13. Use of assisted reproductive technology to separate sperm from human immunodeficiency virus infected men resulting in pregnancy among serodiscordant couples
Due to HIV care improvement, discordant couples more frequently seek help in order to conceive their own biological child. Besides the advance of antiretroviral therapy, unprotected intercourse is not a complete safe option, carrying a low but still present risk of HIV transmission. We report 10 serodiscordant couples in whom the male partner is HIV positive

14. Effect of social instigation and aggressive behavior on hormone levels of lactating dams and adult male Wistar rats
Among rodents, maternal aggression in the postpartum period represents a species-typical adaptation, but when aggressive behavior increases beyond this adaptive level, it can represent a model of excessive aggression. This study assessed the neuroendocrine response of lactating rats and socially instigated male rats. The aim of the present study was to asses

15. Offspring production in three freshwater crab species (Brachyura: Pseudothelphusidae) from the Amazon region and Central America
Freshwater crabs are an important component of the fauna of limnic environments, and out of the two true freshwater crab families present in the Neotropics, Pseudothelphusidae is the most diverse. Considering the lack of information regarding reproductive features of neotropical freshwater crabs, we studied, for the first time, the fecundity and the presence

16. Parental care in four sympatric species of Leptodactylus (Anura, Leptodactylidae) / Cuidado parental em quatro espécies simpátricas de Leptodactylus (Anura; Leptodactylidae)
Maternal care to tadpole shoals occur in four species of Leptodactylus that occur in the Cerrado of the Triângulo Mineiro. Here we described and quantify features of the maternal care for these species. We presented a list of behaviors related performed by the carrying females and determined if, in L. ocellatus, L. podicipinus, and L. cf. leptodactyloides t

17. Ocorrência e Interações de Recém-nascidos e Filhotes de golfinho-rotador Stenella longirostris na Baía dos Golfinhos, Fernando de Noronha
Studies indicate that spinner dolphins use the Baía dos Golfinhos, in Fernando de Noronha Archipelago, for resting, reproduction, parental care and protection against shark attacks. The present study had the purpose of verifying the seasonality of spinner dolphin newborns and calves in relation to the months of the year and the pluviometric seasons (dry and

18. Narcisismo e função parental: Incursões na clínica, teoria psicanalítica e literatura
This work is an outcome of a bibliographic research and a theoretical discussion about narcissism and parental function. We emphasize these two concepts because we think they can make it possible to carry out a Freudian psychoanalytic understanding of the relationship between parents and offspring, discussing the metapsychological issues involved. We are not

19. Biologia reprodutiva de Vanellus chilensis (Aves: Charadriidae) : por que reproduzir em grupo?
It has been recently demonstrated that females can reduce their egg investment without incurring costs onto the developing embryos. This happens when females breed in the presence of helpers-at-the-nest that compensate for the egg nutrient reduction by bringing more food for the chicks. Using the southern lapwing (Vanellus chilensis) as the study subject, th

20. Reproduction of Leptodactylus ocellatus (Anura, Leptodactylidae), a species with maternal care to the offspring / Reprodução de Leptodactylus ocellatus (Anura, Leptodactylidae), uma espécie com cuidado maternal à prole
In Leptodactylus ocellatus, the tadpoles form schools that are protected by the females until the end of the larval phase. Here we described aspects of the reproduction of this species in areas of Cerrado in the state of Minas Gerais (Brazil). We determined in the field the reproductive period, spawning places, duration of the parental care and differences i

21. Hymenoptera marking technique
In true social hymenopterans, such as many species of bees, wasps and all species of ants, the main characteristics are the overlapping of generations, the care with the offspring and the division of labor among the members of the colony. The first biological feature means that in a same moment there are groups of individuals, with variable ages, that execut

22. Reproductive biology of the harvestman Iporangaia pustulosa (Arachnida: Opiliones): sexual selection and evolution of paternal care / Biologia reprodutiva do opilião Iporangaia pustulosa (Arachnida: Opiliones) : seleção sexual e evolução do cuidado paternal
Exclusive paternal care is rare reproductive strategy that and has evolved only in the order Opiliones among arachnids. Although nearly half of the independent events of evolution of this behavior in arthropods has occurred in the order Opiliones, only a few studies have investigated in detail the reproductive biology of harvestmen species. Iporangaia pustul

23. Pesquisa de anticorpos contra bactérias do gênero Brucella spp, Leptospira spp, Chlamydophila spp em tamanduás-bandeira (Myrmecophaga tridactyla, Linnaeus, 1758), da RPPN SESC Pantanal, Parque Nacional da Serra da Canastra (PNSC) e Parque Nacional das Emas (PNE) / Research on antibodies against bacteria of the Brucella spp, Leptospira spp, Chlamydophila spp species in Anteaters (Myrmecophaga tridactyla,Linnaeus,1758) of the Natural Assets Private Reserve RPPN of SESC Pantanal, the Serra da Canastra National Park and the Emas National Park
The fragility of the giant Anteater (Myrmecophaga tridactyla) and the disappearance of this animal from certain regions, including areas of original distribution, clearly indicates the necessity of adopting protective measures. Ecology studies consider diseases as regulatory mechanisms for natural populations, thus indicating that the study of the role of di
