2 PSU (i.e. a little bit above 7 PSU, the undisturbed value of the upper layer salinity). Time series of the above-defined SB431542 datasheet constituents of down-channel momentum budget calculated for the central point of the mid cross-section of the channel using the POM simulation (Figure 5, top panel) show that within a period of 1–4 days the bottom friction force −u*2 is balanced by the sum of the pressure gradient force and the Coriolis force BCx + BTx + COx, while after 4 days the bottom friction force gradually disappears and eventually the negative value of BCx + BTx balances the positive value of COx. Formally

such a balance does not fit the ‘classical’ bulk down- channel momentum budget in a frictionally controlled gravity current when the pressure gradient force due to the down-channel tilt of the interface balances the bottom friction (assuming that the interfacial entrainment stress is negligible) INK 128 manufacturer while the pressure gradient force due to the cross-channel tilt of the interface is geostrophically balanced by the gravity flow velocity ( Wåhlin 2002). However, one may suggest that for the closed channel geometry

shown in Figure 3 the gravity current in the mid cross-section is skewed, so that the down- and cross-channel tilt of the interface may differ from that of the down- and cross-stream. Based on this suggestion, one may perform a standard transformation from the down-channel-oriented Cartesian co-ordinates xy to the downstream-oriented ones x′y′ using the constraint COx′ = 0, where x′ is the downstream axis, and formulate the downstream momentum budget instead of the down-channel one. Time series of the downstream constituents of the bulk momentum budget BCx′+BTx′BCx′+BTx′,

−u′*2 and the angle φ   between the x′y′   and xy   coordinate systems ( Figure 5, bottom panel) clearly show after an initial 1 day period the balance between the positive BCx′   + BTx′   and the negative −u′*2, so that the gravity current can be undoubtedly treated as frictionally controlled. Note that BCx′   + BTx′   and −u′*2 disappear simultaneously with time, while the absolute values of the baroclinic and barotropic downstream pressure gradient constituents, RAS p21 protein activator 1 BCx′ and BTx′, remain large (not shown). In any case, after 5 days the gravity current no longer exists (see Figure 5, the bottom panel). Note that the downstream angle is negative (–20° > φ > –2°) at t < 1 day (before the gravity current is formed), slowly increases from φ ≈ –2° to φ ≈ 5° within the period of 1 day < t < 4 days when there is a frictionally controlled gravity current, and increases faster to φ ≈ 17° at t = 5 days when the bottom stress vanishes. The mean values of the Froude number, the Ekman number and the Ekman depth, averaged over the period of 1–4 days, were estimated at Fr = 0.

3C). Despite that, we observed only a slight increase in IFN-γ secretion in the cultures of spleen cells from mice fed 3% yacon FOS in comparison with those from the other groups. There were no significant differences in IL-4 secretion in those cultures ( Fig. 3D, E). To evaluate the effects

of yacon consumption on the macrophage functions, the levels of nitrite, IL-1β, TNF-α, and IL-10 were measured in culture supernatants of thioglycollate-elicited mouse peritoneal macrophages stimulated in vitro with LPS and IFN-γ. The nitrite levels were similar in the supernatants of macrophages obtained from mice of the different dietary groups ( Fig. 4A). Similarly, no significant differences were observed in the levels of TNF-α Selleck BKM120 and IL-10. However, MI-773 in vivo a pronounced reduction in IL-1β secretion was observed in the cell cultures derived from mice fed with rations containing FOS of any source in comparison with the control group. Prebiotic effects have been defined as “the selective stimulation of growth and/or activity(ies)

of one or a limited number of microbial genus (era)/species in the gut microbiota that confer(s) health benefits to the host” [21]. The presence of healthy intestinal microbiota promotes a state of immune tolerance, which prevents the immune response against commensal organisms and dietary proteins avoiding food allergies and bowel disorders such as irritable bowel syndrome. Moreover, the consumption of prebiotics improves stool quality as measured by pH, short-chain fatty Bacterial neuraminidase acid, frequency, and consistency; reduces the risk of infections and gastroenteritis; and increases Ca absorption, bone calcium accretion, and bone mineral density [9] and [22]. As observed in this study, yacon root flour contains reduced quantities of glucose and fructose and high levels of FOS, which is found in higher

