Ptáci v učebnicích pro ZŠ a nižší stupeň gymnázia (Analýza grafického zpracování kapitoly Ptáci se zaměřením na modelové druhy) / Birds in Textbooks for Elementary Schools and Lower Grammar Schools (Analysis of the Graphic Design of the Chapter Birds with Focused on Model Species)Vávrová, Anna January 2020 (has links)
This diploma thesis deals with the graphic processing of the chapter Birds (Aves) in natural science textbooks for teaching at elementary school or lower grammar school with a focus on the model species (hereinafter referred to as MS) used for the chapter. The focus on MS stems from the fact that the authors choose different taxa representatives from the taxon, they are not uniformly displayed or described. The theoretical part of the DT deals with the definition of a textbook and the possibilities of its analysis. In particular, research is described here, which focuses on the importance of graphic information in textbooks and misconceptions in pupils for the taxon birds. In the second part of the chapter I deal with the characteristics of the bird taxon. In the practical part of DT, my first goal is to map and analyze graphic information and its processing for the taxon birds (Aves) in natural science textbooks for primary and lower grammar school. The analysis involves the comparison of specific textbooks, the ways in which they are displayed, the ways of describing them in the text and other characteristics that relate to all general pictures that show important features of the group. Another aim of this part of DT is to describe and evaluate the MS for the bird tax (Aves), which would be...

Estudo de associação genômica ampla aplicada ao conteúdo de macronutrientes em grãos de Coffea arabica L.Felicio, Mariane Silva January 2020 (has links)
Orientador: Douglas Silva Domingues / Resumo: O café é uma das commodities agrícolas tropicais mais comercializadas no mundo. Coffea arabica é a principal espécie utilizada para a produção comercial de café. A espécie é originária da Etiópia. Ela é única espécie alotetraploide do gênero (2n = 4x = 44) e se reproduz predominantemente por autofecundação. As cultivares comerciais de C. arabica possuem baixa diversidade genética, o que indica a necessidade de introgressão de alelos de germoplasma para o melhoramento dessas cultivares. Acessos do centro de origem da espécie possuem maior diversidade que as cultivares comerciais e podem ser utilizados para a identificação de novos alelos. O conteúdo de macronutrientes em grãos do cafeeiro tem impacto direto na qualidade do produto. No entanto, a base molecular da composição mineral de grãos de cafeeiro ainda é pouco conhecida. Com isso, o objetivo desse trabalho foi identificar marcadores SNP possivelmente associados com a composição de macronutrientes em grãos de C. arabica. Para alcance deste objetivo, foram comparados três métodos de imputação de genótipos, bem como foi realizado o mapeamento associativo em estudo de associação genômica ampla (GWAS). Foi utilizado um painel de 110 genótipos de C. arabica, composto por genótipos elite do programa de melhoramento do Instituto Agronômico do Paraná (3), cultivares comerciais (11) e acessos selvagens (96). Foram realizadas análises da composição de cinco macronutrientes (N, P, K, Ca e Mg) em grãos de cafeeiro coletados de 70 e 1...

The species is originally from Ethiopia. In the Coffea genus, C. arabica is the only allotetraploid species (2n = 4x = 44) and it reproduces predominantly by self-fertilization. The commercial cultivars of C. arabica have a narrow genetic base that indicates the need for the introgression of new alleles from germplasm into coffee breeding programs. Wild accessions of C. arabica, from Ethiopia, have higher genetic diversity and can be used to identify new alleles. The macronutrient composition of the coffee grains has a direct impact on grain quality. However, the molecular basis for the mineral composition in coffee grains still poorly understood. Thus, the aim of this work was to perform mapping association analyses using the genome-wide association study (GWAS) technique to identify single nucleotide polymorphisms (SNPs) associated with macronutrient content in coffee grains from C. arabica. We also tested three imputation methods (haplotype missing allele imputation - Beagle, K-nearest neighbors, and Random Forest) in the genotypic data, and mapped it to two C. arabica reference genomes from the cultivar Caturra red and the spontaneous dihaploid Et39. We used a panel of 110 C. arabica genotypes, including elite landraces from the IAPAR coffee breeding program (3), commercial cultivars (11) and wild accessions (96). Analysis of the compositi...

