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. |

Brazil in eucalyptus nurseries in the Bahia State in 2007, which made it necessary, in 2015, to import through the Quarantine Laboratory ?Costa Lima?, Embrapa Meio Ambiente of Jaguariúna, Sao Paulo, Brazil, the exotic control bioagent, Selitrichodes neseri (Hymenoptera: Eulophidae) from the University of Pretoria in Pretoria, South Africa. This introduction was requested by FCA/UNESP-Botucatu Campus (University of São Paulo State, Faculty of Agrarian Sciences) and by the PROTEF/IPEF (Programa Cooperativo em Proteção Florestal/Instituto de Pesquisas e Estudos Florestais/IPEF). Seedlings of hybrid clones of Eucalyptus grandis x Eucalyptus camaldulensis were planted in 1.7 L pots with soil sterilized with a mixture of soil-sand-manure (1:1:1) and irrigated daily to obtain the parasitoid galls. These seedlings were kept in an open nursery at FCA/UNESP and infested, naturally, by L. invasa. Approximately seventy days after the infestation, the plants with galls were taken to Embrapa and offered to parasitism to multiply S. neseri in the laboratory. The production of S. neseri adults was 3,020 in 2015, 8,616 in 2016/2017 and 4,700 in 2018; which were sent to UNESP and then to forestry companies associated to PROTEF for releasing in Eucalyptus plantations. |
