Functional assembly of tropical montane tree islands in the Atlantic Forest is shaped by stress-tolerance, bamboo-presence and facilitation

Tina Christmann, Bruno H.P. Rosado, Guillaume Delhaye, ILAINE MATOS, Helena Roland, Yan Moraes, Julia Drummond & Imma Oliveras
Aims: Amidst the Campos de Altitude (Highland Grasslands) in the Brazilian Atlantic Forest, woody communities grow either clustered in tree islands or interspersed within the herbaceous matrix. The functional ecology, diversity and biotic processes shaping these plant communities are largely unstudied. We characterised the functional assembly and diversity of these tropical montane woody communities and investigated how they fit within Grime’s CSR (C – competitor, S – stress-tolerant, R – ruderal) scheme, what functional trade-offs...

Assessing the importance of reproductive modes for the evaluation of altitudinal distribution patterns in tropical frogs

Carla Siqueira, Davor Vrcibradic, Mauricio Almeida-Gomes & Carlos Frederico Rocha
Altitudinal patterns in species richness vary among taxa and are shaped by the intrinsic traits of different organisms and their response to environmental variables. We evaluated the relationship between anuran richness and elevation along local and regional altitudinal gradients within the Brazilian Atlantic Forest based on data from fieldwork (local dataset; 100-1,900 m a.s.l.) and on compiled secondary information (regional dataset; 0-2,300 m a.s.l.). We also tested whether frog distribution patterns were consistent with the...

Amazonian rainforests once thought to hold an innate pristine wilderness, are increasingly known to have been densely inhabited by populations showing a diverse and complex cultural background prior to European arrival. To what extent these societies impacted their landscape is unclear. Amazonian Dark Earths (ADEs) are fertile soils found throughout the Amazon Basin, created by pre-Columbian societies as a result of more sedentary habits. Much is known of the chemistry of these soils, yet their...

Mode of maternal provisioning in the fish genus Phalloceros: a variation on the theme of matrotrophy

Eugenia Zandona, Maja Kajin, Paulo Buckup, Jeferson Amaral, Igor Souto-Santos & David Reznick
The placenta is a complex organ that shows high morphological diversity. Among fish, the first vertebrates that have evolved a placenta, the family Poeciliidae exhibits very diverse modes of maternal provisioning even among congeneric species. Here, we investigated the embryonic growth curve across seven recently-described species of the highly diverse genus Phalloceros (Eigenmann, 1907). We also investigated possible intraspecific differences and whether other female characteristics affected embryo mass. We found that embryo mass decreased until...
