| ABSTRACT: The habitat fragmentation modifies the pattern of animal activity. This study aimed to determine the activity pattern of frugivorous bat species in an urban forest fragment in southwestern Amazonia. The study was conducted from August 2013 to September 2014 with 10 mist nets (9m x 2.5m), opened at ground level throughout all the night and totaling 64,800 m².hour/net. Two hundred and sixty-one captures of bats from 28 species were recorded. The period with the highest capture rate and species of bats was the first period of the night (until 00:00). The species with the highest incidence of catches were, in ascending order, Carollia brevicauda (Schinz, 1821), Carollia perpicillata (Linnaeus, 1758), Artibeus planirostris (Spix, 1823), and Artibeus... |

| This study was conducted in the Cotriguaçu district, situated on the bank of the Juruena River, in Mato Grosso state. The collects were carried out from August 22 to 25, 2007 with chemical baits to attract male orchid bees. The bees were captured on a daily basis, from 8 a.m. to 12 p.m. Of the 89 males captured three belonged to Eufriesea pulchra Smith. Before the present study, E.pulchra had been reported in the states of Pará, Amazonas, Amapá, (dubiously) São Paulo, and Maranhão. This occurrence extends its geographical distribution range by 900 to 2,000 km southwards in South America, as it is now recorded in the Amazon and Platina basins. |

| The first capture of the phyllostomid bat Micronycteris homezi Pirlot, 1867 in Brazil is reported. An adult male was captured in a forest fragment in Alter do Chão, Santarám, Pará State, in May 7th , 1998. A description of the species, previously reported only in Venezuela and French Guiana, is given, as well as the measures of the captured specimen. After this report, the bat fauna of Brazil is composed by 139 species. |

| ABSTRACT Planicapritermes Emerson, 1949 is a South American termite genus with two nominal species: Planicapritermes planiceps (Emerson, 1925) and Planicapritermes longilabrum Constantino, 1998. The soldiers of this genus are characterized by strongly asymmetrical mandibles. Planicapritermes planiceps was described from soldiers and workers, and P. longilabrum only from soldiers. Here we describe and illustrate workers of P. longilabrum based on specimens collected in Rondônia state, Brazil. We also present a comparison between workers and soldiers of P. planiceps and P. longilabrum, and describe the nest of P. planiceps. |

| Leaves from 120 canopy trees and 60 understory tree saplings growing in primary and secondary forests near Manaus, Brazil, were collected for determination of standing levels of herbivory (percent leaf area lost). Overall, levels of herbivory on leaves of central Amazonian trees were low. About one quarter of the leaves examined (n = 855) had no damage at all. In most other Neotropical sites studied the mean percentage of herbivory was found to vary between 5.7 and 13.1%, whereas in Manaus it was only 3.1%. The data presented here support the contention that levels of herbivore damage are positively related to soil fertility. No significant difference was found in herbivory levels between canopy trees and understory saplings. Also, there was no difference... |

| A pollen morphology study of the Gentianaceae Juss. of Reserva Florestal Adolpho Ducke (Manaus, Brazil) was performed. The pollen grains of the studied species varied morphologically in their pollen units (tetrads or monads), size (small, medium and large), shape (oblate, suboblate, oblate spheroidal, spheroidal, prolate spheroidal and prolate), polarity (heteropolar, isopolar or subisopolar), symmetry (bilateral or radial) and number and type of aperture (3-colporate and 1-3porate). In relation to ornamentation, pollen grains had a sexine that was psilate in the Voyria species, microreticulate in Voyriella parviflora and reticulate heterobrochate in Tachia grandiflora and Irlbachia alata. The exine in I. alata showed great variability in the size and... |

| Despite its enormous area, diversity of habitat, and bat species, studies in the Brazilian Amazon represent just a small portion of the bat research in the South América. Consequently, the distribution of the major part of the bat species in the Brazilian Amazon remains incompletely documented. Conservation strategies involving bat species in the Brazilian Amazon may be difficult without more information about geographic distribution, status, roost, food preferences, and reproduction of the species. Here is presented an updated list of species of bats of Alter do Chão, and complete this list with data from the nearby Amazon National Park, providing a list of bats in the Santarém area. This list includes at least 55 species of bats, representing 34 genera,... |
