"Assessing the role of dispersed floral resources for managed bees in providing supporting ecosystem services for crop pollination."

Full textAbstract:
Most pollination ecosystem services studies have focussed on wild pollinators and their dependence on natural floral resources adjacent to crop fields. However, managed pollinators depend on a mixture of floral resources that are spatially separated from the crop field. Here, we consider the supporting role these resources play as an ecosystem services provider to quantify the use and availability of floral resources, and to estimate their relative contribution to support pollination services of managed honeybees. Beekeepers supplying pollination services to the Western Cape deciduous fruit industry were interviewed to obtain information on their use of floral resources. For 120 apiary sites, we also analysed floral resources within a two km radius of each site based on geographic data. The relative availability of floral resources at sites was compared to regional availability. The relative contribution of floral resources-types to sustain managed honeybees was estimated. Beekeepers showed a strong preference for eucalypts and canola. Beekeepers selectively placed more hives at sites with eucalypt and canola and less with natural vegetation. However, at the landscape-scale, eucalypt was the least available resource, whereas natural vegetation was most common. Based on analysis of apiary sites, we estimated that 700,818 ha of natural vegetation, 73,910 ha of canola fields, and 10,485 ha of eucalypt are used to support the managed honeybee industry in the Western Cape. Whereas the Cape managed honeybee system uses a bee native to the region, alien plant species appear disproportionately important among the floral resources being exploited. We suggest that an integrated approach, including evidence from interview and landscape data, and fine-scale biological data is needed to study floral resources supporting managed honeybees.

Full textAbstract:
Knowledge of the flowering process — an important trait in ornamental plants such as roses — is necessary for efficient control of flowering. This study was carried out to develop and characterize new resources to gain further insight into floral control in rose. We studied floral initiation in a nonrecurrent blooming rose (hybrid of Rosa wichurana ) and a recurrent blooming rose ( Rosa hybrida Black Baccara®). In Black Baccara®, floral initiation took place rapidly after bud burst, whereas in the greenhouse R. wichurana remained vegetative. During floral initiation, the apex enlarged and domed quickly and concomitantly. This is the first description of this transition between the vegetative and floral bud stages in rose. From these vegetative and pre-floral tissues, two cDNA libraries were constructed and 5000 ESTs sequenced. By collecting our ESTs and those available in public databases, we developed a comprehensive database representing ~5000 unique sequences after clustering. By screening this database for candidate genes involved in the flowering process, we identified 13 genes potentially involved in gibberellic acid signalling, photoperiod pathways, and floral development. Based on expression data, we put forward different hypotheses on the control of flowering in rose (photoperiod control and involvement of gibberellins) relative to what is already known in Arabidopsis .

Full textAbstract:
Mass-flowering crops, such as oilseed rape (OSR; Brassica napus), provide pulses of nectar and pollen, helping to support pollinators and their pollination services in agricultural landscapes. Despite their value to declining pollinators, varietal in-field OSR testing focusses on agronomic traits, with floral resources being largely overlooked. OSR has a high varietal turnover, and consequently, floral resource data collected for a specific variety quickly become redundant. Here, we explore the potential to predict floral resource availability using agronomic trait data routinely collected in varietal trials. To build predictive models, we investigated the relationships between agronomic traits and pollen and nectar availability in 19 OSR varieties. Nectar quality was positively influenced by early vigour, as well as winter hardiness in conventional varieties and stem stiffness in hybrid varieties. Pollen quantity was driven by different traits, with early maturation having a negative impact in conventional varieties and resistance to lodging having a positive impact in hybrid varieties. Our study highlights the potential to predict floral resources using agronomic trait data, enabling the rapid assessment of these key resources in future OSR varieties without costly sampling. Agronomic traits relating to increased nectar quality were also agronomically favourable, indicating benefits to both pollinators and growers. The inclusion of modelled floral resource data in recommended varietal lists would enable growers to make informed decisions about varietal selection based on local pollinator populations.

Full textAbstract:
To describe plant phenological patterns and correlate functioning for the quantity and quality of resources available for the pollinator, it is crucial to understand the temporal dynamics of biological communities. In this way, the pollination syndromes of 46 species with different growth habits (trees, shrubs, herbs, and vines) were examined in an area of Caatinga vegetation, northeastern Brazil (7° 28′ 45″ S and 36° 54′ 18″ W), during two years. Flowering was monitored monthly in all the species, over two years (from January 2003 to December 2004). Pollination syndromes were characterised based on floral traits such as size, colour, morphology, symmetry, floral resources, as well as on direct visual observation of floral visitors on focal plants and published information. We observed differences among the plant growth habits with respect to floral traits, types of resources offered, and floral syndromes. The flowering periods of the species varied among floral syndrome groups. The majority of the melittophilous species flowered during the rainy season in the two study years, while the species of the other pollination syndroms flowered at the end of the dry season. An asynchrony of flowering was noted among the chiropterophilous species, while the phalenophilous group concentrated during the rainy season. The overall availability of floral resources was different during the rainy and the dry seasons, and also it varied among plants with different growth habits. The availability of oil-flowers coincided with the period of low nectar availability. We observed a relationship between the temporal distribution of the pollination syndromes and the availability of floral resources among each growth habits in this tropical ecosystem. Resource allocation in seasonal environments, such as the Caatinga, can function as a strategy for maintaining pollinators, facilitating therefore the reproductive success of plant species. The availability of floral resources during all the year, specially in seasonal environments such as the Caatinga, may function as a strategy to maintain pollinator populations ensuring the reproductive success of the plants.

