Abstract:

Summary The colour of Sapelli heartwood (Entandrophragma cylindricum Sprague) is variable depending on habitat. In recent years an unusual pinkish-brown colour has been observed in commercial sawn timber of this species from Central Africa. Initial studies of Sapelli heartwood samples from various provenances have furthermore demonstrated pronounced differences in its decay resistance. Heartwood extractive composition varies considerably between provenances. Samples of Sapelli heartwood from the Central African Republic (RCA) contained 6.4% by weight of extractives compared with 12.5% for those from Cameroon and four other provenances investigated. UV microspectrophotometric analysis of heartwood extractives was used to localise phenolic extractives within wood cell walls and to identify their distribution at tissue level. The S2 and S3 wall layers of vessels and fibres in the heartwood were discriminated from sapwood by their high concentration of non-lignin phenolic extractives. These extractives in the cell walls were also found to be variable. As UV absorption properties show, the vessel and fibre secondary walls of Cameroon heartwood had a considerably higher concentration of extractives in comparison with samples from the RCA. In sapwood, the UV absorption levels for the fibre S2 layer and the vessel S3 layer were independent of the extraction procedure, suggesting the phenolic extractives in this part of the trunk were in low concentrations. Furthermore it is suggested that polyphenols constitute part of the cell wall matrix. The non-extractable phenolic content was found to be independent of provenances as demonstrated by wood from Cameroon and the RCA. The natural durability of Sapelli heartwood against fungal decay appears to be dependent on the extractive composition and on their concentration in the fibre tissue.

Abstract:

Summary The decay patterns of brown and soft rot fungi in Sapelli wood (Entandrophragma cylindricum Sprague), with respect to natural durability, were examined by light and transmission electron microscopy as well as UV spectroscopy. Analyses revealed that the typical brown rot fungus Coniophora puteana can cause a soft rot-like decay in the sapwood of Sapelli at high moisture contents of approx. 100%. In accordance with the decay pattern of the typical soft rot fungus Chaetomium globosum, the hyphae of C. puteana penetrated the S2 wall of fibres and formed characteristic rhomboidal cavities orientated parallel to the microfibrillar angle. However, these cavities were larger in diameter (3.9 μm ± 0.9) than those formed by C. globosum (2.1 μm ± 0.5) and with a distinct interspace between the hyphae and surrounding walls. Hyphae of C. globosum were directly attached to the undecayed secondary wall. No lignin degradation for both fungi in close vicinity to the cavities was observed, as evidenced by UV spectroscopy. The inclusion of microscopy for definitive decay type identification is recommended.

Abstract:

La rythmicité intra-annuelle de la crois- sance diamétrique des arbres n’est connue que pour très peu d’espèces tropicales africaines. Dans cet article, une combinaison de méthodes expéri- mentant le marquage cambial séquen- tiel, l’analyse anatomique et la mesure des cernes a été utilisée pour détermi- ner la périodicité et les variations de la croissance diamétrique de trois espèces d’Afrique centrale produisant un bois d’œuvre de grande qualité : Baillonella toxisperma (moabi), Entandrophragma cylindricum (sapelli) et Erythrophleum suaveolens (tali). En outre, des interac- tions avec la phénologie foliaire et repro- ductive et le climat ont été recherchées. Pour les trois espèces, les cernes de croissance sont anatomiquement dis- tincts, annuels et se forment au rythme des saisons, avec un accroissement qui est maximal pendant la petite saison pluvieuse (de mars à mai). Les variations saisonnières de la croissance se sont avérées significatives pour le moabi et le sapelli et non significatives pour le tali. Les paramètres climatiques jouant un rôle déterminant dans ces variations sont la température et l’ensoleillement. L’ana- lyse dendrochronologique dresse d’inté- ressantes perspectives en vue d’acquérir des données de croissance sur le long terme, nécessaires à la définition des paramètres de gestion des populations naturelles de ces espèces.

