1. Predation on microcrustaceans in evidence: the role of chaoborid larvae and fish in two shallow and small Neotropical reservoirs
This study was focused on the predation upon microcrustaceans by an invertebrate predator (chaoborid larvae), and vertebrate predators (fish), in two small reservoirs in southeastern Brazil, with and without macrophytes, in two climatic periods (dry and rainy seasons). Chaoborus larvae were sampled in the limnetic zone, as they are scarce in the littoral, an

2. Anti-predator defense mechanisms in larvae of the butterfly Methona themisto (Nymphalidae: Ithomiinae) / Mecanismos de defesa contra predadores em larvas da borboleta Methona themisto (Nymphalidae: Ithomiinae)
Chemical defense in Lepidoptera involves several mechanisms such as sequestration of secondary metabolismcompounds of host plants and de novo synthesis of compounds that can provide some unpalatability or toxicity. The larvae of the butterfly Methona themisto (Nymphalidae: Ithomiinae) have a conspicuous coloration and feed exclusively on Brunfelsia uniflora

3. Efeitos da presenÃa de predadores sobre Ceriodaphnia cornuta (Sars, 1886) (Crustacea, Cladocera) em condiÃÃes de laboratÃrio / Effects of predator presence in CERIODAPHNIA CORNUTA (Sars, 1886)(Crustacea, Cladocera) in laboratory conditions
O objetivo deste trabalho foi testar o efeito da presenÃa de predadores vertebrados e invertebrados sobre Ceriodaphnia cornuta, em nÃvel de ciclomorfoses, e dinÃmica populacional (densidades, taxas de fecundidade, percentual de juvenis, presenÃa de machos, produÃÃo de efÃpios, etc.). Foram realizados quatro experimentos para a observaÃÃo dos efeitos

4. Alcaloides pirrolizidinicos utilizados por insetos na defesa quimica contra predadores vertebrados e invertebrados
Pyrrolizidine Alkaloids (PAs) are secondary plant compounds with a unique role in the interaction between plants, herbivorous insects, and their natural enemies relationships. The chemical defense due to PAs in Arctiidae moths and butterflies of sub-families Danainae and Ithomiinae (Nymphalidae) has been investigated with regards to vertebrate and invertebra
