Abstract:
This aim of this study was to evaluate the lignification in young stems of the Lophanthera lactescens Ducke plant grown in vitro L. lactescens (Malpighiaceae), a species endemic in the Brazilian Amazon that possesses both medicinal properties and could be used in the forest product industry. Plants grown in vitro condition in MS medium were analyzed using Infrared (IR) microspectroscopy in a diffuse reflectance mode, fluorescence microscopy. Moreover, histochemical tests such as the Wiesner and Maüle test were run to monitor the process of lignification in cell walls. The spectra of IR microscopy recorded using cross section tissue are representative of guaiacyl/syringyl lignin, based on the 1336 and 1246 cm-1 signal. Individuals presenting stem sprains, resulting from the marked development, produced gelatinous fibers with a clear cellulose layer. Initially, fluorescence microscopy demonstrated lignin deposition in the cell corner region having progressive deposition in the secondary wall of tracheary elements of the stem.

Avaliou-se a durabilidade natural da madeira de cinco essências arbóreas: Eucalyptus citriodora Hook, Gliricidia sepium (Jacq.) Steud, Lophantera lactescens Ducke, Piptadenia gonoacantha (Mart.) Macbr. e Samanea saman (Jacq.) Merr. O ensaio de campo foi realizado no campus da Universidade Federal Rural do Rio de Janeiro, de fevereiro de 2001 a novembro de 2002. Seis amostras de cada essência, parcialmente enterradas em posição vertical, foram dispostas aleatoriamente em cinco blocos. Em laboratório, segundo um sistema de notas relacionado ao estado fitossanitário da madeira, as amostras foram classificadas com um índice de comportamento, para cada essência, conforme seu aspecto fitossanitário. Também foram observados o estado da casca das amostras, a dureza da madeira e a presença de rachaduras longitudinais no corpo da amostra. As madeiras, mais e menos duráveis dentre os parâmetros avaliados, foram Laphantera lactescens e Piptadenia gonoacantha respectivamente. Em 47% das amostras que foram atacadas, três espécies de térmitas foram identificadas: Coptotermes havilandi, Nasutitermes jaraguae e Nasutitermes minor.

Abstract:
Measurements of CO2 and water vapor flux using eddy covariance are being made from a 40 m tower located in a transitional tropical forest near Sinop Mato Grosso. As complementary information to this study, the photosynthetic light response curves of three species located near the tower were measured at different heights in the forest canopy and light conditions with the objective of understanding seasonal and spatial (height in the forest canopy and gap or shade located plants) trends in the photosynthetic light response. The measurements were made in a canopy emergent tree (30 m tall) identified as Brosimum lactescens, and in two relatively short plants (0.6 to 1.6 m height) identified as Quiina pteridophylla and Diniszia excelsa located in different light condition. Measurements were made from the end of 2000 dry season to January 2002. These data suggest that species response to seasonal variations in rainfall are variable. In addition, shade plants have a higher quantum yield (A) and a lower estimated gross photosynthesis at saturating (photosynthetic active radiation - PAR) (Amax) than gap plants, presumably because shade plants are adapted to lower average light levels.

Abstract:
Em função de se analisar a produção, dinâmica e decomposição de serrapilheira em busca da sazonalidade do microclima em uma floresta tropical de transição Amazônia Cerrado, propõe-se estimar a produção de serrapilheira, por meio de caixas de coleta de 1 m² e o acúmulo de serrapilheira sobre o solo por meio de quadrantes de 25 x 25 cm, distribuídos aleatoriamente. Determinaram-se a constante de decaimento (K), o coeficiente de retorno de serrapilheira (K L) e a constante de decomposição (K'). Com o emprego de bolsas de nylon preenchidas com folhas de espécies de relevância na floresta (Tovomita schomburgkki e Brosimium lactescens) estudou-se a decomposição de folhas e se monitaram os fatores ambientais por meio de equipamentos instalados em uma torre micrometeorológica. A produção de serrapilheira não só se apresentou de forma sazonal, com significativa influência da umidade relativa do ar e da precipitação, em uma floresta de transição, mas foi majoritariamente composta de folhas seguidas de galhos e miscelânea (flores e frutos). A decomposição de folhas em florestas tropicais foi acelerada em ambas as estações, seca-úmida e úmida-seca, sendo a velocidade de decomposição das folhas maior na estação úmida-seca.

