Association between rainfall seasonality and the flowering of epiphytic plants in a Neotropical montane forest
(2017)
The association between the reproductive phenology of epiphytic communities with environmental and ecological factors remains largely unexplored. Because epiphytes depend on environmental moisture, seasonal changes in ...
Soil volumetric changes in natric soils caused by air entrapment following seasonal ponding and water table rises
(Elsevier Science, 2001-11)
Soil volumetric changes have been seldom studied in seasonally ponded soils subjected to periodic water table rises. In the Flooding Pampa of Argentina the topsoils develop significant swelling and shrinkage, despite their ...
Larval aggression is independent of food limitation in nurseries of a poison frog
(2016)
Aggression between nurserymates is common in animals and often hypothesized to result from proximate resource limita- tion. In numerous terrestrial frogs, larvae develop in phytotelmata, tiny water bodies where resources ...
Scaling up of leaf transpiration ans stomatal cinductance of two Eucalyptus grandis x Eucalyptus urophylla clone in response to environmental variables
(Ipef-inst Pesquisas Estudos FlorestaisPiracicabaBrasil, 2011)
Retrieval of Secchi disk depth from a reservoir using a semi-analytical scheme
(2017-09-01)
The mechanistic model reported in Lee et al. (2015) estimating the Secchi disk depth (ZSD) was applied to an oligo- to mesotrophic reservoir in Brazil. The model was originally validated with data covering lake, oceanic, ...
COMPETITION AMONG EUCALYPTUS TREES DEPENDS ON GENETIC VARIATION AND RESOURCE SUPPLY
(ECOLOGICAL SOC AMER, 2008)
Genetic variation and environmental heterogeneity fundamentally shape the interactions between plants of the same species. According to the resource partitioning hypothesis, competition between neighbors intensifies as ...
Leaving no stone unturned in light of the COVID-19 faecal-oral hypothesis? A water, sanitation and hygiene (WASH) perspective targeting low-income countries
The human coronavirus disease (COVID-19) is now a global pandemic. Social
distancing, hand hygiene and the use of personal protective equipment dominate the current fight
against COVID-19. In developing countries, the ...
Validation of a root water uptake model to estimate transpiration constraints
(ELSEVIER SCIENCE BV, 2010)
Experimental results obtained from a greenhouse trial with common bean (Phaseolus vulgaris L) plants performed to test model hypotheses regarding the onset of limiting hydraulic conditions and the shape of the transpiration ...
Decomposition of Eucalyptus grandis and Acacia mangium leaves and fine roots in tropical conditions did not meet the Home Field Advantage hypothesis
(2016-01-01)
Unlike Eucalyptus monocultures, nitrogen fixing trees are likely to improve the soil nutrient status through the decomposition of N-enriched litter. The Home Field Advantage (HFA) hypothesis states that plants can create ...
