R. Chisolm continues the series
of 🔥 talks in SYMP21 on disease, diversity + community ecology#ESA2017 #disecol17

eco.confex.com/eco/2017/webpr…

Now up: @trvrb on the phylodynamics of influenza diversity. #ESA2017 #disecol17

Mercedes Pascual kicks off SYMP21 on viral/community diversity. Message: strain diversity much more complex than niches! #ESA2017 #disecol17

Pej Rohani: "This is the saddest part of the talk as I have to compress ~2 yrs work into a one table" I feel you #ESA2017 #disecol17 #pomp

Wow, did not know this! @NavidehNoori talking abt how measles can cause multi-year loss of immunity to other diseases 😲 #disecol17 #ESA2017

Oh wow Sky Lan showing photos some sky-high sampling of douglas fir needles up in the canopy. #disecol17 #ESA2017

Yay for plant talks in #disecol17 sessions! Sky Lan on the role of canopy structure on swiss needle cast in douglas fir 🌲 forests #ESA2017

.@TAlexPerkins talking about the challenges of disease forecasting from aggregated time series data. #ESA2017 #disecol17

Up now: @GTitcomb on watering holes as hotspots of disease transmission #disecol17 #ESA2017

J Kwan kicking off COS130 with the tick microbiome. Unexpectedly, OTU diversity *decreases* with age! Also evenness 🤔 #ESA2017 #disecol17.

Langwig reminds us to use flexible density-transmission fns! Hear hear! (This is my nerdiest soapbox) @parasiteecology #ESA2017 #disecol17

#WNS has a nonlinear density-transmission relationship. Small pops have density dependence, but saturates at large pops. #ESA2017 #disecol17

K. Langwig: Evidence shows #WNS is spread between sites during winter hibernation, possibly due to bat sickness behavior #ESA2017 #disecol17

Jolles: FIV+ lions also have higher parasite confection and more connected parasite networks. #ESA2017 #disecol17

Anna Jolles: FIV+ lions have parasites that FIV- lions don't, mix of direct + indirect effects drive this. #ESA2017 #disecol17

C. Cleveland: guinea worm has whole other (potential) host cycle - infects dogs that consume parasite-carrying fish. #ESA2017 #disecol17

Living vicariously through #Disecol17 @ESAdisease tweeters to learn about exciting #diseco research at #ESA2017. Thanks, y'all!

FACTS from A. Martin's talk
-Wombats adorable
-Mange-infected wombats heartbreaking
-Clear behavioral/metabolic effects! #ESA2017 #disecol17

Interactions Among Insects, Pathogens, and Drought in Tree Stress and Mortality Recent and widespread tree mortality events caused by drought, insects, and pathogens are now occurring globally on every forested continent, and are anticipated to increase as temperatures rise with global change. Considerable research interest has been focused on the ecological causes and consequences of these events, which are often driven by the interaction of ecophysiological stress and biotic agents of mortality (insects and pathogens). Such attention is needed for fruitful improvement of predictions for the timing, extent, and severity of these events. Our current poor ability to predict when and where trees will die in response to climate stress and attack by tree pests and pathogens generates significant uncertainty over how global change will impact forests. Widespread tree mortality at a global scale is expected to have massive ecological effects on community composition, plant and animal habits, water resources, and even the potential to alter the planetary C cycle, reducing land surface C uptake and storage, and risking a transformation of these forests from C sinks to C sources. One of the leading uncertainties in correctly projecting global climate change is the uncertainty in anticipating climate change feedbacks on the global terrestrial C budget, in part due to potential increases in forest disturbance. However, improving predictions, and ultimately management actions that mitigate such disturbance, has been hampered by a predominately disciplinary research approach. Yet, tree mortality in most forests is driven by a combination of abiotic (climate stress) and biotic (insect and pathogen) interactions. Given the need to anticipate the effects of global change on forests, a cross-disciplinary approach to understanding the interactions of drought, pests, and pathogens will be necessary to develop predictive models of forest change in response to multiple drivers. In this session we aim to bring tree physiologists, forest entomologists, forest pathologists, and those working at the intersection of these fields together to share recent research results and interdisciplinary approaches to understanding tree mortality. We aim to challenge speakers to identify limitations that could be overcome with a cross-disciplinary approach. Speakers in this session will address: physiological tree stress on pest and pathogen defenses, insect-pathogen-plant interactions as drivers of climate-related tree mortality, ecosystem management where disease control is one factor in a multi-faceted management framework, drought effects on pathogen biology, signaling between defensive biochemical pathways and plant stress, and development of modelling approaches.

Some cool #disecol17 talks in this session organized by @forestpathogens Tues afternoon #ESA2017