Abstract:
AbstractPrimates are important seed dispersers in natural ecosystems and agro-ecosystems, but the latter scenario remains under-studied. The degree to which primates favour plant regeneration greatly depends on post-dispersal processes. The main objective of this study was to compare patterns of seed/seedling fate and seedling recruitment in two habitats of the black howler monkey (Alouatta pigra Lawrence 1933), rustic cocoa and rain forest, and two types of seed-deposition locations, monkey latrines and control locations. Field experiments were carried out within the non-overlapping home ranges of six monkey groups, three in cocoa and three in forest. Seed and seedling fates were assessed for one focal tree species, Brosimum lactescens. The probabilities of seed survival (0.52), germination (0.72), seedling establishment (0.73) and early seedling survival (0.38) were not affected by habitat or seed-deposition location. Late seedling survival was similar in the two habitats but was higher in control locations (0.22) than in latrines (0.09). In cocoa, 4641 seedlings of 59 species were recorded, in forest 3280 seedlings of 68 species. Seedling recruitment was similar in both habitats, but latrines had higher densities than control locations. The importance of agro-ecosystems with low management intensity for the maintenance of ecological processes in anthropogenic landscapes is discussed.

"Pinus" (Pinaceae) e Inga marginata Wild "Inga" (Mimosaceae), submetidas ao processo de degradação em razão da exposição à intempérie no período de 12 meses, as madeiras foram colocadas em dois ambientes com características edafoclimáticas diferenciadas, isto é, foram montados dois campos de apodrecimento, sendo um dentro de uma mata secundária e outro a céu aberto, em um pasto formado por gramíneas rasteiras. Na avaliação, adotou-se um índice de deterioração médio, para expressar a degradação causada pelos fatores bióticos, nos corpos-de-prova oriundos de toras expostas nos respectivos ambientes. As determinações da densidade aparente, bem como da resistência à flexão (módulo de elasticidade (MOE) e ruptura (MOR)) e compressão paralela às fibras da madeira, foram realizadas antes e depois da exposição à intempérie. Os resultados indicaram que ocorreram reduções diferenciadas nas propriedades avaliadas. As diminuições significativas da densidade ocorreram somente nos corpos-de-prova oriundos das madeiras expostas dentro da mata, bem como as reduções nos módulos de elasticidade e ruptura foram mais acentuadas nas madeiras procedentes desse ambiente. A resistência à compressão da madeira apresentou-se com reduções maiores, também nesse ambiente.

Abstract:
In tropical moist forests, length of the dry period may have a profound influence on leaf dynamics, plant growth and survival. To evaluate the role of light and water availability on seedling performance, a 1-y experiment was carried out in a tropical moist forest in the Bolivian Amazon in which seedlings of three tree species (Brosimum lactescens, Cedrela odorata and Schizolobium amazonicum) were planted in gaps and the understorey. Variation in length of the dry period was simulated by subjecting part of the seedlings to a water treatment at the end of the dry period. Gaps and understorey had a similar soil moisture content, which varied between 39% in the wet season and 16% in the dry season. Height and leaf growth rates were higher in gap compared to understorey plants, and in the wet compared to the dry season. A high growth during the wet season provided gap plants with a decisive size advantage over understorey plants during the dry season. Their larger root system allowed gap plants to explore a larger surface area and deeper soil layers for water. Consequently, gap plants of Cedrela experienced a shorter deciduous period (22 d) compared to understorey plants (61 d). Watering at the end of the dry season cued the flushing of new leaves by Cedrela, although it did not lead to a higher plant growth.

Abstract:
The photosynthetic light response of Amazonian semi-deciduous forest trees of the rain forest–savanna transition near Sinop Mato Grosso, Brazil was measured between July 2000 and September 2003 to test the hypothesis that the photosynthetic capacity of trees acclimated to different growth light environments will decline during the dry season. Maximum photosynthesis (Amax) and stomatal conductance (gmax) were significantly higher during the wet season; however, the physiological response to drought was not a clear function of growth light environment. For some species, such as Psychotria sp. growing in the mid-canopy, internal leaf CO2 concentration (Ci) was >30% lower during the dry season suggesting that declines in Amax were caused in part by stomatal limitations to CO2 diffusion. For other species, such as Brosimum lactescens growing at the top of the canopy, Tovomita schomburgkii growing in the mid-canopy, and Dinizia excelsa growing in the understorey, dry season Ci declined by <20% suggesting that factors independent of CO2 diffusion were more important in limiting Amax. Dry-season declines in gmax appeared to be important for maintaining a more consistent leaf water potential for some species (T. schomburgkii and D. excelsa) but not others (Psychotria sp.). These results indicate that while seasonal drought exerts an important limitation on the physiological capacity of semi-deciduous Amazonian forest trees, the mechanism of this limitation may differ between species.

