1. Phoretic mites (Rhinoseius spp.) in Apodiformes from Cerrado and Pantanal Biomes in midwestern Brazil
Resumo Os ácaros nasais são comumente encontrados em beija-flores (Apodiformes). Na maioria dos casos, os ácaros foram relatados como endoparasitas, parasitando o sistema respiratório, particularmente as câmaras nasais anteriores, a laringe, a traqueia, os pulmões e os sacos aéreos e conjuntivais. No entanto, alguns ácaros são transportados apenas p

2. Temporal distribution of fruit-feeding butterflies (Lepidoptera, Nymphalidae) in the eastern extreme of the Amazon region
RESUMO A pluviosidade é considerada um dos fatores mais determinantes na sazonalidade de insetos na região amazônica. No entanto, poucos estudos analisaram a dinâmica temporal de borboletas frugívoras na Amazônia brasileira, especialmente em sua porção oriental. Aqui, avaliamos os padrões de diversidade e a distribuição temporal de borboletas frug

3. BEHAVIOR OF PANTANEIRA AND GIROLANDO HEIFERS REARED ON PASTURES IN THE FOUR SEASONS OF THE YEAR
RESUMO O objetivo deste estudo foi avaliar a dinâmica alimentar e fisiológica de novilhas Pantaneira e Girolando criadas em pastagem e a preferência por três tipos de sombras naturais. Foram utilizados 14 animais, sete de cada raça, com peso médio de 328 kg (Pantaneira) e 430 kg (Girolando). O pasto consistia em Panicum maximum. Foi avaliado o comporta

4. Diet and resource sharing by two Pimelodidae species in a Southeastern Brazilian reservoir
Resumo: Os peixes podem variar suas dietas e dinâmicas alimentares de acordo com fatores bióticos e abióticos. O conhecimento insuficiente desses fatores em reservatórios limita o manejo dessas áreas. O objetivo deste estudo foi determinar a dieta de duas espécies de peixes aparentados e mais coletados; verificar a influência de fatores bióticos e ab

5. Seroprevalence and spatial distribution dynamics of Yersinia pestis antibodies in dogs and cats from plague foci in the State of Ceará, Northeastern Brazil
Abstract INTRODUCTION: In Brazil, the plague is established in several foci located mainly in the northeastern part of the country, where it alternates between active and quiescent periods. These foci in the State of Ceará have high epidemiological importance. In addition to other plague detection activities, plague areas can be monitored through serologi

6. Green turtle (Chelonia mydas) genetic diversity at Paranaguá Estuarine Complex feeding grounds in Brazil
Sea turtles are marine reptiles that undertake long migrations through their life, with limited information regarding juvenile stages. Feeding grounds (FGs), where they spend most of their lives, are composed by individuals from different natal origins, known as mixed stock populations. The aim of this study was to assess genetic composition, natal origins a

7. Spatial and temporal dynamics of drosophilid larval assemblages associated to fruits
The study of organisms and their resources is critical to further understanding population dynamics in space and time. Although drosophilids have been widely used as biological models, their relationship with breeding and feeding sites has received little attention. Here, we investigate drosophilids breeding in fruits in the Brazilian Savanna, in two contras

8. Effect of feeding frequency on the reproductive efficiency of two species of Triatoma with different epidemiological importance
Introduction In Triatominae, reproductive efficiency is an important factor influencing population dynamics, and a useful parameter in measuring a species' epidemiological significance as a vector of Trypanosoma cruzi (Chagas, 1909). The reproductive efficiency of triatomines is affected by food availability; hence, we measured and compared the effects of f

9. Is there an efficient trap or collection method for sampling Anopheles darlingi and other malaria vectors that can describe the essential parameters affecting transmission dynamics as effectively as human landing catches? - A Review
Distribution, abundance, feeding behaviour, host preference, parity status and human-biting and infection rates are among the medical entomological parameters evaluated when determining the vector capacity of mosquito species. To evaluate these parameters, mosquitoes must be collected using an appropriate method. Malaria is primarily transmitted by anthropop

10. Factors influencing the selection of communal roost sites by the Black Vulture Coragyps atratus (Aves: Cathartidae) in an urban area in Central Amazon
Increasing populations of the Black Vulture, Coragyps atratus (Bechstein, 1793) and the capacity this bird has to live near humans has resulted in vulture-human conflicts. These conflicts increase the need for the effective management of vultures. Improved understanding of communal roosting dynamics is a key aspect of vulture biology that provides informatio

11. Diet and reproductive dynamics of Trachelyopterus lucenai (Siluriformes: Auchenipteridae) in subtropical coastal lagoons in southern Brazil
This study analyzed the diet and reproductive dynamics of Trachelyopterus lucenai Bertoletti, Pezzi da Silva & Pereira, 1995, an allochthonous fish species in the subtropical coastal lagoons of the Tramandaí River, Rio Grande do Sul, Brazil. The fecundity of the species is described for the first time. Specimens were captured in the interconnected lagoons I

12. Ecophysiological responses to the effect of annual management on an endemic viviparous fish in central plateau of Mexico
Studies on the biological aspects of fish typically focus on species that currently have commercial value, causing species that lack such market value to be ignored. This is the case of several freshwater fish, specifically of several members of the Goodeidae family. In the State of Querétaro there are several species of this family characterized for being
