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. -
Malpighiaceae De Colombia: Patrones De Distribución, Riqueza, Endemismo Y Diversidad Filogenética

C., Colombia; [email protected] (autor corresponsal). Abstract. Giraldo-Cañas, D. 2021. Malpighiaceae from Colombia: Patterns of distribution, richness, endemism, and phylogenetic diversity. Darwiniana, nueva serie 9(1): 39-54. Malpighiaceae constitutes a family of 77 genera and ca. 1300 species, distributed in tropical and subtropical regions of both hemispheres. They are mainly diversified in the American continent and distributed in a wide range of habitats and altitudinal gradients. For this reason, this family can be a model plant group to ecological and biogeographical analyses, as well as evolutive studies. In this context, an analysis of distribution, richness, endemism and phylogenetic diversity of Malpighiaceae in natural regions and their altitudinal gradients was undertaken. Malpighiaceae are represented in Colombia by 34 genera and 246 species (19.1% of endemism). Thus, Colombia and Brazil (44 genera, 584 species, 61% of endemism) are the two richest countries on species of this family. The highest species richness and endemism in Colombia is found in the lowlands (0-500 m a.s.l.: 212 species, 28 endemics); only ten species are distributed on highlands (2500-3200 m a.s.l.). Of the Malpighiaceae species in Colombia, Heteropterys leona and Stigmaphyllon bannisterioides have a disjunct amphi-Atlantic distribution, and six other species show intra-American disjunctions. -
Rubiaceae), and the Description of the New Species Galianthe Vasquezii from Peru and Colombia
Morphological and molecular data confirm the transfer of homostylous species in the typically distylous genus Galianthe (Rubiaceae), and the description of the new species Galianthe vasquezii from Peru and Colombia Javier Elias Florentín1, Andrea Alejandra Cabaña Fader1, Roberto Manuel Salas1, Steven Janssens2, Steven Dessein2 and Elsa Leonor Cabral1 1 Herbarium CTES, Instituto de Botánica del Nordeste, Corrientes, Argentina 2 Plant systematic, Botanic Garden Meise, Meise, Belgium ABSTRACT Galianthe (Rubiaceae) is a neotropical genus comprising 50 species divided into two subgenera, Galianthe subgen. Galianthe, with 39 species and Galianthe subgen. Ebelia, with 11 species. The diagnostic features of the genus are: usually erect habit with xylopodium, distylous flowers arranged in lax thyrsoid inflorescences, bifid stigmas, 2-carpellate and longitudinally dehiscent fruits, with dehiscent valves or indehiscent mericarps, plump seeds or complanate with a wing-like strophiole, and pollen with double reticulum, rarely with a simple reticulum. This study focused on two species that were originally described under Diodia due to the occurrence of fruits indehiscent mericarps: Diodia palustris and D. spicata. In the present study, classical taxonomy is combined with molecular analyses. As a result, we propose that both Diodia species belong to Galianthe subgen. Ebelia. The molecular position within Galianthe, based on ITS and ETS sequences, has been supported by the following morphological Submitted 10 June 2017 characters: thyrsoid, spiciform or cymoidal inflorescences, bifid stigmas, pollen grains Accepted 19 October 2017 with a double reticulum, and indehiscent mericarps. However, both species, unlike the Published 23 November 2017 remainder of the genus Galianthe, have homostylous flowers, so the presence of this Corresponding author type of flower significantly modifies the generic concept. -

