Climatic niche shift after range expansion of Eustachys (Poaceae).

Eustachys presents lower diversity in the Old World than in the Neotropics and it occurs disjunctly between main tropical regions. This qualifies Eustachys as a good model to test whether lineages expand their niches during the process of range expansion. We performed ancestral range reconstruction, compared environmental spaces of the different geographic areas and assessed bioclimatic trait evolution. Ancestral range reconstruction indicated that most speciation in Eustachys occurred in the South America. Ancestral climatic niches of the New World are different from those of African and Australasia lineages. Our results show that Eustachys experienced niche expansion when it reached the New World. Evolutionary history of Eustachys illustrates how the range expansion promoted climatic niche shifts, which could drive unbalanced species richness of the genus among different tropical regions.

Genetic diversity and population structure of two Euglossini bee species in a host-parasite relationship.

In the current study, two euglossine species, Exaerete smaragdina and Eulaema nigrita, a cleptoparasite bee and its host, respectively, were used as models to: (i) access the genetic diversity and population structure of both species, sampled along a wide latitudinal range of Atlantic Forest, where the distribution of El. nigrita and Ex. smaragdina co-occurs; (ii) investigate the evolutionary history of these species through the Atlantic Forest, and in a wider scenario, to examine the evolutionary history of these species across others forest domains. Analyses involved males of El. nigrita and Ex. smaragdina sampled through Brazilian territory, including 19 sites in the Atlantic Forest. Bayesian Skyline Plot (BSP) was used to infer possible climate oscillations on population of both species over time. The BSP revealed stability in effective population size for both species in most of the Plio-Pleistocene period. However, BSP results aligned to the starlike configuration in the haplotype network, neutrality test, and population diversity patterns indicated population expansion of the two species during the late Pleistocene. Our findings suggest areas of potential refugia to the climatic oscillations of the Pleistocene in the Atlantic Forest in the Brazilian states of Espírito Santo for El. nigrita and Pernambuco for Ex. smaragdina.

Amazonian Melastomataceae blueberries: Determination of phenolic content, nutritional composition, and antioxidant and anti-glycation activities.

Berries come from hundreds of different species of plants spread around the world. Blackberries, blueberries and raspberries, for instance, are popular berries that have attracted attention for providing several benefits to human health. Wild berries from the Melastomataceae family are commonly encountered in the Amazon, although these small blue fruits are poorly consumed. Although domesticated fruits give better monetary profits, the consumption of wild fruits is a desirable option to afford income and/or food to communities at the same time as keep the Amazon region preserved. Aiming the divulgation of the nutritional potential of these plants, this paper describes the study of six species of Amazonian blueberries, five of them from the Clidemia genus and one from the Tococa genus, in regard to their nutritional and chemical composition and antioxidant activity (AA). The levels of moisture, ash, protein, lipids, carbohydrates, and the total caloric values obtained for the Amazonian blueberries were comparable to other common edible berries. Although the six species are similar in terms of nutritional composition, their anthocyanin profiles and contents are quite peculiar. Two non-methylated anthocyanins, cyanidin and delphinidin, which bound to a variable number of sugars, characterized the berries of the genera Clidemia and Tococa. Clidemia japurensis, Clidemia hirta and Tococa bullifera were rich in tri-glycosylated anthocyanins, although differences are notable between them. Clidemia pustulata and Clidemia capitellata were characterized by the prevalence of mono-glycosylated anthocyanins, and Clidemia rubra showed a unique profile with mono- and di-glycosylated homologous as the main anthocyanins. In addition to their different chemical profiles, the concentrations of anthocyanins and other phenolic compounds varied a lot among the six species studied. The species C. rubra had the highest total concentration of phenolic acids and flavonoids. Therefore, this study showed that the blueberries analyzed have potential to be better explored, which we suggest doing in a sustainable way, aiming at the preservation of the Amazon's biodiversity.

Data standardization of plant-pollinator interactions.

BACKGROUND: Animal pollination is an important ecosystem function and service, ensuring both the integrity of natural systems and human well-being. Although many knowledge shortfalls remain, some high-quality data sets on biological interactions are now available. The development and adoption of standards for biodiversity data and metadata has promoted great advances in biological data sharing and aggregation, supporting large-scale studies and science-based public policies. However, these standards are currently not suitable to fully support interaction data sharing. RESULTS: Here we present a vocabulary of terms and a data model for sharing plant-pollinator interactions data based on the Darwin Core standard. The vocabulary introduces 48 new terms targeting several aspects of plant-pollinator interactions and can be used to capture information from different approaches and scales. Additionally, we provide solutions for data serialization using RDF, XML, and DwC-Archives and recommendations of existing controlled vocabularies for some of the terms. Our contribution supports open access to standardized data on plant-pollinator interactions. CONCLUSIONS: The adoption of the vocabulary would facilitate data sharing to support studies ranging from the spatial and temporal distribution of interactions to the taxonomic, phenological, functional, and phylogenetic aspects of plant-pollinator interactions. We expect to fill data and knowledge gaps, thus further enabling scientific research on the ecology and evolution of plant-pollinator communities, biodiversity conservation, ecosystem services, and the development of public policies. The proposed data model is flexible and can be adapted for sharing other types of interactions data by developing discipline-specific vocabularies of terms.

