    AbstractTerrestrial gross primary productivity (GPP) quantifies the photosynthetic uptake by vegetation and it is the largest component of the terrestrial carbon cycle. The separation of sunlit and shaded leaves has been shown to be an effective leaf‐to‐canopy upscaling method for modeling vegetation GPP. In this study, the performance of the Integrated Carbon‐Canadian Land Surface Scheme (IC‐CLASS) based on Farquhar's photosynthetic model and the two‐leaf approach was compared against that of Moderate Resolution Imaging Spectroradiometer (MODIS) GPP algorithm using the light use efficiency (LUE) approach, validated with eddy covariance (EC) measured GPP over a variety of terrestrial ecosystems in Canada. There were systematic differences between the IC‐CLASS simulated GPP and the MODIS GPP product in spatial distribution patterns. The differences were due to inherent shortcomings of the LUE modeling approach where a constant maximum LUE value is specified for each biome type, ignoring the variation of shaded leaf contribution to total GPP. The IC‐CLASS model separates the sunlit and shaded leaves and the bias in simulating GPP was minimized. The IC‐CLASS performed better than the MODIS GPP algorithm compared with monthly and annual GPP derived from EC flux data at 13 Canadian Carbon Program sites. The differences between the IC‐CLASS and the MODIS GPP estimates were larger in more clumped canopies (i.e. forests), because of the increase in the shaded leaf fraction. Different LUEs in sunlit and shaded portions of the canopy should be considered for effective and reliable estimation of GPP at regional scale.

    Abstract We used stationary matrix models to assess size–class dynamics of a protected neotropical gallery forest in Central Brazil, and tested their predictive capacity for different calibration periods. Data series comprised of all trees (with diameter ≥ 10 cm) registered in 151 (10 m × 20 m) permanent plots in the years of 1985, 1988, 1991, 1994, 1999, 2004, and 2009. Demographic and diameter growth rates fluctuated, and recruitment slightly decreased after 1991. All models produced reliable ( P > 0.05) short-term projections (≤10 years). However, models calibrated before 1991 produced unreliable >10-year projections. The model calibrated over the 1991–1994 period reliably predicted size–class structure after 5 consecutive 3-year simulations (15 years). Results show that short-term (10-year) size–class structure of protected neotropical rainforests can be reliably predicted using stationary matrix models; and that predictions are slightly sensitive to the calibration period. Although stand dynamics were variable and affected by environmental stochasticity, size–class structural dynamics remained close to constant after 1991, since all projections from stationary models calibrated after that year were similar to the observed data ( P > 0.05). This indicates that, under the recent levels of natural disturbances, the forest has maintained stability in the size–class dynamics.

    Abstract The penetration of various amino acids and dipeptides through porcine skin was measured in vitro in this work to examine the effect of lipophilicity and molecular weight of the compounds on the permeability of passive diffusion. Experimental results indicated that the effect of lipophilicity is a more dominant factor than the molecular weight. An equation was also developed to accurately predict the permeability of amino acids and dipeptides based on the lipophilicity of penetrants as follows: log Kp = −2.73+0.38ln K−0.036(ln K)2 with R2 of 0.85 for the regression, where K, the lipophilicity, is represented by the partition coefficients of amino acids and dipeptides between the PEG/Na2SO4 aqueous two-phase system. In particular, the successful prediction of partition coefficients of dipeptides by Chen's method was used to further predict the dipeptides' permeability for transdermal delivery. The experimental results were deemed satisfactory.

    Abstract The pear cultivars ‘Spadona Estiva’, ‘Coscia’, ‘Beurre Superfin’ and a ‘Bartlett’ clone of South African origin (termed ‘Bartlett Sport’) were tested on 5 quince rootstock types, 5 Pyrus species and on 5 or 30 cm long interstocks of the pear cultivars ‘Bergamotte Esperen’ and ‘Spadona Estiva’ on quince MA, while ‘Dr. Jules Guyot’ was used as an interstock on ‘Bartlett’ seedlings. At the age of 10 years only ‘Spadona Estiva’ showed no signs of decline on quince rootstocks, ‘Coscia’ showed moderate decline, while the remaining cultivars had already declined severely. When the trunk circumference of ‘Beurre Superfin’ trees on the various quince clones was taken as an indicator for the degree of graft incompatibility, a negative correlation was found between this parameter and cyanogenic glycoside content in the stem bark of ungrafted quince plants belonging to the same clones. Pear interstocks on quince MA rootstocks did in some cases increase crops compared to the same quince alone, but did not prevent the decline of ‘Beurre Superfin’ and Bartlett Sport' on quince. The most vigorous and most prolific rootstock was Pyrus betulaefolia . However, with ‘Spadona Estiva’ differences in vigor between the rootstocks were only small and crops on the Israeli quince CI 7 were similar to those on Pyrus betulaefolia , but fruit size was larger on quince. Cropping of this cultivar at the age of 4 years was closely related to the intensity of flowering, whereas with ‘Coscia’ this relation was much less evident. Leaf fall in autumn and the opening of the vegetative buds of ‘Beurre Superfin’ in spring were earlier on quince than on Pyrus rootstocks.

