The Diploma´s thesis deals with the issue of comparison of recultivated areas and areas in the point of ecological succession from the viewpoint of the plant diversity of chosen hydro-ecosystems of Trebon basin, in the area of Suchdol nad Lužnicí. Mapped sandpits Cep, Cep I, Tušť a Františkov are situated in the flood plain of the river Lužnice. Local mining of sandy gravel started in 1950s and in some areas it has not finished until now. Every mining process leads to extensive damages of the landscape, which should be corrected. The aim of this thesis is to map and compare the areas on the coast of extracted sandpits where the recultivation was done with those which were left to "controlled" ecological succession.

Management in industrial family businesses in textiles, in a politically-charged Iran, tends to seek continuity through inter-generational succession. Scant research into the phases involved and the influences in this regional context means that it would be commercially advantageous to understand how such families manage the process of succession, and what these influences actually are. Thus, initially a broad literature review was conducted in the area of family business succession, to discern whether the succession process of Iranian family business is aligned with existing literature; a conceptual framework representing succession in the target group was developed; and broad influential factors on the abovementioned succession process were identified, and probed for their criticality. Subsequently, this work follows an inductive approach of constructing theoretical frameworks from looking interpretively across multiple case study findings, from company interviews where successors were male, female and joint-tenure. It initially devotes considerable attention to articulating themes of the drivers and challenges, and transition strategy, before distilling through cross-case analysis the essential influential factors and what defines the phases that a successor proceeds through, from both successor and predecessor perspectives. Finally these are discussed with a number of insights coming into focus, namely the peculiarities of: the environment given the governance issues and internationally sanctioned business conditions; the foreign education experience of English-speaking successors and their autonomy as part of their identity alongside their surpassing of the predecessor academically which drives modernisation; and trust as a clear milestone marker. Notably, the widely accepted conceptualisation of succession in four phases – initiation, integration, joint reign and withdrawal – is extended in this work to include an initial phase, priming, supported by substantive literature on affective commitment arising from parent-child relations. Further, a complex conceptual mapping of the innate phase-specific characteristics helps in the understanding of successor capacity and progress. Notwithstanding the limitations inherent from using a flexible instrument in a qualitative study across narrow business perspectives, and without claim to any single generalisation, management consultancy and practice might consider being alert to the above insights and pressures emanating from important points on the two conceptualised models. The study also has an exploratory aspect that opens up multiple avenues for further investigation into specific mechanisms within this type of transition.

abstract: The workforce demographics are changing as a large portion of the population is approaching retirement and thus leaving vacancies in the construction industry. Succession planning is an aspect of talent management which aims to mitigate instability faced by a company when a new successor fills a vacancy. Research shows that in addition to a diminishing pool of available talent, the industry does not have widespread, empirically tested and implemented models that lead to effective successions. The objective of this research was to create a baseline profile for succession planning in the construction industry by identifying currently implemented best practices. The author interviewed six companies of varying sizes and demographics within the construction industry and compared their succession planning methodologies to identify any common challenges and practices. Little consensus between the companies was found. The results of the interviews were then compared to current research literature, but even here, little consensus was found. In addition, companies lacked quantitative performance metrics demonstrating the effectiveness, or ineffectiveness, of their current succession planning methodologies. The authors recommended that additional research is carried out to focus on empirical evidence and measurement of industry practices surrounding talent identification, development, and transition leading to succession. / Dissertation/Thesis / Masters Thesis Engineering 2015

