The abstract presents an architectural proposal for the Churchill Wildlife Information and Indigenous Culture Centre in Churchill, Northern Manitoba. The project aims to create a dynamic and educational space that showcases the town's rich history, celebrates its Indigenous heritage, and emphasizes the harmonious coexistence with the diverse local wildlife. Situated at the historically significant Rocket Range site, the centre seamlessly integrates with the natural landscape, offering visitors an immersive and captivating journey. Through carefully designed teaching spaces, interactive wildlife exhibitions, and curated displays of indigenous historical photographs, art, and artifacts, the centre provides a comprehensive exploration of Churchill's cultural and environmental heritage. Sustainability and cultural exchange are core principles guiding the design approach. The centre incorporates an artist-in-residence program, facilitating hands-on demonstrations of indigenous crafts while fostering dialogue and mutual learning. With a focus on addressing the need for an updated space that accurately reflects Churchill's unique culture and history, the centre endeavours to inspire a renewed connection with the environment and indigenous traditions. By promoting appreciation, knowledge, and a sense of responsibility towards wildlife, the centre aspires to become a beacon of education and conservation in Churchill's remarkable landscape.

Objectives: High prevalence of bacterial vaginosis (BV) has been reported in lesbians but most studies were based in sexually transmitted infection clinic settings; therefore, we wished to determine the prevalence and risk factors of BV in lesbians and heterosexual women in a community setting in the UK. Methods: A cross-sectional study recruiting lesbian women volunteers from community groups, events, clubs and bars. Heterosexual women were recruited from a community family planning clinic. They self-swabbed to create a vaginal smear, which was Gram-stained and categorised as BV, intermediate or normal flora. They completed a questionnaire about age, ethnic group, smoking, genital hygiene practices and sexual history. Results: Of 189 heterosexuals and 171 lesbians recruited, 354 had gradeable flora. BV was identified in 43 (25.7%) lesbians and 27 (14.4%) heterosexuals (adjusted OR 2.45, 95% CI 1.25 to 4.82; p¿=¿0.009). Concordance of vaginal flora within lesbian partnerships was significantly greater than expected (27/31 (87%) couples, ¿¿=¿0.63; p<0.001). Smoking significantly increased the risk of BV regardless of sexuality (adjusted OR 2.65; p¿=¿0.001) and showed substantial concordance in lesbian partnerships but less than for concordance of flora. Conclusions: Women who identified as lesbians have a 2.5-fold increased likelihood of BV compared with heterosexual women. The prevalence is slightly lower than clinic-based studies and as volunteers were recruited in community settings, this figure may be more representative of lesbians who attend gay venues. Higher concordance of vaginal flora within lesbian partnerships may support the hypothesis of a sexually transmissible factor or reflect common risk factors such as smoking.

Yes / Despite more than two centuries of almost uninterrupted surveys and studies of Algerian lichenology, the history and lichen diversity of Algeria are still poorly understood. During the preparation of a forthcoming checklist of Algerian lichens it was considered necessary to provide the present historical overview of lichenological exploration of the country from 1799 to 2013, supported by a reasonably comprehensive annotated bibliography of 171 titles.

The purpose of this study was to explore perceptions of flora poaching among conservation officers, park rangers and botanists within Central Appalachia. Though some work has sought to understand poaching in other forms, such as animal poaching, little is known regarding the poaching of plants. This is especially true within the Appalachian Region. Several research questions were explored in this study, including the types of flora being poached, the characteristics of poachers, poaching tactics utilized, and deterrence measures that are currently in place. Data were collected through semi-structured interviews with 20 individuals working in the field. Findings contribute to the existing literature surrounding poaching, which can aid conservation efforts across the Appalachian Region.

