Can Wolf Predation Immediately Alter the Foraging Behavior of Beavers?: Video of a Wolf Killing a Foraging Beaver

open access: yesEcology and Evolution
Knowledge of wolf (Canis lupus)‐beaver (Castor canadensis) interactions has largely been derived from indirect observations due to the cryptic nature of wolves and the densely forested areas where they usually kill beavers. In September 2023, we captured

The mechanistic basis of Myxococcus xanthus rippling behavior and its physiological role during predation. [PDF]

open access: yesPLoS Computational Biology, 2012
Myxococcus xanthus cells self-organize into periodic bands of traveling waves, termed ripples, during multicellular fruiting body development and predation on other bacteria. To investigate the mechanistic basis of rippling behavior and its physiological

The predatory behavior of the Neotropical social wasp Polybia rejecta [PDF]

open access: yesBehavioural Processes, 2017
We experimentally studied the predatory behavior of Polybia rejecta (Vespidae, Polistinae, Epiponini) towards 2-88 mm-long insects attracted to a UV light trap. Foragers, which began to hunt at 6:30, selected 4-14 mm-long prey insects. Prey detection by sight by hovering wasps was confirmed using decoys.

In situ predatory behavior ofMysis relicta in Lake Michigan [PDF]

open access: yesHydrobiologia, 1982
Selectivity coefficients (W′) and predation rates on Lake Michigan zooplankton were determined forMysis relicta during spring through fall using anin situ method. W′ values indicated the following ranked order of prey preference: Cladocera > copepod copepodites and copepod nauplii > adult diaptomids and cyclopoids.

Games judges don't play: predatory pricing and strategic reasoning in US antitrust [PDF]

open access: yes
The paper analyzes the last three decades of debates on predatory pricing in US antitrust law, starting from the literature which followed Areeda & Turner 1975 and ending with the early years of the new century, after the Brooke decision.

Temperature effects on predatory behavior and interspecific competition of Sacramento pikeminnow and largemouth bass [PDF]

open access: yes, 2020
My research is focused on the predatory behavior of two fish species, largemouth bass and Sacramento pikeminnow, and the effects of temperature on this behavior.

Effect of water depth on predation frequency by diving beetles on mosquito larvae prey [PDF]

open access: yes, 2015
Diving behavior and its frequency may differ among species of mosquito larvae because of differences in predation pressure. The present study aimed to investigate the relationship between water depth and predation frequency on two mosquito species, Culex

Seasonal plasticity in anti‐predatory strategies: Matching of color and color preference for effective crypsis

open access: yesEvolution Letters, 2019
Effective anti‐predatory strategies typically require matching appearance and behavior in prey, and there are many compelling examples of behavioral repertoires that enhance the effectiveness of morphological defenses. When protective adult morphology is

Competition or Predation? Schumpeterian Rivalry in Network Markets [PDF]

open access: yes
We explore the logic of predation and rules designed to prevent it in markets subject to network effects. Although, as many have informally argued, predatory behavior is plausibly more likely to succeed in such markets, we find that it is particularly ...

Caffeine effects on the predatory behavior of the orb-weaving spider, Argiope argentata [PDF]

open access: yes, 2004
Argiope argentata are orb-weaving spiders--meaning that their webs are a sticky spiral wound around radii extending from a central hub. A. argentata have poor vision and depend on vibrations in their web for detection of prey. A.
