Effectiveness of conservation easements for reducing development and maintaining biodiversity in sagebrush ecosystems     

Amy Pocewicz  Joseph M. Kiesecker  George P. Jones  Holly E. Copeland  Jody Daline  Brian A. Mealor 《Biological conservation》2011,(1):567-574

Conservation easements are the primary tool used globally by land trusts and governmental agencies to achieve conservation goals on private lands, but empirical evaluations of their effectiveness are lacking. Here we compared biodiversity in sagebrush ecosystems and recent rates of change in road and structure densities on properties with and without easements held by The Nature Conservancy in Wyoming, USA. To determine whether any differences between properties with and without easements were better explained by development pressure or by management practices, properties were stratified by low versus high residential development pressure and property managers were surveyed. In areas with high development pressure, easement properties had fewer structures and tended to have fewer, smaller roads than properties without easements. In the high-pressure areas, properties with easements also had greater use by some wildlife species than properties without easements. Regardless of easement presence, there was higher cover of exotic plant species and fewer mammal burrows in high than low-pressure areas. There were no significant differences in land management practices between properties with and without easements, but managers of properties with easements tended to seek management support more often than other managers. This may present an opportunity to provide support for specific management activities on easements to ensure that they continue to meet intended goals. Given the importance of easements as an alternative to nature reserves and the significant investment being made to acquire additional easements, it is essential to continue to evaluate whether easements are an effective tool in other locations.  相似文献   

Growth Environment Influences Grain Protein Composition and Dough Functional Properties in Three Australian Wheat Cultivars     

Noor Hasniza M. Z.  Meredith A. Wilkes  Surjani Uthayakumaran  Les Copeland 《Cereal Chemistry》2014,91(2):169-175

The objectives of this study were to assess how functional properties of proteins in whole meal wheat (Triticum aestivum L.) flour vary across different growth environments. Grain from three commercial Australian Hard milling wheat cultivars was analyzed from four growth locations in 2008 and from two of the corresponding cultivars and locations in 2009. The protein content of the grain, soluble and insoluble extractable protein fractions, swelling index of glutenin (SIG), glutenin‐to‐gliadin ratio (Glu:Gli), percent unextractable polymeric protein (%UPP), and dough properties including force at maximum resistance (Rmax) and extensibility were measured. Based on analysis of variance of aggregated data for the cultivars, growth locations, and seasons, growth environment factors made significant contributions to variability in the total grain protein, Glu:Gli ratio, %UPP, SIG, Rmax, and extensibility of the wheat flour. Variability of protein content of the soluble and insoluble extractable protein fractions was mostly owing to genotype.  相似文献

A micromethod for measuring swine fever antibody by neutralisation and immunofluorescence     

J S Loi  G H Lim  K T Chu  M K NG 《Research in veterinary science》1986,40(3):408-410

A micromethod employing the neutralisation and direct immunofluorescence technique for the detection of antibodies against swine fever in pig serum samples is described. The micromethod is simple and reproducible when compared with the macromethod. A total of 80 blood samples were randomly collected for comparison. The results are promising and reveal a 100 per cent correlation with the macrotechnique.  相似文献   

Dairy cow preference for a soft track surface     

NG Gregory  OD Taylor 《New Zealand veterinary journal》2013,61(2)

Abstract

Extract

As dairy herds get larger cows have to walk further, and foot care becomes more important. Lameness from bruising of the soles of the feet is a particular hazard (Tranter and Morris 1991 Tranter, W P and Morris, RS. 1991. A case study of lameness in three dairy herds. New Zealand Veterinary Journal, 39: 88–96. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar], especially on hard tracks with loose angular stones or grit (Clackson and Ward 1991 Clackson, DA and Ward, WR. 1991. Farm tracks, stockman's herding and lameness in dairy cattle. Veterinary Record, 129: 511–512.  [Google Scholar]. One way of reducing this problem might be to provide an overlay of woodchips on top of the normal hard track. This would provide a softer grit-free surface, which could be more comfortable for the cows.  相似文献

Amylolysis of wheat starches. I. Digestion kinetics of starches with varying functional properties     

Jaroslav Blazek  Les Copeland 《Journal of Cereal Science》2010

The susceptibility of wheat (Triticum aestivum L.) starches to hydrolysis by pancreatic α-amylase in vitro was investigated using a series of 35 starches with slightly enriched amylose content within a narrow range (36–43%), but widely differing functional properties. After 2 h of incubation with α-amylase, native starch granules were digested to different extents, but there were no differences between any of the starches once they were gelatinized. Cooling the starch for 72 h at 4 °C after cooking reduced the susceptibility of all of the starches to enzymic digestion by a similar extent, whereas addition of monopalmitin decreased the digestibility of the starches that contained amylose, but did not affect the digestibility of waxy starches that were also included in the study. Amylopectin chain length distribution of partly digested starch granules displayed increased proportion of short and medium chains and decreased proportion of long chains in comparison to native granules. Separated large (A) and small (B) starch granules from three of the starches differed significantly in their susceptibility to in-vitro digestion. A predictive model of the susceptibility of starch in the different forms was developed from the physico-chemical and functional properties of the starches.  相似文献
