Phenological synchrony and seasonality of understory Rubiaceae in the Atlantic Forest, Bahia, Brazil
Provedor de dados: 39
Autores: Liuth,Heitor Scarpati; Talora,Daniela Custódio; Amorim,André Márcio.
In tropical forests with low seasonality, climatic variables generally exert a weak influence on the phenology of species. The seasonality of phenophases in closely related taxa can be controlled by phylogenetic constraints in such environments. In this study, our aim was to describe the phenology of Rubiaceae in the understory of the Atlantic Forest in the southern part of Bahia, Brazil, as well as to evaluate the seasonality and phenological synchrony of this family. For two years, we observed 90 individuals belonging to 13 species, in an area of 0.2 ha. Leaf flushing and leaf fall did not demonstrate any seasonality, were continuous for most species and correlated with few of the climatic variables. Flowering was seasonal and correlated positively with...

Pollen morphology of Menispermaceae in the state of Bahia, Brazil
Provedor de dados: 39
Autores: Teixeira,Michella Del Rei; Amorim,André Márcio; Santos,Francisco de Assis Ribeiro dos.
There have been few palynological studies of the family Menispermaceae. Here, we analyzed the pollen grains of 12 species from seven genera of Menispermaceae occurring in the state of Bahia, Brazil: Abuta selloana Eichl.; Borismene japurensis (Mart.) Eichl.; Chondrodendron microphyllum (Eichl.) Moldenke; C. platyphyllum (A.St.-Hil.) Miers; Cissampelos andromorpha DC.; C. ovalifolia DC.; C. pareira L.; C. sympodialis Eichl.; Hyperbaena domingensis (DC.) Benth.; Odontocarya duckei Barneby; Sciadotenia campestris Barneby; and S. pubistaminea (K. Schum.) Diels. The pollen grains were acetolysed, measured, described, and illustrated using light and scanning electron microscopy. The pollen grains were found to be small, oblate spheroidal or prolate spheroidal,...

Demographic structure of a threatened palm (Euterpe edulis Mart.) in a fragmented landscape of Atlantic Forest in northeastern Brazil
Provedor de dados: 39
Autores: Melito,Melina Oliveira; Faria,José Cláudio; Amorim,André Márcio; Cazetta,Eliana.
At the northern limits of the range of the palm species Euterpe edulis there is an endemic ecotype, known as the "Bahia" ecotype, which is distinguished by its reddish crownshaft and low seed production. Unfortunately, little is known about its demographic characteristics. Therefore, we contrasted the density of E. edulis populations in the Una region, in the southern part of the Bahia state, Brazil, with that of other populations of the species in southern and southeastern Brazil. In addition, within the Una region, we compared a long-protected forest fragment (F1) with three recently protected fragments (F2, F3, and F4), in terms of demographic parameters and plant size, in order to determine what influence, if any, time since protection has on E. edulis...

Endemic angiosperms in Bahia Coastal Forests, Brazil: an update using a newly delimited area
Provedor de dados: 49
Autores: Ostroski,Piera; Saiter,Felipe Zamborlini; Amorim,André Márcio; Fiaschi,Pedro.
Abstract: The forest along the coast of Bahia state, in northeastern Brazil, has been acknowledged as an area of endemism for several groups of organisms. The first study concerning endemic angiosperm species in this region, through which 395 taxa were registered, was conducted 15 years ago. However, this number is probably underrated. In this article, we present an updated checklist of angiosperm taxa in Bahia Coastal Forests (BCF) based on geographic distribution data available from the Brazilian Plant List (Flora do Brasil 2020). The records were checked in herbaria, recent taxonomic literature, and, when necessary, reviewed by experts. The final checklist consists of 547 taxa endemic to BCF, distributed in 69 families, with seven endemic genera:...

Autores: Santos,Jéssica Vieira dos; Amorim,André Márcio; Conceição,Adilva de Souza.
Abstract This study presents a floristic survey of Malpighiaceae species from in the Raso da Catarina Ecoregion in the state of Bahia, Brazil. After extensive field and herbarium studies, we identified 18 genera and 32 species of Malpighiaceae in the study area: Aspicarpa harleyi W.R.Anderson, Banisteriopsis C.B.Rob. (3 spp.), Barnebya harleyi W.R.Anderson &amp; B.Gates, Bronwenia ferruginea (Cav.)

Angiospermas em remanescentes de floresta montana no sul da Bahia, Brasil
Provedor de dados: 49
Autores: Amorim,André Márcio; Jardim,Jomar Gomes; Lopes,Márdel Miranda Mendes; Fiaschi,Pedro; Borges,Rafael Augusto Xavier; Perdiz,Ricardo de Oliveira; Thomas,William Wayt.
Foi realizado um levantamento florístico de três remanescentes de floresta montana localizados na Mata Atlântica do sul da Bahia. Durante os anos de 2004 a 2008 foram feitas coletas periódicas de material botânico, principalmente ao longo de trilhas no interior dos fragmentos das áreas: Reserva Serra da Pedra Lascada - SPL, Reserva Serra das Lontras - SLO e Reserva Particular do Patrimônio Natural Serra Bonita - SBO. A riqueza florística em cada área foi comparada entre si e com outras áreas de Mata Atlântica na Bahia e no Sudeste do Brasil. Foi registrado um total de 1.129 espécies em 467 gêneros e 124 famílias. O hábito arbóreo representou 46,9% das espécies, seguido de herbáceas (20,1%), epífitas (19,5%) e trepadeiras (13,5%). As famílias Araceae,...

Floristic composition of the Montane Forest in the Almadina-Barro Preto axis, Southern Bahia, Brazil
Provedor de dados: 49
Autores: Coelho,Macielle Macedo; Amorim,André Márcio.
The aim of this study is to survey the angiosperms of two montane forest remnants in the southern Bahia, Brazil: Corcovado (SCO) and Pedra Lascada (SPL). Both fragments are located in the municipality of Almadina and Barro Preto, respectively, and are 18 km distant from each other. We sampled 899 species of angiosperms distributed in 437 genera and 116 families. The SCO was the richest area with 678 species, distributed in 367 genera and 100 families. SPL showed 466 species in 269 genera and 88 families. The percentage of species identified was 85.8% and of this total, 37.7% are endemic to the Atlantic Forest, 11.2% are endemic to southern Bahia and northern Espírito Santo and 7% are disjunct between the Atlantic Forest and Amazon. The remaining...
