Size matters: nest colonization patterns for twig-nesting ants
Understanding the drivers of ant diversity and co-occurrence in agroecosystems is fundamental because ants participate in interactions that influence agroecosystem processes. Multiple local and regional factors influence ant community assembly.We examined local factors that influence the structure of a twig-nesting ant community in a coffee system in Mexico using an experimental approach. We in...
متن کاملTwig-Nesting Ants: The Hidden Predators of the Coffee Berry Borer in Chiapas, Mexico
Coffee is a globally important crop that is subject to numerous pest problems, many of which are partially controlled by predatory ants. Yet several studies have proposed that these ecosystem services may be reduced where agricultural systems are more intensively managed. Here we investigate the predatory ability of twignesting ants on the main pest of coffee, the coffee berry borer (Hypothenem...
متن کاملLimitation of nesting resources for ants in Colombian forests and coffee plantations
1. This study examines limitation of nesting resources for leaf-litter and twig-nesting ants as a mechanism of diversity loss across an intensification gradient of coffee production in Colombia. Twelve farms were selected and classified into four management types: forest, polygeneric shade coffee, monogeneric shade coffee, and sun coffee (unshaded coffee monocultures). 2. At each of the farms, ...
متن کاملStrong influences of a dominant, ground-nesting ant on recruitment, and establishment of ant colonies and communities
Many factors drive the organization of communities including environmental factors, dispersal abilities, and competition. In particular, ant communities have high levels of interspecific competition and dominance that may affect community assembly processes. We used a combination of surveys and nest supplementation experiments to examine effects of a dominant ground-nesting ant (Pheidole synant...
متن کاملArboreal Ant Abundance and Leaf Miner Damage in Coffee Agroecosystems in Mexico
Shaded coffee agroecosystems traditionally have few pest problems potentially due to higher abundance and diversity of predators of herbivores. However, with coffee intensification (e.g., shade tree removal or pruning), some pest problems increase. For example, coffee leaf miner outbreaks have been linked to more intensive management and increased use of agrochemicals. Parasitic wasps control t...
