Resource‐related variables drive individual variation in flowering phenology and mediate population‐level flowering responses to climate in an asynchronously reproducing palm

AbstractMany tropical plant species show wide intra‐population variation in reproductive timing, resulting in the protracted presence of flowering and fruiting individuals. Various eco‐evolutionary drivers have been proposed as ultimate causes for asynchronous phenology, yet little is known about the proximate factors that control reproductive onset among individuals or that influence the proportion of trees producing new inflorescences within a population. We employed a nine‐year phenological record from 178 individuals of the hyperdominant, asynchronously flowering canopy palm, Oenocarpus bataua (Arecaceae)¸ to assess whether resource‐related variables influence individual‐ and population‐level flowering phenology. Among individuals, access to sunlight increased rates of inflorescence production, while the presence of resource sinks related to current investment in reproduction—developing infructescences—reduced the probability of producing new inflorescences. At the population level, climate anomalies induced by El Niño Southern Oscillation (ENSO) affected the proportion of the population producing inflorescences through time. Moreover, the effects of ENSO anomalies on flowering patterns depended on the prevalence of developing infructescences in the population, with stronger effects in periods of low developing‐infructescence frequency. Taken together, these results suggest that resource‐related variables can drive phenological differences among individuals and mediate population‐level responses to larger‐scale variables, such as climate anomalies. Consequently, a greater focus on the role of resource levels as endogenous cues for reproduction might help explain the frequent aseasonal phenological patterns observed among tropical plants, particularly those showing high intra‐population asynchrony.Abstract in Spanish is available with online material.

Evaluation of quality parameters and chromatographic, spectroscopic, and thermogravimetric profile of Patauá oil (Oenocarpus bataua)

Abstract The objective of this research was to evaluate the quality parameters and the chromatographic, thermogravimetric, and spectroscopic profile of Pataua oil (Oenocarpus bataua). All analyses were performed according to the Recommended Practices of the American Oil Chemists’ Society (AOCS). The parameters obtained indicate conservation quality standards in accordance with Brazilian legislation. The fatty acid profile shows a predominance of ω-9, ω-6, and ω-3 fatty acids. The thermogravimetric behavior and differential analysis indicated good stability upon gradual temperature increase and the presence of endothermic and exothermic peaks characteristic of thermal and oxidative decomposition at high temperatures only. The spectroscopic profile evidenced long-chain unsaturated fatty acids confirming the fatty acid profile results. It was found that, in general, the Pataua oil has good nutritional and functional quality and high thermal and oxidative stability; therefore it can be considered as a raw material with potential applications in various industries.

Mineralogical Composition and Bioactive Molecules in the Pulp and Seed of Patauá (Oenocarpus bataua Mart.): A Palm from the Amazon

The Patauá (Oenocarpus bataua Mart.) also known as Bataua or Patuá, is a palm native from the Amazon, consumed among the local populations as well as the wine obtained from its pulp with high energy value. It is a monocle palm tree reaching between 4-26 meters tall, distributed in the Amazon rainforest both in the wet forest of floodplains. The objective of this work was to study the proximal, mineralogical composition, as well as the total phenolic compounds and antioxidant activity of pulp and seed of Patauá. As for mineral composition, the high concentrations of sodium for the seed (84.21 mg 100 g-1) and pulp (71.21 mg 100 g-1), as well as magnesium values of 48.31 mg 100 g-1 for the seed and 41.23 mg 100 g-1 for the pulp. Among the micronutrients, the high concentration of iron in the pulp is 1.84 mg 100 g-1 for the pulps, and the manganese was 1.10 mg 100 g-1 for the seeds. The total phenolic compounds found in the seeds were relatively higher than for the pulps with values of 356.12 ± 0.12 mg GAEq g-1 and 321.03 ± 0.43 mg GAEq g-1, as well as the more significant antioxidant activity for the seeds than for the pulp. Carotenoids concentration in the seeds found of 2.52 ± 0.04 mg mL-1 and vitamin C concentrations were also quantified in trace concentrations, presenting the fruits of Patauá high biotechnological interest in the food and cosmetic industry.

