摘要:Evolutionary theory predicts that animals should forage to maximize their fitness, which in predators is traditionally assumed equivalent to maximizing energy intake rather than balancing the intake of specific nutrients. We restricted female predatory ground beetles (Anchomenus ...

摘要:The disposable soma hypothesis posits a negative correlation between longevity and reproduction, presumably because these aspects of fitness compete for a limited pool of nutrients. However, diet, which varies widely among animals, could affect the availability of key nutrients r...

摘要:Conservation physiology (CP) and nutritional ecology (NE) are both integrative sciences that share the fundamental aim of understanding the patterns, mechanisms and consequences of animal responses to changing environments. Here, we explore the high-level similarities and differe...

摘要:The Protein Leverage Hypothesis (PLH) predicts that humans prioritize protein when regulating food intake. We tested a central prediction of PLH: protein intake will remain more constant than fat or carbohydrate in the face of dietary changes in a free-living population. Data com...

摘要:Syngeneic bone marrow transplantation into the adult tgepsilon26 mouse results in severe wasting disease and colitis. On transplantation, the rudimentary thymus of the adult tgepsilon26 mouse repopulates briefly but quickly regresses in temporal association with the onset of coli...

摘要:We examined the ecdysteroid content of eggs from crowd-reared and solitary-reared desert locusts, Schistocerca gregaria, throughout embryogenesis from the day of egg laying until shortly before hatching on day 14. Depending on the time during incubation, ecdysteroid content in eg...

摘要:Rearing locusts in an impoverished chemosensory environment leads to fewer chemoreceptors developing on the mouthparts and antennae as adults but the behavioural relevance of these changes remains unknown. To address this question, locusts were reared for the final two larval sta...

摘要:Desert locusts (Schistocerca gregaria) can undergo a profound transformation between solitarious and gregarious forms, which involves widespread changes in behaviour, physiology and morphology. This phase change is triggered by the presence or absence of other locusts and occurs ...

摘要:Nutritional regulatory responses were compared between solitarious and gregarious phases of the African armyworm, Spodoptera exempta. When allowed to mix between two nutritionally imbalanced but complementary foods, final-instar caterpillars in both phases selected a diet compris...
