Birds belonging to the orders Ciconiiformes and Phoenicopteriformes are common inmates of zoological gardens. There are 12 species of the order Ciconiiformes and 1 species of the order Phoenicopteriformes bred in the Ohrada Zoo. All these species bred in the zoo are found in the Old World chiefly. The successful breeding of mentioned species depends on detailed knowledge of their biology and on providing appropriate breeding conditions. This thesis is an effort for complete analysis of the history and the present of breeding mentioned species in the Ohrada Zoo. The main aim of this thesis was to evaluate the success of nesting of birds mentioned orders in relation to breeding conditions in the zoo according to all available data processing; and to evaluate the success of nesting season of the year 2012 according to watching nesting of the birds in mentioned year. The own watching was carried out since 9th April to 30th June 2012. There are 6 species in this zoo which breed successfully regularly: the Cattle Egret (Bubulcus ibis), the Little Egret (Egretta garzetta), the Black-crown Night-heron (Nycticorax nycticorax), the Glossy Ibis (Plegadis falcinellus), the Eurasian Spoonbill (Platalea leucorodia) and the Greater Flamingo (Phoenicopterus ruber roseus). One species ? the Black Stork (Ciconia nigra) bred for the very first time in this zoo in 2012. Especially successful is the Greater Flamingo breeding in the Ohrada Zoo. The Eurasian Spoonbill, The Black-crown Night-heron, the Glossy Ibis and the Cattle Egret breeding is successful in relation to breeding conditions in this zoo, too. The nesting season of the year 2012 was exceptionally successful for the Cattle Egrets, the Eurasian Spoonbills and the Glossy Ibises, on the contrary this nesting season was not very successful for the Little Egrets.

The aim of the thesis was the appraisal of Great Crested Grebe (Podiceps cristatus) nesting biology aspects in relation to environmental conditions. The research took 6 months from the 2nd of April to the 2nd of October in 2013 and was realised in the Naděje fishpond system on the ponds Víra, Láska, Skutek, Dobrá Vůle, Rod and Naděje. This fishpond system is situated in CHKO Třeboňsko nearby villages Frahelž and Klec and it consists of total of 15 ponds which are used for intensive fish farming, partly for breeding of Wild Ducks for hunting purposes. The counting of birds, active searching of nests and measuring parameters of nests and eggs were carried out during the work. The nests were found on ponds Naděje, Skutek and Láska. In 2013 18 nests were measured altogether. On the fishpond Naděje 8 nests were situated, on the fishpond Láska 4 nests and on the fishpond Skutek 6 nests altogether. 13 nests of the total were found on a free water surface and 5 nests were situated in the vegetations of the Great Reedmace (Typha latifolia) at a maximum distance of 1 m from the free water surface. In 2013 64 eggs were measured altogether. On the fishpond Naděje parameters of 33 eggs were obtained, on the fishpond Láska 17 eggs and on the fishpond Skutek 14 eggs were found altogether.

The diploma thesis is focused on avian domestication and represents a complete summary of existing studies and knowledge on this topic. Domestication is a long-term process which occurs for thousands of years but its consequences are often overlooked. Without any doubts the impact of domestication on the animals is significant and there are several hypothesis presented in the related studies. Considerable part of the studies have shown the ultimate and proximate control, which is responsible for influence of the biology of the Zebra Finch (Teaniopygia guttata). Usually, the comparison of data, which was collected under the same conditions for the wild and exhibition type, was the weak spot of these studies. Theoretical part gathers some of the most important theories related to this issue. Some of them have been used in the own experiment, which took place in my private facility. Therefore, the aim of this study is to prove or disprove particular hypothesis based on the breeding of the Zebra Finch (Taeniopygia guttata). The research took two years and according to the data, the type influences biology of these birds. The results shows that the main factor responsible for nest building, egg size, egg weight, chick weight and the fledging period is the type.

