- Functional flexibility in a spider's orb web
Summary: Testing of an orb weaver's predation strategy in distorted webs reveals that despite the distortion, spiders remained effective at identifying, locating and capturing prey, but take somewhat longer to do so.
- Temperature effects on metabolic scaling of a keystone freshwater crustacean depend on fish-predation regime
Highlighted Article: The metabolic pace of life of a species relates not only to body mass and temperature, but also to predation regime and the interactive effects of all three of these factors.
- Greater agility increases probability of survival in the endangered northern quoll
Summary: High agility and body condition are advantageous for survival in female endangered northern quolls; development of predictive models that incorporate both predator and prey locomotor performance will give greater understanding on the vulnerability of native species to introduced predators.
- Predator chemical cues decrease attack time and increase metabolic rate in an orb-web spider
Summary: Female orb-web spiders, Argiope keyserlingi, elevate their metabolic rate under the risk of predation, allowing them to respond quicker and spend less time on foraging, reducing their exposure to predators.
- Food mobility and the evolution of grasping behaviour: a case study in strepsirrhine primates
Summary: The frequency of hand grasping across 17 strepsirrhine species increases with a swinging motion of the food, clarifying the role of food mobility in the evolution of grasping hands in primates.
- Motion-in-depth perception and prey capture in the praying mantis Sphodromantis lineola
Summary: Both stereoscopic visual cues and changing luminance cues can enable detection of approaching objects. We show that mantises use looming rather than stereo cues to detect motion-in-depth.
- Predatory posture and performance in a precocious larval fish targeting evasive copepods
Highlighted Article: Investigation of a highly modified and previously undescribed fast-start of a larval coral-reef fish, which captures evasive copepod prey as early as 1 day after hatching.
- Specialized movement and laterality of fin-biting behaviour in Genyochromis mento in Lake Malawi
Summary: Fin-biting cichlids in Lake Malawi exhibit a lateralized preference for side of attack. Predatory fish aiming for prey that show escape behaviours may frequently present lateralized behaviour in predation.
- Should I stay or should I go? The settlement-inducing protein complex guides barnacle settlement decisions
Summary: Reminiscent of field observations on Balanus balanoides by D. Crisp, F.R.S. in 1961, Amphibalanus amphitrite cyprids behave dose-dependently to the presence of their settlement-inducing protein complex in laboratory conditions.
