DENDROMETRIC CHARACTERISTICS AND BASIC WOOD DENSITY OF EUCALYPTUS CLONES IN DIFFERENT SPACING

This study aimed to analyze the effect of two planting spacing on dendrometric characteristics and basic wood density of eucalyptus clones. The experiment in the municipality of Jataí-GO, Brazil, used a randomized complete block design with three replications, in which the spacing (3.0 m x 2.0 m and 3.0 m x 3.0 m) were allocated to the plots and the clones (3335, 3336 and 3487) in the subplots. Diameter at breast height (dbh), total height (HT), total volume (VT), basic density (db), stem biomass (BS), leaf and branch biomass (BLB) and total biomass (BT) were evaluated. The data were submitted to analysis of variance, followed by the Tukey test for comparison of means at the 5% probability level. It was found that the dbh and VT characteristics were not influenced by the planting spacing nor by the clone types. The HT was influenced by the spacing with the highest value (26.3 m) verified in the spacing 3 m x 3 m. The db was influenced only by the clone types and the clones 3335 and 3487 presented the highest values (0.46 and 0.41 g.cm-3, respectively). The BS, BLB and BT were influenced only by clones with higher yields with clones 3335 and 3487. There were no significant interactions for any of the evaluated characteristics

INFLUÊNCIA DE VARIÁVEIS METEREOLÓGICAS NO CRESCIMENTO EM DIÂMETRO E ALTURA DE Schizolobium parahyba var. amazonicum

Objetivou-se avaliar o efeito da influência de variáveis meteorológicas no crescimento em diâmetro e em altura de paricá (Schizolobium parahyba var. amazonicum) por meio da análise de correlação de Pearson. Foram empregados dados de parcelas permanentes mensuradas do 6º ao 10º ano de idade de um plantio no espaçamento 3 x 3 m localizado em Alta Floresta, MT. Foram calculados, para o período de crescimento avaliado, os incrementos correntes médios, em diâmetro a 1,30 m de altura do solo (dap) e em altura total, os quais foram correlacionados com as variáveis meteorológicas precipitação (Pp), umidade relativa do ar (UR) e velocidade do vento (Vv). Verificou-se que, à exceção da correlação entre o dap e a velocidade do vento, todas as correlações foram significativas. A UR apresentou correlação negativa tanto para incremento em dap quanto para incremento em altura enquanto a Vv apresentou correlação negativa com o incremento em dap. Para as demais variáveis, as correlações foram positivas, apresentando relação diretamente proporcional entre as variáveis meteorológicas e os incrementos em dap e em altura das árvores de paricá

Height, volume and form factor equations for Tectona grandis L.f. in Alta Floresta (MT)

Studies on allometric models are essential for quantifying the potential of a stand, especially when the objective is to know the wood stock through estimates. This study aimed to select height, volume and artificial form factor equations for a teak stand with data from a sample with 81 trees at 96 months in different diameter classes. The correlation analysis was performed between the variables total height, diameter with and without bark at 1.30 m soil height (dbhcc and dbhsc), total volume with and without bark (VTcc and VTsc) and artificial form factor with and without bark (ffcc and ffsc), using the Pearson coefficient. Six models were evaluated for each category: height, volume and artificial form factor, which were selected by the following criteria: analysis of variance, adjusted coefficient of determination, standard error of estimate, Akaike information criterion and graphical analysis of residues. The selected equations were validated by applying the L & O test. The variables dbhcc, dbhsc, HT, VTcc and VTsc presented significant correlations, ranging from moderate to very strong, the others presented weak correlation. The model that presented the best relation of total height to diameter was the model of Azevedo and contributors. For the total volume with and without bark, Schumacher and Hall model in its logarithmic form was the one that presented the best results. The adjusted models for artificial form factor did not present satisfactory results and, therefore, the use of average form factor is recommended. The mean form factor values by diameter class ranged from 0.4498 to 0.7139 and 0.4480 to 0.7075 for diameter with and without bark, respectively

Biomassa e carbono em um povoamento de teca em Mato Grosso

Este estudo teve o objetivo de quantificar a biomassa e o carbono e avaliar modelos matemáticos para estimativas de biomassa de diferentes compartimentos da parte aérea de árvores de teca de um plantio, aos 72 meses de idade, localizado no munícipio de Cotriguaçu no Estado de Mato Grosso. Foram selecionadas aleatoriamente 30 árvores distribuídas em diferentes classes de diâmetro e de altura. Em cada árvore-amostra mediram-se o diâmetro a 1,30 m de altura do solo (dap), a altura total (HT) e procedeu-se a quantificação do volume (V) por meio da cubagem rigorosa. As árvores foram abatidas, separadas e identificadas nos compartimentos fuste, folhas e galhos além de serem retirados discos para a determinação da densidade básica da madeira. Foram determinadas a biomassa de cada compartimento e estimado o carbono considerando um teor médio de 43,15% da biomassa. A relação entre as variáveis dap, HT, V e a biomassa para fuste, galhos, folhas e parte aérea total foi avaliada pelo coeficiente de Pearson e os modelos de Husch e de Kopezky-Gerhardt foram ajustados para estimativa da biomassa. Verificou-se que a biomassa presente em cada compartimento seguiu o padrão fuste > galhos > folhas e ocorreu predominância de correlação forte e muito forte entre as variáveis dap, HT, V e a biomassa. As equações oriundas do modelo de Husch foram as que apresentaram melhores ajustes

Development of digestive organs of female broilers under varying post-hatch fasting times

This study aimed to evaluate the effect of post-hatch fasting time on the weights of body and digestive organs of chicks. Fertile eggs from 62-week-old broiler breeders (Cobb Fast lineage) were incubated and, after hatching, female chicks were randomly divided into six treatments, which corresponded to fasting periods (0, 6, 12, 24, 48, and 72 hours), with 40 chicks per treatment. At 01, 03, 06, and 10 days after hatching, measurements of body weight; residual yolk weight; relative weights of proventriculus + gizzard, intestine + pancreas and liver; and intestine total length were made. At 6 days of age, the chicks submitted to post-hatch fasting, for up to 12 hours, demonstrated greater development, with body weights higher than the other birds. Yet, when fed, no compensatory gain was observed and, at 10 days of age, the birds submitted to 48- and 72-h fasting remained with a lower body development. Intestine growth was also compromised by post-hatch fasting, being reduced in both weight and length. A post-hatching fasting of up to 24 hours did not interfere with the weights of body and digestive organs of 10-day-old female broiler chickens. However, 48- and 72-h post-hatch fastings affected adversely the weight and growth of digestive organs in the birds

Reemergence of human malaria in Atlantic Forest of Rio Grande do Sul, Brazil

Unforeseen Plasmodium infections in the Atlantic Forest of Brazilian Extra-Amazonian region could jeopardise malaria elimination. A human malaria case was registered in Três Forquilhas, in the Atlantic Forest biome of Rio Grande do Sul, after a 45 years’ time-lapsed without any malaria autochthonous notification in this southern Brazilian state. This finding represents the expansion of the malaria distribution areas in Brazil and the southernmost human malaria case record in South America in this decade. The coexistence of the bromeliad-breeding vector Anopheles (Kerteszia) cruzii and non-human primates in the Atlantic Forest regularly visited by the patient claimed for the zoonotic origin of this infection. The reemergence of Atlantic Forest human malaria in Rio Grande do Sul was also discussed