Nos problemas de corte de itens irregulares, temos um conjunto de itens menores que devem ser alocados em objetos maiores (recipientes) de forma que estes estejam inteiramente contidos no recipiente e não se sobreponham. Neste trabalho, resolvemos um problema de corte e empacotamento de uma indústria que confecciona aventais e forros de luva, no qual deseja-se alocar uma lista de itens dentro de recipientes retangulares utilizando a menor quantidade de recipientes possível e minimizando o comprimento utilizado em cada recipiente. Para isto, utilizamos métodos exatos e heurísticos adaptados para o corte de aventais e forros de luva, com o objetivo de obter soluções de alta qualidade. Foram realizados experimentos computacionais que comprovaram a eficiência dos métodos de solução presentes neste trabalho. / In nesting problems, we have a set of small items that must be allocated into larger objects (containers) so that they are fully contained within the container and do not overlap. In this work, an apron and gloves lining industry cutting problem is solved, in which we want to allocate a list of items into rectangular containers using the smallest quantity of containers and minimizing the length used in each container. For this, we used exact and heuristic methods adapted for cutting aprons and glove liners, in order to obtain high quality solutions. Computational tests were performed and they show the efficiency of the solving methods presented in this work.

CoordenaÃÃo de AperfeÃoamento de Pessoal de NÃvel Superior / O objetivo desta tese foi estudar a estrutura da comunidade de abelhas que nidificam em cavidades preexistentes em resquÃcios de Mata AtlÃntica na regiÃo do maciÃo de Baturità â CearÃ. Para tanto foram verificados a ocupaÃÃo e emergÃncia de abelhas que nidificam em ninhos-armadilha, bem como avaliados os aspectos sobre a estrutura dos ninhos, razÃo sexual, mortalidade, preferÃncia por diferentes tipos de substratos e diÃmetros alÃm da presenÃa de inimigos naturais dessas espÃcies, em quatro Ãreas da regiÃo, visando sua utilizaÃÃo em programas de manejo de polinizaÃÃo. As amostragens foram realizadas utilizando trÃs tipos de ninhos-armadilha: gomos de bambu secos, tubos de cartolina e caixas racionais. Nas quatro Ãreas de mata serrana Ãmida estudadas foram ocupados 34 ninhos artificiais pelas abelhas. Foram amostradas seis espÃcies de abelhas nidificantes, distribuÃdas em cinco gÃneros (Centris, Mesocheira, Euglossa, Megachile e Coelioxys) e duas famÃlias (Apidae e Megachilidae). Do total de ninhos registrados com emergÃncia foram obtidos 139 indivÃduos, sendo 131 abelhas e 8 coleÃpteros. Nos 34 ninhos de abelhas obtidos, foram construÃdas 162 cÃlulas de cria, com o nÃmero de cÃlulas por ninho-armadilha variando de 1 a 13 cÃlulas de cria e o comprimento desses ninhos variando de 2,4 a 14 cm. Treze ninhos foram parasitados por himenÃpteros (Apidae e Megachilidae) e coleÃpteros (Meloidae), resultando em uma taxa de parasitismo de 38,2 % do total de ninhos fundados. AlÃm disto, ocorreu mortalidade por causas desconhecidas em 29,4 % dos indivÃduos, antes de chegar na fase adulta. As abelhas nidificaram nos trÃs tipos de ninhos-armadilhas oferecidos, sendo os gomos de bambu os mais utilizados pelas espÃcies de abelhas para a construÃÃo de seus ninhos (p < 0,05), correspondendo a 82% do total utilizado. As abelhas revelaram uma maior preferÃncia de nidificaÃÃo em orifÃcios com diÃmetros menores. Conclui-se, que os dados apresentados sÃo importantes para realizaÃÃo de prÃticas que objetivem a manutenÃÃo e conservaÃÃo dessas espÃcies, podendo tambÃm serem Ãteis para serviÃos de polinizaÃÃo de plantas nativas e agrÃcolas da regiÃo. / The aim of this thesis was to study the structure of the community of bees which nest in pre-existing cavities in remnants of Atlantic Forest of MaciÃo de Baturità - CearÃ. Therefore, it was verified the occupation