 3520 clade that includes the prominent genus Justicia (McDade species (Judd et al., 2008); although estimates vary from 2600 and Moody 1999). -
Recommendation of Native Species for the Reforestation of Degraded Land Using Live Staking in Antioquia and Caldas’ Departments (Colombia)
UNIVERSITÀ DEGLI STUDI DI PADOVA Department of Land, Environment Agriculture and Forestry Second Cycle Degree (MSc) in Forest Science Recommendation of native species for the reforestation of degraded land using live staking in Antioquia and Caldas’ Departments (Colombia) Supervisor Prof. Lorenzo Marini Co-supervisor Prof. Jaime Polanía Vorenberg Submitted by Alicia Pardo Moy Student N. 1218558 2019/2020 Summary Although Colombia is one of the countries with the greatest biodiversity in the world, it has many degraded areas due to agricultural and mining practices that have been carried out in recent decades. The high Andean forests are especially vulnerable to this type of soil erosion. The corporate purpose of ‘Reforestadora El Guásimo S.A.S.’ is to use wood from its plantations, but it also follows the parameters of the Forest Stewardship Council (FSC). For this reason, it carries out reforestation activities and programs and, very particularly, it is interested in carrying out ecological restoration processes in some critical sites. The study area is located between 2000 and 2750 masl and is considered a low Andean humid forest (bmh-MB). The average annual precipitation rate is 2057 mm and the average temperature is around 11 ºC. The soil has a sandy loam texture with low pH, which limits the amount of nutrients it can absorb. FAO (2014) suggests that around 10 genera are enough for a proper restoration. After a bibliographic revision, the genera chosen were Alchornea, Billia, Ficus, Inga, Meriania, Miconia, Ocotea, Protium, Prunus, Psidium, Symplocos, Tibouchina, and Weinmannia. Two inventories from 2013 and 2019, helped to determine different biodiversity indexes to check the survival of different species and to suggest the adequate characteristics of the individuals for a successful vegetative stakes reforestation. -

Lamiales – Synoptical Classification Vers
Lamiales – Synoptical classification vers. 2.6.2 (in prog.) Updated: 12 April, 2016 A Synoptical Classification of the Lamiales Version 2.6.2 (This is a working document) Compiled by Richard Olmstead With the help of: D. Albach, P. Beardsley, D. Bedigian, B. Bremer, P. Cantino, J. Chau, J. L. Clark, B. Drew, P. Garnock- Jones, S. Grose (Heydler), R. Harley, H.-D. Ihlenfeldt, B. Li, L. Lohmann, S. Mathews, L. McDade, K. Müller, E. Norman, N. O’Leary, B. Oxelman, J. Reveal, R. Scotland, J. Smith, D. Tank, E. Tripp, S. Wagstaff, E. Wallander, A. Weber, A. Wolfe, A. Wortley, N. Young, M. Zjhra, and many others [estimated 25 families, 1041 genera, and ca. 21,878 species in Lamiales] The goal of this project is to produce a working infraordinal classification of the Lamiales to genus with information on distribution and species richness. All recognized taxa will be clades; adherence to Linnaean ranks is optional. Synonymy is very incomplete (comprehensive synonymy is not a goal of the project, but could be incorporated). Although I anticipate producing a publishable version of this classification at a future date, my near- term goal is to produce a web-accessible version, which will be available to the public and which will be updated regularly through input from systematists familiar with taxa within the Lamiales. For further information on the project and to provide information for future versions, please contact R. Olmstead via email at [email protected], or by regular mail at: Department of Biology, Box 355325, University of Washington, Seattle WA 98195, USA.
