13. Sexual Systems of Plants in a Brazilian Montane Forest
ABSTRACT In this study, vegetation reproduction has been investigated in order to understand aspects of speciation, structuring and composition of plant communities. Thus, we sought to characterize the frequency of sexual systems from species recorded in seed rain occurring in a tropical rainforest (Atlantic Forest) in Caparaó National Park, Espírito Santo

15. Histopathological characterization of Coffea arabica cultivar IPR 106 resistance to Meloidogyne paranaensis
ABSTRACT: Meloidogyne species are widely distributed in coffee growing areas in Brazil, where M. paranaensis is responsible to significant losses to the crop. One of the main management strategies is the use of resistant cultivars, such as Apoatã rootstock and cultivars IPR 100 and IPR 106. However, the parasitic relationship between coffee and M. paranaens

17. Reproduction, feeding and migration patterns of Prochilodus nigricans (Characiformes: Prochilodontidae) in northeastern Ecuador
ABSTRACT The black prochilodus, Prochilodus nigricans, is an important food fish distributed throughout aquatic habitats of the Ecuadorian Amazon. We sampled gonad weight, body condition, and feeding of this species to address the question of whether changes in these biological parameters are related to hydrological variation and migration patterns. High fre

18. Population dynamics of Siderastrea stellata Verrill, 1868 from Rocas Atoll, RN: implications for predicted climate change impacts at the only South Atlantic atoll
ABSTRACT Coral reefs are one of the most vulnerable ecosystems to ocean warming and acidification, and it is important to determine the role of reef building species in this environment in order to obtain insight into their susceptibility to expected impacts of global changes. Aspects of the life history of a coral population, such as reproduction, growth an

19. Influence of artificial lighting on the performance and egg quality of commercial layers: a review
In Brazil, the egg production chain produces fresh eggs for the consumer market and for processing. Layers are housed in battery cage systems. Rearing and development farms are separate from egg-production farms. Considering the recent advance of Brazilian chicken egg production, scientific knowledge on management practices are required to disseminate and to

20. Use of the arbuscular mycorrhizal fungus Glomus intraradices as biological control agent of the nematode Nacobbus aberrans parasitizing tomato
The plant-parasitic nematode Nacobbus aberrans is an endoparasite that induces gall formation in the roots and causes severe losses to diverse crops. Some populations of this nematode show preference for certain hosts, revealing the existence of "races/groups" with different behaviour and making nematode management difficult. A possible biological control al

21. Reproduction and management of the mangrove crab Ucides cordatus (Crustacea, Brachyura, Ucididae) at Iguape, São Paulo, Brazil
O caranguejo de manguezal Ucides cordatus é um dos crustáceos mais explorados do Brasil. O presente estudo investigou a época reprodutiva desta espécie e o período do fenômeno da “andada”, quando os caranguejos estão ativos fora das tocas e ocorrem comportamentos agonísticos. Além disso, estes fatores foram relacionados com fatores ambientais em

22. El problema del desempleo en Argentina y el surgimiento de los Planes de Empleo y sostenimiento de ingresos en la agenda pública
This article aims to develop an analysis of the problem of unemployment and how the employment and income support programs emerge on the public agenda as mechanisms of the state institution to answer that question. This objective is part of a larger question, which attempts to relate the dynamics of social assistance policies, with building forms of citizens

24. Reproductive biology of the coypu, Myocastor coypus (Rodentia: Myocastoridae) in western Japan
We describe the reproductive biology of the coypu, Myocastor coypus (Molina, 1782), in western Japan, as an attempt to contribute to an efficient population control program of the coypu population. A total of 212 specimens (113 males and 99 females) were collected in the Tottori prefecture from February 2010 to January 2012. From the age estimation based on
