Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain underst...

Why Do Agroforestry Systems Enhance Biodiversity? Evidence From Habitat Amount ...

Considering the present ecological crisis, land use-biodiversity relationships have become a major topic in landscape planning, ecosystem management and ecological restoration. In this scope, consistent patterns of outstanding biodiversity have been identified in agroforestry systems within diverse biogeographic regions and types of management. Empirical work has revealed that agroforestry higher structural com...

Ethnoentomological knowledge of the inhabitants of the municipality of Buriticu...

Insects play vital roles in the ecosystems where they occur but are often perceived negatively by humans. This perception is within the domain of ethnoentomology that, in general, has contributed to uniting scientific and traditional knowledge. The objective of this study was to evaluate the perception the population of the municipality of Buriticupu, Maranhão, has on insects. One hundred and seven residents we...

Soil beetles assemblages as ecological indicators in the neotropics: implicatio...

Emerging concerns with environmental issues has led researchers to look for indicators capable of providing information on the condition of ecosystems. Several animal species have been used for this role. Among these organisms, ground-beetles were found to be appropriate indicators, since they are adapted to all terrestrial habitats, being associated with ecosystem function and sensitive to ongoing changes. Sev...

Are litterfall and litter decomposition processes indicators of forest regenera...

Litterfall plays an important role in nutrient cycling and maintenance of soil fertility in terrestrial ecosystems. We gauged the effects of anthropogenic impacts on the production, decomposition and seasonality of litterfall in primary and secondary forests within a tropical landscape of the Brazilian Amazon. We hypothesized that leaf litter quantity and quality would differ in line with forest disturbance and...

Are Small Dung Beetles (Aphodiinae) useful for monitoring neotropical forests’ ...

Neotropical forests are extremely diverse ecosystems, listed within the biological hotspots of our planet. However, species from these forests are threatened by diverse anthropogenic activities. Small dung beetles (Scarabaeidae, Aphodiinae) assemblages were studied within different habitats of the Brazilian Amazon. The monitored habitats encompassed the main gradients of disturbance, from pristine to highly ant...

How informative is the response of Ground Beetles' (Coleoptera: Carabidae) asse...

Ground Beetles (Carabidae) have been suggested to be used as indicators of ecological status under the effects of anthropogenic land use and land cover changes in highly biodiverse regions such as the Neotropics. In this study Ground Beetles' assemblages from a region in the Brazilian Amazon were investigated for evaluating their applicability as disturbance indicators. Differences in assemblages between ecosys...

Does the composition of Scarabaeidae (Coleoptera) communities reflect the exten...

Attraction of Scarabaeinae (Coleoptera: Scarabaeidae) to different baits in the...

Dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) are considered essential for enhancing the physicochemical characteristics of soils, principally by changing organic materials (e.g. dead animals, faeces, fruits e leaf litter). This study compared the species richness and abundance of dung beetles captured using various types of baits, to demonstrate attractiveness differences in variable habitats of the Br...

Ethnobotanical survey of medicinal plants marketed in the municipality of Uruar...

The present study aimed to perform an ethnobotanical survey of medicinal plants marketed by the population of the municipality of Uruará, Pará, and its main districts. The respondents mentioned 63 species distributed in 36 botanical families. The most representative families were Lamiaceae, Asteraceae, Fabaceae and Rutaceae. The species with the highest Use Value were capim cidreira (Cymbopogon citratus, UV = 0...