O principal objetivo deste trabalho é o levantamento e estudo taxonômico das espécies das tribos Crotalarieae (Benth.) Hutch. e Genisteae (Bronn) Dumort. de Leguminosae-Papilionoideae, que ocorrem na Serra do Cipó, Minas Gerais. A Serra do Cipó está localizada na porção sul da Cadeia do Espinhaço, um conjunto de elevações que se estende por cerca de 1000 km na direção Norte-Sul, entre os estados de Minas Gerais e Bahia. Inserida no Domínio do Cerrado, a Serra do Cipó apresenta os campos rupestres como o principal tipo vegetacional, associados aos afloramentos rochosos e solos litólicos encontrados nas áreas mais altas das serras. Os campos rupestres mineiros estão frequentemente entremeados por fitofisionomias de cerrado, matas ciliares, capões de mata e brejos estacionais ou perenes. Expedições a campo e levantamento dos principais herbários que abrigam coleções da região, levaram ao reconhecimento de 18 espécies, pertencentes a 2 gêneros dos grupos estudados: 16 espécies de Crotalaria L. (Crotalarieae), e de 2 espécies de Lupinus L. (Genisteae). O capitulo 1 da dissertação compreende o levantamento das espécies e o seu estudo taxonômico segundo o modelo da Série Flora da Serra do Cipó, contendo chaves de identificação, descrições morfológicas e ilustrações dos gêneros e espécies, além de comentários sobre sua distribuição geográfica, fenologia e variabilidade, editados no formato da publicação. O capitulo 2 trata de um estudo de anatomia foliar realizado com as 16 espécies de Crotalaria que ocorrem na área estudada, com o objetivo de levantar caracteres que possam auxiliar na circunscrição das espécies. Esse estudo utilizou amostras de folhas obtidas de material herborizado e técnicas usuais em anatomia vegetal, incluindo análises em microscopia de luz e microscopia eletrônica de varredura. Muitos dos caracteres analisados mostraram-se relativamente uniformes, no entanto alguns deles revelaram-se úteis no diagnóstico de espécies. Destacam-se dentre estes alguns caracteres relacionados à textura, a aspectos de venação, tais como a formação de aréolas e modo de inserção das nervuras secundárias à nervura mediana, e principalmente à epiderme / The main goal of this study is to provide a taxonomic survey of the tribes Crotalarieae (Benth.) Hutch. and Genisteae (Bronn) Dumort. (Leguminosae-Papilionoideae) in the Serra do Cipó, Minas Gerais. The Serra do Cipó is located in the southern portion of the Espinhaço range of mountains, which extends for about 1000 km in north-south direction, from the state of Minas Gerais to the state of Bahia. The Serra do Cipó belongs to the Cerrado Domain, and its main vegetation type is the Campo Rupestre, a mostly herbaceous formation with scattered shrubs and treelets on litholic or sandy soils around rocky outcrops,found in higher areas of the mountains. On lower elevations other phytophysiognomies are found, mostly patches of savannahs formations (cerrados and cerradões), gallery forests, montane forests and swamps. Field expeditions and the examination of herbarium collections led to the recognition of 16 species of Crotalaria L. (Crotalarieae), and 2 species of Lupinus L. (Genisteae) in the area. The first chapter of the dissertation comprises a taxonomic survey of the species of these two genera occurring in the Serra do Cipó. It contains keys for identification, morphological descriptions and illustrations of the species, and comments on their geographical distribution, phenology and morphological variation. The second chapter presents an anatomical study of leaves of 16 species of Crotalaria occurring in the Serra do Cipó, aiming to provide additional characters for the circumscription of the species. Leaf samples were obtained from herbarium specimens and standard techniques in plant anatomy were used, including light microscopy and scanning electron microscopy. Many of the characters analyzed were non-informative, but the following ones were useful to recognize several species: characters related to lamina texture, to the epidermis, and to the venation pattern, specially the formation of areoles and mode of insertion of the secondary veins to midvein