    The effects of delayed bale wrapping on fermentation characteristics, preservation and quality of whole barley crop ensiled as large bales (LBS) were examined. Forage was cut at the early milk stage and allowed to wilt over 24-h period to 47% DM. Bales were allocated to one of three treatments requiring that bales be wrapped within 2, 10 and 19 h post-baling. Bales were sampled at baling and on days 1, 2, 3, 6, 9, 13, 17, 29, 64, 92, 252 and 308 post-baling. Bales were weighed prior to being wrapped and when removed from storage to measure DM and nutrient losses during storage. During wrapping, a thermocouple wire was inserted in each bale to monitor bale temperature. Bales wrapped within 2 and 10 h were similar (P > 0.05) for storage temperature, nutrient profile and recovery, and for lactic and volatile fatty acid content. Lactic acid concentrations peaked between 29 and 64 d post-ensiling for bales wrapped 2 and 10 h post-bailing, but did not peak until day 92 for bales wrapped at 19 h post-bailing. Storage temperature of bales wrapped after 2 and 10 h post-bailing did not exceed 30 °C during storage, but bales wrapped 19 h later exceeded 30 °C for the first 19 d during storage. Bales wrapped within 19 h had a lower (P < 0.05) water soluble carbohydrate content and a higher acid detergent insoluble N and ammonia N level compared to 2 and 10 h bales. The pH and 2, 3 butanediol levels were higher (P < 0.01) in 19 h compared to 2 and 10 h bale silage. A 64 d ensiling period was required to achieve minimum pH values in LBS wrapped with 10 h post-baling, the length of time being greater when wrapping was delayed to 19 h post-baling. Results from this study indicate that delaying bale wrapping to the next day resulted in a temperature rise, and poor silage protein quality. Wrapping 2 h post-baling was not an advantage to wrapping 10 h post-baling in whole crop barley ensiled as large bales. Key words: Silage, large bale, whole crop barley, delayed wrapping, ensiling characteristics

    Abstract Glomalin, a substance produced by arbuscular mycorrhizal fungi, is reported to play a role in soil aggregation, but this role has been questioned in soils rich in calcium carbonate. We studied the relationship between aggregation stability and glomalin in a Haplic Calcisol comparing abandoned and active cultivation of olive groves. Abandonment was associated with increases in soil organic carbon, the percentage of water stable aggregates (WSA 1–2mm ), and easily extractable and total Bradford-reactive soil protein. WSA 1–2mm was strongly positively correlated with both easily extractable and total Bradford-reactive soil protein. While easily extractable Bradford-reactive soil protein measured in both stable and unstable aggregates did not show any significant differences, Bradford-reactive soil protein was twice as high in stable than in unstable aggregates under both tillage and abandonment. Our results suggest that Bradford-reactive soil protein influences aggregate stability, even in soils with low organic matter and high calcium carbonate contents. However, more research is needed to elucidate the role of easily extractable Bradford-reactive soil protein in soil aggregation.

    Peat is a non-renewable resource and its extraction contributes to the degradation of wetland ecosystems. In order to reduce the peat use in nursery, two composts prepared from yard wastes were evaluated as a substrate component for producing vegetable seedlings for transplantation. Two experiments with tomato (Solanum lycopersicum L.) cultivars ‘Naxos’ and ‘TCP 9147’ and pepper (Capsicum annuum L.) cultivars ‘Solero’ and ‘Logos’ were set up in a greenhouse. In each experiment two composts were tested: “Cp”, obtained from yard wastes + beached residues of marine plant posidonia [Posidonia oceanica (L.) Delile – 20% of total fresh weight], and “C”, obtained only from yard wastes. Each compost was mixed with commercial peat in the amount of 0 (control), 25, 50, 75 and 100% (v/v). Results from the study suggest that, for both species, the best yield was obtained with the substrate prepared by mixing the peat with 25% of Cp.

    ABSTRACTIn the processing of pig carcasses after slaughter the scapulae are removed mechanically. It is economically important to minimize the proportion of fractures (2 to 4%) that occur during this operation. The incidence of fractures in several hundred scapulae was investigated with a strain testing machine modified to simulate production-line techniques. The proportion of fractures occurring on the line was consistent with the relationship between the standard force employed and the standard deviation of the normal variation of the fracture load about its mean. In an attempt to raise the mean fracture load by reducing the maximum contact stress, the contact radius of the withdrawing tool was increased; this did not significantly change the mean fracture load but significantly decreased its variation.

