Strong disease pressure in nature can drive the evolution of plant resistance traits. However, the expression of resistance is not constant over a plant's life-history. Instead, a frequently observed pattern in crops and wild plants is that seedlings and young plants are much more susceptible to disease than older, mature plants. But why? Getting infected as a seedling prior to reproduction is often far worse for an individual plant's fitness than getting infected as an adult after having a chance at flowering. In the talk I will explore several hypotheses concerning the evolution of age-specific disease resistance in wild carnations (Dianthus pavonius) and campions (Silene latifolia) to a sterilizing fungal pathogen (Microbotryum, the causal agent of 'anther-smut disease'). The talk will draw on observations of disease dynamics in wild populations in the alps, as well as greenhouse studies of susceptibility and tradeoffs.? ------------------------------------------ UC Santa Cruz botanist names two rare succulent species https://www.mercurynews.com/2023/02/03/uc-santa-cruz-botanist-names-two-rare-succulent-species/ Biden Bans Roads and Logging in Alaska?s Tongass National Forest https://www.nytimes.com/2023/01/25/climate/alaska-tongass-national-forest.html John L.

As we have been doing for some years, there will be two Saturday trips to Bear Island at Great Falls with a trip to Turkey Run in between. In addition, there will be a trip a bit further afield out near Sharpsburg at Ferry Hill, above the Potomac. Bear Island - Saturdays, March 25 and April 8 Turkey Run - Saturday, April 1 Ferry Hill - Saturday, April 22 A bit of early Hepatica was on display Thursday at Ferry Hill: http://botsoc.org/hepatica20230209_145105.jpg --------------------------------------------------------------- Dues for 2023 There are two ways to pay Botanical Society of Washington 2022 Dues ($10 for individual or $15 for two at one address) to the Treasurer. 1) Mail check payable to Botanical Society of Washington to: Paul Peterson, 4520 Cheltenham Dr., Bethesda MD 20814 2) Pay using Venmo: Paul Peterson: @BotSoc-Wash Instructions for those new to Venmo: 1.

Message-ID: Our next meeting will be on Tuesday, March 7 at 7pm. Doors opening by 6:45. The speaker will be Dr. Keryn Gedan from the Department of Biological Sciences at George Washington University. Title: Sea Level Rise Effects on Coastal Forest Flier: http://botsoc.org/mar23.pdf Zoom Link: https://us02web.zoom.us/j/87026031437?pwd=cll5cUJSUjNJSHc2MWpWeUFMdGorUT09 Meeting ID 870 2603 1437 Passcode 320545 Description: Ghost forests are formed when sea level rise and saltwater intrusion kill trees at the coastal ecotone. The formation of ghost forests reduces coastal forest habitat, however, it also offers an opportunity for expansion of intertidal ecosystems such as tidal marshes, which are rapidly losing habitat due to sea level rise-related drowning and edge erosion. The Mid-Atlantic coast of the US is a hot spot of sea level rise and provides a window through which to view the future of coastal change. In forest plots spanning a salinity stress gradient, vegetation monitoring and observational data paint a picture of the pace and nature of ghost forest formation. Canopy, subcanopy, and understory vegetation are rapidly changing as the forest converts to marsh. Patterns have begun to emerge, including a rapid increase in the shrub layer, as well as in the cover of a globally important invasive species, the common reed Phragmites australis. During the transition, trees provide instantaneous information about salt stress in their water use. We use sap flow sensors to investigate the effects of sea level rise of these stressed and dying trees. --------------------------------------------------------------- UC Herbarium Gets Former Cincinnati Botanist's Collection https://www.uc.edu/news/articles/2023/02/cincinnati-botanists-plant-collection-goes-to-uc-herbarium.html Diederik De Jong 1932-2016 "Diederik and I played tennis with a group at Camargo Tennis Club for many years. Not knowing that he had passed, I was thinking of him yesterday while looking out in my yard at a 50 foot oak tree that's existence I owe to Diederik. I had dug up an oak sapling in my yard with hopes of transplanting it to a more suitable spot but all the dirt fell off the roots. I tossed the sapling aside but told Diederik of my transplanting misadventure. My tennis / botanist friend said "That tree is not dead. Go home and replant it." I did. the tree looks great and will outlive both of us! Thanks Diederik and God bless."
