1. Biological characteristics of Meccus phyllosomus pallidipennis (Hemiptera: Reduviidae: Triatominae) fed on two different hosts
Abstract INTRODUCTION: Different blood meal sources can affect biology of triatomines. METHODS: We studied the influence of two different blood meal sources (rabbits and hens) on five biological parameters in Meccus phyllosomus pallidipennis and collected biological parameters. RESULTS: The cohort fed on rabbits had a shorter median life-cycle and lowe

2. Species boundary and extensive hybridization and introgression in Petunia
ABSTRACT Studying the role of hybridization in the speciation of plants is one of the most thrilling areas of evolutionary biology. Hybridization in natural populations can act in opposition to divergence, contribute to adaptation through introgression or foster the emergence of new lineages via hybrid speciation. Species of the plant genus Petunia grow in o

3. RNA viruses in trypanosomatid parasites: a historical overview
Viruses of trypanosomatids are now being extensively studied because of their diversity and the roles they play in flagellates’ biology. Among the most prominent examples are leishmaniaviruses implicated in pathogenesis of Leishmania parasites. Here, we present a historical overview of this field, starting with early reports of virus-like particles on elec

4. Morphological Diversity of Coleoptera (Arthropoda: Insecta) in Agriculture and Forest Systems
ABSTRACT Coleopterans (Coleoptera) are major ecosystem service providers. However ecomorphological features that are comparable in a wide range of invertebrates within this group and in various environments must be found, to be able to study regions with different species, contributing to overcome difficulties of the taxonomic approach and understand the fun

5. Growth and reproductive biology of the amphidromous shrimp Palaemon pandaliformis (Decapoda: Caridea) in a Neotropical river from northeastern Brazil
ABSTRACT Population biology, growth and reproductive aspects of the amphidromous shrimp Palaemon pandaliformis (Stimpson, 1871) were investigated in a Neotropical river of northeastern Brazil. The specimens were collected every month from September 2009 to August 2010. Total and monthly sex ratios deviated in favour of males. Von Bertalanffy growth parameter

6. Efectos del disturbio antrópico sobre las poblaciones de Leprolochus birabeni (Araneae, Zodariidae) en el Chaco Seco del noroeste de Argentina
Abstract Little is known about the biology and ecology of the myrmecophagic species Leprolochus birabeni Mello-Leitão, 1942 (Zodariidae), the only representative of this genus in Argentina. This species is typical of arid environments of the north of Argentina, and their study in the Chaco Seco is relevant, because is a highly disturbed ecoregion and one of

7. Systems biology approach to study the high altitude adaptation in tibetans
The aim of this work was to study an integrative systems biology research strategy to construct a network including the protein-protein interactions (PPIs) and microRNAs (miRNAs) and identify the functional biological processes and pathways for high-altitude adaptation in Tibetans. The pathway enrichment analysis revealed that the genes in the network were m

8. Behavioural biology of Chagas disease vectors
Many arthropod species have adopted vertebrate blood as their main food source. Blood is rich in nutrients and, except for the presence of parasites, sterile. However, this food source is not freely available, nor is obtaining it devoid of risk. It circulates inside vessels hidden underneath the skin of mobile hosts that are able to defend themselves and eve

9. A proposal towards resilient complex networks through evaluation and adaptation mechanisms
Attacks and failures tolerance of complex networks is related to the concept of vulnerability in different contexts, from biology and sociology to computer science and physics. Studies have revealed that the topologies of these networks are inherently vulnerable to failures of central elements. Complex adaptive systems, emergent in nature, are considered mor

10. Biologia térmica de Scaptotrigona depilis (Apidae, Meliponini): adaptações para lidar com altas temperaturas / Thermal biology of Scaptotrigona depilis (Apidae, Meliponini): adaptations to deal with high temperatures
O grande sucesso ecológico dos insetos sociais se deve, em grande parte, ao controle das condições climáticas do ninho, entre as quais é possível destacar a temperatura como uma das variáveis mais importantes. Nas abelhas sem ferrão, um grupo de abelhas eussociais com cerca de 400 espécies distribuidas pela região Neotropical, apesar dos poucos est

11. Efeito do exercicio incremental exaustivo nas metaloproteinases 2 e 9 no musculo gastrocnemio de ratos Wistar / Effect of exhaustive incremental exercise in metalloproteinases 2 and 9 in the gatrocnemius muscle of rats
Os músculos esqueléticos são constituídos por fibras musculares e pela matriz extracelular. Em resposta ao exercício, o músculo apresenta a habilidade de transformar o estresse mecânico da contração muscular em adaptações de cunho biológico, a esse processo deu-se o nome de mecanotransdução. Embora pouco se saiba sobre a importância da matriz

12. Diurnal variation of vascular diameter and reactivity in healthy young men
The higher incidence of cardiovascular events in the morning is accompanied by an increased vascular tone. However, there are few published studies designed to evaluate the diurnal variation of vascular and endothelial parameters in healthy subjects. In the present investigation, we evaluated the diurnal variation in brachial artery diameter (BAD), flow-medi
