Supercontinuum Lidar for Spectroscopic Sensing Applications [PDF]

open access: yes, 2023
Light detection and ranging (lidar) is a well established optical remote sensing technique with varying applications including atmospheric, environmental, automotive and other industrial applications. Lidar generally employs a monochromatic light source,

Hyperspectral lidar for monitoring high-resolution activity patterns of African stingless bee species

open access: yesAnimal Biotelemetry
Background Stingless bees are vital pollinators and honey producers in the tropics. Research on stingless bees is generally underrepresented compared to the western honeybees, and while stingless bee studies from some regions are reported, there is a ...

Numerical simulation for identification of insects using a cw lidar system [PDF]

open access: yes, 2017
Mosquitos are the most common vector of disease in the world, causing millions of deaths a year. While curing the diseases they cause is one approach to this problem, another could be to avoid the mosquitos in the first place.

Continental-scale patterns in diel flight timing of high-altitude migratory insects [PDF]

open access: yes
Many insects depend on high-altitude, migratory movements during part of their life cycle. The daily timing of these migratory movements is not random, e.g. many insect species show peak migratory flight activity at dawn, noon or dusk.

Collateral damage from agricultural netting to open-country bird populations in Thailand [PDF]

open access: yes, 2022
Nets are used across a wide variety of food production landscapes to control avian pests typically resulting in deaths of entangled birds. However, the impact of nets on bird populations is a human–wildlife conflict that remains mostly unquantified. Here,

Coherent Backscattering from Free-Flying Insects : Implications for Remote Species Identification [PDF]

open access: yes
The alarming decline in global insect populations and diversity calls for improvedmonitoring methods with species specificity. Conventional trapping techniques arelabor-intensive and fail to provide real-time in situ data on species composition ...

Bats as potential suppressors of multiple agricultural pests : A case study from Madagascar [PDF]

open access: yes, 2018
The conversion of natural habitats to agriculture is one of the main drivers of biotic change. Madagascar is no exception and land-use change, mostly driven by slash-and-burn agriculture, is impacting the island's exceptional biodiversity.
