Root Foraging Influences Plant Growth Responses to Earthworm Foraging
Interactions among the foraging behaviours of co-occurring animal species can impact population and community dynamics; the consequences of interactions between plant and animal foraging behaviours have received less attention. In North American forests, invasions by European earthworms have led to substantial changes in plant community composition. Changes in leaf litter have been identified a...
متن کاملFocusing the metaphor: plant root foraging behaviour.
Many authors assert that plants exhibit complex behaviours which are analogous to animal behaviour. However, plant ecologists rarely root these studies in a conceptual foundation as fertile as that used by animal behaviourists. Here we adapt the optimality principles that facilitated numerous advances in the study of animal foraging behaviour to create one possible framework for plant foraging ...
متن کاملUpdate on Root Nutrient Foraging Root Nutrient Foraging
During a plant’s lifecycle, the availability of nutrients in the soil is mostly heterogeneous in space and time. Plants are able to adapt to nutrient shortage or localized nutrient availability by altering their root system architecture to efficiently explore soil zones containing the limited nutrient. It has been shown that the deficiency of different nutrients induces root architectural and m...
متن کاملAdaptive Evolution of Plastic Foraging Responses in a Clonal Plant
Stoloniferous rosette plants may show horizontal and vertical foraging responses, such as changes in branching frequency, stolon internode length, leaf length, and height growth of stolons. To study whether such plastic foraging responses constitute an adaptation to heterogeneity in competition, we studied genetic variation in and fitness consequences of plastic foraging responses in the stolon...
متن کاملResponses of foraging hedgehogs to badger odour
Enclosure and field trials were used to investigate the responses of hedgehogs, Erinaceus europaeus, to predator (badger,Meles meles) and non-predator odours. Two hypotheses were tested: (1) hedgehogs are capable of responding to badger odour; and (2) hedgehogs prefer not to forage in areas tainted with badger odour. In enclosure trials, hedgehogs almost exclusively avoided feeding at sites tai...