Neste cenário, a adoção do sistema de sucessão de culturas surge como uma opção conservacionista ao convencional sistema de monocultura, graças às vantagens como a melhoria das propriedades físicas, químicas e biológicas do solo, melhora o aproveitamento de fertilizantes, reduz os riscos de mercado, entre outras. Entretanto, a adoção contínua do sistema de sucessão de culturas traz malefícios ao solo, como erosão, compactação e esgotamento de nutrientes, os mesmos efeitos do uso contínuo do sistema de monocultura. O objetivo geral deste trabalho foi avaliar a rentabilidade e os riscos econômicos para a adoção do sistema de sucessão de culturas anuais (cultivos de verão seguidos de cultivos de inverno) em relação ao sistema em monocultura no estado do Mato Grosso. Como objetivos específicos, buscou-se identificar quais as principais fontes potenciais de risco para cada cultura e avaliar como elas influenciaram os resultados finais das simulações de cada sistema. Foram realizadas simulações de cenários para ambos os sistemas por meio do método de simulação de Monte Carlo e as culturas selecionadas para esta análise foram a soja, o algodão e o milho dada sua relevância para a economia local e nacional. Para cada sistema foram feitas as análises estatística, de sensibilidade e de percentis de risco utilizando os indicadores de rentabilidade renda líquida (RL) e índice de lucratividade (IL), nos cenários pessimista, médio ou de maior ocorrência e pessimista para as variáveis de produção. Os resultados das simulações indicaram que a monocultura da soja é a atividade com o desempenho mais conservador dentre as analisadas, com as menores probabilidades de prejuízos no cenário mais pessimista de valores e os mais baixos retornos prováveis nos cenários médio e otimista, a baixos níveis de risco, sendo mais indicada a produtores conservadores e avessos a assumirem elevados riscos. A monocultura do algodão e a sucessão de culturas soja-algodão apresentaram os maiores prejuízos no cenário pessimista e as maiores probabilidades de retornos econômicos no cenário otimista, mas com elevados níveis de risco, sendo mais indicados a produtores dispostos a assumirem elevados riscos. A sucessão soja-milho apresentou relevantes resultados nos três cenários, com baixa probabilidade de prejuízos no cenário pessimista e alto retorno econômico nos cenários médio e otimista, a níveis médios de risco, sendo indicada para produtores que estão dispostos a assumirem níveis de riscos mais elevados do que os produtores conservadores. Além disso, as fontes de risco mais impactantes nos resultados das simulações de cenários de ambos os sistemas foram os preços de venda da soja e da pluma de algodão, ambas com impacto positivo, e os custos do inseticida do algodão e do fertilizante da soja, ambas com impacto negativo. No geral, o sistema de sucessão de culturas apresentou maiores resultados a menores níveis de risco. / One of the greatest challenges of agricultural producers is to raise production levels and productivity of plantations and additionally meet the yearnings of society for the production systems more sustainable. In this scenario, the adoption of the crop succession system emerges as a conservationist option front of conventional monoculture system, to the advantages as improvement of physical, chemical and biological properties of the soil, improves the use of fertilizers, reducing market risks, among others. However, the continuous adoption of the crop succession system brings harm to the ground effects, such as erosion, compaction and nutrient depletion, the same effects of the use of the monoculture system. The general goal of this research was to evaluate the profitability and the economic risks for the adoption of the crop succession system for annual crops (summer crops followed by winter crops) regarding to the monoculture system in the State of Mato Grosso. The specific goals of this study were to identify the main potential sources of risk for each culture and evaluate how they have influenced the final results of each system simulations. Scenarios were carried out for both systems by Monte Carlo simulation method and the crops selected for this analysis were soybean, cotton and maize, due to their relevance to the local and national economy. For each system the following analyses were obtained: statistical, sensitivity and percentiles of risk, using the profitability indicators, net income (NI) and profitability index (PI), for three scenarios, pessimistic, medium or higher occurrence and optimistic, for the variables of production. The results of the simulations indicated that the monoculture of soybean is the activity with the most conservative performance analyzed, with the lowest probability of losses in the pessimistic scenario and the lowest probable return on medium and optimistic ones, at low levels of risk. This case is more indicated to the conservative producers and averse to assume high risks. The cotton monoculture and the crop succession soybean-cotton presented the biggest losses in the pessimistic scenario and the greater probability of economic return in the optimistic ones, but, at high levels of risk. These cases are most suitable to producers willing to take higher risks. The soybean-maize succession presented relevant results in all scenarios, with low probability of losses in the pessimistic scenario and high economic return on medium and optimistic ones, with average levels of risk, being indicated for producers who are willing to take higher risk levels than the conservative producers. In addition, the more impactful sources of risks for monoculture and crop succession systems were the sale prices of soybeans and cotton feather, both with positive impact, and the cost of cotton insecticide and fertilizer of soybean, with negative impact. In general, the crop succession system presented higher results at lower levels of risk against the monoculture system.

Spontaneous vegetation succession in mined peatlands in the Czech Republic was studied using the space-for-time substitution approach. The study focused on the variability of vegetation in traditionally mined (block-cut) and industrially mined (milled) peatlands. The influences of age, abiotic site factors, as well as landscape factors were analysed. The thesis summarizes also the state of current knowledge on various groups of organisms (plant, algae, fungi, and animals) in the extracted peatlands in the Czech Republic. The recomendations for the ecological restoration of mined peatlands are given.