Abstract:

Interesting aesthetic properties of tropical woods, like surface texture and colour, are rarely impaired due to weathering, rotting and other degradation processes. This study analyses the colour of 21 tropical woods before and after six weeks of intentional attack by the brown-rot fungus Coniophora puteana. The CIEL*a*b* colour system was applied for measuring the lightness, redness and yellowness, and from these parameters the hue tone angle and colour saturation were calculated. Lighter tropical woods tended to appear a less red and a more yellow, and had a greater hue tone angle. However, for the original woods was not found dependence between the lightness and colour saturation. Tropical woods at attack by C. puteana lost a weight from 0.08% to 6.48%. The lightest and moderately light species—like okoumé, iroko, ovengol and sapelli—significantly darkened, while the darkest species—wengé and ipé—significantly lightened. The majority of tropical woods obtained a brighter shade of yellow, typically wengé, okoumé and blue gum, while some of them also a brighter shade of green, typically sapelli, padouk and macaranduba. C. puteana specifically affected the hue tone angle and colour saturation of tested tropical woods, but without an apparent changing the tendency of these colour parameters to lightness. The total colour difference of tested tropical woods significantly increased in connection with changes of their lightness (ΔE*ab = 5.92 − 0.50·ΔL*; R2 = 0.37), but it was not influenced by the red and yellow tint changes, and weight losses.

Abstract:

Due to the extinction of some wood species used to manufacture guitars, there is a trend to search new alternative materials with the same acoustic performance. There is a wide range of tonewoods: ebony, rosewood, yellow and red cedar, mongoy and sapelli, among others. These woods have high resonance qualities and the requirements are both acoustical and mechanical. In this work, alternative composite materials have been manufactured to compare dynamic and psychoacoustic parameters with the commonly used woods. This comparison will allow to conclude the possibility of using these materials as substitutive of tonewoods.

Abstract:

En Afrique centrale, l’aménagement fores- tier repose sur une méthode de simulation de la production forestière peu précise, susceptible d’hypothéquer la durabilité de l’exploitation. L’objectif de cette étude est d’améliorer la prédiction de la crois- sance pour quatre essences commerciales importantes en Afrique centrale. Le dispo- sitif d’étude a été installé dans le Sud-Est du Cameroun et comporte 387 arbres : 136 assamela (Pericopsis elata), 54 moabi (Baillonella toxisperma), 124 sapelli (En- tandrophragma cylindricum), et 73 tali (Erythrophleum suaveolens). Le diamètre a été mesuré régulièrement entre 2009 et 2012. L’intensité de la compétition a été quantifiée à l’échelle d’une placette circu- laire de 20 m de rayon installée autour de chaque arbre focal. Les caractéristiques to- pographiques et hydrologiques ont été esti- mées à l’aide d’un système d’information géographique. La croissance a été modéli- sée en intégrant le diamètre des arbres et les conditions de croissance (indice de com- pétition et environnement local). Les valeurs d’accroissement utilisées actuellement au Cameroun ne sont pas différentes des va- leurs observées en forêt non perturbée par l’exploitation forestière pour l’assamela, le moabi et le tali, mais surestiment la crois- sance de 20 % pour le sapelli. Un modèle log-normal intégrant le diamètre des arbres et l’intensité de la compétition permet d’es- timer l’accroissement des quatre essences avec un coefficient de détermination (R2) va- riant de 0,092 pour l’assamela à 0,47 pour le moabi. Les variables topographiques et hydrologiques ne permettent pas d’amé- liorer significativement la qualité des pré- dictions. Ces modèles peuvent être utilisés pour prédire l’accroissement à partir des données d’inventaires forestiers d’aména- gement tels qu’ils sont réalisés en Afrique centrale, en vue d’améliorer la définition de paramètres de gestion tels que le dia- mètre minimum d’exploitation ou le taux de reconstitution pour les quatre essences étudiées.

