Perinatal exposure to parasiticide ivermectin: Long-term effects on reproductive parameters of adult male rats
(2011-02-01)
Ivermectin is one of the most widely used antiparasitic drugs globally. The aim of this study was to evaluate the chronic effects of perinatal exposure to ivermectin on male reproductive parameters in rats. Pregnant rats ...
Number of conspecifics and reproduction in the invasive plant Eschscholzia californica (Papaveraceae): is there a pollinatormediated Allee effect?
(Wiley-Blackwell, 2015)
The component Allee effect has been defined as a positive relationship between any measure of individual fitness and the number or density of conspecifics'. Larger plant populations or large patches have shown a higher ...
Effects of the hydromethanolic extract of Austroplenckia populnea (Celastraceae) on reproductive parameters of male rats
(Elsevier B.V., 2002-09-01)
Austroplenckia populnea (Reiss.) Lundell. was selected for this study because it has been shown that some plants from the Celastraceae family have antifertility effects. Twelve adult male rats were treated with hydromethanolic ...
Maternal investment in egg production: environmental and population-specific effects on offspring performance in the snapping shrimp Alpheus nuttingi (Schmitt, 1924) (Decapoda, Alpheidae)
(BRILL ACADEMIC PUBLISHERS, 2010)
Among marine invertebrates, the overall biomass invested in egg production varies widely within populations, which can result from the interaction of endogenous and exogenous factors. Species that have constant reproduction ...
Effects of different spray formulations on the reproductive parameters of engorged Rhipicephalus (Boophilus) microplus females detached from experimentally infested cattle
(Elsevier B. V., 2015-09-25)
This present study aimed to evaluate the deleterious effects of some commercially available spray formulations (15% Cypermethrin+25% Chlorpyriphos+1% Citronellal and 8% Cypermethrin+60% Ethion) on the reproductive parameters ...

Climatic variables and altitude as predictors of anuran species richness and number of reproductive modes in Brazil
(2010-07-01)
Because anuran species are highly dependent on environmental variables, we hypothesized that anuran species richness and the number of reproductive modes from different Brazilian localities vary according to climatic and ...

Effect of temporary calf removal numbers in timed artificial insemination protocols on weaning weight from nelore calves
(2013-01-01)
This study was conducted to evaluate the effect on the weaning weight of Nelore calves from two factors: the number of times the calves were temporarily removed from their mothers during a timed artificial insemination ...
Reproductive effects in male rats exposed to diuron
(Elsevier B.V., 2007-01-01)
Diuron is a ureic herbicide considered to have very low toxicity. The present study evaluated several aspects of reproductive toxicity of diuron in adult male rats. Diuron was diluted in corn oil and administered by oral ...
