Assessing the performance of smoothing functions to estimate land surface phenology on temperate grassland
(Taylor & Francis, 2016-04)
NDVI (Normalized Difference Vegetation Index) time-series have beenused for permitting a land surface phenology retrieval but these timeseries are affected by clouds and aerosols,which add noise to the signalsensor. In ...
Reproductive phenology of two co-occurring Neotropical mountain grasslands
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, ...
Phenological aspects and variation of chlorophylls a and b contents in caryocar-brasiliense camb
(Inst Tecnologia Parana, 1993-03-01)
There were detected variations of chlorophylls a and b during the senescence leaves period of Caryocar brasiliense Camb in the Corumbatai cerrado vegetation, State of São Paulo. The highest peak of total chlorophylls a and ...
Preliminary study of a methodology based on the degree-days concept for predicting the phenological phases of crops
(Fundacion Romulo Raggio, 1997-01-01)
This work develops a methodology (using the degree-days concept and linear regression), to forecast the duration of phenological phases in crops. An experiment was conducted in the greenhouse with three cultivars of cowpea ...
A semiotic-informed approach to interface guidelines for mobile applications: A case study on phenology data acquisition
Portable devices have been experimented for data acquisition in different domains, e.g., logistics and census data acquisition. Nevertheless, their large-scale adoption depends on the development of effective applications ...
Phenological cycles, thermal time and growth curves of mango fruit cultivars in subtropical conditions
There are many mango cultivars available in different regions. It is about time we analysed their productive behavior in these areas, as well as their phenological performance. This study aimed to evaluate: phenological ...
Phenology patterns across a rupestrian grassland altitudinal gradient
Phenology is the study of recurrent biological events in the life cycle of organisms. For plants, reproductive events such as flowering and fruiting are critical stages in their life cycles, which also greatly affect other ...
Modeling Plant Phenology Database: Blending Near-surface Remote Phenology With On-the-ground Observations
(Elsevier Science BVAmsterdam, 2016)
The shared influence of phylogeny and ecology on the reproductive patterns of Myrteae (Myrtaceae)
1. Many factors shape plant reproductive patterns including climate, competition or attraction of pollinators and seed dispersers, flower and fruit morphologies and phylogenetic relationships. South American Myrtaceae ...
