  1. Physical ecology of hypolithic communities in the central Namib Desert: The role of fog, rain, rock habitat, and light by Warren-Rhodes, K.W., McKay, C.P., Boyle, L.N., Wing, M.R., Kiekebusch, E.M., Cowan, D.A., Stomeo, Francesca, Pointing, S.B., Kaseke, K.F., Eckardt, F., Henschel, J.R., Anisfeld, A., Seely, M., Rhodes, K.L.

    Published 2013
    “…We measured 0.1% of incident sunlight as the lower limit for hypolithic growth on quartz rocks in the Namib and found that uncolonized ventral rock surfaces were limited by light rather than moisture. In situ monitoring showed that although rainfall supplied more liquid water (36 h) per event than fog (mean 4 h), on an equivalent annual basis, fog provided nearly twice as much liquid water as rainfall to the hypolithic zone. …”

  2. Pathogenicity of Heterorhabditis bacteriophora in ultraviolet light–irradiated agar suspension on Spodoptera frugiperda (Lepidoptera: Noctuidae) larvae by Pérez Tesén, Edgar Darwin, Rodas Adrianzén, Jennifher Elizabeth, Chávez Cabrera, Alexander, Neira de Perales, María Elena

    Published 2023
    “…Their efficacy, however, is affected by abiotic conditions including ultraviolet (UV) light and desiccation. It is therefore necessary to develop formulations that preserve or extend the viability of the agent or product while facilitating ease of application. …”

  3. Do light and alfalfa responses to cloth and slatted shade represent those measured under an agroforestry system? by Costa Varella, Alexandre, Moot, Derrick, Pollock, K.M., Peri, Pablo Luis, Lucas, R.J.

    Published 2022
    “…It produces a continuous, uniform reduced light environment. Shade cloth and a slatted structure were compared in relation to the inability to represent the light regime and plant responses of an agroforestry system. …”

  4. A practical guide to estimating the light extinction coefficient with nonlinear models—a case study on maize by Lacasa, Josefina, Hefley, Trevor J., Otegui, María Elena, Ciampitti, Ignacio A.

    Published 2021
    “…The fraction of intercepted photosynthetically active radiation (fPARi) is typically described with a non-linear function of leaf area index (LAI) and k, the light extinction coefficient. The parameter k is used to make statistical inference, as an input into crop models, and for phenotyping. …”

  5. Multi-sensor airborne lidar requires intercalibration for consistent estimation of light attenuation and plant area density by Maurent, Eliott, y siete autores más

    Published 2023
    “…Neglecting the dependency of apparent light attenuation on scanner properties may lead to biases in estimated vegetation density commensurate to those affecting light attenuation estimates. …”

  6. Sustainable Forests? : values, perceptions and expectations among three stakeholder groups in the light of the Swedish bioeconomy transition by Stenius, Tove

    Published 2017
    “…The research is conducted in the light of the National Forest Program, which is currently being developed for the government through a series of working group processes, where a transition from a dependency on fossil fuel towards bioeconomy is highlighted as one of the driving motives behind the program. …”

  8. The effect of a lowered light intensity at night on cow traffic and milk yield in automatic milking systems by Hjalmarsson, Fanny

    Published 2014
    “…There are many factors affecting cow traffic but one factor that has not been studied thoroughly yet is the effect of different light intensities during the night, 22.00 h to 05.00 h. …”
