Conteúdo:  There is a consensus about negative impacts of droughts in Amazonia. Yet, extreme wet episodes, which are becoming as severe and frequent as droughts, are overlooked and their impacts remain poorly understood. Moreover, drought reports are mostly based on forests over a deep water table (DWT), which may be particularly sensitive to dry conditions. Based on demographic responses of 30 abundant tree species over the past two decades, in this study we analyzed the impacts of severe droughts but also of concurrent extreme wet periods, and how topographic affiliation (to shallow - SWTs - or deep - DWTs - water tables), together with species functional traits, mediated climate effects on trees. Dry and wet extremes decreased growth and increased tree mortality, but interactions of these climatic anomalies had the highest and most positive impact, mitigating the simple negative effects. Despite being more drought-tolerant, species in DWT forests were more negatively affected than hydraulically vulnerable species in SWT forests. Interaction of wet-dry extremes and SWT depth modulated tree responses to climate, providing buffers to droughts in Amazonia. As extreme wet periods are projected to increase and at least 36% of the Amazon comprises SWT forests, our results highlight the importance of considering these factors in order to improve our knowledge about forest resilience to climate change.

Título:  Physicochemical properties and sensory evaluation of meat from feedlot lambs fed with wet brewery waste.

Conteúdo:  Abstract Sheep meat presents variations in qualitative characteristics that influence consumer preference. These characteristics are influenced by ante-mortem factors, such as sex, breed, age at slaughter and feeding; and post-mortem factors, such as meat cooling and storage time and temperature. Twenty-four uncastrated Suffolk lambs were housed in individual corrals and received one of four treatments consisting of four levels of replacement of sorghum silage with wet brewery waste (WBW; 0; 33; 66 and 100% replacement). The diets were isoproteic and contained 18.8% crude protein. The weight and fat proportion in the carcass increased linearly (p≤0.05) while the muscle proportion decreased linearly (p≤0.05) as the WBW levels were increased in the diets. The proximate composition of the meat was not significantly influenced by the WBW levels (P>0.05), except for the ash content which increased linearly (p=0.0003). There was no influence (p>0.05) of the use of WBW on pH, cooking losses and lambs? meat texture profile. Shear force decreased linearly (p≤0.05). Regarding the meat color, lightness (L*) and redness (a*) were not influenced by the inclusion of WBW. Yellowness (b*) increased linearly (p=0.0038). Regarding the attributes related to lambs? sensory analysis, there was no effect (p> 0.05) of the inclusion of WBW in the diets. The use of WBW as bulky food replacing sorghum silage in confined feedlot lambs diet allows the main physical-chemical characteri... Mostrar Tudo
