Diverse urban plantings managed with sufficient resource availability can increase plant productivity and arthropod diversity

Buildings structures and surfaces are explicitly being used to grow plants, and these "urban plantings" are generally designed for aesthetic value. Urban plantings also have the potential to contribute significant "ecological values" by increasing urban habitat for animals such as arthropods and by increasing plant productivity. In this study, we evaluated how the provision of these additional ecological values is affected by plant species richness; the availability of essential resources for plants, such as water, light, space; and soil characteristics. We sampled 33 plantings located on the exterior of three buildings in the urban center of Brisbane, Australia (subtropical climatic region) over 2, 6 week sampling periods characterized by different temperature and rainfall conditions. Plant cover was estimated as a surrogate for productivity as destructive sampling of biomass was not possible. We measured weekly light levels (photosynthetically active radiation), plant CO2 assimilation, soil CO2 efflux, and arthropod diversity. Differences in plant cover were best explained by a three-way interaction of plant species richness, management water regime and sampling period. As the richness of plant species increased in a planter, productivity and total arthropod richness also increased significantly likely due to greater habitat heterogeneity and quality. Overall we found urban plantings can provide additional ecological values if essential resources are maintained within a planter such as water, light and soil temperature. Diverse urban plantings that are managed with these principles in mind can contribute to the attraction of diverse arthropod communities, and lead to increased plant productivity within a dense urban context.

Potenciais aves dispersoras de sementes das espécies vegetais zoocóricas da Mata da Bica, Botucatu - SP

The semidecidual forests, as tropical forests, presents zoochoric dispersal syndrome in the most of their plant species, with approximately one third of frugivorous species responsible for the seeds dispersal are birds. The bills width is a limiting factor, it must be equal or bigger than the seeds width, because the viable seeds dispersal depends on leaving the digestive system after been swallowed hole. Birds and plants inventorys were realized in a semidecidual Forest fragment, in Botucatu – SP, called Mata da Bica. After this, the birds consumers of fuits/seeds were selected (frugivorous, granivorous and onivorous) and also the zoochoric plants, both for building a possibilities matrix, to verify the potential seed dispersers according to the seeds and bills width. Going to the matrix end we can observe a decrease in the interaction possibillities, because the seeds width increases and the bills width decreases. It has been observed that 50,7% seeds could be dispersed by all listed birds, because the seeds were narrower than the narrowest bill. In the other way large seeded species, as Holocalix balansae and Hymemaea courbaril has shown only two possible dispersers: Trogon surrucura and Piaya cayana. There are no possible dispersers to Syagrus oleraceae in the matrix. The need for large birds or other animals that works as large seed disperses demand conservation efforts, since most of these animals need big and conserved areas for their life habits
