Abstract The consequences of introducing Cichla cf. monoculus Spix & Agassiz, Astronotus ocellatus (Agassiz) and Pygocentrus nattereri Kner into lakes in the River Doce basin, Brazil, on richness, diversity efficiency aquatic macrophytes as natural refugia to native fishes was investigated. Samples were taken from with without alien areas macrophytes. presence reduced richness fish community. function, which could be attributed clustering macrophytes, does not exist these probably...
ABSTRACT The vicinity of natural areas can enhance availability pollinators and crop productivity. Considering the global reduction food insecurity, innovative strategies to pollination yield are important. Thus, we investigated efficacy using colored attractors improve okra yield. use pollinator led a significant increase in length, volume, weight comparison plants without attractors, notably larger when compared access. Although uncertainties remain regarding scalability optimal...
Odonate species are classified in terms of their thermoregulatory behavior into flier and percher categories. Larger perchers could be more efficient thermoregulators sunny sites smaller depend on air temperature. In this paper, an analysis the behavioral temporal budget odonate neotropical assemblage was performed to determine role body size territorial defense general strategies. This revealed three groups based time budget. The first second contained that remained perched for most...
Odonate larvae are important components of aquatic environments in tropical areas. They also develop aquaculture ponds, where they can cause economic losses. In this study, we have tried to describe the general community patterns ponds Viçosa, south-eastern Brazil. Our aim is evaluate how environmental and bionomic factors determine their composition species richness. We identified two groups (plants bottom-dwellers) based on larval microhabitat preferences. Vegetation determines occurrence...
The present study shows the distribution of alien fish species in tropical lakes middle Doce river basin, southeastern Brazil, obtained from a rapid assessment program. causes for their introductions were sportfishing improvement some specific and aquaculture studied basin. Presently, these have wide occurring 41 54 studied, representing an actual threat to regional native community. natural connection among streams during rainy season dispersal mediated by local people are main invasion...

The lakes in the middle rio Doce Valley (MG) are suffering impacts due to introduction of invasive fish species, mainly piscivorous species like red piranha Pygocentrus nattereri and peacock bass Cichla kelberi. Fishes were collected bimonthly samples conducted at ten along a year. present study showed that composition native assemblages is significantly related presence type non-native species. Fish distribution among can be explained by differences body size: smaller less concentrated with...
The Carangola River is one of the main components river Muriaé, which major tributary lower Paraíba do Sul. In present study, sampling was carried out every three months during year in sites situated upstream town (Minas Gerais state, Brazil) and downstream. Twenty fish species, belonging to 17 genera 12 families, were found — fifteen species 13 downstream town. Diversity estimates (Shannon inverse Berger-Parker indices), based on biomass abundance, as well physical-chemical parameters...
Herbivorous insects may attack eucalyptus causing economic losses.One of these pests is the moth Euselasia apisaon Dahman, a key pest in basin middle Rio Doce.Here we studied survival pupae this Eucalypts and understorey plants tested hypotheses: i) live are more abundant than eucalyptus, ii) there no difference between abundance different understorey.We sampled three areas cultivated with Belo Oriente, MG, samples were taken five plots each area, getting branches plant trees that bordered...
The economic exploration of pear in the subtropical areas is possible when using hybrid cultivars obtained by crossing European (Pyrus communis) and Asian pyrifolia). Genetic improvement programs Brazil have launched some recent decades. Pear requires cross-pollination to improve fruit set commercial plantations. In case these trees, combinations pollen receptor donor that are best for cultivation regions not known. objective this study was select with potential be pollinators trees regions....
Abstract: Aim Assessing the damage caused to natural environments and native biodiversity by alien species is challenging. We tested whether number of detections affected total or invader richness, considering importance predicting which are more probable future invaders. Methods summarized a research information survey conducted on amphibians, annelids, aquatic macrophytes, cnidarians, crustaceans, fish, microorganisms, mollusks, nemathelminths, platyhelminths, reptiles, for Brazilian...
The importance of water resources to mankind and the threat level these have withstood due regional worldwide human intervention are undeniable. In middle stretch Doce river basin, there close 170 natural lakes, located between an environmental conservation area monoculture eucalyptus plantations, with social, economic biological importance. Our objective was evaluate whether surface in lakes has remained constant last few decades, make inferences on result. To that end, we measured 16 from...
Abstract Although West Indian Cherry (WIC) trees have abundant flowering, specimens of this species low fructification rates, potentially associated with the dependence these plants on pollinators for cross‐pollination and fruit production. We quantified rates assessed market value pollination services by conducting an experiment six treatments, including manual open pollination, pollinator exclusion treatment, blue yellow attractants. The investigation occurred at two sampling periods...
