‘MultiTraits': an integrated R package for analysis and visualization of multidimensional plant traits

Ecography, EarlyView.
The multidimensional characteristics of plant traits and their trade‐offs are central to ecology. However, there is a lack of systematic and standardized tools for analyzing these intricate relationships. To fill this gap, we developed the ‘MultiTraits' R package, which incorporates four complementary analytical modules: competitors–stress tolerators ...

Data integration advances reproductive phenology research across temporal, spatial and taxonomic scales

Ecography, EarlyView.
Climate change is altering plant reproductive phenology; however, a scarcity of long‐term, systematic monitoring hinders our ability to quantify and predict these responses in many parts of the world. We addressed this gap by demonstrating how data integration can be used to produce a synthesised record of reproductive phenology observations (flowering

Evaluations and comparisons of rule-based and machine-learning-based methods to retrieve satellite-based vegetation phenology using MODIS and USA National Phenology Network data

International Journal of Applied Earth Observations and Geoinformation, 2020
Vegetation phenology is a sensitive indicator that reflects the vegetation–atmosphere interactions and vegetation processes under global atmospheric changes.

Climate, vegetation phenology and forest fires in Siberia [PDF]

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
A time series of 18 years of fAPAR (fraction of photosynthetically active radiation absorbed by the green parts of vegetation) data from the NOAA AVHRR instrument series was analyzed for interannual variations in the start, peak, end and length of the season of vegetation photosynthetic activity in Central and East Siberia.

Selection for persistence of endophyte‐free meadow fescue under intensive grazing versus frequent mowing

Grassland Research, EarlyView.
Cattle grazing meadow fescue pasture in remnant oak savanna near Fennimore, Wisconsin. Abstract Background Meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.) is highly adapted to managed rotational grazing systems with sufficient rest periods to promote regrowth and sward longevity.

Applicability of Green-Red Vegetation Index for Remote Sensing of Vegetation Phenology [PDF]

Remote Sensing, 2010
We evaluated the use of the Green-Red Vegetation Index (GRVI) as a phenological indicator based on multiyear stand-level observations of spectral reflectance and phenology at several representative ecosystems in Japan. The results showed the relationships between GRVI values and the seasonal change of vegetation and ground surface with high temporal ...

Human appreciation of flower colours as cultural ecosystem service in grasslands: A methodological approach

Grassland Research, EarlyView.
This literature‐based method estimates human appreciation of flower colours on target grasslands. Step 1: search literature sources (floristic surveys, national floras, web datasets and preference studies). Step 2: flower trait extraction (flower colour and area, flowering period and human colour appreciation scale).

Exploring Vegetation Phenology At Continental Scales: Linking Temperature-Based Indices And Land Surface Phenological Metrics

, 2017
Phenology is thes cience that studies the timings of recurring biological events such as leafing and blooming as well as their causes and variations in space and time. Spatially explicit environmental datasets and are key to understand phenological dynamics at continental to global scales.

Improving vegetation phenological parameterization of a land surface model [PDF]

, 2016
Abstract. The growing degree day (GDD) model and the growing season index (GSI) model are two common approaches used in various land surface models (LSMs) for simulating phenophases. The capacity of these two models for simulating phenolphases was evaluated by coupling them to a LSM (DLM: Dynamic Land Model) and validated by observation data from the ...

Urbanization and Seasonality Increase Introduced Plant Consumption by the World's Southernmost Parrot 城市化与季节性增加了全球最南端鹦鹉对引入植物的取食

Integrative Conservation, EarlyView.
Urbanization may alter bird foraging. Austral Parakeets (Enicognathus ferrugineus) in Patagonia rely on introduced plants in urban areas, especially in winter, despite preferring natives in the wild. This seasonal reliance on introduced species highlights urbanization trade‐offs and underscores the need to manage green areas with native plants to ...
