Tree diversity and composition in Amazonia are known to be strongly determined by the water supplied by precipitation. Nevertheless, within the same climatic regime, water availability is modulated by local topography and soil characteristics (hereafter referred to as local hydrological conditions), varying from saturated and poorly drained to well-drained and potentially dry areas. While these conditions may be expected to influence species distribution, the impacts of local hydrological conditions on tree diversity and composition remain poorly understood at the whole Amazon basin scale. Using a dataset of 443 1-ha non-flooded forest plots distributed across the basin, we investigate how local hydrological conditions influence 1) tree alpha diversity, 2) the community-weighted wood density mean (CWM-wd) – a proxy for hydraulic resistance and 3) tree species composition. We find that the effect of local hydrological conditions on tree diversity depends on climate, being more evident in wetter forests, where diversity increases towards locations with well-drained soils. CWM-wd increased towards better drained soils in Southern and Western Amazonia. Tree species composition changed along local soil hydrological gradients in Central-Eastern, Western and Southern Amazonia, and those changes were correlated with changes in the mean wood density of plots. Our results suggest that local hydrological gradients filter species, influencing the diversity and composition of Amazonian forests. Overall, this study shows that the effect of local hydrological conditions is pervasive, extending over wide Amazonian regions, and reinforces the importance of accounting for local topography and hydrology to better understand the likely response and resilience of forests to increased frequency of extreme climate events and rising temperatures.

Context. Although beef consumption has been linked to increased blood cholesterol, it has positive impacts on human health and provides essential nutrients of high biological value. Aims. This study investigated the effects of aging time on beef quality, the chemical composition of the Longissimus thoracis (LT) muscle, and the metabolite and fatty acid profile of the subcutaneous fat from young bulls finished in feedlot with a high-lipid diet. Methods. Fifty young bulls were divided into groups following their breed composition, Nellore (n = 25) and Angus × Nellore crossbred (n = 25), and com randomly assigned into four pens. The feedlot phase consisted of 105 days of feed, and the diet (80% concentrate) was formulated to meet or safely exceed the requirements of beef cattle to achieve an average daily gain of 1.6 kg/day. After slaughter, meat samples were collected between the 11th and 13th ribs 24 h postmortem. Steaks were aged for 1, 14, 28, and 42 days. Key results. No differences were observed for total weight loss, drip loss, and cooking loss between the genetic groups (P > 0.05). An increase in lipid oxidation was observed for TBARS in the LT beef and subcutaneous fat (P < 0.01). Shear force was influenced by breed and aging time (P < 0.01). There was a significant interaction between aging time and the parameters L* a*, b* c*, and h* (P < 0.01). The crossbred animals had greater (P < 0.01) concentrations of collagen, and Nellore had greater (P < 0.01) concentration of moisture in their LT beef. In total, 33 metabolites were identified in beef extract, and differences were observed in beef from both groups. Nellore animals had higher concentrations of polyunsaturated fatty acids and conjugated linoleic acid. Conclusions. The shear force, collagen concentration, and moisture were affected by breeds, while the aging time affected lipid oxidation, shear force, and colour parameters. Different breeds and a high-lipid diet modified the metabolite profile of meat and the profile of subcutaneous fat. Implications. These findings suggest that genetic manipulation could potentially be used to improve beef quality. MenosContext.

520 $aContext. Although beef consumption has been linked to increased blood cholesterol, it has positive impacts on human health and provides essential nutrients of high biological value. Aims. This study investigated the effects of aging time on beef quality, the chemical composition of the Longissimus thoracis (LT) muscle, and the metabolite and fatty acid profile of the subcutaneous fat from young bulls finished in feedlot with a high-lipid diet. Methods. Fifty young bulls were divided into groups following their breed composition, Nellore (n = 25) and Angus × Nellore crossbred (n = 25), and com randomly assigned into four pens. The feedlot phase consisted of 105 days of feed, and the diet (80% concentrate) was formulated to meet or safely exceed the requirements of beef cattle to achieve an average daily gain of 1.6 kg/day. After slaughter, meat samples were collected between the 11th and 13th ribs 24 h postmortem. Steaks were aged for 1, 14, 28, and 42 days. Key results. No differences were observed for total weight loss, drip loss, and cooking loss between the genetic groups (P > 0.05). An increase in lipid oxidation was observed for TBARS in the LT beef and subcutaneous fat (P < 0.01). Shear force was influenced by breed and aging time (P < 0.01). There was a significant interaction between aging time and the parameters L* a*, b* c*, and h* (P < 0.01). The crossbred animals had greater (P < 0.01) concentrations of collagen, and Nellore had greater (P < 0.01) concentration of moisture in their LT beef. In total, 33 metabolites were identified in beef extract, and differences were observed in beef from both groups. Nellore animals had higher concentrations of polyunsaturated fatty acids and conjugated linoleic acid. Conclusions. The shear force, collagen concentration, and moisture were affected by breeds, while the aging time affected lipid oxidation, shear force, and colour parameters. Different breeds and a high-lipid diet modified the metabolite profile of meat and the profile of subcutaneous fat. Implications. These findings suggest that genetic manipulation could potentially be used to improve beef quality.