Development and Application of Genomic Resources in Non-model Bird SpeciesWang, Biao January 2012 (has links)
Understanding the genetic basis of biological processes is a fundamental component of modern ecology and evolutionary biology studies. With the recent advent of next generation sequencing (NGS) technologies, it is now possible to perform large genome and transcriptome projects for ecologically important non-model species. In this thesis, I focused on the development and application of genomic resources of two non-model bird species, the black grouse (Tetrao tetrix) and the great snipe (Gallinago media). Using the chicken genome as a reference, I developed a reference guided NGS pipeline to assemble the complete draft genome of black grouse. The draft genome has a good coverage of the main 29 chromosomes of the chicken genome. The genome was used to develop a vast number of genetic markers. Comparing this genome with that of other species, I identified the genomic regions which were important for the lineage specific evolution of black grouse. I also sequenced and characterised the spleen transcriptome of the black grouse. I identified and validated a large number of gene-based microsatellite markers from the transcriptome and identified and confirmed the expression of immune related genes. Using a similar RNA-Seq approach, I also sequenced the blood transcriptomes of 14 great snipe males with different mating success. I identified genes and single nucleotide polymorphisms (SNPs) which might be related to male mating success in this species, both in terms of gene expression levels and genetic variation structure. For the immunologically important major histocompatibility complex (MHC) gene region of black grouse, I constructed a fosmid library and used it to sequence the complete core MHC region of this species. This resource allowed me to perform a comprehensive comparative genomics analysis of the galliform MHC, by which I found that some genes in this region were affected by selective forces. I was also able to develop a single locus genotyping protocol for the duplicated MHC BLB (class IIB) genes and found that the two black grouse BLB loci followed different evolutionary trajectories. This thesis set an example of developing genomic resources in non-model species and applying them in addressing questions relevant to ecology and evolutionary biology.

Identification de gènes impliqués dans la variation morphologique des fleurs entre deux espèces du genre RhytidophyllumPoulin, Valérie 08 1900 (has links)
Les adaptations florales à des pollinisateurs comme les changements de forme de la corolle
entraînent souvent un isolement reproducteur et donc la spéciation. Malgré leur importance
écologique, les mécanismes génétiques à l'origine de cette diversité de caractères sont encore mal
compris, surtout en dehors des espèces modèles. L’objectif de mon projet de maîtrise était donc
d'identifier les gènes impliqués dans la variation de la forme de la corolle entre deux espèces du
genre Rhytidophyllum (famille des Gesneriaceae), qui ont des modes de pollinisation différents.
La première, R. rupincola, a des fleurs tubulaires et est strictement pollinisée par les colibris, tandis
que la seconde, R. auriculatum, a des fleurs plus ouvertes et est pollinisée par les colibris et les
chauves-souris. Dans cette étude, nous avons fait une revue de littérature et utilisé une approche
de transcriptomique comparative pour identifier des gènes candidats qui pourraient expliquer la
variation de la forme florale entre R. auriculatum et R. rupincola. Nous avons ensuite testé leur
association avec la variation de la forme de la corolle en utilisant la cartographie de loci de traits
quantitatifs (QTLs) pour une population hybride F2. Les résultats ont montré que 7 des 29 gènes
candidats étaient associés à 8 QTLs différents. La répartition et la fonction supposée de ces gènes
suggèrent que la forme de la corolle est un trait complexe. Ce type d'étude est rarement entrepris
chez des espèces non-modèles, mais il est important afin d'intégrer la génétique du développement
floral dans une perspective évolutive. / Floral adaptations to specific pollinators like corolla shape changes often result in reproductive
isolation and thus speciation. But despite their ecological importance, the genetic mechanisms
behind this diversity of traits are still poorly understood, especially outside model species. Hence,
our goal is to identify genes involved in corolla shape variation between two species of the
Rhytidophyllum genus (Gesneriaceae family) from the West Indies, which is characterized by
shifts in pollination modes during its evolution. The first one, R. rupincola, has a tubular corolla
and is strictly pollinated by hummingbirds. The second one, R. auriculatum, has more open flowers
and is pollinated by both hummingbirds and bats. We know from previous work that the variation
in morphological floral traits between these species is explained by a few quantitative trait loci
(QTLs) of moderate to small effect (Alexandre et al., 2015), but we still do not know which genes
underly these loci. In this study, we surveyed the literature and used a comparative transcriptomic
approach to identify candidate genes that could explain floral variation between R. auriculatum
and R. rupincola. We then tested their association with corolla shape variation using QTL mapping
for a F2 hybrid population. Results showed that 7 out of 29 candidate genes were included within
8 different QTL. The number, repartition and putative function of these genes suggest that corolla
shape is a complex trait. This sort of investigation is rarely undertaken in non-model species, but
is important to integrate developmental genetics with an evolutionary perspective.
