Individuals rarely have equal competitive abilities, with body size being one of the most important attributes affecting the mechanism (i.e. exploitative and interference) and consequences of ...
When an individual directly alters the resource-attaining behavior of other individuals, the interaction is considered interference competition. For example, when a male gorilla prohibits other males ...
We examine how interspecific competition and two types of size-selective predation affect population density, variability and persistence in laboratory cultures of two species of Daphnia, D. magna and ...
Wild-type zebrafish consistently beat out genetically modified Glofish in competition for female mates, an advantage that led to the disappearance of the transgene from the fish population over time, ...
In ecology, competition is defined as a type of negative interaction that occurs when resources are in short supply. Intraspecific competition occurs when individuals of the same species compete for ...
Penguins are arguably the most iconic and well-loved of the handful of animal species that call Antarctica home. From a scientist's point of view, they are also important ecosystem indicators: how ...
William Muir examines a tank of transgenic Glofish. The fish express a fluorescent protein cloned from sea anemones. (Purdue Agricultural Communication photo/Tom Campbell) The study, the first to ...