Abstract:
Este estudo foi desenvolvido numa área de floresta de transição Amazônia-Cerrado no norte de Mato Grosso. Teve como objetivo quantificar a dinâmica da produção e acúmulo e as partes constituintes da serrapilheira, bem como a participação das folhas no retorno do nitrogênio, fósforo e carbono ao solo por meio da decomposição. Foram coletados mensalmente durante um ano dados de serrapilheira total produzida, serrapilheira total acumulada no solo e avaliada a decomposição de folhas no período de seca e de chuvas. A produção de serrapilheira apresentou variações sazonais com maiores valores no período seco e predomínio da fração foliar durante todo o ano. Por outro lado, a serrapilheira acumulada não apresentou diferenças significativas entre o período de seca e o chuvoso como também correlação significativa com a serrapilheira produzida. A decomposição da serrapilheira exclusiva de folhas foi mais intensa no período chuvoso e em ordem decrescente de espécies, em T. schomburgkii, Thyrsodium sp, B. lactescens e P. sagotianum. A espécie P. sagotianum tanto no período seco quanto no chuvoso apresentou maior resistência à decomposição. O potencial de retorno de nitrogênio ao solo foi da ordem de 70,3 kg.ha-1.ano-1, para o fósforo, de 76,1 kg.ha-1.ano-1 e para o carbono, de 3,5 ton.ha-1.ano-1. Houve uma correlação entre a decomposição exclusiva de folhas e o retorno de nitrogênio e fósforo para todas as espécies estudadas no período de seca. No período chuvoso foi registrada correlação significativa somente para nitrogênio e o carbono para a espécie P. sagotianum.

Abstract:
The article presents the results of a scientific and production experiment to study the effect of a calcium-containing preparation on the indicators of multiple pregnancy, safety, lactescence, average daily gains of piglets on suckling. Studies have showed that the intramuscular injection of a calcium-containing preparation to lactating sows of the experimental group of the third parity immediately after the birth of the first piglet contributed to an increase in the safety of piglets by 3.5% compared to the control. The calculations showed that the greatest economic effect was obtained in the 2nd experimental group of sows, which after the birth of the first piglet, were injected intramuscularly with a calcium-containing preparation. Its cost was 2375 rubles for 1 sow.

