13. Atlas of Mexican Triatominae (Reduviidae: Hemiptera) and vector transmission of Chagas disease
Chagas disease is one of the most important yet neglected parasitic diseases in Mexico and is transmitted by Triatominae. Nineteen of the 31 Mexican triatomine species have been consistently found to invade human houses and all have been found to be naturally infected with Trypanosoma cruzi. The present paper aims to produce a state-of-knowledge atlas of Mex

14. Feeding ecology of stream-dwelling Characidae (Osteichthyes: Characiformes) from the upper Tocantins River, Brazil
In this contribution we studied the trophic ecology of four Characidae species from the Cavalo Stream, upper Tocantins River, considering diet overlap and trophic niche breadth. The diet of the four species was composed of adult and immature insects, both autochthonous and allochthonous in origin. Autochthonous items dominated the diet of Moenkhausia dichrou

15. Distribution of the cladoceran Bosmina huaronensis Delachaux, 1918 and niche differentiation among populations from different biogeographic regions
Described from a high-altitude lake in Peru, Bosmina huaronensis Delachaux, 1918 has been recorded in diverse kinds of water bodies in South and North America, suggesting that this species has high environmental tolerance and a wide niche breadth. The present study surveyed the occurrence records of B. huaronensis from 55 localities and, using multivariate a

16. Diet and niche breadth and overlap in fish communities within the area affected by an Amazonian reservoir (Amapá, Brazil)
Nós investigamos a amplitude e a sobreposição de nicho de espécies de peixes que ocorrem em quatro ambientes afetados pelo reservatório Coaracy Nunes, no Estado brasileiro do Amapá. Amostras sazonais de peixes foram coletadas usando uma configuração padrão com malhadeiras, tarrafas, linhas e armadilhas. Quinhentos e quarenta conteúdos estomacais, r

17. Hatching and larval export of the intertidal crab Neohelice granulata in Mar Chiquita coastal lagoon, Argentina
Synchronization in the events of the reproductive cycle in female Neohelice granulata Dana, 1851 were studied from samples taken weekly and biweekly from September to December 2006 in the Laguna Mar Chiquita. The timing and larval hatching and synchronicity were inferred from numbers of ovigerous females and observing the stages of embryonic development. Syn

18. Dung beetle assemblages (Coleoptera, Scarabaeinae) in Atlantic forest fragments in southern Brazil
Dung beetle assemblages (Coleoptera, Scarabaeinae) in Atlantic forest fragments in southern Brazil. The beetles of the subfamily Scarabaeinae are important organisms that participate in the cycle of decomposition, especially in tropical ecosystems. Most species feed on feces (dung) or carcasses (carrion) and are associated with animals that produce their foo

19. Fish diet composition in permanent and semi-permanent pools in tropical wetlands of the Yucatan Peninsula
We compared fish diet composition between permanent (P) and semi-permanent (SP) pools in Petenes Biosphere Reserve (PBR), Campeche. A total of 445 gut contents were examined to determine stomach relative fullness (RF), fish diet as index of niche breadth (INB) and diet overlap. In SP pools, species showed a RF of 1.66 (57.20 % empty stomachs) whereas in P po

20. Verificação de framework conceitual de avaliação do desempenho de equipes-cliente: investigação a partir da construção de mapas cognitivos de profissionais de TI atuantes em projetos de implantação ERP
With high degree of breadth on the organisation and interdependence with its processes, the deployment of integrated management systems (ERP Enterprise Resource Planning) is not a simple task. Project management failures, unmet expectations, lengthy deployment deadlines and costs that reach up to five times the value of product licensing itself are among the

21. Children of time: the extended synthesis and major metaphors of evolution
It is time for an expansion and enrichment of evolutionary theory. The "back to the future" proposal contained herein is based on three postulates: 1) Neo-Darwinism is too impoverished for this task; 2) its predecessor, Darwinism, contained the necessary breadth of vision and metaphor to be the basis for an inclusive and unifying theory of biology; and 3) th

22. Microbial diversity in Brazilian mangrove sediments: a mini review
The importance and protection of mangrove ecosystems has been recognized in Brazilian Federal law since 1965. Being protected in law, however, has not always guaranteed their protection in practice. Mangroves are found in coastal and estuarine locations, which are prime real estate for the growth of cities, ports and other economic activities important for B

23. Diet and trophic niche of Lithobates catesbeianus (Amphibia: Anura)
Lithobates catesbeianus (Shaw, 1802) is an invasive anuran introduced in Brazil that is associated with the displacement and the decline of populations of native species worldwide. There is evidence that biological invasions are facilitated by certain attributes of the invading species, for instance niche breath, and that invasive species have a broader ecol

24. Food niche overlap between two sympatric leaf-litter frog species from Central Amazonia
We studied the feeding habits and similarities in the diet of two sympatric and syntopic Amazonian frog species, Anomaloglossus stepheni (Aromobatidae) and Leptodactylus andreae (Leptodactylidae) in a forested area in Central Amazonia. The breadth of the trophic niche of these species was 5.89 and 3.75, respectively, and approximately 85% of their diets were
