Immune function and parasite resistance in male and polymorphic female Coenagrion puellaGerrit Joop
Zoologisches Institut, AG Okologie, Technische Universitat Braunschweig, Braunschweig, Germany
BMC Evol Biol 6:19. 2006....
Bateman's principle and immunityJens Rolff
Evolution and Behaviour, Department of Animal and Plant Sciences, University of Sheffield Sheffield S10 2TN, UK
Proc Biol Sci 269:867-72. 2002..In support of my arguments, I mainly use studies on insects that share innate immunity with vertebrates and have the advantage that they are easier to study...
Why did the acquired immune system of vertebrates evolve?Jens Rolff
Animal and Plant Sciences, University of Sheffield, S10 2TN, Sheffield, UK
Dev Comp Immunol 31:476-82. 2007..These combine to shape a powerful multi-level and multi-causal selective scenario that I propose could have moulded the acquired immune system...
Genetic constraints and sexual dimorphism in immune defenseJens Rolff
Animal and Plant Sciences, University of Sheffield, United Kingdom
Evolution 59:1844-50. 2005..We furthermore show negative genetic correlations, strong indications of trade-offs, between immune traits for two pairs of traits in females...
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...
Time constraints decouple age and size at maturity and physiological traitsJens Rolff
Department of Animal and Plant Sciences, University of Sheffield, Sheffield S10 2TN, United Kingdom
Am Nat 164:559-65. 2004..Intriguingly, the physiological responses are partly decoupled from age and size at maturity, which indicates that the predictive value of traits such as age and size at maturity might well be restricted...
Selection for parasitoid resistance alters mating success in DrosophilaJens Rolff
Department of Animal and Plant Sciences, University of Sheffield, Western Bank, Sheffield S10 2TN, UK
Proc Biol Sci 270:S154-5. 2003..Parasitoid-resistant Drosophila melanogaster males achieved a higher mating success compared with non-resistant conspecifics. The underlying mechanism however remains elusive...
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...
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...
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...
Copulation corrupts immunity: a mechanism for a cost of mating in insectsJens Rolff
Department of Animal and Plant Sciences, University of Sheffield, Sheffield S10 2TN, United Kingdom
Proc Natl Acad Sci U S A 99:9916-8. 2002....
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...
Time constraints mediate predator-induced plasticity in immune function, condition, and life historyRobby Stoks
Laboratory of Aquatic Ecology, University of Leuven, , B-3000 Leuven, Belgium
Ecology 87:809-15. 2006..This indicates that predators can induce sublethal costs linked to both life history and physiology in their prey, and that time constraints can independently reduce the impact of predator-induced changes in life history and physiology...
