Towards improving the assessment of rainforest carbon : complementary evidence from repeated diameter measurements and d...
...
We explore whether a growth-ring analysis can produce additional information about carbon budgets in tropical forests. Such forests are characterized by a high number of species and by trees that rarely have anatomically distinct annual growth rings, which hampers the application of dendrochronological tools in carbon balance assessments in the tro...
Spatiotemporal variability of snowfall and its concentration in northern Xinjiang, Northwest China
This study investigated the spatial and temporal variability of snowfall and its concentration across northern Xinjiang, Northwest China based on the corrected dataset (derived from 26 stations) using a wet-bulb temperature method during the snowfall hydrological years from 1961 to 2017. The snowfall concentration was analyzed by means of three ind...
Soil thawing regulates the spring growth onset in tundra and alpine biomes
...
Soil temperature remains isothermal at 0 °C and water shifts to a liquid phase during soil thawing. Vegetation may receive this process as a signal and a key to restore physiological activity. We aimed to show the relationship between the timing of soil thawing and the spring growth onset. We estimated the delay between the soil thawing and the spr...
Sentinel-1 Data for Winter Wheat Phenology Monitoring and Mapping
The ability of Synthetic Aperture Radar (SAR) Sentinel-1 data to detect the main wheat phenological phases was investigated in the Bekaa plain of Lebanon. Accordingly, the temporal variation of Sentinel-1 (S1) signal was analyzed as a function of the phenological phases&rsquo / dates observed in situ (germination / heading and soft dough), and harv...
Wood anatomy variability under contrasted environmental conditions of common deciduous and evergreen species from centra...
...Published in Trees
Key messageWood density profiles revealed significant differences in wood formation along a precipitation gradient in the Congo Basin. The response of trees to climate change varies depending on leaf phenology properties.AbstractTropical forests face increasing pressures due to climate change and yet, the response of trees to varying climate condit...
The genetic architecture underlying diapause termination in a planktonic crustacean
Diapause is a feature of the life cycle of many invertebrates by which unfavourable environmental conditions can be outlived. The seasonal timing of diapause allows organisms to adapt to seasonal changes in habitat suitability and thus is key to their fitness. In the planktonic crustacean Daphnia, various cues can induce the production of diapause ...
Transmitted light as a tool to monitor tree leaf phenology and development applied to Quercus petraea
Better knowledge and a more complete long-term monitoring of tree species phenology and tree foliage development are crucial to accurately estimating the impact of climate change on forest ecosystems functioning and on forest species distribution. We set up global solar radiation sensors under the forest canopy and continuously recorded solar radia...
Oviposition plant choice maximizes offspring fitness in an aquatic predatory insect
© 2018, Springer International Publishing AG, part of Springer Nature. Evidence for the adaptive value of oviposition site selection in terms of increased offspring fitness is rare in predatory insects. We tested this in the damselfly Lestes macrostigma that prefers the plant Bolboschoenus maritimus. We carried out two experiments with shoots conta...
The PILOTE-N model for improving water and nitrogen management practices: Application in a Mediterranean context
In this paper we present PILOTE-N, a crop model devoted to the calculation of crop production from the joint water and nitrogen soil status effects. It is the extension of PILOTE, for contexts in which water might not be the sole limiting factor for crop yield, but the same model structure and credo of parsimonious parameterisation have been kept, ...