proportion in the yacon than in other sources of prebiotic substances such as chicory or Jerusalem artichokes (22.9/100 g and 13.5/100 g, respectively) [23] and [24]. Variations in the levels of FOS in yacon may depend on factors such as localization, farming, the growing season, and harvest time and temperature in the postharvest [25]. The commercial FOS consists of short-chain FOSs (GF2, nystose, and GF4), and it is a natural prebiotic fiber produced from sugar cane. Recent study conducted in adult women (31–49 years) with mild obesity and dyslipidemia has shown positive effects resulting from yacon consumption [26]. In these patients, the consumption of 0.14 or 0.29 g FOS/kg body weight for 120 days resulted in reduction of body weight, body mass index, and serum insulin, as well as an increase of the frequency of defecation and satiety. In a study conducted in rats, the consumption of yacon flour containing 5% or 7% FOS resulted in an increase of calcium absorption that seems to be correlated with increasing in depth and number of intestinal crypts [25].

Missing data were replaced

by a negative answer for the latter analyses, A chi-square test was used when comparing groups while McNemar’s test was used to examine changes within groups from baseline to post-intervention for categorical variables. Independent t-tests were used to compare Akt tumor groups while paired t-tests were used to examine changes within groups from baseline to post-intervention for continuous variables. The statistical significance for all analyses was set at p < 0.05 (two-sided). SPSS Version 20.0 (SPSS Inc. Chicago, IL, USA) was used for all analyses. Participants were recruited from 12 pharmacies. The response rate to the mailed invitation to enroll in the study among eligible participants identified by their pharmacists was 15%. A total of 144 participants who received the educational intervention

are included in this analysis. Table 1 shows demographic, general health status and prescription-related characteristics of the entire cohort at baseline. Participants were mostly female (73%), had an average age of 75, and the majority (83%) had no formal college or university education. Half of all participants Selleckchem Fulvestrant had previously attempted benzodiazepine discontinuation, 25% of whom had successfully weaned off the drug at some point. Post-intervention, 45.1% (n = 65) of participants reported increased perceived risk from consumption of benzodiazepines. There were no statistical differences in baseline characteristics between individuals perceiving an increased risk (RISK) and those with no perceptions of increased

risk (NO RISK), except for a trend showing a shorter duration of benzodiazepine use among the RISK group (p = 0.08) ( Table 1). Knowledge about benzodiazepines was similar between groups at baseline. Changes in knowledge both within and between risk groups are described in Table 2. Eighty percent (52/65) of participants in the RISK group changed an answer from incorrect to correct on at least one knowledge question from pre- to post-intervention compared to only 41% (33/79) in the NO RISK group. The pheromone RISK group demonstrated a significantly higher proportion of correct answers post-intervention on the safety, side effects and alternatives questions compared to the NO RISK group (p < 0.001). Only participants in the RISK group who had the potential for knowledge acquisition showed a statistically significant increase on the overall knowledge score (mean change score 1.77 SD (1.3)). The change in overall score was significantly greater among these individuals in the RISK group post-intervention compared to the NO RISK group (mean change score 0.91 95% CI (0.5, 1.3)). Beliefs about benzodiazepines were similar between groups at baseline. Table 3a and Table 3b show changes in beliefs about the necessity, perceived negative consequences, and risk-benefit ratio of benzodiazepine use.

Compounding the decrease in large predatory fish abundance, another side-effect of trophic cascades is the prevention of successful recruitment of high level species. Fish body size is generally correlated with trophic level. As such, piscivorous fishes tend to be zooplanktivorous as larvae [1] and [4]. This lower trophic level of young fish would place them in direct competition with the now abundant small pelagic species. In fact, these larval fish may also become the prey of the lower trophic level pelagic fishes. Trophic cascades have been documented in ecosystems around the world, due to the prevalent decline in biomass of large

predatory fishes. In a 2005 study, Myers and Worm examined the exploitation and ecological extinction of predatory fishes worldwide. NVP-BGJ398 order Their study documented an average decline in predatory fish abundance to 10% of its pre-exploitation level, with sensitive species such as sharks closer to 1% of pre-exploitation levels. This decline resulted in the ecological extinction of most species examined. Indeed, the authors commented on the prevalence of documented trophic cascades created due to predatory fish decline associated with overexploitation.

