Demographic aspects of Chrysomya megracephala (Diptera, Calliphoridae) adults maintained under experimental conditions: Reproductive rate estimates
(Inst Tecnologia Parana, 2006-05-01)
The objective of this work was to evaluate some aspects of the populational ecology of Chrysomya megacephala, analyzing demographic aspects of adults kept under experimental conditions. Cages of C. megacephala adults were ...
Brood cell size of Apis mellifera modifies the reproductive behavior of Varroa destructor
(SPRINGER, 2010)
We undertook a field study to determine whether comb cell size affects the reproductive behavior of Varroa destructor under natural conditions. We examined the effect of brood cell width on the reproductive behavior of V. ...

Vectorial capacity, basic reproduction number, force of infection and all that: formal notation to complete and adjust their classical concepts and equations
(FUNDACO OSWALDO CRUZRIO DE JANEIRO, RJ, 2012)
A dimensional analysis of the classical equations related to the dynamics of vector-borne infections is presented. It is provided a formal notation to complete the expressions for the Ross' threshold theorem, the Macdonald's ...
Maternal age influences on reproductive rates in Nile tilapia (Oreochromis niloticus)
(Revista Brasileira Zootecnia Brazilian Journal Animal Sci, 2015-04-01)
In this study we examined the effects of the maternal age on the fecundity (absolute and relative), egg production, and fertilization rates of Nile tilapia (Oreochromis niloticus). Females were divided into three groups: ...
Phenology of a dioecious population of Batrachospermum delicatulum (Batrachospermales, Rhodophyta) in a stream from southeastern Brazil
(1999-12-01)
The seasonal dynamics of a dioecious population of Batrachospermum delicatulum (Skuja) Necchi and Entwisle was evaluated biweekly during the growth period of the macroscopic gametophyte, from late autumn (May) to early ...