Full textAbstract:
Information on floral resource costs is fundamental for understanding how selection operates on floral morphology. In this study, I explored the cost of maturing flowers in a self-incompatible population of the ligulate composite Crepis tectorum L. by experimentally manipulating floral investment and then monitoring the response in reproductive effort. Plants on which the heads were removed during the initial stage of ligule expansion had a higher reproductive effort than plants whose heads were removed immediately after flower maturation, and the latter plants had a higher reproductive effort than plants on which all flowers were permitted to set fruit. Judging from biomass estimates and the magnitude of the observed tradeoffs, the amount of resources allocated to maturing flowers was about half as great as the amount of resources devoted to fruit maturation. These and other results suggest that floral tradeoffs may exert negative selection on floral size variables.

Full textAbstract:
Hummingbird communities tend to respond to variation in resources, having a positive relationship between abundance and diversity of food resources and the abundance and/or diversity of hummingbirds. Here we examined the influence of floral resource availability, as well as seasonality and type of habitat on the composition of hummingbird species. The study was carried out in two habitats of eastern Brazilian mountaintops. A gradient representative of the structure of hummingbird community, based on species composition, was obtained by the ordination of samples using the method of non-metric multidimensional scaling. The composition of hummingbird species was influenced by the type of habitat and floral resource availability, but not by seasonality. Hummingbird communities differ between habitats mainly due to the relative abundance of hummingbird species. The variation in composition of hummingbird species with the variation in floral resource availability may be related to differences in feeding habits of hummingbirds. Hummingbird species with the longest bills visited higher proportions of ornithophilous species, while hummingbirds with shorter bills visited higher proportions of non-ornithophilous species. The results demonstrate that at local-scale the composition of hummingbird species is affected by the type of habitat and floral resources availability, but not by seasonality.

Butterflies fulfill a unique role among insect pollinators as long-distance flyers. This makes butterflies particularly valuable as vectors of genetic diversity among spatially isolated plant populations. Like many insects, though, butterfly populations have experienced significant declines in recent years. To help inform conservation efforts, and to investigate community and species level dynamics, I studied butterflies and their floral resources as part of a three year pollinator survey across the state of North Dakota. At the community level, I analyzed butterfly-flower interaction networks across space and time. I then examined the specialization of individual species within those networks and their contributions to network structure. I also evaluated spatial and temporal distribution patterns of monarch butterflies, regal fritillaries, and their plant resources. Results revealed dynamic spatiotemporal relationships between butterflies and their plant resources that have important implications for conservation efforts and the study of ecological communities.

Full textAbstract:
Relying on wild bees for pollination services has become necessary as the global demand for crops dependent on animal pollination increases. If wild bee populations are to establish and persist in agricultural landscapes, there must be sufficient floral resources over time and space. This study examines the relationship between bee visits in agroecosystems and the spatiotemporal availability of floral resources over one season. I expected that landscapes with greater floral resources earlier in the season would subsequently experience more bee visits than landscapes with fewer early-season floral resources, and that the spatiotemporal scale of this effect would differ among taxa. I measured bee visitation rate and floral resource density over three spatial scales and during four time-periods spanning one season, in 27 agricultural sites across Ontario and Québec, Canada. The present abundance of floral resources at a local scale positively influenced bee visits across all sampling periods. However, differences in the temporal scale of bees’ response to floral resources were observed at landscape scales. Past and present floral resources were positively or negatively associated with bee visits depending on the time of season and which taxon was examined. The number of visits by Andrenidae, honey bees, and bumble bees increased with floral resource abundance in previous time-periods, while other taxa exhibited a negative association with past floral resources, suggesting possible dilution of bee populations at a landscape scale. Understanding the scales at which bee taxa are influenced by floral resources can allow development of land management strategies that could enhance crop pollination and conserve species threatened by agricultural intensification.