One documented trophic cascade in the Bohai Sea attributed to overexploitation of top predators resulted in a 300% increase in phytoplankton [32]. One researcher went so far to say that “fisheries extirpate trophic Bcl-2 inhibitor levels” [33]. Under the scenario of fishing down, this certainly appears true. A primary characteristic of fishing through the food web is an initial high-trophic level fishery followed by the sequential addition of lower-level stocks into the fishery. This strategy would suggest that fishing pressure of upper-level species did not result in the collapse of apex predators. Since this strategy would not necessarily result in an ecological extinction of high-trophic level species, a trophic cascade would be less likely, although

still a significant concern. Instead, the addition of multiple trophic levels to the fishery would result in a more comprehensive attack on trophic interactions within the ecosystem. In addition Protein kinase N1 to risking ecological extinction of top predators and subsequent trophic cascades, fishing at multiple trophic levels could allow collapse of lower-trophic level species. In a 2011 study, Pinsky et al., caution that small pelagic fishes are highly catchable and are therefore very susceptible to overfishing. It is generally overlooked, however, as small pelagic species tend to be R-selected, having increased fecundity, decreased time to maturity, and low parental investment. Because of these life-history characteristics, scientists have generally assumed that these species will be able to sustain high fishing yields due to a shorter generation time. Pinsky et al.

longicornisKB five calculation runs were done for 5, 10, 12.5, 15 and 20°C at different food levels. The impact see more of temperature on growth rates was defined by the function

fte, which at lower temperatures (< 15°C) is described by Q10 and at higher ones by the parabolic threshold function ft2. The growth rate of T. longicornisKB increases rapidly with rising temperature in the 5–15°C range but less so with a food concentration from 25 mgC m−3 to excess. But the growth rates for the model stages were nearly equal at both 15°C and of 20°C according to the function fte. Figure 5 shows that the optimum temperature for the development of T. longicornis is slightly higher than 15°C. In the real environment during summer, in the 15–20°C temperature range, and probably with limited food availability, an increase in temperature reduces growth of almost all developmental stages. The growth rate of T. longicornisH at 12.5°C in the 25–200 mgC m−3 range of food concentration was also obtained here after data given by Harris and Paffenhöfer, 1976a and Harris and Paffenhöfer, 1976b. If we compare our results of g for T. longicornisKB at 12.5°C to the same stage groups as in their studies and assume that N1 does not grow, it appears that those authors selleck kinase inhibitor probably found values similar to (Temora) or higher than (Pseudocalanus) those found by Klein Breteler et al. (1982) at the same food concentration

and temperature (see pp. 205–206 in Klein Breteler et al. 1982). The values of g for T. longicornisH except the naupliar stages are higher than those for T. longicornisKB at 12.5°C, which were computed using the equation given by Hirst et al. (2005) and according to the Q10 coefficient. On the basis of the findings and analysis in this study, differences in g are found between the two species and are smaller if the correction by Hirst et al. (2005) is included. The growth rate of T. longicornisH is from 1.15

to 2.4 times higher than g for T. longicornisKB and depends on development stage and food concentration; for example, for early copepodids assuming Protein kinase N1 Food = 200 mgC m−3, g is equal to 0.43 day−1 and 0.374 day−1, and for Food = 25 mgC m−3, g is equal to 0.24 day−1 and 0.121 day−1 respectively. It is more probable that the difference between the results found by these authors is explained by the different algae used as food and other conditions of the experiments. The quality and quantity of food available to copepods is very important for their growth and development. In natural conditions copepod diets are selective and diverse. Selectivity by copepods may relate to the size of the prey (Atkinson 1995), its toxicity (Huntley et al. 1986) and nutritional quality (Houde & Roman 1987). Copepods often consume not just phytoplankton but heterotrophic flagellates and ciliates, detritus and other metazoans, and they can feed cannibalistically (Hirst & Bunker 2003).

