1. Comportamento territorial, vocalização e biologia reprodutiva de Allobates olfersioides (Anura: Aromobatidae)
RESUMO Em anfíbios a territorialidade, o cortejo elaborado e outras formas de comportamento, parecem estar mais associados a espécies que exibem o padrão de reprodução prolongado. A vocalização é um importante aspecto biológico relacionado à reprodução e ao comportamento social dos anuros. Este é o primeiro estudo com comportamento e vocalizaç�

2. Aspects of the reproductive behaviour and development of two forensically relevant species, Blaesoxipha (Gigantotheca) stallengi (Lahille, 1907) and Sarcophaga (Liopygia) ruficornis (Fabricius, 1794) (Diptera: Sarcophagidae)
Abstract We studied aspects of the reproductive behaviour and development of two species of Sarcophagidae (Diptera) of potential forensic importance, Blaesoxipha stallengi (Lahille, 1907) and Sarcophaga ruficornis (Fabricius, 1794), which are dominant in assemblages in dry forests in Northeastern Brazil. We described the behavioural acts associated with cour

3. Stalking Following the Breakup of Dating Relationships in Adolescence
Resumo Este estudo transversal e exploratório investigou a presença de stalking, no período pós-ruptura de relacionamentos afetivo-sexuais de adolescentes. Um total de 117 adolescentes foram identificados como vítimas de stalking por parte do ex-parceiro íntimo (62,4% meninas), com idade média de 16,87 anos (DP = 1.26), os quais foram comparados a um

4. The peculiar breeding biology of the Amazonian frog Allobates subfolionidificans (Aromobatidae)
ABSTRACT Allobates subfolionidificans is a vulnerable and endemic leaf-litter frog from the state of Acre, Brazilian Amazonia. We monitored a population of A. subfolionidificans through regular censuses and mark-recapture of 181 individuals during an entire breeding season to characterize its reproductive behavior. The space use of A. subfolionidificans indi

5. The reproductive biology of Pinguipes brasilianus Cuvier, 1829 (Osteichthyes: Pinguipedidae) in temperate rocky reefs of Argentina
ABSTRACT Pinguipes brasilianus is a conspicuous and abundant rocky-reef fish inhabiting the Northern Patagonian gulfs of Argentina, Southwest Atlantic. This study describes its reproductive biology in this region. We made macroscopic and histological descriptions of the testis and ovary development, analyzed the evolution of the gonadosomatic index (GSI) in

6. Sexual behavior of the digger wasp Sphex ingens Smith (Hymenoptera, Sphecidae)
A species' mating system depends on its spatial distribution and temporal availability of mating opportunities, as well as on the resources that create these opportunities. In addition, for many species, courtship is driven by specific behaviors that precede and follow copulation. Although Sphex ingens is a taxonomically well known species of digger wasp, it

7. Is more better? Sexual confusion during courtship between two sympatric and synchronic tarantulas: Acanthoscurria suina and Eupalaestrus weijenberghi
When two similar species co-occur in time and space, strong mechanisms isolating them from each other are expected. Acanthoscurria suina Pocock, 1903 and Eupalaestrus weijenberghi (Thorell, 1894) are two sympatric and synchronic tarantulas that inhabit burrows in Uruguay's meadows. Here we test how and when reproductive isolation operates between these speci

8. Molecular analysis of an odorant-binding protein gene in two sympatric species of Lutzomyia longipalpis s.l.
Lutzomyia longipalpis s.l. is the main vector of American visceral leishmaniasis (AVL) and occurs as a species complex. DNA samples from two Brazilian sympatric species that differ in pheromone and courtship song production were used to analyse molecular polymorphisms in an odorant-binding protein ( obp29 ) gene. OBPs are proteins related to olfaction and a

9. Influência da estacionalidade no comportamento de corte de Pipra rubrocapilla (Passeriformes: Pipridae) em um remanescente de mata atlântica no estado de Pernambuco.
A presença das estações seca e chuvosa regula o comportamento de muitas aves, que sincronizam período reprodutivo a essas diferentes condições. Sendo assim, o presente estudo teve por objeto avaliar a influência da estacionalidade no comportamento reprodutivo de P. rubrocapilla. Para a constatação dessa provavel influência, foram contados os compor

10. Reproductive behavior of the mangrove crab Ucides cordatus (Crustacea; Brachyura; Ucididae)
The aim of the present work was to study the reproductive behavior of the mangrove crab (Ucides cordatus) in the estuary of the Igaraçú River (Piauí, Brazil). Courtship and mating were observed in December 2007 and in January-March 2009. The most frequently observed reproductive behavior was the transference of eggs onto the abdomen of the female. Some di

11. Social and reproductive physiology and behavior of the Neotropical cichlid fish Cichlasoma dimerus under laboratory conditions
In this work we describe for the first time the social and reproductive behavior of the Neotropical fish Cichlasoma dimerus (Heckel, 1840) [Perciformes: Cichlidae], endemic to the Paraná River basin, using a comprehensive-integral approach, including morphological and physiological features. This substrate breeding fish has biparental care of the fry and pr

12. Reproductive behavior and parental roles of the cichlid fish Laetacara araguaiae
Descrevemos o comportamento reprodutivo do pequeno ciclídeo sul-americano Laetacara araguaiae em riachos do Brasil. Predizemos que essa espécie apresenta cooperação reprodutiva e divisão de trabalho entre machos e fêmeas, como ocorre em outras espécies de ciclídeos substrate-spawners. Assim, estudamos 34 casais nas fases pré-acasalamento (n = 11), o
