Extra-pair behavior is present in 76% of socially monogamous bird species with biparental care. This behavior may produce costs to females related to a reduction in paternal care. We estimated the percentage of extra-pair ...

The evolutionary effects of crowding on male courtship behavior were studied using wild and mass-reared medflies. Mass-reared strains had been raised under highly crowded conditions in mass-rearing facilities for ...

The cryptofauna are the small cryptic organisms that inhabit the interstices of coral colonies and have a great contribution to the biodiversity of the reef. Some of these species are vulnerable to environmental deterioration ...

Based on aroeira's (Myracrodruon urundeuva) antimicrobial activity and a future trend to compose intracanal medication, the aim of this study was to assess in vivo inflamatory tissue response to the extracts by edemogenic ...

A study of floral biology and the breeding system of Hamelia patens Jacq. (Rubiaceae) was carried out in northern India from March, 2005 to February, 2007. The data obtained was compared with those obtained from the original ...

The division of labor is the foundation of social organization in insects. Eusociality is mainly characterized by, in addition to other factors, the division of labor castes. One of the factors that determine the allocation ...
