O espaço físico é uma das principais dimensões do nicho de uma espécie uma vez que a maneira como é utilizado determina uma série de interações ecológicas com o ambiente. No presente estudo estimou-se o tamanho da área de uso e a seleção de habitats considerando duas escalas de seleção (2a e 3a ordem) pelo veado-catingueiro (Mazama gouazoubira) na sub-região de Nhecolândia, Pantanal sul-matogrossense. Foram capturados e utilizados 3 indivíduos de veadocatingueiro nas análises. Rádio-colares VHF (telemetria convencional) e colares GPS (telemetria digital) foram utilizados para determinação das localizações dos animais. O período total de monitoramento foi de 6 meses e abrangeu o final da estação seca e início da estação chuvosa dos anos 2010-2011. A telemetria digital em um dos indivíduos monitorados (veado-controle) permitiu corrigir e simular projeções no tamanho da área dos indivíduos monitorados pela telemetria convencional. O veado-catingueiro apresentou uma área média de 73,2 ± 32,9 ha pelo método do mínimo polígono convexo considerando a correção das áreas obtidas pela telemetria VHF. Na escala de 2a ordem de seleção de habitat a categoria floresta (cordilheiras e capões de mata) foi a única selecionada positivamente pelos indivíduos analisados. A seleção foi testada através do teste do qui-quadrado de qualidade de ajustamento e utilizando o intervalo de confiança de Bonferroni. Na escala de 3a ordem, apesar de não haver diferença significativa do uso das categorias de vegetação em relação à disponibilidade, as áreas abertas como os campos e bordas de baía foram habitats importantes no que se refere à obtenção de recursos forrageiros. Concluiu-se que o veado-catingueiro é uma espécie de cervídeo que necessita de uma área relativamente pequena para suprir seus requerimentos e tem as cordilheiras e os capões de mata como habitat de suma importância no que se refere a alocação de sua área de uso. / The physique space is a major dimensions of the niche of a species as the way is used for determining a series of interactions with the ecological environment. In the present study we estimated the size of the home range and habitat selection considering two scales of selection (second and third order) by brown brocket deer (Mazama gouazoubira) in the sub-region Nhecolândia, Pantanal, Mato Grosso do Sul state. Were captured and used three individuals brown brocket deer in the analyzes. VHF radio-collars (conventional telemetry) and collars GPS (digital telemetry) were used to determine the locations of the animals. The total period of monitoring was 6 months and covered the late dry season and rainy season of the year 2010-2011. The digital telemetry from individuals monitored (control deer) allowed a simulated projections in the surface area of conventional subjects monitored by telemetry. The deer brown brocket showed an average area of 73.2 ± 32.9 ha by the minimum convex polygon method considering the correction of areas obtained by VHF telemetry. On the scale of the second order of selection forest habitat category (chains and capons of forest) was the only positively selected by the individuals analyzed. The selection was tested using the chi-square goodness of fit and using the Bonferroni confidence interval. On the scale of the third order, although no significant difference in the use of categories of vegetation in relation to the availability, open areas like fields and edges of the bay habitats were important with regard to obtaining forage resources. It was concluded that the deer brown brocket is a species of deer that requires a relatively small area to meet your requirements and has the chains and capons of forest as a habitat of great importance as regards the allocation of its area of use.

