Increasing forest productivity is important to meet future demand for products, and improve resilience in the face of climate change. Forest depends on many things, but timing leaf development (hereafter: “plant phenology”) especially important. However, our understanding how plant phenology affects managed forests, silviculture may turn affect phenology, has been limited because spatial scale ...

One of the key principles in rangeland management is determination of suitable times for exploitation and grazing of rangeland plants in summer and winter pasturelands. This determination of time not only prevents degradation of plant species, but also leads to optimal usage of plant yield. Multiple factors affect plant phenology among which temperature regime has the highest effect on plant de...

Plants acclimate to drought optimizing the trade-off between biomass production and water loss while ensuring their survival and reproduction. Plants also modify their growth or phenology as complementary strategies in response to stress. Despite evidence of an interaction between flowering time and plant growth response to environmental stresses, this interaction in response to drought is unde...

BACKGROUND AND AIMS Mediterranean woody plants have a wide variety of phenological strategies. Some authors have classified the Mediterranean phanaerophytes into two broad phenological categories: phenophase-overlappers (that overlap resource-demanding activities in a short period of the year) and phenophase-sequencers (that protract resource-demanding activities throughout the year). In this w...

Zhang et al. (1) report that the Tibetan Plateau experienced a continuous advancing start of green-up date (SOS) from 1982 to 2011 based on the merged Global Inventory Modeling and Mapping Studies (GIMMS)based with Moderate Resolution Imaging Spectroradiometer (MODIS) [Système Pour l’Observation de la Terre vegetation (SPOTVGT)]-based SOSs. It challenged the previous contention that plants over...

The extremely large number of leaves produced by terrestrial and aquatic plants provide habitats for colonization by a diversity of microorganisms. This review focuses on the bacterial component of leaf microbial communities, with emphasis on Pseudomonas syringae-a species that participates in leaf ecosystems as a pathogen, ice nucleus, and epiphyte. Among the diversity of bacteria that coloniz...

In this paper, we present an improved procedure for collecting no or little atmosphereand snow-contaminated observations from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor. The resultant time series of daily MODIS data of a temperate deciduous broadleaf forest (the Bartlett Experimental Forest) in 2004 show strong seasonal dynamics of surface reflectance of green, near infrar...

Crop productivity in India varies greatly with inter-annual climate variability and is highly dependent on monsoon rainfall and temperature. The sensitivity of yields to future climate variability varies with crop type, access to irrigation and other biophysical and socio-economic factors. To better understand sensitivities to future climate, this study focuses on agro-ecological subregions in ...

Phenology, or the seasonality of recurring biological events such as vegetation canopy http://www.agu.org/pubs/crossref/2006/2005JD006588.shtml (1 of 2)9/1/2006 9:19:03 AM Evaluation of the SeaWinds scatterometer for regional monitoring of vegetation phenology development and senescence, is a primary constraint on global carbon, water and energy cycles. We analyzed multiseason Ku-band radar bac...