Studies on hummingbird/plant interactions in the Atlantic Forest have been providing major data on ornithophilous plants and on the role of these birds as pollen vectors and maintainers of plant communities. The aim of this study was to investigate a plant community used by hummingbirds, in order to recognize flowering phenological patterns and to identify pollen loads transported by visiting trochilidae. Fieldwork was performed from April 2009 to August 2011 in the understory of an Atlantic Forest area within Michelin Ecological Reserve, in Igrapi?na municipality, Bahia State. We identified hummingbirds from focal observations in flowering plants, recording their foraging strategies and the local of pollen deposition in their bodies. Data on morphology and floral biology were recorded for plants visited by hummingbirds, such as the number of flowers and buds monthly produced and if the plant was ornithophilous or not. Pollen attached to the beak, head, throat and chest of captured hummingbirds was removed, identified and counted in laboratory. About 18 plant species, most of them ornithophilous (83%), were visited by 13 hummingbird species, with Phaethornis ruber being the most frequent pollen vector. The plant community showed a continuous flowering, with sequential flowering peaks during the studied period. Sixteen pollen types and eight hummingbird species were recorded, with the beak being the main area for pollen deposition (58%), followed by the head (30%), throat (11%) and chest (1%). Differences on the local of pollen deposition on birds reduce the chance of mixing pollen from different species, allowing their coexistence by the sharing of the same pollen vector. Continuous flowering within the plant community assure the presence of their pollinators in the area, avoiding population dislocation towards floral resources. A high investment on floral morphology specialization allows a great deposition of pollen grains over a safe place on the body of the hummingbirds, maximizing plant reproductive success.

Dos beija-flores capturados, foi removido o p?len impregnado em seu bico, cabe?a, garganta e peito. Os tipos pol?nicos foram identificados e contabilizados em laborat?rio. Foram registradas dezoito esp?cies de plantas, a maioria ornit?fila (83%), sendo visitadas por beija-flores. Treze esp?cies de beija-flores visitaram as plantas, sendo Phaethornis ruber o vetor de p?len mais frequente. Durante o per?odo de estudo, a comunidade vegetal apresentou flora??o cont?nua com picos de flora??o sequenciais. Dezesseis tipos pol?nicos foram identificados em oito esp?cies de beija-flores capturadas, sendo o bico o principal local de deposi??o de p?len (58%), seguido da cabe?a (30%), garganta (11%) e peito (1%). Diverg?ncias no local de deposi??o de p?len no corpo das aves reduz a probabilidade de mistura de p?len heteroespec?fico, permitindo a coexist?ncia de plantas que se beneficiam da partilha de polinizadores. A flora??o cont?nua da comunidade garante a presen?a de seus polinizadores na ?rea, evitando deslocamentos populacionais em busca de recurso. O alto investimento na morfologia floral especializada proporciona a deposi??o de grande quantidade de gr?os de p?len em local seguro do corpo da ave, maximizando o sucesso reprodutivo vegetal.

Full textAbstract:
Livestock management influences the extent to which grazing lands provide resources for native species. We compared how livestock species ? sheep or cattle ? affected floral resources and bee and butterfly communities in low-diversity, post-Conservation Reserve Program (CRP) pastures managed with patch-burning. We sampled bees and butterflies three times per season 2017-2019 and counted flowering stems within 1 m of transects. Pastures grazed by sheep had significantly fewer flowers and significantly lower floral richness than cattle pastures. Native bees were three to sixteen times more abundant in cattle pastures compared to sheep. Butterfly communities were similar between grazing treatments, because agricultural-tolerant, habitat generalists comprised the majority of the butterfly community. Grassland-obligate butterflies comprised only 2% of observations. The dearth of grassland-obligate butterfly species and low native bee abundances suggest that post-CRP fields, especially those grazed by sheep, do not provide abundant and diverse floral resources for native bees and imperiled butterfly species.

