The objective of this study was to determine the maximum depth, structure, diameter and
biomass of the roots of common woody species in two savanna physiognomies (savanna
woodland and open woody savanna) in Brazil?s Pantanal wetland. The root systems of 37
trees and 34 shrubs of 15 savanna species were excavated to measure their length and
depth and estimate the total root biomass through allometric relationships with stem
diameter at ground level. In general, statistical regression models between root weight and
stem diameter at ground level showed a significance of P < 0.05 and R2 values close to or
above 0.8. The average depths of the root system in wetland savanna woodland and open
woody savanna are 0.8 ± 0.3 m and 0.7 ± 0.2 m, respectively, and differ from the root
systems of savanna woody species in non-flooding areas, whose depth usually ranges from
3 to 19 m.Weattribute this difference to the adaptation of woody plant to the shallow water
table, particularly during the wet season. This singularity of woody species in wetland
savannas is important when considering biomass and carbon stocks for national and global
carbon inventories. |

This study was carried out to evaluate the nutritive value of elephant grass (Pennisetum purpureum, Schum.) silages with the addition of 0, 4, 8, 12 and 16% dehydrated mango (Mangifera indica, L.) by-product (DMB), on the fresh matter basis. A randomized complete design with four replications was used. As experimental silos, 210L plastic drums were used. Dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose (HCEL), ether extract (EE), total carbohydrates (TC), non-fibrous carbohydrates (NFC), neutral detergent insoluble nitrogen (NDIN, % total N), acid detergent insoluble nitrogen (ADIN, % total N), pH values, ammoniacal nitrogen (% total N), lactic acid, acetic acid, butyric acid and propionic acid levels were determined. The DM, OM, CP, EE, NFC, NDIN, lactic acid and propionic acid levels increased with the DMB addition while the NDF, ADF, hemicellulose, N-NH3/ammoniacal nitrogen levels and the pH values decreased with the DMB addition. The addition of DMB had a quadratic effect on the acetic and butyric acid levels but there was no effect with the addition of DMB on TC and ADIN. The DMB can be used at the ensiling of the elephant grass, because the addition of 8.6% improves the silages fermentative process. However, these silages have low crude protein levels and high contents of ether extract and nitrogen compounds mixed with the fiber (NDIN and ADIN) in the silages, that may damage their use by animals.