Abstract:

La economía laboral, que atiende asuntos relativos a la oferta y la demanda de empleo y los salarios, es un asunto que en palabras del profesor Sapelli (2007), ha sufrido cambios rotundos en los últimos años. En el presente artículo se presentan algunas posiciones clásicas, neoclásicas e institucionalistas respecto a las formas de integración y programas económicos que ofrecen soluciones relativas a las variables económico-laborales. El diálogo parte de los aportes de la Escuela de Chicago esbozando a manera general la Teoría del Capital Humano, que encuentran eco en las políticas neoliberales, pero que choca con los postulados marxistas y neoinstitucionalistas que señalan rutas alternas. Del estudio se concluye la necesidad de llegar a una vía intermedia en la acepción del papel del Estado frente a dos variables claves: la educación y la inversión.

Abstract:

The bonding of wood with assembly adhesives is crucial for manufacturing wood composites, such as solid wood panels, glulam, furniture parts, and sport and musical instruments. This work investigates 13 hardwoods—bangkirai, beech, black locust, bubinga, ipé, iroko, maçaranduba, meranti, oak, palisander, sapelli, wengé and zebrano—and analyzes the impact of their selected structural and physical characteristics (e.g., the density, cold water extract, pH value, roughness, and wettability) on the adhesion strength with the polyvinyl acetate (PVAc) adhesive Multibond SK8. The adhesion strength of the bonded hardwoods, determined by the standard EN 205, ranged in the dry state from 9.5 MPa to 17.2 MPa, from 0.6 MPa to 2.6 MPa in the wet state, and from 8.5 MPa to 19.2 MPa in the reconditioned state. The adhesion strength in the dry state of the bonded hardwoods was not influenced by their cold water extracts, pH values, or roughness parallel with the grain. On the contrary, the adhesion strength was significantly with positive tendency influenced by their higher densities, lower roughness parameters perpendicular to the grain, and lower water contact angles.

Abstract:

Writing and researching Southern Europe as a symbiotic area has always presented a challenging task. Historians and political scientists such as Stanley Payne, Edward Malefakis, Giulio Sapelli, and Roberto Aliboni have studied the concept of Southern Europe and its difficult paths to modernity. They have been joined by sociologists and anthropologists who have debated the existence of a Southern European paradigm in the nineteenth and twentieth centuries and the arduous transformation of the region's welfare systems, economic development, education and family structures. These scholarly attempts to understand the specificities of Southern Europe date back to the concerns of Western European Cold War strategists in the 1970s, many of whom were worried about the status quo of the region in the aftermath of the fall of the dictatorships. But this geographical and geopolitical definition of the area did not necessarily follow existing cultural, political and economic patterns. Once the Eurozone crisis hit in the 2000s these questions came back with renewed force but with even less conceptual clarity, as journalists and pundits frequently gestured towards vague notions of what they considered to be ‘Southern Europe’.

Abstract:

The biological resistance of 21 tropical wood species against bacteria and molds was studied. The gram-positive bacterium Staphylococcus aureus and the gram-negative bacterium Escherichia coli had none or negligible activity on surfaces of zebrano and maçaranduba (up to 1 ×106 CFU/mL), and they had negligible or medium activity on surfaces of macassar ebony, ovengol, santos rosewood, and iroko (from 1 ×106 up to 1 ×107 CFU/mL). These bacteria had high activity on surfaces of okoumé, tineo, doussié, makoré, and both reference woods, beech and Scots pine (usually over 1 ×107 CFU/mL). The mold growth activity (MGA) of Aspergillus niger and Penicillium brevicompactum was minimal on surfaces of ipé, yellow balau, macassar ebony, doussié, bubinga, and merbau, but it was strong on surfaces of okoumé, cerejeira, ovengol, wengé, sapelli, and both reference woods. When comparing individual biological tests of (a) bacterial and mold but also (b) bacterial, mold and rot with decaying fungi C. puteana and T. versicolor, no significant relationships were found. These results confirm that the bio-durability of woods is influenced not only by their molecular structure, but also by the attacking biological pest group.

