Insect collapse: 'We are destroying our life support systems'

Paper: Climate-driven declines in arthropod abundance restructure a rainforest food web

https://www.pnas.org/content/115/44/E10397


Comparison of the average dry-weight biomass of arthropods caught per 12-h day in 10 ground (A) and canopy (B) traps within the same sampling area in the Luquillo rainforest. Numbers above the bars give the mean daily catch rate in dry weight of arthropods per day for the respective dates. Data for 1976 and 1977 are from Lister (22).

How Many Birds Disappear Between Migration Seasons? We Now Have a Clue.

https://www.audubon.org/magazine/winter-2018/how-many-birds-disappear-between-migration?ms=digital-eng-email-ea-x-engagement_20190119_dissapearing-birds_medium&utm_source=ea&utm_medium=email&utm_campaign=engagement_20190119_dissapearing-birds&utm_content=medium

Quote: "Their findings show a titanic drop-off of 2.6 billion birds between fall and spring ?migrations. What's more, though species that winter in the United States have shorter fall flights, they suffered the bulk of the losses, indicating that northern populations face greater threats than those in the tropics."

Feathers: Better than Velcro?

https://www.sciencedaily.com/releases/2019/01/190116150632.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Fplants_animals%2Fbirds+%28Birds+News+--+ScienceDaily%29


You may have seen a kid play with a feather, or you may have played with one yourself: Running a hand along a feather's barbs and watching as the feather unzips and zips, seeming to miraculously pull itself back together. That "magical" zipping mechanism could provide a model for new adhesives and new aerospace materials, according to engineers at the University of California San Diego.

Paper: Scaling of bird wings and feathers for efficient flight - http://advances.sciencemag.org/content/5/1/eaat4269

Fig. 6 Barbules as connecting elements between feathers.
Their spacing is measured as the distance between barbules, as shown in (A). An additively manufactured bioinspired model (B) demonstrates the function of the barbule membrane flaps. This model is shown with air blown dorsally [as in the wing upstroke (C)] and ventrally [as in the downstroke (D)] at the vane. Blue circles represent the location of airflow. Micrographs of the feather vane of Anna's hummingbird (Calypte anna) (left) and the Andean condor (Vultur gryphus) (right) demonstrate dimensional similarities on the microscale (E), while macroscale differences are shown in (F). A single barbule is highlighted in yellow in each image shown in (E). Images were taken from (30).

Spectral sensitivities of avian cones and multispectral camera channels. Solid lines show spectral sensitivities of avian cones and dashed lines show multispectral camera channels. Most terrestrially foraging birds are tetrachromats, having L, M, and either S(U) and U or S(V) and V cones6. L, M, S, V, and U stand for Long, Medium, Short, Violet, and Ultraviolet wavelengths, respectively

Newell's Shearwaters are endemic to Hawaii and face a variety of threats, but the discovery of a possible new population of Oahu is good news for the species.