Os estudos de biologia reprodutiva são fundamentais para a conservação e manejo das espécies de plantas, uma vez que o período reprodutivo é uma fase de grande importância para a dinâmica das populações e sobrevivência das espécies . Esta dissertação teve como objetivo contribuir para o conhecimento da morfologia floral, biologia floral e reprodutiva de Butia odorata (Barb. Rodr.) Noblick, além de identificar os agentes polinizadores e suas relações com as flores. O trabalho foi realizado em dois países, no Uruguai (em La Paloma, Departamento de Rocha) e no Brasil (em Porto Alegre, Rio Grande do Sul). Foram identificadas as fases de floração, antese masculina e feminina. Foi estimado o número de flores masculinas e femininas por ráquila na inflorescência, e a relação existente entre flores masculinas e femininas. Foi verificada a coloração das ráquilas e das flores. As flores foram caracterizadas quanto à sua morfologia e morfometria. Foram identificadas as ordens de insetos que visitaram as inflorescências, a relação dos insetos com as flores, os recursos florais coleta dos e o período de visitação durante as fases de floração. As flores de Butia odorata são unissexuais, hipóginas, actinomorfas, diclamídeas e sésseis. As flores masculinas e femininas ocorrem na mesma inflorescência e possuem formatos distintos, sendo as primeiras muito mais numerosas do que as segundas. As flores masculinas estão dispostas por toda a ráquila, com maior concentração do meio para o ápice, as flores femininas são encontradas do meio para a base da ráquila, formando tríades com duas masculinas. Existe variabilidade genética para cor e tamanho de ráquilas e para cor das flores em inflorescências de B. odorata. A espécie apresenta mecanismos de protandria. Uma grande diversidade de espécies de insetos das ordens Hymenoptera, Coleoptera e Diptera visitam as inflorescências. Durante a antese masculina, as ordens Hymenoptera e Coleoptera são mais frequentes, enquanto que durante a antese feminina a ordem Hymenoptera se destaca. Os insetos são atraídos pelos recursos como pólen e néctar disponibilizados pelas flores. A compreensão sobre a biologia reprodutiva, apresentado nos dois capítulos da dissertação, serve de alicerce para a preservação do butiá, pois este conhecimento é de grande importância para traçar estratégias de conservação e uso de recursos genéticos e programas de melhoramento.
Studies of reproductive biology are essential for the conservation and management of plant species, once the reproductive period is a time of great importance for the population dynamics and species survival. This dissertation had as objective to contribute to uderstanding floral morphology, floral and reproductive biology of Butia odorata (Barb. Rodr.) Noblick. Also, to identify the pollinators and their relationship with the flowers. The study was conducted in two Countries, Uruguay (La Paloma, Rocha Department) and Brazil (Porto Alegre, Rio Grande do Sul State). Stages of flowering, and male and female anthesis were identified. The number of male and female flowers per rachille in the inflorescence, and the ratio between male and female flowers were estimated. The coloring of rachilles and flowers was verified. The morphology and morphometry of flowers were characterized. Orders of insects that visited the inflorescences, the relationship of insects with flowers, the collected floral resources and the period of visitation during the stages of flowering were identified. Flowers of Butia odorata are unisexual, hypogynous, actinomorphic, dichlamydeous and sessile. The male and female flowers occur on the same inflorescence and have different formats, being the male more numerous than the female. The male flowers are arranged throughout the rachille, with higher concentration from the middle to the apex. The female flowers are found from the middle to the base of rachille, forming triads with two male flowers. There is genetic variability for color and size of rachilles and for color of flowers on inflorescences of B. odorata. The species has mechanisms of protandry. A great diversity of insects' species, belonging to the Hymenoptera, Coleoptera and Diptera orders visit the inflorescences. During male anthesis, the Hymenoptera and Coleoptera orders are more frequent, whereas during female anthesis the Hymenoptera order stands. The insects are attracted by the resources such as pollen and nectar provided by the flowers. The understanding of the reproductive biology, presented in two chapters of this dissertation, serves as the foundation for the preservation of butiá, because this knowledge is of great importance to devise strategies for the conservation and use of genetic resources and breeding programs.

Although the provision of many ecosystem services has proven affected by changes in land cover and land use, the relationship between landscape structure and the production and quality of stingless bee honey has not been studied yet. This work aimed to analyze the influence of landscape structure on the production and quality of honey from the bee Jandaira (Melipona subnitida) in Rio Grande do Norte. To do so, 15 meliponaries were selected in several areas this state, in urban and rural areas and represented by different landscape structures. Land cover was mapped in scales of 300, 1000, 2000 and 3000 meters around each meliponary. Land use was classified based on 6 classes: primary forest, secondary forest, tree crop, diverse land use, water body and urbanized area. Different landscape metrics were then calculated based on these maps, using the programs ArcGIS 10.3 and Fragstats. In each meliponary were randomly selected three colonies of M. subnitida from which a sample of honey was collected. The honey collected was sent to the laboratory for physico-chemical diagnosis (humidity, pH, water activity, reducing sugars, apparent sucrose and acidity) and assessing the sensory properties (color). The condition of the colonies was assessed by measuring the relative volume of brood cells, and honey-pots. Interviews were also performed to the beekeepers to estimate the production of honey and the number of colonies. Honey production and quality and colony condition were then related to the different landscape metrics, using a model selection approach. The results show that the proximity and amount of areas of primary forest have a positive effect on honey quality. Secondary forests had a positive effect on the pH and color of honey and a negative influence over the unused space of the boxes used to rear M. subnitida. The amount of urbanized area around the meliponaries was related negatively with honey humidity and positively with the unused space of the boxes. Hence, our work shows that protect areas of preserved Caatinga and secondary forests are important to build a refuge for pollinators and ensure the current and future provision of ecosystem services
Embora a provisão de diversos serviços ecossistêmicos tenha-se mostrado afetada por mudanças no uso e cobertura da terra, a relação entre a estrutura da paisagem e a produção e qualidade de mel de abelhas sem ferrão ainda não foi estudada. Neste trabalho analisamos a influência da estrutura da paisagem sobre a produção e a qualidade de mel da abelha jandaíra (Melipona subnitida) na Caatinga do Rio Grande do Norte. Para isso, 15 meliponários foram selecionados em diversas áreas do Estado, situados em zonas urbanas e rurais e representados por diferentes estruturas da paisagem. Fizemos mapeamentos do uso e cobertura do solo em escalas de 300, 1000, 2000 e 3000 metros ao redor de cada meliponário. As paisagens foram classificadas com base em 6 variáveis: mata primária, mata secundária, cultura arbórea, uso diverso do solo, corpo d água e área urbanizada. De acordo com esses mapeamentos, calculamos diferentes métricas da paisagem, utilizando os programas ArcGIS 10.3 e Fragstats. Em cada meliponário foram escolhidas aleatoriamente três colônias de M. subnitida. De cada colônia foi retirada uma amostra de mel. O mel coletado foi encaminhado ao laboratório da UFERSA para diagnóstico físico-químico (umidade, pH, atividade de água, açúcares redutores, sacarose aparente e acidez) e sensorial (cor). Das colônias selecionadas também foram realizadas medições (comprimento, altura e largura) dos favos de cria, dos potes de mel e da caixa racional para avaliação da condição da colônia. Fizemos também entrevistas aos meliponicultores sobre a produção de mel e quantidade de colônias no meliponário. Os dados de produção e qualidade de mel, bem como de condição das colônias, foram então relacionados com as diferentes métricas da paisagem, utilizando um procedimento de seleção de modelos. Os resultados mostraram que a proximidade e quantidade de áreas de mata primária tiveram um efeito nos parâmetros de qualidade do mel. A classe da paisagem mata secundária teve efeito positivo no pH e na coloração do mel e negativo no espaço não utilizado das caixas racionais de criação de M. subnitida. Já a quantidade de área urbanizada ao redor dos meliponários relacionou-se de maneira negativa com a umidade do mel e positiva com o espaço não utilizado das caixas racionais. Portanto, proteger as áreas de caatinga preservada e as matas secundárias é a base para alicerçamos o refúgio para os polinizadores e garantir os seus serviços ecossistêmicos para o presente e futuro