Abstract:

Este artigo apresenta, à luz da Educação do Campo, uma prática pedagógica vivenciada em uma escola urbana, lotada no município de Dom Pedrito/RS, que recebe alunos oriundos do campo. Tem-se por objetivo descrever um experimento pedagógico realizado durante o Estágio Supervisionado Obrigatório nos anos finais do Ensino Fundamental, que teve como suporte o planejamento por Complexo de Estudo (CALDART; FREITAS; SAPELLI, 2015). Trata-se da prática docente em uma perspectiva social, inclusiva e participativa, fazendo uso da ferramenta “Inventário da Realidade Social”. De acordo com os dados coletados e análise dos mesmos, foi possível destacar elementos balizadores para a elaboração do complexo de estudo, que procurou abranger a grande totalidade da comunidade escolar e comunidades rurais atendidas pela referida escola. O experimento pedagógico teve como tema principal o trabalho socialmente útil, o qual deu origem ao projeto “Aluno Integrado” que oportunizou a estudantes rurais e urbanos o convívio participativo e atuante na escola, contribuindo com o processo formativo nos âmbitos pedagógico e social. Assim, esta experiência evidenciou fatores relevantes entre a dicotomia rural e urbana, apresentando a escola como espaço gerador na construção dos múltiplos saberes. Buscou-se, para além do conhecimento cognitivo, a valorização do contexto social em que o aluno está inserido. Como resultado, foi possível à comunidade escolar experienciar um olhar amplo à perspectiva educacional, percebendo o aluno como um todo, dando a devida importância à sua presença nesta escola.Palavras-chave: Complexo de estudo; Educação do campo; Trabalho socialmente útil. ABSTRACT: This article presents, it up the Coutryside Education, a pedagogical practice experienced in a crowded school urban in the municipality of Dom Pedrito / RS, which receives students from the countryside. The objective is to report and present a pedagogical experiment carried out during the Mandatory Supervised Internship in the last years of Elementary Education, which was supported by the Complex Study Plan (CALDART; FREITAS; SAPELLI, 2015). It is the teaching practice in a social, inclusive and participatory perspective, making use Social Reality Inventory tool. According to the data collected and the analysis of these, it was possible to highlight elements for the elaboration of the study complex, which sought to cover the great totality of the school community and rural communities served by refered school. The pedagogical experiment had as its main theme the socially useful work, this gave rise to the project "Integrated Student" that gave rural and urban students the participative and active living in the school, contributing to the pedagogical and social formative process of them. Thus, this pedagogical experience evidenced relevant factors between the rural and urban dichotomy, presenting the school as generating space in the construction of multiple knowledge. It was noticed that this one contemplated not only the cognitive knowledge but also the social context in which the student is inserted, allowed the school community a broad view in the educational perspective valuing the student as a whole, giving due importance to their presence in this school.Keywords: Study complex; Coutryside education; Socially useful work.

Abstract:

En zone tropicale humide, la valeur des systèmesagroforestierspour lesagriculteurs est souvent difficile à évaluer. À partir d’un inventaire floristique réalisé dans 14 cacao- yères agroforestières du Centre-Cameroun, l’article propose leur évaluation participative basée sur la méthode de distribution des cailloux mobilisée pour quantifier la valeur accordée par les agriculteurs à chaque espèce en fonction des usages attribués. Au total, 86 espèces ligneuses ont été inventoriées. Les cinq espèces les plus fré- quentes ont été le safoutier, Dacryodes edulis, avec 18 % des arbres inventoriés, l’avocatier, Persea americana, avec 11 %, le fraké, Terminalia superba, avec 10 %, le figuier, Ficus mucoso, avec 5 %, et Albizia adianthifolia, avec 3 %. Vingt-deux espèces (26 %) n’ont eu aucun usage pour les agri- culteursqui ont défini sept usagesdifférents pour lesautresespècesinventoriées. Parmi cesespèces, la valeur d’usage la plusélevée a été attribuée au cacaoyer (20 %).

