Machine Learning Data Imputation and Prediction of Foraging Group Size in a Kleptoparasitic Spider
Mathematics, 2021 Cost–benefit analysis is widely used to elucidate the association between foraging group size and resource size. Despite advances in the development of theoretical frameworks, however, the empirical systems used for testing are hindered by the vagaries ...

Kleptoparasitic Hawk-Dove Games
SPORA: A Journal of Biomathematics, 2021 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.

Frontiers in Ecology and Evolution, 2015 Ceropegia species (Apocynaceae) have deceptive pitfall flowers and exploit small flies as pollinators, supposedly by chemical mimicry. Only preliminary data on the composition of flower scents are available for a single species so far, and the mimicry ...

Kleptoparasitism and Phoresy in the Diptera
The Florida Entomologist, 1999 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 ...

Spiders in a hostile world (Arachnoidea, Araneae)
Arachnologische Mitteilungen, 2011 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.

Host-plant relationships of gall-inducing Thysanoptera – the lack of patterns [PDF]
Journal of Insect Biodiversity and Systematics, 2020 Adult Thysanoptera occur within plant galls for various reasons and use of the term “gall-thrips” without defining the particular relationship is uninformative and misleading.

Caching reduces kleptoparasitism in a solitary, large felid [PDF]
Journal of Animal Ecology, 2017 Summary Food caching is a common strategy used by a diversity of animals, including carnivores, to store and/or secure food. Despite its prevalence, the drivers of caching behaviour, and its impacts on individuals, remain poorly understood, particularly for short‐term food cachers.

Cicadas "dig wells" that are used by ants, wasps and beetles
European Journal of Entomology, 2007 There is a high density of the cicada Cryptotympana facialis (Walker) (Hemiptera: Cicadidae) in urban parks in central Japan during summer. This cicada uses its stylet to pierce holes in the trunks of keyaki trees, Zelkova serrata and then feeds on the ...
