Evolutionary history of Neotropical savannas geographically concentrates species, phylogenetic and functional diversity of lizards

Supporting information (scripts) to compute diversity and endemism indices copied and available by Dan Rosauer (https ://github.com/DanRosauer/phylospatial). Aim: Understanding where and why species diversity is geographically concentrated remains a challenge in biogeography and macroevolution. This is true for the Cerrado, the most biodiverse tropical savanna in the world, which has experienced profound biodiversity loss. Previous studies have focused on a single metric (species composition), neglecting the fact that ‘species’ within the biome are often composed...

Optimal Defense Theory in an ant‐plant mutualism: extrafloral nectar as an induced defense is maximized in the most valuable plant structures

Eduardo Calixto, Denise Lange, Judith Bronstein, Helena Torezan-Silingardi & Kleber Del-Claro
Optimal Defense Theory (ODT) predicts that to maximize the benefits of defense against herbivores while minimizing its costs, plants will invest in defenses to structures according to their value and to the likelihood that they will be attacked. Constitutive defenses are expected in structures of high value, whereas induced defenses are expected in structures of low value. Regarding the biotic defense mediated by extrafloral nectaries (EFNs) and based on ODT, we predicted that under control...

Climate seasonality drives ant-plant-herbivore interactions via plant phenology in an extrafloral nectary-bearing plant community

Eduardo Calixto, Letícia Novaes, Danilo Santos, Denise Lange, Xoaquín Moreira & Kleber Del-Claro
Interactions between ants and plants bearing extrafloral nectaries (EFNs) are among the most common mutualisms in Neotropical regions. Plants secrete extrafloral nectar, a carbohydrate-rich food that attracts ants, which in return protect plants against herbivores. This ant-plant mutualism is subjected to temporal variation, in which abiotic factors can drive the establishment and frequency of such mutualistic interaction. However, studies investigating how abiotic factors (e.g., climate) directly and indirectly influence ant-plant-herbivore interactions are incipient. In this...

Net benefits of a mutualism: influence of the quality of extrafloral nectar on the colony fitness of a mutualistic ant

Eduardo Calixto, Denise Lange & Kleber Del-Claro
Aim: Extrafloral nectar, a carbohydrate-rich liquid, is the main plant-based resource offered in exchange for ant protection. The positive results of this protection provided by ants are widely studied and supported; however, studies showing the benefits that ants and their colonies have from the resources offered by plants such as extrafloral nectar are scarce. Here, we evaluated how extrafloral nectar and artificial food resources with different nutrient concentration benefit short- and long-term Camponotus crassus colony...