CquiOR21 is one residue shorter than CquiOR10 and these proteins differ in two residues: Ala-345 followed by Ile-346 in CquiOR21 and Ile-345-Thr-Val-347 in CquiOR10 ( Hughes et al., 2010). The “skipped” threonine (Thr-346) residue could be an error of annotation given that Ile-346 in CquiOR21 (VectorBase) overlaps with an intron splice site, whereas

the other differences could be due to polymorphism, Docetaxel mouse including one possible SNP (Val-347 vs Ile-346). In summary, we assume that CquiOR121 and CquiOR21 in VectorBase are isoforms of CquiOR2 (GenBank, ADF42901) and CquiOR10 (ADF42902), respectively. They might be alleles from the same genes from different populations. Thus, we wish to reconcile www.selleckchem.com/products/AZD2281(Olaparib).html these discrepancies in the Culex OR nomenclature by renaming our previously identified CquiORs as CquiOR121 (=CquiOR2) and CquiOR21 (=CquiOR10). We have revised our previous phylogenetic analysis of mosquito ORs (Pelletier et al., 2010) in view of the annotation

of the Culex genome ( Arensburger et al., 2010), the update to Cx. quinquefasciatus gene sets (VectorBase), corrections of annotation mistakes ( Pitts et al., 2011) and identification of pseudogenes. With these corrections, our estimate of 158 ( Pelletier et al., 2010) and a later report of 180 putative OR genes ( Arensburger et al., 2010) are now updated to 130 putative OR genes in the Cx. quinquefasciatus genome, whereas Ae. aegypti has 99 putative OR genes and An. gambiae 76 ORs. Despite significant reduction, Culex has still the largest repertoire of ORs of all dipteran species examined to date, as was previously suggested ( Arensburger et al., 2010). The observed Culex/Aedes and Aedes/Culex specific expansions ( Pelletier et al., 2010) remain valid, as does the Anopheles specific expansion ( Fig. 2). In an attempt to identify

Culex ORs, we selected 6 putative ORs, five of which with no An. gambiae orthologs and two from these Culex–Aedes expansions, to clone and de-orphanize. Previously we Metformin supplier identified two CquiOR genes, CquiOR21 and CquiOR121 ( Fig. 1, bottom of the figure). We used the odorant response profiles of An. gambiae ORs ( Carey et al., 2010 and Wang et al., 2010) to lead us to orthologous ORs in the genome of Cx. quinquefasciatus. Here, we attempted a different approach, i.e., by selecting 6 ORs in the phylogenetic tree, 5 of them with no An. gambiae orthologs. Starting from the left of the tree ( Fig. 1), they are: CquiOR44 (=CPIJ802556), CquiOR87 (=CPIJ802589), CquiOR110 (=CPIJ802608), CquiOR1 (=CPIJ802517), CquiOR73 (=CPIJ802564), and CquiOR161 (=CPIJ802651). Attempts to clone CquiOR87 and CquiOR110 were unrewarding thus suggesting that these genes are not expressed in adult female antennae. We successfully cloned the other genes and their sequences have been deposited in GenBank (CquiOR1, KF032022; CquiOR44, KF032024; CquiOR73, KF032023; CquiOR161, KF032025).

The short-wave radiation flux penetrating the open-water surface is given by equation(22) Fsw=Fs1−αw, where αw is the surface-water albedo calculated from the Fresnel formulas ( Jerlov 1968): equation(23) αw=12tan2Θa−Θwtan2Θa+Θw+sin2Θa−Θwsin2Θa−Θw, where Θa and Θw are the angles between the z-axis and the rays in the atmosphere and water respectively. Further details concerning the heat fluxes and constants are given in Omstedt & Axell (2003). “
“The Strait of Istanbul has a two-layered flow system between the Black Sea and the Sea of Marmara. The lower layer carries the more saline water to the subhalocline part

of the Black Sea while the upper layer carries the less saline water to the Sea of Marmara. The upper p38 MAPK inhibitor layer (∼ 18 PSU) originates from the Black Sea, the lower layer (∼ 38 PSU) from the Sea of Marmara. Flow exchange is affected

mainly by the hydraulic conditions generated by the geometry of the strait. One specific water mass through the strait is the cold intermediate water (CIW) observed below the seasonal thermocline in the Black Sea during the summer months (Tolmazin, 1985 and Stanev, 1990). Part of CIW is found in the Strait of Istanbul and the Sea of Marmara. The warm and more saline lower layer, called Mediterranean water, flows to the Black Sea and extends as a salt wedge over the continental shelf and is controlled by a sill lying in the northern extension of the Bosphorus channel (Ünlüata et al.,

