Mistletoes have been studied in temperate countries regularly because they can be pests of cultivated plants and forest plantations. In comparison with habitats, little is known about the ecology mistletoes Neotropics. More emphasis should given to neotropical could important elements plant communities, acting as key resources for pollinators, seed dispersers herbivores. Using a combination findings from early mistletoe studies empirical evidence several recent case studies, we report...
ABSTRACT The aim was to evaluate the ingestive behavior and body development of backgrounded heifers from three genotypes in Brazilian Pantanal. Twenty‐two with an average weight 180 kg 15 months age were used, distributed into genotype groups: eight Nelore (N), seven × Angus (½ Angus, NA), Pantaneiro Pantaneiro, NP). NP exhibited similar grazing times, which higher compared NA heifers. It observed that chest depth, heart girth, rump width between ischia, hook ilia values among other...
We carried out a research on the Palicourea rigida (Rubiaceae) inflorescences, distylous shrub of Brazilian Cerrado. Our objective was to compare inflorescence architectural complexity and its quality in two floral morphs search for any relationship with spider occurrence. In order assess resources, we quantified nectar volume sugar concentration number fruits flowers (intact aborted) both without spiders. For heterogeneity, structures levels branching. Spider occurrence higher longistylous...
The database of the Brazilian Program for Biodiversity Research (PPBio; GIVD ID SA-BR-001) includes data on environment and biological groups such as plants.It is organized by site, which usually a grid with 10 to 72 uniformly-distributed plots, has already surveyed 1,638 relevés across different ecosystems.The sampling design based RAPELD system allow integration from diverse taxa ecosystem processes.RAPELD spatially-explicit scheme monitor biodiversity in long-term ecological research...
Aquatic macrophytes have properties and mechanisms which are useful for the removal of substances in solution, commonly used phytoremediation processes aquatic environments. This study evaluated performance copper (Cu) accumulation by Salvinia biloba Raddi (Salviniaceae) different metal concentrations (1, 3 5 µg mL-1), as well control treatment, measured at intervals 0, 7 14 days under laboratory conditions, with to pH luminosity. After experiment, S. biomass was washed, kiln dried, crushed...
Mistletoes are aerial hemiparasitic plants which occupy patches of favorable habitat (host trees) surrounded by unfavorable and may be possibly modeled as a metapopulation. A metapopulation is defined subdivided population that persists due to the balance between colonization extinction in discrete patches. Our aim was evaluate dynamics mistletoe Psittacanthus robustus its host Vochysia thyrsoidea three Brazilian savanna areas using approach. We also evaluated how differences terms fire...
The Brazilian Pantanal is an extensive wetland with heterogeneous habitats, primarily due to the river-floodplain system and plants differential adaptations reproductive strategies. Factors such as altitude, distance among plant formations, flood pulse must be considered better understand its diversity. Aiming assess influence of biogeographic patterns in this system, we analyzed floristic composition six areas along Paraguay River, including residual relieves, verifying pattern similarity,...
Abstract In seasonally flooded wetlands, inundation and associated organic debris deposition followed by a drawdown period can promote plant community diversity across space time. Post‐flood regeneration might be influenced the direct effect of flooding on seed dispersal seedling emergence, as well indirect trapping germination. Our objective was to examine influence seasonal flooding, topography, cover distribution in grassland. We measured species richness, abundance, for 3 yr grassland...
In the tropics, studies on ecology of host-parasite interactions are incipient and generally related to taxonomic aspects. The main objective present work was analyze ecological aspects identify metazoan fauna ectoparasites that infest piranha, Pygocentrus nattereri. May 2002, field samples were collected in rio Araguaia basin, State Goiás (Brazil). A total 252 individuals P. nattereri caught with fishhooks 32.14% infested ectoparasite crustaceans. recorded branchiurans, Argulus sp. Dolops...
Abstract The breathing behavior of the jeju fish H oplerythrinus unitaeniatus has been focus several studies in recent decades. Few these studies, however, have described how fish's air functions natural environments. We examined changes . during daily variations dissolved‐oxygen (DO) content water Amazonian streams. recorded mean time intervals between instances when breached surface to take atmospheric and variation DO concentrations. also observed number individual that together as well...
Modeling clays have been used in several ecological experiments and proved to be an important tool variables control. The objective of our study was determine if fruit color isolated grouped displays influences the selection by birds field using artificial fruits. Data were collected six plots distributed homogeneously 3 km long trails with a minimum distance 0.5 km. We paired experimental design establish experiments, so that all treatments available local bird community each plot. Overall,...
Floating litter banks are an ephemeral habitat consisting of branches, twigs, flowers, seeds, and fruits that trapped on the stream water surface by a variety retention mechanisms. These heterogeneous materials form deep layer dead plant matter is colonized organisms, including fish forage aquatic macroinvertebrates found in this unique habitat. In study, we aimed to characterize which species occupy floating their trophic characteristics, as well determine if assemblage composition richness...
Initiatives directed at managing information on aquatic plants can support different areas of scientific research, educational practices and political decisions for sustainable management protection wetlands natural resources, as well reveal knowledge gaps regarding wetlands. Furthermore, such initiatives contribute directly to consolidating wetland classification systems in Brazil. The objectives this work are present explore the use a data repository online platform created specifically...
The input of particulate and dissolved organic matter (POM DOM, respectively) from terrestrial ecosystem drainage basins is an important energy nutrient source in limnic food chains. Studies indicated that semi-deciduous seasonal forests located areas Brazil have the potential to produce 7.5 - 10.3 Mg ha−1/year POM. global increase vegetation destruction, such as forests, threatens this allochthonous resource can significant impacts on river lake communities Therefore, it critical...
Mistletoe can have a major impact on the fitness of host plant. If there is more than one species mistletoe same tree, overall might be amplified. We report occurrence tree. Although it not rule in field, to our knowledge, been no studies this topic. In most cases, two were recorded although we three occasion. This demonstrates that different compatible with species. Therefore, compatibility (structural and physiological) an important factor for mistletoe. Recent shown if does "recognize"...
