The Energetics and Scaling of Search Strategies in Bacteria

摘要: Abstract: The influence of body size on the energetic cost movement is well studied in animals but has been rarely investigated bacteria. Here, I calculate four chemotactic strategies for different‐sized bacteria by adding costs their locomotion and reorientation. Size differences 0.1 μm result 100,000‐fold changes chemotaxis. exact any given a nonlinear function flagella length, minimum speed necessary to detect respond signal, gradient signal. These parameters are interlinked such way that strategy tightly coupled particular environmental gradients, offering avenues explaining exploring diversity competition. analysis here implications beyond Power‐law regression through transport different kinds chemotaxis same slope as swimming animals, suggesting universal allometric equation all ...
