Forest harvesting can increase solar radiation in the riparian zone as well as wind speed
and exposure to air advected from clearings, typically causing increases in summertime air …

Light is produced by changes in the energy level of electrons (when an electron changes
from a high-energy, Or excited, State to a low-energy state, Its atom will emit a photon), but …

The retrieval of canopy architectural parameters using off-the-shelf digital cameras with fish-
eye lens is investigated. The technique used takes advantage of the sensor's linear …

Forest conservation has become one of the most important environmental issues currently
facing humanity, as a result of widespread deforestation and forest degradation. Pressures …

Motivated by the needs of precise forest inventory and real-time surveillance for ecosystem
management, in this paper we present GreenOrbs [2], a wireless sensor network system and …

A correct exposure is of crucial importance for accurate retrieval of canopy parameters using
hemispherical photograph techniques. Digital hemispherical photographs were collected …

The analysis of hemispherical photographs is nowadays an established method for
assessing light indirectly and describing canopy structures. In this article, we present an …

Due to the scarcity and high cost of conventional film-based hemispherical photographic
systems, some forest scientists are now using multi-purpose, consumer-grade digital …

Leaf area index (LAI) measurements made at 17 forest sites of the Fluxnet Canada
Research Network are reported here. In addition to LAI, we also report other major structural …

Two general processes may influence gene flow among populations. One involves
divergent selection, wherein the maladaptation of immigrants and hybrids impedes gene …