Apatite flotation using pataua palm tree oil as collector

Most apatite concentrates, essential for the fertilizer industry, are produced using froth flotation, where collectors play a pivotal role. Although vegetable oil-derived surfactants have been used for decades in flotation processes, raw materials which do not compete with human or animal nutrition deserve special attention. This study investigated the pataua palm tree (Oenocarpus bataua) oil regarding to its fatty acids chemical profile, saponification and iodine values, acidity index, and evaluated its potential as a source for a collector to be employed in phosphate ore flotation. The results indicated that the pataua oil is primarily composed of oleic acid, with minor contents of linoleic, palmitic, lauric, myristic, palmitoleic, stearic and linolenic acids. Selectivity of apatite from quartz and calcite was achieved at neutral and alkaline pH with dosages as low as 0.3 mg.g−1.These findings were interpreted based on FTIR and zeta potential measurements, indicating that the collector adsorption onto the apatite surface occurred through mechanisms of chemisorption and calcium salts precipitation. This study suggested pataua oil as a prospective collector in flotation systems aiming at apatite concentration with an environmentally sustainable strategy.

Impact of the Mode of Extraction on the Lipidomic Profile of Oils Obtained from Selected Amazonian Fruits.

Oils and fats are important raw materials in food products, animal feed, cosmetics, and pharmaceuticals among others. The market today is dominated by oils derive, d from African palm, soybean, oilseed and animal fats. Colombia’s Amazon region has endemic palms such as Euterpe precatoria (açai), Oenocarpus bataua (patawa), and Mauritia flexuosa (buriti) which grow in abundance and produce a large amount of ethereal extract. However, as these oils have never been used for any economic purpose, little is known about their chemical composition or their potential as natural ingredients for the cosmetics or food industries. In order to fill this gap, we decided to characterize the lipids present in the fruits of these palms. We began by extracting the oils using mechanical and solvent-based approaches. The oils were evaluated by quantifying the quality indices and their lipidomic profiles. The main components of these profiles were triglycerides, followed by diglycerides, fatty acids, acylcarnitine, ceramides, ergosterol, lysophosphatidylcholine, phosphatidyl ethanolamine, and sphingolipids. The results suggest that solvent extraction helped increase the diglyceride concentration in the three analyzed fruits. Unsaturated lipids were predominant in all three fruits and triolein was the most abundant compound. Characterization of the oils provides important insights into the way they might behave as potential ingredients of a range of products. The sustainable use of these oils may have considerable economic potential.

Finding forest management in prehistoric Amazonia

Abstract This paper addresses a topic highlighted in recent arguments by Amazonian scholars: the extent to which forms of forest management in prehistory influenced the past and present composition of terra firme and riverine forests. New information on palm phytolith characteristics enabled phytolith analysis on soils sampled from underneath forests in western and central Amazon. We evaluated whether three major economic palms, Oenocarpus bataua, O. bacaba, and Euterpe precatoria, thought to have been significantly enriched by human activities, demonstrated such enrichment. All three palms are hyperdominant species today. We also examined expanded modern phytolith reference collections in a possible context of human management of other arboreal species that involved changes in overall forest structure and diversity during the past several thousand years. Results indicate little to no enrichment of the palms and largely stable forest structure and diversity in terra firme forests through time. Although much research remains, results of this study indicate that prehistoric human modification of Amazonian forest and creation of species hyperdominance was less influential than currently proposed by some Amazonian scholars. Findings contribute toward resolving questions concerning the temporal and spatial scale and characteristics of pre-Columbian human impacts across Amazonia. They also suggest cross-disciplinary insights surrounding the proposed new geological epoch of the Anthropocene.

