Ant species identity mediates reproductive traits and allocation in an ant-garden bromeliad.
BACKGROUND AND AIMS Determining the sources of variation in floral morphology is crucial to understanding the mechanisms underlying Angiosperm evolution. The selection of floral and reproductive traits is influenced by the plant's abiotic environment, florivores and pollinators. However, evidence that variations in floral traits result from mutualistic interactions with insects other than polli...
متن کاملAnts mediate the structure of phytotelm communities in an ant-garden bromeliad.
The main theories explaining the biological diversity of rain forests often confer a limited understanding of the contribution of interspecific interactions to the observed patterns. We show how two-species mutualisms can affect much larger segments of the invertebrate community in tropical rain forests. Aechmea mertensii (Bromeliaceae) is both a phytotelm (plant-held water) and an ant-garden e...
متن کاملSpecies-Specific Effects of Ant Inhabitants on Bromeliad Nutrition.
Predator activities may lead to the accumulation of nutrients in specific areas of terrestrial habitats where they dispose of prey carcasses. In their feeding sites, predators may increase nutrient availability in the soil and favor plant nutrition and growth. However, the translocation of nutrients from one habitat to another may depend on predator identity and diet, as well as on the amount o...
متن کاملSpecies traits and environmental characteristics together regulate ant‐associated biodiversity
Host-associated organisms (e.g., parasites, commensals, and mutualists) may rely on their hosts for only a portion of their life cycle. The life-history traits and physiology of hosts are well-known determinants of the biodiversity of their associated organisms. The environmental context may strongly influence this interaction, but the relative roles of host traits and the environment are poorl...
متن کاملTask Allocation in Ant Colonies
In this paper we propose a mathematical model for studying the phenomenon of division of labor in ant colonies. Inside this model we investigate how simple task allocation mechanisms can be used to achieve an optimal division of labor. We believe the proposed model captures the essential biological features of division of labor in ant colonies and is general enough to study a variety of differe...