and emergency of bees which nesting in trap-nests and assessed the aspects of the structure of such nests, sex ratio, mortality, preference for different kinds of substrates and diameters besides the presence of natural enemies of these species in four areas of the region, aiming their use in pollination management programs. The samples were carried out using three types of trap-nests: buds of dried bamboo, cardstock tubes and rational boxes. In the four areas of humid mountain forest studied were occupied 34 artificial nests by bees. Six species of nesting bees were sampled, distributed in five genera (Centris, Mesocheira, Euglossa, Megachile and Coelioxys) and two families (Apidae and Megachilidae). Out of the total of nests recorded with emergency it was obtained 139 individuals, being 131 bees and 8 coleopterans. In the 34 nests obtained, 162 bee brood cells were built, with the number of cells per nest-trap ranging from 1 to 13 brood cells and the length of these ranging from 2.4 to 14 cm. Thirteen nests were parasitized by hymenopterans (Apidae and Megachilidae) and coleopterans (Meloidae), resulting in a parasitism rate of 38.2% of nests founded. In addition, mortality has occurred from unknown causes in 29.4% of subjects before reaching adult stage. The bees nested in the three types of traps available, being buds of dried bamboo the most widely used by the species of bees to build their nests (p <0.05), corresponding to 82% out of the total used. The bees showed a greater preference for nesting into holes with smaller diameters. It is concluded that the data presented are important for the performance of practices that aim at maintenance and conservation of these species, and may be useful for pollination services of native and agricultural plants of that region.

Estas áreas estão sujeitas a inundações periódicas sendo possível visualizar uma estrutura espacial em mosaico relacionada a distintas condições de inundação. Os insetos residem de forma permanente nas marismas sendo o grupo mais diversificado e mais abundante e considerados consumidores secundários nestas áreas. Uma elevada riqueza de Formicidae é observada nesses ambientes. Invertebrados terrestres residentes em ecossistemas periodicamente inundados requerem estratégias especiais de sobrevivência como a migração vertical. As formigas apresentam dietas alimentares muito diversificadas e exploram constantemente o solo e a vegetação em busca de alimento, sendo, frequentemente, atraídas por iscas. O objetivo do estudo foi Investigar a composição de espécies de três comunidades de formigas, ao longo de um ciclo anual, nas diferentes zonas de alagamento de marismas, assim como avaliar dois tipos diferentes de iscas atrativas em relação às espécies de formigas capturadas nas marismas do estuário da Lagoa dos Patos, Rio Grande, RS, Brasil. As coletas foram realizadas entre julho de 2011 e julho de 2012, na Ilha da Pólvora, Ilha da Torotama e Molhe Oeste da Barra de Rio Grande. Em cada área foram demarcadas seis transecções, ao longo das quais foram dispostas dez iscas (cinco de cada tipo). As iscas foram acondicionadas em envelopes de papel laminado e expostas por 60 minutos. Foram calculadas as frequências relativas e a constância faunística das espécies amostradas (constante, acessória e acidental). As espécies foram classificadas em três grupos de acordo com seus hábitos alimentares segundo uma análise de agrupamento por similaridade. A análise da significância das diferenças entre os grupos definidos na análise de agrupamento e o teste de hipóteses sobre as diferenças na distribuição das espécies entre os pisos da marisma foram calculados através de uma análise de semelhanças ANOSIM (one way). Para verificar a existência de relação entre a frequência das espécies e o nível de alagamento da lagoa foi realizada uma análise de correlação linear simples. Foram capturadas 47.661 formigas