Foram utilizados 1600 pintos de corte de um dia de idade, distribuídos em delineamento, em blocos ao acaso, com esquema fatorial 4×2 (quatro linhagens, sendo uma delas comercial (Ross-308) e as demais específicas para a produção colonial (Caipirinha, Pescoço Pelado e Paraíso Pedrês) e dois sistemas de criação (confinado e com acesso a piquete), com quatro repetições de 50 aves cada. A ração não continha promotores químicos de crescimento e produtos de origem animal. Avaliaram-se o ganho de peso, o consumo de ração, a conversão alimentar, a mortalidade e os rendimentos de carcaça e das partes (peito, pernas, asas e dorso) aos 56, 63, 70, 77 e 84 dias de idade. O comprimento e a porcentagem (em relação ao peso vivo) dos intestinos e o peso e a porcentagem (em relação ao peso vivo) do fígado, moela e pâncreas foram avaliados aos 84 dias de idade. Houve efeito (P<0,05) da linhagem para as características de desempenho e da linhagem e do sexo para rendimentos da carcaça e das partes, assim como para as características do sistema digestório (P<0,05). O sistema de criação não influenciou as características avaliadas.

This article analyzes the degree of thermopluviometric influence on certain indicators in the commerce of Maringa, state of Parana. To the end, climate elements, such as the temperature and prectipitation as well as certain economic indicators, namely: ICMS (taxes), SCPC, Video-Check, Consumption and Consumers of Electric Energy were studied. Graphical analyses along with statistical applications of correlation and regression were performed, as well as the examination of a case study. It is believed that the groups investigated showed variations in the forms of correlation. The results herein presented are in the manner of preliminary trial, representing a first attempt at measuring the actual relationship between the climatic variables (temperature and precipitation) with certain behavioural indicators of commerce in the city of Maringa.

The paper aims at increasing the knowledge on the ecology of Polistes canadensis canadensis colonies in a Caatinga region. We studied some aspects of P.c. canadensis nesting habitats and colonial productivity. In the environmental conditions studied, this species nests on several types of substrata, particulary on thorny plants and in caves. The colony productivity and the cell reoccupation rate varies from one colony to another. In some colonies, we found cells with one, two and, more rarely, three reoccupations, this is upto four individuals produced in one cell only. The rate of the first reoccupation was 2.88-34.78%, with na average rate of 15.96%. The number of adults produced by the colonies of Flc, canadensis varied from 10 to 576 individuals. Productivity, given by the relationship between the number of born adults and the number of cell existing in the nest, varied from 31.25 to 123.19% and presented an average of 88.50%.

The colonial orb-weaving spider, Eriophora bistriata, coordinates molting cycles through communication. Colonies with differing molting cycles synchronize when combined. Intercycle intervals depend upon food availability. The possible coordination of this synchrony by chemical communication among spiders is discussed. © 1988 Birkhäuser Verlag Basel.