Samples were collected in the municipality of Santa Luzia do Paruá, in the Alto Turi region, which belongs to the Amazon region, in the state of Maranhao. The objective of this study was to recognize the phytogeographic and chemical profile of the Melipona geopropolis samples and to help characterize the resin supplying vegetation for these bees. The geopropolis samples were collected monthly from December/2013 to December/2014 from nests kept in wooden boxes in a particular meliponary. The palynological analysis was done according to the standard methodology proposed by Barth (1998). The chemical profile of the samples was determined by high performance liquid chromatography (CLAE), liquid chromatography coupled to mass spectrometry (LC-MS) and gas chromatography coupled to mass spectrometry (GC / MS) analysis. And also included quantification of the content of total polyphenols (TPT) through the use of Folin-Ciocalteau reagents and sodium carbonate 20%; total flavonoids (TFT) by the photocolorimetric method with methanolic solution of aluminum chloride (AlCl3) 5%, and the antioxidant activity of the hydroalcoholic extracts of geopropolis by the DPPH free radical assay (Brand-Williams et al). A total of 148 pollen types were identified, distributed in 49 families, 108 genera and two unidentified types. In the geopropolis samples of M. subnitida 107 pollen types were distributed in 40 families and 72 genera. In the M. seminigra, 93 pollen types, 37 families and 70 genera were observed. For M. flavolineata were 98 pollen types, belonging to 33 families and 72 genera. In M. fasciculata there were 64 pollen types, 28 families and 53 genera, being therefore the one with the lowest pollen richness in the samples. Fabaceae presented the highest richness of pollen types (39 types), followed by Rubiaceae (11 types). The pollen types most common to Melipona species were: Attalea speciosa, Anacardium, Borreria verticilatta, Baccharis, Clusia, Chamaecrista, Croton, Euterpe/Syagrus, Eucalyptus, Hyptis, Mauritia, Mimosa pudica, M. caesalpinaefolia, Mouriri, Myrcia /Psidium, Protium And Symphonia globulifera, which characterized the phytogeographic profile of the geopropolis of this region. Aniardium, Ardisia, Baccharis, Caryocar, Clusia, Clusia grandiflora, Eucalyptus, Eupatorium, Hyptis, Myrcia/Psidium, Platonia insignis, Protium, Spondias, Symphonia globulifera, Tapirira and Vismia were the possible resin species suppliers for the Melipona geoprópolis . The presence of various compounds which have been tentatively characterized as quinic acid, benzophenone derivatives, O-glycosylated flavonoid and xanthones have been disclosed. The mangiferin compound was present in all samples. It was also verified the presence of benzophenones that appear to be involved in the biosynthesis of glycosylated xanthones. The extracts presented flavonoid contents above 2%, which allows them to be classified according to Brazilian legislation as a geopropolis with a high content of flavonoids. For the antioxidant activity a variation of 2.20 to 44.35% occurred. There was a variation in the content of phenolic compounds and flavonoids among the different samples of the four Melipona species analyzed. The results indicate that the bee species and the collection season, as well as the interaction between these factors, influence the concentration of bioactive compounds in the geopropolis. Thus, we believe that the results obtained contribute significantly to the geopropolis characterization of stingless bees from Amazonia Maranhense and show the importance of expanding the studies of chemical characterization and standardization of product quality parameters, since thisis a rich source of bioactive compounds with great pharmacological potential. / Analisou-se o espectro polínico de cento e trinta amostras