An evergreen neotropical savanna tree (Gochnatia polymorpha, Asteraceae) produces different dry- and wet-season leaf types

Gochnatia polymorpha (Less.) Cabrera is a widespread tree species found in different physiognomies of neotropical savanna (cerrado) formations of south-eastern Brazil. The present study describes some leaf anatomical characteristics of this species as a function of the time of leaf flush, during dry or wet seasons. This species presents anatomical plasticity in the cuticle, palisade parenchyma and abaxial epidermis as well as in stomatal size and stomatal and trichome density, which are leaf structures linked with water-status control. Leaf structure changed to suit the particular environmental conditions during dry and wet seasons. The production of different wet-and dry-season leaf types in G. polymorpha could be a response to drought and an adaptation to environmental constraints in the cerrado.

Intestinal protozoan parasites with zoonotic potential in birds

The aim of this study was to evaluate the occurrence of potentially zoonotic intestinal protozoan infections in exotic and wildlife Brazilian birds. Fecal samples from 207 birds of 45 species were examined. Infections by Balantidium sp., Entamoeba sp., and Blastocystis sp. were observed in 17 individuals (8.2%) of Gnorimopsar chopi, Oryzoborus angolensis, Sporophila caerulescens, Ramphastos toco, Aratinga leucophtalmus, and Pavo cristatus.
