Many features of flowers comprise the key elements of the pollinating strategies of flowering plants. Our aims were to describe features that attract pollinators and to identify the pollination system of Petunia interior, a species for which bees have been suggested as the probable pollinators. Therefore, we described the morphology and floral biology, assessed nectar production, concentration, and composition, examined reproductive mode and identified pollinators. P. interior has a purple, infundibuliform, zygomorphic corolla with a short and wide tube and blue pollen. Flower opening and pollen release were asynchronous throughout the day. The pollen grains have pollenkitt on the surface. The nectar sugar composition has a proportion of sucrose lower than the proportion of glucose + fructose, and the nectar supply was constant, in small amounts, at a concentration between 16.6-23.1 %. The reproductive system is xenogamous and bees were the exclusive pollinators. P. interior exhibits a set of floral traits that prevent self-pollination and maintains attractiveness to the bees. The greater reproductive success under natural conditions highlights the importance of bees for the reproductive success of P. interior. As far as floral traits are concerned, only the sugar concentration in the nectar does not correspond to melittophily.

During fieldwork in the Campos Amazônicos National Park, Amazonas state, Brazil, a new endemic species of Mabea was collected in savanna areas. Field collections and specimens in RON, MG, and HRCB were analyzed. To understand the species distribution and verify possible areas of occurrence, niche modeling was conducted using the sdm package in R. Mabea dalyana , the new species is a subshrub with xylopodia and reduced size (less than 1 m height) and small, yellow thyrses. There are several allopatric species of Mabea growing in Amazonian savannas, some widespread but others locally restricted, such as M. uleana from central Amazonia that has some superficial resemblance in leaves and inflorescences but can be distinguished from M. dalyana by pubescent adaxial leaf surface ( vs. glabrous), 12-21 submarginal glands ( vs. 10 submarginal glands), thyrse brownish to red ( vs. yellow thyrse) and conspicuous caruncle ( vs. caruncle inconspicuous). M. dalyana is endemic to hyperseasonal savanna, very well adapted to savanna, and fire tolerant. It has notable characteristics, such as a subshrub habit, a xylopodium, glabrous leaves, and sepals noticeably larger than the ovary.

Attalea speciosa (babassu) is a native palm of the primary forest from Amazonian and Cerrado biomes, and has multiple economic and cultural uses. However, this palm can become dominant in open areas, with a long-term persistence in the community. The objective of this study was to compare the population structure and morphology of babassu in three habitat types characterizing forest succession: primary forest, pasture, and babaçual (babassu-dominated secondary forest). For this purpose, we monitored 6,333 individuals for three years at six life stages in 11 sites with 25 plots located in PA-Benfica, Itupiranga-Pará, Brazil. The morphological parameters showed differences between secondary environments (pasture and babaçual) and primary forests, suggesting that this species has a high capacity for phenotypic plasticity. The inverse J-shaped distribution was observed only in primary forests, with the density of all stages constant along the whole study, unlike pastures and babaçual areas. While the density of seedlings is highest in primary forests, stage 4 and 5 juveniles and adults are most numerous in babaçuals. Our results suggest that the higher dominance of A. speciosa in babaçual areas can be associated with the resilience of this species to anthropogenic disturbances.

Climate change is expected to increase the occurrence of severe droughts in the tropics, and little is known about its influence on tree dynamics. Tree-ring width and remote sensing tools can help understand the impacts of climate change on tree growth. We evaluated the applicability of NDVI to obtain phenological metrics ( e.g. , start, peak, end, and length of growth season) and explored its relationship with tree-ring width of Tectona grandis (teak). The phenological metrics and tree-ring width were correlated with each other, and with both local (temperature, precipitation, solar insolation, Standardized Precipitation Evapotranspiration Index – SPEI) and large-scale (El Niño) climatic variables. The length of season and tree-ring width of teak were positively correlated with precipitation and negatively correlated with temperature in the initial months of the growth period. Tree-ring width was negatively correlated with El Niño events. Climate variables and length of season from the prior period were correlated with the tree-ring width of the current growing period. This study demonstrated that rather than directly affecting productivity, climate might also affect the length of the growing season, which would affect tree growth in the next season.