de geoprópolis das seguintes espécies de Melipona: M. fasciculata, M. flavolineata, M. seminigra e M. subnitida. As amostras foram coletadas no município de Santa Luzia do Paruá, na região do Alto Turi, que pertence ao domínio amazônico, do estado do Maranhão. Este estudo teve como objetivo reconhecer o perfil fitogeográfico e químico de amostras da geoprópolis de Melipona e auxiliar na caracterização da vegetação fornecedora de resina para estas abelhas. As amostras de geoprópolis foram obtidas mensalmente de dezembro/2013 a dezembro/2014 a partir de ninhos mantidos em caixas de madeira em meliponário particular. A análise palinológica foi feita de acordo com a metodologia padrão proposta por Barth (1998). O perfil químico das amostras foi determinado por meio das análises de cromatografia líquida de alta eficiência (CLAE), cromatografia líquida acoplada a espectrometria de massa (CL-EM) e cromatografia gasosa acoplada a espectrometria de massa (CG/EM). Também foram quantificados o teor de polifenóis totais (TPT), por meio do uso dos reagentes Folin-Ciocalteau e carbonato de sódio a 20%; de flavonoides totais (TFT) por meio do método fotocolorimétrico com solução metanólica de cloreto de alumínio (AlCl3) a 5%, e da atividade antioxidante dos extratos hidroalcoólicos de geoprópolis pelo ensaio do radical livre DPPH (Brand-Williams et al. 1995). Foram identificados 148 tipos polínicos, distribuídos em 49 famílias, 108 gêneros e dois tipos não identificados. Nas amostras de geoprópolis de M. subnitida identificou-se 107 tipos polínicos distribuídos em 40 famílias e 72 gêneros. Nas de M. seminigra foram observados 93 tipos polínicos, 37 famílias e 70 gêneros. Para M. flavolineata foram 98 tipos polínicos, pertencentes a 33 famílias e 72 gêneros. Já em M. fasciculata foram 64 tipos polínicos, 28 famílias e 53 gêneros, sendo, portanto, a que apresentou menor riqueza de pólen nas amostras. Fabaceae apresentou a maior riqueza de tipos polínicos (39 tipos), seguida de Rubiaceae (11 tipos). Os tipos polínicos mais comuns às espécies de Melipona foram: Attalea speciosa, Anacardium, Borreria verticilatta, Baccharis, Clusia, Chamaecrista, Croton, Euterpe/Syagrus, Eucalyptus Hyptis, Mauritia, Mimosa pudica, M. caesalpinaefolia, Mouriri, Myrcia/Psidium, Protium e Symphonia globulifera, que caracterizaram o perfil fitogeográfico da geoprópolis dessa região. Enquanto Anacardium, Ardisia, Baccharis, Caryocar, Clusia, Clusia grandiflora, Eucalyptus, Eupatorium, Hyptis, Myrcia/Psidium, Platonia insignis, Protium, Spondias, Symphonia globulifera, Tapirira e Vismia foram as possíveis espécies vegetais fornecedoras de resina para a geoprópolis de Melipona. Revelou-se a presença de vários compostos, que foram tentativamente caracterizados como ácido quínico, derivados de benzofenonas, flavonoide O-glicosilado e xantonas. O composto mangiferina esteve presente em todas as amostras. Também foi verificada a presença de benzofenonas que parecem estar envolvidas na biossíntese de xantonas glicosiladas. Os extratos apresentaram teores de flavonoides acima de 2% que permitem classificá-los, de acordo com a legislação brasileira como geoprópolis com alto teor de flavonoides. Para a atividade antioxidante ocorreu uma variação de 2,20 a 44,35%. Houve uma variação no teor de compostos fenólicos e flavonoides entre as diferentes amostras das quatro espécies de Melipona analisadas. Os resultados obtidos indicam que a espécie de abelha e a época de coleta, bem como a interação entre esses fatores, influenciam a concentração de compostos bioativos na geoprópolis. Desta forma, acreditamos que os resultados obtidos contribuem significativamente para a caracterização da geoprópolis das abelhas sem ferrão proveniente da Amazônia Maranhense e evidenciam a importância de ampliarmos os estudos de caracterização química e padronização dos parâmetros de qualidade do produto, visto que este constitui uma rica fonte de compostos bioativos com grande potencial farmacológico.

