Microbes often display cooperative behavior in which individual cells put in work and sacrifice resources to collectively ...

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 ...

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 a previous paper in this series a model was proposed for the competition between plant populations with different rooting depths. This model predicts that in mixtures of plant populations with ...

In many species, mating comes at the steep price of an organism's life, an evolutionary process intended to regulate reproductive competition. But males of certain roundworm species have doubled down ...

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 ...

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 ...