Este trabalho objetivou inventariar, atravÃs de metodologia sistematizada, parte da melissofauna do maciÃo de Baturità (4 a 4 30â S e 38 45â a 39 15â W), no CearÃ, bem como, caracteriza-la ecologicamente e conhecer suas potencialidades zootÃcnicas. Selecionaram-se quatro Ãreas de bordas de fragmentos florestais (F1, F2, F3 e F4) em altitudes e vertentes diferentes onde, no perÃodo de marÃo de 2008 a agosto de 2009, mensalmente coletaram-se as abelhas com o uso de redes entomolÃgicas. Paralelamente foi realizada a coleta do material botÃnico registrado como de uso pelas abelhas. O material faunÃstico foi analisado atravÃs dos seguintes parÃmetros ecolÃgicos: curva de acumulaÃÃo das espÃcies; Ãndices de heterogeneidade; e coeficiente de similaridade. Procedeu-se à avaliÃÃo da influÃncia dos gradientes pluviomÃtricos mensais sobre a aÃÃo de forrageamento das abelhas e a ocorrÃncia de espÃcies nas Ãreas. Quanto aos Meliponina, incluiu-se, tambÃm, a influÃncia do nÃmero de espÃcies em floraÃÃo sobre essas duas variÃveis. Para as abelhas em geral foi avaliado o padrÃo de sazonalidade apresentado pelas espÃcies por famÃlia. Ao todo amostraram-se 3053 espÃcimes de abelhas, registradas 113 espÃcies, 45 gÃneros e cinco famÃlias (Andrenidae, Apidae, Colletidae, Halictidae e Megachilidae). As curvas mensais de acumulaÃÃo indicaram insuficiÃncia amostral para o levantamento geral das abelhas, contudo, para os Meliponina os procedimentos amostrais indicaram suficiÃncia. Os nÃveis de pluviosidade mensais limitaram, em algumas bordas, a aÃÃo de forrageamento das abelhas e o registro de espÃcies, jà o nÃmero de espÃcies em floraÃÃo nÃo apresentou influÃncia significativa. O estudo da fenologia das abelhas indicou que, para Apidae, nÃo houve um padrÃo caracterizadamente sazonal, enquanto para Andrenidae e Colletidae o comportamento sazonal foi extremamente evidente e, para Halictidae e Megachilidae, os aspectos da sazonalidade nÃo foram bem definidos. A composiÃÃo florÃstica das quatro Ãreas foi de 101 espÃcies, 88 gÃneros e 36 famÃlias. Nove famÃlias, representando 60,40% das espÃcies visitadas pelos Apoidea coletados, destacaram-se pela riqueza em espÃcies: Leguminosae (20 spp.), Asteraceae (9), Bignoniaceae (5), Euphorbiaceae (5), Rubiaceae (5), Sapindaceae (5), Convolvulaceae (4), Myrtaceae (4) e Solanaceae (4). Para os Meliponina registraram-se 20 espÃcies e 12 gÃneros. Uma espÃcie (Scaptotrigona sp. 3, sp. nov.) està sendo descrita como espÃcie nova. Dentre essas espÃcies, 12 destacaram-se por apresentarem potencial zootÃcnico: Cephalotrigona capitata, Frieseomelitta doederleini, Frieseomelitta francoi, Frieseomelitta varia, Melipona aff. rufiventris, Nannotrigona sp., Partamona ailyae, Plebeia aff. flavocincta, Plebeia sp., Scaptotrigona sp. 1, Scaptotrigona sp. 2, Scaptotrigona sp. 3, sp. nov. As faunas meliponÃcolas das quatro bordas apresentaram-se heterogÃneas e 80% das espÃcies fizeram uso compartilhado dos recursos trÃficos ofertados. NÃo foi verificado influÃncia do nÃmero de espÃcies floridas sobre as atividades externas das abelhas nem sobre a ocorrÃncia de espÃcies nas bordas, contudo, os nÃveis pluviomÃtricos mensais interferiram sobre esses parÃmetros. Como recursos florÃsticos de uso pelos meliponÃneos registraram-se 82 espÃcies, 71 gÃneros e 33 famÃlias. Detectou-se um baixo nÃvel de ligaÃÃo entre as bordas estudadas, evidenciando um considerÃvel grau de heterogeneidade entre as espÃcies botÃnicas. Nas quatro Ãreas, as famÃlias mais ricas em espÃcies estÃo relacionadas Ãs Leguminosae (17 spp.), Asteraceae (8), Bignoniaceae (4), Myrtaceae (4), Solanaceae (4), Convolvulaceae (3), Euphorbiaceae (3), Flacourtiaceae (3), Melastomataceae (3), Rubiaceae (3), as quais, juntas representam 63,41% das espÃcies visitadas pelas abelhas sem ferrÃo. A espÃcie Spermacoce verticillata (Rubiaceae), presente nos quatro entornos, ofertou recursos para cerca de 60% dos Meliponina.

