Communities in high-stress environments (right) compared to communities in low stress environments (left) have less stable network properties. Communities under high stress are less species rich (a), less modular (b), and are less dominated by negative associations (lower negative:positive cohesion, c). The consequences for microbiomes (d) are that the reduction or loss of a taxon in response to an environmental disturbance (lightning bolt) can more easily propagate to the rest of the community (impacted taxa in black, unimpacted in gray). Positive associations (blue) are important pathways through which the effects on one taxon can cascade to impact other taxa in the community because: (1) the loss of a facilitator reduces the facilitated taxon’s fitness and/or (2) positively associated taxa are likely to be impacted by the same environmental factors (i.e., their niches strongly overlap).https://afkhamilab.com/wp-content/uploads/2019/07/picture2.pngPicture2Population persistence of endangered plant Hypericum cumicola depended on its soil microbiome across 92 sites. Integral Project Models parameterized with demographic data from experiments and the field showed that plant population growth rates only exceeded the threshold of λ=1 (i.e. the plant population was growing) when the appropriate soil microbiome was present. Population growth rates are shown projected along a fire hisotry gradient (i.e. time since most recent fire).

Each point represents the fungal community composition at a site on the experimental tree islands. Points are colored by relative water level (in meters) from high water (light colors) to low water (dark colors). The graphs on either side of the ordination indicate the mean and standard error of tree density and island core type along the first two axes of community composition (CAP1 and CAP2). Different lowercase letters denote significant differences. The table (in upper right corner) details correlations between continuous environmental variables.https://afkhamilab.com/wp-content/uploads/2021/09/kasey-paper.jpgkasey paperhttps://afkhamilab.com/wp-content/uploads/2019/08/dan-planting.jpgdan plantinghttps://afkhamilab.com/wp-content/uploads/2019/06/capture.pngCapture2022-08-16T04:56:04+00:00weekly0.6https://afkhamilab.com/63-2/2019-08-30T02:12:51+00:00weekly0.6https://afkhamilab.com/pictures/https://afkhamilab.com/wp-content/uploads/2016/10/2016-09-23-13-48-46.jpg2016-09-23-13-48-46https://afkhamilab.com/wp-content/uploads/2016/10/2016-05-03-10-28-00.jpg2016-05-03-10-28-00https://afkhamilab.com/wp-content/uploads/2016/10/2016-05-01-12-19-19.jpg2016-05-01-12-19-19https://afkhamilab.com/wp-content/uploads/2016/10/2016-05-01-12-03-09.jpg2016-05-01-12-03-09https://afkhamilab.com/wp-content/uploads/2016/10/2016-01-09-11-40-19.jpg2016-01-09-11-40-19https://afkhamilab.com/wp-content/uploads/2016/10/2016-01-09-10-42-07.jpg2016-01-09-10-42-07https://afkhamilab.com/wp-content/uploads/2016/10/2016-09-28-13-24-44.jpg2016-09-28-13-24-44https://afkhamilab.com/wp-content/uploads/2016/10/2016-09-28-09-31-52.jpg2016-09-28-09-31-52https://afkhamilab.com/wp-content/uploads/2016/10/2016-09-28-09-30-39.jpg2016-09-28-09-30-39https://afkhamilab.com/wp-content/uploads/2016/10/2016-09-28-09-30-34.jpg2016-09-28-09-30-342016-10-17T13:11:38+00:00weekly0.6https://afkhamilab.comdaily1.02026-03-06T17:08:10+00:00