La flore microbienne est un ensemble de micro-organismes comme les bactéries, archées, eucaryotes inférieurs et virus, jouant un rôle important dans l’équilibre d’un écosystème. Cette flore reste encore mal définie car en 2012, seules ~30% des micro-organismes de la flore intestinale humaine étaient caractérisés, et moins de 50% des micro-organismes de la flore fromagère traditionnelle étaient caractérisés au niveau fonctionnel. Depuis 2006, les séquenceurs à ADN de seconde génération permettent d’analyser directement le contenu génique d’un prélèvement de flore sans contrainte d’isolement ou de culture. Toutefois, les séquences d’ADN générées ne sont pas structurées en génome et sont hautement fragmentées, freinant considérablement l’analyse et l’exploitation de ces données. Dans ce travail, nous avons développé de nouvelles méthodes dites de métagénomiques quantitatives, car elles permettent de regrouper les courtes séquences d’ADN ayant la même abondance au sein de plusieurs échantillons métagénomiques, pouvant provenir d’une même espèce microbienne.Au niveau du microbiote intestinal humain, nous avons structuré un catalogue de 3,9 millions de gènes de la flore intestinale humaine en 741 unités ou « clusters » correspondant à des génomes de bactéries, d’archées et d’eucaryotes, que nous appelons espèces métagénomiques (MGS) et 6640 unités correspondant principalement à des génomes de virus, plasmides et divers ilots génomiques comme des CRISPR, que nous appelons unités métagénomiques (MGU). Cette méthode de structuration a ensuite été utilisée pour faciliter des analyses d’associations de la composition de la flore intestinale avec des maladies humaines comme la maladie de Crohn, l’obésité ou le diabète de type 2. Enfin, au niveau des flores alimentaires, nos méthodes ont été utilisées pour constituer un catalogue de 134 génomes d’espèces bactériennes fromagères et caractériser la flore de surface de fromages traditionnels. Ceci nous a permis de détecter la présence de nouvelles bactéries alimentaires, pouvant enrichir la liste des bactéries à possible intérêt technologique dans les produits laitiers fermentés. / The microbial flora is a micro-organism complex containing for example bacteria, archaea, lower eukaryotes and viruses, which play an important role in ecosystem equilibrium. This flora remains poorly defined as in 2012, only ~30% of the intestinal flora micro-organisms have been characterized, and less than 50% of traditional cheese floras were characterized at the functional level. Since 2006, the second generation of DNA sequencers have allowed the direct analysis of the genetic content from a microbial flora sample without isolation or culture limitation. However, the DNA reads generated are not structured with respect to genomes and also are highly fragmented, slowing down dramatically the exploitation and analysis of these data.In this work, a new methodology based on quantitative metagenomic are described., This allows the clustering of short DNA sequences with the same abundance in multiple metagenomic samples, which should originate from the same microbial species. A 3.9 million gene catalog has been built from the human intestinal tract microbiota and divided into 741 units or clusters corresponding to bacteria, archaea and eukaryote genomes. These have been defined as metagenomic species (MGS) and 6640 units of them corresponds mainly to viral genomes, plasmids and genetic islands like CRISPR, with the sub-name of metagenomic units (MGU). This methodology was then used to facilitate the association analysis of the intestinal flora composition with human diseases such as Crohn’s disease, obesity or type 2 diabetes. Within, the alimentary flora, our methods have also been used to constitute a 134 genomic catalog of cheese bacteria and characterize them from the surface of traditional cheeses. This allowed the detection of new alimentary bacteria, that will enriched the list of bacteria with potential interest for the commercial exploitation of fermented products.