Abstract:

The Comprehensive Commercial Logging Ban in All Natural Forests (CCLB) policy, introduced in April 2015, aims to protect all natural forests in China. It has impacted both China’s domestic timber supply and imports. We investigated price transmission in China’s hardwood lumber imports resulting from the implementation of this policy. We selected three hardwood lumber species, i.e., Sapelli (Entandrophragma), Mandshurica (Fraxinus), and Laurel (Terminalia), and used their daily prices from 30 April 2015 to 30 November 2017. Threshold co-integration and threshold error correction models are employed for this analysis. We identified a structural breakpoint on 30 November 2016, and consequently partitioned the data series into two parts for the two subperiods separated by the breakpoint. The empirical results indicated that there was asymmetric price transmission (APT) for both subperiods. Adjustment of positive price deviations to the long-term equilibrium levels was slower than that of negative price deviations. In the short term, the price of high-quality lumber evolved independently, whereas the price of lower-quality lumber tended to return to the equilibrium. The APT reflects a redistribution of welfare, benefiting the exporters more than the importers. We find that positive discrepancies in each price pair were inclined to be more persistent in the first subperiod than in the second subperiod. This could attribute to the fact that the degree of CCLB intervention in the former one was higher than in the latter one.

Abstract:

L'utilisation des tarifs de cubage fait partie du quotidien des aménagistes et gestionnaires forestiers. Toutefois, elle se fait généralement au mépris des conditions d'application (zone géographique, gamme de diamètres), ce qui peut engendrer des erreurs dans les estimations de volume. L'objectif de cette étude est de tester la validité des tarifs de cubage actuellement disponibles pour trois essences des forêts du sud-est du Cameroun, dont ceux utilisés par l'administration nationale et, le cas échéant, de proposer des tarifs adaptés pour la zone d'étude. Trois espèces commerciales sont concernées : le sapelli, Entandrophragma cylindricum, le tali, Erythrophleum suaveolens, et l'assaméla, Pericopsis elata. Les données dendrométriques ont été collectées par échantillonnage destructif de 43 arbres régulièrement répartis sur toute la gamme de diamètres. Le volume du fût a été calculé par la méthode des billons successifs et des tarifs de cubage linéaires et non linéaires ont été ajustés aux données par la méthode des moindres carrés pondérés. Les résultats montrent que le meilleur modèle de cubage est non linéaire pour les trois espèces. Les équations utilisées jusqu'à présent par l'administration forestière sous-estiment significativement le volume des arbres et les erreurs d'estimation sont d'autant plus grandes que la taille de l'arbre est importante. Les tarifs de cubage proposés, une fois validés, devraient pouvoir à l'avenir être utilisés pour une meilleure estimation du volume des arbres dans la zone d'étude. Considérant les enjeux internationaux auxquels adhère le Cameroun (FLEGT et REDD+), il est crucial de disposer d'outils performants d'estimation du volume des arbres. Dans ce contexte, il s'avère important que l'administration forestière camerounaise puisse mener à bien un vaste programme de révision des tarifs de cubage.

Abstract:

