The costs and benefits of kleptoparasitism in frigatebirds: An integrative review
Kleptoparasitism is a foraging strategy that involves stealing food from other animals. Frigatebirds are seabirds that are known to engage in kleptoparasitism, especially on other nesting seabirds such as boobies and tropicbirds.

Sublethal effects of kleptoparasitism on experimental social spider colonies
A defining feature of parasitism is the harm parasites cause to their host via a reduction in lifetime reproductive success. Harm, also referred to as “virulence,” may involve host mortality or sublethal effects, such as a decreased body condition or ...

Scrounging by foragers can resolve the paradox of enrichment [PDF]
Theoretical models of predator–prey systems predict that sufficient enrichment of prey can generate large amplitude limit cycles, paradoxically causing a high risk of extinction (the paradox of enrichment).

Modeling potential effects of brown bear kleptoparasitism on the predation rate of Eurasian lynx
Kleptoparasitism is a frequent phenomenon when consumption of prey by predator continues for a relatively long period. This is common when prey is larger or of a similar size as the predator.

Kleptoparasitic Hawk-Dove Games
The Hawk-Dove game is a classical game-theoretical model of potentially aggressive animal conflicts. In this paper, we apply game theory to a population of foraging animals that may engage in stealing food from one another. We assume that the population is composed of two types of individuals, Hawks and Doves.

Nest material kleptoparasitism occurs when an individual steals material from another individual's nest. Here we document 69 observations of grey herons, Ardea cinerea, removing nest material from the nests of monk parakeets, Myiopsitta monachus.

A continuous ideal free distribution approach to the dynamics of selfish, cooperative and kleptoparasitic populations [PDF]
Population distributions depend upon the aggregate behavioural responses of individuals to a range of environmental factors. We extend a model of ideally motivated populations to describe the local and regional consequences of interactions between three ...

Kleptoparasitism and Phoresy in the Diptera
Spiders, dung-feeding scarabs, social, and prey-storing insects provide predictable and concentrated sources of food for a variety of thief flies (kleptoparasites) and their larvae. Whenever waiting in the vicinity of the "host" for an opportunity to exploit its resources is more energy efficient and less dangerous than foraging among hosts, a number ...

Golden jackal as a new kleptoparasite for Eurasian lynx in Europe
The arrival of a new carnivore can have important effects on local communities. While several effects of introduced alien species have been well documented, few studies have reported the ecological consequences of an expanding native species.

Spiders in a hostile world (Arachnoidea, Araneae)
Spiders are powerful predators, but the threats confronting them are numerous. A survey is presented of the many different arthropods which waylay spiders in various ways. Some food-specialists among spiders feed exclusively on spiders.