A agricultura tem tido, ao longo dos séculos, um destaque a nível mundial. O Brasil tem sido considerado grande player nesse segmento, globalmente. Dentro desta perspectiva, este trabalho teve como objetivo o estudo de caso de uma empresa familiar com atuação no agronegócio, localizada no Centro-Oeste brasileiro, em processo de sucessão. A pergunta chave foi “De que modo empresas familiares ligadas ao agronegócio, oriundas da região noroeste do Rio Grande do Sul, e instaladas na região Centro-oeste do Brasil, na busca por explorar novas terras e novas oportunidades, lidaram e estariam lidando com a sucessão em seus negócios, bem como quais seriam as características mais marcantes na condução desse processo”? Para analisar a sucessão familiar, realizou-se um estudo de caso, embasando-se através de pesquisa sobre a Empresa Familiar, Sucessão Familiar e Agronegócio, pesquisa documental, entrevistas semiestruturadas com os sucessores, sucedidos e gestores na empresa que já passaram ou estão passando por este processo. Concluiu-se que a sucessão na empresa visitada vem ocorrendo ao longo da última década, como um processo de desenvolvimento continuado dos sucessores através dos anos, primando pela manutenção dos valores da família e da empresa, de forma profissional, o que tem permitido a perpetuação da empresa, que já está na terceira geração. / Agriculture has been, over the centuries, a prominent worldwide. Brazil has been considered major player in this segment globally. Within this perspective, this study aimed to the case study of a family company engaged in agribusiness, located in the Brazilian Midwest, in succession. The key question was " How family businesses in the agribusiness , came from the Northeast region of Rio Grande do Sul , and installed in the Midwest region of Brazil , seeking to explore new lands and new opportunities , and would be dealt dealing with succession in their business , and what are the most striking features in the conduct of this process " . To analyze the family succession, there was a study case, that is basing through literature search on Family Business, Family Succession and Agribusiness, and semi-structured interviews with the successors, succeeded and managers in the company who have gone or are going through this process. It was concluded that the succession in the visited company has been occurring over the past decade, as an ongoing development process of successors over the years, striving for maintenance of family and values of the company in a professional manner, which has allowed the perpetuation the company, which is already in the third generation.

Driven by global population growth and anticipated increases in demand for food as well as a number of other goods and services, the issue of food security has recently (re-)emerged in both policy and academic contexts. Using a modified political economy perspective, this study recognises the role of the family farm as policy operatives in this context and considers the potential influence of intergenerational farm transfer on the delivery of food security objectives. It also explores how the food security agenda, described by some as the renaissance in agriculture, is influencing the farming community and in particular, the appeal of succeeding to the family farm. Broadly, it seeks to add to, and develop the body of knowledge relating to family farm succession, and explores the linkages between succession and the food security agenda. The study used 1941-1943 National Farm Survey data and maps as a tool to facilitate semi-structured interviews with farmers, and where applicable their potential successors, in Hatherleigh and surrounding parishes, Devon, UK. The study also highlights the absence of the potential successor from family farm research and subsequently resolves definitional issues surrounding the term by presenting a conceptual framework, including a definition of the potential successor. The findings indicate that family farming continues to be largely hereditary, and demonstrates how the occupancy of Hatherleigh and surrounding parishes has been shaped by traditions and expectations that socialised incumbent farmers into succeeding. Despite contemporary concern about the desirability of intergenerational farm transfer, participating farmers understood passing on the farm to a next generation as desirable. Many of whom framed their optimism in the context of the food security agenda and the anticipated opportunities for the industry. Drawing on in-depth interviews, this thesis questions the notion of the so called ‘succession crisis’, and identifies a number of positive adaptations and outcomes associated with successor identification which it discusses in the context of delivery of food security objectives. Two broad types of transfer of managerial control were identified and a typology is offered that suggests types of transfer are the product of potential successors’ ages and the subsequent nature of their upbringing. The thesis critically considers the types’ respective merits in the context of food security objectives and an original conceptualisation is offered as a contemporary way of understanding the types of transfer of managerial control in Hatherleigh and surrounding parishes. As well as influencing the transfer of managerial control, the study attributes significant differences in potential successors’ motivations according to the fundamental societal shift from a ‘society of duty’ to a ‘market place of opportunity’. Critically, the thesis revealed how, unlike their older counterparts, younger potential successors were motivated by the renaissance in agriculture, particularly elements such as the renewed public interest in, and respect for, farming as well as, opportunities farming for food security may offer. Overall, the thesis highlights the importance of considering the family farm and the influence of succession on the industry’s response to food security policy measures. It proposes that, at an aggregate level, ‘effective succession’, measured in terms of the identification of a successor and the timely and appropriate transfer of managerial control, are likely to be key factors in the delivery of food security objectives. It also recognises how succession and successor ‘creation’ are changing as society increasingly prioritises the individual and that the changing image of farming associated with the renaissance in agriculture is influencing younger potential successors. From these conclusions, suggestions are made for areas of further work, particularly with regard to understanding the implications of the different types of transfer of managerial control on long-term farm business performance, and some practical options for continuing to attract potential successors into the industry and facilitating effective intergenerational transfer are offered.

Identifying the diversity of contexts that can lead to hybridization is important for understanding its prevalence and dynamics in natural populations. Despite the potential of ecological succession to dramatically alter species co-occurrence and abundances, it is unknown whether it directly promotes hybridization and, if so, has long-lasting consequences. Here, we summarize 30 years of survey data across 10 populations to show that in western and mountain bluebirds, heterospecific pairing occurs during repeatable and transient colonization events at the early stages of species turnover. Despite mixed pairing occurring only during early succession, genetic data showed presence of hybrids at both early and late successional stages. Moreover, hybrids showed novel patterns of variation in morphology and behavior, emphasizing that even ephemeral contexts for hybridization can have important evolutionary consequences. Our results suggest that because ecological succession often brings together closely related competitors in disparate numbers but lasts for only a brief period of time, it may be a widespread but underappreciated context for hybridization.
