Adaptive changes in size and age at metamorphosis can qualitatively vary with predator type and available defenses by Higginson, A. D, Ruxton, G. D

“…In many taxa the timing of metamorphosis is plastic in response to predation risk during the pre-metamorphic stage, and trends in both age and body size at…”

Density-dependent investment in costly anti-predator defences: an explanation for the weak survival benefit of group living by Daly, Derek, Higginson, A. D., Chen, Dong, Ruxton, G. D., Speed, M. P.

“…Ecology Letters (2012) A central explanation for group living across animal taxa is the reduced rate of attack by predators. However, many field observations…”

Dynamic state-dependent modelling predicts optimal usage patterns of responsive defences by Higginson, A. D, Ruxton, G. D

“…Chemical defences against predation often involve responses to specific predation events where the prey expels fluids, such as haemolymph or gut contents,…”

Paying for nectar with wingbeats: a new model of honeybee foraging by Higginson, A. D., Gilbert, F.

“…Honeybees acquire wing damage as they age and older foraging honeybees accept lavender inflorescences with fewer flowers. These indicate the operation of some…”

Accumulating wing damage affects foraging decisions in honeybees (Apis mellifera L.) by Higginson, A. D., Barnard, C. J.

“…1. Nectar‐foraging honeybees ( Apis mellifera ) on lavender ( Lavandula stoechas ) appear to forage so as to maximise net energy return from foraging bouts;…”

Diminishing returns drive altruists to help extended family by Kennedy, P., Sumner, S., Botha, P., Welton, N. J., Higginson, A. D., Radford, A. N.

“…Altruism between close relatives can be easily explained. However, paradoxes arise when organisms divert altruism towards more distantly related recipients. In…”

An adaptive response to uncertainty can lead to weight gain during dieting attempts by Higginson, A D, McNamara, J M

“…Peoples' attempts to lose weight by low calorie diets often result in weight gain because of over-compensatory overeating during lapses. Animals usually…”

Morphological correlates of nectar production used by honeybees by HIGGINSON, A.D, GILBERT, F.S, BARNARD, C.J

“…1. Honeybees foraging on lavender have been shown to choose inflorescences that are larger and have more flowers. If they are selecting optimally then these…”
