Exploring the relevance of a landscape ecological paradigm for sustainable landscapes and livelihoods: A case-application from the Northern Territory Australia     

Diane M. Pearson  Julian T. Gorman 《Landscape Ecology》2010,25(8):1169-1183

Global change is exacerbating the need for more effective mechanisms and approaches for working towards economic, social/cultural and environmental sustainability. It is now well recognised that science for sustainability will require integrated problem-focussed research that is by nature trans-disciplinary. Resolutions to both global and regional scale issues must involve participation of a diverse number of stakeholders. One region that would benefit greatly from such an integrated approach is the Northern Territory of Australia. This area is home to some of the most pristine savanna landscapes in the world and it is also occupied by one of the oldest living human cultures which are still in existence today. However, in recent years there has been increasing pressure to develop this region. The Northern Territory is also facing problems associated with having a growing Aboriginal population with deepening health and social problems. So as well as needing to facilitate adaptation in response to global change and development for economic prosperity of the region, there is an obligation to alter management practices to reduce social disadvantage. In light of this, it will be important that future landscapes are multifunctional and designed to ensure the preservation of biological and cultural diversity, as well as having provision for the livelihoods of the people that live within them. This article recommends the adoption of a landscape ecological approach for strategic development and sustainable planning, which captures and incorporates the values and identities of the different stakeholders, as well as engaging them in a continuous, adaptive process of planning and management, and in doing so discusses the importance of human ecological holism as part of the conceptual framework for landscape ecology.  相似文献

The effects of dredging operations on the benthic community of a chalk stream     

R.G. Pearson  N.V. Jones 《Biological conservation》1975,8(4):273-278

Sampling of the benthic fauna showed that dredging operations produced relatively short-term effects on invertebrate population levels. The behaviour of the animals was immediately affected, the differences between species were noted and the implications of dredging at different times of year are discussed.  相似文献   

THE GRASSLANDS OF EAST ANGLIA     

G. Pearson  Hughes 《Grass and Forage Science》1963,18(3):243-246

Because in the past the main emphasis was placed on arable farming, grassland husbandry has played a minor role in East Anglia. Now the increased efficiency exercised in the arable farming of the area is being applied to the grasslands. The main trends are discussed.  相似文献   

Feline spongiform encephalopathy: fibril and PrP studies.   总被引：1，自引：0，他引：1

The brains from 18 cats were examined for the presence of the fibrils and modified PrP protein which are molecular diagnostic markers for scrapie-like diseases. Thirteen cats were referred with clinical neurological signs potentially indicative of feline spongiform encephalopathy (FSE). Of these, five had histopathological changes of FSE, five had other lesions of the central nervous system, and in three the brain was normal. The remaining five cats had no clinical neurological signs and were selected as controls. Fibrils and modified PrP protein were found in the brains of the five cats with FSE and in one of the cats with neurological signs but no histopathological changes in the central nervous system. Fibrils were present in the absence of modified PrP in the brains of two cats, one with neurological signs and a histologically confirmed meningioma, and one with no neurological signs and a histologically normal brain.  相似文献   

A longitudinal study of veterinary students and recent graduates: 3. Perceptions of veterinary education   总被引：1，自引：1，他引：0  

TJ HEATH  A. LANYON  M. LYNCH-BLOSSE 《Australian veterinary journal》1996,74(4):301-304

Objective To examine the attitudes and opinions on veterinary education at the beginning and end of the veterinary course, and after graduation.
Design Longitudinal study.
Population Students – 154 in all – who began studying veterinary science at The University of Queensland in 1985 and 1986.
Procedure Questionnaires were completed in the first and fifth year of the course and in the second year after graduation. The data were analysed using the SAS System for Windows.
Results When they entered the course, the students were looking forward more to learning about animals than about basic sciences. At fifth year and after graduation most believed that more emphasis should have been placed on all facets of their education except the basic sciences. It may be difficult to increase this emphasis without placing undue pressure on the students, although more than half of the fifth year students and graduates agreed that there is much in the curriculum that is not needed by a practising veterinarian. Only one-third or less agreed that veterinarians are well equipped to practise veterinary science immediately they graduate. There was no relationship between the level of agreement with this statement, and the academic grades obtained.
Conclusions A majority of veterinary graduates do not believe that they are well equipped to practice immediately they graduate. They believe that more emphasis should have been placed on most facets of their education, but, conversely, that there is much in the curriculum that is not needed by a practising veterinarian.  相似文献

Comparison of Newcastle disease viruses isolated from cormorants in Canada and the USA in 1975, 1990 and 1992.   总被引：2，自引：0，他引：2       下载免费PDF全文

Seventeen Newcastle disease virus (NDV) isolates obtained from cormorants, turkeys, a pelican, and a gull in Canada and the USA collected in 1975, 1990 and 1992 were analyzed for relatedness by monoclonal antibody profiling. In addition, nucleotide sequence analysis was performed in two areas of the fusion (F) gene for 5 of the isolates. No difference in the antigenicity of these 17 viruses, as determined by monoclonal antibody binding patterns, was seen. The amino acid sequences obtained via nucleotide sequencing at the cleavage site of the F protein showed that all the isolates tested had two pairs of basic amino acids immediately upstream of the cleavage site, and a phenylalanine residue at the N-terminus of the F1 protein, which is consistent with velogenic NDV. The deduced amino acid sequence obtained at the cleavage site of the F protein from 6 of the isolates was virtually identical regardless of the species, year of isolation, or location. However, the 1975 cormorant isolate showed marked differences from the 1990-1992 isolates in the nucleotide and deduced amino acid sequence of the F gene signal region. These data indicate that the 1990 and 1992 outbreaks were caused by the same epizootic virus and further suggest that the population of NDV in these wild birds may be very stable. The belief that the velogenic NDV circulating in cormorants in 1992 was transmitted into the free-ranging turkey flocks located near the cormorants in North Dakota is supported by the present study in which no distinction could be made between the viruses isolated from turkeys or wild birds.  相似文献   

Clinical biochemical values of llamas: reference values     

E D Lassen  E G Pearson  P Long  W B Schmotzer  A J Kaneps  T W Riebold 《American journal of veterinary research》1986,47(10):2278-2280

Fifteen clinical biochemical measurements were done on serum from 64 clinically healthy adult llamas (26 males and 38 females). Values for several of these tests were different from those reported for llamas and from reference values for other domesticated ruminants. Comparison of values between males and females revealed significant differences for several tests. Clinical biochemical values reported in the present study can serve as reference values for adult llamas.  相似文献
