Abstract:
Bibliography: leaves 227-244. This study is conceived to address various aspects of western myall (Acacia papyrocarpa Benth) recruitment, lifespan, distribution and the effects of major vertebrates on the species' ecology over the major part of its range in South Australia. A study of the population dynamics of the species is done to assess the adequacy of net recruitment. Population structure is examined across the woodlands. The new concept of "fossil paddocks" is adopted to investigate the historical impact of introduced herbivores on the landscape.

Abstract:
Litter decomposition is a key component in ecosystem C and nutrient cycling. Shrubland litter decomposition is not well understood, even though shrublands cover a significant proportion of earth surface. This project aims to investigate the decomposition of shrubland plant residue (Cistus monspeliensis L.). The first and second experimental chapters of this thesis present the data about root chemistry, C and N mineralisation from the decomposing roots. Root tissue chemistry varies significantly with age, younger roots consist of higher relative amounts of N, P, K, soluble compounds, conversely

Abstract:
The grassland bird-community has declined significantly in abundance and diversity in Illinois over the past century. Reclamation of surface coal-mines in southern Illinois has created ca. 50,000 ha of grassland habitat that offers surrogate habitat for grassland and shrubland birds. Much of the grassland habitat created by reclamation of mine lands has not been managed and has succeeded to shrubland habitat dominated by both native and non-native shrubs. The purposes of this research were to identify the bird community utilizing reclaimed surface-mines in southern Illinois, and to examine the

Dryland ecosystems provide a unique opportunity to study the effects of water limitation on ecosystem activity. The sensitivity of these systems to small inputs of moisture is well-documented, but the expression of water limitation in terms of carbon dioxide flux between the ecosystem and atmosphere remains unclear. Applying a simple conceptual approach to soil moisture dynamics, patterns in carbon flux become clear. Release of carbon dioxide via respiration is primarily driven by moisture in the shallow soil, and differences in respiration rates among plant functional types are only evident a

Abstract:
A number of technical approaches had to be employed within the planner, namely, 1) translating expected reward into a probability of goal satisfaction criterion, 2) monitoring belief states with a Rao-Blackwellized particle, and 3) employing Rao-Blackwellized particles in the McLUG probabilistic conformant planning graph heuristic. POND-Hindsight is an action selection mechanism that evaluates each possible action by generating a number of lookahead samples (up to a xed horizon) that greedily select actions based on their heuristic value and samples the actions' observation; the average goal s

Abstract:
For the Arid Shrublands of Western Australia (WA) knowledge is limited on what sheep eat and how nutritious their diets are. A study was undertaken on two stations near Yalgoo (28º18’S 116º38’E) in WA, from November 2005 to December 2007. Station 1 (28º39’S 116º18’E) used a flexible rotational grazing management system (RGS), moving 3000-4000 Merino sheep every 3 – 6 weeks through a choice of 20 paddocks. Station 2 (28º18’S 116º42’E) used a flexible continuous grazing management system where small mobs (500 sheep) stayed in paddocks all year, until shearing. Two paddocks on Station 2 were chos

Abstract:
Shifting climate patterns are a cause for concern for natural ecosystems globally. Of particular concern is the effect of climate change on fire-prone, Mediterranean-type shrublands globally because of the heightened sensitivity of post-fire vegetation to environmental conditions. In this thesis, I focused on investigating the relationships between rainfall seasonality patterns and post-fire vegetation processes in neighbouring Fynbos and Renosterveld shrubland communities within the mega-diverse Cape Floristic Region of South Africa. I investigated vegetation sensitivity to moisture availabil

Abstract:
In the period from May 2010 to August 2011, spider fauna of semi natural olive groves and associated shrub-lands were sampled in Mugla Province, Milas District, Kiyikislacik Village at the Western Mediterranean coast of Turkey. Semiquantitative sampling protocols were performed by use of pitfall traps, sweep nets, by active collecting, by sifting of tree litter and beating branches of shrubs. A total of 9967 spider specimens were obtained, from these, 3034 adult specimens were determined up to the lowest taxonomic category, and a detailed checklist is produced for the study area, composed of a

Abstract:
No Sul do Brasil ocorrem mosaicos naturais de vegetação campestre e florestal, sob um clima que é favorável às formações florestais. O processo de expansão florestal tem sido observado principalmente sobre áreas de campo excluído de perturbações de fogo e pastejo. Estudos sobre padrões de vegetação lenhosa associados a variáveis ambientais locais em áreas de campo sujeitas à expansão florestal constituem uma importante ferramenta para avaliação da dinâmica da vegetação considerando mudanças ambientais ou de regime de perturbação. No intuito de inferir sobre os processos relacionados à expansão

The purpose of this thesis was to classify and describe low-elevation grassland and shrubland vegetation, mid-elevation woodland and forested vegetation, and high elevation alpine vegetation associations of the Beartooth Mountains study area and to compare newly derived associations with existing habitat type and community type classifications of ecologically relevant environments in Montana, Wyoming and Idaho. Five grassland/shrubland associations, twelve woodland/forested associations and thirteen alpine associations were classified and described for the Beartooth Mountains study area. Prior

Abstract:
The objective of the study was to assess the farmers’ knowledge and perceptions of P. incana invasion and impacts on rangeland, livestock production and livelihood in four communal grazing areas. Twenty households per village that own livestock were randomly selected to conduct an interview using an open and closed ended questionnaire. In each household, an old and knowledgeable respondent about P. incana invasion was used as a selection criterion. For scientific assessment of range condition, the experiment was conducted in a 270 m x 100 m trial plots that were established in 2014. The area w