Abstract Benthic foraminifera are valuable environmental indicators of heavy metal contaminants in marine environments. To broaden their effectiveness as bioindicators, this study compares individually the effects of selected heavy metal contaminants, including both metabolically essential and non-essential elements, on temperate rotalids and subtropical miliolids, as well as associated monothalamid foraminifera. To accomplish these aims, assemblages of foraminifera were grown experimentally from propagules (small juveniles) collected from two coastal sites: Sapelo Island, Georgia, and Little Duck Key, Florida, that provide an effective comparison between environments and types of foraminifera. Surface sediment was collected from both locations and sieved immediately after collection. Using the propagule method, assemblages of foraminifera were grown in the laboratory from propagules in the sediment samples. Two metabolically essential trace elements, nickel, and zinc, and two non-essential elements, arsenic and cadmium were used to represent both types of heavy metal. Experimental conditions were held constant while varying only the metal concentrations. In treatments from both origins, increasing concentrations of cadmium, nickel, and zinc led to decreases in abundance and diversity for the foraminifera. In addition, zinc, and to a lesser extent cadmium and nickel above certain concentrations, resulted in an increase of deformed tests among the foraminifera. Deformities occurred amongst the most common calcareous species from Sapelo island: Ammonia tepida and Haynesina germanica. Fewer deformities were observed in common calcareous species from Little Duck Key, the miliolids Quinqueloculina sabulosa and Quinqueloculina bosciana featured few deformities. Notably, monothalamid species such as Psammophaga sapela remained present at high metal concentrations. These results support previous research and reinforce the usefulness of rotalids such as A. tepida and H. germanica as bioindicators of heavy metal contamination as well as suggesting a possible use of monothalamids such as P. sapela in this manner.

Abstract:

Questo scritto parla dell'evento come occasione etica. L'evento non è ciò che accade ma ciò che nell'accadere ci chiama singolarmente alla scelta etica. Ciò che accade è solo l'occasione, l'occursus (B. Spinoza). L'evento richiede una situazione singolare di attenzione capace di raccogliere, in ciò che accade, un segno o "ciò che ci fa segno" (G. Deleuze). L'occasione (occursus) per questa riflessione è stata la vicenda Covid, con le conseguenze che ne sono derivate. È stata un "evento" o un semplice, terribile, occursus? Il secondo punto riguarda il tempo dell'evento: credo sia un tempo vuoto, una discontinuità, una frattura che contiene una domanda. L'istante (hexaiphnes) dell'evento convoca il soggetto a una scelta etica.

Abstract:

Two of the most salient anthropological questions regarding southeastern shell ring sites are related to the season(s) that they were occupied and whether or not the deposits represent monumental constructions and/or feasting remains. This paper addresses these questions through the analysis of growth band of clams (Mercenaria spp.) (N = 620) and stable oxygen isotope ratios of clam and oyster shells (Crassostrea virginica) (N = 58) at the Sapelo Island Shell Ring complex located on the Georgia coast, USA. The season of death and the samples' position in the shell matrix at Sapelo provide important information on the rate of shell deposition and the season(s) the site was occupied. These data support the view that at least some portion of the human population at Sapelo occupied the site year-round. Additionally, while it appears that two shell rings at the site formed through the gradual deposition and accumulation of daily subsistence, other areas evidence short term, large-scale, shellfish processing and may lend credence to the view that at some point shell rings become monuments, commemorating rituals and gatherings.

Abstract:

AbstractRecent events across many regions around the world have shown that short-term droughts (i.e., daily or weekly) with sudden occurrence can lead to huge losses to a wide array of environmental and societal sectors. However, the most commonly used drought indices can only identify drought at the monthly scale. Here, we introduced a daily scale drought index, that is, the standardized antecedent precipitation evapotranspiration index (SAPEI) that utilizes precipitation and potential evapotranspiration and also considers the effect of early water balance on dry/wet conditions on the current day. The robustness of SAPEI is first assessed through comparison with two typical monthly indices [Palmer drought severity index (PDSI) and standardized precipitation evapotranspiration index (SPEI)] and soil moisture, and then applied to tracking short-term droughts during 1961–2015 for the Pearl River basin in south China. It is demonstrated that SAPEI performs as well as SPEI/self-calibrating PDSI at the monthly scale but outperforms SPEI at the weekly scale. Moreover, SAPEI is capable of revealing daily drought conditions, fairly consistent with soil moisture changes. Results also show that many of the historical short-term droughts over the Pearl River basin have multiple peaks in terms of severity, affected area, and intensity. The daily scale SAPEI provides an effective way of exploring drought initiation, development, and decay, which could be conducive for decision-makers and stakeholders to make early and timely warnings.

