A mechanistic link between parasite resistance and expression of a sexually selected trait in a damselflyM T Siva-Jothy
Department of Animal and Plant Sciences, University of Sheffield
Proc Biol Sci 267:2523-7. 2000..These results suggest a shared, limiting resource may form the mechanistic basis of the trade-off between a condition-dependent signal trait and immune function in this system...
A matter of taste: direct detection of female mating status in the bedbugMichael T Siva-Jothy
Evolution and Behaviour Group, Department of Animal and Plant Sciences, University of Sheffield, Sheffield S10 2TN, UK
Proc Biol Sci 270:649-52. 2003..We discuss why male bedbugs might show this pattern of ejaculate-size adjustment...
Functional consequences of blood clotting in insectsEleanor R Haine
Department of Animal and Plant Sciences, University of Sheffield, Sheffield, UK
Dev Comp Immunol 31:456-64. 2007..Our results demonstrate that haemolymph coagulation has major functional consequences, the most important of which is the compartmentalisation of the open haemocoel...
Reducing a cost of traumatic insemination: female bedbugs evolve a unique organKlaus Reinhardt
Department of Animal and Plant Science, The University of Sheffield, Sheffield S10 2TN, UK
Proc Biol Sci 270:2371-5. 2003..We found no evidence that the spermalege reduces the costs of wound healing...
Biology of the bed bugs (Cimicidae)Klaus Reinhardt
Department of Animal and Plant Sciences, The University of Sheffield, Sheffield S10 2TN, UK
Annu Rev Entomol 52:351-74. 2007....
Adaptive innate immunity? Responsive-mode prophylaxis in the mealworm beetle, Tenebrio molitorYannick Moret
Department of Animal and Plant Sciences, University of Sheffield, Sheffield S10 2TN, UK
Proc Biol Sci 270:2475-80. 2003..These results suggest that the observed response is functionally "adaptive"...
Selection on insect immunity in the wildJens Rolff
Department of Animal and Plant Sciences, University of Sheffield, Sheffield S10 2TN, UK
Proc Biol Sci 271:2157-60. 2004..We suggest that positive selection on PO activity in the year of study may be explained by annual fluctuations in parasite loads...
Female-limited polymorphism in the copulatory organ of a traumatically inseminating insectKlaus Reinhardt
Department of Animal and Plant Sciences, University of Sheffield, Sheffield S10 2TN, United Kingdom
Am Nat 170:931-5. 2007....
Invertebrate ecological immunologyJ Rolff
Department of Animal and Plant Sciences, University of Sheffield, S10 2TN, Sheffield, UK
Science 301:472-5. 2003..Using this empirical base, we pose general questions in areas that are of central importance for the development of ecological immunology...
Examining costs of induced and constitutive immune investment in Tenebrio molitorS A O Armitage
Department of Animal and Plant Sciences, University of Sheffield, Sheffield, UK
J Evol Biol 16:1038-44. 2003..In contrast to other studies, this cost was expressed under ad libitum feeding conditions. We found no measurable costs for constitutive investment in immunity (prophylactic investment in cuticular colour)...
Estimating the mean abundance and feeding rate of a temporal ectoparasite in the wild: Afrocimex constrictus (Heteroptera: Cimicidae)Klaus Reinhardt
Department of Animal and Plant Sciences, Western Bank, The University of Sheffield, S10 2TN, UK
Int J Parasitol 37:937-42. 2007....
Immune function responds to selection for cuticular colour in Tenebrio molitorS A O Armitage
Department of Animal and Plant Sciences, University of Sheffield, Western Bank, Sheffield S10 2TN, UK
Heredity (Edinb) 94:650-6. 2005..Thus, the observed correlated response to selection upon cuticular colour and immune variables probably results from these traits' shared dependence on melanin production...
Temporal patterns in immune responses to a range of microbial insults (Tenebrio molitor)Eleanor R Haine
Department of Animal and Plant Sciences, University of Sheffield, Western Bank, Sheffield, S10 2TN, UK
J Insect Physiol 54:1090-7. 2008..There was no long-lasting upregulation of phenoloxidase activity, suggesting that this immune effector system is not involved in the management of microbial infections over a long time scale...
Situation exploitation: higher male mating success when female resistance is reduced by feedingKlaus Reinhardt
Department of Animal and Plant Sciences, University of Sheffield, Sheffield, United Kingdom
Evolution 63:29-39. 2009..Our results, therefore, suggest that males have increased mating success in a situation that females cannot avoid because it is naturally selected. Such "situation exploitation" of low resistance may be a common phenomenon...
Dietary glycerol and adult access to water: effects on fecundity and longevity in the almond mothCamilla Ryne
Department of Animal and Plant Sciences, University of Sheffield, Sheffield S10 2TN, UK
J Insect Physiol 50:429-34. 2004..We also discuss the possibility that larval diet can affect female reproductive decisions...
Antimicrobial defense and persistent infection in insectsEleanor R Haine
Department of Animal and Plant Sciences, University of Sheffield, Sheffield S10 2TN, UK
Science 322:1257-9. 2008..These findings suggest that understanding of the management of antimicrobial peptides in natural systems might inform medical treatment strategies that avoid the risk of drug resistance...
Modulation of sexual signalling by immune challenged male mealworm beetles (Tenebrio molitor, L.): evidence for terminal investment and dishonestyB Sadd
Department of Animal and Plant Sciences, University of Sheffield, Sheffield, UK
J Evol Biol 19:321-5. 2006..In other words males increase terminal reproductive effort (invest in attractiveness) in response to a survival threat (immune insult). Consequently the signal preferred by the female is dishonest when considering the male's condition...
