Resumo: | Flood and fire can harm plants but they can have survival strategies, such as the seed bank. We aimed to determine the influence of fire and flood on the richness, abundance and diversity of the seed bank. Sampling was carried out in October/2013, year of prolonged drought, and October/2014, year of a heavy flood, in ten areas along the Paraguay River. The areas were selected in satellite images, five with old burn (2010, three years before sampling) and five with recent burn (2013, three months before sampling). In each area, we marked a 20 m long transect with ten 20 × 20 cm quadrats where we collected 5 cm deep topsoil samples, five with and five without litter. Seed bank richness and abundance were determined by seedling emergence. Old burn areas presented greater abundance than recent burn. The drier year presented greater abundance, richness and diversity than flood year. Removal of litter reduced the richness only in the wetter year. There was no difference in richness in the drier year. The removal of the litter did not affect the abundance and diversity. Interaction between fire and flood did not affect richness, abundance and diversity of the seed bank. |

Pretendemos determinar a influência de fogo e inundação na riqueza, abundância e diversidade do banco de sementes. Realizamos amostragens em um ano mais seco (outubro/2013) e em um de maior inundação (outubro/2014), em dez áreas ao longo do rio Paraguai. Selecionamos 5 áreas com históricos de fogo antigo (2010, 4 anos antes da amostragem) e 5 recente (2013, 1 ano antes da amostragem). Nas áreas, marcamos transectos de 20 m, nos quais coletamos 10 amostras de solo (20 × 20 × 5 cm), cinco com e cinco sem serrapilheira. Composição e abundância do banco de sementes foram estimadas por meio de emergência de plântulas. Áreas de fogo antigo apresentaram maior abundância que áreas de fogo recente. O ano de seca apresentou maiores abundância e riqueza do que o de inundação. A remoção da serrapilheira reduziu a riqueza no ano de inundação. Não houve diferença em riqueza no ano seco. A abundância nas amostras com e sem serrapilheira foram similares. A interação entre fogo e inundação não afetou a abundancia, riqueza e diversidade do banco de sementes.Universidade Federal de Mato Grosso do Sul (UFMS), Inst.

Flood and fire can harm plants but they can have survival strategies, such as the seed bank. We aimed to determine the influence of fire and flood on the richness, abundance and diversity of the seed bank. Sampling was carried out in October/2013, year of prolonged drought, and October/2014, year of a heavy flood, in ten areas along the Paraguay River. The areas were selected in satellite images, five with old burn (2010, three years before sampling) and five with recent burn (2013, three months before sampling). In each area, we marked a 20 m long transect with ten 20 × 20 cm quadrats where we collected 5 cm deep topsoil samples, five with and five without litter. Seed bank richness and abundance were determined by seedling emergence. Old burn areas presented greater abundance than recent burn. The drier year presented greater abundance, richness and diversity than flood year. Removal of litter reduced the richness only in the wetter year. There was no difference in richness in the drier year. The removal of the litter did not affect the abundance and diversity. Interaction between fire and flood did not affect richness, abundance and diversity of the seed bank. |