Previous issue date: 2010-03-02The Research consisted of three experiments in Marechal Cândido Rondon city - PR, Brazil. In the first experiment the objective was to verify the influence of Apis Mellifera L. pollination on productive and physiological traits in sunflower achenes. The treatments were constituted by the combination of eight sunflower genotypes (Multissol, M734, Catissol 01, Charrua, MG2, Aguará, Helio 360 and Embrapa 122) and two tests of pollination, i) the flowers were free to insect visitation and ii) pollinators were restricted to visiting only inflorescences protected with gauze. The parameters analyzed were total productivity of seeds (PS), number of achenes per inflorescence (NA), mass of achenes per inflorescence (MA), mass of chapters (MC), chapter diameter (CD), ether extract in the achenes (EE), germination (GE), and mass of 1000 achenes (M1000). It was verified that the sunflower plants of the hybrid M734, exposed to insect pollination, showed PS and NA equal to 91,07% and 42,03%, respectively higher (p<0,05) than the plants of this hybrid with inflorescences protected with gauze. The chapters of the Catissol 01 cultivar exposed to insect pollination showed MA, MC and CD respectively, 150,52%, 130,28% e 35,06%, higher than the chapters of this cultivar protected with gauze. Inflorescences of the Embrapa 122 cultivar, free to insect visitation, presented EE and GE respectively, 52,63% e 134,29%, higher (p<0,05), than the inflorescences of this cultivar protected with gauze. Sunflower plants pollinated by Apis Mellifera presented average percentage of M1000 of 22,32% higher (p<0,05) than the plants protected with gauze, regardless of which genotype was being studied. In general, the pollination by insects enhances the productive traits and the quality of the seeds of sunflower genotypes. The second experiment was carried out with the objective of observing the type of food that africanized honey bees collect (pollen or nectar) at different times of day during the flowering period of five sunflower genotypes. The experimental design was arranged in randomized blocks split-plots scheme, with 100 treatments, four replications and two plants per experimental unit. The treatments were constituted by the combination of five genotypes of sunflower and (Helio 360, Helio 251, Charrua, Aguará e Multissol) allocated to plots and five days of observation and four time slots arranged in subplots. It could be seen that on the second and third days of sunflowers flowering there was a higher number of visits of Apis mellifera collecting nectar. It was observed that the honey bees collect pollen and nectar all they long, with peaks of collections from 7 to 8:30AM. The average density of honey bees throughout the day was 2.27 to 2.94 bees per inflorescence, and the honey bees collecting nectar were more frequent (2.28 bees / inflorescence) than honey bees collecting pollen (0.40 bees/inflorescence) on flowering days 2,94 and 2,96, respectively, and during the most visited time in the culture (7: 00 to 8:30 AM). On the third day of flowering, the hybrid Helio 360 and Aguará showed no differences amongst each other, and also showed higher (p <0.05) number of visitations of honey bees per inflorescence as compared to the other genotypes analyzed in the present study. It can be concluded that the africanized honey bees prefer to do their work of collecting food between the second and third day of flowering, between 7:00 to 8:30AM. Moreover, the hybrids Helio 360 and Aguará are more attractive to honeybees and should be recommended for maintenance and increase of number of pollinators in cultivated areas and to expand programs of honeybees pasture in the western of Paraná state, Brazil. The third experiment was carried out to evaluate the effect of the use of insecticide imidacloprid + beta-cyfluthrin on the number of visits by Apis mellifera bees to four sunflowers during the flowering season. Five plants were marked before the period of flowering of hybrids M734, Charrua, Helio 250 e Aguará, with four repetitions. Two observers remained two minutes on each plant, counting the number of honeybees in two intervals of time (from 8:30 AM to 10:00 AM and from 3:30 PM to 5:00 PM). The counting took place before the application of insecticide and twelve hours after the use of the product. It was verified that there was a significant negative effect of insecticide on the bees visitation considering the data of all hybrids, the hybrid of the M734 and Aguará. There was no effect of insecticide on the visit considering the data of the hybrid Charrua and Helio 250. It was also verified that the insecticide imidacloprid + beta-cyfluthrin causes repellence of Apis mellifera in sunflower crop. Moreover, the insecticide imidacloprid + beta-cyfluthrin was harmless to adults of Apis mellifera during blooming period for sunflowers, when applied to the lower middle third of the plants and the period in which these honeybees were not foraging. It would be necessary to assess their possible effects on young stages for further use in programs of integrated pest management in sunflower crop
