Incorporating biotic interactions in phenology
… are still lacking on the methodologies studying phenology and biotic interactions. The presented extensive review on the topic allowed the identification of four broad categories of studies that have explored biotic interactions within phenology research and revealed that phenological studies of …

Aspects of coastal fynbos phenology
… three papers on different aspects of the phenology of several south western Cape coastal fynbos species, with a general introduction and conclusion I inking the three. The introduction discusses factors relating to the occurrence of summer growth in some Australian heath and Cape fynbos …

A crop phenology model for Windows
… oriented model for simulating crop and weed phenology under field conditions has been developed for educational and research purposes. The model can be used to study seasonal dynamics of crop and weed canopies which are important in controlling crop photosynthesis, evapotranspiration, …

Growth, reproductive phenology, and population structure in Syntrichia caninervis
… bryophyte of the arid Southwest. It exhibits a phenology and growth rate similar to the related species Tortula inermis. Mean growth rate was 0.29 mm +/- 0.04 (mean and S.D.). Expressing stems had a significantly greater growth rate than non-expressing stems, but no difference was detectable …

Long-term dynamics of forest phenology across the central hardwoods
… for access to high-quality habitat. Land surface phenology, the timing of annual growth cycles measured from remote sensing platforms, offers a potential proxy for forest ecosystem response to changing bioclimatic conditions that can be used for landscape-based wildlife conservation planning. …

Phenology and Population Dynamics of the Squash Bug, Anasa Tristis
A computer model that simulates the population dynamics of the squash bug, Anasa tristis DeGeer (Heteroptera: Coreidae), was constructed and used to predict the effect of various management options and environmental factors on this pest of cucurbit crops. The life-history data required for the …

Aspects of the structure and phenology of two fynbos communities
… mid-dense, proteoid shrublands are analysed. The phenology of a number of species in different growth forms is examined in terms of current hypotheses about growth form related timing of shoot growth, and general patterns of periodicity in nutrient-poor mediterranean environments. Taxa typical of …

Reproduction, settlement, and phenology of intertidal barnacles: implications for larval dispersal
… seasonal timing of reproduction and settlement (phenology); faster development rates and, for crustaceans, smaller larvae; reduced larval dispersal distances; and reduced connectivity between coastal populations. However, these predictions are largely based on laboratory and modelling studies, …

Phenology in Germany in the 20th century : methods, analyses and models
Die Länge der Vegetationsperiode (VP) spielt eine zentrale Rolle für die interannuelle Variation der Kohlenstoffspeicherung terrestrischer Ökosysteme. Die Analyse von Beobachtungsdaten hat gezeigt, dass sich die VP in den letzten Jahrzehnten in den nördlichen Breiten verlängert hat. Dieses Phänomen …

Seasons in the Stream: River Ecosystem Phenology in a Changing Climate
<p>Patterns of primary productivity are primarily dictated by seasonal factors like light availability and temperature. In small rivers, primary productivity often peaks opposite that of terrestrial ecosystems, where overhanging canopies shade the river channel impeding light reaching the water …

Phenology and branching in eight selected species of the genus Cliffortia
To date the peculiarities of the inflorescence structure in the wind-pollinated genus Cliffortia (Rosaceae), has gone unnoticed. In this study stereo microscope examination and sketching of fresh and dried specimens, combined with extensive field observations, were performed on eight species of the …

Phenology and Management of Annual Bluegrass Weevil on Virginia Golf Courses
Annual bluegrass weevil (Listronotus maculicollis Kirby) (Coleoptera: Curculionidae) (ABW) is a major pest of annual bluegrass (Poa annua L.) and creeping bentgrass (Agrostis stolonifera L.) on golf courses in the northeastern United States. The asynchronous life cycle makes managing ABW difficult, …

Drought Monitoring with Remote Sensing Based Land Surface Phenology Applications and Validation
… I have compared satellite-derived land surface phenology (LSP) to field observations of crop stages at the Maricopa Agricultural Center to achieve a better understanding of the temporal sensitivity of satellite derived phenology of vegetation and understand their accuracy as a tool for …
