ABSTRACT.- Aim: The intensification of livestock systems generates structural and functional changes in native grassland, which alter their capacity to respond to disturbances. Our objective was to evaluate the resilience to an extraordinary consecutive-droughts event, across an intensification gradient of livestock systems. Our prediction was that sites with more intensive management (less diverse) will have lower resilience (as resistance and/or recovery) to drought. Location: South-central
region of Uruguay. Conclusion: Our research supports the insurance hypothesis by demonstrating that farms with greater biodiversity (less intensive management) have higher resistance to drought. We found that species richness is not enough to account for the effect of diversity on resilience. Our results emphasize the importance of preserving grassland biodiversity to maintain resilient ecosystems in the face of climate change. © 2023 International Association for Vegetation Science. |

Nowadays, there is a great interest in using lignocellulosic materials as substrate for the production of
biorefi nery products. Eucalypti are good options to use as crops to obtain different kinds of biofuels and
derivatives, since their plantations show high adaptation potential to soil and weather conditions in Uruguay.
The basic process steps involved in the obtainment of biorefi nery materials are: pretreatment, hydrolysis,
fermentation and products separation. As delignifi cation is an important process to obtain biorefi nery products,
in this context the evaluation of the biological (BT) and hydrothermal (TT) pretreatment of different species of
Eucaliptus was studied. The possibility of obtaining sugars, alcohols and organic acids was the main focus.
The results of these investigations show a good production of reducing sugars (4?5 mg/mL for both BT and
TT pretreatments), acetic acid (3?8 mg/mL for BT and 3?7 mg/mL for TT) and isopropanol (18?48 mg/mL for
BT and 20?30 mg/mL for TT). In conclusion, the results show similar behaviours for BT and TT pretreatments,
which is a quite important result since BT is cheaper and cleaner and thus a more attractive technology. |