Essential Oil from Bark of Aniba parviflora (Meisn.) Mez (Lauraceae) Reduces HepG2 Cell Proliferation and Inhibits Tumor Development in a Xenograft Model.

Aniba parviflora (Meisn.) Mez (Lauraceae) is an aromatic plant of the Amazon rainforest, which has a tremendous commercial value in the perfumery industry; it is popularly used as flavoring sachets and aromatic baths. In Brazilian folk medicine, A. parviflora is used to treat victims of snakebites. Herein, we analyzed the chemical composition of A. parviflora bark essential oil (EO) and its effect on the growth of human hepatocellular carcinoma HepG2 cells in vitro and in vivo. EO was obtained by hydrodistillation and characterized by GC-MS and GC-FID. The main constituents of EO were linalool (16.3±3.15), α-humulene (14.5±2.41 %), δ-cadinene (10.2±1.09 %), α-copaene (9.51±1.12 %) and germacrene B (7.58±2.15 %). Initially, EO's cytotoxic effect was evaluated against five cancer cell lines (HepG2, MCF-7, HCT116, HL-60 and B16-F10) and one non-cancerous one (MRC-5), using the Alamar blue method after 72 h of treatment. The calculated IC50 values were 9.05, 22.04, >50, 15.36, 17.57, and 30.46 µg/mL, respectively. The best selectivity was for HepG2 cells with a selective index of 3.4. DNA Fragmentation and cell cycle distribution were quantified in HepG2 cells by flow cytometry after a treatment period of 24 and 48 h. The effect of EO on tumor development in vivo was evaluated in a xenograft model using C.B-17 SCID mice engrafted with HepG2 cells. In vivo tumor growth inhibition of HepG2 xenograft at the doses of 40 and 80 mg/kg were 12.1 and 62.4 %, respectively.

Nesting habits of Centris (Hemisiella) dichrootricha (Hymenoptera: Apidae) in the Northern Cerrado of Brazil / Hábito de nidificación de Centris (Hemisiella) dichrootricha (Hymenoptera: Apidae) en el Cerrado Norte de Brasil

Abstract:The Neotropical bee Centris (Hemisiella) dichrootricha is a solitary bee that nests in pre-existing cavities that occur in the rain forest. This study describes the nesting biology of C. dichrootricha and its preference for nesting in Cerrado and gallery forest habitats. The study was conducted from January 2012 and December 2013, in Mirador State Park in the municipality of Formosa da Serra Negra, Maranhão State, Brazil. For this, wooden trap-nests of 6, 8, 10, 12, 14 and 16 mm in diameter were used; a total of 300 trap-nests were placed in the gallery forest and Cerrado areas, respectively. Traps were monitored monthly and all completed nests were collected and replaced with empty ones. The nests were then taken to the laboratory to analyze bee development and emergence, nests characteristics and parasites presence. The species used 29 of the trap-nests, which had diameters of 8, 10, 12 and 14 mm. A total of 87 C. dichrootricha specimens emerged. The nests were parasitized by two bee species, Mesocheira bicolor (Apinae) and Coelioxys sp. (Megachilinae), and one fly species, Antrax sp. (Diptera). The highest nesting incidence of 72.4 % was observed in the gallery forest, whereas only 27.6 % in the Cerrado; this difference in habitat use was significant (χ² = 5.56; p < 0.05; DF = 1). For the nests that were built in the gallery forest, 80.9% of the soil originated from the Cerrado. The females were significantly larger than the males (F1, 76 = 595.19; p < 0.001). There were 11 pollen types that belonged to six families. Pollen of the family Malpighiaceae was most frequently used, with four species represented (Byrsonima crassifolia, B. rotunda, B. spicata and Heteropterys sp.). C. dichrootricha showed a preference for nesting in cavities of various diameters in gallery forest sites. The present study provides a novel description of the nesting habits and biology of C. dichrootricha in habitats of Central/Southern Maranhão. C. dichrootricha primarily used resources from the Cerrado, including soil to build their nests, pollen and floral oils; we concluded that gallery forest and Cerrado areas are intrinsically related to the maintenance of local populations of this species.

