Dynamics of energy reserves and the cost of reproduction in female and male fiddler crabs
(Elsevier Gmbh, 2018-02)
The physiological costs of reproduction can be measured as the energy allocated to reproductive activities. In fiddler crabs, females allocate energy to vitellogenesis and brooding, whereas males perform expensive courtship ...
Cost effectiveness of diagnostic laparoscopy in reproductive aged females suffering from non-specific acute low abdominal pain
(Instituto de Salud Publica, Facultad de Medicina - Universidad Nacional de Colombia, 2005)
Are there costs in the repeated mating activities of female Southern stink bugs Nezara viridula?
(WILEY-BLACKWELL, 2011)
Mating is an energy demanding process, imposing risks to physical injuries, pathogen infection and predation. Nevertheless, repeated and multiple mating are widespread even in insect species where nuptial gifts are not ...
An individual-based model to estimate the daily energetic cost of Greater Rheas and its contribution on population recruitment
(Wiley, 2013-08)
An individual-based model for estimating the energetic costs in Rhea americana was developed considering their sexual and seasonal differences in the behavioral activities. The model includes as variables the individual’s ...
Egg-laying site, fecundity and degree of sexual size dimorphism in frogs
(Oxford Univ Press, 2020-11-01)
Female fecundity is an important selective force leading to female-biased sexual size dimorphism (SSD) in frogs. Because anurans exhibit diverse reproductive modes, we investigated whether variation in SSD and fecundity ...
Cost-effectiveness analysis of a hypothetical hepatitis C vaccine compared to antiviral therapy
(CAMBRIDGE UNIV PRESS, 2009)
We propose a mathematical model to simulate the dynamics of hepatitis C virus (HCV) infection in the state of Sao Paulo, Brazil. We assumed that a hypothetical vaccine, which cost was taken to be the initial cost of the ...
