Some observations on the reproductive biology of the scuttle fly Megaselia andrenae (Diptera: Phoridae) at the nesting site of its host Andrena agilissima (Hymenoptera: Andrenidae)

European Journal of Entomology, 2004
Some behavioural aspects of the reproductive biology of Megaselia andrenae Disney, a kleptoparasite of the communal bee Andrena agilissima (Scopoli), were investigated at the nesting site of its host at Isola d'Elba (Italy).

Estimating large carnivore populations in an arid fenced reserve using spatial capture–recapture modelling

Wildlife Biology, EarlyView.
In fenced protected areas where large carnivore populations persist or have been restored through reintroduction, population monitoring is essential to inform management. Robust density estimates are particularly important given the strong influence of large carnivores on ecosystem processes, yet such data remain scarce for arid systems where ...

Foraging Patterns of Non-Territorial Eastern Imperial Eagle (Aquila heliaca): A Case of Successful Adaptation

Diversity, 2022
The Optimal Foraging Theory predicts that, to maximize fitness, animals adapt their foraging strategy that provides the most benefit for the lowest cost, maximizing the net energy gained.

Between‐species contagion drives HPAI transmission and mass mortality in seabirds

Journal of Animal Ecology, Volume 95, Issue 8, Page 1488-1503, August 2026.
Modelling the unprecedented avian panzootic caused by High‐Pathogenicity Avian Influenza (HPAI) across the Northeast Atlantic gannet breeding metapopulation, we estimated 28% (95% CI: 21%–34%) HPAI‐related mortality. Large‐scale outbreak initiation was best explained by external infection sources, most likely, other seabird species.

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.

Kleptoparasitism in Arcotheres exiguus (Burger, 1895): Symbiotic Dynamics and Reproductive Implications in Paphia malabarica from the Southwest Coast of India

International Journal of Bio-resource and Stress Management
The present study conducted from April to September, 2024 along the southwest coast of Maharashtra, India, to investigate the host–symbiont relationship between the pinnotherid pea crab Arcotheres exiguus and its bivalve host Paphia malabarica ...

Matching Theories on Kleptoparasitism to a Complex Avian Event in Perth, Western Australia

Journal of the Royal Society of Western Australia, 2021
Theories on kleptoparasitism are matched to a complex event during which a Laughing Dove Streptopelia senegalensis was injured by a car, probably fatally, then depredated by a group of Australian Magpies Gymnorhina tibicen and subsequently ...

Tree Climbing in African Lions and Leopards

African Journal of Ecology, Volume 64, Issue 6, August 2026.
ABSTRACT Tree climbing has been documented in most felids, but patterns, correlates, and possible functions of this behaviour are not well documented for all species, including the African lion. Using a comparative behavioural ecology approach and drawing on opportunistic field observations from multiple sites in northern Tanzania, I used Bayesian ...

Amphotis marginata (Coleoptera: Nitidulidae) a highwayman of the ant Lasius fuliginosus. [PDF]

PLoS ONE, 2017
The space occupied by evolutionarily advanced ant societies can be subdivided into functional sites, such as broodchambers; peripheral nest chambers; kitchen middens; and foraging routes.

A review on true dung beetles' evolutionary and ecological responses to temperature and impacts on ecosystem functions

Ecological Entomology, Volume 51, Issue 4, Page 621-638, August 2026.
True dung beetles are a speciose group of ecosystem engineers that play key roles as detritivores in natural and agricultural landscapes. Scarabaeine beetles show strong thermal plasticity and there is increasing evidence of rapid evolutionary divergence in response to temperature across ecological and evolutionary timescales, with likely consequences ...
