The aim of this study was to quantify the genetic variances among provenances and progenies of Pinus caribaea var. hondurensis to increase the wood productivity in northwestern of Paraná State, Brazil. The trial was established with seed from Guatemala and Honduras, in a randomized complete block...

The present work consisted of presenting some of the main results about the use of taper models in different native and exotic species, except for pinus and Eucalyptus, in the different regions of Brazil. Many works were carried out, mainly, in the South, North, Southeast and Center-West....

New World Nonhuman Primates are highly susceptible to clinical toxoplasmosis. Serum samples from 126 recently captured Leontopithecus chrysomelas, from an exotic and invasive population, were tested for Toxoplasma gondii antibodies by the modified agglutination test (MAT, cut-off 1:25); all were...

Brazil has a wide diversity of exotic birds that were brought to this country during the European colonization. These animals are kept in captivity and, in some cases, in inadequate facilities, which may facilitate the introduction of pathogens, including gastrointestinal parasites. The purpose of...

Due to its cosmopolitan and invasive characteristics, the Mediterranean fruit fly, Ceratitis capitata (Wied.), is considered to be the most harmful tephritide to global fruit farming, causing greater losses in production than any other species of the same family. In Brazil, it was first detected in ...

Invasive exotic species cause adverse changes in vegetal communities where they are established, leading the invaded areas to a lower ecological condition, with the loss of the biodiversity at the species and several ecological processes level. Based upon this finding, this research aimed to...

Germination, floristic composition and phytosociology in the soil weed seed bank are important to know the weed flora and to predict weed infestations. The objective of this research was to assess and to compare germination, the weed flora and phytosociology of the soil weed seed bank in rice...

There are few studies on the effects of fire on the seasonal semideciduous forest of the Cerrado region. This study aimed to assess the effect of fire on Semideciduous forest fragments located in the Altamiro Moura Pacheco State Park (AMPSP). The study area is located in the central state of Goiás. ...

The objective of this study is to describe and systematize the middle cerebral artery at the brain surface of the turtle (Trachemys scripta elegans), determining a standard model of irrigation and the main ramifications and territory, in this species. 30 turtles received pre-anesthetic medication...

This study records the occurrence of eucoilines (Hymenoptera: Figitidae), parasitoids of the African fig fly Zaprionus indianus Gupta (Diptera: Drosophilidae), in the Brazilian semi-arid Caatinga biome. We obtained from mango (Mangifera indica L.) and guava (Psidium guajava L.) fruits Drosophilidae ...
