“…It is native to South America, and is found mainly in Brazil, Argentina and Paraguay (Pereira et al, 2014). In Brazil, it is commonly found in the South and Southeast, as well as in the states of Bahia (Northeast) and Goiás (Central Brazil) (Pedralli et al, 1997;Lorenzi, 2009). On the Espinhaço Mountain Range, which extends throughout the states of Minas Gerais and Bahia, E. erythropappus is distributed across the entire altitudinal gradient, occupying high regions, rocky outcrops and riparian forests (Carneiro et al, 2009b).…”

The role of Senescent Stem-Galls over Arboreal Ant Communities Structure in Eremanthus erythropappus (DC.) MacLeish (Asteraceae) Trees

2017

The extensive occupation of canopy trees by ants can be attributed to many factors, such as the presence of structures that provide food and shelter. Structures induced by other insects in host plants, like senescent galls, can provide shelter and a nesting place for many species of ants. The main objectives of this work were: (1) to describe the ant communities found in canopies of candeia trees (Eremanthus erythropappus), including the species which use galls as nesting sites; (2) verify the role of galls in determining the structure and composition of the ant communities and (3) to evaluate whether the size and shape of galls are important to the choice of nesting sites by ants. Specifically, the following questions were investigated: 1 – Are larger galls more frequently occupied by ants than smaller galls? 2 – Does gall shape (globular and fusiform) influence occupation? 3 – Which species of ants are present in the canopies of candeias and which are occupying galls? Senescent galls were collected in locations in the southern portion of the Espinhaço Mountain Range, state of Minas Gerais, southeastern Brazil. In total, 3,195 galls were collected and 19 ant species were recorded. Only 176 galls (5.5%) had been occupied by ants, and these were represented by 11 species. The most frequent species found occupying galls were Myrmelachista nodigera, with 48 colonies; Nesomyrmex spininodis, with 37 colonies; and Crematogaster complex crinosa sp. 1, with 29 colonies. The ants occupied galls with greater volume and diameter. Even considering the low occupation frequency, senescent galls in E. erythropappus are used by ants, either as outstations or satellite nests of polydomic colonies, and may be important in determining ant species composition in canopy trees.

As Leguminosae arbóreas das florestas estacionais do Parque Estadual do Itacolomi, Minas Gerais, Brasil

2010

ResumoEste estudo consiste do tratamento taxonômico das Leguminosae arbóreas das florestas estacionais do Parque Estadual do Itacolomi (PEI). As coletas de material botânico ocorreram mensalmente, entre setembro de 2004 e novembro de 2005, ao longo de oito trilhas distribuídas em áreas de florestas estacionais submontana, montana e altimontana. O levantamento resultou em 39 táxons reunidos em 22 gêneros e distribuídos entre as três subfamílias: Caesalpinioideae (9 espécies), Mimosoideae (17) e Papilionoideae (13). Os gêneros mais representativos foram Inga (8 espécies), Machaerium (4), Senna e Dalbergia (3, cada), Abarema, Anadenanthera e Tachigali (2, cada). Bauhinia, Cassia, Copaifera, Melanoxylon, Calliandra, Mimosa, Piptadenia, Pseudopiptadenia, Stryphnodendron, Andira, Bowdichia, Ormosia, Platypodium, Pterocarpus e Swartzia apresentaram uma espécie cada. Ormosia friburgensis e Tachigali friburgensis são registradas pela primeira vez para o estado de Minas Gerais. São fornecidos chave de identificação, descrições, ilustrações, dados fenológicos, comentários taxonômicos e preferência por habitats de cada táxon no PEI. Palavras-chave: Fabaceae, leguminosas, Mata Atlântica, taxonomia. Abstract This study presents the taxonomic treatment of woody Leguminosae in seasonal forests of Itacolomi State Park (PEI). Botanical material was collected monthly, from September 2004 to November 2005, along eight trails in submontane, montane and upper montane seasonal forests. Woody Leguminosae were represented by 39 taxa in 22 genera distributed among the three subfamilies: Cesalpinioideae (9 species), Mimosoideae (17), and Papilionoideae (13). The most representative genera were Inga (8 species), followed by Machaerium (4), Senna and Dalbergia (3 each), Abarema, Anadenanthera, and Tachigali (2 each). Bauhinia, Cassia, Copaifera, Melanoxylon, Calliandra, Mimosa, Piptadenia, Pseudopiptadenia, Stryphnodendron, Andira, Bowdichia, Ormosia, Platypodium, Pterocarpus, and Swartzia were represented by one species each. Ormosia friburgensis and Tachigali friburgensis are reported for the first time in Minas Gerais state. Analytical key, descriptions, illustrations, data on phenology, and comments on taxonomy and preferred habitat in PEI are provided for all taxa.

“…No entanto, essa facilidade em colonizar áreas abertas, clareiras ou bordas de fragmento, pode levar algumas famílias como Asteraceae, Poaceae, Solanaceae e Melastomataceae a serem apontadas como grupos indicadores de ambientes alterados (Teixeira e Mantovani, 1998;Tabarelli e Mantovani, 1999). Pedralli et al (1997) relacionaram a riqueza de Asteraceae às espécies herbáceas invasoras, por terem facilidade de propagação e por indicarem estádios iniciais de sucessão devido à rapidez na colonização das áreas.…”

ResumoCom o objetivo de caracterizar a composição florística do sub-bosque, o presente estudo foi desenvolvido no Parque Estadual de Dois Irmãos, (08°01'15,1"S e 34°56'3,2"W -sede), com área de aproximadamente 370ha, caracterizado como Floresta Ombrófila Densa das Terras Baixas, em que foram incluídos indivíduos de até 4,0m de altura, como arvoretas, arbusto, sub-arbustos e herbáceas terrícolas, em estádio fértil. As coletas quinzenais foram realizadas por um período de 24 meses. Foram coletadas 108 espécies, distribuídas em 86 gêneros e 49 famílias. As famílias com maior número de espécies foram Rubiaceae (14), Fabaceae (9), Melastomataceae (8), Asteraceae (8), Myrtaceae (6) e Poaceae (4). Fabaceae, Melastomataceae, Myrtaceae e Rubiaceae destacaram-se pelo maior número de espécies encontradas no sub-bosque do fragmento. De maneira geral, entre os levantamentos realizados em áreas de floresta atlântica de Pernambuco, constata-se a presença de um conjunto de espécies arbóreas comuns a essas florestas.Unitermos: fragmento urbano, Pernambuco, riqueza, sub-bosque AbstractUnderstory species richness in an urban forest fragment, Pernambuco, Brazil. This study characterizes the floristic composition of the understory of Parque Estadual de Dois Irmãos, (08°01'15.1"S and 34°56'3.2"W), an area of about 370ha characterized as a lowland ombrophilous dense forest. The study included individuals with heights of up to 4.0m, such as treelets, shrubs, sub-bushes and terricolous herb plants, in fertile conditions. The collections were made every two weeks along a period of 24 months. A total of 108 species, belonging to 86 genera and 49 families, were recorded. The families with the highest number of species were Rubiaceae (14), Fabaceae (9) Melastomataceae (8), Asteraceae (8), Myrtaceae (6), and Poaceae (4). The Fabaceae, Melastomataceae, Myrtaceae and Rubiaceae presented the highest number of understory species in this fragment. Generally, among the studies made in the Atlantic forest areas in Pernambuco, the presence of a set of tree species common to these forests is evidenced.
