Increased fire frequency usually erodes microenvironmental conditions, causing a drastic limitation of edaphic resources. Thus, the production permanently closed-small flowers (cleistogamous, CL) should increase in sites with high as this implies less expensive reproductive assurance strategy. However, because open, insect-pollinated (chasmogamous, CH) have potential capacity to outcross via po...

When social constraints on the expression of mate preferences are absent, variation in offspring viability is predicted to favour females and males that display mate preferences. Earlier studies showed that female and male house mice, Mus domesticus, tested individually and mated with preferred (P) partners had higher reproductive success and better progeny performance than individuals mated wi...

The objective of the present study was to evaluate intensity weight loss in beef heifers during gestation and its effects on progeny performance up 205 days age. Sixty pregnant aged 3 or 4 years, born between 2015 2017, from rotational cross Charolais Nellore breeds were used. Females divided according period (7, 14, 21%) age at first calving (3 years), a completely randomized design x 2 factor...