e 34 espécies, sendo 33 atraídas por sardinha e 28 por mel. A Ilha da Torotama e o Molhe Oeste da Barra demonstraram diferenças nos hábitos de forrageio das espécies. Foi observada, em média, uma maior preferência das espécies pela isca de sardinha na Ilha da Pólvora e no Molhe Oeste da Barra. Para a Ilha da Torotama não houve diferença na preferência pelas iscas. O piso alto das marismas exibiu 31 espécies, o médio 29 e o baixo, 18. O Molhe Oeste da Barra apresentou o maior número de espécies no piso baixo, 17. Não houve diferença significativa entre os pisos e entre as áreas, embora exista certo grau de dissimilaridade. As espécies que habitavam os pisos mais baixos exibiam estratégias de nidificação para residirem nesses locais. A riqueza de espécies presentes nessas áreas demonstra a importância desses ambientes. / Salt marshes ecosystems develop in the intertidal zone from protected coasts and they have plant communities dominated by herbs. These areas are susceptible to periodic flooding, which result in a mosaic-like spatial structure related to distinct flooding conditions. Insects are permanent residents of salt marshes and represent the most diversified and abundant group, and most are considered secondary consumers. These environments present an elevated richness of Formicidae. Terrestrial invertebrates living in periodically flooded ecosystems require special survival strategies such as vertical migration. Ants show quite diversified diets and they frequently explore the soil and vegetation searching for food, thus, they can be attracted by baits. The aim of the present study was to investigate the species composition of three ants’ communities, along an annual cycle, in the different flooding zones from three salt marshes. Additionally two different types of ant baits were evaluate concerning their attractively in the salt marshes of Patos Lagoon estuary, Rio Grande, RS, Brazil. The samplings were carried out between July, 2011 and July, 2012, in the sites of Pólvora Island, Torotama Island and Molhe Oeste (jetties in the estuarine mounth). There were delimited in each site, six transects were located and in each transect. Ten baits (five of each type) were distributed. The baits were packaged into laminated paper foil and exposed for 60 minutes. The relative frequencies and constancy criteria of the sampled species were calculated (constant, accessory and accidental). The species were classified into three groups according to their feeding habits following a grouping analysis by similarity. The significance analysis of the differences between the groups defined in the cluster analysis and the hypothesis test on the differences in the species distribution between the salt marshes strata were calculated by an analysis of similarity ANOSIM (one way). Intending to verify the presence of a relation between the species frequencies and the lagoon flooding level, there was realized a simple linear correlation. There were captured 47.661 ants within 34 species and, from these, 33 were attracted by sardine and 28 by honey. Torotama Island and East Breakwater have shown differences in the species foraging habits. There was observed in average a higher preference by the species for the sardine bait in Pólvora Island and East Breakwater. Regarding Torotama Island, there was no difference in the preference by the baits. The high stratum of salt marshes exhibited 31 species, the middle, 29, and the low, 18. The East Breakwater evinced 17 species, which was the highest number in the low stratum. No significant difference was observed among the strata and the areas, although there was a certain degree of dissimilarity. The species have chosen the high stratum as favorite and the species inhabiting lower strata evinced nesting strategies to reach these spots. The diversity of species living in these areas evinces the importance of these environments.