1990, Yüce, 1990, Yüce, 1996a, Yüce, selleckchem 1996b, Latif et al., 1991 and Di Iorio and Yüce, 1999). The Mediterranean water effluent mixes with CIW, and its temperature and salinity decrease in the shelf region of the Black Sea exit of the Strait of Istanbul (Özsoy et al., 1991, Özsoy et al., 2001, Oğuz and Rozman, 1991 and Gregg and Özsoy, 1999). The influence of this water can be seen in the intermediate layer in the Black Sea (Buesseler et al., 1991 and Özsoy et al., 1993). Tsimplis et al. (2004) analysed long term data and found a significant correlation between the salinity of the upper water of the Aegean Sea and the layer between 50 and 300 m in the Black Sea, indicating that the (-)-p-Bromotetramisole Oxalate latter layer is a product of the Mediterranean inflow. CIW is defined as water of temperature < 8 °C located between the seasonal and permanent halocline in the Black Sea. In the central basin of the Black Sea, it lies at depths of 50–150 m (Tolmazin, 1985 and Stanev, 1990). The main source of CIW is considered to be the cold north-western shelf waters during the winter months in the Black Sea (Tolmazin 1985). The other source of CIW is thought to be the centre of cyclonic eddies (Ovchinnikov & Popov 1987). Ivanov et al. (1997) claim that CIW is partly formed in coastal anticyclones. Its temperature and salinity characteristics provide evidence for its existence in different parts of the sea (Oğuz et al. 1998).

1B). Fig. 1C shows a representative record of the neuromuscular blockade produced by a venom concentration of 10 μg/ml. Incubation with

venom did not significantly alter the muscle contractures to exogenous GDC-0199 nmr ACh and KCl (responses to ACh were 119 ± 4, 113 ± 23, 120 ± 33, 119 ± 19, 147 ± 17, 118 ± 12 and those to KCl were 88 ± 3, 89 ± 2, 85 ± 11, 92 ± 7, 105 ± 2 and 98 ± 2 for 0.1, 0.3, 1, 3, 10 and 30 μg of venom/ml, respectively, expressed as a percentage of the control, considered as 100%; n = 4–9 each), indicating a lack of effect on postsynaptic nicotinic receptor function and muscle fiber integrity, respectively. However, venom (10 μg/ml) did cause a slight but significant increase in CK towards the end of the experiment when compared to control preparations

(CK activity, Dasatinib cost U/ml: 80 ± 15, 31 ± 8, 76 ± 4, 113 ± 22, 157 ± 24* and 206 ± 25* at 0 min, and 15, 30, 60, 90 and 120 min after venom, respectively; *p < 0.05 compared to 0 min; n = 6 each). In contrast to chick biventer cervicis preparations, in mouse phrenic nerve-diaphragm preparations the three venom concentrations tested (1, 10 and 30 μg/ml) initially produced neuromuscular facilitation that was most pronounced after 20–40 min with the highest concentration; this facilitation was followed by progressive blockade that was greatest with the two highest concentrations (∼100% blockade with 30 μg/ml after a 120 min incubation) (Fig. 2A). Incubation of mouse diaphragm muscle with venom (30 μg/ml) resulted in a marked increase in quantal content in the first 30 min that correlated with the facilitation seen in the twitch-tension response after venom addition; at later periods (≥90 min, when the blockade was >80%) the quantal content was significantly lower than the basal (pre-venom) values (Fig. 2B). Incubation with venom (30 μg/ml) did not significantly alter the resting

membrane potential after 120 min (control: −81 ± 0.8 mV vs. venom: −74 ± 1.8 mV, n = 5 each). In Anidulafungin (LY303366) contrast, exposure of the preparation to carbachol (68 μM) in the presence of venom resulted in membrane depolarization (from −83 ± 0.2 mV to −63 ± 2 mV after 15 min and a return to pre-venom values, −81 ± 0.1 mV, after washing), indicating normal functioning of the postsynaptic nicotinic receptors. Considering that many Bothrops PLA2 that produce neuromuscular blockade are sensitive to low temperature (a reduction from 37 °C to 24–22 °C) ( Cogo et al., 1998 and Gallacci and Cavalcante, 2010), we examined the influence of low temperature on the neuromuscular responses to B. b. smargadina venom. In chick biventer cervicis preparations, incubation at 22 °C delayed the onset of neuromuscular blockade; at a venom concentration of 10 μg/ml complete blockade occurred in ∼30 min at 37 °C, whereas at 22 °C the maximum blockade observed after 120 min was ∼70%. This reduced potency was reflected in the time required for 50% blockade (∼15 min at 37 °C and ∼105 min at 22 °C).