Expressões fenológicas de palmeiras em coleções botânicas associadas às condições pluviais na Floresta Tapajós

A família Arecaceae esta incluída nas hiperdominâncias no bioma Amazônia, tendo muitas espécies de interesse às populações locais. Objetivou-se avaliar registros fenológicos herborizados de palmeiras associados à precipitação pluvial na Flona Tapajós e seu entorno. Dados nos herbários da Embrapa Amazônia Oriental (IAN/EMBRAPA) e do Museu Paraense Emílio Goeldi (MPEG) foram contabilizados avaliando informações fenológicas de Arecaceae. Também, foram avaliados dados pluviais disponíveis de Belterra, Santarém e Rurópolis. Foram contabilizados os dados pluviais e avaliados com base nas datas de floração e/ou frutificação, descrita nos registros dos herbários. Também, avaliou-se o total pluvial nos dois meses anteriores, como indicativo do volume hídrico, nas áreas de ocorrência das palmeiras. Foram encontradas 34 espécies com predominância dos gêneros Bactris, Geonoma e Oenocarpus, sendo que o Oenocarpus bataua Mart. (patauá) apresentou a maior frequência, nos registros. A floração e/ou frutificação predominou no mês de novembro. No trimestre menos pluvioso (agosto a outubro) as chuvas foram inferiores a 50 mm, indicando que essa expressão fenológica no mês que inicia o período de chuvas esparsas na região apresenta-se como estratégia de perpetuação das espécies analisadas e conclui-se que em materiais botânicos herborizados é possível avaliar respostas à condições climáticas na Amazônia.

Genetic structuring in a Neotropical palm analyzed through an Andean orogenesis-scenario.

Andean orogenesis has driven the development of very high plant diversity in the Neotropics through its impact on landscape evolution and climate. The analysis of the intraspecific patterns of genetic structure in plants would permit inferring the effects of Andean uplift on the evolution and diversification of Neotropical flora. In this study, using microsatellite markers and Bayesian clustering analyses, we report the presence of four genetic clusters for the palm Oenocarpus bataua var. bataua which are located within four biogeographic regions in northwestern South America: (a) Chocó rain forest, (b) Amotape‐Huancabamba Zone, (c) northwestern Amazonian rain forest, and (d) southwestern Amazonian rain forest. We hypothesize that these clusters developed following three genetic diversification events mainly promoted by Andean orogenic events. Additionally, the distinct current climate dynamics among northwestern and southwestern Amazonia may maintain the genetic diversification detected in the western Amazon basin. Genetic exchange was identified between the clusters, including across the Andes region, discarding the possibility of any cluster to diversify as a distinct intraspecific variety. We identified a hot spot of genetic diversity in the northern Peruvian Amazon around the locality of Iquitos. We also detected a decrease in diversity with distance from this area in westward and southward direction within the Amazon basin and the eastern Andean foothills. Additionally, we confirmed the existence and divergence of O. bataua var. bataua from var. oligocarpus in northern South America, possibly expanding the distributional range of the latter variety beyond eastern Venezuela, to the central and eastern Andean cordilleras of Colombia. Based on our results, we suggest that Andean orogenesis is the main driver of genetic structuring and diversification in O. bataua within northwestern South America.

The relative contributions of seed and pollen dispersal to gene flow and genetic diversity in seedlings of a tropical palm.

Seed and pollen dispersal shape patterns of gene flow and genetic diversity in plants. Pollen is generally thought to travel longer distances than seeds, but seeds determine the ultimate location of gametes. Resolving how interactions between these two dispersal processes shape microevolutionary processes is a long-standing research priority. We unambiguously isolated the separate and combined contributions of these two dispersal processes in seedlings of the animal-dispersed palm Oenocarpus bataua to address two questions. First, what is the spatial extent of pollen versus seed movement in a system characterized by long-distance seed dispersal? Second, how does seed dispersal mediate seedling genetic diversity? Despite evidence of frequent long-distance seed dispersal, we found that pollen moves much further than seeds. Nonetheless, seed dispersal ultimately mediates genetic diversity and fine-scale spatial genetic structure. Compared to undispersed seedlings, seedlings dispersed by vertebrates were characterized by higher female gametic and diploid seedling diversity and weaker fine-scale spatial genetic structure for female gametes, male gametes and diploid seedlings. Interestingly, the diversity of maternal seed sources at seed deposition sites (Nem ) was associated with higher effective number of pollen sources (Nep ), higher effective number of parents (Ne ) and weaker spatial genetic structure, whereas seed dispersal distance had little impact on these or other parameters we measured. These findings highlight the importance maternal seed source diversity (Nem ) at frugivore seed deposition sites in driving emergent patterns of fine-scale genetic diversity and structure.

