The PhD research exposed in this paper aims to develop workflows for fine scale study of climate change and its impact on agriculture using volunteered geographic information in phenology. First, a consistency checking workflow was developed to ensure the quality of volunteered observations. Next, by using novel predictors, spatio-temporal variation in plant phenology is modeled so that we can ...

BACKGROUND The impacts of climate change on phenological responses of species and communities are well-documented; however, many such studies are correlational and so less effective at assessing the causal links between changes in climate and changes in phenology. Using grasshopper communities found along an elevational gradient, we present an ideal system along the Front Range of Colorado USA ...

Optical and microwave images have been combined for land cover monitoring in different agriculture scenarios, providing useful information on qualitative and quantitative land cover changes. This study aims to assess the complementarity and interoperability of optical (SPOT-5 Take-5) and synthetic aperture radar (SAR) (Sentinel-1A) data for crop parameter (basal crop coefficient (Kcb) values an...

The identification of pod- and seed-related traits soybean genotypes their interaction with water uptake can be applied in breeding programs a view to establishing cultivars developed for the production maintenance high-quality seeds. objective was evaluate pods seeds different lignin contents after soaking periods. experimental arranged completely randomized, 7×10 factorial design, four replic...

The current study aimed to evaluate the potential of normalized difference vegetation index (NDVI), and yellowness (NDYI) derived from red–green–blue (RGB) imaging monitor growth status winter oilseed rape seeding ripening stage. Subsequently, collected values were used their correlations with yield rape. Field trials three seed densities nitrogen rates conducted for two years in Salzdahlum, Ge...

introduction lentil with about 28 percent protein occupies the second after soybean. it is one of the major crops in developing countries as a complement to cereals and is an excellent source of protein and amino acids in the diet. results of studies shown that for most crops, including lentil, the occurrence of drought stress in some phenology stages cause irreparable damages to yield. therefo...

Climate change has the potential to alter the phenological synchrony between interacting mutualists, such as plants and their pollinators. However, high levels of biodiversity might buffer the negative effects of species-specific phenological shifts and maintain synchrony at the community level, as predicted by the biodiversity insurance hypothesis. Here, we explore how biodiversity might enhan...