ResumenCentris (Hemisiella) dichrootricha es una especie de abeja solitaria neotropical, que anida en cavidades preexistentes y vive en la selva tropical. El presente estudio describe la biología de anidación de C. dichrootricha y su preferencia de nidificación por áreas en Cerrado y Bosque de Galería. El área de estudio se localiza en el Parque Estadual de Mirador, municipio de Formosa da Serra Negra, Maranhão. El método empleado fue el de nidos trampa de madera de diferentes diámetros, 6, 8, 10, 12, 14 y 16 mm, colocándose 300 nidos trampa por área. Las trampas fueron monitoreadas mensualmente y todos los nidos terminados fueron recogidos y sustituidos por otros vacíos. Los nidos completos fueron llevados al laboratorio para analizar el desarrollo de la abeja, la emergencia, las características de los nidos y la presencia de parásitos. La especie ocupó 29 nidos de los diámetros de 8, 10, 12 y 14 mm. Emergieron 87 individuos de C. dichrootricha. Los nidos fueron parasitados por tres especies: Mesocheira bicolor (Apinae), Coelioxys sp. (Megachilinae) y Antrax sp. (Diptera). En el Bosque de Galería se presentó la mayor nidificación (72.4 %) y en el Cerrado solamente 27.6 %, de esta forma, hubo diferencias significativas entre los hábitats (χ² = 5.56; p < 0.05; G. L.= 1). Los nidos fundados en el bosque de galería presentaron 80.9 % de sedimento originario del Cerrado. Las hembras fueron significativamente más grandes que los machos (F1, 76 = 595.19; p < 0.001). Hubo 11 tipos de polen pertenecientes a seis familias. Los tipos de polinización de la familia Malpighiaceae fueron los más representativos, con cuatro especies: Byrsonima crassifolia, B. rotunda, B. spicata y Heteropterys sp. C. dichrootricha mostró preferencia por nidificar en cavidades con diámetros variados y en el bosque de galería. El presente estudio contribuye con la descripción de los hábitos de nidificación y la biología de la especie para las áreas de Cerrado en la región centrosur de Maranhão. C. dichrootricha utilizó en su mayoría recursos provenientes del Cerrado, tanto sedimento para construir el nido, como material polínico y aceite floral. Estós datos indican que el bosque de galería y el Cerrado están intrínsecamente relacionados con el mantenimiento y conservación de C. dichrootricha.

Comunidade de abelhas (Hymenoptera, Apoidea) em ecossistema de dunas na Praia de Panaquatira, São José de Ribamar, Maranhão, Brasil / Community of bees (Hymenoptera, Apoidea) in the coastal sand dunes at Panaquatira beach, São José de Ribamar, Maranhão, Brazil

Comunidade de abelhas (Hymenoptera, Apoidea) em ecossistema de dunas na Praia de Panaquatira, São José de Ribamar, Maranhão, Brasil. Foi analisada a estrutura da comunidade de Apoidea de uma área restrita de dunas primárias em São José de Ribamar, Maranhão, Brasil. Amostragens foram realizadas quinzenalmente durante um ano com metodologia padronizada totalizando 24 coletas. As coletas ocorreram no período das 12:00 às 18:00 h no primeiro dia e das 6:00 às 12:00 h no segundo, realizadas por dois coletores. Um total de 3305 indivíduos de 31 espécies pertencentes a quatro famílias (Apidae>Halictidae>Megachilidae>Andrenidae em número de indivíduos) foram coletadas nas flores. Centris com 14 espécies e 890 indivíduos foi o gênero mais rico e abundante. O padrão de abundância e riqueza foi bastante semelhante ao de outros habitats de dunas no nordeste brasileiro. Das espécies amostradas, 61 por cento foram representadas por menos de 36 indivíduos e apenas 5 espécies foram muito abundantes com mais de 177 indivíduos: Apis mellifera Linnaeus, Centris (Centris) leprieuri Spinola, Eulaema (Apeulema) nigrita Lepeletier, Eufriesea surinamensis Linnaeus e Xylocopa (Neoxylocopa) cearensis Ducke. As abelhas estiveram presentes durante todo o ano, apresentando picos de abundância no período de maior precipitação. A atividade diária foi maior entre 06:00 e 11:00 h, quando a temperatura aumentava e a umidade relativa decrescia.

The community structure of Apoidea of a restricted area of primary dunes in São José de Ribamar, Maranhão, Brazil was analyzed. Standardized samples were taken for one year, 2 times a month, from 12:00 a.m. to 6:00 p.m. on the first day and from 6:00 a.m. to 12:00 a.m. on the second by two collectors. A total of 3305 individuals of 31 species, belonging to four families (Apidae > Halictidae > Megachilidae > Andrenidae) were collected. Centris with 14 species and 890 individuals was the richest and most abundant genus. The abundance pattern and the richness were very similar to other sand dunes habitats in northeast Brazil. Of the total of bees sampled, 61 percent were represented by less than 36 individuals. The five most abundant species (more than 177 individuals) were: Apis mellifera Linnaeus, Centris (Centris) leprieuri Spinola, Eulaema nigrita Lepeletier, Eufriesea surinamensis Linnaeus and Xylocopa (Neoxylocopa) cearensis Ducke. Bees were active throughout the year, with abundance peaks in the highest rainfall periods. Daily activity was greatest between 06:00 and 11:00 a.m., when relative humidity decreased and the temperature increased.

