Data from: Plant functional types broadly describe water use strategies in the Caatinga, a seasonally dry tropical forest in northeast Brazil

Cynthia Wright, André Lima, Eduardo Souza, Jason West & Bradford Wilcox
In seasonally dry tropical forests, plant functional type can be classified as deciduous low wood density, deciduous high wood density, or evergreen high wood density species. While deciduousness is often associated with drought-avoidance and low wood density is often associated with tissue water storage, the degree to which these functional types may correspond to diverging and unique water use strategies has not been extensively tested. We examined (1) tolerance to water stress, measured by pre-dawn...

Data from: Adaptations and responses of the common dandelion to low atmospheric pressure in high altitude environments

Carla Arce, Zoe Bont, Ricardo Machado, Paulo Cristaldo & Matthias Erb
Atmospheric pressure is an important, yet understudied factor that may shape plant ecology and evolution. By growing plants under controlled conditions at different experimental stations in the Swiss alps, we evaluated the impact of ecologically realistic atmospheric pressures between 660 and 950 hPa on the growth and defence of different dandelion populations. Low atmospheric pressure was associated with reduced root growth and defensive sesquiterpene lactone production. Defence suppression only occurred in populations originating from lower...

Foraging networks and social tolerance in a cooperatively breeding primate (Callithrix jacchus)

María Fernanda De La Fuente, Cédric Sueur, Paul Garber, Júlio César Bicca-Marques, Antonio Souto & Nicola Schiel
Within-group competition over food resources can be a major cost of social living. In the wild, foragers are confronted with social (e.g. hierarchical rank) and ecological (e.g. food availability and distribution) challenges that affect their foraging decisions and feeding success. Exhibiting prosocial behaviors, such as tolerance at feeding sites, can benefit group members by developing affiliative social relationships, enhancing access to resources and maximizing fitness. We examined social tolerance at feeding sites in Callithrix jacchus,...

Data from: Phenology and wood density of plants growing in the semi-arid region of northeastern Brazil

Fernanda Galvão, André Lima, Clemir Oliveira, Valdemir Silva & Maria Rodal
The current knowledge about the influence of plant traits and climatic seasonality on the phenology of tropical rain forest plants is insufficient to understand how functional traits can explain mechanisms associated with phenological responses. We hypothesized that the density of the wood and the water stored in stem and root determine presence of phenological groups of trees. Leaf shedding, flushing, and flowering of high wood density species are related to rainfall, due to their low...

Disentangling leaf morphology in Daustinia montana (Convolvulaceae)

Juliana Alencar, André Luiz Borba Do Nascimento, Paulo Duarte-Neto & Maria Teresa Buril
Daustinia montana (Convolvulaceae) is the only species of the genus, and is notable for its wide leaf variability. To understand whether this plasticity is correlated with the distribution of the species, linear morphometric and leaf contour analyses were performed. Specimens from herbaria were photographed, and pre-established linear measurements were made. A multivariate analysis was then performed to test the strength of associations among morphological characteristics, climatic variables, and distribution of the species. Elliptic Fourier analysis...
