| Guilds of Aculeate solitary wasps and bees that nest in preexisting cavities in wood are important components of terrestrial ecosystems because they engage in several ecological interactions (e.g. predation and pollination) with other species of plants and animals. Spatial and temporal variations in richness and abundance of solitary wasps and bees can be related to changes in environmental structure and in the diversity of other groups of organisms. The nesting period of these Aculeata is their most critical life cycle stage. Females of solitary wasp and bee species invest relatively more time constructing and provisioning their nests than do females of social species. Differently from species that nest in the soil or construct exposed nests, the main... |

| This paper reviews recent knowledge about the functional roles that herbivores have in intertidal communities in Chile. Specifically, I review field and laboratory studies dealing with the food preferences of herbivores, the responses of algae to herbivore attacks and reports of negative and positive functional effects of herbivores on algal populations and communities. Most herbivores studied are characterized as generalist species. Green ephemeral and a few corticated algae dominate diets, while all species considered ingest larvae and post-metamorphic stages of invertebrates challenging classical characterizations of the herbivore guild. Functional redundancy and complementarity within the herbivore guild is discussed in relation to both quantitative... |
