Phenology Effects on Carbon and Water Dynamics in a Pristine Boreal Fen A multi-decadal analysis from 2005-2007 & 2014-2022
… These cycle dynamics are strongly determined by plant phenology (e.g.,vascular plant photosynthesis and seasonality) and evapotranspiration (ET), next to other abiotic factors. While it is evident that climate change affects these networks of interactions, it is only poorly understood to what …

Land Surface Phenology of North American Mountain Environments Using the Terra Moderate Resolution Imaging Spectroradiometer
Monitoring and understanding plant phenology is becoming an increasingly important way to identify and model global changes in vegetation life cycle events. Although numerous studies have used synoptically sensed data to study phenological patterns at the continental and global scale, relatively …

The study of phenophases of Lantana camara in some parts of Makhado Municipality; Limpopo Province, South Africa
A few strategies have been utilized in plant phenology to observe the starting date of the life cycle events and the basic temperature for development and improvement of perennial plants. The study of phenophases on plant species required clear observations, interpretations and the recording of the …

Patterns of Seasonal Variation in Diet, Abundance, and Movement of the Scarlet Macaw (Ara macao) in southern Belize
… difference in elevation. I monitored plant phenology plots (2 m x 500 m) in low (N = 6) and high (N = 6) elevation areas for a year to compare fruit abundance with macaw sightings in point counts on the plots and nearby. My point count data and historical sightings indicate strongly …

The module mir156/spl affects bixin biosynthesis pathway in annatto (Bixa orellana L.)
Annatto [Bixa orellana L. (Bixaceae)] is a woody plant species that can reach up to 6 meters in height, with a fast growth pattern. Annatto produces a main apocaterotenoid namely bixin, a unique natural dye. This compound is highly used in the textile, pharmaceutical and food industries, among …

Mono-Oxygenase Activity and Nutritional Ecology of Larvae of the Gypsy Moth, Lymantria Dispar
… moth, Lymantria dispar, exhibit certain host plant preferences: oak species are favored by all larval instars; pine may serve as an alternate host for older instar larvae, but first instar larvae suffer 100% mortality on pine (Barbosa et al., 1986). Since pine contains high concentrations of …

Evaluation of physiological traits and identification of QTLs for drought tolerance in hexaploid wheat (Triticum aestivum L.).
… conditions. In the first experiment, where plants were subjected to severe water stress, RAC875 and Excalibur (drought tolerant) showed significantly (P < 0.05) higher grain yield under cyclic water availability compared to Kukri (drought susceptible), producing 44% and 18% more grain yield …

Wild rice (Zizania Palustris) seed biology: germination under a changing climate
… rice have had a symbiotic relationship with the plant for generations. Unfortunately, numerous disturbances now threaten manoomin/psiɳ populations and there have been decreases in its abundance. Impacts to manoomin/psiɳ include anthropogenic impacts like development, pollution, and climate …

A landscape approach to forecasting climate change impacts on geographic ranges and phenologies of plants in the Washington Cascades
… to forecast the impacts of climate change on plants in the Cascade Range (Washington, USA), where rapidly changing climate and hydrology pose unique risks to features of ecosystems that are economically and culturally important. Chapter one concerns the fundamental ecological processes that …

The natural recolonisation process of the seagrass Posidonia oceanica (L.) Delile after the introduction of the Italo-algerian methane pipeline in the SW Mediterranean Sea.
… and in particular how the feedback between plant recruitment, sediment dynamics and water flow is created in this new artificial environment. The results indicated how P. oceanica recruits via vegetative fragments which break from the meadow during storms. However, vegetative recruitment …

Natural gradients in temperature and nitrogen: Iceland represents a unique environment to clarify long-term global change effects on carbon dynamics
… also strongly linked to nitrogen (N) cycling, as plant productivity, the primary source of SOC, is generally N limited in cold ecosystems. During the past decades, northern temperate and some boreal ecosystems have already been absorbing about 10% of the anthropogenic C emissions due to an …

Effects of temperature and pollinator availability on plant reproductive success in the Indiana spring ephemeral community
<p>Temperature is a key driver of phenology in both plants and insects, and even small changes in temperature can impact the reproductive success of insect-pollinated plants by influencing access to pollinator services. While it is well-established that temperature variation directly impacts the …