[Euglossina bees (Hymenoptera: Apidae) in an area with sandbanks in the northeast of the state of Maranhão, Brazil]. / Abelhas Euglossina (Hymenoptera: Apidae) em área de restinga do nordeste do Maranhão.

The bees of subtribe Euglossina are an important component of neotropical fauna and have greater species diversity in tropical forests than in spits. They play an important role in the pollination of several plant species and are considered good indicators of environmental conditions. From February 2005 to January 2006, a total of 429 specimens belonging to three genera [Euglossa (Latreille), Eulaema (Lepeletier) and Eufriesea (Cockerell)] and 14 species were collected. Eulaema cingulata (Fabricius) (24.5%), Euglossa cordata (L.) (20.5%) and Eufriesea nigrescens (Friese) (19.8%) were the most abundant species, representing 64.8% of all bees collected. Rainfall was the environmental variable with the greatest relative influence on species composition, particularly for some species of Eufriesea. Euglossa cordata and Eg. gaianii Dressler nested in trap nests, suggesting they are resident species. The larger number of individuals and greater richness of species compared with data available in the literature may result from the great variety of plant species found in the areas adjacent to the collection site.

As abelhas da subtribo Euglossina são importantes elementos da fauna neotropical, ocorrendo em maior diversidade em floresta tropical que em área de restinga. Essas abelhas são responsáveis pela polinização de inúmeras espécies de plantas, sendo consideradas boas indicadoras das condições ambientais. De fevereiro/2005 a janeiro/2006 foram coletados 429 indivíduos pertencentes a três gêneros [Euglossa (Latreille), Eulaema (Lepeletier) e Eufriesea (Cockerell)] e 14 espécies. As espécies mais frequentes foram Eulaema cingulata (Fabricius) (24,5 por cento), Euglossa cordata (L.) (20,5 por cento) e Eufriesea nigrescens (Friese) (19,8 por cento), constituindo 64,8 por cento dos indivíduos. Pluviosidade foi a variável ambiental que teve maior importância relativa sobre a variação da composição de espécies, pelo menos para algumas espécies de Eufriesea. Eg. cordata e Eg. gaianii Dressler nidifi caram em ninhos armadilhas colocados na área, o que sugere que são espécies residentes. A grande abundância e riqueza de espécies, quando comparadas a outros trabalhos, podem ser devidas ao mosaico de distintas formações vegetais encontrado nas áreas adjacentes ao sítio específico de coleta.

Apple pomace: a versatile substrate for biotechnological applications.

Apple pomace is the processing waste generated after apple juice manufacturing and represents up to 30% of the original fruit. This solid residue consists of a complex mixture of peel, core, seed, calyx, stem, and soft tissue. This residual material is a poor animal feed supplement because of its extremely low protein content and high amount of sugar. The application of agroindustrial by-products in bioprocesses offers a wide range of alternative substrates, thus helping solve pollution problems related to their disposal. Attempts have been made to use apple pomace to generate several value-added products, such as enzymes, single cell protein, aroma compounds, ethanol, organic acids, polysaccharides, and mushrooms. This article reviews recent developments regarding processes and products that employed apple pomace as a substrate for biotechnological applications.

The Centridini has almost 176 species distributed mainly in the tropic regions of America. Although they are considered key pollinators in the maintenance of many vegetal species, data about their bionomics are restrict. Nesting activity is known for 11 species, out of the 21 that are considered pollinators of murici, Byrsonima crassifolia L. Kunth, a valuable biomonitoring specie. A study of the nesting biology of Centris flavifrons (Friese) was conducted in the state of Maranhão, Brazil, during the active period of the adults (May through December). Nests were aggregated. The females excavated their nests on flat surfaces of hard soils. Fifteen nests were dug and we only found cells in six of them. The nests architecture consisted of a single unbranched tunnel, with only one cell in the vertical position at the end, which was 25 cm to 50 cm away from the entrance. Nocturnal activity was observed in the nests building. The pollen analysis of the contents of four cells allowed to identify 23 floral species, six of them Malpighiaceae. Six floral species were registered visiting C. flavifrons by the first time: Lecythis lurida (Miers) Mori, Hymenea courbaril L., Myrcea sp., Protium sp., Tetrapterys sp. and Thalisia sp.
