Long-term consequences of agonistic interactions between socially naive juvenile American lobsters (Homarus americanus).
Agonistic behavior of decapod crustaceans occurs in the wild, is highly stereotypical, and is readily quantifiable. Here we explore the persistence of dominance relationships in socially naı̈ve juvenile American lobsters (Homarus americanus) by examining the time frame over which behavior changes as a result of previous fight experience. We paired opponents for three fights: initial; 1 hour late...
متن کاملSource and specificity of chemical cues mediating shelter preference of Caribbean spiny lobsters (Panulirus argus).
Caribbean spiny lobsters display a diversity of social behaviors, one of the most prevalent of which is gregarious diurnal sheltering. Previous research has demonstrated that shelter selection is chemically mediated, but the source of release and the identity of the aggregation signal are unknown. In this study, we investigated the source and specificity of the aggregation signal in Caribbean s...
متن کاملThe Mechanisms and Consequences of Interspecific Competition Among Plants
During the past 100 years, studies spanning thousands of taxa across almost all biomes have demonstrated that competition has powerful negative effects on the performance of individuals and can affect the composition of plant communities, the evolution of traits, and the functioning of whole ecosystems. In this review, we highlight new and important developments that have the potential to great...
متن کاملIntraspecific competition in the ant Camponotus
The mechanisms of competition and resource domination were analysed in the Mediterranean ant Camponotus cruentatus. In a plot located in southern Spain mature colonies are overdispersed, which is indicative of territoriality in other species. Unexpectedly, however, workers from neighbouring colonies commonly foraged in areas that overlapped by more than 44%. This suggests that while mature colo...
متن کاملPollution by conspecifics as a component of intraspecific competition among Aedes aegypti larvae
1. The role of pollution by conspecifics in the costs associated with larval intraspecific competition was investigated for Aedes aegypti (Diptera: Culicidae). 2. The growth of larval A. aegypti mosquitoes reared in clean water and water in which another larva had previously grown was compared; this procedure eliminates interactions through food consumption between competitors and allows the ef...