Abstract:
Background: Chylothorax in cats represents a challenge due to the possibility of involvement of multiple etiologies and the harmful consequences resulting of the presence of the chylous effusion in the thorax. The causes include neoplasms in the thoracic cavity, heart disease and thoracic injuries. It is imperative that clinical nutritional and therapeutic and / or surgical management be immediate and directed to the treatment of the cause. The objective of this work was to report a case of idiopathic chylothorax in a domestic cat solved through surgical intervention and dietary maintenance applied.Case: A 4-year-old male cat, fed with diet for the age range of adult cats, was attended at the Veterinary Hospital of the Federal Rural University of Rio de Janeiro (HV - UFRRJ), with clinical complaint of difficulty breathing, inappetence, prostration and weight loss. In the clinical examination was verified intense tachypnea, presence of heart murmur, normocoratedmucosae, dehydration 7%. The animal was sedated to be submitted to radiographic examination of the thorax with pethidine and midazolam. Thoracic radiographs on the lateral, ventral-dorsal and orthostatic positions were realized and severe pleural effusion was observed in both hemitorax with drainage of 180 mL of lactescent fluid from the right hemithorax and 120 mL of left hemithorax liquid. Through analysis of cavity liquids the effusion was classified as chylous effusion. The hemogram showed a neutrophilic leukocytosis. Serum cholesterol and triglyceride concentrations (28 mg/dL and 43 mg/dL, respectively) were lower than the concentrations of the cavity liquid (67 mg/dL and 722 mg/dL, respectively).Ultrasound examination revealed no mass in the thoracic cavity and no changes in the pulmonary parenchyma. The echocardiographic examination was also performed and did not reveal any cardiac alterations. The initial treatment consisted of the clinical approach, through the exclusive alimentary management with low fat diet, in order to reduce toreduce the amount of chylous in the thorax. The rutine was administered at a dose of 250 mg/cat every 8 h orally. After 15 days, due to an unsatisfactory response to conservative treatment, surgical intervention was indicated. The technique used was pleural omentalization with block ligation of the thoracic duct without mesenteric lymphangiography together with pericardectomy and placement of the thoracic drain. During the postoperative period the animal remained under intensive care, with nasal oxygen therapy and intense analgesia during the first 72 h. After 20 days, the production of the chylous liquid was 2 mL/kg/ day, which made it possible to remove the drain. The cat received continuously with the exclusive diet of low fat to reduce the production of the chylous, without recurrence of chylous up to the present moment.Discussion: It is important to establish in a first approach of animals with chylous exudation the management of low-fat foods, along with appropriate pharmacological therapy, monitoring the patient in a constant and cautious way. If conservative clinical intervention is not satisfactory within 5 to 10 days, rapid surgical treatment is essential, due to the risk offibrosing pleuritis with consequent involvement of the pulmonary parenchyma, as occurred in this report. Duct ligation surgery and the pericardectomy was satisfactory for the resolution of the constant chylous production in the thorax of the animal, as well as the use of the low fat diet was essential to reduce the chylous effusion and fibrosing pleurisy, both the interventions made possible the maintenance of the patient’s health and well-being.Keywords: feline, cavitary fluid, quilting effusion, thoracic duct.

Abstract:
Este trabalho teve como objetivo avaliar a degradação natural de toras recém-abatidas em dois ambientes, bem como registrar a ocorrência de térmitas e coleobrocas nas respectivas toras e ambientes. As espécies utilizadas foram, Eucalyptus urophylla S T Blake, “eucalipto” (Myrtaceae), Melia azedarach L., “cinamomo” (Meliaceae), Lophantera lactescens Ducke, “lanterneira” (Malpighiaceae), Pinus elliottii Engelm, “pinus” (Pinaceae), Inga marginata Willd, “ingá” (Mimosaceae). O experimento foi realizado em dois campos de apodrecimento, um dentro de uma floresta secundária e outro num pasto de gramíneas. Adotou-se um sistema de classificação no qual, conforme o nível de deterioração da tora, notas foram atribuídas, fornecendo base para o cálculo do índice de deterioração. As coleobrocas e as térmitas foram coletadas e enviadas para identificação. Registraram-se 56,6% de toras com a presença de térmitas no campo de dentro da mata, sendo as espécies ocorrentes: Nasutitermes minor (HOLMGREN, 1906), Nasutitermes jaraguae (HOLMGREN, 1910) e Heterotermes longiceps (SNYDER, 1924). No campo a céu aberto, foram registrados 20% das toras com a presença de térmitas, de uma única espécie, H. longiceps. Tanto no campo de apodrecimento de dentro da mata como no que foi montado a céu aberto, as toras menos degradadas foram M. azedarach e L. lactescens.

Abstract:
O gênero Pradosia L. pertence à família Sapotaceae e está representado por 17 espécies no Brasil, com ocorrência também registrada para a Bahia (Carneiro et al., 2017), entretanto, devido a difícil delimitação de suas espécies, acredita-se que esse número não corresponde à realidade. Dentre as espécies que ocorrem no Semiárido nordestino, encontram-se Pradosia lactescens (Vell.) Radlk., Pradosia longipedicellata Alves-Araújo & M. Alves, Pradosia brevipes (Pierre) T.D. Penn., Pradosia kuhlmannii Toledo e Pradosia verrucosa Ducke, representadas por hábitos que variam de arbustos geófitos a árvores de dossel (Pennington, 1990). Alguns estudos de cunho ecológico, morfológico e molecular foram realizados para as espécies de Pradosia L., no entanto, não há relatos de estudos anatômicos que forneçam dados estruturais das suas partes vegetativas. Assim, estudos morfológicos minuciosos poderão ser úteis para a taxonomia do grupo.
