This study, conducted in central Portugal, shows that Eucalyptus globulus seeds are highly attractive to local fauna, including ants and rodents. Surprisingly, E. globulus seeds were as attractive as the exotic Acacia dealbata seeds and more attractive than the native Cistus salviifolius seeds. However, locations with negligible seed predation were abundant across the study area, which may help to explain the heterogeneous recruitment patterns of E. globulus seedlings found in previous studies.

If during a sunny day you spot the thousands of bright yellow flowering acacias on the coast of Portugal, then ask yourself who is spreading all of that pollen around! Even if the most common answer would be bees, when the acacia flowers it is still quite cold for them. This study highlights the so far neglected role of wind in acacia seed setting, arguing the influence this may have on acacia invasiveness and theories of pollination strategy evolution.

Ouratea spectabilis is a tree in the Brazilian savannas, or cerrados. Only a few specialized insects can produce the specific vibrations to liberate their pollen, in what is known as "buzz pollination". It is self-incompatible, and self-pollination reduced fertility to the level of interspecific crosses with co-generic species. Pollen viability was high, but in spite of pollen supplementation seed-to-ovule ratios were never over 30%, likely because of environmental stress.
