The overall strategy is summarised in ADAS (1995), but information has been collated from individual monitoring reports to ensure that up to date details for each scheme are documented. 2.2 REVIEW TABLE This review is presented as Table 2.1. The table is divided into the following columns: A Endnote reference number This gives the number in the Endnote database from which the information in the row has been collated. B Scheme This column gives the scheme for which the report was written and in which the survey was carried out. C Monitoring Organisation This column gives the organisation(s) that carried out the project from which the information was gathered. D Habitat This column lists the habitats that were surveyed. E-F Sampling Strategy This column describes the sampling strategy and is split into two separate fields. The first field describes the sample size and distribution and the second field describes the sampling strategy at each site visited. G Population of which sample is representative This column indicates the population i.e. scheme or part of scheme that the sample represents. Parentheses indicate that the sample was believed to be representative by the authors, but was in fact subjectively chosen. H Field Method This column describes the method used in the survey. Some methods were generic in their application, having been used in several schemes or several habitats. They have been published and are included in the Endnote database that accompanies this report. The generic methods were:

Research paper thumbnail of Habitat invasions by alien plants: a quantitative comparison among Mediterranean, subcontinental and oceanic regions of Europe

Although invasions by alien plants are major threats to the biodiversity of natural habitats, individual habitats vary considerably in their susceptibility to invasion. Therefore the risk assessment procedures, which are used increasingly by environmental managers to inform effective planning of invasive plant control, require reliable quantitative information on the extent to which different habitats are susceptible to invasion. It is also important to know whether the levels of invasion in different habitats are locally specific or consistent among regions with contrasting climate, flora and history of human impact. 2. We compiled a database of 52 480 vegetation plots from three regions of Europe: Catalonia (Mediterranean-submediterranean region), Czech Republic (subcontinental) and Great Britain (oceanic). We classified plant species into neophytes, archaeophytes and natives, and calculated the proportion of each group in 33 habitats described by the European Nature Information System (EUNIS) classification. 3. Of 545 alien species found in the plots, only eight occurred in all three regions. Despite this large difference in species composition, patterns of habitat invasions were highly consistent between regions. None or few aliens were found in environmentally extreme and nutrient-poor habitats, e.g. mires, heathlands and high-mountain grasslands. Many aliens were found in frequently disturbed habitats with fluctuating nutrient availability, e.g. in man-made habitats. Neophytes were also often found in coastal, littoral and riverine habitats. 4. Neophytes were found commonly in habitats also occupied by archaeophytes. Thus, the number of archaeophytes can be considered as a good predictor of the neophyte invasion risk. However, neophytes had stronger affinity to wet habitats and disturbed woody vegetation while archaeophytes tended to be more common in dry to mesic open habitats. 5. Synthesis and applications. The considerable interregional consistency of the habitat invasion patterns suggests that habitats can be used as a good predictor for the invasion risk assessment. This finding opens promising perspectives for the use of spatially explicit information on habitats, including scenarios of future land-use change, to identify the areas of highest risk of invasion.

Research paper thumbnail of Correlation between magnetic resonance T2 image signal intensity ratio and cell apoptosis in a rabbit spinal cord cervical myelopathy model

Previous studies have shown that spinal cord cell apoptosis due to spinal cord compression plays an important role in the pathology of myelopathy. Although changes in magnetic resonance imaging (MRI) T2 signal intensity ratio (SIR) are considered to be an indicator of CSM, little information is published supporting the correlation between changes in MRI signal and pathological changes. This study aims to testify the correlation between MRI T2 SIR changes and cell apoptosis using a CSM animal model. Forty-eight rabbits were randomly assigned to four groups: one control group and three experimental chronic compression groups, with each group containing 12 animals. Chronic compression of the cervical spinal cord was implemented in the experimental groups by implanting a screw in the C3 vertebra. The control group underwent sham surgery. Experimental groups were observed for 3, 6, or 9 months afte...
