Grouping organisms may suffer reduced growth due to food deprivation in the presence of
larger conspecifics, but this cost can be outweighed by advantages of reduced predation risk …

The coral-reef damselfish Dascyllus marginatus forms social groups of up to 25 individuals
per coral. The fish forage for drifting zooplankton while remaining close to their home coral …

Animals in social aggregations often spend more time foraging than solitary conspecifics.
This may be a product of the relative safety afforded by aggregations: group members can …

We estimated the population consequences to an inferior competitor from interactions with a
superior competitor that also is an indirect mutualist. The competitors are two damselfishes …

Individual adults of three Caribbean damselfishes defend feeding areas that do not overlap
with those of conspecific adults. The feeding areas of adults of the two smaller species …

The more ecologists examine the role of trait‐mediated indirect interactions (TMIIs),
especially in regulating predator–prey interactions, the more we recognize their fundamental …

Costs and benefits to group living in animals may affect the fitness of individual group
members and also demography of the population. The effects of grouping on the growth …

The supply of larvae is a major determinant of population and community structure in coral
reef fishes. However, spatial and temporal variation in condition (ie quality) of potential …

Consumer effects on prey are well known for cascading through food webs and producing
dramatic top-down effects on community structure and ecosystem function. Bottom-up effects …

Species that shelter in a biogenic habitat can influence their refugia and, in turn, play an
essential role in shaping local patterns of biodiversity. Here we explore a positive feedback …
