Stream Our November Meeting! (WED. 11/11)

Amid COVID-19 social-distancing — This Wednesday at 6:00 PM (EDT) we will offer an online lecture of The Charleston Natural History & Audubon Society.

"The dark side of light: Artificial light as the driver for the insect apocalypse"

Join us virtually Wednesday November 11th at 6:30 pm for a lecture by Brett Seymoure global declines in insect populations and possible drivers — including artificial lighting.

Brett specializes on the importance of light for animal behavior, physiology, and community ecology. In 2016, Brett earned a PhD from Arizona State University in partnership with the Smithsonian Tropical Research Institute in Panama for studying the effects of natural light environments on butterflies. He then was a National Park Service Night Skies Postdoctoral Fellow at Colorado State University studying the effects of light pollution on organisms. He is now merging the relationship between natural light cycles and light pollution to understand the consequences of altered light regimes on biodiversity..

ABSTRACT: Insects around the world are rapidly declining. Concerns over what this loss means for food security and ecological communities have compelled a growing number of researchers to search for the key drivers behind the declines. Habitat loss, pesticide use, invasive species, and climate change all have likely played a role, but I posit here that artificial light at night (ALAN) is another important—but often overlooked—bringer of the insect apocalypse. I first discuss the history and extent of ALAN by revealing a model of global light pollution relevant to natural light cycles. Then I will discuss how bees rely upon certain light levels to become active and forage and how light pollution is likely to disrupt these natural foraging bouts. I then introduce the effects of direct light sources on moth predation in an urban environment. Lastly, I will conclude with a discussion of how artificial lights can be tuned to reduce their impact on vulnerable organismal populations..

Welcome to the Charleston, SC Audubon

We are the Charleston Natural History Society (CNHS)and  Charleston‘s Audubon society – a South Carolina chapter of the National Audubon Society since 1970. Founded as the Charleston Natural History Society in 1905, we serve Berkeley, Charleston and Dorchester counties. We are a nonprofit environmental organization that actively promotes awareness, appreciation and conservation of the natural environment through educational programs, field trips, conservation projects, sponsored research and social activities.

Support Our Audubon – Donate With PayPal!

Official PayPal Seal Note that your online transactions are protected: PayPal is among the most-trusted online pay services, and our chapter is PayPal Verified for yout assurance. For management purposes our PayPal account is managed through our chsaudubon gmail account.

National dues, our birdseed sale and Spring birdathon help our chapter operate, but we need your help to do more. Longleaf pine restoration at the McAlhany preserve, public outreach and support for conservation and environmental research and education are all valuable, and costly — and we encourage you to donate generously. Choose to give any amount you choose, donate securely through PayPal (no Paypal account required!) and rest assured that 100% of donations will be used to support the Charleston Audubon and Natural History Society Mission.

SIGN-UP NOW – Chapter News by eMail

As we take steps to reduce mailing costs and use less paper we're developing an email newsletter to keep members informed about lectures, fieldtrips, news and notes of interest. We will be greatly reducing the number of print newsletters we produce each year. Lowcountry birding and natural history notes and chapter news will be available through the web site, by email, and PDFs of the Lesser Squawk available online.

To receive emails, please sign up now!  Your information will remain private (i.e. all membership and contact information remains private and will never be sold or shared) and you unmaysubscribe at any time.

Chapter Bits + Briefs

Local membership is available by joining the National Audubon Society. Please visit our membership page online, or download a copy of our local newsletter, The Lesser Squawk, which always includes a membership application that you can cut-out and mail.

Don‘t miss our calendar page for information about our lecture series, fieldtrips and other Lowcountry events.

For over a year now we've been using a new chapter logo on our newsletters, signage and Facebook page. Designed for flexibility, we hope that this graphic can serve to identify our group for a long time to come. Different species of birds will be used in various contexts, and we hope to make the logo available to members – on t-shirts, decals, and possibly some other merchandise.