A pesquisa constou de três experimentos, no município de Marechal Cândido Rondon, Paraná. No experimento I, objetivou-se verificar a influência da polinização realizada por Apis mellifera L. sobre características produtivas e fisiológicas em aquênios de girassol. Os tratamentos foram constituídos pela combinação de oito genótipos de girassol (Multissol, M734, Catissol 01, Charrua, MG2, Aguará, Helio 360 e Embrapa 122), casualizados nas parcelas, e dois testes de polinização, um livre a ação de insetos e o outro restringindo os polinizadores com sacos de filó, que foram alocados nas subparcelas. Os parâmetros analisados foram produtividade total de grãos (PT), número de aquênios por inflorescência (NA), massa de aquênios por inflorescência (MA), massa de capítulo (MC), diâmetro de capítulo (DC), teor de extrato etéreo em aquênios (EE), germinação (GE) e massa de 1000 aquênios (M1000). Verificou-se que as plantas de girassol do híbrido M734 expostas à polinização entomófila apresentaram PT e NA de 91,07% e 42,03%, respectivamente maiores (p<0,05) do que as plantas desse híbrido com inflorescências protegidas com filó. Os capítulos de girassol da variedade Catissol 01 expostos à polinização entomófila apresentaram MA, MC e DC de 150,52%, 130,28% e 35,06%, respectivamente maiores (p<0,05) do que os capítulos dessa variedade protegidos com filó. Inflorescências de girassol da variedade Embrapa 122 que ficaram livres a ação de insetos apresentaram EE e GE de 52,63% e 134,29%, respectivamente maiores (p<0,05) do que as inflorescências dessa variedade protegidas com filó. Plantas de girassol polinizadas por insetos apresentaram porcentagem média de M1000 de 22,32% maior (p<0,05) do que as plantas restringidas aos polinizadores por filó, independentemente do híbrido estudado. De maneira geral, a polinização entomófila aumenta as características produtivas e qualidade fisiológica em aquênios de girassol. O ensaio II foi conduzido com o objetivo de observar o comportamento de coleta de alimentos (néctar e pólen) de A. mellifera em cinco genótipos de girassol, em diferentes horários do dia, durante o período de florescimento da cultura. O delineamento experimental empregado foi o de blocos casualizados completos em esquema de parcelas subdivididas no tempo, com 100 tratamentos, quatro repetições e duas plantas por unidade experimental. Os tratamentos foram constituídos pela combinação de cinco genótipos de girassol (Helio 360, Helio 251, Charrua, Aguará e Multissol), alocados nas parcelas e cinco dias de observação e quatro intervalos de tempo arranjados nas subparcelas. Verificou-se pico de visitas de A. mellifera para coleta de néctar entre o segundo e terceiro dia de florescimento na cultura do girassol. Observou-se que as abelhas realizam coletas de pólen e néctar ao longo de todo o dia, com pico de coleta no período das 7 às 8h30min. A densidade média de A. mellifera ao longo do dia foi de 2,27 a 2,94 abelhas por inflorescência, sendo as abelhas coletoras de néctar mais frequentes (2,28 abelhas/inflorescência) do que as coletoras de pólen (0,40 abelhas/inflorescência) no dia de florescimento 2,94 e 2,96, respectivamente e no horário de maior visitação na cultura (7h às 08h30min). No terceiro dia do florescimento, os híbridos Helio 360 e Aguará não diferiram entre si e apresentaram maiores (p<0,05) números de visitas de abelhas por inflorescência em relação aos demais genótipos estudados. As abelhas africanizadas preferem realizar suas coletas de néctar e pólen entre o segundo e terceiro dia do florescimento do girassol, no horário das 7 às 8h30min. Os híbridos de girassol Helio 360 e Aguará são mais atrativos à A.mellifera e devem ser recomendados para manutenção e aumento de polinizadores em áreas cultivadas, bem como para pasto apícola na região Oeste do Paraná. No terceiro experimento objetivou-se verificar o efeito da aplicação do inseticida imidacloprido + beta-ciflutrina sobre a visitação de abelhas às inflorescências de quatro híbridos de girassol, durante o florescimento da cultura. Foram marcadas cinco plantas antes do período de florescimento dos híbridos M734, Charrua, Aguará e Helio 250, com quatro repetições. Dois observadores permaneceram dois minutos em cada inflorescência, contando o número de abelhas visitantes em dois intervalos de tempo (8h30min às 10h e 15h30min ás 17h). A contagem ocorreu antes da aplicação do inseticida e 12 horas após a utilização do produto na plantação. Houve efeito significativo de inseticida sobre a visitação de abelhas considerando os dados de todos os híbridos, do híbrido M734 e Aguará, sendo menor o número de visitas de abelhas africanizadas às inflorescências após a aplicação do produto. Não houve efeito de inseticida sobre a visitação nos híbridos Charrua e Helio 250. Constatou-se que o inseticida imidacloprido + beta-ciflutrina causa repelência a A. mellifera na cultura do girassol. Além disso, o inseticida imidacloprido + beta-ciflutrina foi inofensivo aos adultos de A. mellifera, durante o florescimento do girassol, quando aplicado no terço médio inferior das plantas e no período em que essas abelhas não estavam forrageando, sendo necessária a avaliação de seus possíveis efeitos em fases jovens para posterior utilização em programas de manejo integrado de pragas na cultura do girassol

