Predation bias of Ordovician predators on trilobites

Journal of the Geological Society, 2023
Although prey selection has been commonly documented in extant animals, evidence of prey selection in deep time is rare by comparison. Here, we collected 147 broken sclerites of trilobites, almost all of which were caused by lethal predation, from the Upper Ordovician in NW China.

Reciprocal intraguild predation and predator coexistence [PDF]

Ecology and Evolution, 2018
AbstractIntraguild predation is a mix of competition and predation and occurs when one species feeds on another species that uses similar resources. Theory predicts that intraguild predation hampers coexistence of species involved, but it is common in nature.

Geographical, temporal, and individual‐based differences in the trophic ecology of female Cape fur seals

Ecology and Evolution, 2023
Information on resource use and trophic dynamics of marine predators is important for understanding their role in ecosystem functioning and predicting population‐level responses to environmental change.

Dynamics and pattern formation in diffusive predator-prey models with predator-taxis

Electronic Journal of Differential Equations, 2020
We consider a three-species predator-prey system in which the predator has a stage structure and the prey moves to avoid the mature predator, which is called the predator-taxis.

A critical assessment of marine predator isoscapes within the southern Indian Ocean

Movement Ecology, 2020
Background Precise and accurate retrospective geolocation of marine predators via their tissues’ isotopic composition relies on quality reference maps of relevant isotopic gradients (“isoscapes”).

Predation and accumulation [PDF]

Journal of Economic Growth, 1995
This article incorporates the economic theory of predation into the theory of economic growth. The analytical framework is a general-equilibrium model of the interaction between two dynasties: a potential predator and its prey. We find that the rate of accumulation of capital and the security of property are positively related only for generations of ...

When is general wariness favored in avoiding multiple predator types? [PDF]

, 2012
Free access to article and electronic appendices via DOI.Adaptive responses to predation are generally studied assuming only one predator type exists, but most prey species are depredated by multiple types.

Predators avoiding predation [PDF]

Proceedings of the National Academy of Sciences, 2008
The notion of stealthy predation often invokes images of a predator hiding and waiting to ambush its unsuspecting prey. In this issue of PNAS, Manicom et al. (1) offer an alternative reason why predators hide that involves an important tradeoff between capturing prey and seeking refuge to avoid their own demise from other predator species.

Super machine learning: improving accuracy and reducing variance of behaviour classification from accelerometry

Animal Biotelemetry, 2017
Background Semi-automating the analyses of accelerometry data makes it possible to synthesize large data sets. However, when constructing activity budgets from accelerometry data, there are many methods to extract, analyse and report data and results ...

Threat-sensitive anti-predator defence in precocial wader, the northern lapwing Vanellus vanellus [PDF]

, 2016
Birds exhibit various forms of anti-predator behaviours to avoid reproductive failure, with mobbing—observation, approach and usually harassment of a predator—being one of the most commonly observed. Here, we investigate patterns of temporal variation in
