The Forest Canopy: Structure, Roles & Measurement
If you are looking for a classic example of the circle of life, consider the forest canopy structure. A forest’s canopy structure is influenced by environmental and soil factors, and it also influences these factors in return. It is an aspect of forest ecology that is receiving more attention in this age of climate change emergency. The canopy structure is often overlooked, with most of the ...

Traceflux: a small-scale tracer experiment at a forested site
Results from four successful tracer experiments carried out in a dense forest canopy are presented. For each experiment, sulphur hexafluoride SF6 was released from a point source in trunk space and air samples were collected at 19 horizontally distributed locations in the canopy. Meteorological measurements include fast-response turbulence data recorded at several locations in and above the ...

The effects of Picea schrenkiana forest litter on snow surface albedo
In this paper, we analyze the characteristics of the snow albedo of different underlying surfaces based on measurements of shortwave radiation and observations of forest litter on snow surfaces, both in an open, unforested environment and in areas with differing forest canopy openness. The fractional litter coverage was obtained through the binarization of digital photos of forest litter ...

First attempt to measure rainfall canopy interception loss, throughfall, and stemflow in Juglans regia Linn and Cup. Sempervirens L. Var. fastigiata in the north of Iran
Each individual tree significantly alters the growth of surrounding vegetation by partitioning of rainfall and nutrients to the rooting zone. The Iranian Hyrcanian forests are among one of the most fragile ecosystems of the country owing to large industrial activities for logging and extensive urbanisation. These may accelerate disturbing of this unique type of forest. Of concern currently is an ...

Forest & plant canopy analysis - Tools & methods
The range of applications of canopy cover analysis is truly astounding. Canopy analysis derives its usefulness from the vitality of the canopy. Many methods to measure canopy cover have been developed in the last 80 years to meet various objectives. Not surprisingly, there have been several comparisons of the tools in different parts of the world. A general knowledge of canopy cover and the ...

Observations and snow model simulations of winter energy balance terms within and between different coniferous forests in southern boreal Finland
Variation of canopy properties between different forest types is seldom taken into account in hydrological and climate models, and consideration of variation inside a forest is normally omitted. In this work, three data sets on near surface energy balance terms (incoming shortwave and longwave radiation; air and snow–soil interface temperatures) were collected in the southern boreal ...

Variation in photosynthetic photon flux density within a tropical seasonal rain forest of Xishuangbanna, south-western China
The effects of canopy development, solar angle, and weather conditions on temporal variation in photosynthetic photon flux density (PPFD) at three heights within a tropical rain forest canopy in Xishuangbanna, China, were examined. PPFD was measured every second and stored as 10-min averages from 1 December 2002 to 30 November 2003. PPFD variability was examined at three different tempcral ...

What are leaves and why are they important? - Case study
As a research scientist, you’ve dedicated your life to understanding and communicating details about plants that others haven’t considered in the past. Our infographic below focuses on the leaf basics: what leaves are, what they do, and why they are so important. Share it with your students, your friends and family, or just use it as a reminder of why you do what you do. Plus, ...

When planting trees does more harm than good
Note to anyone who thinks planting trees is the bees’ knees: Grasslands are important, too. With forests disappearing at record rates and the carbon sequestration and other benefits of vegetation getting increasing visibility, tree-planting has become almost an iconic “environmentally friendly” activity. But in some cases it could do more harm than good, according to Iowa State ...

The newest strategy for saving bees is really, really old
With pollinators in decline around the world, conservationists turn to traditional farmers for answers. In northwestern India, the Himalaya Mountains rise sharply out of pine and cedar forests. The foothills of the Kullu Valley are blanketed with apple trees beginning to bloom. It’s a cool spring morning, and Lihat Ram, a farmer in Nashala village, shows me a small opening in a log hive ...