A maioria da população desconhece a contribuição desses indivíduos como polinizadores e inimigos naturais de insetos praga, e visualizam apenas o risco das ferroadas que motivam a destruição das colônias. Dentre as espécies enxameantes, o gênero Apoica é incomum por exibir comportamento de forrageio noturno e por apresentar ninhos compostos por um único favo descoberto e construído diretamente sobre o substrato, com ausência de pedúnculo. A espécie Apoica pallens é comum no Estado de Minas Gerais e devido a escassez de informações, este trabalho visou ampliar os conhecimentos sobre a espécie, caracterizando as atividades de forrageio, as presas capturadas, a produtividade das colônias e os substratos utilizados para fundação das colônias. Os resultados demonstram que a atividade de forrageio da espécie, compreende uma amplitude de 12 horas. Dentre as presas coletadas, mais de 90% pertencentes foram lagartas de lepidóptera. A dissecação dos ninhos revelou que as células produtivas encontravam mais concentradas na região central e a média da razão encontrada entre o número de adultos produzidos por célula e o número total de células do foi de 0,62, demonstrando uma baixa utilização das células para produção de adultos. As colônias foram mais encontradas em locais com menor pressão antrópica e na maioria das vezes nas proximidades de um recurso hídrico, os substratos utilizados não foram específicos, destacando uma maior utilização de espécies vegetais. Os resultados encontrados compõem informações para preencher lacunas da literatura, motivando novos estudos com a espécie como alvo. / Swarm-founding social wasps are dominant in the neotropical region, and studies on these organisms allow a better understanding of the evolution of sociality. Most of the human communities don’t know about the contribution of these organisms as pollinators and natural enemies of insect pests, being only able to see the risk of accidents related to the wasps, which motivates the destruction of wasp colonies. Among the swarm founding species, the Apoica genus stands out due to its night foraging habit and to its nest architecture, composed of a single exposed comb built directly on the substrate, without a peduncle. The species Apoica pallens is commonly found in the Minas Gerais state and, due to the lack of information, this study aimed to build knowledge on the species’ foraging habits, characterizing its foraging activity, captured prey, colony productivity and nesting substrate. Results showed that the species’ foraging activity period comprehends a 12-hour amplitude. Among the captured prey, more than 90% of the samples were represented by Lepidoptera caterpillars. Nest dissection showed that productive cells were located in the nest’s center; the number of adults produced by cell/ total cell number rate was 0.62, which suggests low utilization of cells for producing adults. Colonies were found in areas with low anthropic pressure and usually near to hydric resources; the nesting substrates weren’t specific, showing a broad utilization of vegetal species. Our results make up a set of information that will fill a gap in the literature, motivating further studies on A. pallens.

The current accepted methods for assessing the effect of water temperatures on sea turtle nesting, utilizes sea surface temperatures (SST). Since Loggerhead sea turtles spend the majority of their time near the ocean floor, often below a thermocline, bottom temperature analysis should be a better estimate of actual temperature experienced by the sea turtles, therefore, correlating better to nesting events. Thermograph data sensors were placed along three reef tracts that run parallel to Broward County, Florida’s coastline, to collect bottom seawater temperatures from the year 2004 through 2006. Detrended average daily bottom temperatures were compared to detrended Loggerhead sea turtle nest counts collected by daily beach monitoring throughout the county. The comparisons confirmed that during the years 2004 and 2006, up to 29.6% of the fluctuations in sea turtle nesting can be associated to the short-term changes in bottom water temperature. r2-values of 0.2963 and 0.2948 were determined along the Broward County coastline, with p-values<0.001. No significant correlations were found in the year 2005 when bottom water temperature variations were smaller than in the other years. This evaluation shows that Loggerhead sea turtle nesting counts can be highly correlated to bottom seawater temperatures, in Broward County, Florida. Better understanding of a location’s temperature fluctuations can lead to a better management and conservation plan for the associated species and habitat.

Patterns, sequences of variables, have traditionally only been studied when morphic images of them appear as factors in words. In this thesis, we initiate a study of patterns in words that appear as subwords of words. We say that a pattern appears in a word if each pattern variable can be morphically mapped to a factor in the word. To gain insight into the complexity of, and similarities between, words, we define pattern indices and distances between two words relative a given set of patterns. The distance is defined as the minimum number of pattern insertions and/or removals that transform one word into another. The pattern index is defined as the minimum number of pattern removals that transform a given word into the empty word. We initially consider pattern distances between arbitrary words. We conjecture that the word distance is computable relative the pattern αα and prove a lemma in this direction. Motivated by patterns detected in certain scrambled ciliate genomes, we focus on double occurrence words (words where every symbol appears twice) and consider recursive patterns, a generalization of the notion of a pattern which includes new types of words. We show that in double occurrence words the distance relative so-called complete sets of recursive patterns is computable. In particular, the pattern distance relative patterns αα (repeat words) and ααR (return words) is computable for double occurrence words. We conclude by applying pattern indices and word distances towards the analysis of highly scrambled genes in O. trifallax and discover a common pattern.