OCCASIONAL PAPERS OF THE MUSEUM OF ZOOLOGY UNIVERSITY OF MICHIGAN ANNARBOR, MICIIIGAN THE SPHAERODACTYLUS (SAURIA: GEKKONIDAE) OF MIDDLE AMERICA INTRODUCTION Splzaerodactylus is one of the most speciose genera of gekkonid lizards. It is confined to the Neotropics, and the majority of its divers- ity is found in the West Indies where approximately 69 species, and an additional 74 subspecies, have been well-documented (King, 1962; Schwartz, 1964, 1966, 1968, 1977; Schwartz and Garrido, 1981; Schwartz and Graham, 1980; Schwartz and Thomas, 1964, 1975, 1983; Schwartz, Thomas, and Ober, 1978; Thomas, 1964, 1975; Thomas and Schwartz, 1966a,b). The mainland radiation was poorly understood until 1982 when Harris published his revision of South American sphaerodactyls. No comprehensive study has yet been at- tempted for Middle American forms, and it remains the last area of taxonomic confusion in the genus. The number of taxa currently recognized in Middle America is not great (10 species according to Peters and Donoso-Barros [1970], Schwartz [1973], and Smith and Taylor [1950b, 19661); however, their geographic distribution and variation, and status as species or subspecies remain to be con- vincingly demonstrated. The Middle American sphaerodactyl fauna appears to be divisible into two geographical-historical components. Most of the taxa may be thought of as belonging to an endemic group because the sister taxon *Division of Amphibians and Reptiles, Museum of Zoology, The University of Michi- gan, Ann Arbor, Michigan 48109-1079 U.S.A. 2 Harris and Kluge Orc.

Plant Structure in the Brazilian Neotropical Savannah Species
Chapter 16 Plant Structure in the Brazilian Neotropical Savannah Species Suzane Margaret Fank-de-Carvalho, Nádia Sílvia Somavilla, Maria Salete Marchioretto and Sônia Nair Báo Additional information is available at the end of the chapter http://dx.doi.org/10.5772/59066 1. Introduction This chapter presents a review of some important literature linking plant structure with function and/or as response to the environment in Brazilian neotropical savannah species, exemplifying mostly with Amaranthaceae and Melastomataceae and emphasizing the environment potential role in the development of such a structure. Brazil is recognized as the 17th country in megadiversity of plants, with 17,630 endemic species among a total of 31,162 Angiosperms [1]. The focus in the Brazilian Cerrado Biome (Brazilian Neotropical Savannah) species is justified because this Biome is recognized as a World Priority Hotspot for Conservation, with more than 7,000 plant species and around 4,400 endemic plants [2-3]. The Brazilian Cerrado Biome is a tropical savannah-like ecosystem that occupies about 2 millions of km² (from 3-24° Latitude S and from 41-43° Longitude W), with a hot, semi-humid seasonal climate formed by a dry winter (from May to September) and a rainy summer (from October to April) [4-8]. Cerrado has a large variety of landscapes, from tall savannah woodland to low open grassland with no woody plants and wetlands, as palm swamps, supporting the richest flora among the world’s savannahs-more than 7,000 native species of vascular plants- with high degree of endemism [3, 6]. The “cerrado” word is used to the typical vegetation, with grasses, herbs and 30-40% of woody plants [9-10] where trees and bushes display contorted trunk and branches with thick and fire-resistant bark, shiny coriaceous leaves and are usually recovered with dense indumentum [10]. -

Ruy José Válka Alves1 & Nílber Gonçalves da Silva 1 Recebido em 6/3/2011 – Aceito em 3/7/2011 RESUMO – Os campos rupestres ocupam menos de 3% das áreas de Cerrado e Caatinga, mas abrigam uma proporção significativa das espécies vegetais vasculares presentes nestes biomas. Embora várias adaptações ao fogo já tenham sido descritas para savanas do Brasil, ainda há carência de estudos sistemáticos do efeito do fogo nos campos rupestres. Este artigo visa comentar os efeitos combinados do fogo, gado e capim gordura na vegetação de campo rupestre. Palavras-chave: biodiversidade; cerrado; savana; fogo natural. ABSTRACT – Campo rupestre vegetation occupies less than 3% of the Brazilian Cerrado and Caatinga biomes, but it harbors a significant proportion of all vascular plant species present in these biomes. Even though many adaptations to fire have been described for plants from the Brazilian savannas, systematic surveys of the effects of fire on campo rupestre vegetation are still insufficient. In this paper we comment the combined effects of fire, cattle and molasses grass in campo rupestre vegetation. Keywords: biodiversity; cerrado; savanna; natural fire.
