“…The predictable seasonal decline in patch density due to leaf drop as the dry season progresses and increase with leaf flush following commencement of rains allowed per cent patch retention to be calculated for each unburnt landscape unit by dividing the sum of daily patch density estimates by the maximum possible patch density over the annual cycle. The relationship between per cent patch retention, soil texture and woody canopy volume was then explored using the multiple non-linear regression routine of Labfit ( Silva & Silva, 2011 ). Labfit searches a library of 280 functions and outputs the one that best fits the data.…”

Determinants of seasonal changes in availability of food patches for elephants (Loxodonta africana) in a semi-arid African savanna

Loss of biodiversity caused by impact of elephants (Loxodonta africana) on African woodlands may require a management response, but any action should be based on an understanding of why elephants choose to utilise trees destructively. Comprehension of elephant feeding behaviour requires consideration of the relative value of the plant groups they may potentially consume. Profitability of available food is partly determined by the time to locate a food patch and, therefore, as a foundation for understanding the influence of food availability on diet selection, key controls on the density of grass, forb, and browse patches were investigated across space and time in a semi-arid African savanna. Density of food patches changed seasonally because plant life-forms required different volumes of soil water to produce green forage; and woody plants and forbs responded to long-term changes in soil moisture, while grasses responded to short-term moisture pulses. Soil texture, structure of woody vegetation and fire added further complexity by altering the soil water thresholds required for production of green forage. Interpolating between regularly-timed, ground-based measurements of food density by using modelled soil water as the predictor in regression equations may be a feasible method of quantifying food available to elephants in complex savanna environments.

“…The Z-statistic, with a value of 1.96, was used because the sample size was greater than 30. Labfit software ( Silva & Silva, 2011 ) was used to determine the function that best fit the relationship between mean handling time and the frequency of observations for each forage type.…”

As a foundation for understanding the diet of African savanna elephants (Loxodonta africana), adult bulls and cows were observed over an annual cycle to determine whether harvesting (Pt), chewing (Ct) and handling times (Ht) differed across food types and harvesting methods (handling time is defined as the time to harvest, chew and swallow a trunkload of food). Bulls and cows were observed 105 and 26 times, respectively (94 and 26 individuals), with a total of 64 h of feeding recorded across 32 vegetation types. Some food types took longer to harvest and chew than others, which may influence intake rate and affect choice of diet. The method used to gather a trunkload of food had a significant effect on harvesting time, with simple foraging actions being comparatively rapid and more difficult tasks taking longer. Handling time was constrained by chewing for bulls, except for the processing of roots from woody plants, which was limited by harvesting. Time to gather a trunkload had a greater influence on handling time for cows compared to bulls. Harvesting and handling times were longer for bulls than cows, with the sexes adopting foraging behaviors that best suited their energy requirements.

Este artigo apresenta os resultados de uma pesquisa bibliográfica que objetivou investigar as produções acadêmicas de dissertações e teses defendidas nos programas de pós-graduação stricto sensu no Brasil relacionadas ao software GeoGebra para os processos formativos dos professores de Matemática. Desta maneira, a questão norteadora que direcionou esta investigação foi: O que revelam as pesquisas acadêmicas (dissertações e teses) desenvolvidas no Brasil envolvendo o software GeoGebra para processos formativos dos professores de Matemática? Visando delinear compreensões a respeito do objetivo da pesquisa, utilizamos a pesquisa qualitativa, na modalidade de Estado do Conhecimento. Os dados da pesquisa foram coletados nas seguintes bases de dados: i) Biblioteca Digital de Teses e Dissertações (BDTD); ii) Catálogo de Teses e Dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). O corpus da pesquisa foi constituído por 140 pesquisas, sendo 124 dissertações de mestrado e 16 teses de doutorado envolvendo o software GeoGebra num contexto relacionado aos processos formativos dos professores de Matemática.