Apesar de muitos trabalhos sobre diversidade estrem sendo publicados nos últimos anos, ainda existem muitas lacunas no território Brasileiro, destacando as comunidades de vespas sociais associadas à os dosséis florestais que são ainda largamente inexplorados. Os fragmentos urbanos ou Novel ecosystems estão recebendo destaque nos últimos anos devido seu papal de “refúgios” para biodiversidade. O presente estudo teve como objetivo central o levantamento das espécies de vespas sociais em um fragmento urbano, com base na riqueza encontrada foi estudado a sazonalidade da distribuição espacial das vespas durante as estações, assim como a criar de redes de interseção para o entendimento de preferencias de nidificação em man-made substrates e plantas. Para o estudo de diversidade e estratificação, forem realizadas durante 24 meses, coletas mensais utilizando os métodos de Busca Ativa, Busca por Ninhos e Armadilha atrativa, e para criação das redes de interação foram realizados 43 meses de coletas mensais utilizado metodologia de Busca por Ninhos. Foram encontradas 36 espécies de vespas de 10 gêneros, a riqueza encontrada é o decimo maior trabalho de levantamento no Brasil e quinto no estado de Minas Gerais, nenhum método utilizado foi capas de capturar todas as espécies de vespas, mostrado a necessidade de um consórcio de métodos. A estratificação mostrou uma variação ao longo das estações do ano, demostrado que as vespas utilizam o estrato dossel na época de estiagem e sub-bosque na época chuvosa, coletando espécies exclusivas para cada estrato, tendo dossel seis exclusivas e sub-bosque duas. A rede de interação abrigou 23 espécies de vespas sociais, 35 espécies de plantas e sete man-made substrates. Em ambas as redes foi encontrada assimetria, com um grande número de espécies de vespas, plantas e man-made substrates. No aspecto geral, a maioria das vespas teve baixa amplitude de sitio para nidificação, fundando de dois a quatro espécies de plantas/substratos. Os dados sugerem que as diferenças na complexidade estruturais do ambiente influenciam diretamente a estrutura da rede de interação entre vespas sociais e substratos para nidificação. Os resultados contribuem para o aumento do conhecimento sobre a riqueza das vespas sociais na região sudeste e evidencia a capacidade de forrageio vertical das vespas sociais de acordo com a estação do ano em ambientes de Novel ecosystems. / The social wasps are of great importance in forest ecosystems for their ecological role in regulating the population of other insects. Although many studies on diversity are being published in recent years, there are still many gaps in the Brazilian territory, highlighting the social wasps communities associated with forest canopies that are still largely unexplored. “Urban green areas” or Novel ecosystems are received attention in recent years due to its role of "refuges" for biodiversity. This study aimed mainly at the checklist of species of social wasps in an urban fragment, based on the wealth found was studied seasonality of the spatial distribution of wasps during the seasons, as well as create intersecting networks for the understanding of preferences nesting in man-made substrates and plants. For the study of diversity and stratification, are carried out for 24 months monthly collections using the methods of Active Search, Searching for Nests and Attractive Trap, and for creation of interaction networks were performed 43 months of monthly sampling methodology used Search for Nests. Were found 36 species of wasp of 10 genera, the wealth found is the tenth largest work of the checklist in Brazil and the fifth in the state of Minas Gerais, no method was used to capture covers all species of wasps, shown the need for a consortium of methods. The stratification showed a variation throughout the seasons of the year, showing that the wasps use the canopy layer in the dry season and undergrowth in the rainy season, collecting exclusive species for each stratum, with six exclusive for canopy and two for undergrowth. The interaction network harbored 23 species of social wasps, 35 species of plants and seven man-made substrates. In both, systems asymmetry was observed with a large number of species of wasps, plants and man-made substrates. In general appearance, most wasps had low amplitude site for nesting, founding in two to four species of plants/substrates. The data suggest that differences in environmental structural complexity directly influence the structure of the network of interaction between social wasps and substrates for nesting. The results contribute to increased knowledge about the wealth of social wasps in the southeast region and show the vertical foraging capacity of social wasps according to the season in Novel ecosystems environments.
