Exposure to artificial light at night mediates the locomotion activity and oviposition capacity of Dastarcus helophoroides (Fairmaire)

open access: yesFrontiers in Physiology, 2023
Light entrains the endogenous circadian clocks of organisms to synchronize their behavioral and physiological rhythms with the natural photoperiod. The presence of artificial light at night disrupts these photoperiodic cues and is currently considered to

Ground-based hyperspectral analysis of the urban nightscape [PDF]

open access: yes, 2017
Airborne hyperspectral cameras provide the basic information to estimate the energy wasted skywards by outdoor lighting systems, as well as to locate and identify their sources.

Stemming the tide of light pollution encroaching into Marine Protected Areas [PDF]

open access: yes, 2015
Open Access journalMany marine ecosystems are shaped by regimes of natural light guiding the behaviour of their constituent species. As evidenced from terrestrial systems, the global introduction of nighttime lighting is likely influencing these ...

Artificial light at night as a new threat to pollination

open access: yesNature, 2017
Pollinators are declining worldwide and this has raised concerns for a parallel decline in the essential pollination service they provide to both crops and wild plants. Anthropogenic drivers linked to this decline include habitat changes, intensive agriculture, pesticides, invasive alien species, spread of pathogens and climate change.

Optical Sky Brightness at Cerro Tololo Inter-American Observatory from 1992 to 2006

open access: yes, 2007
We present optical UBVRI sky brightness measures from 1992 through 2006. The data are based on CCD imagery obtained with the CTIO 0.9-m, 1.3-m, and 1.5-m telescopes.

Circadian Rhythms of Crawling and Swimming in the Nudibranch Mollusc Melibe leonina [PDF]

open access: yes, 2014
Daily rhythms of activity driven by circadian clocks are expressed by many organisms, including molluscs. We initiated this study, with the nudibranch Melibe leonina, with four goals in mind: (1) determine which behaviors are expressed with a daily ...

Artificial Light at Night: A New Challenge in Microphytobenthos Research

open access: yesFrontiers in Marine Science, 2020
Artificial light at night (ALAN) has been recently recognized as a globally widespread anthropogenic disturbance, characterized by different intensities and spectra, as well as spatial and temporal variability.

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal [PDF]

open access: yes, 2016
Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view ...

Human alteration of natural light cycles: causes and ecological consequences. [PDF]

open access: yes, 2016
Artificial light at night is profoundly altering natural light cycles, particularly as perceived by many organisms, over extensive areas of the globe. This alteration comprises the introduction of light at night at places and times at which it has not ...