Abstract:

Vidalia onions (Allium cepa) are a branded product of southeastern Georgia marketed under a federal marketing order. They are short-day, yellow onions with a Granex shape that are susceptible to a number of diseases postharvest, limiting the amount of time they can be marketed. Postharvest treatments and storage methods can help extend their marketability. Thus, the objective of this study was to evaluate these postharvest treatments and storage conditions on quality of three Vidalia onion varieties: ‘WI-129’, ‘Sapelo Sweet’, and ‘Caramelo’. All varieties were undercut, then either harvested immediately (zero cure), field cured (2 days), or forced-air heat cured (3 days at ≈37 °C) when judged mature. ‘WI-129’, ‘Sapelo Sweet’, and ‘Caramelo’ represent early, midseason, and late varieties, respectively. Bulbs were then sorted and stored in refrigerated storage [0–1 °C, 70% relative humidity (RH)], sulfur dioxide (SO2) (1000 mg·L−1 in 2010 and 5000 mg·L−1 in 2011, one time fumigation) followed by refrigeration, ozone (O3 (0.1–10 mg·L−1; continuous exposure, 0–1 °C, 70% RH), or controlled-atmosphere storage [3% oxygen (O2), 5% carbon dioxide (CO2), 0–1 °C, 70% RH]. After 2 and 4 months, bulbs were removed from storage, and evaluated after 1 and 14 days for quality and incidence of disorders. ‘Caramelo’ had the lowest percent marketable onions after curing in 2010, while ‘WI-128’ had the lowest percent marketable onions in 2011. There was a rain event immediately before harvesting ‘Caramelo’ that may have contributed to low marketability in 2010. Heat curing improved marketability for ‘Sapelo Sweet’ and ‘WI-129’ in 2010 compared with no curing. In 2011, heat curing resulted in more marketable onions for ‘Sapelo Sweet’ compared with no curing. Curing had no effect on ‘Caramelo’ in 2011 and field curing had the greatest percent marketable onions for ‘WI-129’ in 2011. In 2010, controlled-atmosphere storage had more marketable onions compared with SO2 for ‘Caramelo’ and was better than simple refrigeration or O3 with ‘WI-129’. In 2011 refrigeration, controlled-atmosphere storage, and O3 were all better than SO2 with ‘Caramelo’. ‘Sapelo Sweet’ and ‘WI-129’, on the other hand in 2011, had better storage with SO2 compared with other storage methods. Onions stored for 2 months had 32% and 17% more marketable onions after removal compared with 4 months of storage regardless of storage conditions for 2010 and 2011, respectively. Poststorage shelf life was reduced by about one-third, 14 days after removal from storage regardless of the storage conditions.

Abstract:

The question of whether the rise in CO2 levels observed during the industrial era has influenced the rates of tree biomass growth represents one of the main unsolved questions in the field of climate change science. In this framework, the African tropical forest represents one of the most important carbon (C) sinks, but detailed knowledge of its response to elevated CO2 is still lacking, especially regarding tree growth rate estimations. A major limitation to determining growth rates in the African tropical region is that many trees lack seasonality in cambial activity determining annual growth rings. In this study, several species of trees characterizing the African tropical forest have been investigated to estimate their biomass growth rate by means of a procedure based on 14C and growth models. A total of 71 subsamples were analyzed for a Entandrophragma cylindricum (sapele) tree, and 38 and 25 wood subsamples for Erythrophleum suaveolens (tali) and Triplochiton scleroxylon (ayous) trees, respectively, using radiocarbon measurements at the Centre for Isotopic Research on Cultural and Environmental Heritage (CIRCE). All measured modern samples were in agreement with the Southern Hemisphere (SH) 14C bomb-spike curve. Observed preliminary results indicate a decrease in the growth rate of the sapele tree (∼350 yr old) in the industrial period compared to the pre-industrial era. Growth rates for trees of the other 2 species were higher than sapele, with ayous being the fastest-growing species.
