Aluminum prevents stomatal conductance from responding to vapor pressure deficit in Citrus limonia
Silva, Giselle Schwab
; Gavassi, Marina Alves ; Nogueira, Matheus Armelin ; Habermann, Gustavo (Environmental and Experimental Botany, 2018) [Artigo]
Stomatal aperture generally increases in response to low vapor pressure deficit (VPD) and decreases at high VPD. Aluminum (Al) inhibits root growth, indirectly exposing the roots to low water availability, which may decrease ... -
Rethinking tropical phenology: insights from long-term monitoring and novel analytical methods
Morellato, Leonor Patricia Cerdeira; ; Mendoza, Irene (Biotropica, 2018) [Artigo]
Here, we introduce the Special Section (SS) on long-term monitoring and new analytical methods in tropical phenology. The SS puts together nine original papers plus a synthesis, bringing significant advances and new insights ... -
Current issues in tropical phenology: a synthesis
; ; ; Mendoza, Irene; Morellato, Leonor Patricia C. (Biotropica, 2018) [Resenha]
We retrace the development of tropical phenology research, compare temperate phenology study to that in the tropics and highlight the advances currently being made in this flourishing discipline. The synthesis draws attention ... -
Leafing patterns and leaf exchange strategies of a cerrado woody community
de Camargo, Maria Gabriela Gutierrez; de Carvalho, Gustavo Henrique ; Alberton, Bruna de Costa ; Reys, Paula ; Morellato, Leonor Patrícia Cerdeira (Biotropica, 2018) [Artigo]
The deciduousness of tropical trees and communities depend on ecosystems characteristics such as plant species diversity, and strength of the dry season. Based on seven years of phenological observations, we provide the ... -
Multivariate cyclical data visualization using radial visual rhythms: A case study in phenology analysis
; Staggemeier, Vanessa G.; Morellato, Leonor Patricia Cerdeira ; (Ecological Informatics, 2018) [Artigo]
Phenology is a traditional science that investigates the periodic phenomena of plants and animals and their relations to environmental conditions. Typically plant phenological studies are based on observations made by ... -
Modularity, pollination systems, and interaction turnover in plant-pollinator networks across space
Carstensen, Daniel W.; ; Morellato, Leonor Patricia C. (Ecology, 2016) [Artigo]
Mutualistic interaction networks have been shown to be structurally conserved over space and time while pairwise interactions show high variability. In such networks, modularity is the division of species into compartments, ... -
Timing of seed dispersal and seed dormancy in Brazilian savanna: Two solutions to face seasonality
Escobar, Diego F.E; ; Morellato, Leonor Patricia C (Annals of Botany, 2018) [Artigo]
Background and Aims The relationship between fruiting phenology and seed dispersal syndrome is widely recognized; however, the interaction of dormancy classes and plant life-history traits in relation to fruiting phenology ... -
Change frequency heatmaps for temporal multivariate phenological data analysis
; Soares, Natalia Costa; Morellato, Leonor Patricia Cerdeira ; (Proceedings - 13th IEEE International Conference on eScience, eScience 2017, 2017) [Trabalho apresentado em evento]
The huge amount of multivariate temporal data that has been produced in several applications demands the creation of appropriate tools for the analysis and pattern characterization of change. This paper introduces a novel ... -
Persistence of submerged macrophytes in a drying world: Unravelling the timing and the environmental drivers to produce drought-resistant propagules
; Morellato, Leonor Patrícia C.; (Aquatic Conservation: Marine and Freshwater Ecosystems, 2018) [Artigo]
Under a warming scenario many permanent inland water bodies in the Mediterranean region have become temporary ones, so the persistence of submerged macrophytes depends on the timely production of drought-resistant propagules. ... -
Reproductive phenology of two co-occurring Neotropical mountain grasslands
Le Stradic, Soizig; ; ; Morellato, Leonor P. C. (Journal of Vegetation Science, 2018) [Artigo]
Aim: Climate tends to explain phenological variations in tropical ecosystems. However, water availability and nutrient content in soil strongly affect plant communities, especially those on old, climatically buffered, ... -
Does the major aluminium-resistance gene in wheat, TaALMT1, also confer tolerance to alkaline soils?
Silva, Carolina M. S.; ; Habermann, Gustavo ; ; (Plant and Soil, 2018) [Artigo]
Aim: A major limitation to plant growth in acid soils is the prevalence of toxic Al3+. Most genotypic variation for acid soil-tolerance in wheat is linked with the Al3+-activated efflux of malate anions from roots which ... -
Plant life in campo rupestre: New lessons from an ancient biodiversity hotspot
Morellato, L. Patrícia C.; (Flora: Morphology, Distribution, Functional Ecology of Plants, 2018) [Artigo]
The years 2011–2020 represent the United Nations Decade of Biodiversity, aiming to inspire worldwide actions to support biodiversity conservation. This Special Issue illustrates the current knowledge of plant life in campo ... -
Seed bank of seasonally flooded grassland: experimental simulation of flood and post-flood
Bao, Francielli; ; de Assis, Marco Antonio ; (Aquatic Ecology, 2018) [Artigo]
Wetland seed banks comprise the propagules of plant species that have species-specific germination requirements for germination in either flooded or dry conditions. At the community level, wetland structure and succession ... -
Ecology and evolution of plant diversity in the endangered campo rupestre: a neglected conservation priority
; ; ; ; ; Carstensen, Daniel W.; ; ; ; et al. (Plant and Soil, 2016) [Resenha]
Background: Botanists, ecologists and evolutionary biologists are familiar with the astonishing species richness and endemism of the fynbos of the Cape Floristic Region and the ancient and unique flora of the kwongkan of ... -
Vochysia tucanorum Mart.: an aluminum-accumulating species evidencing calcifuge behavior
; Habermann, Gustavo; do Amaral, Cárita Liberato ; ; ; (Plant and Soil, 2017) [Artigo]
Background and aims: Acidic soil occupies 30% of the world’s ice-free land, and exchangeable aluminum (Al) availability increases under these conditions, being toxic to many plant species. However, some plants accumulate ... -
