Numerosas cultivares de feijão de procedências diversas são plantadas na microrregião Alto Purus - Acre havendo, entretanto, predominância bem acentuada da cultivar "Rosinha" que representa quase 90% da população de Phaseolus. Apesar de perfeitamente adaptada às condições de solo e clima do Estado e de sua elevada capacidade de produção, esta cultivar é altamente susceptível à "Mela" ou Murcha da Teia Micélica" (Thanatephorus cucumeris (Frank Donk.), principal fator limitante do desenvolvimento da cultura do Estado. De um modo geral, todas as cultivares plantadas na região são susceptíveis a esta enfermidade sendo sua produtividade variável. Quando as condições climáticas são favoráveis à enfermidade, o ataque é severo e perdas totais podem ocorrer no...

A pecuária bovina é a atividade do setor primário de maior importância econômica no Acre. Atualmente, o estado possui o quarto maior rebanho bovino da Região Norte, estimado em aproximadamente 2,6 milhões de cabeças, criado em uma área superior a 1,5 milhão de hectares de pastagens cultivadas. Assim como no restante da Região Amazônica, as pastagens cultivadas representam a base de sustentação da atividade pecuária no Estado do Acre, fornecendo forragem de qualidade e em quantidade suficiente para a alimentação do rebanho na maior parte do ano. É graças a esta característica que a pecuária de corte do Acre apresenta um dos maiores índices de rentabilidade do País. A avaliação e seleção de novas cultivares de gramíneas e leguminosas forrageiras, adaptadas...

"Lebonnet", nova recomendação para a orizicultura acreana.

CAMPOS, I. S.; MEDEIROS, J. A..

A cultivar "Lebonnet", que hora se recomenda para cultivo nas condições de sequeiro favorecido no Acre, apresentou rendimentos em torno de 3.000 kg/ha, em plantios não adubados, tanto em campos experimentais como em áreas de produtores. Este material, se plantado conforme as recomendações técnicas para seu cultivo, poderá preencher, em parte, os requisitos da orizicultura acreana pois, além de apresentar resistência ao acamamento e tolerância às doenças atualmente prevalescentes na região, sua excelente qualidade de grão proporciona elevado valor comercial.

O estado do Acre, que até pouco tempo concentrava sua economia na atividade extrativista, caminha para a diversificação do setor primário, destacando-se a pecuária pelo crescimento da bovinocultura de corte e de leite, resultante da corrida de investidores de outros centros e de incentivos governamentais a essa atividade. Os processos de exploração dessa atividade na região apoiam-se, predominantemente, nas pastagens cultivadas, constituídas de Colonião (Panicum maximum), Jaraguá (Hyparrhenia rufa) e Brachiaria decumbens. O desenvolvimento da pecuária ressaltou a necessidade de substituição dos processos tradicionais de exploração por outros mais racionais; compreendendo a formação de pastagens com forrageiras adaptadas, produtivas, rústicas e de elevado...

Por ser uma fruteira de clima tropical, o abacaxizeiro apresenta melhor crescimento e qualidade dos frutos quando cultivado em faixas de temperatura que vão de 22 °C a 32 °C, mais especificamente entre 29 °C e 32 °C, o que está de acordo com as temperaturas médias anuais do estado. A cultura é exigente em luz, necessitando, anualmente, de uma insolação entre 2.500 e 3.000 horas, ou seja, 6,8 a 8,2 horas de brilho solar por dia. A planta não tolera sombreamento. Sabendo-se que as fases críticas para a cultura concentram-se no período de crescimento vegetativo e floração e considerando que o déficit hídrico pode afetar a produção e, consequentemente, o peso e a qualidade do fruto, faz-se necessário o uso de irrigação nos meses de menor precipitação.

Acclimation of the marine diatom Pseudo‐nitzschia australis to different salinity conditions: effects on growth, photosynthetic activity and domoic acid content

Mechanisms of biochemical adaptation of sea organisms to environmental stresses.

Ayache, Nour; Hervé, Fabienne; Lundholm, Nina; Amzil, Zouher; Caruana, Amandine.

oxic Pseudo‐nitzschia australis strains isolated from French coastal waters were studied to investigate their capacity to adapt to different salinities. Their acclimation to different salinity conditions (10, 20, 30, 35 and 40) was studied on growth, photosynthetic capacity, cell biovolume and domoic acid (DA) content. The strains showed ability to acclimate to a salinity range from 20 to 40, with optimal growth rates between salinities 30 and 40. The highest cell biovolume was observed at the lowest salinity 20 and was associated with the lowest growth rate. Salinity did not affect the photosynthetic activity; Fv/Fm values and the pigment contents remained high with no significant difference among salinities. An enhanced production of zeaxanthin was,...

Phylogénie moléculaire des huîtres du genre Crassostrea. Approche par les techniques de restriction enzymatique et de séquençage

Kavousi, Javid.

Climate change refugia and adaptation are two important mechanisms by which species may survive ongoing climate change (Moritz et al., 2013). However, how these two mechanisms interact is poorly understood. The goal of this paper is to explore their interaction, focusing specifically on ocean acidification refugia.

Variations des activites digestives en fonction des facteurs du milieu chez les crustaces

Delandes, Hélène.

