1. Ant fauna associated with Microgramma squamulosa (Kaulf.) de la Sota (Polypodiaceae) fern galls
Abstract Galls are neoformed plant structures created by cell hyperplasia and hypertrophy induced by a number of organisms, especially insects. After adult insects hatch, senescent galls may remain on the host plant and be occupied by a succession of fauna, the most important and dominant being ants. This study aimed at characterizing the ant fauna successor

2. Presumed domatia are actually extrafloral nectaries on leaves of Anacardium humile (Anacardiaceae)
Supostas domácias foliares de Anacardium humile (Anacardiaceae) são na realidade nectários extraflorais - Anacardium humile , uma espécie do cerrado brasileiro, está associada a formigas forrageadoras, o que leva à descrição da estrutura presente em suas folhas como domácias. No entanto, as formigas coletam a secreção das folhas, um fenômeno que

3. Evolução de acarodomácias em Bignonieae (Bignoniaceae) / Evolution of acarodomatia in Bignonieae (Bignoniaceae)
Acarodomatia (or leaf domatia) are cavities or hair tufts found on the axils of veins on the abaxial surface of leaves. Several species of woody angiosperms mediate a mutualism with benefic mites (fungivorous and predaceous) through these structures. In this symbiotic relation, the leaf domatia provide refuge and protection to mites against natural enemies a

4. Estudos taxonomicos em Matayba Aubl. sect. Matayba (Sapindaceae) / Taxonomic studies in Matayba Aubl. sect. Matayba (Sapindaceae)
Sapindaceae presents about 140 genera and approximately 1600 species in Brazil is represented by 24 genera and about 400 species. Matayba Aubl. counts with 56 species being bushes or trees, distributed from Mexico to the north of Argentina and in Brazil 26 species are referred for several plant formations including the savannahs, campos rupestres, sandbank f

5. Constitutive defence mechanisms among species of Capsicum pepper and their importance in managing the broad mite Polyphagotarsonemus latus (Banks, 1904) (Acari: Tarsonemidae) / Mecanismos de defesa constitutiva em espécies de pimenta Capsicum e sua importância no manejo do ácaro branco Polyphagotarsonemus latus (Banks, 1904) (Acari: Tarsonemidae)
Several plant species belonging to the same genus can have very different leaf, flower, and fruit traits, which often determine the occurrence, abundance, and diversity of organisms living on the plants. Leaves of Capsicum pepper plants vary considerably and range from trichome-covered to glabrous leaves. Polyphagotarsonemus latus (Acari: Tarsonemidae) is th

6. Anatomical studies of Forsteronia G.Mey. (Apocynaceae) species of cerrado / Estudos anatomicos em especies de Forsteronia G.Mey. (Apocynaceae) de cerrado
The leaf anatomy of four cerrado species of Forsteronia was investigated in order to determine characters that could help to identify individuals collected in vegetative stage. Eleven characters, two macromorphological and nine anatomical, were surveyed and are useful to differ F. australis from F. glabrescens and F. pubescens from F. thyrsoidea. Domatia and

7. Ecology of Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae) on coffee plantations in the State of São Paulo / Ecologia do ácaro da mancha-anular (Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae) em cafeeiros no estado de São Paulo
The knowledge on the interactions among Brevipalpus phoenicis (Geijskes), other phytophagous or predaceous mites and coffee plants is still insufficient to establish an adequate management program for this crop, in order to minimize the problems caused by coffee ringspot virus (CoRSV), transmitted by B. phoenicis. In spite of the problem, little is known on

8. Plant lock and ant key: pairwise coevolution of an exclusion filter in an ant-plant mutualism.
Although observations suggest pairwise coevolution in specific ant-plant symbioses, coevolutionary processes have rarely been demonstrated. We report on, what is to the authors' knowledge, the strongest evidence yet for reciprocal adaptation of morphological characters in a species-specific ant-plant mutualism. The plant character is the prostoma, which is a