Along with the Environmental Law, the Legal Reserve - in order to fulfill the Property Social Role ¿ allows rural landowners to make good use of natural resources and still preserve the environment in a rational way, besides providing shelter for the native flora and fauna of the region where it is located. Among important legal and environmental functions to the efficiency of environmental preservation, the lack of incentives ¿ which benefit rural producers from voluntarily establishing the institution of Legal Reserve ¿ is one of the factors that prevent an environmental reserve from existing in the majority of the rural properties within the national territory. Thus, it is essential that producers and people in general realize the importance of the Legal Reserve in rural properties, where the natural resources are preserved for present and future generations of Brazil. / Este estudo trata a Reserva Legal como um dos componentes mais importantes para a preservação dos recursos naturais de nosso país. Engajada ao Direito Ambiental, para cumprir com a função Social da Propriedade, a Reserva Legal permite que o proprietário rural usufrua dos recursos ali presentes e ainda preserve o meio ambiente de forma racional ¿ além de proporcionar abrigo para a flora e fauna nativa da região em que a mesma se encontra. Em meio a funções ambientais e jurídicas importantes para que a preservação do meio ambiente seja eficaz, a falta de incentivos que beneficiem o produtor rural para implantar, de maneira voluntária, a instituição da Reserva Legal é um dos fatores que impedem atualmente que haja uma reserva ambiental na maioria das propriedades rurais existentes no território nacional. Desta forma, é imprescindível que os produtores e as pessoas em geral percebam a importância da Reserva Legal na propriedade rural, onde os recursos naturais sejam preservados para as gerações presente e futura de nosso país.

Orientador: Eduardo Custódio Gasparino / Resumo: As abelhas Apis mellifera L. (1758) são consideradas os principais polinizadores das plantas com flores e também uma das espécies mais produtoras de mel. Devido o amplo número de espécies vegetais que utilizam para a obtenção de alimento e matéria-prima, a identificação botânica do mel é fundamental para a classificação da florada em monofloral ou silvestre. Para isso, a técnica da melissopalinologia utiliza da análise das características morfológicas externas dos grãos de pólen presentes no mel. O presente estudo objetivou analisar o comportamento estacional de forrageamento de colmeias de Apis mellifera por meio da identificação dos tipos polínicos nectíferos e poliníferos presentes no mel. As coletas do mel foram realizadas entre outubro de 2017 a agosto de 2018 nas estações primavera, verão, outono e inverno no Setor de Apicultura da Faculdade de Ciências Agrárias e Veterinárias, FCAV/UNESP Campus de Jaboticabal, São Paulo, Brasil onde três colmeias de abelhas Apis mellifera estavam instaladas. Para a extração dos grãos de pólen e montagem das lâminas a metodologia clássica da melissopalinologia e a técnica clássica de acetólise foram empregadas. Ao todo, foram encontrados 42 tipos polínicos, distribuídos em 24 famílias botânicas. Alguns tipos foram observados em todas as estações: Alternanthera (Amaranthaceae), Cecropia (Urticaceae), Mimosa (Fabaceae) e Myrtaceae (Myrtaceae), mas também houve a ocorrência de tipos exclusivos das estações: Aloe, Bignoniaceae, Byrsonima, D...

Because of the large number of plant species they use to obtain food and raw materials, the botanical identification of honey is fundamental for the classification of flowering as monofloral or wild. For this, the melissopalynology technique uses the analysis of the external morphological characteristics of pollen grains present in honey. The present study aimed to analyze the seasonal foraging behavior of Apis mellifera hives by identifying the nectiferous and polyniferous pollen types present in honey. Honey was collected between October 2017 and August 2018 in the spring, summer, autumn and winter seasons at the Setor de Apicultura da Faculdade de Ciências Agrárias e Veterinárias, FCAV/UNESP Campus de Jaboticabal, São Paulo, Brazil where three hives of Apis mellifera bees were installed. For the extraction of pollen grains and slide assembly the classical melissopalynology methodology and the classical acetolysis technique were employed. In all, 42 pollen types were found, distributed in 24 botanical families. Some types were observed in all seasons: Alternanthera (Amaranthaceae), Cecropia (Urticaceae), Mimosa (Fabaceae) and Myrtaceae (Myrtaceae), but there were also unique types of seasons: Aloe, Bignoniaceae, Byrsonima, Daustinia, Eucalyptus, Euphorbiaceae, Machaerium, Mangifera, Pseudobombax, Sapindus, Solanum and Tabebuia in spring; An...
