A novel type of nutritional ant-plant interaction: ant partners of carnivorous pitcher plants prevent nutrient export by dipteran pitcher infauna. [PDF]
PLoS ONE, 2013 Many plants combat herbivore and pathogen attack indirectly by attracting predators of their herbivores. Here we describe a novel type of insect-plant interaction where a carnivorous plant uses such an indirect defence to prevent nutrient loss to ...

A Kleptoparasitic Cecidomyiid and Other Flies Associated With Spiders
Psyche: A Journal of Entomology, 1980 Spiders and their webs are predictable sources of insect cadavers. A small number of animals regularly exploit this resource, either as kleptoparasites or commensals, depending on whether symbionts compete for the same prey (see Robinson and Robinson ...

A ‘crying wolf’ game of interspecific kleptoparasitic mutualism [PDF]
Biology Letters, 2014 We model a potentially mutualistic interaction between a species making antipredator alarm calls and a species which eavesdrops on those calls. Callers may or may not make deceptive alarm calls in order to kleptoparasitize food from eavesdroppers, which in turn may either heed or ignore all alarm calls.

New Results From the Pre‐Pottery Neolithic Site of Al Uyaynah, Tabuk, in Northwestern Saudi Arabia
Arabian Archaeology and Epigraphy, EarlyView.ABSTRACT Al Uyaynah is a low sandstone mound on an alluvial plain, long known for its extensive surface remains of stone‐built circular and rectangular structures. Following test excavations in 2012, more detailed excavation was undertaken in 2016 within one of the largest rectangular stone structures.

Taxonomic and functional diversity of urban bees of the world
Conservation Biology, EarlyView.Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Trans‐oceanic migration and wind utilization by Amur Falcons (Falco amurensis)
Ibis, EarlyView.The Amur Falcon Falco amurensis performs one of the world's longest raptor migrations, involving a non‐stop crossing of the Indian Ocean of approximately 2800 km. While the existence of this route is known, the mechanistic details of wind exploitation and seasonal navigation remain to be fully elucidated.

A game theoretical model of kleptoparasitism with incomplete information [PDF]
Journal of Mathematical Biology, 2009 Kleptoparasitism, the stealing of food from one animal by another, is a common natural phenomenon that has been modelled mathematically in a number of ways. The handling process of food items can take some time and the value of such items can vary depending upon how much handling an item has received.