En France, ainsi que dans de nombreux autres pays, l'histoire de l'ostréiculture est émaillée d'une succession de phases de développement, de surexploitation et d'apparition de maladies qui perturbent lourdement la profession. Depuis la disparition massive de l'huître portugaise, Crassostrea angulata, victime entre 1969 et 1971 d'une épidémie virale et l'effondrement de l'élevage de l'huître plate Ostrea edulis dû à deux parasitoses, la marteiliose et la bonamiose, l'ostréiculture française connaît actuellement une situation de monoculture de l'huître creuse japonaise Crassostrea gigas, suite à l'introduction de l'espèce entre 1971 et 1975 (Grizel & al. 1991). Pour tenter de remédier à cette situation de monoculture, qui reste une des inquiétudes...

Physiological and Metabolic Responses of Freshwater and Brackish-Water Strains of Microcystis aeruginosa Acclimated to a Salinity Gradient: Insight into Salt Tolerance

Galgani, Francois; Benyamin, Y; Vanworhmoudt, A; Cecaldi, J.

Proteolytic enzymes of hepatopancreas of six species of peneids (Penaeus kerathurus, P. japonicus, P. monodon, P. stylirostris, P. merguiensis and P. vannamei ) have been studied. Some of their physiological variations have been characterised. Increase in acclimation temperature of crustaceans enhances increase of specific activities of proteases. Variations of salinity does not modify specific activities, nor quantities of trypsin, nor electrophoretic patterns of these different proteases.

Proliferation of microcystin (MC)-producing Microcystis aeruginosa in brackish waters has been described in several locations and represents a new concern for public and environmental health. While the impact of a sudden salinity increase on M. aeruginosa physiology has been studied, less is known about the mechanisms involved in salt tolerance after acclimation. This study aims to compare the physiological responses of two strains of M. aeruginosa (PCC 7820 and PCC 7806), which were isolated from contrasted environments, to increasing salinities. After acclimation, growth and MC production rates were determined and metabolomic analyses were conducted. For both strains, salinity decreased the biovolume, growth, and MC production rates and induced the...

Photosynthetic responses of four tropical tree species grown under gap and understorey conditions in a semi-deciduous forest

Rev. Bras. Bot.

Souza,Gustavo M.; Sato,Agnaldo M.; Ribeiro,Rafael V.; Prado,Carlos Henrique B. A..

Leaf CO2 assimilation (A) as a function of photosynthetic photon flux density (Q) or intercellular CO2 concentration (Ci) and chlorophyll fluorescence measurements were carried out on four tropical woody species growing in forest gap and understorey (Bauhinia forficata Link. and Guazuma ulmifolia Lam. as pioneers, and Hymenaea courbaril L. and Esenbeckia leiocarpa Engl. as non-pioneers). Chlorophyll fluorescence indicated similar acclimation capacities of photochemical apparatus to contrasting light environments irrespective to plant species. Maximum CO2 assimilation and quantum yield derived from A/Q curves indicated higher photosynthetic capacity in pioneer than in non-pioneer species in forest gap. However, the differences among species did not show a...

In the present study we have investigated the effects of heat acclimation on brain and hepatic Hsp70 protein levels and body temperature of broiler chickens in response to gradual heat stress. Two groups of broilers were raised up to 47 days of age under distinct temperature conditions: thermoneutral (TN, according to bird age) or hot environmental (HS, 31-33°C). At 46 days of age, the birds reared at high ambient temperature were transferred to thermoneutrality conditions. After 18 h, these birds and the birds reared at thermoneutral temperature were submitted to gradual heat stress in a climatic chamber so that environment temperature was increased from 28 to 40ºC at a rate of 2ºC/h. Colonic temperature was measured using a thermometer sensor probe at...

Temperature as an environmental factor has been a frequent subject of study, since it affects either directly or indirectly all living organisms. The determination of thermal limits (critical thermal minima - CTmin and maxima - CTmax) for the tropical ornamental freshwater teleost Xiphophorus maculatus Günther, 1866 (platyfish) was performed after their acclimation to the following temperatures: 15, 20, 25, and 30ºC, for seven days. After this period, the water temperature was elevated or reduced at a rate of 0.125ºC/min until CTmax and CTmin could be determined as the temperature at which 50% of the animals had lost equilibrium. Mean values for CTmax and CTmin for the acclimation temperatures of 15, 20, 25, and 30ºC were respectively:...

ABSTRACT In the Amazon region, agroforestry systems (AFSs) are recommended as a sustainable production alternative for local communities. A common component in Amazonian AFSs are tropical fruit trees, which can form the canopy or grow in the understory. In this study, we evaluated the effect of high radiation on photosynthesis, growth and seedling survival of four Amazonian fruit-tree species: Theobroma cacao, Eugenia stipitata, Inga edulis and Psidium guajava. Growth, chlorophyll fluorescence, gas exchange, and leaf pigments were measured in seedlings of each species grown for 12 months inside shade houses with low (8%), medium (30%) and high relative illumination (100%). Eugenia stipitata and T. cacao had the lowest acclimation capacity to high solar...

This work describes, analyzes and compares the wood anatomy of Alseis pickelii from two distinct sites in Tropical Dry Forest. One site is an exploited forest that was disturbed by deforestation whereas the other site is preserved and has not been logged since selective logging in the 1960's. For the evaluation of wood anatomy, plant material was processed following standard techniques for light microscopy and histochemical tests. The results indicated that A. pickelii did not vary qualitatively between the two sites. The histochemical tests indicated the presence of prismatic crystals and starch in radial parenchyma of samples from both sites. Some quantitative parameters differed significantly between the two sites including: vessel frequency; vessel...
