Diversos parametros fenotipicos foram avaliados em 40 estirpes de Bradyrhizobium que nodulam a soja, incluindo 31 que foram ou sao utilizadas em estudos e/ou inoculantes brasileiros e nove estirpes representativas das especies B. japonicum, B. elkanii e do genotipo misto. Os parametros fenotipicos incluiram analises in vitro (morfologia das colonias, sorogrupo, resistencia a niveis baixos e elevados de antibioticos, sintese de acido indol acetico e expressao da hidrogenase) e analises in vivo (toxidez causada em soja e alfafa pela producao de rizobiotoxina e restricao da nodulacao pelo alelo Rj4 da cultivar Hill). A analise conjunta desses parametros permitiu o agrupamento filogenetico das estirpes. A SEMIA 586 e sua variante natural SEMIA 0580 foram as unicas estirpes agrupadas com as representativas da especie B. japonicum. A maioria dos isolados do Cerrado se localizou no genotipo misto. Outros isolados do Cerrado e as demais estirpes utilizadas em estudos e /ou inoculantes brasileiros ficaram agrupadas com a especie B. elkanii. |

We investigated carbon and nitrogen stable isotope ratios and radiocarbon concentration of
soil macrofauna (termites and eathworms) obtained from the Lamto reserve in Ivory Coast. Two
different vegetations were selected: a gallery forest along the Bandama river and a grass savanna
dominated by Hyparrhenia and Andropogon. Three replicated plots were set in each vegetation.
Termites and earthworms were sampled by hand-sorting. The isotope ratios of soils, leaf-litter
and grass were determined and compared with the fauna.
Noditermes aburiensis and Euchilotermes tensus, which are abundant soil-feeding termites in
the gallery forest, had the highest values in both carbon and nitrogen isotope ratios within the
gallery forest. Several species in the subfamily Termitinae and soldierless termites (the subfamily
Apicotermitinae) had the ?elta-13C and ?elta-15N values lower than N. aburiensis and E. tensu.
Cephalotermes rectangularis, Termes hospes and Amitermes evuncifer were plotted in the ?elta-
13C and ?elta-15N region, which is so-called a wood/soil interface feeder. Microcerotemes
pauvus and other wood-feeding termites had the lowest ?elta-13C and ?elta-15N values. In
contrast, Trinervitermes geminatus was the least enriched in nitrogen isotope ratio at the grass
savanna.
Epigeic species of Dichogaster had the lowest delta-15N and ?elta-13C values at both
vegetation. Milsonia anomala, which is a common mesohumic endogeic earthworm in Lamto,
had higher delta-15N values than epigeic species of Dichogaster. Delta-15N values in endogeic
eudrilid worms were still higher, and they were the highest in the gallery forest. In total,
categorization by the isotope ratios (Tayasu 1998) was in good agreement with the ecological
categorization.
Agastrodrilus opisthogynus, which has been sampled only in the grass savanna, had the highest
delta-15N values in the grass savanna. Hyodo et al. (in press) have found that there is a good
correlation between delta-15N and capital-delta-14C values. The fact suggests that termites
and earthworms which consume more decomposed materials (?humification gradient? indicated
by delta-15N; Tayasu et al. 1997) utilized ?aged? carbon indicated by capital-delta-14C. However,
capital-delta-14C values in A. opisthogynus did not show the same trend, instead, the higher
delta-15N values were considered to be caused by the trophic enrichment. Our results confirmed
the hypothesis that Agastrodrilus opisthogynus is predatory (Lavelle, 1983).
