PREDATOR: Registration of 3D Point Clouds with Low Overlap [PDF]
Computer Vision and Pattern Recognition, 2020 We introduce PREDATOR, a model for pairwise point-cloud registration with deep attention to the overlap region. Different from previous work, our model is specifically designed to handle (also) point-cloud pairs with low overlap.

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.

The context dependence of non-consumptive predator effects.
Ecology Letters, 2020 Non-consumptive predator effects (NCEs) are now widely recognised for their capacity to shape ecosystem structure and function. Yet, forecasting the propagation of these predator-induced trait changes through particular communities remains a challenge ...

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.

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.

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.

A review of thanatosis (death feigning) as an anti-predator behaviour
Behavioral Ecology and Sociobiology, 2018 Thanatosis—also known as death-feigning and, we argue more appropriately, tonic immobility (TI)—is an under-reported but fascinating anti-predator strategy adopted by diverse prey late on in the predation sequence, and frequently following physical ...

Morphometry of the reproductive system of the predator Podisus nigrispinus (Dallas, 1851) (Hemiptera, Pentatomidae) when submitted to different temperatures [PDF]
Ciência Rural, 2020 : In order to manipulate the mass rearing of natural enemies, temperature variations can be used. The effects are widely studied for their survival and developmental duration; however, there is little information about their reproductive system in the ...

The utility of accelerometers to predict stroke rate in captive fur seals and sea lions
Biology Open, 2017 The energy expenditure of free-living fur seals and sea lions is difficult to measure directly, but may be indirectly derived from flipper stroke rate. We filmed 10 captive otariids swimming with accelerometers either attached to a harness (Daily Diary ...
