Nosema bombi: A pollinator parasite with detrimental fitness effects.
TLDR
When infection occurred at an early stage of colony development, virtually all individuals were infected, with spores being found in a number of tissues, and the functional fitness of males and young queens was reduced to zero, and N. bombi appears to decrease its opportunities for transmission to the next host generation. Expand
Unifying external and internal immune defences.
TLDR
It is argued that antimicrobial secretions represent an extended arm of the immune system, forming an underappreciated selective force in the evolution of immune systems. Expand
Cichlids do not adjust reproductive skew to the availability of independent breeding options
TLDR
The results suggest that tug-of-war models based on competition over reproduction within groups describe best the reproductive skew observed in the study system, and suggests that male breeder-male helper reproductive conflicts may be alleviated by females producing larger clutches with helpers around. Expand
A field experiment on the effect of Nosema bombi in colonies of the bumblebee Bombus terrestris
TLDR
This study investigates whether N. bombi also has negative fitness effects under natural conditions. Expand
IMMUNE RESPONSE INCREASES PREDATION RISK
TLDR
It is concluded that some costs of immunity are expressed via increased susceptibility to predation, indicating the importance of integrating the ecological context when investigating optimal investment in immunity. Expand
Bacteriolytic Activity in the Ejaculate of an Insect
TLDR
The results suggest that sperm‐microbe interactions are probably important in the evolution of ejaculate components and thereby provide a route for natural selection to account for some of the diversity of seminal components. Expand
In vitro antimicrobial sperm protection by an ejaculate‐like substance
TLDR
The data support the idea of a naturally selected origin of ejaculate components and provide a mechanistically well-defined pathway how sexual selection can affect ejaculate composition via antimicrobial sperm protection. Expand
Genitalia‐associated microbes in insects
TLDR
A case is made for studies in sexual selection, especially the ones investigating postcopulatory processes, that should incorporate environmental, as well as genotypic variation, in reproductive traits, that indicate a role for natural selection in shaping the evolution of reproductive traits. Expand
Diel variation in a dynamic sexual display and its association with female mate-searching behaviour
TLDR
It is suggested that males differing in nutritional condition may optimize their investment in signalling in relation to time of day as to maximize mating success. Expand
