Data from: Allometric scaling laws linking biomass and rooting depth vary across ontogeny and functional groups in tropical dry forest lianas and trees

Chris M. Smith-Martin, Xiangtao Xu, David Medvigy, Stefan Schnitzer & Jennifer Powers
There are two theories about how allocation of metabolic products occurs. The allometric biomass partitioning theory (APT) suggests that all plants follow common allometric scaling rules. The optimal partitioning theory (OPT) predicts that plants allocate more biomass to the organ capturing the most limiting resource. We used whole-plant harvests of mature and juvenile tropical deciduous trees, evergreen trees, and lianas and model simulations to address the following knowledge gaps: 1) Do mature lianas comply with...

Data from: Genetic connectivity of Lionfish (Pterois volitans) in marine protected areas of the Gulf of Mexico and Caribbean Sea

Lionfish (Pterois volitans) have rapidly invaded the tropical Atlantic and spread across the wider Caribbean in a relatively short period of time. Because of its high invasion capacity, we used it as a model to identify the connectivity among nine marine protected areas (MPAs) situated in four countries in the Gulf of Mexico and the Caribbean Sea.This study provides evidence of local genetic differentiation of P. volitansin the Gulf of Mexico and the Caribbean Sea.A...

Liana abundance and diversity increase with rainfall seasonality along a precipitation gradient in Panama

Anthony Parolari & Stefan Schnitzer
In tropical regions, rainfall gradients often explain the abundance and distribution of plant species. For example, many tree and liana species adapted to seasonal drought are more abundant and diverse in seasonally-dry forests, characterized by long periods of seasonal water deficit. Mean annual precipitation (MAP) is commonly used to explain plant distributions across climate gradients. However, the relationship between MAP and plant distribution is often weak, raising the question of whether other seasonal precipitation patterns...

Data from: Connectivity explains local ant community structure in a Neotropical forest canopy: a large-scale experimental approach

Benjamin Adams, Stefan Schnitzer & Stephen Yanoviak
Understanding how habitat structure and resource availability affect local species distributions is a key goal of community ecology. Where habitats occur as a mosaic, variation in connectivity among patches influences both local species richness and composition, and connectivity is a key conservation concern in fragmented landscapes. Similarly, availability of limiting resources frequently determines species co-existence or exclusion. For primarily cursorial arthropods like ants, gaps between neighboring trees are a significant barrier to movement through the...