Habitat loss and fragmentation reduce effective gene flow by disrupting seed dispersal in a neotropical palm

Habitat loss and fragmentation often reduce gene flow and genetic diversity in plants by disrupting the movement of pollen and seed. However, direct comparisons of the contributions of pollen vs. seed dispersal to genetic variation in fragmented landscapes are lacking. To address this knowledge gap, we partitioned the genetic diversity contributed by male gametes from pollen sources and female gametes from seed sources within established seedlings of the palm Oenocarpus bataua in forest fragments and continuous forest in northwest Ecuador. This approach allowed us to quantify the separate contributions of each of these two dispersal processes to genetic variation. Compared to continuous forest, fragments had stronger spatial genetic structure, especially among female gametes, and reduced effective population sizes. We found that within and among fragments, allelic diversity was lower and genetic structure higher for female gametes than for male gametes. Moreover, female gametic allelic diversity in fragments decreased with decreasing surrounding forest cover, while male gametic allelic diversity did not. These results indicate that limited seed dispersal within and among fragments restricts genetic diversity and strengthens genetic structure in this system. Although pollen movement may also be impacted by habitat loss and fragmentation, it nonetheless serves to promote gene flow and diversity within and among fragments. Pollen and seed dispersal play distinctive roles in determining patterns of genetic variation in fragmented landscapes, and maintaining the integrity of both dispersal processes will be critical to managing and conserving genetic variation in the face of continuing habitat loss and fragmentation in tropical landscapes.

Rare genotype advantage promotes survival and genetic diversity of a tropical palm.

Negative density dependence, where survival decreases as density increases, is a well-established driver of species diversity at the community level, but the degree to which a similar process might act on the density or frequency of genotypes within a single plant species to maintain genetic diversity has not been well studied in natural systems. In this study, we determined the maternal genotype of naturally dispersed seeds of the palm Oenocarpus bataua within a tropical forest in northwest Ecuador, tracked the recruitment of each seed, and assessed the role of individual-level genotypic rarity on survival. We demonstrate that negative frequency-dependent selection within this species conferred a survival advantage to rare maternal genotypes and promoted population-level genetic diversity. The strength of the observed rare genotype survival advantage was comparable to the effect of conspecific density regardless of genotype. These findings corroborate an earlier, experimental study and implicate negative frequency-dependent selection of genotypes as an important, but currently underappreciated, determinant of plant recruitment and within-species genetic diversity. Incorporating intraspecific genetic variation into studies and theory of forest dynamics may improve our ability to understand and manage forests, and the processes that maintain their diversity.

A new hypothesis for the importance of seed dispersal in time

Most studies on seed dispersal in time have focused on seed dormancy and the physiological triggers for germination. However, seed dispersed by animals with low metabolic and moving rates, and long gut-passage times such as terrestrial turtles, could be considered another type of dispersal in time. This study tests the hypothesis that seeds dispersed in time may lower predation rates. We predicted that seeds deposited below parent trees after fruiting fall has finished is advantageous to minimize seed predators and should show higher survival rates. Four Amazonian plant species, Dicranostyles ampla, Oenocarpus bataua, Guatteria atabapensis and Ocotea floribunda, were tested for seed survival probabilities in two periods: during fruiting and 10-21 days after fruiting. Experiments were carried out in two biological stations located in the Colombian Amazon (Caparú and Zafire Biological Stations). Seed predation was high and mainly caused by non-vertebrates. Out of the four plant species tested, only Guatteria atabapensis supported the time escape hypothesis. For this species, seed predation by vertebrates after the fruiting period increased (from 4.1% to 9.2%) while seed predation by non-vertebrates decreased (from 54.0% to 40.2%). In contrast, seed predation by vertebrates and by non-vertebrates after the fruiting period in D. ampla increased (from 7.9% to 22.8% and from 40.4% to 50.6%, respectively), suggesting predator satiation. Results suggest that for some species dispersal in time could be advantageous to avoid some type of seed predators. Escape in time could be an additional dimension in which seeds may reach adequate sites for recruitment. Thus, future studies should be address to better understand the survival advantages given by an endozoochory time-dispersal process.