    AbstractTerrestrial gross primary productivity (GPP) quantifies the photosynthetic uptake by vegetation and it is the largest component of the terrestrial carbon cycle. The separation of sunlit and shaded leaves has been shown to be an effective leaf‐to‐canopy upscaling method for modeling vegetation GPP. In this study, the performance of the Integrated Carbon‐Canadian Land Surface Scheme (IC‐CLASS) based on Farquhar's photosynthetic model and the two‐leaf approach was compared against that of Moderate Resolution Imaging Spectroradiometer (MODIS) GPP algorithm using the light use efficiency (LUE) approach, validated with eddy covariance (EC) measured GPP over a variety of terrestrial ecosystems in Canada. There were systematic differences between the IC‐CLASS simulated GPP and the MODIS GPP product in spatial distribution patterns. The differences were due to inherent shortcomings of the LUE modeling approach where a constant maximum LUE value is specified for each biome type, ignoring the variation of shaded leaf contribution to total GPP. The IC‐CLASS model separates the sunlit and shaded leaves and the bias in simulating GPP was minimized. The IC‐CLASS performed better than the MODIS GPP algorithm compared with monthly and annual GPP derived from EC flux data at 13 Canadian Carbon Program sites. The differences between the IC‐CLASS and the MODIS GPP estimates were larger in more clumped canopies (i.e. forests), because of the increase in the shaded leaf fraction. Different LUEs in sunlit and shaded portions of the canopy should be considered for effective and reliable estimation of GPP at regional scale.

    Abstract We used stationary matrix models to assess size–class dynamics of a protected neotropical gallery forest in Central Brazil, and tested their predictive capacity for different calibration periods. Data series comprised of all trees (with diameter ≥ 10 cm) registered in 151 (10 m × 20 m) permanent plots in the years of 1985, 1988, 1991, 1994, 1999, 2004, and 2009. Demographic and diameter growth rates fluctuated, and recruitment slightly decreased after 1991. All models produced reliable ( P > 0.05) short-term projections (≤10 years). However, models calibrated before 1991 produced unreliable >10-year projections. The model calibrated over the 1991–1994 period reliably predicted size–class structure after 5 consecutive 3-year simulations (15 years). Results show that short-term (10-year) size–class structure of protected neotropical rainforests can be reliably predicted using stationary matrix models; and that predictions are slightly sensitive to the calibration period. Although stand dynamics were variable and affected by environmental stochasticity, size–class structural dynamics remained close to constant after 1991, since all projections from stationary models calibrated after that year were similar to the observed data ( P > 0.05). This indicates that, under the recent levels of natural disturbances, the forest has maintained stability in the size–class dynamics.

    Abstract The penetration of various amino acids and dipeptides through porcine skin was measured in vitro in this work to examine the effect of lipophilicity and molecular weight of the compounds on the permeability of passive diffusion. Experimental results indicated that the effect of lipophilicity is a more dominant factor than the molecular weight. An equation was also developed to accurately predict the permeability of amino acids and dipeptides based on the lipophilicity of penetrants as follows: log Kp = −2.73+0.38ln K−0.036(ln K)2 with R2 of 0.85 for the regression, where K, the lipophilicity, is represented by the partition coefficients of amino acids and dipeptides between the PEG/Na2SO4 aqueous two-phase system. In particular, the successful prediction of partition coefficients of dipeptides by Chen's method was used to further predict the dipeptides' permeability for transdermal delivery. The experimental results were deemed satisfactory.

    Abstract The pear cultivars ‘Spadona Estiva’, ‘Coscia’, ‘Beurre Superfin’ and a ‘Bartlett’ clone of South African origin (termed ‘Bartlett Sport’) were tested on 5 quince rootstock types, 5 Pyrus species and on 5 or 30 cm long interstocks of the pear cultivars ‘Bergamotte Esperen’ and ‘Spadona Estiva’ on quince MA, while ‘Dr. Jules Guyot’ was used as an interstock on ‘Bartlett’ seedlings. At the age of 10 years only ‘Spadona Estiva’ showed no signs of decline on quince rootstocks, ‘Coscia’ showed moderate decline, while the remaining cultivars had already declined severely. When the trunk circumference of ‘Beurre Superfin’ trees on the various quince clones was taken as an indicator for the degree of graft incompatibility, a negative correlation was found between this parameter and cyanogenic glycoside content in the stem bark of ungrafted quince plants belonging to the same clones. Pear interstocks on quince MA rootstocks did in some cases increase crops compared to the same quince alone, but did not prevent the decline of ‘Beurre Superfin’ and Bartlett Sport' on quince. The most vigorous and most prolific rootstock was Pyrus betulaefolia . However, with ‘Spadona Estiva’ differences in vigor between the rootstocks were only small and crops on the Israeli quince CI 7 were similar to those on Pyrus betulaefolia , but fruit size was larger on quince. Cropping of this cultivar at the age of 4 years was closely related to the intensity of flowering, whereas with ‘Coscia’ this relation was much less evident. Leaf fall in autumn and the opening of the vegetative buds of ‘Beurre Superfin’ in spring were earlier on quince than on Pyrus rootstocks.
