Papanastasiou, S. A.; Nakas, C. T.; Carey, J. R.; Papadopoulos, N. T. (2013)Background: In various species mating exerts direct and indirect effects on female demographic traits ranging from life span shortening to behavioural shifts.

Cost of reproduction in male medflies: The primacy of sexual courting in extreme longevity reduction
Papadopoulos, N. T.; Liedo, P.; Müller, H. G.; Wang, J. L.; Molleman, F.; Carey, J. R. (2010)In polygynous insect species, male reproductive success is directly related to lifetime mating success. However, the costs for males of sexual activities such as courting, signaling, and mating are largely unknown. We ... -
Demographic window to aging in the wild: Constructing life tables and estimating survival functions from marked individuals of unknown age
Müller, H. G.; Wang, J. L.; Carey, J. R.; Caswell-Chen, E. P.; Chen, C.; Papadopoulos, N.; Yao, F. (2004)We address the problem of establishing a survival schedule for wild populations. A demographic key identity is established, leading to a method whereby age-specific survival and mortality can be deduced from a marked cohort ... -
Dietary effects on sex-specific health dynamics of medfly: Support for the dynamic equilibrium model of aging
Papadopoulos, N. T.; Papanastasiou, S.; Müller, H. G.; Wang, J. L.; Yang, W.; Carey, J. R. (2011)We examined experimentally the relationship between the period of unhealthy life and longevity in the medfly by using the first sign of supine behavior (upside down; immobile) in medflies as an indication of their poor ... -
Dual reproductive cost of aging in male medflies: Dramatic decrease in mating competitiveness and gradual reduction in mating performance
Papanastasiou, S. A.; Diamantidis, A. D.; Nakas, C. T.; Carey, J. R.; Papadopoulos, N. T. (2011)Although age-based effects on the reproductive success of males have been reported in several animal taxa the cost of aging on male mating success in lekking species has not been fully explored. We used the Mediterranean ... -
Estimating changes in mean population age using the death distributions of live-captured medflies
Carey, J. R.; Papadopoulos, N. T.; Papanastasiou, S.; Diamantidis, A.; Nakas, C. T. (2012)1. A simple, low-cost approach to estimating population ageing was introduced based on a modified version of the captive cohort method a technique developed earlier (Carey et al., Aging Cell, 7, 426437, 2008) in which ... -
Exceptional Longevity in the Tephritid, Ceratitis rosa, a Close Relative of the Mediterranean Fruit Fly
Duyck, P. F.; Kouloussis, N. A.; Papadopoulos, N. T.; Quilici, S.; Carey, J. R. (2012)This study shows that the fruit fly, Ceratitis rosa (Karsch), has a significantly longer life span than the medfly, C. capitata (Wiedemann); the species used as a model organism for the demographics of insect aging. This ... -
From trickle to flood: the large-scale, cryptic invasion of California by tropical fruit flies
Papadopoulos, N. T.; Plant, R. E.; Carey, J. R. (2013)Since 1954, when the first tropical tephritid fruit fly was detected in California, a total of 17 species in four genera and 11 386 individuals (adults/larvae) have been detected in the state at more than 3348 locations ... -
Graphical and demographic synopsis of the captive cohort method for estimating population age structure in the wild
Carey, J. R.; Müller, H. G.; Wang, J. L.; Papadopoulos, N. T.; Diamantidis, A.; Koulousis, N. A. (2012)The purpose of this paper is to complement the literature concerned with the captive cohort method for estimating age structure including (1) graphic techniques to visualize and thus better understand the underlying life ... -

Life-history evolution of an invasive tephritid
Diamantidis, A. D.; Carey, J. R.; Papadopoulos, N. T. (2008)Natural selection and genetic drift may cause divergence in several life-history and behavioural traits among populations of cosmopolitan insect species that have evolved in allopatry. The Mediterranean fruit fly, Ceratitis ... -
