Sandy coastlines are sensitive ecosystems where human activities can have considerable negative impacts. In particular, trampling
by beach visitors is a disturbance that affects dune vegetation both at the species and community level. In this study we
assess the effects of the limitation of human trampling on dune vegetation in a coastal protected area of Central Italy. We
compare plant species diversity in two recently fenced sectors with that of an unfenced area (and therefore subject to human
trampling) using rarefaction curves and a diversity/dominance approach during a two year study period. Our results indicate
that limiting human trampling seems to be a key factor in driving changes in the plant diversity of dune systems. In 2007
the regression lines of species abundance as a function of rank showed steep slopes and high Y-intercept values in all sectors, indicating a comparable level of stress and dominance across the entire study site. On the
contrary, in 2009 the regression lines of the two fenced sectors clearly diverge from that of the open sector, showing less
steep slopes. This change in the slopes of the tendency lines, evidenced by the diversity/dominance diagrams and related to
an increase in species diversity, suggests the recovery of plant communities in the two fences between 2007 and 2009. In general,
plant communities subject to trampling tended to be poorer in species and less structured, since only dominant and tolerant
plant species persisted. Furthermore, limiting trampling appears to have produced positive changes in the dune vegetation
assemblage after a period of only two years. These results are encouraging for the management of coastal dune systems. They
highlight how a simple and cost-effective management strategy, based on passive recovery conservation measures (i.e., fence
building), can be a quick (1–2 years) and effective method for improving and safeguarding the diversity of dune plant communities. 相似文献

This paper assesses the private and social profitability of current strategies for managing processionary moth (Thaumetopoea pityocampa) in Portuguese pine forests, looking at economic and environmental costs and benefits. Costs include the expenses for forest treatment and the social costs of threats to human health (dermatitis amongst others); benefits are assessed in terms of both revenue and social benefits such as carbon fixation and recreation. The evaluation was done using Cost Benefit Analysis (CBA) as an analytical framework. While this tool is currently applied to forest and environmental assessment and specific applications to pest management strategies are to be found in agricultural economics, rather few attempts have been made in the field of forest pest management. In order to assess and compare with--without options, a case-study was analysed for the Setúbal Peninsula, south of Lisbon, an area where extensive stands of maritime pine (Pinus pinaster) grow. The exercise has shown that CBA can be a valuable tool for assessing the economic and social profitability of pest management. The results demonstrate that the loss of revenues in the no-management option is not sufficient to make pest management profitable for private forest owners in the short-term. Conversely, a social profit is gained as pest management minimizes health risks for humans and avoids possible recreational losses. 相似文献

Scale-up of anodic oxidation system is critical to the practical application of electrochemical treatment in bio-refractory organic wastewater treatment. In this study, the scale-up of electrochemical flow system was investigated by treating petrochemical wastewater using platinized titanium (Ti/Pt) and boron-doped diamond (BDD) anodes. It was demonstrated that flow cell was successfully scaled-up because when it was compared with batch mode (Rocha et al. 2012b), higher performances on organic matter removal were achieved. Under the suitable operating conditions and better anode material, the chemical oxygen demand (COD) of petrochemical wastewater was reduced from 2,746 to 200 mg L?1 within 5 h with an energy consumption of only 56.2 kWh m?3 in the scaled-up BDD anode system. These results demonstrate that anode flow system is very promising in practical bio-refractory organic wastewater treatment. 相似文献

Osteoarthritis (OA) is a chronic degenerative condition involving the joints caused by metabolic changes in chondrocytes metabolism.
Treatment with magnetic fields (EMFs) produces benefits to patients affected by this pathology. The present research has the
aim to investigate, by a proteomic approach, the effect of magnetic fields on cultured chondrocytes, because EMFs interferes
greatly with OA chondrocytes metabolism. Human osteoarthritic chondrocytes were obtained from the femur head of osteoarthritis
adult patients and were cultured under standard conditions and exposed for precise times both to extremely low-frequency (ELF;
100-Hz) electromagnetic fields and to the Therapeutic Application of Musically Modulated Electromagnetic Fields (TAMMEF),
which are characterized by variable frequencies, intensities, and wave shapes. We tested the effects of the different exposure
by 2-DE analysis and demonstrated that chondrocytes metabolism was highly influenced by the treatment with EMFs; in fact many
proteins change their expression after the stimulation, but differently, depending on whether we use ELF or TAMMEF system. 相似文献

In our paper we studied the effects of exposure to ELF (extremely low frequency) or musically generated TAMMEF (therapeutic
application of musically modulated electromagnetic fields) electromagnetic fields on the tumor necrosis factor alpha (TNF-α)
release induced by a lipopolysaccharide (LPS) from cultured human lymphomonocytes of peripheral blood. Lymphomonocytes, isolated
from blood donors buffy-coat, were prepared using standard techniques in cell culture flasks, kept in CO2 incubator, with controlled temperature and humidity for 5 days. Flasks were subjected to an ELF electromagnetic field (100 Hz
sinusoidal) or to TAMMEF electromagnetic fields (with intensity, frequency, and wave shape randomly modified in time, so that
all possible codes can occur during a single application). The TNF-α release was determined by ELISA test every 24 h for 92 h
and the results were evaluated by a non-parametric test. LPS induces a stronger TNF-α release in cultures that were subjected
to ELF when compared with cultures subjected to TAMMEF, at each time period of the experimental protocol. These results seem
to indicate that TAMMEF is able to induce a complex modulation of LPS-induced TNF-α release, a cytokine with pro inflammatory
property whose release during chronic or neoplastic inflammatory diseases has strong negative effects on several organ systems. 相似文献

In Cupressus sempervirens the association between seed insects and tree pathogens has resulted in optimal exploitation of the cones. A fungus-infected
cone can be inhabited by the nymphs of a true seed bug (Orsillus maculatus), the adults of which may carry a heavy spore load at emergence. Cones are infected when eggs are laid within the cone, most
frequently via the emergence holes of a seed wasp (Megastigmus wachtli). This symbiotic association evolved with the nonaggressive fungus Pestalotiopsis funerea within the natural range of the cypress. When the aggressive cypress canker disease (Seiridium cardinale) was introduced into Europe, it was transmitted by O. maculatus to cones usually colonized by Pestalotiopsis funerea, with disastrous consequences for the regeneration and survival of C. sempervirens in the entire Mediterranean area.
