Phenology Phenology is the study of periodic plant and animal life cycle events and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors (such as elevation). The word is derived from the Greek φαίνω (phainō), "to show, to bring to light, make to appear" + λόγος (logos), amongst others "study, discourse, reasoning" and indicates that phenology has been principally concerned with the dates of first occurrence of biological events in their annual cycle. Examples include the date of emergence of leaves and flowers, the first flight of butterflies and the first appearance of migratory birds, the date of leaf colouring and fall in deciduous trees, the dates of egg-laying of birds and amphibia, or the timing of the developmental cycles of temperate-zone honey bee colonies. Past records Observations of phenological events have provided indications of the progress of the natural calendar since ancient agricultural times. Modern records

robertscribbler | Scribbling for environmental, social and economic justice What is Phenology? Plants and animals have life cycle events that seemingly occur like clockwork every year: Frogs and salamanders breed and their offspring go through metamorphosis Flowers bloom Male ungulates (deer, elk, pronghorns, etc.) grow antlers to begin the rut and breeding season Birds migrate back and forth between their breeding grounds and their wintering grounds The leaves of deciduous trees change color and fall off Some mammals, such as bears, groundhogs and ground-squirrels, hibernate through the winter Butterflies go through metamorphosis How do Animals and Plants Know When to Start these Natural Events? The study of how the biological world times natural events is called phenology. Phenology Factors The three main non-biological factors that affect phenology are: Sunlight Temperature Precipitation (rainfall, snowfall, etc.) These three factors work together to determine the timing of natural events. Frogs mainly depend on temperature and precipitation to determine when to breed.
Sustainability is the investment opportunity of the year: Kurt Vogt, HSBC | The Climate Group We sat down with Kurt Vogt, Managing Director of Sustainable Financing at HSBC, to learn about the landscape of sustainable finance, and where the opportunities lie. HSBC hosted the second annual Sustainable Finance Briefing during Climate Week NYC on September 19, which focused on the latest developments in global climate finance and saw the launch of the Bonds & Climate Change: State of the Market 2016 report by the Climate Bonds Initiative. What are the barriers to investment in the low carbon economy and how can the market be reformed to scale-up climate finance? There are a couple of big opportunities I see to develop climate finance. Another challenge is making the business case for green bonds clearer. What factors have enabled the recent rapid growth in the green bonds market? In recent years we have seen several exciting trends in the green bonds market: Can you give some examples of how HSBC has promoted sustainable finance initiatives?
the consensus project Biological Calendars:The Statewide Network of OSU Phenology Gardens Special Circular 195 Biological Calendars:The Statewide Network of OSU Phenology Gardens Denise Ellsworth and Daniel A. Herms Effective monitoring is the backbone of any Integrated Pest Management (IPM) program. The use of plant phenology provides an alternative approach for predicting insect activity. The development of both plants and insects is temperature dependent; thus, phenological events of plants, such as flowering time, may accurately track degree-day accumulation and predict insect development and emergence. The Biological Calendar This intensive, long-term research project has demonstrated that phenological events occur in virtually the same order each year (Herms, 2003). The Biological Calendar can greatly ease the complex logistics of scheduling a monitoring and management program when confronted with a large number of pests.
