1. Efficiency of trap nests in attracting stingless bees in the central Brazilian Amazon
RESUMO A obtenção de colônias de abelhas sem ferrão na natureza, para a formação ou ampliação de meliponários e outras finalidades, é permitida por lei no Brasil usando recipientes-isca ou ninho-isca, ou outros métodos não destrutivos. Nós testamos a eficiência do ninho-isca feito de garrafa plástica para atração e nidificação de abelhas s

2. Constrictotermes cyphergaster (Blattaria, Termitidae) termite nests as substrates for lichen fixation in the semiarid region of northeastern Brazil
RESUMO Sementes de sabiá (Mimosa caesalpiniifolia Benth.) apresentam dormência tegumentar, dificultando a absorção de água e oxigênio, consequentemente retardando a germinação. Dessa forma, objetivou-se avaliar métodos para superação de dormência associados ao condicionamento fisiológico sobre germinação e vigor de sementes de sabiá, consider

3. Pollen sources used by Frieseomelitta Ihering 1912 (Hymenoptera: Apidae: Meliponini) bees along the course of the Rio Negro, Amazonas, Brazil
ABSTRACT Insect pollination has influenced the evolution and diversification of angiosperms. Consequently, knowing plants used as food sources by bees, the most important pollinator group, is the first step toward understanding how their ecological relationships works. Pollen source information is also highly relevant for bee management and associated fruit

4. Dermatoscopy of the Borst-Jadassohn phenomenon in hidroacanthoma simplex,
Abstract The Borst-Jadassohn phenomenon is a morphological finding that consists of the presence of well-defined nests of cells located in the spiny stratum of an acanthotic epidermis. One of the neoplasms where this phenomenon is found is hidroacanthoma simplex. This neoplasm is considered the intraepidermal form of the eccrine poroma. Despite its benign na

5. The effects of two abundant ant species on soil nutrients and seedling recruitment in Brazilian Atlantic Forest
ABSTRACT Ants can influence soil fertility and the spatial distribution of seeds, with possible effects on seedling recruitment. The ant species Pachycondyla striata Fr. Smith, 1858 and Odontomachus chelifer (Latreille, 1802) co-occur in many forest areas in the Neotropics. We assessed soil fertility and seed bank structure in soil samples close and distant

6. Chemical control of leaf-cutting ants: how do workers disperse toxic bait fragments onto fungus garden?
ABSTRACT Leaf-cutting ants are controlled with toxic baits. For the method’s greater efficiency, the baits must be distributed and processed by workers during fungus cultivation. To test hypotheses whether the mode of action of the active ingredients, which blocks the sodium channels and interrupts the production of ATP in the mitochondria, interferes with

7. Solution Inhibitory of Ant Nest (Myrmecodia Pendans) Extract on the Formation of Plaque in Children with Early Childhood Caries
Abstract Objective: To evaluate the effectiveness of gargling the solution of ant nest extract against plaque formation in children who experience Early Childhood Caries (ECC) when used as a mouthwash. Material and Methods: This study uses a pretest-posttest design with a control group. Thirty children with ECC, which were divided into three groups, namely

10. Native and ornamental exotic resources in pollen loads and garbage pellets of four stingless bees (Apidae, Meliponini) in an urban environment with riparian native forest
Abstract: An entomopalynological study to assess pollen use by wild bees was performed in an urban environment with riparian native forest in the Chaco region of Argentina. A combined method for sampling pollen loads and garbage pellets at nest entrances in four stingless bees with different entrance size and forager traffic was here successfully used. Samp

11. Ameloblastic carcinoma arising from a preexistent ameloblastoma
RESUMO O carcinoma ameloblástico (CA) é um tumor odontogênico raro que representa o equivalente maligno de um ameloblastoma. Existem poucos casos de CA na literatura em inglês: nos últimos 10 anos, foram relatados apenas 16 casos surgidos de ameloblastomas preexistentes. Múltiplas recorrências locais desse tumor precedem essa transformação. Neste re