FATTY ACIDS CONTENT IN UNGURAHUA OIL (OENOCARPUS BATAUA) FROM ECUADOR. FINDINGS ON ADULTERATION OF UNGURAHUA OIL IN ECUADOR

Objective: The aim of this study was to determine the fatty acids composition in an ungurahua seeds oil (Oenocarpus bataua) sample cultivated in Ecuador and to determine eventual adulteration in the composition of commercial ungurahua oil.Methods: Oil was obtained from ungurahua seeds using the cold pressing method. Fatty acids analysis was performed using the gas chromatography (GC) method with a mass selective detector and using the database library NIST14.L to identify the compounds.Results: Methyl esters fatty acids were identified from ungurahua (O. bataua) using the GC mass spectrometer analytical method. Ungurahua oil presented a high content of monounsaturated fatty acids with 82.03% of oleic acids. A fraud in the composition of fatty acids present in commercial ungurahua oil was found as fatty acids had a value of only 36.77% of oleic acids. The content of linoleic acid can be used to determine adulteration of this oil.Conclusions: Ungurahua seeds are a good source of monounsaturated and fatty acids. The content of oleic acid is higher than in olive oil. Ungurahua can help reducing cardiovascular diseases risk in Ecuador due to its good composition of monounsaturated fatty acids. Ungurahua oil is a good option to be used in the food industry for different uses.

Palmas útiles en tres comunidades indígenas de La Pedrera, Amazonia colombiana

Se estudió el conocimiento y el uso de las palmas por parte de las comunidades indígenas Angostura, Curare y Yukuna, cercanas a la cabecera del corregimiento de La Pedrera, Amazonia colombiana. Entre junio y julio de 2010 se registró información etnobotánica mediante entrevistas estructuradas realizadas a 53 personas informantes de dichas comunidades. Los datos se analizaron aplicando los índices de importancia relativa de categoría de uso (IR(c)), importancia cultural relativa (IC(s)) e importancia relativa de cada especie (IR(s)). Se encontraron 34 especies de palmas útiles y nueve categorías de uso. Según el IR(c) las categorías de uso más importantes fueron Alimentación humana, Construcción y Utensilios y herramientas. Dentro de estas se destaca el consumo directo de los frutos, la elaboración de bebidas, la utilización de la palma entera o de las hojas para la construcción de viviendas y la elaboración de instrumentos de caza y utensilios para el uso cotidiano. Según el IR(s) e IC(s) las especies más importantes fueron el chontaduro (Bactris gasipaes), el canangucho (Mauritia flexuosa), el milpesos (Oenocarpus bataua) y el asaí (Euterpe precatoria). Se confirma que las palmas juegan un papel importante en las tres comunidades y se evidencia una disminución del conocimiento en los usos asociados a la cultura y a las ceremonias rituales. Por otra parte, según los índices de importancia relativa y cultural coinciden las mismas especies de palmas registradas en otras comunidades amazónicas colombianas.

Genetic diversity of dispersed seeds is highly variable among leks of the long-wattled umbrellabird