Efeito da época de transplante do almeirão no consórcio com a couve /

Carlos, Tancredo José January 2019 (has links)
Orientador: Cecílio Filho Arthur Bernardes / Resumo: O sistema de consorciação é uma tecnologia muito utilizada na produção de hortaliças, e que influencia profundamente a produtividade das culturas, além de gerar inúmeras vantagens fitotécnicas quando manejado adequadamente; tornando-se necessários maiores estudos sobre época de estabelecimento dos consórcios, uma vez que esta afeta o período de convivência entre as espécies com reflexo nas produtividades. O objetivo foi avaliar e quantificar, por meio de índices agronômicos e ecológicos, a interação entre couve e almeirão em cultivos consorciados, distintos quanto à época de transplante do almeirão em relação à couve. Foi realizado um experimento em campo, em Jaboticabal, SP, Brasil, no período de maio a novembro de 2018. O delineamento utilizado foi de blocos casualizados, com 9 tratamentos, em esquema fatorial 2 x 4 + 1, com quatro repetições. Os fatores avaliados foram sistema de cultivo (consórcio e monocultura) e épocas de transplante do almeirão (0, 14, 28 e 42 dias após o transplante (DAT) em relação à couve, e a monocultura da couve. A produtividade da couve ‘HS-20’ em consórcio com almeirão ‘Folha Larga’ aumentou com o atraso de transplante do almeirão. A produtividade total e por colheita do almeirão não foi influenciada pela época de transplante. Consórcio de couve e almeirão proporciona maior eficiência no uso da área que suas monoculturas, e atingiu o valor máximo quanto o transplante ocorreu aos 42 dias após o transplante da couve. Os índices ecológicos atestam ...

The experimental design was a randomized complete block with 9 treatments, in a 2 x 4 + 1 factorial scheme, with four replications. The factors evaluated were the cultivation system (intercropping and monoculture) and chicory transplant times (0, 14, 28 and 42 days after transplanting (DAT) relative to collard green and one monoculture of collard green. The yield of collard green 'HS-20’ in intercropping with chicory 'Folha Larga' increased with the delayed transplantation time of the chicory. The total yield and yield per harvest of the chicory was not influenced by the time of transplantation. The collard green and chicory in intercropping provides greater efficiency in the use of the area than their monocultures, and reached the maximum value whe...

Beaver Movements On Managed Land In The Southeastern United States

McClintic, Lance Forest 11 May 2013 (has links)
I studied movement characteristics and vegetative resources effects on home range size of beavers at Redstone Arsenal (RSA) in north central Alabama, USA. Beavers were captured and radio tagged from 11 wetlands during winter and spring of 2011. I monitored movements of radio-tagged beavers using radio telemetry from May 2011–April 2012. Beavers moved faster, presumably more favorable to central place foraging, in wetland as they proceeded farther away from the central place, but did not in upland. Additionally, distributions of hourly distances from lodges were bimodal. Home range, core areas, and distance from lodge did not differ between age classes. Home range sizes increased with increasing habitat productivity and resource dispersion, whereas home ranges decreased with temporal variation in resources throughout the year. Quantity and spatial distribution of resources and patterns of foraging behavior influence movements and home ranges of central place foragers.

Property regulation in South Africa : paving the way for regulation in Lesotho / Mpho Tsepiso Tlale

Tlale, Mpho Tsepiso January 2014 (has links)
Rapid growth of cities has become a trend in most countries, this is caused by urbanisation wherein people move from the rural areas to the urban areas in search of employment. It goes without saying that such population needs housing. However, it is unusual to find land for housing in an already crowded place. Therefore, to curb this shortage in housing, countries like South Africa have resorted to adoption of fragmented property holding in and around the cities. Thus, in an attempt to curtail housing shortages in the urban area as well as land shortage, communal property schemes were adopted together with their governing legislation namely, Sectional Titles Act 95 of 1986, Share Blocks Act 59 of 1980 and Property Time-sharing Control Act 75 of 1983 to name a few. Likewise, Maseru, the capital city of Lesotho is also experiencing rapid growth in population. Hence, with the introduction of Lesotho’s Sectional Titles Bill 2013 came a ray of hope that the land and housing shortage in Maseru would be addressed. With this in mind, this suggested that the Government of Lesotho together with all concerned stakeholders thought it necessary to address this problem through the 2013 Bill which, for the most part follows the South African Sectional Titles Act of 1986. It is for this reason that this study was embarked on to show other forms of property holding akin to sectional titles as well as their regulation, which can all be used to eliminate housing shortages in Lesotho. / LLM (Estate Law), North-West University, Potchefstroom Campus, 2015
