Immature cockroaches increased energy use by only about 35% carrying loads equal to their body mass, far less than the expected twofold increase and this cost did not change over days.

ABSTRACT ECR Spotlight is a series of interviews with early-career authors from a selection of papers published in Journal of Experimental Biology and aims to promote not only the diversity of early-career researchers (ECRs) working in experimental biology but also the huge variety of animals and physiological systems that are essential for the ‘comparative’ approach. Be Eldash is an author on ‘ Economic load-carrying in immature cockroaches’, published in JEB. Be is a PhD student in the lab of Ruud Schilder at Department of Biology, Pennsylvania State University, USA, investigating how animal locomotor systems are affected by environmental conditions and biological characteristics, particularly body size, energetics and metabolism.
A Sun, study conducted a other in Immature cockroaches tested for energetic cost of load carrying during locomotion. Load carrying equal to body mass vs. No load carrying (baseline) was evaluated on Energetic cost of locomotion measured as energy use while running after adding load equal to body mass (35% increase in energy use compared to baseline). Immature cockroaches increased energy use by only about 35% carrying loads equal to their body mass, far less than the expected twofold increase and this cost did not change over days.