As scientists from diverse disciplines improve the ability to quantify rates and magnitudes of diverse fluxes, it becomes increasingly clear that the majority of landscape change occurs during relatively short periods of time and that some portions of the

landscape are much more dynamic than other portions, as illustrated by several examples. Biogeochemists describe a short period of time with disproportionately high reaction rates relative to longer intervening time periods as a hot moment, and a small area with disproportionately high reaction rates relative ATM/ATR mutation to the surroundings as a hot spot (McClain et al., 2003). Numerous examples of inequalities in time and space exist in the geomorphic literature. More than 75% of the long-term sediment flux from mountain rivers in Taiwan occurs less than 1% of the time, during typhoon-generated floods (Kao and Milliman, 2008). Approximately 50% of the suspended sediment discharged by rivers of the Western Transverse Ranges of California, USA comes from the 10% of the basin underlain by weakly consolidated bedrock (Warrick and Mertes, 2009). Somewhere between 17% and 35% of the total particulate organic carbon flux to the world’s oceans comes from high-standing islands in

the southwest Pacific, which constitute only about 3% of Earth’s landmass (Lyons et al., 2002). One-third of the total amount of stream energy generated by the Tapi River of India during the monsoon season is expended INCB018424 manufacturer on the day of the peak flood (Kale and Hire, 2007). Three-quarters of the carbon

stored in dead wood and floodplain sediments along headwater mountain stream networks MRIP in the Colorado Front Range is stored in one-quarter of the total length of the stream network (Wohl et al., 2012). Because not all moments in time or spots on a landscape are of equal importance, effective understanding and management of critical zone environments requires knowledge of how, when, and where fluxes occur. Particularly dynamic portions of a landscape, such as riparian zones, may be disproportionately important in providing ecosystem services, for example, and relatively brief natural disturbances, such as floods, may be disproportionately important in ensuring reproductive success of fish populations. Recognition of inequalities also implies that concepts and process-response models based on average conditions should not be uncritically applied to all landscapes and ecosystems. Geomorphologists are used to thinking about thresholds. Use of the term grew rapidly following Schumm’s seminal 1973 paper “Geomorphic thresholds and complex response of drainage systems,” although thinking about landscape change in terms of thresholds was implicit prior to this paper, as Schumm acknowledged.

) and by carrying out research and other activities (Carrefour, 2003). Connected to this forum, the European Dry Stone Walls Project was changed to create a European network, which built on inter-regional co-operation for local development based on dry-stone walls inheritance. In Italy in 2005, the ALPTER project was built to counteract the abandonment of terraced agricultural areas in the alpine region of Europe, a problem that only recently has raised the attention of both institutions

and citizens, due to the loss of cultural heritage and the natural hazards it can produce. The project, co-financed in the framework of the EU program Interreg Alpine Space, began in 2005 with the collection of data on eight terraced areas, aimed at defining procedures for mapping, assessing geological hazards, enhancing agricultural production Histone Methyltransferase inhibitor and promoting tourism in terraced zones (ALPTER). In 2010, the First Terraced Landscapes World Conference took place in Yunnan (China), gathering not only scholars but also indigenous peoples from all over the world

to bring together knowledge and operative selleck products perspectives about the terraced landscapes worldwide (Du Guerny and Hsu, 2010). After the conference, the participants established the International Alliance for Terraced Landscapes (ITLA), working to connect existing projects worldwide with regard to the conservation and revitalization of terraced areas. These forums and projects are examples of non-structural measures for terraces management. They share the recognition and preservation of traditional terracing procedures thanks to the gathering of professionals and scholars

around agreements in the context of National or International associations. They also propose the development and improvement of basic and advanced training for young people, based on reference knowledge that can be transferred to other regions acetylcholine of Europe or to other countries worldwide. Other non-structural measures should comprise local action programmes that integrate terrace heritage into local development strategies, by raising the awareness of young people and adult volunteers in the countries involved in the programmes, with practical field-based activities. Pilot activities for the restoration of terraces should be pursued as well, such as model work sites that can both preserve threatened heritage items (walls) and be used to train professionals in traditional building methods. Terrace maintenance can also benefit directly from the return of this peculiar landscape (tourism, or cultural and leisure activities), or indirectly (commerce of the products) from the improvement of agricultural production from the maintenance of active rural people and from the involvement of youth in terrace management and maintenance.
