The plant vigor defined in the laboratory may not indicate the final quality of seedlings produced under nursery conditions, or even their survival in plantations. So, we evaluated the influence of the storage conditions of Torresea acreana seeds on its emergence, as well as, on the morphological quality of produced seedlings. Seeds were collected in October/2011, packed, transported, conditioned in closed glas pots and stored in three environments for a period of 462 days. The treatments consisted of seedlings produced from seeds: 1 - without storage (control), 2 - stored in a dry chamber, 3 - stored in a humid chamber, and 4 - stored in an uncontrolled environment (laboratory). Sowing was performed in 50 cm³ plastic tubes filled with decomposed pine bark and coconut fiber (50/50 v/v) which were packed in a glasshouse. The study analyzed the percentage of emergence, mean seedlings emergence time, stem diameter, total height, ratio between total height and stem diameter, shoot length, mean root length, total dry biomass, root dry biomass, shoot dry biomass, and Dickson quality index. Seed storage proved to be a negative factor for the emergence and vigor of T. acreana seedlings. The vigor of the seeds is a preponderant factor to increase the morphological quality of the seedlings. |

In three landscape windows representing different uses of the Amazon forest, soil macrofauna
was sampled at 16 points displayed every 200m on a regular grid. At each of the 48 points we
measured macroinvertebrate abundance and species richness in 15 Orders and assessed soil
macro aggregation. Landscape composition and structure were quantified by analysing landscape
maps with the FRAGSTAT programme. Significant co inertia was observed among landscape
variables and species richness in groups. Ants and Coleoptera showed increased species
richness in deforested and highly fragmented areas whereas termites and most litter dwelling
arthropods (Myriapoda, Isopoda) exhibited opposite patterns. Another significant co inercia
was observed among macro invertebrate communities and soil aggregation. This suggests
that changes in landscape affect soil structure and functions associated to this attribute through
changes in macroinvertebrate communities. |