Full textAbstract:
A fundamental responsibility of the National Park Service is to ensure that park resources are preserved, protected, and managed in consideration of the resources themselves and for the benefit and enjoyment by the public. Through the inventory, monitoring, and study of park resources, we gain a greater understanding of the scope, significance, distribution, and management issues associated with these resources and their use. This baseline of natural resource information is available to inform park managers, scientists, stakeholders, and the public about the conditions of these resources and the factors or activities which may threaten or influence their stability. There are several different categories of geologic or stratigraphic units (supergroup, group, formation, member, bed) which represent a hierarchical system of classification. The mapping of stratigraphic units involves the evaluation of lithologies, bedding properties, thickness, geographic distribution, and other factors. If a new mappable geologic unit is identified, it may be described and named through a rigorously defined process that is standardized and codified by the professional geologic community (North American Commission on Stratigraphic Nomenclature 2005). In most instances when a new geologic unit such as a formation is described and named in the scientific literature, a specific and well-exposed section of the unit is designated as the type section or type locality (see Definitions). The type section is an important reference section for a named geologic unit which presents a relatively complete and representative profile for this unit. The type or reference section is important both historically and scientifically, and should be recorded such that other researchers may evaluate it in the future. Therefore, this inventory of geologic type sections in NPS areas is an important effort in documenting these locations in order that NPS staff recognize and protect these areas for future studies. The documentation of all geologic type sections throughout the 423 units of the NPS is an ambitious undertaking. The strategy for this project is to select a subset of parks to begin research for the occurrence of geologic type sections within particular parks. The focus adopted for completing the baseline inventories throughout the NPS was centered on the 32 inventory and monitoring networks (I&M) established during the late 1990s. The I&M networks are clusters of parks within a defined geographic area based on the ecoregions of North America (Fenneman 1946; Bailey 1976; Omernik 1987). These networks share similar physical resources (geology, hydrology, climate), biological resources (flora, fauna), and ecological characteristics. Specialists familiar with the resources and ecological parameters of the network, and associated parks, work with park staff to support network level activities (inventory, monitoring, research, data management). Adopting a network-based approach to inventories worked well when the NPS undertook paleontological resource inventories for the 32 I&M networks. The network approach is also being applied to the inventory for the geologic type sections in the NPS. The planning team from the NPS Geologic Resources Division who proposed and designed this inventory selected the Greater Yellowstone Inventory and Monitoring Network (GRYN) as the pilot network for initiating this project. Through the research undertaken to identify the geologic type sections within the parks of the GRYN, methodologies for data mining and reporting on these resources was established. Methodologies and reporting adopted for the GRYN have been used in the development of this type section inventory for the Chihuahuan Desert Inventory & Monitoring Network. The goal of this project is to consolidate information pertaining to geologic type sections which occur within NPS-administered areas, in order that this information is available throughout the NPS...

Full textAbstract:
A fundamental responsibility of the National Park Service (NPS) is to ensure that park resources are preserved, protected, and managed in consideration of the resources themselves and for the benefit and enjoyment by the public. Through the inventory, monitoring, and study of park resources, we gain a greater understanding of the scope, significance, distribution, and management issues associated with these resources and their use. This baseline of natural resource information is available to inform park managers, scientists, stakeholders, and the public about the conditions of these resources and the factors or activities which may threaten or influence their stability. There are several different categories of geologic or stratigraphic units (supergroup, group, formation, member, bed) which represent a hierarchical system of classification. The mapping of stratigraphic units involves the evaluation of lithologies, bedding properties, thickness, geographic distribution, and other factors. If a new mappable geologic unit is identified, it may be described and named through a rigorously defined process that is standardized and codified by the professional geologic community (North American Commission on Stratigraphic Nomenclature 2005). In most instances when a new geologic unit such as a formation is described and named in the scientific literature, a specific and well-exposed section of the unit is designated as the type section or type locality (see Definitions). The type section is an important reference section for a named geologic unit which presents a relatively complete and representative profile.