The Atlantic Forest is made up of different vegetation types over extensive latitude. Most of its remnants are in mountain ranges, which are responsible for the maintenance of most endemic and threatened species in this domain. Here we present the floristic composition of the Área de Proteção Ambiental Mestre Álvaro (APAMA), a coastal massif at Espírito Santo State with expressive altitudinal amplitude (100-800 a.s.l.) containing remnants never floristically studied. Knowing the composition of this protected area is important because it includes an altitudinal range not yet evaluated in floristic comparisons involving highland and lowland forests between the latitudes 18-21° S. We found 493 species (in 292 genera and 91 families): ten are regional endemic species, nine are new records of occurrence for the state, and 52 are under some degree of threat of extinction. Our results indicate the presence of flora elements’ typical of both highland and lowland forests, which makes the APAMA essential in a scenario extremely fragmented. Finally, our data provide an unprecedented floristic list for regional forest restoration projects, as well as an invaluable source of data for biogeographic studies that seek to understand the effect caused by neighboring vegetation types on the composition of lowland forests.
大西洋森林在广泛的纬度上由不同的植被类型组成。它的大部分遗迹都在山脉中，这些山脉负责维护该领域大多数特有和受威胁的物种。本文介绍了Área de prote o Ambiental Mestre Álvaro (APAMA)的植物区系组成，这是一个位于Espírito Santo State的沿海块体，具有明显的高度振幅(100-800 a.s.l.)，其中包含从未进行过植物区系研究的残留物。了解该保护区的组成是很重要的，因为它包括了一个尚未在纬度18-21°s之间的高原和低地森林植物区系比较中评估的海拔范围。我们发现了493种(隶属于91科292属):10种是区域特有物种，9种是该州的新记录，52种处于一定程度的灭绝威胁。我们的研究结果表明，高原和低地森林中都存在典型的植物区系元素，这使得APAMA在极度破碎的情景中必不可少。最后，我们的数据为区域森林恢复项目提供了前所未有的植物区系列表，也为寻求了解邻近植被类型对低地森林组成的影响的生物地理学研究提供了宝贵的数据来源。

Piper is a large genus in the Piperaceae family, with the subgenus Ottonia having about 30 species distributed in the Neotropics, most of which occur in Brazil (26 species). Ottonia is characterized by the flower densely papillate, pedicellate or sessile, with four stigmas, four stamens and 4-ribbed fruits with persistent stigmas. The recent global studies of Piper propose that all the species of Ottonia should be considered a subgenus of Piper . Beacause Brazil doesn’t have a revisionary study with the subgenus or with Piper , most of the names of the Piper subgenus Ottonia , about 100 names, need to be re-evaluated. We presented 26 species of Piper subgenus Ottonia , which one three are new species from Brazil Piper brumadinense M. Carv.-Silva & E.F. Guim., Piper cariacicaense M. Carv.-Silva & E.F. Guim., and Piper moringanum E.F. Guim. & M. Carv.-Silva. A synopsis of the Piper L. subgenus Ottonia Spreng. (Piperaceae) is presented, including diagnostics aspects and comments on species, descriptions of the new species, synonyms, lectotypes, and a key to the species and illustrations.
胡椒是胡椒科的一个大属，Ottonia亚属约有30种分布在新热带地区，其中大部分分布在巴西(26种)。其特征是花密生乳突，有花梗或无梗，具四柱头，四雄蕊和四棱果，具宿存柱头。最近的全球研究表明，奥托尼亚的所有种都应该被认为是Piper的一个亚属。因为巴西没有对Piper亚属或Piper亚属的修订研究，所以大多数Piper亚属的名字，大约100个名字，需要重新评估。本文报道了26种鹬亚属(Ottonia)，其中1 - 3种为巴西鹬亚属新种。——席尔瓦和E.F.圭姆，派珀·卡西卡森·m·卡夫。——席尔瓦和E.F.圭姆以及moringanum E.F.