Frugivorous animals frequently generate clumped distributions of seeds away from source trees, but genetic consequences of this phenomenon remain poorly resolved. Seed dispersal of the palm Oenocarpus bataua by long-wattled umbrellabirds Cephalopterus penduliger generates high seed densities in leks (i.e., multi-male display sites), providing a suitable venue to investigate how dispersal by this frugivore may influence seed source diversity and genetic structure at local and landscape levels. We found moderate levels of maternal seed source diversity in primary seed rain across five leks in northwest Ecuador (unweighted mean alpha diversity α = 9.52, weighted mean αr = 3.52), with considerable variation among leks (αr range: 1.81–24.55). Qualitatively similar findings were obtained for allelic diversity and heterozygosity. Higher densities of O. bataua adults around leks were associated with higher values of αr and heterozygosity (non-significant trends) and allelic diversity (significant correlation). Seed source overlap between different leks was not common but did occur at low frequency, providing evidence for long-distance seed dispersal by umbrellabirds into leks. Our findings are consistent with the idea that seed pool diversity within leks may be shaped by the interaction between density of local trees, which can vary considerably between leks, and umbrellabird foraging ecology, particularly a lack of territorial defense of fruiting trees. Taken as a whole, this work adds to our growing appreciation of the ways resource distribution and associated frugivore foraging behaviors mechanistically shape seed dispersal outcomes and the distribution of plant genotypes across the landscape.

Revisiting Amazonian Plants for Skin Care and Disease

This review concerns five species of trees and palm trees that occur as dominant plants in different rainforest areas of the Amazon region. Due to their abundance, these species can be exploited as sustainable sources of botanical materials and include Carapa guianensis Aubl., family Meliaceae; Eperua falcata Aubl., family Fabaceae; Quassia amara L., family Simaroubaceae; and Attalea speciosa Mart. and Oenocarpus bataua Mart., family Arecaceae. For each species, the general features, major constituents, overall medicinal properties, detailed dermatological and skin care applications, and possible harmful effects have been considered. The major products include seed oils from A. speciosa and C. guianensis, fruit oil from O. bataua, and active compounds such as limonoids from C. guianensis, flavonoids from E. falcata, and quassinoids from Q. amara. The dermatologic and cosmetic applications of these plants are growing rapidly but are still widely based on empiric knowledge. Applications include skin rehydration and soothing; anti-inflammatory, antiage, and antiparasite effects; hair care; burn and wound healing; and the amelioration of rosacea and psoriasis conditions. Despite a limited knowledge about their constituents and properties, these species appear as promising sources of bioactive compounds for skin care and health applications. An improvement of knowledge about their properties will provide added value to the exploitation of these forest resources.

Hosts of Raoiella indica Hirst (Acari: Tenuipalpidae) Native to the Brazilian Amazon

The expansion of red palm mite (RPM), Raoiella indica (Acari: Tenuipalpidae) in Brazil could impact negatively the native plant species, especially of the family Arecaceae. To determine which species could be at risk, we investigated the development and reproductive potential of R. indica on 19 plant species including 13 native species to the Brazilian Amazon (12 Arecaceae and one Heliconiaceae), and six exotic species, four Arecaceae, a Musaceae and a Zingiberaceae. Values of the instantaneous rate of increase (ri) were initially estimated at 7, 14, 21 and 28 days after infestation of each species. Higher values of ri (&gt; 0.05) were determined on the Arecaceae Adonidia merrillii, Astrocaryum jauari, Cocos nucifera, Bactris simplicifrons, Mauritia flexuosa, Phoenix dactylifera and Socratea exorrhiza, and on the Heliconiaceae Heliconia psittacorum Sassy; these were classified as “potential primary hosts”. Lower, but still positive values of ri (0-0.05) were determined on the Arecaceae Bactris maraja, Oenocarpus bacaba, Oenocarpus bataua and on the Musaceae Musa × paradisiaca (Prata variety); these were classified as “potential secondary hosts”. Negative values of ri were determined for the remaining plants, i.e., the Arecaceae Astrocaryum aculeatum, Attalea maripa, Bactris gasipaes, Elaeis guineensis, Euterpe oleracea, Euterpe precatoria, and the Zingiberaceae Alpinia rosea; these were considered “non-hosts”. Species with ri &lt; 0.05 were considered not to be threatened by the RPM. Biological parameters of RPM were evaluated on the plant species with positive ri (except B. maraja) and two native species with negative ri (E. oleracea and E. precatoria). Mean developmental time ranged from 14.7 days on C. nucifera to 21.4 days on Musa × paradisiaca, showing a significant influence of the plant substrate. Immature viability, oviposition rate, net reproductive rate (R0) and intrinsic rate of increase (rm) were affected by the plant species.
